That can be answered with yes or no, depending on how you look at it.

What's your answer?

Fire Ologist February 07, 2025 at 21:34 #966446
If we couldn’t ever have made a different choice in the past, we didn’t ever make any choice at all. So because of the semantics of the question, the answer has to be “yes”.

This is a good vehicle into the underlying question, do we ever “choose” our actions? Are we agents in our own story? Is there free will? Are we capable of halting the forces of necessity to deliberately influence our self-same lives?

I have to say yes because otherwise, I am not writing this post. If the forces of nature have led me to spell the word “led” without an “a” (as in “lead, both of which follow the laws of grammar), and if I should remove “me” from the equations of this sentence, it seems to me I wouldn’t have ever noticed a difference between nature and myself in the first place and would never have seen the choice between “led” and “lead”.

If all of science was completed and reported to everyone as from God, and this report said “all moves by determined necessity and there are no choices” I would still have to choose to believe this, or not, before the motion of this thread could go about its merry way.

Depends on several factors. Ignoring choice of deterministic interpretation of things or otherwise, in what way would this entity that makes a different choice in the past be you, or relative to what would that choice be 'different'? What ties you (that choses vanilla) to the possible T-S that choses chocolate?

I didn't vote because the question was vaguely worded.

This also depends on definitions, but you seem to be using one that doesn't distinguish choice from free choice, rendering the adjective meaningless.

If I “cannot make a different choice” then there is no choice. A choice, by definition, has to involve multiple variables and a deliberative agent whose action influences the outcome among those variables. Take away the agent, and there are no longer any variables identifiable only in a deliberating agent; Take away the variables and there is no choice. So choice involves both a deliberative (free reflecting) agent, and variables.

How else can we define the moving parts of a “choice?” Maybe I have no choice but to finish this paragraph with the word “not.” Maybe the last word of this post has been predicable for ten thousand years. But it seems to me it is more likely a consequence of me and my free choices, that could go any way I am capable of bringing to effect. Maybe not.

That's a different definition, and one with which I agree. From that definition, this doesn't follow:

Quoting Fire Ologist
If I “cannot make a different choice” then there is no choice.

For example, a chess program has countless variables to ponder (at some length), and has (is) a deliberate agent whose action influences the outcome. If there was no chess program, the action would not be taken, so the influence is clearly there.

But...

given 20 identical programs with the exact same initial state, each will typically do the exact same thing.
They have choice, but not free choice since they can consider, but not actually make a different move. Your assertion presumes not choice, but free choice, which has a different definition (the one the OP uses).

Now take Schrodinger's cat (and a presumption of say Copenhagen interpretation). Given 20 identical cats in boxes with the exact same initial state, about half will die and half not. The cat thus has free choice (could have done otherwise), but sadly has no actual choice (no deliberate agency in the outcome). See the difference? One can have neither, both, or one but not the other.

You seem to be attempting to combine the two into one, with no distinction between the cases, in which case choice and free choice do not mean different things.


The OP (where's he gone?) seems to be leveraging the 'could have done otherwise' definition, not the definition you give, a 'deliberate selection from multiple options'.

Maybe the last word of this post has been predicable for ten thousand years.
I assure you otherwise. Too many people equate 'deterministic' with 'predictable'. The former is interpretation dependent (metaphysics), and the latter is very much known, and is part of fundamental theory.

This presumes an ontology where events are sorted into past, present, and future. Fine and dandy, but sans an empirical difference, I don't see the point.

But that's one version of determinism: All events share the same ontology, which means the Corvus in 2026 is no more capable of making a 'change' (as the word is used above) as the Corvus in 2020.

The usage of 'change' also implies that some future event is one thing, but later that same event is a different thing. That syntactically makes no sense. It isn't change if it was never something different.

I never think we can clarify a human behavior at issue, like choosing, by analogizing this behavior with some other type of entity’s behavior (like a chess program). We try to make black and white clarity by mixing gray with gray.

I don’t see any substantial distinction between a choice and a free choice.

In your example of what the computer is doing before it makes a move, why call that a “choice” at all? It is operating on inputs to determine the only move it must make. It is not choosing, but calculating. You said yourself its next move is determined just as it is for the other 19 identical programs. There is no agent, so there are no variables, so there is no choice.

A really good chess player is effectively calculating just as well, and his or her moves may not be choices either.

I see calling what the program does “choosing” as personifying the program. And we don’t yet know what choosing is or if we ever get to choose ourselves, so how are we to judge the program properly anyway?

Can you clarify the difference between a choice and a free choice, and deterministic mo choice using only human behavior as an example?

There are only three types of time perceptions we have. Past, Present and Future.

Past come from the memory i.e. remembering the events in the past. Present comes from our live perception happening now with consciousness for the now. Future comes from our imagination.

If you lost all your memories, then you don't have the past. If you can't imagine, then you don't have any ideas about the future. If you are not conscious, you don't have the present, past or future.

You can only make choices for now. You could also plan to make choices for your future using your imagination and thoughts.

I never think we can clarify a human behavior at issue, like choosing, by analogizing this behavior with some other type of entity’s behavior (like a chess program).
I on the other hand avoid the anthropocentric view and broaden my list of examples in order to better understand. I find the chess program to be fundamentally no different than a human in this respect.

I don’t see any substantial distinction between a choice and a free choice.
I noticed, which is why you couldn't tell apart those two very different definitions of choice. I do see a substantial distinction, and so the word 'free' becomes meaningful, and not just redundant.

In your example of what the computer is doing before it makes a move, why call that a “choice” at all?
Because it met your definition of it. I explained how when I brought up the example.


It is operating on inputs to determine the only move it must make.
No, there are many moves that it can make, and it is not compelled to choose any particular one. It evaluates each in turn and selects what it feels is a better one, all the same steps that a person does.The action (the evaluation and the selection) influences the outcome, just as your definition requires. If the choice were compelled, the program would not have influence over the outcome and would thus be unnecessary and the move would make itself, and those chess programs would be ever so much faster, and then it would not meet your definition.

It is not choosing, but calculating.
False dichotomy. Calculating (pondering, whatever) is part of the process leading to the eventual choice. It is not this or that, but rather this that leads to that.

You said yourself its next move is determined just as it is for the other 19 identical programs.
Computers tend to work best with deterministic components, even in the face of a possible non-deterministic physics. There is no 'select randomly' instruction such as is utilized by the cat in my example above. Human physiology is similar in this respect. There seems to be no components that amplify randomness or otherwise produce output that is not a function of prior state.

There is no agent
...
I see calling what the program does “choosing” as personifying the program.
Ooh, anthropomorphism again. Apparently many words only apply to humans and not anything else when doing the exact same thing. The racists used the same tactic to imply that people not 'them' were inferior.
A chess program makes its own moves, so it very much is the agent in those selections.

A really good chess player is effectively calculating just as well, and his or her moves may not be choices either.
Are we changing the definition again? Does a bad chess player make some sort of actual choice when the good one has no agency or something? Your definition wording doesn't seem to support that.

Can you clarify the difference between a choice and a free choice
Well choice is as you define it: The thing in question needs to influence the outcome (be part of, (be the primary) cause of it, given the relevant variables in the input state.

Free choice (as typically defined) means that the primary cause of the outcome did not follow from physical prior state. There is way more than one definition of free choice, but that's a common one, and it is quite distinct from your definition.
The OP doesn't mention the word 'free' at all, but does mention "could have done otherwise" which is an informal alternate definition of it.


Quoting Corvus
Present comes from our live perception happening now
Actually it is impossible to perceive the present. You speak of the fairly immediate past, which is what is typically in our active perception at any given time.

You can only make choices for now.
Choosing is a process, and thus cannot happen in an instant, so choosing is spread out over some interval of time regardless of whether you assign unequal ontology to those moments or not.

Could anyone have made a different choice in the past than the ones they made? — Truth Seeker

Unless the universe (of determinant forces and constraints on one) changes too, I don't think so.

Under any nondeterminist interpretation, one 'could have chosen differently', or even might not have faced the choice at all. It also works under some fully deterministic interpretations like MWI where all possible choices are made in some world.
The key seems to come down to the word 'anyone'. Is that person in some other world that chooses otherwise the same person as you? The answer to that is yes if you're the same person you were last week (different state of course), and no if there is no persistent identity, in which case it is hard to argue that anything makes a choice at all.


Quoting T Clark
Yes, I agree with you on this. If we're right, it seems to me the whole question of free will vs. determinism becomes trivial, pointless.

1) Determinism has little to do with free will since the typical definition of free will doesn't become free if randomness is the case instead of determinism. Determinism also has at least 4 different definitions, so that is also unclear.

I'll go over the physics again, becasue I think it a point worth making.

The universe is not deterministic in the way Newtonian physics suggested. It's not that we could measure the position of everything in the universe to any arbitrary level of precession. If we measure the momentum of an object to a greater degree of precession, we loose precession in the measurement of it's position. We can't have both.

Supose we take the universe back to before Reply to Truth Seeker did the OP, and ask, if we did it again, would everything happen in the exact same way? And here we might be asking one of two different things. If you are asking us to take the universe back to the exact same state as it was before the OP, and set it rolling again, then physics says that the notion of "the exact same state" does not make sense, because there can be no such measurement of the state of the universe. But if you are imagining not a physical state but a modal state, the universe just as it was, then of course the exact same thing would happen again... becasue that is what you are supposing in your modal ruminations.

What determines who chooses what? If the choices are determined by genes, environments, nutrients and experiences, are the choices free?

Quoting Truth Seeker
Are we free agents or are our choices determined by variables such as genes, environments, nutrients, and experiences?
Depends on one's definition of 'free'. A compatibilist would say yes even if physics is fully deterministic, but a compatibilist might have a completely different definition of 'free' than somebody wanting to rationalize a different view.
A better definition is 'not compelled by something not you'. Nothing in a deterministic universe compels a different decision than the one you want. Hence compatibilism.

OK, your second quote there implies that 'free' means at least "not determined by that list of variables", in which case probably not, but why in the world would you want that kind of 'free'? Sounds like a formula for horrible choice making.

If I had the genes of a banana tree instead of my genes, could I have typed these words? I don't think so.
Your genes influence your general makup (what you grew up to be), but are for the most part not consulted in any way for making a particular decision.
If you were conceived with banana genes, then you'd have grown up into a banana plant. But if your human genes were all suddenly switched into banana genes shortly before ordering ice cream, you'd probably pick the same flavor, and only later get sick and die because you are failing as a banana plant. Not a biologist, so I don't know how fast it would happen, but it would very much happen.

Quoting Truth Seeker
What I am exploring here is whether our choices are inevitable or not.
This has to do with which interpretation of physics (if any of the known ones) happens to be the case. In some, yes, all inevitable.There are several definitions of 'determined' and several of them need to be not the case for the sort of 'free' that you seem to have in mind. Most non-deterministic interpretations are alternatively fundamentally random, which doesn't allow any more freedom than a non-random interpretation. Rolling dice is a very poor way to make decisions that matter, which is why there are no structures in human physiology that leverage natural randomness. And there very much would be such structures if there was useful information to be found in it. Evolution would not ignore any advantage like that.

I think a better way to think of it is that the real world is run by randomness constrained by deterministic processes.

There are two ways, both impractical to (currently) impossible. First one could predict with 100% accuracy, outcomes from detailed knowledge of the brainstate before the "decision" was made or second, if you could set up more than one example of identical brainstates then demonstrate that they always make the same "decision".

However, in my opinion, there are too many examples of "close enough" scenarios of the second situation resulting in wildly different outcomes to personally believe in Determinism.

Of course they do. Free choice is not needed at all for that. Common misconception. It is only needed for external responsibility (like responsible to some entity not part of the causal physics), but it is not needed to be held responsible by say my society, which IS part of the universe.

I didn't read it that way. No explicit mention of retrocausality, only the proposal that it might have possibly evolved differently from some given prior state. That answer is, as I said, a matter of interpretation. BTW, any non-local interpretation allows some retrocausality, but does not allow information to go back. So some occurrence might be a function of some event that has not yet happened (interpretation of delayed choice experiments), but a message cannot be sent to the past by such a mechanism, and to 'change the past' would seem to require the latter ability.

imo counterpart choices in 'parallel / possible worlds' are not relevant to the question at hand.
It is a different evolution of some same initial state. I find that relevant, but since that person in the other world is arguably not 'you', then 'you' didn't do the other thing. You can't both have chosen both vanilla and chocolate (twist is a third choice, not 'doing otherwise').

Our choices are never free from prior causes such as our genes, our environments from conception to the present, our nutrients from conception to the present and our experiences from the womb to the present. While we make voluntary choices, no one chooses their genes, their early environments, their early nutrients and their early experiences. As older children and adults we have limited choices about our environments, nutrients and experiences but even these limited choices are never free from the variables of genes, environments from conception to the present, nutrients from conception to the present and experiences from conception to the present.

Apparently many words only apply to humans and not anything else when doing the exact same thing.


No one can clearly state what they are doing when they claim to make a choice - it’s a few thousand year old debate. So how can anyone say this yet to be determined thing called “choosing” is “doing the exact same thing” as anything else?

In order for the program to make a move, it needs to have been given its programming; there need be no agent inserted into the program so that the chess pieces move. Once the program moves a piece, if you deconstructed the cause of that move, you could all the code and never see any agent influenced anything.

Maybe the same is true for people. But then there is no such thing as choosing (because there is no agency).

Quoting noAxioms
Calculating (pondering, whatever) is part of the process leading to the eventual choice.


Then you assert a dichotomy, a distinction, between calculating, which is a process before, and choice which would come after (eventually). So it’s not a false dichotomy by what you say. When a program is done calculating, it has no choice but to display the answer or make the move. Choice is something else than the calculations that might precede it.

Choice is a pickle. But if we have the ability to make a choice, we must be a free agent in some sense. Otherwise, we are playing word games to make ourselves think our choices (or programmatic choices) exist.

So is it the same question to ask myself “given all that has preceded me, would I do anything else besides type this post? Could I do anything else besides repeat your words “would I not have typed your post…?”

So since I am the same as me, does it help me to understand a moment when I choose? It doesn’t. I still don’t understand how I am free to choose, nor how these words here are determined. Neither are clear.

My current answer is that, somehow, our brains kick out an awareness of awareness - we are once removed from ourselves (which gives us the concept of “self” to look back on). We can reflect. This happens outside of the normal causal chain, and builds a space for choice. This is such a fragile happening, environments and nutrients etc are suspended with it, and so our choice comes from this new space outside of ourselves (from nowhere). So we build the free agent we are in the act of asserting a “choice” in the causal chain. We are not free to choose until we just choose.

All the things you come up with as determinants and the prior causes don't allow you to have options.  Therefore they are irrelevant for making choices.

Please tell me more about the 4 different kinds of determinism. Thank you.

I actually came up with six, but the first four are the important ones.

1) determinism.as not-dualism
I googled 'determinism' and got this: "all events in the universe are caused by prior events or natural laws ". This is probably the primary definition used when asserting a dichotomy between determinism vs dualistic free will, the latter being defined as choices made by supernatural causes. The word, used in this way, seems to be a synonym for naturalism.
This sort of free will is required to be held responsible by any entity not part of the natural universe (God). It is in no way required for internal responsibility (to say society).


There are a couple that come from science, two from quantum interpretations, which is deemed deterministic if it doesn't involve fundamental randomness or 'god rolling dice' as Einstein put it.
2) Bohmian mechanics:
This is a hard deterministic interpretation that says that the universe is in a defined state at a given time (few other interpretations accept that), and that subsequent states yield one inevitable result. The state of the entire universe matters including future states since retrocausality is not ruled out. It posits hidden variables to resolve conflicts.

3) MWI
Everett's postulate is that a closed system evolves according to the Schrodinger equation, which is a fully deterministic equation. Thing is, this results in all possibilities existing, so technically an agent makes every possible choice, not just one.

4) Block universe
This view says that all events share the same ontology and thus there is no sorting into ontologically distinct categories of past, present and future. If all events exist equally, there is no way the evolution of events could be otherwise, thus every state is an inevitability.

5) Classical physics
Classical physics (Newtons laws, basic mechanics) is fully deterministic since all the equations are time reversible. There is no randomness to it anywhere. This one can be discounted because it has been proved that our universe cannot be fundamentally classical.

Edit: Wrong! Classical physics has actually been shown nondeterministic, hence should not be on my list at all.
Norton's dome is a demonstration of the indeterminacy of Newtonian physics.


6) Omniscience:
If there is an omniscient entity, then what it knows is technically an inevitability or the entity wouldn't actually be omniscient. The church has a way to explain its way around their assertion of these seemingly contradictory concepts, perhaps very similar sort explanation that discounts your suggestion above that choices made via naturalistic processes constitutes them being constrained, something with which I do not agree.



Quoting Fire Ologist
how can anyone say this yet to be determined thing called “choosing” is “doing the exact same thing” as anything else?
But you're implying that it must be the case that it is fundamentally different when you say "I see calling what the program does “choosing” as personifying the program". That was what I was balking at. Empirically, if I cannot see my opponent, I cannot tell if I am playing a human or not (hence 'doing the exact same thing'), so the usage of the word 'choose' is appropriate in either case.

In order for the program to make a move, it needs to have been given its programming; there need be no agent inserted into the program so that the chess pieces move.
All true of yourself as well. Besides, most chess playing programs don't move physical pieces, and if they do, it's an add-on (a sort of assistant), not part of the process doing the choosing (wow, just like yourself again).

Maybe the same is true for people. But then there is no such thing as choosing (because there is no agency).
Ah, so 'agency' is another one of these anthropomorphic words that is forbidden to other entities. I cannot base logic on such biases.

When a program is done calculating, it has no choice but to display the answer or make the move. Choice is something else than the calculations that might precede it.
Agree. The choice seems to be the result, possibly the output of the process, especially when it is cleanly delimited such as a chess move. A machine could choose not to display its choice of move, but that would be a bad choice since it would lose, so it seems optimal in most cases to make the move quickly. I can think of exceptions to that, but they're rare. A human is more likely to make that choice than a machine. I even witnessed exactly that a couple days ago.


I still don’t see a distinction between what a choice is, and what a free choice is.
Of course. You chose your definition that way.

But if we have the ability to make a choice, we must be a free agent in some sense.
Ah, you use the word 'free' despite the word having no distinct meaning to you. Why didn't you just say "we must be an agent'? You already put that word on the human-only list above. Now you say 'free agent' like that is distinct from just 'agent'. Be a little consistent if you're going to take this stance

Quoting noAxioms
The choice seems to be the result


A choice is what I call the result of choosing. Not any result of a calculating process. Choosing, if it exists, entails an agent who makes a free, deliberate selection among variables.

The program is not able to generate any other results, because it is not an agent capable of choosing which variable result to generate. There is always, only one move the program can make. So there is either no variables to select, or there is no agent. In the case of a program, there is no agent.

Or you didn’t explain the distinction you see well enough for my thick skull.

The word “choice”, to me, entails a free agent presented with variables who acts by selecting one variable. So saying “free” choice is redundant, as freedom is a necessary component of any choice.

Above where you defined choice and then defined free choice differently, your definition of a mere “choice” was, to me, the definition of a deterministic outcome (so not a choice at all). You didn’t define “choice” versus a “free choice”, you defined a deterministic outcome versus any choice (which always includes freedom, if choice exists at all.)

Probably, but I think it's pretty intuitive. Most people have some kind of model of causality. Counterfactual statements like mine are just the basic idea of applying the same kind of causality but changing some of the preceding conditions.

You can apply - and verify - those kind of counterfactual statements to physics simulations. "This happened this time, but if counterfactually I changed the simulation to have this bit instead, this would have happened." You could make that statement about a physics simultaion, and then you can test it. And sometimes, those statements will be right! And sometimes wrong.

Of course we don't have the straight-forward ability to test our counterfactual statements about this world, but it doesn't seem remarkably controversial to me. In fact it's part of every-day speech for most people. "That wouldn't have happened if such-and-such".

One could also imagine a godlike figure reaching in and changing a couple individual things


The Thursday angle do much for the logic which says that if you'd done differently, the whole universe would have to be different from this one.

Reply to frank in either case, counterfactuals work for a causal view of the world.

See, you can view the world as 2 things: the way the world operates, and the facts (or state) on which it does those operations. So you can reasonably say, if the state were counterfactually like X instead of what it was, then Y would have been the causal result. As long as "the way the world operates" is treated as a constant, then you can treat the state as a variable.

I agree that options are real. I have been in mazes but not labyrinths.
— Truth Seeker
Then you can always choose to do otherwise if you agree that options are real. The example of a maze is one. Think of a situation in which you have plenty of money but you are unsure about investing in the market. There are many examples in our lives in which we are unsure about the situations. This means that options in such situations are real so you can always choose to do otherwise.

I am not convinced. I have been carrying out experiments on myself for many years to see how choices are made. Every single experiment showed me that the choices arise as a result of the interactions of four groups of variables. These groups of variables are genes, environments from conception to the present, nutrients from conception to the present and experiences from conception to the present. I am 99.(an infinite number of 9s)% certain that all our choices are inevitable.

I am 100% certain of the following:

1. I am conscious.
2. I am typing in English.
3. I am not all-knowing.
4. I am not all-powerful.
5. I change.
6. I know concepts e.g. what a square or circle or triangle is.
7. I know apparent facts about reality e.g. the Earth orbits the Sun, the Moon orbits the Earth.
8. I know how to walk, run, eat, drink, cook, shop, work, read, write, type, go to the toilet, cycle, swim, etc.
9. I can't do lots of things I really want to do e.g. go back in time and prevent all suffering, inequality, injustice, and deaths and make all living things forever happy.
10. I do some things even though I don't want to do them. Here are some things I have done, currently do or will do even though I don't want to do them:

1. Breathe
2. Eat
3. Drink
4. Sleep
5. Dream
7. Pee
8. Poo
9. Fart
10. Burp
11. Sneeze
12. Cough
13. Age
14. Get ill
15. Get injured
16. Sweat
17. Cry
18. Suffer
19. Snore
20. Think
21. Feel
22. Choose
23. Be conceived
24. Be born
25. Remember some events that I don't want to remember
26. Forget information that I want to remember
27. Die

I am almost 100% certain of the following:

1. I and all the other organisms currently alive will die. Every second brings all organisms closer to death.
2. My body, other organisms, the Earth and the Universe really exist and they are not part of a simulation or hallucination or dream or illusion.
3. Other organisms e.g. humans, cows, dogs, cats, chickens, pigs, lions, elephants, butterflies, whales, dolphins, etc. are sentient beings who feel pain.
4. Being a non-consumer is more ethical than being an autotroph, being an autotroph is more ethical than being a vegan/herbivore, being a vegan is more ethical than being a vegetarian, and being a vegetarian is more ethical than being an omnivore or carnivore.
5. Gods do not exist.
6. Souls do not exist.
7. Reincarnation does not happen.
8. Resurrection does not happen.
10. Organisms evolved and were not created by God or Gods.
11. 99.9% of all the species to evolve so far on Earth became extinct in 5 mass extinctions long before humans evolved.
12. Humans and other organisms make choices but they are not free from determinants and constraints. Our choices are determined and constrained by our genes, environments, nutrients, and experiences. The reason I have put this one in the almost certain category is that it is possible, albeit extremely unlikely, that bodies, genes, cells, stars, planets, moons, galaxies, universes do not actually exist. These things could be part of a simulation or dream or hallucination or illusion I am experiencing. It is impossible to know about this with 100% certainty. I could be a solipsistic soul experiencing the illusion of being in a human body on a planet in a universe or I could be a body without any soul - I don't know these things for sure, hence I am an agnostic. There are many hypotheses that can't be tested e.g. simulation hypothesis, illusion hypothesis, dream hypothesis, hallucination hypothesis, solipsism hypothesis, philosophical zombie hypothesis, panpsychism hypothesis, deism hypothesis, theism hypothesis, pantheism hypothesis, panentheism hypothesis, etc. Just because a hypothesis can't be tested it does not mean it is true or false. It just means that it is currently untestable.

Quantum indeterminacy is irrelevant because at macroscopic levels all the quantum weirdness (e.g. quantum indeterminacy and superposition) averages out.

Only sometimes, but not the important times. There are chaotic systems like the weather. One tiny quantum event can (will) cascade into completely different weather in a couple months, (popularly known as the butterfly effect) so the history of the world and human decisions is significantly due to these quantum fluctuations. In other words, given a non-derministic interpretation of quantum mechanics, a person's decision is anything but inevitable from a given prior state. There's a significant list of non-deterministic interpretations. Are you so sure (without evidence) that they're all wrong?

Anyway, it's still pretty irrelevant since that sort of indeterminism doesn't yield free will. Making truly random decisions is not a way to make better decisions, which is why mental processes do not leverage that tool.

Neither are you. Only one choice can be made, free will or not.


Or you didn’t explain the distinction you see well enough for my thick skull.

Choice: Having multiple options available and using a natural process to select among them.
Free Choice: Having multiple options available and using a supernatural process to select among them.

It kind of comes down to your beliefs concerning the nature of your process. I have no idea why the latter renders one responsible for the choice made and the former does not. That makes no sense at all to me. It just sounds better. "Hey, the one is called 'free', so I must have it, right? Right??". The other one sounds compelled to me, despite the opposite being the case. The former is the thing in question making its own choices and the latter involves the thing being compelled by a demon that has possessed the entity, overriding what it would have otherwise chosen. That gives the demon free choice, but it takes it away from that which it has possessed.

Could anyone have made a different choice in the past than the ones they made?
I see people talking about going back in time and doing things differently. I assumed your question, to phrase it in the present, is: Given multiple options that are, in the physical sense, equally possible (for example, I am equally able to press the Netflix or Disney buttons on my remote, and I am equally able to buy the chocolate or caramel ice creams), is it possible that I might choose either? Or is only one possible, due to the hideously complex interactions of particles and structures taking place within my brain, which is really all anything amounts to, regardless of words like consciousness, perception, and memory, and which can and will work out to only one possible resolution?

I say the former. Either because that is the correct answer, or the hideously complex interactions of particles and structures taking place within my brain, which is really all anything amounts to, regardless of words like consciousness, perception, and memory, can and do work out to only that one possible resolution, every time I consider the question.

The two alternative that you are considering, one that seems to leave open alternative opportunities for choice, and the other one that portrays those choices as being pre-determined by antecedent conditions and neural events, seem not to be alternatives at all. They seem to be two compatible viewpoints, or stances, on the same decision point.

The first one is an agential stance taken by the agent themselves who are contemplating some range of opportunities.

The second one is the stance of an external observer who is singularly well informed about microscopic details of the situation but who isn't concerned with evaluating the range of opportunities for actions in terms of desirability of practical rationality.

From this spectatorial stance, it may look like only one option was predetermined but no explanation as to why it is an action of that particular kind that had to take place is in view. From the agential perspective, the sort of action that took place is intelligible in light of the agent's aims, beliefs and reasons. From this stance, the specific path that was chosen among a range of open paths was chosen by the agent, and not by external pressures and/or "internal" (i.e. neural) circumstances. The latter sorts of factors are better seen as impediments, to and/or enabling conditions of, the agent's ability to make rational decisions.

The answer depends on whether or not the Universe is comprehensively and rigidly deterministic . Current scientific understanding says it is not. But then the question is whether (assuming that our current understanding is correct) randomness on the quantum level produces a fully deterministic macro world.

I don't know the answer to that, and I doubt whether the question is even decidable in principle, because regardless of whether the macroworld is subject to randomness to a sufficient degree to make randomness operative at the macro level, knowing the answer would seem to depend on us experiencing a counterfactual reality, which is impossible in principle since anything we experience cannot rightly be thought to be a counterfactual.

I think an interesting question is, where does quantum randomness come from? There are a few interesting options, but one option in particular I personally really struggle with.

With many worlds, the randomness is actually only apparent randomness, an inevitable subjective experience but not random at all from a meta perspective.

Pilot Wave theory says there's no randomness, the conditions are there which determine any quantum result (maybe retrocausally).

Random-collapse says neither of the above are the right way to conceptualise the randomness, but in this way there are still two possibilities:

1. Non-local causal reason for why this random result was observed instead of that other random possibility. Imagine a universal random number generator that can affect quantum particles non locally.

2. Genuinely no reason at all. Literally no reason whatsoever why one random thing was observed instead of another. True ontological randomness.

I can't really wrap my head around 2. A lot of people go for #2 but, to me, literally any other possibility seems more comprehensible.

Obviously the universe just does what it does, with no concern for what I find comprehensible, so I could easily be wrong. If #2 is reality then I just don't comprehend reality. But damn, I really don't think it's #2. I'm with Einstein: things don't happen for no reason.

When it comes to a situation, you are either sure or unsure. This is a valid dichotomy. You do what you want to do if you are sure. But what about when you are unsure? I think we can agree that we all experience a sense of uncertainty in a situation, as in the maze example. That is when we say we are unsure in a situation. The important question is how could we possibly be uncertain if matter is a deterministic thing. In other words, how the sense of uncertainty is created in the brain considering that the brain is made of matter.

I don't understand why there's a problem to think about at all. Our brain doesn't have direct access to all the knowledge of the world. Our brains build models of how we think the world is, based on limited information, and sometimes those models aren't actually close to how the world is.

How are thoughts created in the brain? What is the source of the information and how the information could be processed in the brain? All we know is that there is motion of matter and change in the electromagnetic field in the brain. Without these, I am sure we can tell that no thought is possible. You have certain thoughts when you are unsure in a situation, for example when you are in a maze though. The question of how we could possibly have a sense of uncertainty when the motion of matter and electromagnetic field are deterministic is then valid.

But if the agent's aims, beliefs and reasons are nothing other than the resolution of an incalculable number of interacting physical events, then it is just physical interactions.


You can't give the whole credit for you own beliefs, aims and reasons to your physical circumstances since all three of those things are normative. If you find out that it's unreasonable for you to believe something, then you stop believing it. Likewise for your aims. And if someone finds out that a reason why they were doing something was bad, then they stop doing it. Those human rational abilities are fallible so it may happen that one holds unreasonable beliefs or makes unreasonable choices and, sometimes, one's circumstances can excuse those failures. But our physical circumstances never explain why our intentional actions are intelligible or what it is that makes those actions reasonable, when they are. Appealing to principle of evolutionary psychology, for instance, amounts to committing the naturalistic fallacy. And appealing to principles of neuroscience or physics and chemistry for explaining someone's bodily motions just amounts to changing the topic to something else. (See Ruth Garrett Millikan's paper What Is Behavior? A Philosophical Essay on Ethology and Individualism in Psychology, reprinted in White Queen Psychology and Other Essays for Alice).

So, I would claim that the agent's beliefs and reasons are something more than the resolution of an incalculable number of interacting physical events. They may be, in a sense, made up of physical things and physical events (since human beings are made up of those things) but they are made up of such ingredients organized in functional ways. Your physical constituents are organized in such a was as to enable your practical rational abilities to choose actions in light of your good reasons for doing them, and the goodness of those reasons, and their appropriateness to your circumstances, don't reduce to physical laws. Hence, the explanations why those choices were made don't reduce to physical laws either and appeals to your physical circumstances (including brain processes) oftentimes are at best, incomplete and at worst irrelevant.

That means we are dealing with options in those situations where we are not sure.


Even when we are sure about the outcomes, we are still dealing with options. For example, let's say that I am walking and I notice dog poo on the pavement. I have thought of three options in this situation:

1. Clean up the dog poo.
2. Avoid stepping on the dog poo but not clean it up.
3. Step on the dog poo.

No one is coercing me to do any of the three things so my choice to do any of them is voluntary. However, my choice is not free from determinants, constraints and consequences.

If I choose option 1, it will cost me some time, effort and a plastic bag (if I have a plastic bag with me). Doing this will prevent someone else from stepping on the dog poo.

If I choose option 2, it will save me some time, effort and a plastic bag but there is still the risk of someone else stepping on the dog poo.

If I choose option 3, it will make my shoe dirty and I will have to either clean up my shoe or throw away my shoes or keep wearing shoes with dog poo on them and spread the dog poo from my shoes to the inside of my home.

Which of the three options I select is determined by my genes, my environments from my conception to the present, my nutrients from my conception to the present and my experiences from my conception to the present.

If I had the genes of a banana tree instead of the human genes I have, I would not be sentient and would not even notice the dog poo, never mind think about my options.

If I was in a life-threatening environment e.g. someone was shooting at me with a machine gun, I simply would not give the dog poo much thought. I would be preoccupied with how I can avoid getting shot by taking cover or running erratically.

If was deprived of nutrients as a zygote, I would not even get to be born. I would have died when I was in the womb.

If I experienced an accident which caused me to go blind, I would not have even noticed the dog poo.

I could go on and on and keep listing more and more scenarios but I don't want to spend any more time explaining how we are never free from determinants, constraints and consequences. Have you understood my point? If you haven't understood it, please let me know and I will try to explain further.

What makes you so sure "options" are ontologically real things, and not just a feature of maps rather than a feature of territories?

They are real because I have had doubts in many situations in my life. It could be a feature of maps rather than territories but then we have to deal with the question I raised.

Quoting flannel jesus

And if options ARE ontologically real things, why couldn't they be physical?

I cannot see how they could be physical accepting that physical entities are deterministic by deterministic I mean that any state of matter only leads to one unique state later. If we accept that options are real in the physical world then it means that one state of matter may lead to one state or another state later and this is against the very definition of determinism.

Maybe a wave function is the physical manifestation of an option.

I believe in De Broglie-Bohm's interpretation. No Schrodinger cat paradox, no wave-particle duality, etc.

Neural nets - as in, things like Chat GPT - have doubts. They have ways of representing internal confidence levels about their models about the data they're ingesting.

https://www.lesswrong.com/posts/yzGDwpRBx6TEcdeA5/a-chess-gpt-linear-emergent-world-representation

Neural nets are implemented physically, on physical hardware.

I don't see where this assumption that doubts can't exist in a mind that's implemented physically comes from. As far as I can tell, the evidence available suggests that that's incorrect, that physical implementations of world-modeling machines can and do have doubts.

There is no objective basis for anyone to say, "yes" - even if it is true that we could have.

Consider why it seems like we could have: it's entirely in retrospect. But we're reevaluating it from our now-current mindset - not the mindset at the time of the choice.

Mindset includes one's emotional state, physical state, state of knowledge, immediate surroundings, most recent experiences. and the sequence of thoughts that led to the choice. Given all that, could we really have chosen differently? Maybe, but it is impossible to know. Hindsight doesn't establish it. We can't recreate the mindset.

But still, there were pre-existing predilections - flavors you know you like. There was a series of sights, sounds, and smells; a series of thoughts. The choice was a direct consequence. Something would need to have been different for a different choice to have been made.

Quantum indeterminacy is irrelevant because at macroscopic levels all the quantum weirdness (e.g. quantum indeterminacy and superposition) averages out.
— Truth Seeker
Only sometimes, but not the important times. There are chaotic systems like the weather. One tiny quantum event can (will) cascade into completely different weather in a couple months, (popularly known as the butterfly effect) so the history of the world and human decisions is significantly due to these quantum fluctuations. In other words, given a non-derministic interpretation of quantum mechanics, a person's decision is anything but inevitable from a given prior state. There's a significant list of non-deterministic interpretations. Are you so sure (without evidence) that they're all wrong?

Anyway, it's still pretty irrelevant since that sort of indeterminism doesn't yield free will. Making truly random decisions is not a way to make better decisions, which is why mental processes do not leverage that tool.


Thank you for the thoughtful response. You raise a key point — that in chaotic systems, even minute quantum fluctuations could, in theory, scale up to macroscopic differences (the “quantum butterfly effect”). However, I think this doesn’t meaningfully undermine determinism for the following reasons:

1. Determinism vs. Predictability:
Determinism doesn’t require predictability. A system can be deterministic and yet practically unpredictable due to sensitivity to initial conditions. Chaos theory actually presupposes determinism - small differences in starting conditions lead to vastly different outcomes because the system follows deterministic laws. If the system were non-deterministic, the equations of chaos wouldn’t even apply.

2. Quantum Amplification Is Not Evidence of Freedom:
As you already noted, even if quantum indeterminacy occasionally affects macroscopic events, randomness is not freedom. A decision influenced by quantum noise is not a “free” decision — it’s just probabilistic. It replaces deterministic necessity with stochastic chance. That doesn’t rescue libertarian free will; it only introduces randomness into causation.

3. Quantum Interpretations and Evidence:
You’re right that there are non-deterministic interpretations of quantum mechanics - such as Copenhagen, GRW, or QBism - but there are also deterministic ones: de Broglie-Bohm (pilot-wave), Many-Worlds, and superdeterministic models. None of them are empirically distinguishable so far. Until we have direct evidence for objective indeterminacy, determinism remains a coherent and arguably simpler hypothesis (per Occam’s razor).

4. Macroscopic Decoherence:
Decoherence ensures that quantum superpositions in the brain or weather systems effectively collapse into stable classical states extremely quickly. Whatever quantum noise exists gets averaged out before it can influence neural computation in any meaningful way - except in speculative scenarios, which remain unproven.

So, while I agree that quantum indeterminacy might introduce genuine randomness into physical systems, I don’t see how that transforms causality into freedom or invalidates the deterministic model of the universe as a whole. At best, it replaces determinism with a mix of determinism + randomness - neither of which grants us metaphysical “free will.”

The wiki version: https://en.wikipedia.org/wiki/Butterfly_effect
The latter link in places talks specifically about the small initial differences being different quantum outcomes. The best known quantum amplifier is Schrodinger's cat, where a single quantum event quickly determines the fate of the cat, even if it isn't hidden in a box.


Quoting Truth Seeker
1. Determinism vs. Predictability:
Determinism doesn’t require predictability. A system can be deterministic and yet practically unpredictable due to sensitivity to initial conditions.
Even classical mechanics has been shown to be nondeterministic. Norton's dome is a great example of an effect without a cause. Nevertheless, a deterministic interpretation of physics would probably require hidden variables that determine the effect that appears uncaused.


Chaos theory actually presupposes determinism - small differences in starting conditions lead to vastly different outcomes because the system follows deterministic laws.
But it doesn't require determinism. Chaos theory applies just as well to nondeterministic interpretations of physics.

If the system were non-deterministic, the equations of chaos wouldn’t even apply.
Well, deterministic equations would not apply. How about Schrodinger's equation? That function is very chaotic, and it is deterministic only under interpretations. like MWI.

2. Quantum Amplification Is Not Evidence of Freedom:
As you already noted, even if quantum indeterminacy occasionally affects macroscopic events, randomness is not freedom. A decision influenced by quantum noise is not a “free” decision — it’s just probabilistic. It replaces deterministic necessity with stochastic chance. That doesn’t rescue libertarian free will; it only introduces randomness into causation.
Agree. So very few seem to realize this.

To me, freedom is making your own choices and not having something else do it for you. Determinism is a great tool for this, which is why almost all decision making devices utilize as much as possible deterministic mechanisms such as binary logic.

3. Quantum Interpretations and Evidence:
You’re right that there are non-deterministic interpretations of quantum mechanics - such as Copenhagen, GRW, or QBism - but there are also deterministic ones: de Broglie-Bohm (pilot-wave), Many-Worlds, and superdeterministic models.
Superdeterminism is not listed as a valid interpretation of QM since it invalidates pretty much all empirical evidence. It's a bit like BiV view in that manner. The view doesn't allow one to trust any evidence.

MWI is a good example of chaotic behavior. You have all these worlds, and since weather and which creatures evolve are all chaotic functions, most of those worlds don't have you in it, or even humans. Most of those worlds don't have Earth in it. The deterministic part only says that all these possibilities must exist. There's no chance to any of them. But do they exist equally? That's a weird question to ponder.
No, I don't buy into MWI since I feel it gets some critical things wrong.

None of them are empirically distinguishable so far. Until we have direct evidence for objective indeterminacy, determinism remains a coherent and arguably simpler hypothesis (per Occam’s razor).
Of the two deterministic interpretations you mention, MWI is arguably the simplest, and DBB is probably the most complicated. This illustrates that 'deterministic' is not necessarily 'simpler'.

4. Macroscopic Decoherence:
Decoherence ensures that quantum superpositions in the brain or weather systems effectively collapse into stable classical states extremely quickly.
At least under interpretations that support collapse.

Whatever quantum noise exists gets averaged out before it can influence neural computation in any meaningful way
Yes, that what I meant by 'utilize as much as possible deterministic mechanisms'.

except in speculative scenarios, which remain unproven.
In particular, no biological quantum amplifier has been found, and such a mechanism would very much have quickly evolved if there was any useful information in that quantum noise.

Bottom line is that we pretty much agree with each other.

Reply to noAxioms Thank you very much for the fascinating links you posted. I really appreciate your thoughtful follow-up. I agree that we’re largely converging on the same view.

Regarding Norton’s dome, I think it’s an interesting mathematical curiosity rather than a physically realistic case of indeterminism. It depends on idealized assumptions (e.g., perfectly frictionless surface, infinite precision in initial conditions) that don’t occur in nature. Still, it’s a useful illustration that even Newtonian mechanics can be formulated to allow indeterminate solutions under certain boundary conditions.

As for the quantum–chaos connection, yes - Schrödinger’s cat is indeed the archetypal quantum amplifier, though it’s an artificial setup. In natural systems like weather, decoherence tends to suppress quantum-level randomness before it can scale up meaningfully. Lorenz’s “butterfly effect” remains classical chaos: deterministic, yet unpredictable in practice because initial conditions can never be measured with infinite precision. Whether a microscopic quantum fluctuation could actually alter a macroscopic weather pattern remains an open question - interesting but speculative.

I agree with you that determinism is a great tool for agency. Even if all our choices are determined, they are still our choices - the outputs of our own brains, reasoning, and values. Indeterminacy doesn’t enhance freedom; it merely adds noise.

On superdeterminism: I share your concern. It’s unfalsifiable if taken literally (since it could “explain away” any experimental result), but it remains conceptually valuable in exploring whether quantum correlations might arise from deeper causal connections. I don’t endorse it, but I don’t dismiss it either until we have decisive evidence.

You put it well: the bottom line is that we mostly agree - especially that neither pure determinism nor indeterminism rescues libertarian free will. What matters is understanding the causal web as fully as possible.

Thanks again for such a stimulating exchange. Discussions like this remind me how philosophy and physics intersect in fascinating ways.

Kind of catching up on posts made since the 8 month dormancy.

Are we free agents or are our choices determined by variables such as genes, environments, nutrients, and experiences?

Depending on definitions, the two are not necessarily exclusive.

Quoting Patterner
Not for me. I feel many choices as I'm making them. I struggle with them, looking for a reason too give one option a leg up.

There you go. You seem to have a grasp on what choice actually is.

Quoting AmadeusD
Technically, no, because the choice was made and we're not able to ever review it in this way.
Being able to review it amounts to different initial conditions.

Theoretically, I think yes. But this involves agreeing that something billions of years ago would have to have happened differently.
Billions of years?? It would be interesting, in say MWI, so see how long it take for two worlds split from the same initial conditions to result in a different decision being made. It can be one second, but probably minutes. Maybe even days for a big decision like 'should I propose marriage to this girl?'. But billions of years? No. Your very existence, let along some decision you make, is due to quantum events at most a short time before your conception.

Quoting Truth Seeker
If hard determinism is true, then all choices are inevitable
Any determinism. That is also true under what is called soft determinism.
But as you've posted, determinism has little if anything to do with free will, or with moral responsibility. Substance dualism is a weird wrench in this debate. If there are two things, only the one in control is responsible for the actions of the body. So say if I get possessed by a demon (rabies say) and bite somebody, infecting them, am I responsible for that or is the demon? Is it fair to convict a rabid human of assault if they bite somebody? Kind of a moot point since they're going to die shortly anyway.


Quoting Punshhh
But I come at this from the opposite direction, it is the constraints of the hard physical world which restrict my strong free will.
Sure. I will to fly like superman, but damn that gravity compelling otherwise.

Take that away and I would have near absolute freedom.
Take away that and there would be no you have this freedom.

Quoting Relativist
Assume the mind is not equivalent to the brain. Could you have chosen differently? You still had a set of background beliefs, a set of conditioned responses, a particular emotional state and physical state, were subject to a particular set of stimuli in your immediate environment, and you had a particular series of thoughts that concluded with the specific ice cream order that you made. Given this full context, how could you have made a different choice?

Yes. This is why determinism is irrelevant to the free will debate.
If a supernatural entity is making your choices, then not only is determinism false, but all of natural physics is false. A whole new theory is needed, and there currently isn't one proposed.

As has been pointed out, natural physics is regularly updated, and thus the current consensus view is not 'the truth'. But despite all the updates and new discoveries, one thing stands: Physics operates under a set of rules. We're still discovering those rules, but some definitions of moral responsibility require the lack of any rules. That's not ever going to be found to be the case.

Quoting LuckyR
Because you're ignoring another major factor in Human Decision Making, namely randomness.

I pretty much deny this. All evolved decision making structures have seemed to favor deterministic primitives (such as logic gates), with no randomness, which Truth Seeker above correctly classifies as noise, something to be filtered out, not to be leveraged.

Sure, unpredictable is sometimes an advantage. Witness the erratic flight path of a moth, making it harder to catch in flight. But it uses deterministic mechanisms to achieve that unpredictability, not leveraging random processes.


Quoting Truth Seeker
Regarding Norton’s dome, I think it’s an interesting mathematical curiosity rather than a physically realistic case of indeterminism.
Classical physics is a mathematical model, which some have proposed is reversible. No physics is violated by watching the pool balls move back into the triangle with all the energy/momentum transferred to the cue ball stopped by the cue.
Norton's dome demonstrates that classical mathematics is actually not reversible, nor is it deterministic, the way that the equations seem to be at first glance.


As for the quantum–chaos connection, yes
...

You have a reference for this assertion, because I don't buy it at all. Most quantum randomness gets averaged out, sure, but each causes a completely different state of a given system, even if it's only a different location and velocity of each and every liquid molecule.

Evolution depends on quantum randomness, without which mutations would rarely occur and progress would proceed at a snails pace. There's a fine balance to be had there. Too much quantum radiation and DNA gets destroyed before it can be filtered for fitness. Too little and there's no diversity to evolve something better.

Reply to noAxioms Thank you for asking for a source. You’re right that quantum effects can, in principle, influence macroscopic systems, but the consensus in physics is that quantum coherence decays extremely rapidly in warm, complex environments like the atmosphere, which prevents quantum indeterminacy from meaningfully propagating to the classical scale except through special, engineered amplifiers (like photomultipliers or Geiger counters).

Here are some references that support this:

1. Wojciech Zurek (2003). Decoherence, einselection, and the quantum origins of the classical. Reviews of Modern Physics, 75, 715–775.
Zurek explains that decoherence times for macroscopic systems at room temperature are extraordinarily short (on the order of (10^-20) seconds), meaning superpositions collapse into classical mixtures almost instantly.
DOI: 10.1103/RevModPhys.75.715

2. Joos & Zeh (1985). The emergence of classical properties through interaction with the environment. Zeitschrift für Physik B Condensed Matter, 59, 223–243.
They calculate that even a dust grain in air decoheres in about (10^-31) seconds due to collisions with air molecules and photons - long before any macroscopic process could amplify quantum noise.

3. Max Tegmark (2000). Importance of quantum decoherence in brain processes. Physical Review E, 61, 4194–4206.
Tegmark estimated decoherence times in the brain at (10^-13) to (10^-20) seconds, concluding that biological systems are effectively classical. The same reasoning applies (even more strongly) to meteorological systems, where temperature and particle interactions are vastly higher.

In short, quantum coherence does not persist long enough in atmospheric systems to influence large-scale weather patterns. While every individual molecular collision is, in a sense, quantum, the statistical ensemble of billions of interactions behaves deterministically according to classical thermodynamics. That’s why classical models like Navier–Stokes work so well for weather prediction (up to chaotic limits of measurement precision), without needing to invoke quantum probability.

That said, I fully agree with you that quantum randomness is crucial to mutation-level processes in biology - those occur in small, shielded molecular systems, where quantum tunnelling or base-pairing transitions can indeed introduce randomness before decoherence sets in. The key distinction is scale and isolation: quantum effects matter in micro-environments, but decoherence washes them out in large, warm, chaotic systems like the atmosphere.

Here are my examples:
1. We do not have a choice but to be a moral agent (not to say we will be moral, just that we either be moral or immoral).
2. We do not have a choice as to thoughts. We will have thoughts and imaginations. That's determined given our constitution.

OK, very much yes on the rapid decay of coherence. But this does not in any way prevent changes from propagating to the larger scales in any chaotic system (such as the atmosphere). Sure, a brick wall is going to stand for decades without quantum interactions having any meaningful effect, but a wall is not a particulrly chaotic system.

All three supporting only the first part I agreed with, yes. None of them support quantum differences propagating into macroscopic differences.

The question you need to ask is this: Given say MWI where you have all these different worlds splitting due to quantum events, how long does it take for classical differences to appear.
For the weather, this can take months.to be unrecognizably different. For a brick wall, probably decades. For a meteor hitting or missing Earth, probably millennia. For a human to choose one thing instead of another, maybe 10 minutes (a guess), and that depend on the gravity of the choice being made.
For the conception of a human, perhaps under a minute.

MWI is illustrative, but in any interpretation, specific quantum effects take about this long to cause or prevent these various macroscopic events.


In short, quantum coherence does not persist long enough ...

Coherence is not in any way required for quantum events to have an effect. Quite the opposite. Absent a measurement (collapse?) of some sort, quantum events can have no effect..

in atmospheric systems to influence large-scale weather patterns. While every individual molecular collision is, in a sense, quantum, the statistical ensemble of billions of interactions behaves deterministically according to classical thermodynamics.
Yes, but classical thermodynamics is a very chaotic system. Any difference, no matter how tiny, amplify into massive differences.

I agree that quantum improbability cannot be worked into weather prediction since there is no way to predict it, and weather prediction is done at significantly larger granularity, hardly a simulation at the atomic level. Hence it is good for a week or two at best. After that, you consult the farmer's almanac.

It is illuminating to track the weather prediction for a given day. It appears on my site 10 days hence. So save that prediction each day until the day in question arises. See how much the prediction changes as the day grows nearer. Sometimes it is fairly stable, but often it's all over the map, meaning they're practically guessing.

Take any choice you made in the past as an example. What were the reasons you made that choice? If given the same reasons would you have made a different choice? How and why?

It seems to me that you only realize you could have made a different choice if you had access to different information, or reasons, than you did at the moment you made the choice. As such realizing you could have made a different choice always comes after the fact that you made the choice and now know the consequences and other possible choices that could have been made (more information), that was not available at the moment of decision.

So no, you could not have made a different choice because that would have meant that you had different information than you did when you made the decision.

Well, do you know Jimmy Cricket?

Pinocchio was talked into going to a fun park instead of school, but the fun park turned into a place where children were turned into donkeys, and Pinocchio almost didn't escape.

Pinocchio was a wooden puppet, and a Blue Fairy turned him into a real boy and appointed Jimmy Cricket to help him make good decisions. A problem we have is not always knowing right from wrong. If we are lucky, we will have an uncomfortable feeling if we are considering doing something wrong, but often things are moving too fast, or we honestly believe we are doing the right thing, or we rationalize it isn't that bad, and we find out too late that it was the wrong and the consequences were that bad or worse, and then we get the uncomfortable feeling, and feelings of regret may follow. That uncomfortable feeling is like Jimmy Cricket trying to keep Pinocchio out of trouble.

Humans are pretty well programmed to be cooperative and moral, just as all social animals are programmed with social rules. But of course, things can go wrong, mostly because we don't know enough to know the right thing to do. Cicero said, “God's law is 'right reason.' When perfectly understood, it is called 'wisdom.' When applied by government in regulating human relations it is called 'justice.” Cicero

Today, we are very concerned about being smart, but unfortunately, we have neglected the need to develop wisdom. I think this cultural change leads to some serious problems, but at the same time, we have learned so many important things, and I hope this all balances out to a better future.

Truth Seeker October 14, 2025 at 17:28 #1018595
Reply to noAxioms Thank you for your thoughtful and technically well-informed reply. Let me address your key points one by one.

1. On Decoherence vs. Propagation of Quantum Effects

I agree that quantum coherence is not required for a quantum event to have macroscopic consequences. My point, however, is that once decoherence has occurred, the resulting branch (or outcome) behaves classically, and further amplification of that quantum difference depends on the sensitivity to initial conditions within the system in question.

So while a chaotic system like the atmosphere can indeed amplify microscopic differences, the relevant question is how often quantum noise actually changes initial conditions at scales that matter for macroscopic divergence. The overwhelming majority of microscopic variations wash out statistically - only in rare, non-averaging circumstances do they cascade upward. Hence, quantum randomness provides the ultimate floor of uncertainty, but not a practically observable driver of weather dynamics.

2. On the “Timescale of Divergence”

I appreciate your breakdown - minutes for human choice, months for weather, millennia for asteroid trajectories, etc. That seems broadly reasonable as an order-of-magnitude intuition under MWI or any interpretation that preserves causal continuity. What’s worth emphasizing, though, is that those divergence times describe when outcomes become empirically distinguishable, not when quantum indeterminacy begins influencing them. The influence starts at the quantum event; it’s just that the macroscopic consequences take time to manifest and become measurable.

3. On Determinism and Randomness in Complex Systems

I also agree that classical thermodynamics is chaotic, and that even an infinitesimal perturbation can, in principle, lead to vastly different outcomes. However, that doesn’t mean the macroscopic weather is “quantum random” in any meaningful sense - only that its deterministic equations are sensitive to initial data we can never measure with infinite precision. The randomness, therefore, is epistemic, not ontic — arising from limited knowledge rather than fundamental indeterminacy.

Quantum randomness sets the ultimate limit of predictability, but chaos is what magnifies that limit into practical unpredictability.

4. On Decision-Making Systems and Quantum Filtering

I completely agree that biological and technological systems are designed to suppress or filter quantum noise. The fact that transistors, neurons, and ion channels function reliably at all is testament to that design. Quantum tunneling, superposition, or entanglement may underlie the microphysics, but the emergent computation (neural or digital) operates in the classical regime. So while randomness exists, most functional systems are robustly deterministic within the energy and temperature ranges they inhabit.

* Decoherence kills coherence extremely fast in macroscopic environments.
* Chaotic systems can amplify any difference, including quantum ones, but not all microscopic noise scales up meaningfully.
* Macroscopic unpredictability is largely classical chaos, not ongoing quantum indeterminacy.
* Living and engineered systems filter quantum randomness to maintain stability and reproducibility.

So while I agree with you that quantum events can, in principle, propagate to the macro-scale through chaotic amplification, I maintain that in natural systems like the atmosphere, such amplification is statistically negligible in practice - the weather is unpredictable, but not “quantumly” so.

I really don't see how your analogy about the two rivers is relevant. The question is, could the person, at the time prior to stepping into the river, have decided at that time, not to step into the river. I think that was a real possibility to the person at that time. Therefore at that time the person could have decided not to step into it. How do you think stepping into the same river twice is relevant?

With that I will agree. It's quite a different statement than the one at which I balked before.

So while a chaotic system like the atmosphere can indeed amplify microscopic differences, the relevant question is how often quantum noise actually changes initial conditions at scales that matter for macroscopic divergence.
How often? Ever time for a chaotic system. Takes time to diverge, but given a trillion decoherence events in a marble (not even in the atmosphere) in the space of a nanosecond, there's a lot more than a trillion worlds resulting from that, and the weather will be different in all of them, assuming (unreasonably) no further splits. I mean, eventually there's only so many different weather patterns and by chance some of then start looking like each other (does that qualify as strange attractors?). But the marble has a fair chance of still being a marble in almost all of those worlds.

The overwhelming majority of microscopic variations wash out statistically - only in rare, non-averaging circumstances do they cascade upward.
This is the part for which a reference would help. Clearly we still disagree on this point. The 'butterfly effect' specifically used weather as its example. Small changes matter. Not sometime, but all of them: any difference amplifies.

2. On the “Timescale of Divergence”
...
What’s worth emphasizing, though, is that those divergence times describe when outcomes become empirically distinguishable
Well, first, to distinguish two outcomes, both must be observed by the same observer. That's not going to happen. Secondly, the butterfly can have an empirical effect immediately, but the difference is what takes perhaps a couple months.


I also agree that classical thermodynamics is chaotic, and that even an infinitesimal perturbation can, in principle, lead to vastly different outcomes. However, that doesn’t mean the macroscopic weather is “quantum random” in any meaningful sense - only that its deterministic equations are sensitive to initial data we can never measure with infinite precision.
The deterministic equations (in a simulation say) are not to infinite detail and precision, so yes, quantum effects are ignored. The real equations are not deterministic since they are (theoretically) infinitely precise, and incomplete since quantum randomness cannot be part of the initial conditions. There are probably no initial conditions. Such a thing would require counterfactual definiteness, which is possible but not terribly likely.

The randomness, therefore, is epistemic, not ontic — arising from limited knowledge rather than fundamental indeterminacy.
You don't know that. Yes, there are deterministic interpretations, but even given MWI (quite deterministic) and perfect knowledge, not even God can predict where the photon will hit the screen, and that's not even a chaotic effect.

I completely agree that biological and technological systems are designed to suppress or filter quantum noise.
Which is why a computer typically runs the same code identically every time, given identical inputs. Ditto for a brain. Both work this way even given a non-deterministic interpretation of physics.

The fact that transistors, neurons, and ion channels function reliably at all is testament to that design. Quantum tunneling, superposition, or entanglement may underlie the microphysics, but the emergent computation (neural or digital) operates in the classical regime.
Again, agree, which is why I suspect a human can be fully simulated using a classical simulation that ignores quantum effects, unless of course the human simulated happens to want to perform quantum experiments in his simulated lab.

So while randomness exists, most functional systems are robustly deterministic within the energy and temperature ranges they inhabit.
Sort of. Don't forget outside factors. My deterministic braIn might nevertheless decide to wear a coat or not depending on some quantum event months ago that made it cold or warm out today.

* Decoherence kills coherence extremely fast in macroscopic environments.
* Chaotic systems can amplify any difference, including quantum ones, but not all microscopic noise scales up meaningfully.
* Macroscopic unpredictability is largely classical chaos, not ongoing quantum indeterminacy.
* Living and engineered systems filter quantum randomness to maintain stability and reproducibility.
:up:

Mind you, I agree that not all microscopic noise scales up meaningfully, but only because many systems (bricks for instance) are not all that chaotic at classical scales. The weather is not one of them, so I deny this below:

Quoting LuckyR
Yes, that's their design. And when someone is contemplating an important decision, they bring all of that design to bear on the problem.
You make it sound so rational.
Take the 'should I cheat on my spouse' decision. I think chemistry, possibly more than rational logic, tends to influence such decisions. I wonder if robots currently can demonstrate that sort of internal conflict of interests.

What's that got to do with the what is effectively a free will/determinism debate? Free will is typically pitched as the rational side, with the chemicals often portrayed in the role of 'being compelled otherwise by physics'. Nonsense. Both are physics, and you're definitely responsible for your choice.

How much of our decision making prowess do we bring to deciding which urinal to use in the public bathroom? Very, very little. What is taking the place of that unused neurological function? Habit perhaps or pattern matching. But what about a novel (no habit nor pattern) yet unimportant "choice"? It may not fulfill the statistical definition of the word "random", but in the absence of a repeatable, logical train of thought, it functionally resembles "randomness".
Agree, until you suggest that you are actually leveraging quantum randomness when doing something like urinal selection (which definitely has rules to it, and is thus a poor example), or rock-paper-scissors, where unpredictability (but not randomness) takes the day.


If I may butt in: Quoting ProtagoranSocratist
I had no idea a single choice could occur over a period of time.
Good indication that you're talking past somebody. I also consider choice to be a process, not an event. From experimentation, it seems that it is essentially made before one becomes aware of the choice having been made, but even once made, one can change one's mind.

The question is, could the person, at the time prior to stepping into the river, have decided at that time, not to step into the river

I think that is more or less the question, but it is ill-phrased. I can answer either way.

Classically, if the state (of all of you) immediately prior to the point (and not the process) of decision was the same, it means the process was already arriving at this conclusion. How could it not act on that process, regardless of where you consider that mechanism to take place? If you don't mean the state at that point, then when?

For instance, given two identical states hours (minutes, seconds?) before the decision, could the two states evolve differently? Yea, sure. My example above about choosing to wear a coat today leverages that sort of 'deciding otherwise'. But that's a case of, immediately before the decision, the environment being different, despite identical states some time prior.

All that seems utterly irrelevant to one being responsible for the decision. If you choose to skip the coat today and you get uncomfortably cold when you go out, who's fault do you think that is? Physics or you? Free will doesn't seem to have anything to do with it.

I don't think we can accurately talk about real points within what is assumed to be a continuous process. This is the problem with representing the end of the decision making process as the "conclusion". "Conclusions" implies an end point. In reality, even as we are acting we are free to change our minds as the conditions require, so "conclusion" is arbitrarily assigned.

Therefore, to speak about a point immediately prior to the point of conclusion, really confuses the issue. When we remove those arbitrarily assumed "points", then we have a process which is in theory infinitely divisible. Then at any time in that duration the process could theoretically be changed. Even between your two arbitrary points, A being immediately prior to B, being the point of decision, there must be a duration of time during which a change in the process could occur between the arbitrarily assumed A and B.

The further problem however, would be the mechanism of such a change. Since I've already outlawed points, to get to this position, I cannot now say that the change happens at a point in between the two. This leaves a problem.

I can change my mind still during this process, saying to myself "no, it's a bad idea to do this", i made a second choice, putting an end to my "how" process. Either way, i made two choices.

1. On Decoherence and Chaotic Amplification

I appreciate your clarification. I agree that once decoherence has occurred, each branch behaves classically. My emphasis was never that quantum events never cascade upward, but that most do not in practice. Chaotic sensitivity doesn’t guarantee amplification of all microscopic noise; it only ensures that some minute differences can diverge over time. The key is statistical significance, not logical possibility.

The fact that there are trillions of decoherence events per nanosecond doesn’t entail that every one creates a macroscopically distinct weather trajectory. Many microscopic perturbations occur below the system’s Lyapunov horizon and are absorbed by dissipative averaging. The “butterfly effect” metaphor was intended to illustrate sensitivity, not to claim that every quantum fluctuation alters the weather.

So:

Yes, chaos implies amplification of some differences.
No, it doesn’t imply that quantum noise routinely dominates macroscopic evolution.

Empirically, ensemble models of the atmosphere converge statistically even when perturbed at Planck-scale levels, suggesting the mean state is robust, though individual trajectories differ. (See Lorenz 1969; Palmer 2015.)

2. On Determinism, Ontic vs. Epistemic Randomness

You’re right that we can’t know that randomness is purely epistemic. My point is pragmatic: there’s no experimental evidence that ontic indeterminacy penetrates to the macroscopic domain in any controllable way.
MWI, Bohmian mechanics, and objective-collapse theories all make the same statistical predictions. So whether randomness is ontic or epistemic is metaphysical until we have a test that distinguishes them.

Even if indeterminacy is ontic, our weather forecasts, computer simulations, and neural computations behave classically because decoherence has rendered the underlying quantum superpositions unobservable.

So I’d phrase it this way:

The world might be ontically indeterministic, but macroscopic unpredictability is functionally classical.

3. On Functional Robustness

Completely agree: both transistors and neurons rely on quantum effects yet yield stable classical outputs. The entire architecture of computation, biological or digital, exists precisely because thermal noise, tunnelling, and decoherence are averaged out or counterbalanced.

That’s why we can meaningfully say “the brain implements a computation” without appealing to hidden quantum randomness. Penrose-style arguments for quantum consciousness have not found empirical support.

4. On Choice, Process, and Responsibility

I share your intuition that a “choice” unfolds over time, not as a single instant.
Libet-type studies show neural precursors before conscious awareness, yet subsequent vetoes demonstrate ongoing integration rather than fatalistic pre-commitment.

Determinism doesn’t nullify responsibility. The self is part of the causal web. “Physics made me do it” is no more an excuse than “my character made me do it.” In either case, the agent and the cause coincide.

Thus, even in a deterministic universe, moral responsibility is preserved as long as actions flow from the agent’s own motivations and reasoning processes rather than external coercion.

5. Summary

Decoherence ? classicality; not all micro noise scales up.
Chaos ? sensitivity; not universality of amplification.
Randomness ? possibly ontic, but operationally epistemic.
Functional systems ? quantum-grounded but classically robust.
Agency ? compatible with determinism when causation runs through the agent.

Quantum indeterminacy might underlie reality, but classical chaos and cognitive computation sit comfortably atop it.
Responsibility remains a structural property of agency, not an escape hatch from physics.

I concede that the term "randomness" in the context of this conversation is not true statistical Randomness, rather a placeholder term to describe the absence of a logical train of thought as pertains to decision making, pondering, if you will. Thus I'll take your "agree"ment and call it a day.

We can cut to the chase, everyone agrees that humans ponder decisions, weigh the pros and cons of possible choices. What folks disagree on is whether this pondering is a functional illusion, such that I was always going to select chocolate, never vanilla, regardless of going through the act of pondering my "choice". In this scenario one can never go back and make a different "choice", because the concept of "choice" was an illusion. It was always going to be chocolate. Most, however believe that pondering is functionally real and thus yes, they could have selected vanilla. There is no Real World way to prove it one way or another and the answer similarly has no Real World implication since it can only be demonstrated theoretically, never in reality. But I find it more psychologically coherent to believe what I perceive, then to assume my experience is an (unprovable) illusion.

My emphasis was never that quantum events never cascade upward, but that most do not in practice. Chaotic sensitivity doesn’t guarantee amplification of all microscopic noise; it only ensures that some minute differences can diverge over time.

The mathematics says otherwise. Any quantum decoherence event, say the decay of some nucleus in a brick somewhere, will have an effect on Mars possibly within 10 minutes, and will cause a completely different weather pattern on Mars withing months. The brick on the other hand (after even a second) will have all its atoms having different individual momentums, but the classical brick will still be mostly unchanged after a year. This is a logical necessity for any quantum event. If it has no such cascading effect, then it didn't actually happen, by any non-counterfactual definition of 'happened'.


The fact that there are trillions of decoherence events per nanosecond doesn’t entail that every one creates a macroscopically distinct weather trajectory.
If it doesn't, then the event probably took place outside our event horizon, which is currently about 16 GLY away, not far beyond the Hubble sphere.

Many microscopic perturbations occur below the system’s Lyapunov horizon and are absorbed by dissipative averaging.
Sure, almost all perturbations occur below a system's Lyapunov horizon, which just means that more time is needed (couple days in the case of weather) for chaotic differences to become classically distinct.

No, it doesn’t imply that quantum noise routinely dominates macroscopic evolution
Depends on your definition of 'dominates'. Yes, the state of a chaotic system is a function of every input, no matter how trivial. Yes, they all average out and statistically the weather is more or less the same each year, cold in winter, etc. But the actual state of the weather at a given moment is not classically determined. There is no event that doesn't matter.

Coin flips are a lot like the weather. Take trillions of coins, black & white on opposite sides, and throw them on ground and look at it from an airplane. It looks gray every time, no matter how many tries you attempt. But up close, each toss is distinct, and if those distinctions amplify in a chaotic manner, different patterns will form with each toss, and those classical patterns will very much be visible for the airplane.

I was hoping for Conway's Game of Life to drive the chaos, but that game is actually not very chaotic, and the resulting patterns probably would just look mostly white from a distance with no distinct structures emerging like hurricanes.

Empirically, ensemble models of the atmosphere converge statistically even when perturbed at Planck-scale levels
Perturbations in ensemble models are far larger than Planck level. Yes, hurricanes, once formed, tend to be somewhat predictable for 8-10 days out. The perturbations are effectively running the model multiple times with minor differences, generating a series of diverging predictions. You average out those predictions to get a most probable path. Run those difference out to 3 weeks and major divergence will result.

My point is pragmatic: there’s no experimental evidence that ontic indeterminacy penetrates to the macroscopic domain in any controllable way.

Quantum theory (not any of its interpretations even) does not allow any indeterminacy to be controlled. The mathematical model from the theory also disallows any information to be gathered from the randomness. If it were otherwise, the theory would be falsified.

MWI, Bohmian mechanics, and objective-collapse theories
I hate to be a bother, but there is no collapse at all under MWI, and DBB is phenomenological collapse only, not ontic. This is a set of objective collapse interpretations posited separately by Ghirardi, Weber, Penrose.

The interpretations you list are deterministic. Most others are not. Under MWI, you could have, and actually did, choose otherwise (but was that you?). Under DBB, you could not have chosen otherwise.

.. all make the same statistical predictions.
Every interpretation makes the same statistical predictions. Superdeterminism doesn't, but it's not a valid interpretation of QM, just an alternate interpretation of the physics.

Still, I agree with your point 2. It doesn't matter whether randomness is ontic or epistemic. There will never be a test for that.


3. On Functional Robustness

Completely agree: both transistors and neurons rely on quantum effects yet yield stable classical outputs. The entire architecture of computation, biological or digital, exists precisely because thermal noise, tunnelling, and decoherence are averaged out or counterbalanced.

I agree with this, but remember that brains and computers are not closed systems, and the inputs might be subject to chaotic effects. It is the instability of those inputs that mostly accounts for a person 'having done otherwise' in two diverging worlds.


“Physics made me do it” is no more an excuse than “my character made me do it.”
See 'insanity defense', which is effectively the latter. Still responsible, but different kind of jail.

Anyway, we also seem to agree on point 4.



Quoting LuckyR
What folks disagree on is whether this pondering is a functional illusion, such that I was always going to select chocolate, never vanilla, regardless of going through the act of pondering my "choice".
The pondering is not an illusion. With the possible exception of epiphenomenalism, the pondering takes place, and the decision is the result of that. Given DBB style determinism, your decision to select chocolate was set at the big bang. Not true under almost any other interpretation, but under all of them (any scientific interpretation), the chocolate decision was a function of state just prior to the pondering, which does not mean it wasn't your decision.
Under non-QM philosophies, there's more going on than what science knows about, and all bets are off. How this makes you more responsible has never been justified to my satisfaction, but if an entity external to the universe is what's choosing chocolate, then that entity (and not the body it controls) is what's responsible to another entity also not part of the universe.

Of all that, the first paragraph is a monist take. The dualists are the ones that suggest that one is not responsible (to whom?) for their actions if the actions are due to a view with which they don't agree. All very straw man.

In this [deterministic] scenario one can never go back and make a different "choice", because the concept of "choice" was an illusion.
That's a total crock. It being a choice has nothing to do with it being deterministic or not, since choice is the mechanism by which multiple options are narrowed down to one. Your assertion makes the classical mistake of conflating a sound mechanism for selecting from multiple options, with being compelled against one's will to select otherwise, the latter of which actually does make it not a real choice, and thus takes away (not gives) responsibility.
In the end, one cannot make two choices. One cannot have chosen vanilla if chocolate was chosen, true in deterministic, random, and compelled scenarios.

Any choice making mechanism requires as much deterministic processes as possible, minimizing the randomness which is the alternative.
3rd alternative: let somebody else choose for you, which seems to make not you responsible, but rather the other person. Imagine crossing the street this way. You close your eyes and go when somebody else says to. If you get hit, it's his fault, but you still are the one enduring the consequences.

What I got from this is that choices can be broken down into sub-choices, and conversely combined into larger choices.

Of course the steps need not be thus ordered. I have pondered 'how to murder' far more often than any actual decision to go and do it, not counting all the bug smitings and mammal murders.

I think that "not being able to choose" is always there, to some degree, as what is impossible. One cannot make happen what is impossible. So as time passes what is possible, and what is impossible, is always changing. That's what change is. We make our decisions based on how we understand what is possible and what is impossible, in relation to what is wanted. We always misunderstand, to some degree.

Therefore it's always possible to choose otherwise, all the time. But some things are not possible, even if we think they are, and try to make them happen. Likewise, many things which are possible we never even consider.

Reply to noAxioms Thank you for your detailed reply.

1. On decoherence, chaos and “everything matters”
You’re right to insist that every physical event in principle influences the future state of the universe. But there are three separate claims mixed together here, and they need to be untangled:

Claim A: “Every decoherence event must produce a macroscopically different future.”*
This is false as a practical claim. Mathematically, you can map a micro-perturbation forward, but most microscopic differences remain confined beneath the system’s Lyapunov horizon and are washed out by dissipation and averaging. Saying “it mattered in principle” is not the same as “it produced a distinct, observable macroscopic outcome.”

Claim B: “If a quantum event didn’t cascade to macroscopic difference, then it didn’t happen.”
This is a category error. An event’s occurrence is not defined by whether it produces long-range, observable divergence in weather on Mars. Decoherence can and does happen locally without producing macroscopic differences that survive coarse-graining. To deny the event happened because it didn’t alter the weather is to adopt a peculiar, counterfactual definition of “happened” that isn’t used in physics.

Claim C: “Because chaotic systems amplify differences, microscopic quantum noise always matters.”
Chaos gives sensitivity to initial conditions, not guaranteed macroscopic divergence from every tiny perturbation within any fixed observational timescale. Some perturbations are amplified quickly; many are damped or trapped inside subsystems and never produce a new, robust classical structure. So yes, everything is part of the state functionally, but that does not imply practical, observable macroscopic branching for every microscopic event.

2. On ensemble forecasting and pragmatic unpredictability
Ensemble weather models show that small perturbations grow and forecasts diverge over days to weeks. That demonstrates sensitivity, not an omnipresent quantum-to-macroscopic channel that we can exploit or even detect in a controlled way. Ensemble perturbations used in practice are far larger than Planck-scale corrections; their convergence tells us about statistical predictability and model error, it does not prove ontic indeterminacy at the macroscale. In short: models are evidence of chaotic growth, not of routine quantum domination of weather.

3. Interpretations of quantum mechanics - collapse, MWI, Bohmian, etc.
Two helpful distinctions:

Predictive equivalence vs metaphysics.
Most mainstream interpretations (Copenhagen-style pragmatism, Everett/MWI, Bohmian/DBB, GRW-style objective collapse) make the same experimental predictions for standard quantum experiments. Where they differ is metaphysical: whether there is a literal branching reality (MWI), hidden variables (Bohmian), or real collapses (GRW/Penrose). That difference matters philosophically but not experimentally so far.

Determinism vs practical unpredictability.
MWI is best understood as deterministic at the universal wave function level (no collapse), while Bohmian mechanics is deterministic at the level of particle trajectories guided by the wave function. Both can produce the same Born probabilities for observable results. Objective collapse theories, if true, would introduce genuine stochastic events at the fundamental level. Superdeterminism attempts to recover determinism by postulating global correlations that undermine usual independence assumptions - but it’s philosophically and scientifically unattractive because it erodes the basis for experimental inference.

So: yes, many interpretations are deterministic; some are not. But the existence of multiple empirically-equivalent interpretations means the metaphysical verdict isn’t settled by current experiments.

4. Functional robustness (brains, transistors, computation)
Absolutely: brains and silicon devices exploit enormous redundancy and averaging to achieve robust classical behaviour despite quantum microphysics. That robustness is precisely why we can treat neurons as implementing computations without invoking exotic quantum effects. Inputs and boundary conditions matter: if an input to a brain were influenced by a huge amplification of a quantum event, your choices could track that influence, but that’s a contingent physical story, not a metaphysical proof of libertarian free will.

5. About “happening”, counterfactuals and responsibility
Two related points:

Happening and counterfactual dependence.
Whether an event “happened” should not be defined by whether it caused a macroscopic divergence millions of miles away. Physics generally treats events as happening if they leave local, causal traces (entanglement, records, thermodynamic irreversibility), not by whether they produce globally visible differences across light-years.

Responsibility and determinism.
Even if one accepts a deterministic physical description (whether classical or quantum-deterministic under MWI or Bohmian), that does not automatically dissolve ordinary moral responsibility. That’s the compatibilist position: responsibility depends on capacities, reasons-responsiveness, and the appropriate psychological relations, not on metaphysical indeterminism. Saying “my decision was set at the Big Bang” is metaphysically dramatic but doesn’t change whether you deliberated, had conscious intentions, and acted for your reason(s) - which are precisely the things our ethics and law respond to.

6. About “pondering” and the illusion of choice
You’re right to resist the crude conclusion that determinism makes choice an illusion. Choice is a process that unfolds over time; it can be broken into sub-choices and revisions. Whether decisions are determined or involve ontic randomness does not by itself answer whether they were genuinely yours. If you deliberated, weighed reasons, and acted from those deliberations, we rightly treat that as agency. Randomness doesn’t create agency; reasons and responsiveness do.

We shouldn’t conflate three different claims: (A) that micro events in principle influence the universal state; (B) that such influence routinely produces distinct, observable macroscopic outcomes; and (C) that metaphysical determinism therefore undermines agency. In practice, decoherence + dissipation + coarse-graining mean most quantum perturbations don’t make detectable macroscopic differences. Interpretations of quantum mechanics disagree about metaphysics but agree on predictions. And finally, even in a deterministic physical world, agency and moral responsibility can still be meaningful because they hinge on capacities, reasons, and psychological continuity, not on metaphysical indeterminism.

Yes, I know it isn't a true illusion. I said it's a "functional illusion", meaning that since the chocolate conclusion was set at the Big Bang (as you noted), no amount of pondering vanilla was going to result in it's selection, or at least as you correctly noted at the mind state just before the pondering started. Thus while we all agree pondering occurs, as I mentioned, folks disagree whether both sides of the internal argument can result in chocolate or vanilla on one hand or always chocolate on the other.

A distinction without importance since in reality there is no practical difference. My advice: choose the option that sits best with you worldview and move on (to questions that can actually make a difference here on planet Earth).

Claim A: “Every decoherence event must produce a macroscopically different future.”
High probability of that, but the claim is not there. Again, Norton's dome can result in the same state from multiple different initial states, thus falsifying that claim. It's a classical analysis, and it would be interesting to see if a similar scenario could be done in the quantum realm, such as different pairs of photons (coming from different directions, but with the same collective energy/momentum) combining into identical states of electron/positron pair.

None of what I posted about macroscopic differences is 'in principle'. It's very much in practice, and differences don't remain contained. All such events are beneath any system’s Lyapunov horizon and thus take at least that much time to show up as macroscopic differences.


Claim B: “If a quantum event didn’t cascade to macroscopic difference, then it didn’t happen.”
That claim presumes the principle of counterfactual definiteness (PCD) is false, which it is in almost every interpretation. But given that principle, the claim is false. I said as much in prior posts. It cascading into a macroscopic difference is way different than the difference being observed, which is of course impossible. Nobody can observe both the live and dead cat.

So the quantum event doesn't technically alter the weather since that wording implies there was one base weather that would have otherwise been. No, each event is a critical part of the cause of any sufficiently distant weather state, a very different claim than 'alters'.


Claim C: “Because chaotic systems amplify differences, microscopic quantum noise always matters.”
I think I agree with this one, with 'always' being replaced by 'always to a lot of decimal places'.

Some perturbations are amplified quickly; many are damped or trapped inside subsystems and never produce a new, robust classical structure.
Sort of. Imagine something tiny annihilating into radiation that ends up in deep space, never hitting anything. Also the tiny thing, had it not died like that, would also never have interacted with anything else. That's an example of that 'trapped', but it's also an example of an event that never happened in the absence of PCD.

Correct. None of those models run at quantum scale precision. The input data is more like data points that are kilometers apart, not nanometers apart.

More precision would be nice, but data gathering is limited and small scale differences (molecular?) make no significant difference in just the 10 days these models are good for.

Just so. This is why when you take a graduate level course in quantum mechanics, they might spend a day on interpretations, but it being philosophy, it has no scientific value. The course teaches theory, not philosophy. The determinism debate is also philosophy.

The bit I said about some events never happening? That's philosophy. Empirically, whether it happened or not is indistinguishable, so it isn't part of theory.

Determinism vs practical unpredictability.
MWI is best understood as deterministic at the universal wave function level (no collapse), while Bohmian mechanics is deterministic at the level of particle trajectories guided by the wave function.
Something like that. The wave function has multiple solutions, so DBB needs more than just that to guide particles to one outcome.

Quoting Truth Seeker
Responsibility and determinism.
Even if one accepts a deterministic physical description (whether classical or quantum-deterministic under MWI or Bohmian)
MWI is deterministic, but not classical. There's no 'you' with a meaningful identity in that view. Responsibility is a classical concept and requires a pragmatic classical view of identity, regardless of interpretations of choice.
This is not contradictory. The pragmatic part of me believes all sorts of things that the rational side of me knows is wrong. I would not be fit were the case to be otherwise. Hence my being responsible for my choices.

That’s the compatibilist position: responsibility depends on capacities, reasons-responsiveness, and the appropriate psychological relations, not on metaphysical indeterminism.
I would have said that it depends on the entity being held responsible being the same entity making the choice. Determinism just doesn't factor at all into that definition.
Compatibilism is a bit different. It asserts free will in the face of determinism. I don't, but it depends on one's definition of free will. I don't think I have free will as typically defined, but that in no way relieves me of moral responsibility since I'm still making my own choices. So I don't label myself a compatibilist.

Saying “my decision was set at the Big Bang” is metaphysically dramatic but doesn’t change whether you deliberated, had conscious intentions, and acted for your reason(s) - which are precisely the things our ethics and law respond to.
Yes. My opinion is that my decision was not at all set at the big bang, but that just means I don't buy into DBB, probably the only interpretation that suggests that.

6. About “pondering” and the illusion of choice
You’re right to resist the crude conclusion that determinism makes choice an illusion. Choice is a process that unfolds over time; it can be broken into sub-choices and revisions. Whether decisions are determined or involve ontic randomness does not by itself answer whether they were genuinely yours. If you deliberated, weighed reasons, and acted from those deliberations, we rightly treat that as agency. Randomness doesn’t create agency; reasons and responsiveness do.
We seem to be on the same page.


In practice, decoherence + dissipation + coarse-graining mean most quantum perturbations don’t make detectable macroscopic differences.
I'd even argue that none of them make detectable macroscopic differences. I mean, I measure an atom decay. Great, but I don't have a not-decay state to compare it with, so there's no 'difference'. I can imagine that other state since it is pretty simple, but I cannot imagine the evolution of that real and imagined state into a future state of a planet a year hence.


Quoting LuckyR
Yes, I know it isn't a true illusion. I said it's a "functional illusion", meaning that since the chocolate conclusion was set at the Big Bang (as you noted)
See just above, where only DBB suggests that chocolate choice was set at the big bang. DBB should stand for 'Da Big Bang'. Chicago folks would like that.

Thus while we all agree pondering occurs, as I mentioned, folks disagree whether both sides of the internal argument can result in chocolate or vanilla on one hand or always chocolate on the other.
I think it's all in how you frame the telling of the story. Proponents of 'vanilla being possibly chosen' would frame the story in such terms. Yea, you could have picked that, but you didn't, didja? If you had, you'd still ponder if you could have chosen chocolate.

A distinction without importance since in reality there is no practical difference.
Yes, and deal with the consequences. It's pretty easy to falsify the 'not responsible' stance since if one wasn't to be held responsible, different choices would be made. That means responsibility serves a purpose regardless of your stance.

It's a lot more precise than how you make it out. Imagine, the assassin sights the target. The window of opportunity is short, and the decision must be made quickly because the target moves on. So as much as the option remains, even after deciding not to pull the trigger, it would all have to be recalculated, and in reality would be a different option.

Consider firing a rocket to the moon. Everything is calculated to the exact liftoff time, and there's a small window. If there is a problem and the window is missed, everything has to be refigured. In general, and in words, it's refigured as the same option, "firing a rocket to the moon", but since it's refigured under different circumstances, it's not really the same option, just the same type of action under different conditions.

I think there is reverse psychology which comes into play here. So long as one does not pull the trigger, we can always consider doing so at a later time. But once the trigger is pulled that cannot be reversed. So, the psychology is that it is universally better not to act unless one is quite certain of success. The rocket cannot be retrieved after it's fired, so be sure of success before firing. However, if it is not fired, there will be many opportunities of the same type, therefore hold on until you're sure.

Your son got the punishment of reverse psychology. You pushed him toward failure, by inciting him to pull the trigger on something other than the best situation. Then he was embarrassed by jumping the gun, rather than patiently waiting, having to spit it out. That's why patience is a virtue.

How could there ever be only one path open? The future is always full of possibilities. And by being patient and not pulling the trigger we allow the possibilities to persist. But even falsely pulling the trigger only results in some kind of embarrassment. So if you pull the trigger and you're on the road to the softserve shop when the power goes out, you can turn around and go somewhere else. And even after the assassin fires the shot, he could fire another and another.

I believe the lesson is, that when you make the act, you put things in motion which inevitably restrict your future acts, unless your act is designed to increase your freedom, and it is successful. So the first principle is that nonaction maintains freedom. The second principle is that you might act in a way which would increase your freedom, but you need to be certain, because failure will backfire and lessen it.

Reply to noAxioms Thank you for the thoughtful engagement - I think we’re converging on several points while framing them differently.

On Claim A, I accept that Norton’s Dome demonstrates classical indeterminism under non-Lipschitz conditions, though it’s a purely mathematical curiosity. In any physically realizable system governed by continuous differentiable dynamics, each decoherence event still alters the global quantum state. Even if that alteration remains thermodynamically undetectable within a local Lyapunov horizon, it nevertheless yields a distinct universal configuration in principle. My claim concerns this ontological divergence, not its empirical detectability.

On Claim B, you’re right that the assertion depends on whether one accepts counterfactual definiteness. I was speaking from an Everett-style, decoherence-based ontology where every event contributes to a definite branch of the universal wave function. Under that framework, an event that leaves no macroscopic trace still differentiates the overall state of the universe. The difference need not be observable to be real.

For Claim C, I’d refine “always matters” as follows: every quantum perturbation modifies the total wave function, but only some of those perturbations are amplified within our causal region into new classical structures. Others disperse or remain dynamically isolated, but they still shape the global state. “Trapped” and “amplified” are perspectival distinctions within one continuous evolution.

On determinism and responsibility, I think we share the pragmatic view. Determinism doesn’t abolish agency; it merely redefines it as a complex causal process rather than an uncaused power. Responsibility survives as a social and ethical convention that regulates behaviour within the deterministic flow. To borrow my own GENE model language, deliberation and choice are emergent computations of Genes, Environments, Nutrients, and Experiences - not exemptions from causality but expressions of it.

So when I speak of “choice” or “agency,” I mean the real-time process of deliberation that precedes action, not a metaphysical ability to have done otherwise. The phenomenology of choice remains intact, even if the universe’s total state never could have evolved differently.

Everett interpretation does not hold to CFD, so unmeasured events effectively are not part of any specific worlds (they're not 'real': scientific definition). This is all part of the recent proof that the universe is not locally real. It can be local or real (or neither), but not both. Everett's is local. CFD is an assertion of real states, independent of measurement.

For Claim C, I’d refine “always matters” as follows: every quantum perturbation modifies the total wave function, but only some of those perturbations are amplified within our causal region into new classical structures.
We apparently are not going to agree on this point.

The phenomenology of choice remains intact, even if the universe’s total state never could have evolved differently.
We agree on the responsibility point. Of note: Under Everett again, the universe can and does evolve in all possible outcomes, which includes choosing differently, not choosing at all, and of course not even existing to choose.

Sure, one can spin a drawn out choice (to go to the moon, good example) as a series of more immediate choices that have temporal windows. The choice ends when there's somebody on the moon, at which point it's hard to change your mind about doing so anymore.

So, the psychology is that it is universally better not to act unless one is quite certain of success.
That works in some situations, but a not in a fair percentage of them. Such uncertainty prevents some people from ever getting married. Sometimes this is a good thing, but often not. Don't choose poorly, but also don't reject good choices for fear of lack of 'success'.
War is another example where that psychology is a losing one. Risk taking is part of how things are best done.

He did? He got crab legs and loved it. He also liked the other food he was eating, so at no point was he 'punished'.

Since I'm quoting movies, I remember Gandalf saying "now there is but one choice" once the entrance to Moria collapsed after they had entered. Go forth into the mine was the only option remaining. They hadn't the resources to dig their way out.

I believe the lesson is, that when you make the act, you put things in motion which inevitably restrict your future acts, unless your act is designed to increase your freedom, and it is successful.
Similar to a game of Chess or Reversi. Any move restricts possible future positions to those which follow from the new current state. In Reversi in particular, playing to maximize your freedom and minimize the opponent's freedom is definitely a winning strategy. Took me 8 years to figure that out.

So the first principle is that nonaction maintains freedom.

Look what you are saying. It can just be turned around. Not getting married was the mistaken choice which shouldn't have been made. Rejecting good choices is making a poor choice. So it's just a matter of what descriptive words are used.

Risk is never the best option. It is often unavoidable, but then the best option is the one which reduces the risk. See it's just a matter of wording. And the reason why it's confusing is because we are leaving out a key aspect. Success is in relation to a goal. So "unavoidable" is determined in relation to the goal. Once we frame things as being in relation to a goal, the whole perspective is variable, depending on the goal.

I don't agree with this. "Looking for food" implies a restriction that the person is looking for something which is known to be food. This restricts the person from eating all sorts of things which may actually be good food, yet not known to be "food" to the person.

The point being that action requires choice, and choice restricts the person's freedom to select all the other possibilities. If a hamburger is the only thing the person knows to be food, then "looking for food" is a significant restriction.

Look back at the moon example. "Going to the moon" required all those choices, and each one excluded all the other possibilities. Therefore there was a whole lot of other things which could have been done in that time, with those resources, but "going to the moon" was the chosen goal, and this negated all those other possibilities.

Truth Seeker October 20, 2025 at 15:26 #1019905
Reply to noAxioms Thank you for the thoughtful clarification. I think our main divergence lies in how we treat ontic status within the Everett framework.

You’re right that Everett dispenses with counterfactual definiteness: only the total wave function is “real,” while definite outcomes are branch-relative. However, if every decoherence event differentiates the universal state vector, then by definition, each “unmeasured” quantum fluctuation still contributes to the branching structure of the multiverse. The fact that we only observe a subset of classical branches doesn’t mean the rest lack existence; it only means they are decohered beyond causal contact with us.

So when I say “an event that leaves no macroscopic trace still differentiates the overall state,” I mean that decoherence is ontologically generative - the universe’s global wave function encodes every microscopic difference, even those never amplified to our classical level. From that global perspective, nothing “fails to happen”; it merely fails to be observable within our branch.

As for responsibility, I agree that phenomenology remains intact. Even if the total state-space evolves deterministically, subjective deliberation and outcome differentiation are still structurally real within each branch - enough to preserve the experiential grammar of choice, if not libertarian freedom.

The terminology grates with me, but more or less I agree. The universal state vector cannot differentiate since there is but only one of them, so it evolves over time, just like the universal wave function. It doesn't collapse, which I think would constitute 'differentiation'.

The fact that we only observe a subset of classical branches doesn’t mean the rest lack existence
Everett does not suggest separate 'branches' that have any kind of defined state. Such would be a counterfactual. So yea, Everett says that the universal wave function 'exists', period. It's a realist position, and it is that realism that is my primary beef with the view since it doesn't seem justified.

As for my opinion of Libertarian free will, that's just a term describing external agency, with no demonstration of any greater freedom than internal agency. Coming down with Rabies is an example of Libertarian free will. The agency is suddenly something other than yours, and Rabies (the external agent) now has the free will instead of you, and it compels you to bite people, and then Rabies becomes responsible for those assaults, not you.

I think this is a false example. The option is usually whether or not to marry a specific person, not whether or not to get married in general. And, if you're not certain about the person, you're probably not in love, and you should not go ahead at that time. And if the question is whether or not to get married in general, you should not go ahead with that, until you are certain that it is the right thing.

The difference between the way you and I are looking at this, is that you are making some kind of 'objective' statement "getting married is a risk", and from that you are saying that risk is good. But from that 'objective' perspective, every choice is a risk, so of course risk must be good or else all choices would be bad. But that's not what I am talking about. I am talking about looking from the perspective of the person making the choice. And from that perspective, if the act is risky it's better for the person to wait until they have more confidence. Often the stakes are very low, and risk is simply not taken into consideration. But as the stakes get higher, considering the risk gets more and more important.

Sorry, I didn't make myself clear. I should have said freedom to select from all the other possibilities. So for example if there is twenty options, then the person has the freedom to select from twenty options. However, once the choice is made you restrict your freedom to select the other nineteen. That's what I meant, making a choice restricts your freedom. If you have the freedom to choose X or not X, then choosing X restricts your freedom to choose not X.

Reply to noAxioms Thank you for your thoughtful and detailed reply. I appreciate your clarifications - especially on terminology.

When I said the universal state vector differentiates, I didn’t mean that it “splits” or collapses in any literal sense. I agree that the universal wave function evolves unitarily. What I meant is that decoherence continuously factorizes the total state into dynamically autonomous subspaces. The evolution is singular, but its structure becomes increasingly partitioned as interference terms vanish. In that descriptive sense, decoherence is ontologically generative - it produces new relational structure within the universal state, even if not new “worlds” as discrete entities.

You’re right that Everett himself didn’t speak of sharply defined “branches,” and I share your caution about reifying them. Still, decoherence does create stable quasi-classical sectors whose internal histories no longer interfere. Calling them “branches” is shorthand for these dynamically independent histories. So when I said that “an event that leaves no macroscopic trace still differentiates the overall state,” I meant that every quantum fluctuation alters the total wave function’s structure, even if those alterations remain forever unamplified from our classical perspective.

I also agree that quantum mechanics is not observer-dependent in the Wigner sense - nothing special happens because a conscious agent looks. My use of “observer” was relational, not Cartesian: any subsystem that records or correlates information functions as an “observer” relative to another. Within that relational framework, phenomenological perspectives arise naturally from entanglement structure, not metaphysical privilege.

Regarding freedom and responsibility: yes, phenomenology remains intact. Even if the total evolution is deterministic, each branch still contains agents whose deliberative architectures causally mediate outcomes within that branch. That structure grounds a compatibilist sense of agency: one can be determined and yet meaningfully responsible insofar as choices flow from one’s own evaluative processes. Libertarian freedom, by contrast, would require causal independence from one’s own nature - an incoherent notion. In your rabies analogy, the external pathogen literally overrides the person’s cognitive structure, which is why we no longer ascribe responsibility. The contrast actually illustrates compatibilism rather than libertarianism.

Stepping back, the parallel between branching and agency seems telling: both involve emergent autonomy within an underlying deterministic totality. The global state’s evolution may be seamless, yet locally it yields distinct, causally closed structures - worlds in one case, deliberating agents in the other. In both, the differentiation is real enough to sustain the lived grammar of choice, even if metaphysical freedom never enters the picture.

In my own framework - the GENE Causal Self Model - I interpret such autonomy through the interplay of Genes, Environments, Nutrients, and Experiences. Each agent’s decisions are determined by the evolving configuration of these factors, yet within that causal web, reflective self-organization still emerges. Much like decoherent branches of the wave function, selves are dynamically distinct yet law-governed substructures of a single evolving whole.

Careful. It factorizes the measured state into dynamically autonomous subspaces. That means that only the systems that have measured the decohered state become entangled with it, thus becoming 'factorized' along with it. There's no universe with a dead cat in it and another with a live one. There's just the unopened box and (relative to the lab) a cat in superposition of these states. The box prevents the 'split' from decohering any further.

This is a hypothetical example. Preventing any measurement like that is essentially impossible. Sure, they've done it for barely visible objects under conditions that would kill any lifeform, and only for nanoseconds, but Schrodinger's box has actually been done. They used a tuning fork instead of a cat.

You’re right that Everett himself didn’t speak of sharply defined “branches,”

Yea, it was DeWitt who first did that, and then backed off somewhat from that description.

My use of “observer” was relational, not Cartesian
Fine. Just making sure. I tend to use the term 'measurement' instead of 'observation', but even that term has overtones of say intent. 'Interaction'?
Within that relational framework, phenomenological perspectives arise naturally from entanglement structure, not metaphysical privilege.

Libertarian freedom, by contrast, would require causal independence from one’s own nature
I wouldn't say that since 'one's own nature' becomes this 2nd metaphysical causal process, and thus not intedependence of one's own nature. Independence of one's physical nature perhaps, but is there even a physical nature if that kind of thing is how it all works?

- an incoherent notion. In your rabies analogy, the external pathogen literally overrides the person’s cognitive structure, which is why we no longer ascribe responsibility.
Isn't that exactly what the dualists suggest is going on? Of course, a dualist with rabies would have the physical effected, and somehow the mental component also affected, at least rendered less efficacious. Tri-ism? Three agents (physical, mental, and pathogen) all fighting for control.

I actually do report a form of it. I am occasionally afflicted with a form of epiphenomenalism where I am awake but cut off from most physical causality. I wake up from this condition, and only with an extreme mental effort can I push through my will an move something (preferably turn my head). It's called sleep paralysis, and the short of it is that your motor functions turn off when you sleep. If this mechanism is faulty, you sleepwalk. If it fails to turn on the juice when you wake up, it's sleep paralysis. I guess I don't have to worry too much about ever sleep walking.

Stepping back, the parallel between branching and agency seems telling: both involve emergent autonomy within an underlying deterministic totality. The global state’s evolution may be seamless, yet locally it yields distinct, causally closed structures - worlds in one case, deliberating agents in the other.
Agree up to here.

In both, the differentiation is real enough to sustain the lived grammar of choice, even if metaphysical freedom never enters the picture.
I don't think human choice has anything to do with differentiation since under any other interpretation where there isn't the kind of differentiation you get under MWI, the exact same choices and responsibility results. The only difference is that there are not other worlds split of sufficiently long ago that those tiny difference have grown into macroscopic difference large enough to cause different choices to be made, and my choice and responsibility has nothing to do with what those other versions are choosing.

I think this is a false example. The option is usually whether or not to marry a specific person, not whether or not to get married in general.
I'm not talking about a choice to not get married. I'm talking about making a choice to commit to marriage now (propose, or accept a proposal), coupled with the subsequent actual getting married, which is the trigger being pulled: can't hypothetically undo that. Doing so would be presumably to one person.
Deciding to get married in general (with perhaps no specific prospect currently in mind) is not like pulling the trigger since one can always change one's mind about such a decision.

you should not go ahead with that, until you are certain that it is the right thing.
Few, arguably none, are ever certain of it being the correct choice. Plenty of people have attested to be certain about it, only to regret the decision later on. I'm lucky. Married over 40 years now. All my siblings are on spouse #2. The one that waited the longest to be 'most certain' ended in cheating (both parties) and divorce.

The difference between the way you and I are looking at this, is that you are making some kind of 'objective' statement "getting married is a risk", and from that you are saying that risk is good.
There's overtones of 'marriage is good' there, which I don't agree is always true. But each statement in isolation, yes I'm saying that. I have better examples of 'risk is good'. Marriage is my example of a decision of a trigger pull, something you can't undo.

I am talking about looking from the perspective of the person making the choice. And from that perspective, if the act is risky it's better for the person to wait until they have more confidence.
Disagree, for reasons and examples I've already posted. There are times when risk is high, but would likely get higher with time, and so confidence is likely to drop if you wait.
Take saving people from a burning building. You can risk your life and charge in there and grab the baby, or you can wait until the fire trucks get the fire more under control so your safety is more assured. That's a hard decision, and there are cases where each option is the best one.

So for example if there is twenty options, then the person has the freedom to select from twenty options.
Great. Agree. There are those that say that 19 of those options are not available for selection because it is the 20th you want, even if the other 19 are close contenders.

However, once the choice is made you restrict your freedom to select the other nineteen.
Under a pull-trigger sort of situation, yes. In other cases, one can change one's mind. We've been getting into the nitty-gritty about this latter case: "Was a decision really made if the option to change your mind is still open?".
The former restricts one's freedom. The latter does as well, but not nearly as much.

If you have the freedom to choose X or not X, then choosing X restricts your freedom to choose not X. Making a choice always restricts one's freedom.
Sometimes, per the above.

Anyway, I stand more clarified about your statement of making a choice curtailing freedom.

Reply to noAxioms Thank you for your detailed reply. I think we’re largely aligned, though we diverge on a few interpretive nuances.

On factorization, I accept your refinement: decoherence doesn’t magically bifurcate the universal state into sealed compartments but rather entangles subsystems such that coherence between them becomes practically lost. When I said “continuously factorizes the total state,” I meant this relational entanglement structure - the effective tensor-product decomposition that yields dynamically autonomous components relative to the measurement context. So yes, the split is local and conditional, not global. I like your phrasing that “only the systems that have measured the decohered state become entangled with it.” That’s a good corrective to the loose Everettian imagery.

I share your relational preference over full-blown realism. My “ontologically generative” phrasing was intended in that same spirit: the ontology is not a collection of separate universes but a web of ever-evolving relational configurations. The structure of relations changes - new entanglement correlations come into being - even though the global amplitude distribution remains one evolving unity. So perhaps “structurally generative” would be the better expression.

Regarding “observer” versus “interaction,” I agree completely. I used “observer” phenomenologically, but “interaction” avoids the mentalistic overtones. I’m wary of language that suggests intent or consciousness as a special causal category; it risks re-smuggling the old metaphysical privilege that quantum theory works so hard to dissolve.

On free will, I think we converge on compatibilism but may use slightly different vocabularies. I take your point that “one’s own nature” could itself be construed as a second metaphysical causal chain, but I meant it more modestly: the organism’s integrated causal structure - its neural and psychological architecture - as distinct from an external intruder like the rabies virus. The point is not that one becomes “independent” of causality, but that causal efficacy remains internal to the system’s evaluative dynamics. That’s why the rabies example marks the boundary between responsibility and compulsion. Dualists, as you say, would complicate that further, perhaps imagining the pathogen interfering with both the physical and the mental “tracks,” but I see that as multiplying mysteries rather than explaining anything.

Your description of sleep paralysis is fascinating - it’s a vivid phenomenological example of partial causal decoupling: consciousness active, motor output suppressed. From a naturalistic angle, it actually illustrates how finely tuned the causal layers of agency are: when one channel is interrupted, agency becomes experiential but not performative. It’s a transient epiphenomenal pocket, not a metaphysical clue, but I can see why it feels uncanny.

As for your final point - that human choice doesn’t depend on branching - I fully agree. The experiential grammar of choice would be the same in any interpretation, whether Everettian, Bohmian, or GRW. My comparison between branching and agency was metaphorical: both involve local differentiation within a globally deterministic process. The analogy isn’t meant to make agency depend on branching, only to highlight the structural parallel between emergent autonomy in physics and in psychology.

In that sense, I see compatibilist freedom and relational quantum ontology as reflections of the same deeper pattern: causal closure at the global level, emergent quasi-autonomy at the local. In my GENE Causal Self Model, those quasi-autonomous patterns are constituted by the interaction of Genes, Environments, Nutrients, and Experiences - a biological analogue to decoherence’s relational structure. Both describe complex systems that remain causally determined yet exhibit self-organizing agency through internal feedback loops. Determinism and autonomy, far from being opposites, are two perspectives on the same relational process.

I admit, I could never frame "risk" with a definition which would make it universally bad. But in thinking about it I see that there is quite a number of different ways to relate to risk. There is risk of failure. There is risk that even with success in obtaining the goal, it wasn't the best goal. There is also risk that proceeding toward one goal will produce failure relative to another. So many different types of risk.
