People may be more willing to help strangers who seem agreeable and conscientious, partly because these traits make the person more likeable, according to research published in Evolutionary Psychological Science.

A new study reveals that women anticipate harsh social judgments for boasting and strategically use modesty to navigate relationships with other women. The findings shed light on the unseen hurdles women face when self-promoting in the workplace.

A new theoretical framework proposes that "survival of the wittiest" drove early human evolution. By developing clever language, early humans swapped physical violence for verbal competition, changing the trajectory of human cognitive and brain development.

While anthropologists frequently credit meat consumption for the development of large human brains, new dietary modeling indicates that carbohydrates from fruit and honey actually provided the essential glucose required for hominin cognitive evolution.

A new psychological study reveals that when heterosexual men are sexually aroused, they are more likely to ignore a woman’s facial expressions and incorrectly assume she is flirting based solely on her revealing clothing.
