Individual Level Within-Group Mechanism
EVENT
In order to obtain a better understanding of the group-level results, we conducted a set of (within-group) individual-level analyses, to estimate the role of social information—holding a minority opinion—in determining the decisions of group members: namely, whether they change their choice in the subsequent round. Following the advice of Morgan and Laland (Table GEE estimation of group members’ choice changeLogit estimates with group clustered standard errors in parentheses; *** 
(Both social and asocial information were found to predict an individual’s likelihood of changing their subsequent choice, but these effects vary across group conditions and stages of the game. In the stable stage (rounds 1–60: Model 5), social information (holding a minority opinion) increases the likelihood of changing one’s subsequent choice. This effect is smaller and marginally significant in the LoConf group condition (In both stages of the game, asocial information (receiving a higher payoff) decreased the propensity of players to change their subsequent choice, as expected. This effect was identified only when players’ choices aligned with the group. Instead of a reversed effect in the event of being in the minority, the effect became small and statistically insignificant. This pattern was similar for both group conditions and did not significantly alter across the two stages of the game. Furthermore, the effect of asocial information on majority group members was not significantly different from its effect on players in the individual condition. These results are depicted in Fig. These findings provide an individual-level account for the varying group-level adaptability under high and low conformity. Whereas asocial information in our setting is a noisy yet unbiased signal that facilitates learning and adaptation, social information is based on accumulated learning and therefore reflects Given this varying utility of social information in stable and altered environments, the finding that social information becomes less influential among members of LoConf groups when the environment changes, whereas it increases its influence among members of HiConf groups (Fig.
