There’s nothing like feeling validated based on what others are doing. People do what they observe other people doing. It’s safety in numbers, basically band wagoning.
The Bandwagon Effect is a type of Social Proof where people do something primarily because others are doing it. This is regardless of their own beliefs or personal preferences. The fear of missing out (FOMO) can drive this behavior, as individuals want to be part of the majority and not feel left out
Celebrities often have significant influence over public opinion, and their endorsements can serve as powerful Social Proof. When a well-known figure endorses a product or cause, it can sway public perception and behavior. For instance, when a popular actor promotes a charity on social media, their fans are more likely to donate. Therefore, believing that the cause is worthy of their support because of the celebrity’s endorsement.
