Huh. Some of the books will be ones about doctors, like https://www.amazon.com/Doctors-Think-Jerome-Groopman-2007-03..., which you have to read to find how they talk about cognitive dissonance. Others will be about cognitive dissonance in general, like https://www.amazon.com/Mistakes-Were-Made-but-Third/dp/03583..., which you have to read to find how they use the medical profession as starring examples.

Sorry for not having given you an easier cookie crumb.
