Bandwagon is a persuasive technique used by people to convince others to believe or do something because "everyone else is doing it." Essentially, it is a way of appealing to someone's desire to fit in or be part of a popular trend. The idea is that by making someone feel like they are part of a majority or a movement, they will be more likely to accept the message or idea being promoted. In other words, it's like saying "join us because everyone else is already on board!"
