“We now realize,” write Kevin Simler and Robin Hanson in their book The Elephant in the Brain, “that our brains aren’t just hapless and quirky–they’re devious. They intentionally hide information from us, helping us fabricate plausible pro-social motives to act as cover stories for our less savory agendas. As Trivers puts it: “At ever single state [of processing information]–from its biased arrival, to its biased encoding, to organizing it around false logic, to misremembering and then misrepresenting it to others–the mind continually acts to distort information flow in favor of the usual goal of appearing better than one really is.”
Recently I have been pretty fascinated by the idea that our minds don’t do a good job of perceiving reality. The quote above shows many of the points where our minds build a false sense of reality for us and where our perceptions and understanding can go astray. It is tempting to believe that we observe and recognize an objective picture of the world, but there are simply too many points where our mental conceptualization of the world can deviate from an objective reality (if that objective reality ever even exists).
What I have taken away from discussions and books focused on the way we think and the mistakes our brain can make is that we cannot always trust our mind. We won’t always remember things correctly and we won’t always see things as clearly as we believe. What we believe to be best and correct about the world may not be accurate. In that sense, we should doubt our beliefs and the beliefs of others constantly. We should develop processes and systems for identifying information that is reasonable and question information that aligns with our prior beliefs as much as information that contradicts our prior beliefs. We should identify key principles that are most important to us, and focus on those, rather than focus on specific and particular instances that we try to understand by filling in answers from generalizations.
A fear that I have is that as we come to doubt the information around us and the perceptions of our minds, we will begin to doubt institutional structures that help us with the flow of information. We should be continually thinking of ways to strengthen institutions that can help us navigate a complex world. At the moment, one of the things I think we are seeing across the globe is that as we doubt information, we doubt institutions which have been valuable in helping human societies advance. We need to find ways to make institutional knowledge more trustworthy and clear so that we can develop institutions which have incentives to provide the most reasonable, clear, and accurate information possible so that we can overcome the biases and misconceptions of the mind.
