Right brain area linked to fairness
By Bruce Bower
The ability to control selfish impulses in order to reject an unfair deal depends on a specific right brain area, a new study finds.
A team led by Daria Knoch of the University of Zurich focused on a game in which one person makes an offer to another person on how to split a pot of money. The second person can either accept the offer and pocket the offered portion, or refuse it, leaving both players with nothing. Responders typically reject offers of less than 25 percent of the pot, preferring zilch to an unfair deal.
