Chimps are no Chumps

2-minute read

Whether or not we get treated fairly is one of the metrics that humans use to assess the quality and potential longevity of our relationships. Ideally, we seek to collaborate with partners in all realms of our existence who acknowledge our contributions and expectations and are as attentive to our treatment as they are to their own.

Unremedied inequity can lead to a negative interpretation of events, a breakdown in communication, and an unwillingness to cooperate on future endeavors. According to a series of landmark studies, we share our desire for fair treatment and rejection of injustice with some savvy members of the animal kingdom—particularly when it comes to equal pay for equal work.

Do I Look Like I Just Fell Out of a Tree?
Behavioral researchers from Emory University examining non-human primates’ response to equal versus unequal rewards for completing a task revealed that the perceptive animals did not respond well to being taken advantage of.

When chimpanzees and capuchin monkeys and their task partners both received cucumber slices for their efforts, they were equally satisfied with the outcome. Given a choice, however, the animals prefer to be paid in grapes. If only one partner received grapes, the unfair compensation resulted in outright primate protest from the other, and refusal to either continue the task or to accept the inferior reward. In some cases, the work stoppage and reward rejection were accompanied by water spitting and cage-rattling to drive the dissatisfaction home.

Interestingly, to preserve a valued long-term relationship, some chimps would react to the unfair treatment of their partners by refusing the better reward. Researchers believe that the short-term sacrifice was not necessarily driven by a desire to do the right thing but to increase the odds of future cooperation by maintaining a basic sense of fairness. Similar to the realm of human relations, more equitable individual outcomes for the chimps had a greater likelihood of leading to more stable and harmonious interactions in their communities—wise apes.
