The derivation of Bell inequalities requires an assumption of measurement independence, related to the amount of free will experimenters have in choosing measurement settings. Violation of these inequalities by singlet state correlations brings this assumption into question. A simple measure of the degree of measurement independence is defined for correlation models, and it is shown that all spin correlations of a singlet state can be modeled via giving up just 14% of measurement independence…

The Significance of Measurement Independence for Bell Inequalities and Locality
A local and deterministic model of quantum correlations is always possible, as shown explicitly by Brans in 1988: one simply needs the physical systems being measured to have a suitable statistical
Optimal free will on one side in reproducing the singlet correlation
Bell’s theorem teaches us that there are quantum correlations that cannot be simulated by just shared randomness (local hidden variable). There are some recent results which simulate the singlet
Relaxed Bell inequalities and Kochen-Specker theorems
The combination of various physically plausible properties, such as no signaling, determinism, and experimental free will, is known to be incompatible with quantum correlations. Hence, these
Determination of hidden-variable models reproducing the spin singlet
The experimental violation of Bell inequality establishes necessary but not sufficient conditions that any theory must obey. Namely, a theory compatible with the experimental observations can satisfy
Local deterministic simulation of equatorial Von Neumann measurements on tripartite GHZ state
This paper provides a local deterministic model for equatorial Von Neumann measurements on tripartite GHZ state by sacrificing measurement independence partially, and shows that such correlation also hasLocal deterministic description if measurement independence is given up, even if not completely.
A simple model for the spin singlet: mathematical equivalence of non-locality, slave will and conspiracy
A hidden-variable model reproducing the quantum mechanical probabilities for a spin singlet is presented. The model violates only the hypothesis of independence of the distribution for the hidden
Lack of measurement independence can simulate quantum correlations even when signaling can not
In Bell scenario, any nonlocal correlation, shared between two spatially separated parties, can be modeled deterministically either by allowing communications between the two parties or by
Relaxed Bell inequalities with arbitrary measurement dependence for each observer
Modified Bell inequalities are derived that relax measurement independence, for either or both observers, while remaining locally causal, and it is argued that, contrary to various claims in the literature, relaxing freedom of choice need not imply superdeterminism.
One sided indeterminism alone is not a useful resource to simulate any nonlocal correlation
It is found that any amount of randomness in correlations of one party in absence of signaling between two parties is incapable of showing any sort of Bell–CHSH violation, whereas signaling and measurement dependence individually can simulate any nonlocal correlations.
How much measurement independence is needed to demonstrate nonlocality?
A connection is demonstrated between models that weaken the assumption that measurement settings are freely chosen by the observers, allowing partial correlation, and models that allow classical communication between the distant parties, including models that exploit the detection loophole.
