" Social Proof The concept of social proof comes from influence psychology and is well documented in everything from salesmanship to advertising, to politics, and to attraction and relationships. The idea is that as humans when we see many other people valuing something, we will unconsciously value it ourselves. For instance, if everybody else is talking about a new movie, we are more likely to want to see it because we’ll unconsciously assume that it’s a good or important movie to see. "
