In this amazing video, which I found on Americans Against the Tea Party, some Capuchin monkeys are given identical tasks to complete in order to receive payment in the form of a tasty treat. However, they give one monkey a cucumber slice, that deliciously bland veggie, and the other monkey a grape, a far tastier treat. The cucumber monkey will not stand for it.
I love the basic understanding of these monkeys that unequal pay is not fair. I hope they made up for it by giving the cucumber monkey lots of grapes afterward. That’s scientific ethics, right?
