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 battle. It blinds us to the fact that each team is composed of good people who have something important to say.
Morality binds and blinds. It binds us into teams … but thereby makes us go blind to objective reality.
Dividing into teams doesn't necessarily mean denigrating others. Studies of groupishness have generally found that groups increase in-group love far more than they increase out-group hostility.
Our moral sense really evolved to bind groups together into teams that can cooperate in order to compete with other teams.
If our goal is to understand the world, to seek a deeper understanding of the world, our general lack of moral diversity here is going to make it harder. Because when people all share values, when people all share morals, they become a team.
