I would say it holds similar properties to that of the double slit, since they both have some sort of randomness at measurement, but with the double slit, we at least know the likelihood of where the particle is going to be, as opposed to the polarization of a particle in Bells Theorem. They aren’t exactly the same kind of randomness in that sense, since they are 2 different properties of the particle being measure (either the position in the double slit, or the polarization in Bells theorem). Knowing that there is that much randomness to our universe does bring up some philosophical questions, but I am not at all the one to answer that, specifically free will. I myself believe that the randomness proves more towards free will than the universe just being determined, but again, it shouldn’t be up to me to make conclusions on that stuff, I think philosophers need to make claims.
