6. Lack of ear symmetry
One study found that people who are less symmetrical, like those who have one earlobe or finger longer than its twin, make better leaders and are able to avoid self-interest. It’s possible that people’s reactions to these unusual body parts cause them to develop stability.
7. Thin, smiling lips
Men might not often showcase their lips with balm or make-up, but they could still make a statement. Scientists believe that thin, smiling lips can help a man appear more intelligent. Sad lips were taken as a sign that men were less than intelligent. While it is unclear just how corelative this was, humans have grown to unconsciously recognize this feature over time.
