# Social Proof Psychology

## Goal

Show credible evidence that relevant others trust, use, or benefit from the product.
Use proof to reduce uncertainty, not to manipulate.

## Rules

- Use proof from people similar to the target user.
- Prefer specific, verifiable, recent proof.
- Put proof near decisions and claims.
- Match proof type to user risk.
- Avoid fake, vague, or inflated claims.
- Do not use social proof when evidence is weak or irrelevant.

## Proof Types

- Expert proof: credible authority, analyst, certification.
- User proof: testimonials, reviews, ratings.
- Customer proof: logos, case studies, adoption stats.
- Peer proof: friends, teams, similar companies.
- Behavioral proof: "popular", waitlists, live activity, recent purchases.

## Flow

1. Identify decision point and hesitation.
2. Define target user segment.
3. Inventory available proof.
4. Remove weak or unverifiable proof.
5. Choose proof matching the audience.
6. Place proof near relevant CTA or claim.
7. Define metrics to test impact.

## Good Proof

- Names, roles, company, photo when allowed.
- Specific outcome or metric.
- Relevant industry or use case.
- Recent date or current usage.
- Link to full case study when possible.

## Mistakes

- Generic testimonials.
- Logo walls with no relevance.
- Big numbers without context.
- Fake scarcity or fake popularity.
- Proof aimed at wrong segment.
- Proof hidden below the decision point.
