As said in post #1, Barandes admitted that he attributed a bit much of Reichenbachianism to Bell in that paper (see later podcasts). Bell seems to have drifted from that or at least Bell seems to have different definitions not all fully Reichenbachian.Morbert said:Barandes argues that Bell's principle of local causality relies on a definition of common cause that is too narrow. Specifically, Bell's principle of local causality assumes common causes must take the form of "Reichenbachian variables". E.g. If two variables A and B are correlated, but not exerting influence on one another, then there must be variables λ that exert a common causal influence on A and B.
Barandes argues there can be non-Reichenbachian common causes that establish the correlations seen in entanglement, like local interactions at a previous time, that Bell's principle miss as they do not take the form of λ, and hence you can have causally local theories that violate Bell's principle of local causality.
