Why free will is a smart bet
I like this Jordan Peterson criticism of free will determinism. A fundamental problem in the discussion is whether the neuroimaging evidence is a proof against free will or not. He goes to some detail why this should not be at least automatically assumed to be the case, but even on the high level considering we have a very sketchy understanding of consciousness over all it seems hard to make causal statements about it's functioning. Just because free will is complex and strange and escapes our understanding does not make it impossible.
A more proper argument would be to make testable predictions, show the existence of the determinism by correctly predicting the outcome of some human choice. This would demonstrate that understanding of the mechanisms of choice and that we're more a passenger than the captain in them. And even this in individual cases would not be the end of free will. Like Jordan Peterson says, free will is not absolute. Most of the choices during most of our days like what to wear, eat, do with our free time happen "automatically" with little agency, but that's just the brain in power saving mode to save calories.
A proper test of free will are cases like quitting smoking we are conscious about the choice, it's important and we have a clear "will" about it. But even then it's hard and in many ways out of our control, you can decide to not smoke any single cigarette but still end up lighting one when you least expect it. Nicotine has spent years rerouting our synapsis making smoking the default option, the path of least resistance. But I'd say free will is not the moment of saying "I quit smoking" but in the moment of thinking "I hate that I smoke and would like to quit and start googling for options". Free will happens more in the domain of what values we hold true, faith, than than individual acts.
And even if you are not convinced of these, I like the thought you're better off acting like it would be. In the end this is probably (at least for now) a matter of faith, something you need to decide whether to hold as true or not. And I'd say life is better if you have free will. And as long as you can't tell the difference from not having it, you might as well enjoy the benefits :) https://www.youtube.com/watch?v=uC6BPg7IDpA
