We conducted an experiment to describe how social learners use information about the relation between payoffs and behavior. Players chose between twontechnologies repeatedly. Payoffs were random, but one technology was better because its expected payoff was higher. Players were divided into two groups:n1) individual learners who knew their realized payoffs after each choice andn2) social learners, who had no private feedback about their own payoffs, but in each period could choose to learn which behavior had produced the lowestnpayoff among the individual learners or which behavior had produced the highest payoff. When social learners chose to know the behavior producing the highest payoff, a model of imitating this successful behavior matches the data verynclosely. When social learners chose to know the behavior producing the lowest payoff, they tended to choose the opposite behavior in early periods, while increasingly choosing the same behavior in late periods. This kind of rapidntemporal heterogeneity in the use of social information has received little or no attention in the theoretical study of social learning.
