Huw Price's selection-bias account of Bell-inequality violations reaches a similarly-shaped locality-preserving conclusion to Horvat's through an unrelated mechanism

Huw Price's "Retrieving the Baby: Reichenbach's Principle, Bell Locality, and Selection Bias" (arXiv:2602.16985, submitted 19 Feb 2026; also deposited on PhilSci-Archive) argues that the failure of Bell's "Factorizability" condition "may be regarded as a selection artefact, requiring no violation of locality in the intuitive, conceptual sense with which Bell begins his analysis." The diagnosis runs through Reichenbach's Principle of Common Cause and an analogy to selection bias in statistics (the "collider" effect) — not through history-dependence or a Markovian-versus-non-Markovian distinction.

The top-level conclusion rhymes with Sebastian Horvat's — Bell violations needn't indict locality — but the diagnosed culprit is entirely different: selection effects in Price, the falsity of "Irrelevance of History" in Horvat (see claim-horvat-probabilistic-locality-and-irrelevance-of-history-jointly-imply-bells-local-causality). The two are not independent tests of the same mechanism; they are competing candidate explanations for the same explanatory gap. Price's paper also predates Horvat's preprint by over eight months and cannot have been responding to it. Horvat's own paper cites Price's work as closely related recent work, not as a confirming result — see question-corroborate-horvat-probabilistic-locality-preprint-single-source.
