It has happened again. A new paper, based on a tranche of unsealed historical documents, casts serious doubt on a piece of social psychology research from the mid-20th Century. Shocker!
This time it’s about some of the fundamental inspirations for the idea of cognitive dissonance—the idea that holding contradictory views in one’s head creates discomfort and a need to change one of the beliefs. So what does the new historical research say? What about all the studies that claim to find evidence for cognitive dissonance—surely the whole thing isn’t a load of nonsense? Listen to this episode to find out.
