Decision-making involves a probabilistic function with statistical noise, and after a choice is made, the brain forecasts the outcome and updates the system based on prediction accuracy.

“so uh it's you know it's a soft Max function as we say so it's not like a hard deterministic one so there's there's some statistical noise in there for some you know we could talk about what that reason might be you make a choice and whenever you make a choice in any any behavior that you're engaging in your brain is making a forecast of what's going to happen next as a result of that and your brain then uh determines computes did things go exactly as predicted right is it better than predicted or is it worse than predicted and then that signal gets fed back into the system to update it so that it hopefully performs that job better in the future right”
