The Bandwagon Effect: Definition, Examples, and Effects

Have you ever gotten into a hobby—like pickleball, breadmaking, or nine-step skincare routines—just because it seemed like everyone else was doing it? Even if it's something you're not naturally drawn to, the sudden popularity might leave you wondering what all the hype is about.

Everyone else is doing it, so it must be worth doing, right? It can leave you feeling like if you don't at least give it a try, you'll end up missing out on some important, shared cultural phenomenon.

If you've ever jumped on a trend (whether due to FOMO, peer pressure, or something else), you've experienced an example of what psychologists call the bandwagon effect.

The bandwagon effect refers to the tendency of people to adopt certain behaviors, styles, or attitudes simply because everyone else is doing it. The more people adopt a particular trend, the more likely it becomes that other people will also hop on the bandwagon.

At a Glance

The bandwagon effect is one reason why we often fall for short-lived trends. It can affect our choices—in ways that can be both good and bad. Positive bandwagons might inspire us to adopt healthy behaviors, while negative bandwagons might lead us to try out questionable health advice or spend money on things we don't need. Exploring some bandwagon examples can give some insight into why this happens, and what you can do to avoid it.

The Bandwagon Effect and Cognitive Biases

The bandwagon effect is part of a larger group of cognitive biases or errors in thinking that influence the judgments and decisions that people make. Cognitive biases are often designed to help people think and reason more quickly, but they often introduce miscalculations and mistakes.

Bandwagon Examples

Below are some examples of the Bandwagon Effect:

• Diets: When everyone seems to adopt a particular fad diet, people become more likely to try it themselves.

• Elections: People are more likely to vote for the candidate they think is winning.

• Fashion: Fashion trends seem to be particularly vulnerable to the bandwagon effect. They also tend to be fleeting. Just as one trend takes hold, others quickly become outdated and relegated to the back of our closets.

• Music: As more and more people begin listening to a particular song or musical group, it becomes more likely that other individuals will listen as well.

• Social networks: Trends on social media sites can involve recreating specific types of posts or sharing certain types of content. The bandwagon effect can also influence how posts are shared and interactions within online groups.

Picking up generational slang terms can also be an example of hopping on the bandwagon. If you find yourself using terms like "bet," "rizz," or "bussin'" after spending a few hours on TikTok, it might be due, in part, to the bandwagon effect.

What Impact Does It Have?

The bandwagon effect shows why we shouldn't always let popular opinion dictate what is right. Sometimes things that are good for the majority of people, aren't right for everyone.

Just because wide-leg pants are considered fashionable at the moment, for example, doesn't mean that they are flattering or comfortable for all body types and shapes.

Evaluating yourself based on what is considered popular now can also harm your self-esteem and prevent you from achieving your full potential. Just because you enjoy something that isn't popular or has an interest many others don't seem to share does not mean those activities are not worth pursuing.

The zeitgeist is constantly shifting. What's "in" today can just as easily be "out" tomorrow.

Fashions and pop culture phenomena aren't the only passing trends affected by the bandwagon effect. Research has shown that the effect can also influence the decisions made by doctors, therapists, and other healthcare professionals.

The authors of one study suggest that rush to prescribe ketamine to treat depression without fully understanding how or why it works is an example of a current psychiatric fad influenced by the bandwagon effect.

Factors that Influence the Bandwagon Effect

So, why exactly does the bandwagon effect occur? Individuals are highly influenced by the pressure and norms exerted by groups. When it seems like the majority of the group is doing a certain thing, not doing that thing becomes increasingly difficult.

It's a natural tendency for people to follow along with the rest of the group. Sometimes, we do it because we feel pressured. In other cases, we compare ourselves to others and then try to change to be more like the group. Hopping on trends can even play a role in helping us bond with others.

This pressure to fit in can impact many different aspects of behavior, from what people wear to who they vote for in political elections.

Some of the factors that can influence the bandwagon effect include:

• Heuristics: The human brain is hard-wired to use heuristics, or mental shortcuts, to help make decisions faster and more efficiently. When you are making choices, you are naturally inclined to rely on rules of thumb that help speed up your decisions. These heuristics can be influenced by what you see everyone else doing.

• Groupthink: The bandwagon effect is essentially a type of groupthink. As more people adopt a particular fad or trend, the more likely it becomes that other people will also "hop on the bandwagon." When it seems that everyone is doing something, there is a tremendous pressure to conform, which is perhaps why bandwagon behaviors tend to form so easily.

• A Desire To Be Right: People want to be right. They want to be part of the winning side. Part of the reason people conform is that they look to other people in their social group for information about what is right or acceptable.

If it seems like everyone else is doing something, then people are left with the impression that it is the correct thing to do.

• A Need to Be Included: Fear of exclusion also plays a role in the bandwagon effect. People generally do not want to be the odd one out, so going along with what the rest of the group is doing is a way to ensure inclusion and social acceptance.

The need to belong pressures people to adopt the norms and attitudes of the majority to gain acceptance and approval from the group.

While the bandwagon effect can be very powerful and leads to the ready formation of trends, these behaviors also tend to be somewhat fragile. People jump on the bandwagon quickly, but they also jump off it just as fast. This is perhaps why trends tend to be so fleeting.

Risks of the Bandwagon Effect

The impact of these bandwagon trends is often relatively harmless, such as in fashion, music, or pop culture fads. Sometimes they can be far more dangerous.

When certain ideas begin to take hold, such as particular attitudes toward health issues, bandwagon beliefs can have serious and damaging consequences.

Some negative or even dangerous examples of the bandwagon effect:

• Individuals who were influenced by the anti-vaccination movement, for example, became less likely to get routine childhood immunizations for their children. This large-scale avoidance of vaccinations has been linked to a recent measles outbreak.

• Researchers have found that when people learn that a particular candidate is leading in the polls, they are more likely to change their vote to conform to the winning side. In one study carried out during the 1992 U.S. presidential election, students who learned that Bill Clinton was leading the race in some polls switched their intended vote from Bush to Clinton.

While the bandwagon effect can have potentially dangerous consequences in some cases, it can also lead to adopting healthy behaviors. If it seems that the majority of people reject unhealthy behaviors (such as smoking) and embrace healthy choices (such as exercising and working out), people may then become more likely to avoid risky choices and engage in healthy actions.

How to Avoid the Bandwagon Effect

Is there anything you can do to guard against the bandwagon effect? Researchers suggest a few methods that can help:

• Be Wary of Simple Solutions: Bandwagons often offer simple solutions for complex problems. They often claim to work for everyone all of the time and are often touted by charismatic gurus who may lack the necessary expertise and experience to back up their claims.

• Seek Diverse Information: Don't listen to a single source when evaluating information. Seek out a range of data and opinions, including alternative or contrary views.

• Recognize Cognitive Dissonance: Recognizing that you've fallen prey to the bandwagon effect can be rough. Sometimes, you might feel a bit foolish that you jumped on a short-lived trend. Or you might feel duped because you spent money on products or services that made false promises. In either case, letting go once the trend has lost appeal or popularity isn't always easy.

You might have mixed feelings about letting go of something that feels familiar and comfortable. Or it might seem like you need to stick with it since you've already invested so much into it—an example of the sunk costs fallacy.

When letting go of a long-held practice or belief that was adopted due to the bandwagon effect, it can be helpful to remember that you're likely to experience feelings of discomfort and cognitive dissonance when change happens.

Give yourself time to adapt to changes—and be careful to avoid replacing old gimmicks with new ones.

• Look for Evidence: Bandwagons often rely on limited or anecdotal evidence. Health trends that spread via social media sites like TikTok are good examples. Their sudden, widespread adoption is often backed up by nothing more than the testimonials.

You should view such practices skeptically and look for legitimate, evidence-based information that might support or dispute such claims. Or, at the very least, ask your doctor before you try it.
