Capuchin monkeys are dry-nosed primates that live in the forests of Central America, the Amazon, Brazil and Argentina.
Capuchin Monkeys Want Fairness
They have a special sense of justice. In an experiment, the moneys were given little stones that they could swap for food.
One monkey was given a piece of cucumber, while the other received a tasty grape. A third monkey was watching all this and thought: “That’s not fair!”
He refused to swap his stone or rejected the cucumber he was given.
Capuchin Monkeys Compare Themselves to Others/h5>
The other monkeys got even madder when they saw that one monkey got a grape for nothing. But if there were no other monkeys nearby, there was no frustration.
Capuchin monkeys compare themselves/their property to other monkeys.
