Lack of attraction to common behaviours. Shown is the average decrease in absolute difference between an individual's level of cooperation and the relevant social information; Mode: the most frequent behaviour among four individuals from another group (Other-group treatment, N = 180 observations on 48 individuals); Mode (coop): excludes cases where the mode = 0 (N = 136 observations on 48 individuals); Mean: the mean cooperation of four individuals from another group (Other-group, N = 240 observations on 48 individuals); Mean of means: the mean cooperation of three other groups (Group-means treatment, N = 240 observations on 48 individuals). A positive reduction in the absolute difference represents attraction, and a negative reduction represents aversion. Error bars are the 95% confidence intervals. In no cases is there a significant attraction towards the relevant common behaviour.
