In-Group Favoritism
“A minimal boundary divides “us” from “them.” Sometimes that alone shifts the allocation.”
01 / SUMMARY
In short
Group membership can favor evaluations or resources for people who share the category. Minimal-group experiments show that even arbitrary divisions can matter, although they do not always create hostility.
03 / SCENE
In the wild
People randomly assigned to teams with no shared history may allocate slightly more points to their own team.
04 / LIMIT
The limit
Favoring one's group does not necessarily mean disliking another, and the effect's strength depends on norms and context.
FINAL NOTE
What remains
When allocating opportunities, hide irrelevant affiliations and publish shared criteria before seeing candidates.
