Revisiting the revisit: added evidence for a social chemosignal in human emotional tears

In a study by Gelstein etal., we found that human emotional tears act as a social chemosignal. In the first of three different experiments in that study we observed that sniffing women's emotional tears reduced the sexual attractiveness attributed by men to pictures of women's faces. In a study partly titled Chemosignaling effects of human tears revisited, Graanin etal. claim failed replication of this effect in a series of experiments, one they described as exactly the same procedure as Gelstein. Given that Graanin etal. refused our extended offer to jointly replicate the experiment at our expense, we can merely comment on their effort. We find that Graanin, who are not a chemosignaling laboratory, used methodology that falls short of standards typically applied in chemosignaling research. Thus, their experiments were profoundly different from Gelstein. Finally, we found that in reanalysing their raw data we could in fact replicate the effect from Gelstein. Thus, we conclude that the failed replication in Graanin is neither a replication nor failed.
