Individual probability of inferring the correct rule after n successful combinations. Individual learners (n = 34, red line) needed to produce less successful combinations to exhibit the same probability of inferring the rule than social learners (n = 39, blue line). Social learners’ data set were limited to periods in between the beginning of the experiment and the appearance of groups’ first rule guesser. During these periods, social learners were still actively searching for solutions and were provided with social information in an irregular fashion (see Supplementary Table 2). After the appearance of a first rule guesser, other group members were likely to be constantly provided with social information. Non-first guesser social learners (n = 29) produced between 10 to 27 successful combinations during the learning phase and reported the correct rule with a probability of 0.38 (dotted line). Our analyses suggest that constant access to social information further decreased individuals’ cognitive effort (see main text). Individual learners who never scored were removed from this analysis (6 out of 40). One social learner was removed because the rule he/she reported was considered as ambigous by the coders (see Supplementary Material for details). Solid lines show mean posterior probabilities and 95% HPDIs.
