> We could assume that they were always that way from when they were conceived Nope. Bell Inequality: a more complex lab experiment shows that they don't hold their state, they were not "that way" before measurement. That's the reason behind the rants about spooky action at a distance, superdeterminism, MWI, etc. Before someone starts yelling "You can't prove that, you can't peek the quantum states, you cheater!" I'd like to point out that it's reality showing its weird face and no human-made proofs were in use.
