Abstract

replying to G. Tinghög et al. Nature498,http://dx.doi.org/10.1038/nature12194(2013)

Tinghög et al.1 take issue with two of the ten experiments in our paper2 (studies 6 and 7). Here we reanalyse the data from these experiments as suggested by Tinghög et al.1, and demonstrate that our reported positive effect of time pressure on cooperation is not an artefact. Furthermore, an aggregate analysis based on fifteen studies and 6,910 decisions also replicates this effect3.
