Changing Someone’s Mind
Changing someone’s mind is rarely about proving that you are right. In fact, the harder you try to convince someone that they are wrong, the more likely they are to dig in.

One of the most revealing examples of this phenomenon comes from a bizarre episode in the 1950s. A Chicago woman named Marian Keech claimed to have received messages from extraterrestrial beings warning that the world would be destroyed by a catastrophic flood on December 21, 1954. A small group of followers, known as the Seekers, believed her. Some abandoned their jobs, gave away possessions and separated themselves from their families in preparation for the end of the world. Three psychologists, Leon Festinger, Henry Riecken and Stanley Schachter, infiltrated the group to observe what would happen when the prophecy failed. Then December 21 arrived. Nothing happened. There was no flood. The world continued its thoroughly unimpressive habit of existing. You might expect the group to admit that they had been wrong. Instead, something much more interesting happened. Keech announced that the group’s faith had been so powerful that God had decided to spare the Earth. The failed prophecy did not destroy the belief. It strengthened it. The psychologists were witnessing what Festinger would later describe as cognitive dissonance, the uncomfortable tension that occurs when reality conflicts with something we strongly believe. The Seekers had invested too much in their prediction. They had sacrificed possessions, relationships and reputations. Admitting they were wrong would not simply mean
