Bobby Azarian is a cognitive neuroscientist and science journalist whose articles I have found interesting and useful. Recently, I came across a couple of his articles dealing with what appears to be a growing popularity of ignorance and increasing stupidity that Azarian considers and existential threat to modern society.
A neuroscientist explains the problem of ignorance and how we can fight it
"Being ignorant about a particular topic isn’t shameful. None of us know everything — that’s an impossible task. Ignorance does not come from a lack of education, but an unwillingness to seek education. Ignorance is a consequence of refusing to change your beliefs when reality is constantly contradicting them."
Cognitive neuroscientist explains why stupidity is an existential threat to America
"Stupidity is a consequence of a failure to be aware of one’s own limitations, and this type of cognitive failure has a scientific name: the Dunning-Kruger effect."
These two subjects are of much interest to me, considering the proliferation of conspiracy theories that people are using as the basis for decision making and the almost gleeful celebration of ignorance and near rejection of education as "elitist" in some quarters. Couple that with a growing population of those rejecting expert opinion in favor of their own unearned expertise and I think that we do have a growing threat to our future.
We are all ignorant to a degree relevant to the the subject under consideration, but many people seem to no longer question anything that fits with the model they live by regardless of how irrational or ridiculous it might be. If it feeds into what they want to believe, it is uncommon to see the unbelievable believed. At the same time we see a growing number of people that assume subject matter expertise of subjects they don't seem to know much or anything about. How can we, as a nation build on a foundation like that? We lose progress and actually begin to regress culturally, educationally, scientifically as well as competitively on the international field. There appears to be no upside to ignorant and stupid outside of politics.
I'm including a link to a review explaining the Dunning-Kruger effect in more detail, but essentially, it is that many do not know what they do not know.
