The Dangers of the Dunning-Krueger Effect

There have been previous posts on the Dunning-Krueger Effect, and many future posts can be assumed. The reason is that the Dunning-Krueger Effect is especially relevant to today’s problems. Remember that there are two components of the Dunning Krueger effect. The first component summarizes the large body of research showing that the more people think they know about a topic, the less they actually know. The second component is that people who are knowledgeable about a topic are aware of the gaps in their knowledge.

There are unfortunate fallouts to this effect. People who know little or nothing can sound confident and fool some people into thinking that they know more than true experts on the topic. System 1 processing, which is fast and carries emotions facilitates this effect. True knowledge requires System 2 processing, which regards thinking based on facts rather than beliefs.

Einstein wrote, “As a human being one has been endowed with just enough intelligence to be able to see clearly how utterly inadequate that intelligence is when confronted with what exists.” Einstein was writing from his personal perspective as a human being. Unfortunately, too many human beings remain ignorant of their ignorance and believe and express thoughts that are divorced from facts and critical thinking.

And such people have elected a President, who like them does not believe in facts, and ignores facts from a renowned intelligence establishment. When facts contradict his beliefs he attacks those facts as misinformation and the people and the institutions who have found the facts as his personal enemies. In doing so he is attacking essential elements of U.S. democracy and unfortunately is being aided and abetted by a major political party.

As has been mentioned in many previous posts, System 2 processing is critical to building a cognitive reserve. Autopsies have revealed patients who had the defining characteristics of Alzheimer’s, amyloid plaque and neurofibrillary tangles, yet had no cognitive or behavioral signs of Alzheimers. The explanation offered for these people is that they had build up a cognitive reserve.
