Abstract

Fine has recently proved the surprising result that satisfaction of the Bell inequality in a Clauser-Horne experiment implies the existence of joint probabilities for pairs of noncommuting observables in the experiment. In this paper we show that if probabilities are interpreted in the von Mises-Church sense of relative frequencies on random sequences, a proof of the Bell inequality is nonetheless possible in which such joint probabilities are assumed not to exist. We also argue that Fine's theorem and related results do not impugn the common view that local realists are committed to the Bell inequality.

Footnotes

Ken Regan made extremely useful suggestions related to the mathematical issues involved in the paper, and David Wood helped us see further implications of the inequality-conforming cases discussed in Section 2. We are very grateful also to Arthur Fine, Robert Weingard, Thomas Brody and Nancy Cartwright for comments on an earlier version. One of us (G. S.) thanks CNPq and FINEP, agencies of the Brazilian government, for financial support.
