A Lenient Causal Arrow of Time?

Understand

One of the basic assumptions underlying Bell's theorem is the causal arrow of time, having to do with temporal order rather than spatial separation.

• Nonetheless, the physical assumptions regarding causality are seldom studied in this context, and often even go unmentioned, in stark contrast with the many different possible locality conditions which have been studied and elaborated.
• In the present work, some retrocausal toy-models which reproduce the predictions of Quantum Mechanics for Bell-type correlations are reviewed.
• It is pointed out that a certain toy-model which is ostensibly superdeterministic -- based on denying the free-variable status of some of Quantum Mechanics' input parameters -- actually contains within it a complete retrocausal toy-model.
