The Role of Cognitive Dissonance in the Pandemic

"​The minute we make any decision--I think COVID-19 is serious; no, I’m sure it is a hoax—we begin to justify the wisdom of our choice and find reasons to dismiss the alternative."

"Members of Heaven’s Gate, a religious cult, believed that as the Hale-Bopp comet passed by Earth in 1997, a spaceship would be traveling in its wake—ready to take true believers aboard. Several members of the group bought an expensive, high-powered telescope so that they might get a clearer view of the comet. They quickly brought it back and asked for a refund. When the manager asked why, they complained that the telescope was defective, that it didn’t show the spaceship following the comet. A short time later, believing that they would be rescued once they had shed their “earthly containers” (their bodies), all 39 members killed themselves.

Heaven’s Gate followers had a tragically misguided conviction, but it is an example, albeit extreme, of cognitive dissonance, the motivational mechanism that underlies the reluctance to admit mistakes or accept scientific findings—even when those findings can save our lives. This dynamic is playing out during the pandemic among the many people who refuse to wear masks or practice social distancing. Human beings are deeply unwilling to change their minds. And when the facts clash with their preexisting convictions, some people would sooner jeopardize their health and everyone else’s than accept new information or admit to being wrong.

Cognitive dissonance, coined by Leon Festinger in the 1950s, describes the discomfort people feel when two cognitions, or a cognition and a behavior, contradict each other. I smoke is dissonant with the knowledge that Smoking can kill me. To reduce that dissonance, the smoker must either quit—or justify smoking (“It keeps me thin, and being overweight is a health risk too, you know”). At its core, Festinger’s theory is about how people strive to make sense out of contradictory ideas and lead lives that are, at least in their own minds, consistent and meaningful.  

One of us (Aronson), who was a protégé of Festinger in the mid-’50s, advanced cognitive-dissonance theory by demonstrating the powerful, yet nonobvious, role it plays when the concept of self is involved. Dissonance is most painful when evidence strikes at the heart of how we see ourselves—when it threatens our belief that we are kind, ethical, competent, or smart. The minute we make any decision--I’ll buy this car; I will vote for this candidate; I think COVID-19 is serious; no, I’m sure it is a hoax—we will begin to justify the wisdom of our choice and find reasons to dismiss the alternative. Before long, any ambivalence we might have felt at the time of the original decision will have morphed into certainty. As people justify each step taken after the original decision, they will find it harder to admit they were wrong at the outset. Especially when the end result proves self-defeating, wrongheaded, or harmful.

​The theory inspired more than 3,000 experiments that have transformed psychologists’ understanding of how the human mind works. One of Aronson’s most famous experiments showed that people who had to go through an unpleasant, embarrassing process in order to be admitted to a discussion group (designed to consist of boring, pompous participants) later reported liking that group far better than those who were allowed to join after putting in little or no effort. Going through hell and high water to attain something that turns out to be boring, vexatious, or a waste of time creates dissonance: I’m smart, so how did I end up in this stupid group?"
