Recently I have been thinking a lot about the way we think. To each of us, it feels as though our thinking and our thought process is logical, that our assumptions about the world are sound and built on good evidence, and that we might have a few complex technical facts wrong, but our judgments are not influenced by bias or prejudice. We feel that we take into consideration wide ranges of data when making decisions, and we do not feel as though our decisions and opinions are influenced by meaningless information and chance.
However, science tells us that our brains often make mistakes, and that many of those mistakes are systematic. Also, we know people in our own lives who display wonderful thinking errors, such as close-mindedness, gullibility, and arrogance. We should be more ready to accept that our thinking isn’t any different from the minds of people in scientific studies that show the brain’s capacity to traverse off course or that we are really any different from the person we complain about for being biased or unfair in their thinking about something or someone we we care about.
What can make this process hard is the mind itself. Our brains are experts at creating logical narratives, including about themselves. We are great at explaining why we did what we did, why we believe what we believe, and why our reasoning is correct. Scientists call this motivated reasoning.
Dale Carnegie has a great explanation of it in his book How to Win Friends and Influence People, “We like to continue to believe what we have been accustomed to accept as true, and the resentment aroused when doubt is cast upon any of our assumptions leads us to seek every manner of excuse for clinging to it. The result is that most of our so-called reasoning consists in finding arguments for going on believing as we already do.”
Very often, when confronted with new information that doesn’t align with what we already believe, doesn’t align with our own self-interest, or that challenges our identity in one way or another, we don’t update our thinking but instead explain away or ignore the new information. Even for very small thing (Carnegie uses the pronunciation of Epictetus as an example) we may ignore convention and evidence and back our beliefs in outdated and out of context examples that seem to support us.
In my own life I try to remember this, and whether it is my rationalization of why it is OK that I went for a workout rather than doing dishes, or my self-talk about how great a new business idea is, or me rationalizing buying that sushi at the store when I was hungry while grocery shopping, I try to ask myself if my thoughts and decisions are influenced by motivated reasoning. This doesn’t always change my behavior, but it does help me recognize that I might be trying to fool myself. It helps me see that I am no better than anyone else when it comes to making up reasons to support all the things that I want. When I see this in other people, I am able to pull forward examples from my own life of me doing the same thing, and I can approach others with more generosity and hopefully find a more constructive way of addressing their behavior and thought process. At an individual level this won’t change the world, but on the margins we should try to reduce our motivated reasoning, as hard as it may be, and slowly encourage those around us to do the same.
