Availability Heuristic and Groupthink Meet the Dunning-Kruger Effect
There may be no more combustible combination in modern public discourse than the availability heuristic, groupthink and the Dunning-Kruger effect operating simultaneously.
The availability heuristic is our tendency to judge what is true, common or important according to whatever examples come most readily to mind. See something repeatedly on television or social media and suddenly it feels ubiquitous. Repetition begins masquerading as evidence.
Then comes groupthink. Once enough people within your social, political or professional tribe accept a proposition, questioning it becomes increasingly uncomfortable. Consensus becomes confused with proof. People begin policing themselves because nobody wants to be the heretic at the dinner table, newsroom, faculty lounge or online community.
Now introduce the Dunning-Kruger effect, the tendency associated with limited competence sometimes producing inflated confidence because the person lacks enough knowledge to recognize the limits of his own understanding.
And behold the modern internet.
A person encounters the same proposition repeatedly. Availability tells him it must be important. Everyone around him agrees. Groupthink tells him it must be correct. He possesses enough superficial information to feel knowledgeable but perhaps not enough to appreciate the complexity of the subject. Confidence consequently outruns competence.
The result can be astonishing.
People become absolutely certain about subjects they began studying fifteen minutes ago. They repeat conclusions because everyone they follow repeats them. Contradictory evidence becomes threatening rather than interesting. Questions themselves become suspicious.
This is why intellectual discipline matters more than ever.
Ask: How do I know this? What evidence would prove me wrong? Am I repeating something because I investigated it or because I keep hearing it?
The dangerous mind is not necessarily the uninformed mind.
It is the uninformed mind convinced that further inquiry is unnecessary.
==========================
Merle Haggard’s “Big City” is pure working-man country, a declaration of independence from the grind, bureaucracy and suffocating machinery of modern life. Released in 1981, Haggard sings for anyone who has ever wanted to collect what he’s earned, leave the concrete behind and disappear into open country. “Big City” captures something timeless in the American character: self-reliance, freedom, wide-open spaces and the stubborn conviction that a man ought to be able to live life on his own terms.
