Social Proof (Consensus)
Social proof, also called consensus, is the pull of the crowd. If many people chose something, it feels like a safer choice for you. Reviews, “best seller” badges, and a packed restaurant all use it. The pull is strongest when you are unsure.
Solomon Asch showed people would even match a wrong answer to stay with the group. A hotel study found a sign that said guests in this room reused towels worked better than a generic “help the environment” sign. The “others” feel closer, so the proof hits harder. Fake counts and fake reviews use the same instinct.
