Illustration of the behavioral task. At the start of each block,
participants were told which of three hidden agents can intervene
(a): the bandit (adversarial condition), the tycoon (benevolent
condition), or the sheriff (neutral condition). Participants then
chose between two different-colored mines (b, left). After receiving
feedback, participants answered whether or not they believed that
the hidden agent intervened on that trial (b, right).
