Fig 1. Three example screenshots representing what participants saw at different stages of the experiment.

The top screenshot is an example question from the language topic. Participants could either select one of the two blue buttons showing two possible answers (one correct, one incorrect), or select the red button labelled “Ask Someone Else” which allows participants to copy someone else within their group. The number ‘7’ at the bottom is a countdown timer that forces participants to answer within 15 seconds. The second image represents what a participant would see if they chose to “Ask Someone Else” in Round 2 of Condition C, where they could choose to either view Times Chosen Altogether (domain-general prestige) or Times Chosen On This Topic (domain-specific prestige). The bottom image represents what a participant would see if they chose ‘Times Chosen Altogether’ and (domain-general prestige), in which there were only two other players to choose from. Please note that for any given question, participants could have between one and nine other participants to choose from, depending on how many answered individually for that particular question. See Table 1 for the information combinations displayed in the other Conditions. See S1 File for screenshots for all Conditions.
