I’ve personally accepted that it’s basically predictable/deterministic, but due to how complicated and unknowable the system is there’s no practical way for an outside observer to get all the information.
I’m guessing the lower resolution imaging methods might still allow more or less accurate prediction, though? We don’t need to know the details on every air molecule to do fairly accurate weather forecasting, so maybe the same approach can work to predict mindweather. Maybe it’s possible to know a person’s brain well enough and accurately adjust predictions very fast after random encounters/events influencing them – like the people they meet, the things they see, and a myriad of other things – and in that way get something more and more capable of predicting behavior?
I don’t really know much about either field, though.
Even if you had perfect knowledge of the current state of the universe, knew all the laws, you still couldn’t predict shit. The reason is chaos, more precisely: There are no closed-form solutions to chaotic systems. To simulate them you have to go through all the time steps (assuming, without loss of generality1, discrete time), simulate every single of them one after the other, arguably creating a universe while doing so. And you have to do that with the computational resources of the universe you’re trying to simulate. Good luck. Chaos also means that approximate solutions won’t help because sensitivity to small perturbations: There’s no upper bound to how far your approximation will be off.
1 I can wave my hands faster than you. I dare you. I double-dare you.
