Expected rates of false positives (light grey) and false negatives (black) for groups that consist of Condorcet juries or of various combinations of PLUS- and MINUS-animals (i.e. ratios of 0 : 1, 1 : 3, 1 : 1, 3 : 1 and 1 : 0 PLUS : MINUS-animals, respectively). The probability p(k) (that option PLUS is the correct choice in the kth environmental situation) follows a asymmetric bimodal distribution with a high variance and a base rate of B = 0.55 (to save space, results for low variance are not shown but are qualitatively similar). Note, same as figure 2 legend.
