Bell Correlations and Selection Bias
Huw Price
Methods of selecting samples from larger populations may produce bias, in either direction: inducing correlations between variables independent in the full population, or masking c…
Bell Inequality Violations Without Entanglement? It's Just Postselection
Ken Wharton, Huw Price
Recently Wang et al. have reported a violation of a Bell inequality without entanglement [arXiv:2507.07756]. We show that their result is an artifact of postselection. It is well k…
Taming Entanglement
Huw Price, Ken Wharton
In statistics and causal modeling it is common for a selection process to induce correlations in a subset of an uncorrelated ensemble. We propose that EPR and Bell correlations are…
W as the Edge of a Wedge: Bell Correlations via Constrained Colliders
Huw Price
In previous work with Ken Wharton, it was proposed that Bell correlations are a special sort of selection artefact, explained by a combination of (i) collider bias and (ii) a bound…
A Mechanism for Entanglement?
Huw Price, Ken Wharton
We propose that quantum entanglement is a special sort of selection artefact, explicable as a combination of (i) collider bias and (ii) a boundary constraint on the collider variab…
