Human intelligence is still a bit of an enigma. Researchers have some ideas about why advanced intelligence evolved in humans, but they have not come to a conclusive answer. One prominent idea is that intelligence serves a social function. In their new study, a group of researchers led by Jonathan Egeland reports additional evidence supporting this idea. According to their research, published in the journal Evolution and Human Behavior, greater intelligence seems to garner more respect, but only when it's applied to tasks that help others.
