Mistakes were made (but not by me)

High Quality Content by WIKIPEDIA articles! Mistakes were made is a non-fiction book by social psychologists Carol Tavris and Elliot Aronson, first published in 2007. It deals with cognitive dissonance, self-serving bias and other cognitive biases, using these psychological theories to illustrate how the perpetrators of hurtful acts justify and rationalize their behavior. It describes a positive feedback loop of action and self-deception by which slight differences between people's attitudes become polarised.
