What is the Dunning-Kruger Effect?
Augustan poet and satirist Alexander Pope (May 21, 1688 – May 30, 1744) once said, ‘Fools rush in where angels fear to tread.’ Several years later, English philosopher Bertrand Russell (May 18, 1872 – February 2, 1970) said, ‘The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts.’Does any of these quotes ring a bell?
Life is full of overconfident amateurs and underconfident experts. Indeed, there are moments in life when we believe we’re incredibly good at something we’re terribly bad at, and times when we believe we’re bad at something that we’re exceptionally good at. This phenomenon is psychologically known as The Dunning-Kruger Effect. Simply put, the Dunning-Kruger Effect is a hypothetical cognitive bias which states that people with low competence in intellectual or social domains overestimate their ability. The condition is also known as illusory superiority. The Dunning-Kruger Effect was described by social psychologists David Dunning and Justin Kruger, after which the bias is named. Although certain people are at a higher risk of suffering from the Dunning-Kruger Effect, the condition affects everyone at some point in their lives.Origin of the Dunning-Kruger Effect Hypothesis
Scientists David Dunning and Justin Kruger conducted the original study on the Dunning-Kruger Effect. The 1999 study titled ‘Unskilled and Unaware of It: How Difficulties in Recognizing One’s Own Incompetence Lead to Inflated Self-Assessments’ also became the first documented research work identifying illusory superiority as a form of cognitive bias.
One of Dunning and Kruger’s major reference points was the criminal case of McArthur Wheeler. Wheeler was a middle-aged man who robbed two banks in Pittsburgh on April 19, 1995, with his face covered in lemon. Although this appeared like the dumbest form of disguise by a bank robber, Wheeler actually believed that lemon juice could offer him complete invisibility from the surveillance cameras. The infamous robber’s decision to ‘disguise’ himself in lemon juice was inspired by the fact that lemon juice is used for making invisible ink. According to Wheeler, invisible ink literally translated to an invisible face.
Dunning and Kruger investigated the Dunning-Kruger Effect further in the study ‘Why People Fail to Recognize Their Own Competence.’ In this study, the duo asserts that poor assessment of a person’s competence generally emanates from their ignorance of the standards used in measuring excellence in that particular activity.
For instance, a college graduate having majored in sales and marketing may gloat over their ability to transform a company’s fortunes purely based on their academic qualifications. Such people may be blissfully ignorant of other technical lead generation tips like humor and emotional intelligence.
What Causes The Dunning-Kruger Effect?
The Dunning-Kruger Effect is a neurological condition. According to Dunning, “the knowledge and intelligence that are required to be good at a task are often the same qualities needed to recognize that one is not good at that task—and if one lacks such knowledge and intelligence, one remains ignorant that one is not good at that task.”
Dunning and Kruger further suggest that the phenomenon results from ‘dual burden,’ where not only is a person incompetent. But their incompetence also deprives them of the mental ability to realize just how dumb they are. Therefore, they end up grossly overestimating their abilities. And that’s the biggest irony with this condition, which often makes it difficult to manage.
Besides the inability to recognize one’s lack of skills, the Dunning-Kruger Effect may also result from little knowledge in a subject or topic. Some people may mistakenly believe they possess vast knowledge on a subject when they’ve only scratched the surface of it.
A lack of metacognition is another common cause of the Dunning-Kruger Effect. Most victims of this phenomenon lack the ability to evaluate their skills and potential from outside of themselves. Therefore, they end up forming unrealistic opinions of themselves by analyzing their skills from their already limited and subjective point of view.
Last but not least, the Dunning Kruger Effect may result from the use of mental shortcuts that expedite the decision making process.
It’s also worth noting that while the Dunning-Kruger Effect mainly results from a poor assessment of one’s competence and potential, the phenomenon may sometimes apply to the disabled. Some people living with a disability may have such unrealistic perceptions about themselves that they fail to acknowledge or are completely unaware of the mere fact that they’re disabled.
Numerous subsequent findings have corroborated the hypotheses of Dunning and Kruger in the first studies of the Dunning-Kruger Effect.
One study examined the self-assessment abilities of undergraduate students of introductory courses in psychology. The students were required to assess their intellectual skills in deductive, inductive, and abductive logical reasoning, as well as their sense of humor and English grammar. At the end of the study, the students were asked to estimate their rankings. Competent students underestimated their rankings while incompetent ones overestimated theirs.
Researchers deduced that competent students underestimated their rankings due to the presumption that tasks which were easy for them to perform might have been even easier for other students. On the contrary, incompetent students were totally ignorant of their incompetence.
There are plenty of subsequent studies that have corroborated the original studies on the Dunning-Kruger Effect. Examples include:
• The 2003 study ‘How Chronic Self-Views Influence (and Potentially Mislead) Estimates of Performance’ that identifies inefficiencies in victims of The Dunning-Kruger Effect to process external cues
• The 2004 study ‘Mind-Reading and Metacognition: Narcissism, not Actual Competence, Predicts Self-estimated Ability’ which examines The Dunning-Kruger Effect from the angle of emotional intelligence
• The 2006 study ‘Skilled or Unskilled, but Still Unaware of It: How Perceptions of Difficulty Drive Miscalibration in Relative Comparisons
• The 2008 study ‘Why the Unskilled are Unaware: Further Explorations of (Absent) Self-insight Among the Incompetent’
Who Is At Risk Of The Dunning-Kruger Effect And How Can You Overcome The Phenomenon?
Everyone is susceptible to the Dunning-Kruger Effect.
However, the phenomenon tends to be common among college students. Many students have a tendency to overestimate their academic potential, only to be proven wrong when examination results come out.
The Dunning-Kruger Effect is also common among coworkers. In one study involving high-tech firms, researchers discovered that 32 – 42% of software engineers overestimated their skills. Most of the respondents believed that they were in the top 5% of their companies.
The Dunning-Kruger Effect may also result from unrealistic expectations about the future. One survey found that 21% of Americans believed they were likely to become millionaires within the next ten years.
The Dunning-Kruger Effect has also been observed in social domains, especially with regard to emotional intelligence. People with this phenomenon are usually inefficient at discerning the feelings of others and responding appropriately.
Without proper managing, The Dunning-Kruger Effect may adversely affect your productivity and social relationships. A businessman who grossly overestimates his abilities may believe that he’s serving his clients’ needs effectively. This misconception could affect how he manages client feedback and constructive criticism.
Fortunately, there are numerous ways to overcome The Dunning-Kruger Effect.
The first tip for solving The Dunning-Kruger Effect is understanding that no one is immune from the phenomenon. It’s also important to note that the condition affects the incompetent and the competent alike.
You can then implement any of the following strategies to overcome Dunning-Kruger Effect:
• Accept your limitations
• Continue honing your skills in an area of study, including your areas of expertise
• Inquire from other people on their secrets for excellence
• Approach every problem pragmatically
Conclusion
The Dunning-Kruger Effect is a cognitive bias that affects everyone at some point in their lives. While the condition is not exactly medical, it can adversely interfere with your workplace productivity and social interactions. Thankfully, there are numerous tips you can implement to manage or prevent this phenomenon from taking a toll on your life.
