Figure 2: The bounds on the LG inequality for quantum mechanical and macrorealist models depend on the venality in the experiment.

Plots of the quantum mechanical prediction (white) and lower bound of a modified inequality for the a, moderate (blue) and b, adversarial (red) macrorealist attitudes as a function of the angle θ and the venality ζ. Where the quantum prediction dips below the macrorealist bound it is in principle possible to invalidate the macrorealist stance. Note the critical value of ζ=0.25 and ζ=0.1 above which one cannot exclude macrorealism for the moderate and adversarial approaches, respectively.
