// Using others' behavior as evidence of the "correct" action (Cialdini).
Social proof (Cialdini, 1984) — using others' behavior as evidence of the correct action.
Market expressions:
• "Everyone is buying crypto — it must be good"
• Following influencer/expert recommendations blindly
• Popularity of a stock = perceived quality
• Crowded trades feel safe — until they reverse simultaneously
Social proof works well in stable, familiar environments. It fails catastrophically in uncertain, novel situations — exactly when you need independent thinking most.
Pattern bridge: Copying others as a decision shortcut is an
embedding heuristic — if nearby vectors do it, so should I. In statistics, it’s the
law of large numbers misapplied: consensus ≠ correctness.
