the cleavage response (in psychology)

The cleavage response in psychology refers to how individuals form and maintain emotional or social boundaries based on perceived group identities, such as gender, ethnicity, or beliefs. When someone identifies strongly with a particular group, they tend to view members of that group more favorably and may distance themselves from outsiders. This response helps reinforce a sense of belonging and safety but can also lead to polarization or bias. Essentially, it’s the psychological process of distinguishing “us” from “them” to strengthen group cohesion and personal identity.
