3. Use in politics
The bandwagon effect occurs in voting: some people vote for those candidates or parties who are likely to succeed (or are proclaimed as such by the media), hoping to be on the "winner's side" in the end.The bandwagon effect has been applied to situations involving majority opinion, such as political outcomes, where people alter their opinions to the majority view (McAllister and Studlar 721). Such a shift in opinion can occur because individuals draw inferences from the decisions of others, as in an informational cascade.

2. Origin of the phrase
Literally, a bandwagon is a wagon which carries the band in a parade, circus or other entertainment.The phrase "jump on the bandwagon" first appeared in American politics in 1848 when Dan Rice, a famous and popular circus clown of the time, used his bandwagon and its music to gain attention for his political campaign appearances. As his campaign became more successful, other politicians strove for a seat on the bandwagon, hoping to be associated with his success. Later, during the time of William Jennings Bryan's 1900 presidential campaign, bandwagons had become standard in campaigns,and "jump on the bandwagon" was used as a derogatory term, implying that people were associating themselves with the success without considering what they associated themselves with.

1.Definition
The bandwagon effect, also known as the "cromo effect" and closely related to opportunism, is a phenomenon—observed primarily within the fields of microeconomics, political science, and behaviorism—that people often do and believe things merely because many other people do and believe the same things. The effect is often called herd instinct, though strictly speaking, this effect is not a result of herd instinct. The bandwagon effect is the reason for the bandwagon fallacy's success.

乐队花车
从众效应又被称为「乐队花车效应」，也就是在花车大游行中 搭载乐队的花车。参加者只要跳上了这台乐队花车，就能够轻 松地享受游行中的音乐，又不用走路，也因此，英文中的片语 （跳上乐队花车）就代表了「进入主流」。这片语首先在 1848年的美国政府中，由林肯时代的一个小丑使用。专业的 马戏团小丑丹•赖斯，在为扎卡里•泰勒竞选宣传时，使用了乐 队花车的音乐来吸引民众注目。当泰勒的宣传日益成功时，越 来越多政客为求利益而投向了泰勒。1900年，威廉•詹宁斯•布 莱恩参选美国总统选举时，乐队花车已成为竞选不可或缺的一 部份。
