I've spent half a century writing for radio and print (mostly print). I hope to still be tapping the keys as I take my last breath.
The Walking Dumb
There is no shortage in the supply of incompetent people. According to the BBC, “More than one in every 10 workers in England are incompetent at their jobs, a survey of 72,100 employers suggests.” The really frustrating thing for the rest of us is that many of those useless people are unaware they are bunglers.
They are the Russian woman who checked to see how much gas was in her tank at a gas station by using a lighter. Or, the hold-up guy in Long Beach, California, whose gun failed to fire so he peered down the barrel and pulled the trigger.
In 1999, two psychologists at Cornell University, David Dunning and Justin Kruger, studied how people fail to recognize the difference between accuracy and error. They published their results in a paper that aptly describes their findings: Unskilled and Unaware of It: How Difficulties in Recognizing One’s Own Incompetence Lead to Inflated Self-Assessments.
People who are not very smart suffer a dual burden. First, they are dim-witted and second, they lack the cognitive ability to recognize this. In their paper, Dunning and Kruger “ . . . found that participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. Although their test scores put them in the 12th percentile, they estimated themselves to be in the 62nd.”
So, those who actually scored near the bottom self-assessed themselves to be in the smartest third.
Similarly, in a study of the faculty at the University of Nebraska, 90 percent of the teaching staff rated themselves above average, which, of course, is mathematically impossible.
And, who amongst us has not come across a bad driver who is convinced they possess the skills of a Formula One champion?
The Incompetent Bank Robber
Dunning and Kruger began their study because of the actions of a monumentally stupid crook.
McArthur Wheeler robbed two banks in Pittsburgh without wearing a mask. Security camera video of the robberies was played on local telecasts, clearly showing the face of the criminal. Within minutes tips as to his identity reached the police and before the day was done, McArthur Wheeler was in custody.
He couldn’t believe his bad luck and told detectives, “But, I wore the juice.”
It seems Wheeler had found out that lemon juice can be used as invisible ink. So, he reasoned, if he put lemon juice on his face, he would be invisible to security cameras.
He tested the hypothesis by taking a Polaroid of his lemon juice-covered face and, sure enough, his face was invisible. Police were baffled by this but concluded Wheeler was as inept at photography as he was at bank robbing.
New York Magazine reports that when David Dunning read about the hapless bank robber, “He saw in this tale of dim-witted woe something universal. Those most lacking in knowledge and skills are least able to appreciate that lack.”

The Dunning-Kruger Effect is something managers and human resources people have to tussle with constantly.
According to Forbes “ . . . only 39 percent of employees handle constructive criticism by systematically dissecting every step leading up to the thing they just got criticized for.” These are people who are intelligent, recognize they are not perfect and are motivated to correct their deficiencies.
As Dunning and Kruger observe “ . . . most people have no trouble identifying their inability to translate Slovenian proverbs, reconstruct a V-8 engine, or diagnose acute disseminated encephalomyelitis.”
But that leaves 61 percent who don’t deal well with critical feedback. Of course, they are not all suffering from the Dunning-Kruger Effect, but many are.
A Famous Sufferer
Former U.S. President Donald Trump, by the estimation of many, suffers from the Dunning-Kruger Effect. He endlessly brags about his abilities:
- “ . . . my I.Q. is one of the highest―and you all know it! Please don’t feel so stupid or insecure, it’s not your fault.”
- “I’m very highly educated. I know words. I have the best words.”
- “I’m proud of my net worth, I’ve done an amazing job . . . ”
- “I alone can fix it.”
Of course, the world has come to understand that he is challenged by language. Here’s The Guardian “His spelling and grammar are disastrous, he contradicts himself, trails into incoherence . . . ” The Washington Post suggests he speaks at a Grade Six level.
His amazing business acumen has led his companies into bankruptcy four times. He even managed to go broke running a casino.
As for fixing America politically, he racked up an impressive list of failures.
Conservative pundit George Will (Washington Post, May 2017) points out that, “ . . . the problem isn’t that he does not know this or that, or that he does not know that he does not know this or that. Rather, the dangerous thing is that he does not know what it is to know something.”
That’s a clear definition of the Dunning-Kruger Effect.
William Poundstone (Psychology Today, January 2017) reminds us all to have a little humility about our competence: “You may not harbor illusions about your ability to be Commander-in-Chief or devise a brilliant health-care plan. Yet in dozens of quieter ways, we all suffer from an incurable delusion of competence.”
- Not entirely unrelated to the Dunning-Kruger Effect is the Peter Principle. Educator Lawrence Peter put forward this theory in 1969, which states broadly that organizations promote people based on their performance in their current position rather than on whether they have the skills to master their new post. Taken to its logical extreme, the Peter Principle says that eventually, people are raised to a level at which they become incompetent.
- Scott Adams, the Dilbert cartoonist, has proposed the Dilbert Principle. Simply stated, incompetent employees are promoted ahead of competent workers. This shuffles them away from productive work into positions where they can cause the least amount of damage to the organization.

Donald Trump is well aware of his "grade six english" he uses it to help people where english was not their primary language to understand what he is trying to transmit to them
Kari Poulsen from Ohio on September 14, 2017:
LOL, I really enjoyed this. Love John Cleese. But it makes me wonder what I am blind about. :)
Glen Rix from UK on September 14, 2017:
Perhaps, then, if people can't recognise their own stupidity, we are all a little stupid?
Rupert Taylor (author) from Waterloo, Ontario, Canada on September 12, 2017:
Thanks Paula. Glad I was able to bring a little levity into your life, but it remains that the Stupid-in-Chief is in the White House and that affects us all.
Suzie from Carson City on September 12, 2017:
Oh LOL...Rupert, I'm wiping the tears of laughter from my face! The John Cleese video and even funnier, the "stupidity to extreme" video had me howling....
Thanks so much. I really needed this moment of hilarity! I have just had an incredible day, out & about, running errands and also running into so many of these very people! LOL As annoying as this can be and the level of frustration we experience when finding we must deal with yet another Moron, we truly must laugh in the end. There's really not much more we can do to fix "Stupid!!"
If we were grading this article, you get an A+ from me! Paula
