When group membership is inescapable, people must accommodate internal differences managefully.

Evidence

In societies low in relational mobility, group membership is generally ascribed and predetermined. People cannot escape from their groups even if they find that their own attitudes, goals, and so on are not fully compatible with those of their fellow group members. It is, thus, critically important to maintain good relationships with one’s in-group members, by recognizing and accommodating individual differences in attitudes, goals, and so on within the group (Adams et al., 2004). Moreover, to be successful, one must also navigate friction between other in-group members, requiring great attention to the in-group’s complex relational networks. — Roderick M. Kramer, Geoffrey J.
