From: Social signals of safety and risk confer utility and have asymmetric effects on observers' choices
Each trial started with a ‘New Round’ screen. Participants made a series of choices between two gambles, one of which was objectively riskier than the other. The decisions were made (a) alone ('Solo' trials) and also (b) with information provided about other players' selections ('Info' trials). At the start of each trial, a new pair of gambles was presented. For each pair, the safer ('safe') gamble had lower payoff variance, and the riskier ('risky') gamble had greater payoff variance (see Online Methods for full gamble details). On Info trials, two others' decisions were displayed prior to the participant’s cue to enter a choice. Info and Solo trials were intermixed with a new random order for each participant and drawn without replacement from a uniform distribution.
