Fig. 3.

The graph shows the average differences in rating (ratings 2 minus rating 1) with standard error bars. Results are shown separately for the adult social-influence condition and the teenager social-influence condition, for each age group. Bars on the left (‘Lower group ratings’) were from the conditions in which the social-influence group rated risk lower than participants' initial rating. Bars on the right (‘Higher group ratings’) were from the conditions in which the social-influence group rated risk higher than participants' initial rating. Asterisks indicate significant main effect of peer-influence (adults vs teenagers) within age group and interaction on peer-influence effects between age groups (** p < 0.01, * p < 0.05, black: Bonferroni corrected result; grey: uncorrected result).
