The derivation of Bell inequalities requires an assumption of measurementindependence, related to the amount of free will experimenters have in choosingmeasurement settings. Violation of these inequalities by singlet statecorrelations, as has been experimentally observed, brings this assumption intoquestion. A simple measure of the degree of measurement independence is definedfor correlation models, and it is shown that all spin correlations of a singletstate can be modeled via giving up a fraction of just 14% of measurementindependence. The underlying model is deterministic and no-signalling. It maythus be favourably compared with other underlying models of the singlet state,which require maximum indeterminism or maximum signalling. A localdeterministic model is also given that achieves the maximum possible violationof the well known Bell-CHSH inequality, at a cost of only 1/3 of measurementindependence.
