Sean Carrol: In my mind, and in all right-thinking people's minds, there is no connection between free will and determinism #FQXi2019
(I wonder how you can exert free will in a nondeterministic universe.)

My comment was about language, and about how we talk about these things. My point is that often the ability (or perception of being able to) to predict behaviour is presented as a proof of something being deterministic.

I think it's wrong to say that indeterminsm implies unpredictability even on a strict scientific level. Let's take a function that is random for x above 100, and y = 3x for x <= 100. Is it unpredictable? Maybe but if my input is always < then it is predictable.
-
So then part of that function is deterministic and part of it is random. As far as I can tell you can always at least theoretically reduce these functions down to a deterministic and a random part.

Another point is precision. Let's take a f = random(0,1). I can predict that it's output is between [0 and 1). I can predict that after some throws more less 50% of results will be between 0 and 0.5.
-
Of course statistical predictability is always possible, but I don't see how that would be relevant. Randomness can still be defined as "lack of predictability", no matter if it can be approximated over a large number of events or not. Same goes for indeterminism.

Btw. I'm sorry for spamming. Twitting presents some challenges when it comes to debating :)

Finally, I'd say that when we talk about determinism for humans then being deterministic means giving the same output no matter what the inputs are. I'm talking about destiny, grit, as in "He cycles no matter what the weather is". I'm not saying this is correct.
-
"Same output no matter the input" would mean that the human would only give one output repeatedly for it's entire lifespan. That's.... a bit strange. So more like "He cycles every second of his life no matter what happens around him".
