In the previous module we determined in many circumstances it was advantageous to imitate or socially learn from others. It was even shown that learning could increase the average welfare of a population if individuals selectively learned better behaviors at reduced cost and greater accuracy. What was left out, however, was how to do that. Is it advantageous to be selective about whom one learns from?
