The bandwagon effect is when people follow the actions or thoughts of others without considering their own beliefs. It is a cognitive bias that can be seen in social interactions and reinforced by other biases. It can be harmful, especially when it comes to ideals and ethics. In business, it can lead to groupthink and a crowded market. Awareness of the bandwagon effect can help individuals make calculated decisions based on their values.
The bandwagon effect is an observed social behavior in which people tend to go along with what others do or think without regard for their own actions. The likelihood of this happening has greatly increased as more and more people adopt an idea or behavior; this has led to the pejorative description of the “herd effect” in reference to this interesting behavioral phenomenon. It can be seen at nearly every level of human interaction, and being aware of its influence can help individuals make calculated decisions based on their beliefs and values rather than the temptation to get along with a group.
Social psychologists consider the bandwagon effect to be one among a large group of cognitive biases. A cognitive bias is behavior based on errors in memory, statistics, and social attribution. This particular behavior is reinforced by a number of other cognitive biases and psychological phenomena. When people decide to join a social networking site or listen to the same band, these are classic examples of this effect.
This phenomenon gets its name from the political term “jumping on the bandwagon,” which refers to the tendency of voters to align themselves with the biggest and most successful campaign. As more and more voters express support for a candidate or measure, the pool grows exponentially. The “winner’s wagon” in “jump on the winner’s wagon” was a literal wagon used by a political candidate in the 1800s on a promotional tour.
Depending on the circumstances, this effect can be benign or rather harmful. It is especially harmful when it comes to ideals and ethics; it only takes a small member of determined people to promote ideas that can be harmful to a society. For example, a handful of people might promote hateful racial generalizations that spread to the rest of a culture via the bandwagon effect, leading to discrimination against members of that race. Once the bandwagon has started, so to speak, it can be difficult to undo the damage that has been done.
In the business world, the bandwagon effect can be very dangerous. Members of a company’s development team, for example, may not see flaws in a project because they want to support team members, in a related concept called groupthink. The effect can also lead to a sudden explosion of similar products that eventually crowd the market, causing customers to deplete their interest and leaving businesses stranded.
