As soon as we sort people into “us” and “them,” we start reading the exact same behavior in two different ways. Pick an action. Then flip the lens between the two groups. Watch the judgment follow the team, not the act. Last, try a real minimal group choice.
Pick an action
The action is the same both times. Only the team of the person doing it changes.
Same act, whose team?pick an action and a lens to begin
1. What happened?
2. Who did it? Flip the lens
The science. Even a coin flip is enough. In Henri Tajfel’s minimal group studies, people gave more rewards to their own group for no real reason at all. At Muzafer Sherif’s Robbers Cave camp, the same kind of rivalry flared up within days. It cooled only once the two groups shared a common goal.
The giveaway. Look at the verdict pill. “Us” always gets the benefit of the doubt. “Them” never does. The explanation flips to fit. Good acts by “us” show character, and bad acts are bad luck. For “them,” it is the reverse. That lopsided pattern is the ultimate attribution error.
Try it: the minimal group choice
A coin flip just put you in the Blue group. You will never meet anyone in either group. Pick how to hand out reward points between one Blue member (your group) and one Green member (the other group).
