If there are people who can’t picture and people who don’t have an inner dialogue, I think it lends more credence to the idea that we don’t have free will and are just a bunch of chemicals controlling our behavior. It also makes you think about consciousness and whether it’s even real.
You think "I will wash the dishes". You wash the dishes. Ta-daa, free will!
A paralyzed person thinks "I will raise my hand". Nothing happens. No free will!
An ADHD person says to themself "I will wash the dishes". They don't get washed. A different part is broken than to the paralyzed person, but the result is the same.
A lazy person says to their roommate "I refuse to wash the dishes". Free will? They "could", if they were not lazy. Just as the ADHD person "could" if they did not have executive dysfunction. Just as the paralyzed person "could" if their spinal cord were intact.
"Free will", as a philosophical construct, is nothing more than an attempt by the ego to regain a sense of control in the face of the irrefutable realization that the universe is governed by rigid laws, and we are made of universe. (And no, quantum randomness doesn't help you - a random choice is hardly more of an extension of will than a deterministic one).
Firstly, a person suffering from ADHD can do the dishes, despite the odds being against them. And a paralyzed person can raise their hand, given advances in technology.
And these are bad examples, as being incapacitated isn't an argument against free-will. The paralyzed still wants to raise their hand, even if they are unable at the moment. And the far more difficult question is if that want was entirely predetermined by the universe or not.
Quantum randomness and the huge number of variables at play point to the fact that believing that we don't have free-will is a non-falsifiable notion.
Consider this thought experiment: God comes to you and says ... "Here are 2 universes you can observe, one in which people have free-will, and another, that looks similar, but its people are just sophisticated automatons. Make an experiment to say which is which."
Your irrefutable argument quickly falls apart because there's no way you can show any relevant evidence for it. And it's worse than talking about the absence of God, because we experience free-will everyday. It's like talking of consciousness — we can't define it yet, but we know it's real, as we're thinking and talking about it. And a theory being non-falsifiable does not make it false. God could exist and you could have a soul.
You may or may not believe in free-will. But not believing in free-will is dangerous because it makes one believe that everything is predestined, so there's no point to doing anything, no point in struggling to achieve anything, no point in trying to escape your condition. If no free-will is possible, does life have any value at all? And that's the actual philosophical bullshit.
