Les gens recherchent la cohérence entre leurs propres attentes personnelles de la vie, comme vouloir apprendre de nouvelles matières, et la réalité, c’est-à-dire aller en classe. Dans cet exercice d’équilibriste, les deux sont alignés et l’élève se sent à l’aise en tant qu’élève fonctionnel. Cependant, les croyances et les actions de la personne peuvent parfois être incohérentes. Par exemple, son groupe d’étude prévoit de se réunir au pub local pour une séance de répétition sérieuse en classe. Bien qu’il s’engage à être studieux et que trop boire interfère avec cette croyance, il commande trop de pintes, ce qui contredit ses attentes savantes.

Cette dernière situation est un exemple de dissonance cognitive, c’est-à-dire un état de détresse mentale lié à des croyances contradictoires. Un tel conflit psychologique produit un malaise et, par conséquent, l’individu peut réagir de plusieurs façons pour atténuer la dissonance.

Premièrement, il pourrait changer son comportement : la prochaine fois, il ne prendra qu’une seule pinte.

Deuxièmement, il pourrait changer ses croyances : il pourrait se convaincre qu’étudier pour l’examen n’était vraiment pas si important.

Troisièmement, il pouvait justifier ses actions : il avait vraiment besoin d’une pause.

Et quatrièmement, il pourrait ignorer ou nier l’information : il pourrait décider de penser que la bière n’entraverait vraiment pas sa concentration.

En fin de compte, les individus réagissent pour aligner leurs comportements, leurs croyances et leurs attitudes et revenir à un état où ils se sentent mieux dans leur peau.

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris &amp; Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, &amp; Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our self-esteem or positive self-image. Psychologist Leon Festinger (1957) defined&nbsp;cognitive dissonance&nbsp;as psychological discomfort arising from holding two or more inconsistent attitudes, behaviors, or cognitions (thoughts, beliefs, or opinions). Festinger&rsquo;s theory of cognitive dissonance states that when we experience a conflict in our behaviors, attitudes, or beliefs that runs counter to our positive self-perceptions, we experience psychological discomfort (dissonance). For example, if you believe smoking is bad for your health but you continue to smoke, you experience conflict between your belief and behavior.

Later research documented that only conflicting cognitions that threaten individuals&rsquo; positive self-image cause dissonance (Greenwald &amp; Ronis, 1978). Additional research found that dissonance is not only psychologically uncomfortable but also can cause physiological arousal (Croyle &amp; Cooper, 1983) and activate regions of the brain important in emotions and cognitive functioning (van Veen, Krug, Schooler, &amp; Carter, 2009). When we experience cognitive dissonance, we are motivated to decrease it because it is psychologically, physically, and mentally uncomfortable. We can reduce&nbsp;cognitive dissonance&nbsp;by bringing our cognitions, attitudes, and behaviors in line&mdash;that is, making them harmonious. This can be done in different ways, such as:

<ul>
	<li>changing our discrepant behavior (e.g., stop smoking),</li>
	<li>changing our cognitions through rationalization or denial (e.g., telling ourselves that health risks can be reduced by smoking filtered cigarettes),</li>
	<li>adding a new cognition (e.g., &ldquo;Smoking suppresses my appetite so I don&rsquo;t become overweight, which is good for my health.&rdquo;).</li>
</ul>

More Examples, Please.

A classic example of cognitive dissonance is John, a 20-year-old who enlists in the military. During boot camp he is awakened at 5:00 a.m., is chronically sleep deprived, yelled at, covered in sand flea bites, physically bruised and battered, and mentally exhausted. It gets worse. Recruits that make it to week 11 of boot camp have to do 54 hours of continuous training.

Not surprisingly, John is miserable. No one likes to be miserable. In this type of situation, people can change their beliefs, their attitudes, or their behaviors. The last option, a change of behaviors, is not available to John. He has signed on to the military for four years, and he cannot legally leave.

If John keeps thinking about how miserable he is, it is going to be a very long four years. He will be in a constant state of cognitive dissonance. As an alternative to this misery, John can change his beliefs or attitudes. He can tell himself, &ldquo;I am becoming stronger, healthier, and sharper. I am learning discipline and how to defend myself and my country. What I am doing is really important.&rdquo; If this is his belief, he will realize that he is becoming stronger through his challenges. He then will feel better and not experience cognitive dissonance, which is an uncomfortable state.

The Effect of Initiation

The military example demonstrates the observation that a difficult&nbsp;initiation&nbsp;into a group influences us to like the group&nbsp;more, due to the justification of effort. We do not want to have wasted time and effort to join a group that we eventually leave. A classic experiment by Aronson and Mills (1959) demonstrated this justification of effort effect. College students volunteered to join a campus group that would meet regularly to discuss the psychology of sex. Participants were randomly assigned to one of three conditions: no initiation, an easy initiation, and a difficult initiation into the group. After participating in the first discussion, which was deliberately made very boring, participants rated how much they liked the group. Participants who underwent a difficult initiation process to join the group rated the group more favorably than did participants with an easy initiation or no initiation.

Similar effects can be seen in a more recent study of how student effort affects course evaluations. Heckert, Latier, Ringwald-Burton, and Drazen (2006) surveyed 463 undergraduates enrolled in courses at a midwestern university about the amount of effort that their courses required of them. In addition, the students were also asked to evaluate various aspects of the course. Given what you&rsquo;ve just read, it will come as no surprise that those courses that were associated with the highest level of effort were evaluated as being more valuable than those that did not. Furthermore, students indicated that they learned more in courses that required more effort, regardless of the grades that they received in those courses (Heckert et al., 2006).

Besides the classic military example and group initiation, can you think of other examples of&nbsp;cognitive dissonance? Here is one: Marco and Maria live in Fairfield County, Connecticut, which is one of the wealthiest areas in the United States and has a very high cost of living. Marco telecommutes from home and Maria does not work outside of the home. They rent a very small house for more than $3000 a month. Maria shops at consignment stores for clothes and economizes where she can. They complain that they never have any money and that they cannot buy anything new. When asked why they do not move to a less expensive location, since Marco telecommutes, they respond that Fairfield County is beautiful, they love the beaches, and they feel comfortable there. How does the theory of cognitive dissonance apply to Marco and Maria&rsquo;s choices?

cognitive dissonance and self-image

Cognitive dissonance is psychological discomfort that happens when a person holds two or more inconsistent thoughts, beliefs, attitudes, or behaviors. Social psychologists note that this conflict is especially likely to matter when it threatens a person's positive self-image. People often want to feel good about themselves, and a threat to self-esteem can shape what they do and what they believe.

Psychologist Leon Festinger defined cognitive dissonance in 1957. His theory says that when behavior, attitudes, and beliefs clash with a person's self-view, the result is uncomfortable. A common example is knowing that smoking is bad for health but continuing to smoke. Later research found that not every conflict causes dissonance. The conflict is most likely to matter when it challenges a person's positive view of self.

Cognitive dissonance is not only a mental feeling. Research has shown that it can also cause physical arousal and activate brain regions tied to emotion and thinking. Because the state is psychologically, physically, and mentally uncomfortable, people are motivated to reduce it. They can do that by changing the behavior, changing the belief through rationalization or denial, or adding a new belief that makes the situation feel more reasonable.

A military boot camp example shows how dissonance can work in real life. John, a 20-year-old recruit, is sleep deprived, exhausted, and miserable during training. He cannot simply leave, so changing his behavior is not an option. Instead, he can reduce the discomfort by changing his attitude and telling himself that he is becoming stronger, healthier, sharper, and more disciplined, and that he is helping defend his country.

The same idea helps explain the justification of effort effect. A difficult initiation into a group can make people like the group more because they do not want to feel that their effort was wasted. In a classic study, college students joined a campus group that would discuss the psychology of sex. Some had no initiation, some had an easy one, and some had a difficult one. After a deliberately boring first discussion, the students who faced the difficult initiation rated the group more favorably.

Later research found a similar pattern in college courses. Students who said their courses required more effort often rated those courses as more valuable. They also reported learning more, even when their grades were the same. The concept also fits everyday choices. Marco and Maria pay high rent in Fairfield County, Connecticut, and say they have little money, yet they stay because they love the area and feel comfortable there. Their explanation helps reduce the tension between their costs and their choice to remain.

attitudes

Attitude Components in Everyday Life

Attitude is our evaluation of a person, an idea, or an object. People hold attitudes about many things. These can include products from the supermarket, people around the world, and political policies. Attitudes are usually favorable or unfavorable, meaning positive or negative. Attitudes also have three parts. The affective component is the feeling part. The behavioral component is the effect the attitude has on behavior. The cognitive component includes belief and knowledge. For example, a...

routes of persuasion

Central and Peripheral Persuasion Paths

Persuasion changes attitudes, beliefs, and behaviors through communication. People often meet persuasion from outside sources in everyday life. The topic has been studied closely in social psychology, especially through Carl Hovland’s work during World War II and later at Yale University. His work led to the Yale attitude change approach, which explains when people are likely to change their attitudes. The Yale attitude change approach shows that persuasion depends on the source, the message,...

persuasion strategies

How Small Requests Influence Bigger Yeses

Persuasion strategies can shape what people buy and how they think or act. Researchers have tested these methods in many settings, including sales and behavior change. Two well-known examples are the foot-in-the-door technique and the door-in-the-face technique. The foot-in-the-door technique starts with a small request. If someone agrees to that first request, they are more likely to agree to a larger request later. This works through consistency, which is the tendency to stay in line with...

social proof

Social Proof in Everyday Choices

Social proof is a persuasion tactic that shapes everyday choices through comparison and conformity. People often look at what others are doing and adjust their own actions to match the group. This response can happen quickly, especially when a behavior seems popular or widely accepted. A clear example comes from television laugh tracks. Fullery and Skeffington (1974) found that adding group laughter to material made people rate it as funnier, even when the content was not actually funny. In...
