In Robert Cialdini’s book “Influence: the psychology of persuasion”, he recounts how during the Korean War, Chinese captors were able to get American POW’s to inform on each other. There are, however, no footnotes showing source materials.
They started out by getting the Americans to make easy, small easy negative comments about the US like, “America is not perfect.” Then, over time, ask them to say increasingly negative things. Eventually, relying on the alleged human need to be consistent, the Chinese could get the Americans to inform on each other.
I’m not doubting the conclusions, I just want to know if these stories true. Is there any evidence of this episode?
