Social Proof

Social Proof is the psychological phenomenon where people look to others’ behavior to determine the correct course of action. In UX, it helps build trust and influence user decisions by showcasing endorsements, reviews, or popularity signals.

The Psychology Behind It

Humans are naturally influenced by group behavior and seek validation from others before making decisions. This is rooted in herd mentality, where people assume that if many others trust or use something, it must be valuable.
