The bandwagon effect has been applied to situations involving [[majority opinion]], such as political outcomes, where people alter their opinions to the majority view.{{sfn|McAllister| Studlar|1991}} Such a shift in opinion can occur because individuals {{Clarify | text = draw inferences | date = August 2022 | reason = Draw inferences about what?  The reference doesn't say either; this is a verbatim sentence.}} from the decisions of others, as in an [[informational cascade]].<ref>{{Cite web | url = http://dumaguetemetropost.com/beware-of-the-bandwagon-effect-other-cognitive-biases-p7272-99.htm | title = Beware of the bandwagon effect, other cognitive biases | website = dumaguetemetropost.com | access-date = 2017-12-08 | archiveurl = https://web.archive.org/web/20210224124642/http://dumaguetemetropost.com/beware-of-the-bandwagon-effect-other-cognitive-biases-p7272-99.htm | archivedate = 2021-02-24 | url-status = dead}}</ref>

Perceptions of popular support may affect the choice of activists about which parties or candidates to support by donations or voluntary work in campaigns. They may strategically funnel these resources to contenders perceived as well supported and thus electorally viable, thereby enabling them to run more powerful, and thus more influential campaigns.<ref name=":6" />

===In economics===
American economist [[Gary Becker]] has argued that the bandwagon effect is powerful enough to flip the [[demand curve]] to be upward sloping. A typical demand curve is downward sloping—as prices rise, [[demand]] falls. However, according to Becker, an upward sloping would imply that even as prices rise, the demand rises.<ref name=":3" />

====Financial markets====
The bandwagon effect comes about in two ways in [[financial market]]s.

First, through [[price bubble]]s: these bubbles often happen in financial markets in which the price for a particularly popular [[Security (finance)|security]] keeps on rising. This occurs when many [[investor]]s line up to buy a security [[bidding]] up the price, which in return attracts more investors. The price can rise beyond a certain point, causing the security to be highly [[Overvaluation|overvalued]].<ref name=":3" />

Second is [[liquidity]] holes: when unexpected news or events occur, [[market participant]]s will typically stop trading activity until the situation becomes clear. This reduces the number of buyers and sellers in the market, causing liquidity to decrease significantly. The lack of liquidity leaves [[price discovery]] distorted and causes massive shifts in [[Asset pricing|asset prices]], which can lead to increased panic, which further increases uncertainty, and the cycle continues.<ref name=":3" />

====Microeconomics====
{{See also|Network effect|Veblen good}}
In [[microeconomics]], bandwagon effects may play out in interactions of demand and preference.<ref name="harvey">{{cite journal |author-link= Harvey Leibenstein |first= Harvey |last= Leibenstein |title= Bandwagon, Snob, and Veblen Effects in the Theory of Consumers' Demand |journal= [[Quarterly Journal of Economics]] |year= 1950 |volume= 64 |issue= 2 |pages= 183–207 |doi= 10.2307/1882692 |jstor= 1882692 }}</ref> The bandwagon effect arises when people's preference for a commodity increases as the number of people buying it increases. Consumers may choose their product based on others' preferences believing that it is the superior product. This selection choice can be a result of directly observing the purchase choice of others or by observing the scarcity of a product compared to its competition as a result of the choice previous consumers have made. This scenario can also be seen in restaurants where the number of customers in a restaurant can persuade potential diners to eat there based on the perception that the food must be better than the competition due to its popularity.<ref name=":0" /> This interaction potentially disturbs the normal results of the theory of [[supply and demand]], which assumes that consumers make buying decisions exclusively based on price and their own personal preference.<ref name=":3" />

=== In medicine ===
Decisions made by medical professionals can also be influenced by the bandwagon effect. Particularly, the widespread use and support of now-disproven medical procedures throughout history can be attributed to their popularity at the time. Layton F. Rikkers (2002), [[professor emeritus]] of surgery at the [[University of Wisconsin–Madison]],<ref>{{Cite journal|doi = 10.1016/s1091-255x(02)00054-9|title = The Bandwagon Effect|year = 2002|last1 = Rikkers|first1 = L.|journal = Journal of Gastrointestinal Surgery|volume = 6|issue = 6|pages = 787–794|pmid = 12504215|s2cid = 24723738}}</ref> calls these prevailing practices '''medical bandwagons''', which he defines as "the overwhelming acceptance of unproved but popular [medical] ideas."<ref name=":5" />

Medical bandwagons have led to inappropriate therapies for numerous patients, and have impeded the development of more appropriate treatment.<ref>{{Cite journal|last=Paumgartten|first=Francisco José Roma|title=Phosphoethanolamine: anticancer pill bandwagon effect|journal=Cadernos de Saúde Pública|year=2016|language=en|volume=32|issue=10|pages=e00135316|doi=10.1590/0102-311X00135316|pmid=27783758|issn=0102-311X|doi-access=free}}</ref>

One paper from 1979 on the topic of bandwagons of medicine describes how a new medical concept or treatment can gain momentum and become mainstream, as a result of a large-scale bandwagon effect:<ref>{{Cite journal|doi = 10.1353/pbm.1979.0037|title = The Bandwagons of Medicine|year = 1979|last1 = Cohen|first1 = Lawrence|last2 = Rothschild|first2 = Henry|journal = Perspectives in Biology and Medicine|volume = 22|issue = 4|pages = 531–538|pmid = 226929| s2cid=10758319 }}</ref>

* The [[news media]] finds out about a new treatment and publicizes it, often by publishing pieces.
* Various organizations, such as government agencies, research foundations, and private companies also promote the new treatment, typically because they have some vested interest in seeing it succeed.
* The public picks up on the now-publicized treatment, and pressures medical practitioners to adopt it, especially when that treatment is perceived as being novel.
* Doctors often want to accept the new treatment, because it offers a compelling solution to a difficult issue.
* Since doctors have to consume large amounts of medical information in order to stay aware of the latest trends in their field, it is sometimes difficult for them to read new material in a sufficiently critical manner.

=== In sports ===
{{Main|Bandwagon fan}}
One who supports a particular sports team, despite having shown no interest in that team until it started gaining success, can be considered a "[[bandwagon fan]]".<ref>{{Cite web|title=bandwagon fan|url=https://www.dictionary.com/e/pop-culture/bandwagon-fan/|access-date=2020-10-30|website=Dictionary.com|language=en-US}}</ref>

=== In social networking ===

As an increasing number of people begin to use a specific social networking site or application, people are more likely to begin using those sites or applications. The bandwagon effect also {{Clarify | text = affects random people that which posts are viewed and shared. | date = August 2022 | reason = This is either unintelligible or can be interpreted multiple ways.}}<ref>{{Cite journal|title=The bandwagon effect on participation in and use of a social networking site|year=2012|url=https://firstmonday.org/ojs/index.php/fm/article/view/3971/3207|last1=Fu|first1=W.

This research used bandwagon effects to examine the comparative impact of two separate bandwagon heuristic indicators (quantitative vs. qualitative) on changes in news readers' attitudes in an online comments section. Furthermore, Study 1 demonstrated that qualitative signals had a higher influence on news readers' judgments than quantitative clues. Additionally, Study 2 confirmed the results of Study 1 and showed that people's attitudes are influenced by apparent public opinion, offering concrete proof of the influence that digital bandwagons.<ref>{{Cite journal |last1=Lee |first1=Seungae |last2=Atkinson |first2=Lucy |last3=Sung |first3=Yoon Hi |date=2022 |title=Online bandwagon effects: Quantitative versus qualitative cues in online comments sections |url=http://journals.sagepub.com/doi/10.1177/1461444820965187 |journal=New Media & Society |language=en |volume=24 |issue=3 |pages=580–599 |doi=10.1177/1461444820965187 |s2cid=225115492 |issn=1461-4448 |via=Sage Journals|url-access=subscription }}</ref>

=== In fashion ===
The bandwagon effect can also affect the way the masses dress and can be responsible for clothing trends. People tend to want to dress in a manner that suits the current trend and will be influenced by those who they see often – normally celebrities. Such publicised figures will normally act as the catalyst for the style of the current period. Once a small group of consumers attempt to emulate a particular celebrity's dress choice more people tend to copy the style due to the pressure or want to fit in and be liked by their peers.{{citation needed|date=May 2021}}
