The more people understand how cognitive dissonance operates and how we are all susceptible to it, the more helpful it is in understanding our own behavior. So, to know that the minute we make a decision—whether it's about a car or partner or a house or how to live with COVID-19—any time we make a decision, we're going to be motivated to throw support for that decision and ignore evidence that we're wrong. The moment that we understand that gives us a whole new toolbox of ways of dealing with our own beliefs and attitudes.
