When You Need It To Be True

This Hidden Brain episode explores cognitive dissonance, the mental discomfort experienced when beliefs clash with reality. It uses two parallel narratives: the story of Dorothy Martin's followers who believed in an impending flood and awaited alien rescue, illustrating how commitment to a belief can lead to rationalization; and Liz's experience with an online romance scammer, highlighting how strong desires can blind individuals to obvious red flags. The episode details how both groups, despite facing contradictory evidence, reinforced their beliefs through various rationalizations. The episode concludes by emphasizing the pain and difficulty involved in confronting deeply held beliefs, even when faced with undeniable proof of their falsity. Liz's experience serves as a cautionary tale about the power of wishful thinking and the importance of critical thinking in relationships.
