great read: MISTAKES WERE MADE (but not by me)

Do you sometimes wonder why someone digs in their heels and refuses to change their mind even when it makes no sense?  Do you sometimes see people make illogical or irrational decisions which they cling to in the face of all evidence?  Then you like me need answers.  This is one of my all-time favourite books.

"Mistakes were Made (but not my me)" explains the power of self-justification to make rational that which is not rational.  In respect of some decisions, we make an emotional decision, we will then use our cognitive powers to rationalise this decision.  The authors describe how we make a decision based on how we feel and then use our mental tools to support it.

The book starts with the work of Leon Festinger and his research into doomsday cults (where the spaceships don't come on the scheduled date!). It examines different areas of human experience: criminal work / relationships / politics / etc.  Tavris and Aronson explain how we can start down a path from which the return journey is all uphill. From how people interact within a marriage to historical examples from Nazi Germany, the power of our minds to convince us is astonishing.

In terms of understanding others decision-making, the authors explain how we each essentially want to think of ourselves as good people.  We may do things that are wrong or inflict pain on others but we are good people.  The gap between our belief in our own goodness and the wrongness of our actions leads to cognitive dissonance.  We desperately need to resolve this dissonance. We are good people, therefore we must have a good reason for acting in that way. It can't be that we would do something wrong, or behave badly? there must be a reason.  

How do we do resolve the cognitive dissonance?  we convince ourselves that there is a justification for our behaviour.  Our memory becomes a "self-justifying historian" who is able to provide the proof that the person we have harmed is bad / wrong / evil / not human.

It can be uncomfortable confronting the truth about some of our strongly held beliefs and justifications. However, if we can understand how cognitive dissonance drives our decisions and beliefs, we have the opportunity to be free of it and, importantly, to let go of the need to be right.
