Definition
Group identity is the internalized sense of belonging to social categories — family, community, profession, nation, faith — that shapes attention, memory, and behavior.
Why it matters
Group identity is both protective (belonging, meaning, health) and risky (in-group bias, intergroup conflict). Both truths matter.
The Science
Social identity theory (Tajfel, Turner) documents robust in-group favoritism and out-group differentiation, even under minimal group conditions. Neural correlates are found in medial prefrontal and reward circuits.
The NSI Perspective
NSI treats group identity as a real nervous-system phenomenon — not to be shamed and not to be uncritically celebrated.
Clinical Implications
Working with (and sometimes updating) group identity is part of thoughtful therapy — not marginal to it.
Practical Application
The groups you belong to shape you. Choose some of them deliberately.
