PSYCHOLOGICAL CONCEPT
You walk into a restaurant. It is empty. You walk out. You walk into another restaurant. It is full. You stay. You did not know which restaurant was good. You followed the crowd.
QUICK ANSWER
Social proof is the tendency to follow what others do. It is a psychological phenomenon where people copy the actions of others in an attempt to reflect correct behavior. The concept was popularized by Robert Cialdini in his book 'Influence.' Social proof is why reviews matter, why trends go viral, and why you trust the crowd.
Social proof is simple: you follow the crowd. If other people are doing something, you assume it is correct. You trust the crowd more than yourself.
The bias is not about being stupid. It is about being efficient. Following the crowd is usually a good shortcut. But it can also lead to errors.
When making a decision, ask: am I following the crowd? Is the crowd right?
