Bell’s Notion of Local Causality

Abstract

At the beginning of this Chapter Bell’s different formulations of local causality will be reviewed. Next, we analyze the three key concepts featuring in Bell’s final formulation, namely “local beables”, “shielder-off region”, and “complete specification.” We translate them into the LPT framework and provide a generalized definition of local causality. Finally, we relate shielder-off regions to d-separating sets in a Bayesian network and prove that local primitive causality renders an atomic LPT to be locally causal.
