More Information Can Make the World More Confusing

“In my experience,” writes Mary Roach in Spook, “the most staunchly held views are based on ignorance or accepted dogma, not carefully considered accumulations of facts. The more you expose the intricacies and realities of the situation, the less clear-cut things become.”
This quote from Mary Roach is something I have experienced in my own life over and over. I have met many people with very strong views about subjects, and they very often oversimplify an issue and reduce arguments against their position to a straw man. Rather than carefully considering whether their opinions and perspectives are valid, they dismiss arguments against their favored position without real thought. And to be fair, this is something I have even caught myself doing.
I generally seem to be one of those people who can talk about challenging subjects with just about anyone. I think the reason why I am able to talk to people about difficult topics is because I always try to understand how reach the perspective they hold. I also try hard to understand why I hold my own opinions, and I try not to reduce either my own or another person’s opinion to a simple right or wrong morality judgment. I think we come to our opinions through many convoluted paths, and straw-manning an argument does an injustice to the opinions and views of others.
At the same time, I have noticed that those who hold the most oversimplified beliefs do so in a dogmatic manner, as Roach suggested. They may be able to consider facts and go through deeper considerations, but they ultimately fall back on simple dogma, rather than live with the complex cognitive dissonance required to accept that you believe one thing in general, but cannot always rely on that one thing to explain the particulars. Personally, I have found that I can have conversations with these people, but that I feel frustrated when they then turn around and post things on social media that are reductive and ignore the complex perspectives we previously talked through.
Like Roach, I find that those with more detailed and nuanced views, built out of an accumulation of facts, generally are less emotionally invested in a given topic. Perhaps it is a lack of passion for a topic which allowed them to look at facts in such detail, rather than adopting a favored view and immediately dismissing anything that doesn’t align with that view.
Ultimately, I think much of this behavior can be understood by reading Kevin Simler and Robin Hanson’s book The Elephant in the Brain. We are all smart and capable of self-deception in order to more strongly believe the thing we want to believe. Over simplified dogmas simply help us do that better. I think we are often signaling our loyalty to a group or signaling some characteristic that we think is important when we make reductive and dogmatic statements. We recognize what identity we wish to hold and what is in our self-interest, and we act our part, adopt the right beliefs, and signal to others that we are part of the right in-group. In this way, the dogma is a feature and not a bug.
