No common cause model can fit the phenomena that violate Bell's Inequalities; what sorts of probability models could do so? To answer this, we need to broaden our concept of statistical or probability models, while not broadening it so much as to trivialize it. Introduced here are the distinctions between a surface (phenomenal) model and a theoretical model, and between the general class of geometric probability models and their subclass of quantum theoretical models, together with some elements of quantum logic, and the basic use of probability models to represent measurement situations.
