Social Proof operates on uncertainty reduction:

When facing decisions, people ask:

┌─────────────────────────────────────────────────┐

│ "What are others doing in this situation?" │

│ "How many people have done this before me?" │

│ "Do people like me use this product?" │

└─────────────────────────────────────────────────┘

More people doing something = Safer choice to follow

This creates the BANDWAGON EFFECT:

Adoption → More Social Proof → More Adoption → ...

```

| Condition | Description |

| --------------- | ---------------------------------------------------- |

| Uncertainty | Most powerful when people feel unsure |

| Similarity | Stronger when reference group is similar to observer |

| Expertise | More influential when others perceived as experts |

| Numbers | Effect increases with size of conforming group |
