On Bell-Like Inequalities for Testing Local Realism

TL;DR

This paper defends the validity of Bell-like inequalities, especially the CH inequality, as proper tools for testing local realism, establishing a solid methodological foundation for analyzing related experiments.

Contribution

It clarifies the correct application of the CH inequality and counters objections, providing a rigorous basis for future experimental analysis of locality.

Findings

Objections to inequalities are invalid

CH inequality can validly test locality when applied correctly

Provides methodological foundation for analyzing CH experiments

Abstract

Objections to the use of inequalities to address foundational issues are considered and shown to be invalid. The Clauser-Horne (CH) inequality is considered and interpreted in this light. It is shown that, applied correctly, the CH inequality can validly test aspects of locality. This paper establishes a firm methodological ground for a following paper analyzing a recent CH experiment.
