Click here to take a peek behind the recent Nature paper that examines how the structure of a population affects its behavior, and whether some population structures may promote the evolution of cooperation.
In 2012, David Rand, Joshua Greene, and Martin Nowakpublished results showing that people who made quick decisions under time pressure were more likely to cooperate than were people who were required to take longer in their deliberations. Subjects who did not follow directions to respond at the pace requested were omitted from the analyzed data; now, a new report published in Perspectives on Psychological Science compiles studies by twenty-one laboratories to recreate the original results, and further finds that when non-compliant subjects are included, time pressure has little or no effect on cooperation.

"The envelope game", a framework developed by PED's Martin Nowak, Erez Yoeli, and Moshe Hoffman, gets a shoutout from MIT researchers who used it to find similarities between apparently unrelated types of interpersonal relations:
MIT postdoc Alfonso Pérez-Escudero and colleagues analyzed how these manipulation and preferential interaction mechanisms play out in 'the envelope game," a framework developed by Harvard University researchers Martin Nowak, Erez Yoeli, and Moshe Hoffman. "These are two situations that, in principle, I wouldn't put together, and thanks to the framework that these researchers developed, we realized that they belong to the same family of situations," Pérez-Escudero says.
