This tendency of people to align their beliefs and behaviors with those of a group is also called a herd mentality.

Understanding the Bandwagon Effect
The bandwagon effect arises from psychological, sociological, and, to some extent, economic factors. People like to be on the winning team and they like to signal their social identity. Economically, some amount of bandwagon effect can make sense, in that it allows people to economize on the costs of gathering information by relying on the knowledge and opinions of others. The bandwagon effect permeates many aspects of life, from stock markets to clothing trends to sports fandom.
In politics, the bandwagon effect might cause citizens to vote for the person who appears to have more popular support because they want to belong to the majority. The term "bandwagon" refers to a wagon that carries a band through a parade. During the 19th century, an entertainer named Dan Rice traveled the country campaigning for President Zachary Taylor. Rice's bandwagon was the centerpiece of his campaign events, and he encouraged those in the crowd to "jump on the bandwagon" and support Taylor. By the early 20th century, bandwagons were commonplace in political campaigns, and "jump on the bandwagon" had become a derogatory term used to describe the social phenomenon of wanting to be part of the majority, even when it means going against one's principles or beliefs.
Consumers often economize on the cost of gathering information and evaluating the quality of consumer goods by relying on the opinions and purchasing behavior of other consumers. To some extent, this is a beneficial and useful tendency; if other people's preferences are similar, their consumption decisions are rational, and they have accurate information about the relative quality of available consumer goods, then it makes perfect sense to follow their lead and effectively outsource the cost of gathering information to someone else.
However, this kind of bandwagon effect can create a problem in that it gives every consumer an incentive to free ride on the information and preferences of other consumers. To the extent that it leads to a situation where information regarding consumer products might be underproduced, or produced solely or mostly by marketers, it can be criticized. For example, people might buy a new electronic item because of its popularity, regardless of whether they need it, can afford it, or even really want it.
Bandwagon effects in consumption can also be related to conspicuous consumption, where consumers buy expensive products as a signal of economic status.
Investment and Finance
Investing and financial markets can be especially vulnerable to bandwagon effects because not only will the same kind of social, psychological, and information-economizing factors occur, but additionally the prices of assets tend to rise as more people jump on the bandwagon. This can create a positive feedback loop of rising prices and increased demand for an asset, related to George Soros' concept of reflexivity.
For example, during the dotcom bubble of the late 1990s, dozens of tech startups emerged that had no viable business plans, no products or services ready to bring to market, and in many cases, nothing more than a name (usually something tech-sounding with ".com" or ".net" as a suffix). Despite lacking in vision and scope, these companies attracted millions of investment dollars in large part due to the bandwagon effect.
