A realistic view of the Einstein–Podolsky–Rosen–Bohm experiment with spins based on quantum theory is presented. This view implies that there is no action at a distance. It also implies that the measurement result A ( B ) for particle 1 (2) depends on both magnet angles, and hence the probability of obtaining the result A ( B ) also depends on both magnet angles. In the light of these realistic implications, it is clear that what is wrong at least with local realistic theory is not the locality or no-action-at-a-distance assumption itself but rather the formal implementation of that assumption.

Rebooting Einstein's ideas about local-causality, an engineer brings local-causality to quantum theory via operators and variables in 3-space. Taking realism to be the view that external reality exists and has definite properties, his core principle is common-sense local realism (CLR): the union of local-causality (no causal influence propagates superluminally) and physical-realism (some physical properties change interactively). Endorsing Einstein-separability — system X is independent of what is done with system Y that is spatially separated from X — Bell's famous mission is advanced. That is, by means of parameters λ, a more complete specification of EPRB's physics is successful. A consequent locally-causal refutation of Bell's theorem allows EPRB correlations to be explained in a classical way, in line with Einstein's ideas, without reference to Hilbert space, quantum states, etc. Conclusion: Bell's theorem is based on a mathematical error; an error in reduction is inconsistent with Bell's opening assumptions.

We propose a consistent local theory Th(g) extending the quantum formalism. As a consequence, a realistic and local (“common cause”) interpretation of the Einstein-Podolsky-Rosen-Bohm ideal experiment can now be given. The extended local theory Th(g) satisfies the Bell inequality τ. We call for an experiment to test the validity of τ∈Th(g) and submit it as a crucial test against the apparently false conjecture of nonlocality.
