Why Do Good? Brain Study Offers Clues
People may not perform selfless acts just for an emotional reward, a new brain study suggests. Instead, they may do good because they're acutely tuned into the needs and actions of others.
Scientists say a piece of the brain linked to perceiving others' intentions shows more activity in unselfish vs. selfish types.
"Perhaps altruism did not grow out of a warm-glow feeling of doing good for others, but out of the simple recognition that that thing over there is a person that has intentions and goals. And therefore, I might want to treat them like I might want them to treat myself," explained study author Scott Huettel, an associate professor of psychology at Duke University Medical Center, in Durham, N.C.
For decades, psychologists and neuroscientists have puzzled over the tendency of humans to engage in altruistic acts -- defined by Huettel's group as acts "that intentionally benefit another organism, incur no direct personal benefit, and sometimes bear a personal cost." more
