It's a cognitive bias that causes people to think or act in a certain manner because they believe that other people are doing the same.
For example, the bandwagon effect might cause someone to adopt a certain political ideology, simply because influential people in their social circle have adopted the same ideology.
It serves as a mental shortcut that people instinctively use in order to make a decision quickly.
Specifically, bandwagon cues, which are signs that other people believe something or are doing something, can trigger the thought that “if other people like this, then I should too”.
For example, you could choose to openly display social proof or bandwagon cues, in order to signal to other people that there is support for whatever it is you are promoting.
Video-sharing sites demonstrate the benefits of displaying these cues, since people often use popularity cues such as the number of views that a video has in order to decide whether to watch it or not.
The Influence on others happens in several ways:
It occurs primarily due to the fact that we tend to naturally examine and remember events primarily through our personal point of view.
Even when we realize that we should adjust our perspective to see things through other people’s eyes, we tend to anchor this new perspective to our own, and we often fail to adjust from our original viewpoint enough to properly assess how other people feel.
Since we spend the majority of the time experiencing things from our own perspective, we struggle to imagine the perspective of others.
The curse of knowledge is a cognitive bias that makes it difficult for people to account for the fact that other people’s thoughts, beliefs, and views are different from their own.
