Bandwagon effect

Last updated

The bandwagon effect is the tendency for people to adopt certain behaviors, styles, or attitudes simply because others are doing so. [1] More specifically, it is a cognitive bias by which public opinion or behaviours can alter due to particular actions and beliefs rallying amongst the public. [2] It is a psychological phenomenon whereby the rate of uptake of beliefs, ideas, fads and trends increases with respect to the proportion of others who have already done so. [3] As more people come to believe in something, others also "hop on the bandwagon" regardless of the underlying evidence.

Following others' actions or beliefs can occur because of conformism or deriving information from others. Much of the influence of the bandwagon effect comes from the desire to 'fit in' with peers; by making similar selections as other people, this is seen as a way to gain access to a particular social group. [4] An example of this is fashion trends wherein the increasing popularity of a certain garment or style encourages more acceptance. [5] When individuals make rational choices based on the information they receive from others, economists have proposed that information cascades can quickly form in which people ignore their personal information signals and follow the behaviour of others. [6] Cascades explain why behaviour is fragile as people understand that their behaviour is based on a very limited amount of information. As a result, fads form easily but are also easily dislodged.[ citation needed ] The phenomenon is observed in various fields, such as economics, political science, medicine, and psychology. [7] In social psychology, people's tendency to align their beliefs and behaviors with a group is known as 'herd mentality' or 'groupthink'. [8] The reverse bandwagon effect (also known as the snob effect in certain contexts) is a cognitive bias that causes people to avoid doing something, because they believe that other people are doing it. [9]

Origin

A literal "bandwagon", from which the metaphor is derived.

The phenomenon where ideas become adopted as a result of their popularity has been apparent for some time. However, the metaphorical use of the term bandwagon in reference to this phenomenon began in 1848. [10] A literal "bandwagon" is a wagon that carries a musical ensemble, or band, during a parade, circus, or other entertainment event. [11] [12]

The phrase "jump on the bandwagon" first appeared in American politics in 1848 during the presidential campaign of Zachary Taylor. Dan Rice, a famous and popular circus clown of the time, invited Taylor to join his circus bandwagon. As Taylor gained more recognition and his campaign became more successful, people began saying that Taylor's political opponents ought to "jump on the bandwagon" themselves if they wanted to be associated with such success.

Later, during the time of William Jennings Bryan's 1900 presidential campaign, bandwagons had become standard in campaigns, [13] and the phrase "jump on the bandwagon" was used as a derogatory term[ when? ], implying that people were associating themselves with success without considering that with which they associated themselves.

Despite its emergence in the late 19th century, it was only rather recently that the theoretical background of bandwagon effects has been understood. [12] One of the best-known experiments on the topic is the 1950s' Asch conformity experiment, which illustrates the individual variation in the bandwagon effect. [14] [9] Academic study of the bandwagon effect especially gained interest in the 1980s, as scholars studied the effect of public opinion polls on voter opinions. [10]

Causes and factors

Individuals are highly influenced by the pressure and norms exerted by groups. As an idea or belief increases in popularity, people are more likely to adopt it; when seemingly everyone is doing something, there is an incredible pressure to conform. [1] Individuals' impressions of public opinion or preference can originate from several sources.

Some individual reasons behind the bandwagon effect include:

Another cause can come from distorted perceptions of mass opinion, known as 'false consensus' or 'pluralistic ignorance'.[ failed verification ] In politics, bandwagon effects can also come as result of indirect processes that are mediated by political actors. Perceptions of popular support may affect the choice of activists about which parties or candidates to support by donations or voluntary work in campaigns. [12]

Spread

The bandwagon effect works through a self-reinforcing mechanism, and can spread quickly and on a large-scale through a positive feedback loop, whereby the more who are affected by it, the more likely other people are to be affected by it too. [7] [9]

A new concept that is originally promoted by only a single advocate or a minimal group of advocates can quickly grow and become widely popular, even when sufficient supporting evidence is lacking. What happens is that a new concept gains a small following, which grows until it reaches a critical mass, until for example it begins being covered by mainstream media, at which point a large-scale bandwagon effect begins, which causes more people to support this concept, in increasingly large numbers. This can be seen as a result of the availability cascade, a self-reinforcing process through which a certain belief gains increasing prominence in public discourse. [9]

Real-world examples

In politics

The bandwagon effect can take place in voting: [15] it occurs on an individual scale where a voters opinion on vote preference can be altered due to the rising popularity of a candidate [16] or a policy position. [17] The aim for the change in preference is for the voter to end up picking the "winner's side" in the end. [18] Voters are more so persuaded to do so in elections that are non-private or when the vote is highly publicised. [19]

The bandwagon effect has been applied to situations involving majority opinion, such as political outcomes, where people alter their opinions to the majority view. [20] Such a shift in opinion can occur because individuals draw inferences[ clarification needed ] from the decisions of others, as in an informational cascade. [21]

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. [12]

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. [7]

Financial markets

The bandwagon effect comes about in two ways in financial markets.

First, through price bubbles: these bubbles often happen in financial markets in which the price for a particularly popular security keeps on rising. This occurs when many investors 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 overvalued. [7]

Second is liquidity holes: when unexpected news or events occur, market participants 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 prices, which can lead to increased panic, which further increases uncertainty, and the cycle continues. [7]

Microeconomics

In microeconomics, bandwagon effects may play out in interactions of demand and preference. [22] 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. [4] 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. [7]

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, [23] calls these prevailing practices medical bandwagons, which he defines as "the overwhelming acceptance of unproved but popular [medical] ideas." [10]

Medical bandwagons have led to inappropriate therapies for numerous patients, and have impeded the development of more appropriate treatment. [24]

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: [25]

In sports

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". [26]

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 affects random people that which posts are viewed and shared.[ clarification needed ] [27]

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. [28]

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 ]

Behavior or behaviour is the range of actions and mannerisms made by individuals, organisms, systems or artificial entities in some environment. These systems can include other systems or organisms as well as the inanimate physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary.

In the field of psychology, cognitive dissonance is the perception of contradictory information and the mental toll of it. Relevant items of information include a person's actions, feelings, ideas, beliefs, values, and things in the environment. Cognitive dissonance is typically experienced as psychological stress when persons participate in an action that goes against one or more of those things. According to this theory, when an action or idea is psychologically inconsistent with the other, people do all in their power to change either so that they become consistent. The discomfort is triggered by the person's belief clashing with new information perceived, wherein the individual tries to find a way to resolve the contradiction to reduce their discomfort.

Public opinion, or popular opinion, is the collective opinion on a specific topic or voting intention relevant to society. It is the people's views on matters affecting them. The term originates from France, and first appeared in the 17th century, though writers had identified the importance of the opinion of the people long before this. Prior to the advent of mass media, public fora such as coffee houses and gentlemen's clubs were used as exchanges of opinion and some reputable locations had great influence.

The theory of consumer choice is the branch of microeconomics that relates preferences to consumption expenditures and to consumer demand curves. It analyzes how consumers maximize the desirability of their consumption, by maximizing utility subject to a consumer budget constraint. Factors influencing consumers' evaluation of the utility of goods include: income level, cultural factors, product information and physio-psychological factors.

<span class="mw-page-title-main">Giffen good</span> Product that people consume more of as the price rises

In economics and consumer theory, a Giffen good is a product that people consume more of as the price rises and vice versa—violating the basic law of demand in microeconomics. For any other sort of good, as the price of the good rises, the substitution effect makes consumers purchase less of it, and more of substitute goods; for most goods, the income effect reinforces this decline in demand for the good. But a Giffen good is so strongly an inferior good in the minds of consumers that this contrary income effect more than offsets the substitution effect, and the net effect of the good's price rise is to increase demand for it. This phenomenon is known as the Giffen paradox. A Giffen good is considered to be the opposite of an ordinary good.

<span class="mw-page-title-main">Veblen good</span> Luxury good for which the demand increases as the price increases

A Veblen good is a type of luxury good, named after American economist Thorstein Veblen, for which the demand increases as the price increases, in apparent contradiction of the law of demand, resulting in an upward-sloping demand curve. The higher prices of Veblen goods may make them desirable as a status symbol in the practices of conspicuous consumption and conspicuous leisure. A product may be a Veblen good because it is a positional good, something few others can own.

In social psychology, group polarization refers to the tendency for a group to make decisions that are more extreme than the initial inclination of its members. These more extreme decisions are towards greater risk if individuals' initial tendencies are to be risky and towards greater caution if individuals' initial tendencies are to be cautious. The phenomenon also holds that a group's attitude toward a situation may change in the sense that the individuals' initial attitudes have strengthened and intensified after group discussion, a phenomenon known as attitude polarization.

In psychology, the false consensus effect, also known as consensus bias, is a pervasive cognitive bias that causes people to "see their own behavioral choices and judgments as relatively common and appropriate to existing circumstances". In other words, they assume that their personal qualities, characteristics, beliefs, and actions are relatively widespread through the general population.

Social proof is a psychological and social phenomenon wherein people copy the actions of others in choosing how to behave in a given situation. The term was coined by Robert Cialdini in his 1984 book Influence: Science and Practice.

An information cascade or informational cascade is a phenomenon described in behavioral economics and network theory in which a number of people make the same decision in a sequential fashion. It is similar to, but distinct from herd behavior.

The anchoring effect is a psychological phenomenon in which an individual's judgements or decisions are influenced by a reference point or "anchor" which can be completely irrelevant. Both numeric and non-numeric anchoring have been reported in research. In numeric anchoring, once the value of the anchor is set, subsequent arguments, estimates, etc. made by an individual may change from what they would have otherwise been without the anchor. For example, an individual may be more likely to purchase a car if it is placed alongside a more expensive model. Prices discussed in negotiations that are lower than the anchor may seem reasonable, perhaps even cheap to the buyer, even if said prices are still relatively higher than the actual market value of the car. Another example may be when estimating the orbit of Mars, one might start with the Earth's orbit and then adjust upward until they reach a value that seems reasonable.

<span class="mw-page-title-main">Consumer behaviour</span> Study of individuals, groups, or organisations and all the activities associated with consuming

Consumer behaviour is the study of individuals, groups, or organisations and all the activities associated with the purchase, use and disposal of goods and services. Consumer behaviour consists of how the consumer's emotions, attitudes, and preferences affect buying behaviour. Consumer behaviour emerged in the 1940–1950s as a distinct sub-discipline of marketing, but has become an interdisciplinary social science that blends elements from psychology, sociology, social anthropology, anthropology, ethnography, ethnology, marketing, and economics.

Status quo bias is an emotional bias; a preference for the maintenance of one's current or previous state of affairs, or a preference to not undertake any action to change this current or previous state. The current baseline is taken as a reference point, and any change from that baseline is perceived as a loss or gain. Corresponding to different alternatives, this current baseline or default option is perceived and evaluated by individuals as a positive.

In media studies, mass communication, media psychology, communication theory, and sociology, media influence and themedia effect are topics relating to mass media and media culture's effects on individuals' or audiences' thoughts, attitudes, and behaviors. Through written, televised, or spoken channels, mass media reach large audiences. Mass media's role in shaping modern culture is a central issue for the study of culture.

Herd behavior is the behavior of individuals in a group acting collectively without centralized direction. Herd behavior occurs in animals in herds, packs, bird flocks, fish schools and so on, as well as in humans. Voting, demonstrations, riots, general strikes, sporting events, religious gatherings, everyday decision-making, judgement and opinion-forming, are all forms of human-based herd behavior.

Self-licensing is a term used in social psychology and marketing to describe the subconscious phenomenon whereby increased confidence and security in one's self-image or self-concept tends to make that individual worry less about the consequences of subsequent immoral behavior and, therefore, more likely to make immoral choices and act immorally. In simple terms, self-licensing occurs when people allow themselves to indulge after doing something positive first; for example, drinking a diet soda with a greasy hamburger and fries can lead one to subconsciously discount the negative attributes of the meal's high caloric and cholesterol content.

The default effect, a concept within the study of nudge theory, explains the tendency for an agent to generally accept the default option in a strategic interaction. The default option is the course of action that the agent, or chooser, will obtain if he or she does not specify a particular course of action. The default effect has broad applications for firms attempting to 'nudge' their customers in the direction of the firm's optimal outcome. Experiments and observational studies show that making an option a default increases the likelihood that such an option is chosen. There are two broad classes of defaults: mass defaults and personalised defaults. Setting or changing defaults has been proposed and applied by firms as an effective way of influencing behaviour—for example, with respect to setting air-conditioner temperature settings, giving consent to receive e-mail marketing, or automatic subscription renewals.

The psychology of eating meat is an area of study seeking to illuminate the confluence of morality, emotions, cognition, and personality characteristics in the phenomenon of the consumption of meat. Research into the psychological and cultural factors of meat-eating suggests correlations with masculinity, support for hierarchical values, and reduced openness to experience. Because meat eating is widely practiced but is sometimes associated with ambivalence, it has been used as a case study in moral psychology to illustrate theories of cognitive dissonance and moral disengagement. Research into the consumer psychology of meat is relevant both to meat industry marketing and to advocates of reduced meat consumption.

Authority bias is the tendency to attribute greater accuracy to the opinion of an authority figure and be more influenced by that opinion. An individual is more influenced by the opinion of this authority figure, believing their views to be more credible, and hence place greater emphasis on the authority figure's viewpoint and are more likely to obey them. This concept is considered one of the social cognitive biases or collective cognitive biases.
