Even Babies Will 'Sell Out' for a Price

"It's a study I like to call 'the deal with the devil,'" said study researcher Arber Tasimi, a graduate student in the Department of Psychology at Yale University. Tasimi and Yale psychologist Karen Wynn were interested in finding out the age at which kids will avoid a wrongdoer, even if it comes at a cost to the kids themselves. So Tasimi and Wynn decided to look at this moral dilemma in children on both sides of that age cutoff.
