I doubt that. Free will doesn’t even make sense as a concept. If it’s true that there’s no such thing as a soul and that is almost certainly the case, the mind is just a series of physical systems obeying causality. Given this I doubt any legitimate scientists believe in nonsense like free will.

This proves it's not your conscious/cognitive brain parts making the decision. Since those are what correlates to your conscious experience, or what you call "you", or what is effectively "you" for all purposes, "you" do not have free will.
Something else inside your brain is making decisions for "you".

This experiment proves that quite beautifully, really. You could try to cope by saying "that unconscious part is still me, even if I'm not controlling it", but to me that would be like a car saying the driver is part of the car.

The first one has literally nothing to do with quantum effects.

The second one is a proposed model, not an empirical paper, and has been widely criticized.

Correlation causation fallacy

It's like looking at a software's behavior and trying to describe it in terms of computing technology

Of course software follows the laws of physics and has underlying behavior. However physics is not an adequate causal for the software's existence, and behavior in terms of the end user.

The satisfying and logical solution is not to describe software in terms of the underlying physics, but in terms of how it was designed and how it's being used.

In the same way, living organisms arise and evolves somewhat randomly from the physics, but once they are alive hunger and need satisfaction is not best described by the underlying physics, but by the psychological model of the animal

>> No.11679403

>>11679258
This is simply wrong. You can model whatever process you want at various analytical levels of description, and one level is not more correct that the other so long as the model makes testable predictions. Dynamical systems models make valid and non-trivial predictions, which is why they are used. People don't develop these models just for shits and giggles. You should have read the papers anon.

correlation causation fallacy is not wrong
alternative theories as you mention are not neccesarily more or less correct than each other

thus being hungry and eating because a near infinite number of math equations work out that way, and being hungry and eating because you decide to because you have self awareness and decision power aren't mutually exclusive. THere's tremendous value in understanding neurology, but there's no reason to throw out common sense (that will exists.)

>correlation causation fallacy is not wrong
While I agree that inferring causation from correlation is a fallacy, it is wrong in the sense that it has no relevance for the argument.

>common sense
The problem with that is is often used as an excuse to not properly define terms. Everyone has their own folk psychological notion of what constitutes freedom of will. Some see it as the ability to arbitrate between choice alternatives, others see it as conscious control over their desires. Whether it exists or not depends on what definition you adopt, and apppeal to common sense prevents clarity on the exact definition.

what i mean by correlation causation is that

X,Y,Z phenomena happen during the process of thinking
that doesn't necessarily imply X,Y,Z are the causes of thinking

I might be stretching the typical usage a bit.

>common sense
I would agree that the argument is very messy and causally throwing around overused concepts isn't too helpful.

However everyday observation throws us a lot of experimental evidence. There are apparent conscious, self aware beings who make decisions based on physical and mental states. Split hairs any which way, something resembling the rough concept of free will exists.

I am arguing against tossing out this evidence for no reason, and assuming the most basic physical laws as they are explain everything.

It's possible someone could find that all possible behaviors stem from pure math, but I won't be holding my breath.

>>11679849
mathematics is pretty harmonious with the nature of phenomena. It doesn't seem necessary to say that all phenomena is just an illusion because it has an underlying mathematical description,

besides that, even if we just assumed everything was mathematical in nature, you can't really exclude "yourself" from the initial conditions of your decisions, meaning you cannot skip over giving credit for decision making to"yourself" to the underlying math or physiology-it's equivalent to "you."

>It doesn't seem necessary to say that all phenomena is just an illusion because it has an underlying mathematical description,
I agree that only by virtue of the fact that there might be a mathematical description we should discard the phenomenon altogether and that this argument is often used on 4chan. But that is not the argument that I am making.

By the same token you could argue that just because you perceive it, it doesn't mean it has a basis in reality (i.e. 'exisis'). The majority of your precepts have no basis in physical reality. I don't think anyone denies that we perceive, and that out perceptions are real, but what's very much up for debate is whether our perceptions depart from the causal chain of events in nature (i.e. 'free').

This is not typically how people draw conclusions about the implementation of cognitive constructs. Your example overlooks the fact that if disrupting X,Y,Z, prevents thinking from taking place then you can in fact infer that X,Y,Z is casually responsible for the process of thinking.

We do things like that all the time, we call it "science." Software is written in a certain language, with rules, compiled into various layers of abstraction beneath, until it's eventually in machine languages and mapped on to logic gates. Why is this not "adequate." It's like saying we shouldn't do research into quantum physics, we should just stop at atoms, since that is easier to understand thus more "satisfying." What a dumb post.

I've wasted too much time writing this response so it's going to be shit, because i dont care enough to refine it

A useful method of modelling the world is using formal logic.
An oversimplified example is, if A, B, C ... Then D

You take several premises and reach a conclusion

It is possible for contradictory premises to lead to the same conclusions, for example:
- creationism and god lead to the world we see
- big bang/eternal cosmic inflation and evolution lead to the world we see

--

To answer your question about high IQ people believing in souls/god

believing (Y) or not believing (N) in a soul/god does not seem to allow us to derive conclusions that:
-differ between Y and N
-are mutually exclusive, ie only Y or only N has the correct conclusion
- are demonstrably and irrefutably and unquestionably true

There are "proofs" of the soul and/or god, but these tend to be flawed in that they make arbitrary choices regarding premises (as an example), such as descartes trademark argument

Regardless, the unprovability does not mean falsity

It seems high IQ individuals don't study philosophy sufficiently, or just stick with whatever belief system they were raised with or is most comfortable to them

>> No.11683120

>>11683020
I'm playing doubles advocate. I'm somewhat meme'ing. The fact is though, yes, we can model things using human observation, logic, and perception. Until we can make AI that can think outside of human thinking we are basically stuck with that. I'm pretty sure that super high iq individuals understand this and that's why a lot of their "theories" involve some sort of spiritual aspect. An unknown variable that acts on the "world" and the "world" acts on it. Arguing 100% both ways with all the unknowns is stupid. Our observations can definitely fit within the unknown, clearly what we observe with formal logic works on our scale. We can observe and manipulate, so it's possible that we can also be "observed" interacted with and manipulated.

Quantum mechanics have been posited and proven to be utilised in a number of biological creatures' metabolic, signalling, neural and perceptive processes including microtubules in humans, photosynthesis, the quatum structure of butterfly wings to manipulate photons below the wavelength of light, and magnetic sensing in birds. This last one has been challenged but the fact that biomagnets have been found inside the beaks of birds, I think that it is case closed.

Whenever, I hear people dispute the idea of quantum biological traits, I get the feeling that they are Darwinian Evolutionists, who percieve it as a threat to their worldview and therefore always react in a violent and/or unpleasant manner, towards the new information. This is just another example of how dogmatic evolutionists hold back scientific innovation and research.
