Title: Bell Correlations via Constrained Colliders -- a Path from W to V

Abstract: In previous work with Ken Wharton, I have proposed that Bell correlations are a special sort of selection artefact, explained by a combination of (i) collider bias and (ii) a boundary constraint on the collider variable. This hypothesis requires no direct causal influence outside lightcones, and may hence offer a new way to reconcile Bell nonlocality and relativity. This piece outlines a new argument for the proposal. It explains how it is valid for a special class of (W-shaped) Bell experiments involving delayed-choice entanglement swapping, and argues that it can be extended to the general (V-shaped) case.
