Comparing ideal versus reported confidences from individuals and groups. Ideal confidence (x-axis) ranges from 50 to 100% in accordance with Table 1. In contrast, reported confidences (y-axis) range from 0 to 100% because we flipped confidence ratings in cases where an incorrect decision was given (e.g., a reported confidence of 60% toward the incorrect decision is displayed as a confidence of 40% here). In a, reported confidences from individuals (y-axis) are compared to the ideal values (x-axis; cf. \(c_1^*\), \(c_2^*\), and \(c_3^*\) from Table 1). Similarly in b, reported confidences from groups (y-axis) are compared to the ideal values (x-axis; cf. \(c_g^*\) from Table 1). Black points indicate mean values—averaged across individuals in a and across groups in b—for each ideal value. Grey points indicate single trial responses. Error bars indicate standard errors of the mean
