Leon Festinger, the social psychologist that coined the term “cognitive dissonance” in 1957, makes this observation: “The more committed we are to a belief , the harder it is to relinquish, even in the face of overwhelming contradictory evidence. Instead of acknowledging error in judgment and abandoning the opinion, we tend to develop a new attitude or belief that will justify retaining it,” writes Robert Burton in On Being Certain.
In other words, a mindset of certainty can leave us unteachable, arrogant and stuck. It impedes growth and personal development. We need to spend more time thinking than rationalizing.
