Abstract

In general, the CHSH inequality S le 2 is considered to provide an upper bound for classical correlations. In this note it is shown that if incoming particles are allowed to be delayed ever so briefly, the inequality can be inverted to S ge 2 thus becoming a lower bound for classical correlations maximum S=3. All interaction is strictly local and events are neither dropped nor re-sequenced thus strictly conforming to the standard CHSH setup. The key notion is that a (brief) delay in front of a detector is not a causative intervention.
