Individual and group phase in each trial. In the individual phase, each participant viewed different stimulus sequences consisting of 11–13 disks. Based on these sequences, individuals decided whether their sequence has more likely been produced by a fair coin (50% red, 50% blue) or a biased coin (60% red, 40% blue). Based on the ambiguity of the sequence, individuals reported a confidence in their own decision. In the group phase, participants combined their evidence into one group decision and confidence. In each trial, participants were incentivized for accurately judging their real group confidence using the matching probability method by Massoni et al. (2014)
