@Dianora There is no need for pilot wave theory. Particles behave fully classically. The probabilities are simply those of the experimental arrangement.
I have written many simulations that show this is so for the Bell experiment.
But I have also discovered simple arguments that show there CANNOT be such a thing as "quantum" behavior distinct from classical. You can, for example, easily re-craft the Bell test as a COMPLETELY EQUIVALENT experiment ABOUT COOKIE BOXES.
