Leon Festinger studied a cult that believed the world would end in a flood, but members would be saved by aliens. When the prophecy failed to occur, some members left but others became even more devoted. This showed that when beliefs are contradicted, people can react differently. Cognitive dissonance is the uncomfortable feeling of holding conflicting beliefs or attitudes, or participating in contradictory behaviors. To reduce it, people will change their thoughts or actions to align with what they believe. The document suggests that seeking out alternative perspectives when experiencing cognitive dissonance can help managers adapt, broaden their views, and find better solutions.
