Researchers associated with UC Santa Barbara’s Center for Evolutionary Psychology, Professors Leda Cosmides and John Tooby and postdoctoral scholars Andrew Delton and Max Krasnow, have found that generosity may be based more on human nature than social pressure. Through computer simulations, they show that humans tend to help others, even if there is not a short-term personal gain, because natural selection favors treating the interaction as if it will happen again. Their findings were published in the Proceedings of the National Academy of Sciences. For more information, visit http://www.psych.ucsb.edu/research/cep/topics/HumanGenerosity.htm.
