Social Norms
Groups quietly shape behavior.
Shrink Definition
Social norms are the shared expectations, explicit or implicit, that influence how members of a group think, feel, and behave. Norms help coordinate behavior, reduce uncertainty, and promote cooperation within families, organizations, cultures, and societies. People often follow norms automatically without consciously recognizing their influence.
Plain language
People are strongly influenced by what they believe others expect.
Shrink Insight
Many decisions that feel personal are influenced by social expectations.
Why it matters

Medical boundary
This concept is educational and shouldn't be used to self-diagnose. It doesn't replace care from a licensed clinician. Symptoms, medication, and treatment decisions should be discussed with a qualified professional, and emergency symptoms require emergency care.
Evidence summary
Social norms are a foundational construct in social psychology, sociology, behavioral economics, and public health. Research consistently demonstrates that perceived norms strongly influence health behaviors, cooperation, and decision-making. Medical Boundary Social influence doesn't eliminate personal responsibility or individual differences. People vary substantially in how strongly they respond to group expectations.
