Strategic sophistication across clusters, phases and treatments. Participants were clustered in three groups through a mixture models cluster analysis on the proportion of level-2 choices in the Assessment phase (Low-sophistication, Medium-sophistication and High-sophistication). For each cluster, we plot the proportion of level-2 choices by phase Assessment, Observation and Re-assessment) and treatment (No-feedback, Pre-feedback, Post-feedback). Error bars represent standard errors. In the Medium-sophistication cluster, we show an effect of social learning (Re-assessment–Assessment) in the Post-feedback treatment but not in the Pre-feedback treatment.
