Rand Eyal Ert Kevin Lewis Steve Hershman and Michael I. Norton ABSTRACT—Psychological explanations of group genesis often require population heterogeneity in identity or other characteristics whether deep e.g. religion or superficial e.g. eye color . We use game theoretical agent based models to explore group genesis in homogeneous populations and find robust group formation with just two basic principles reciprocity and transitivity.
These emergent groups demonstrate in group cooperation and out group defection even though agents lack common identity. payoffs and group structure is robust to varying levels of reciprocity and transitivity. Increasing population size increases group size more than group number and manipulating baseline Bank Email List trust in a population has predictable effects on group genesis. An interactive online demonstration enables first hand exploration of the parameter space mpmlab groups and available source code supplementary materials provides a guide to implementing psychological agent based models.

Children Pay Forward Positive and Negative Outcomes to Conspecifics pdf By Leimgruber Kristin L. Adrian F. Ward Jane Widness Michael I. Norton Kristina R. Olson Kurt Gray and Laurie R. Santos ABSTRACT—The breadth of human generosity is unparalleled in the natural world and much research has explored the mechanisms underlying and motivating human prosocial behavior. Recent work has focused on the spread of prosocial behavior within groups through paying it forward a case of human prosociality in which a recipient of generosity pays a good deed forward to a third individual rather than back to the original source of generosity. While research shows that human adults do indeed pay forward generosity little is known about the origins of this behavior.
