Measurement independence, parameter independence and non-locality

Abstract

In a recent paper in this Journal San Pedro (2012) I formulated a conjecture relating Measurement Independence and Parameter Independence, in the context of common cause explanations of EPR correlations. My conjecture suggested that a violation of Measurement Independence would entail a violation of Parameter Independence as well. Leszek Wronski ( ´ 2014) has shown that conjecture to be false. In this note, I review Wronski’s arguments and agree with him on the fate of the con- ´ jecture. I argue that what is interesting about the conjecture, however, is not whether it is true or false in itself, but the reasons for the actual verdict, and their implications regarding locality
