Mistakes Were Made (But Not By Me)

I finished reading Mistakes Were Made (But Not By Me) by Carol Tavris and Elliot Aronson this past weekend and all I can say is, “Wow”. This was an awesome book, quite the eye-opener. The premise, which nobody can deny, is that our biases affect how we look at new information. We see this all the time in the nutrition world, where those that have staked their livelihoods on a specific dietary regimen do all sorts of mental gymnastics to explain away new data that goes against their existing ideas. And it’s not just the “low fat” camp that does it.

Tavris and Aronson discuss all types of dissonance. For instance, one that I’ve pointed out to people many times is the area of politics. Once you associate yourself with a particular party, generally Democrat or Republican, you automatically and unconsciously, discount the views of the other party as “them” and give extra weight to those of “your” party as “us”. One particular study showed that Republicans/Democrats rated a welfare plan proposed by “the other party” when they thought it came from a member of their own party. Once someone aligns with a group, opinions of that group are automatically rated higher, regardless of their logic and regardless of the logic of opinions from opposing groups. We all know those people that would vote for Charles Manson so long as he was running for the right party.

Another example was that the interrogation techniques used by many police departments result in innocent people confessing to crimes they didn’t commit. Even when these convictions are later overturned on DNA evidence, the officers and prosecutors refuse to admit that they could have been wrong. They explain away the DNA evidence and assume the person is guilty of something.

The bottom line is that we all have areas of bias and blindness. It is inevitable as a higher thinking being. The key is to understand your biases (for example, I’m biased against low fat diets) and understand how they affect new information that comes your way. It affects politics, nutrition, marriage, friendships, family relationships, international relations, everything. I highly recommend this book.
