Multi-lab effort partially replicates Rand, Greene & Nowak 2012 cooperation under time pressure results

cooperate-timelimit
In 2012, David Rand, Joshua Greene, and Martin Nowak published 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.

MIT biophysicists use "the envelope game" to describe personal relations

"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.
