Fairness Instinct: The Robin Hood Mentality and Our Biological NatureBiologist L. Sun examines the innate sense of fairness displayed by human beings in all kinds of societies throughout history. He argues persuasively that it is an emotion and behavior rooted in our DNA, rather than a product of ideology or convention. Citing animal studies that show that even monkeys react negatively to patently unfair treatment, Sun delves into the issue of why this instinct may have evolved with a new biological framework.
