  • Dogs have an intuitive understanding of fair play and become resentful if they feel that another dog is getting a better deal, a new study has found.

  • We demonstrate that, like capuchin monkeys, chimpanzees show a response to inequity of rewards that is based upon the partner  receiving the reward rather than the presence of the reward alone.

  • Here we demonstrate that a nonhuman primate, the brown capuchin monkey (Cebus apella), responds negatively to unequal reward distribution in exchanges with a human experimenter.

  • Researchers studying brown capuchin monkeys (Cebus apella) have found that the highly social, cooperative species native to South America show a sense of fairness, the first time such behavior has been documented in a species other than humans.

While the new study demonstrates that humans are not completely focused on their own self-interests, it is unclear how the physiological evidence translates to behaviors in real-world circumstances. Humans experience physiological and emotional rewards from helping others and donating to charities, but the brain seems to stop short of wanting to redistribute wealth across the board. The association between work, reward and equality, and the brain’s mechanisms underlying all of them, remain unclear.

When economists first started playing this game in the early 1980s, they assumed that this elementary exchange would always generate the same outcome. The proposer would offer the responder approximately $1⎯a minimal amount⎯and the responder would accept it. After all, $1 is better than nothing, and a rejection leaves both players worse off. Such an outcome would be a clear demonstration of our innate selfishness and rationality.
