The impact of similarity on coordination games requiring players to either match their choices (“strategic complements” – “Stag hunt” games) or decouple them (“strategic substitutes” – “Entry” games) without communicating. Curves represent estimated probabilities of choosing a potentially higher paying, but uncertain payoff (y-axis) (“UP”), given increasing values of a safe alternative (x-axis), when interacting with either similar or dissimilar (anonymous) counterparts. Similarity was based solely on the fact that counterparts similarly identified (or did not identify) with three personality-descriptive words. Estimates were obtained with a generalized logistic mixed model. Error bands represent 95% confidence bands for the fixed effects. Points are the observed percentages of UP choices. Stars indicate significant effects of similarity on the estimated probability of making a risky choice ^*p < 0.05, ^***p < 0.001.
