Our caveman past may be to blame for our ability to identify an untrustworthy man. To test if we have indeed evolved to spot untrustworthy men, researchers presented people with 100 photographs of men. The study results show both men and women successfully singled out those men who were untrustworthy with a success rate better than chance. The results show that men and women were more likely to judge men with masculine faces as being unfaithful, and that this was likely to be correct. Researchers also asked men and women to predict how likely women in photographs were to be unfaithful, but they did not manage to do this.
