Iso-accuracy gradients (regions of the same color) show that multiple combinations of sensitivity and bias produce the same accuracy. For example, at moderate sensitivity (d′=2), both liberal bias (c=-0.5) and conservative bias (c=0.5) can produce accuracy near 0.8 in this simulated neutral-bias environment (parameter values provided in Supplemental Material).
