Experiments have shown that primates more ethical and honest than humans: chimpanzees have a sense of justice and can be a brother to share food with neighbors.
In the experiment, the animals forced to play in the economic game adapted "Ultimatum." The rules are simple: the player must share with fellow food or money, but a second player can refuse to offer him a resource, and then both players will be left with nothing.
Studies in humans have shown that if the share of the resource, which is willing to share one player does not exceed 20%, the second player rejects the offer. On the one hand, such a behavior is at odds with the economic performance of the rationality of people, but if you look at it from the point of view of economy, but anthropology, it becomes obvious that such a solution indicates the presence of the people’s sense of justice. That is, it forces us to sacrifice the necessary resources in order to punish the offender.
In an experiment with monkeys as a resource were sliced banana. To get the bananas monkey had to take a scientist plastic badge and give it through the bars of his kinsman. The latter, in turn, had to return the token to the experimenter. At that chimpanzees could choose one of two tokens: the one that correspond to the same distribution of bananas, or the one who distributed the "resources" in the ratio of 5:1.
In the vast majority of cases (92%) of primates made a choice in favor of a "fair" token. The researchers note that during the experiment, no monkey did not try to cheat. Moreover, none of the primates in the study did not seek to punish the neighbor. Based on these data, scientists concluded that chimpanzees - very fair animals, maybe even more just than humans.
