Would you take the bigger share? Study shows people can learn to say no

A new study co-authored by McGill University researchers suggests people can be taught to reject unfair advantages. "We often benefit personally from an unequal distribution of resources, a phenomenon known as advantageous inequity—for example, receiving a higher salary than a colleague with the identical role," said senior author Ross Otto, a psychology professor. "Here we ask whether people can learn to punish advantageous inequity merely by observing the inequity-averse preferences of another person."
