Social Proof

Social proof is important to know because in most pickups, the social aspect comes before attraction. Hot women won't interact with guys who show they're thinking of sex first. Guys are expected to work the room to meet hot womens' attraction criteria of being someone with high status before she will be receptive to escalation. Remember hot women are ruthless in their rejection mechanism, having social proofs piques her interest and goes from there. Social proof means that other people in the social situation acknowledge that you are a higher tier of guy which means you are on a higher level socially. This is important because the social matrix is value based and social proof is one way guys can architect a social situation where they are the center.
