Psychology of Social Proof
Social proof is psychological shortcut—when uncertain, we look to others' behavior for guidance. If others chose this option, it's probably good.
This tendency is deep-seated. We're social creatures who learn from collective behavior. Marketing that leverages social proof taps fundamental psychology.
Effective social proof feels authentic and relevant. Manufactured or irrelevant proof fails to persuade.
