Morality binds and blinds. It binds us into ideological teams that fight each other as though the fate of the world depended on our side winning each… - Jonathan Haidt

If you grow up in a WEIRD society, you become so well educated in the ethic of autonomy that you can detect oppression and inequality even where the apparent victims see nothing wrong.

When bad things happen to good people, we have a problem. We know consciously that life is unfair, but unconsciously we see the world through the lens of reciprocity. The downfall of an evil man (in our biased and moralistic assessment) is no puzzle: He had it coming to him. But when the victim was virtuous, we struggle to make sense of his tragedy. At an intuitive level, we all believe in karma, the Hindu notion that people reap what they sow. The psychologist Mel Lerner has demonstrated that we are so motivated to believe that people get what they deserve and deserve what they get that we often blame the victim of a tragedy, particularly when we can’t achieve justice by punishing a perpetrator or compensating the victim.

We should not expect individuals to produce good, open-minded, truth-seeking reasoning, particularly when self-interest or reputational concerns are in play. But if you put individuals together in the right way, such that some individuals can use their reasoning powers to disconfirm the claims of others, and all individuals feel some common bond or shared fate that allows them to interact civilly, you can create a group that ends up producing good reasoning as an emergent property of the social system. This is why it’s so important to have intellectual and ideological diversity within any group or institution whose goal is to find truth (such as an intelligence agency or a community of scientists) or to produce good public policy (such as a legislature or advisory board).
