Chimps and Bonobos Found to Lack Sense of Fairness, Uniquely Human Characteristic
The scientists, including Prof. Keith Jensen, from Queen Mary’s School of Biological and Chemical Sciences, put the apes through a series of ultimatum games. One against the other, they had to choose whether to steal or leave the other’s grapes. The games were set up in a variety of different ways involving equal proportions of grapes and others were split with a higher proportion given to one over the other.
“In each scenario one ape had to choose whether to steal the grapes or leave a portion of grapes for the other. We found that consistently they would steal the food without taking into account whether their action would have an effect on their partner.”
“Neither the chimpanzees nor bonobos seemed to care whether food was stolen or not, or whether the outcomes were fair or not, as long as they got something. Our findings support other studies of chimpanzees but also extend these to bonobos. Both apes have no concern for fairness or the effects that their choices may have on others; in stark contrast to the way humans behave,”
