Bright red coloration is a signal of male competitive ability in animal species, including non-human primates. Does the effect of red on competition extend to humans?

A landmark study in evolutionary psychology established such an effect through analysis of data for four combat sports at the 2004 Athens Olympics (Hill & Barton 2005). We show that the observed pattern reflects instead a structural bias towards wins by red in the outcomes of the competition. Consistently, we find no effect of red in equivalent data for the 2008 Beijing Olympics, which present a structural bias towards wins by blue. These results refute past claims of an effect of red on human competition based on analysis of this system. In turn, this undermines the notion that any effect of red on human behavior is an evolved response shaped by sexual selection. Results from the largest test of the effect to date, based on outcomes of contests in an online game, support this conclusion.
