What do stupid people talk about

The researchers also found that as a result of this belief, these women were more likely to refuse to enter a science competition. Dunning and his colleagues have also performed experiments in which they ask respondents if they are familiar with a variety of terms related to subjects including politics, biology, physics, and geography. Along with genuine subject-relevant concepts, they interjected completely made-up terms. In one such study, approximately 90 percent of respondents claimed that they had at least some knowledge of the made-up terms.

Consistent with other findings related to the Dunning-Kruger effect, the more familiar participants claimed that they were with a topic, the more likely they were to also claim they were familiar with the meaningless terms. As Dunning has suggested, the very trouble with ignorance is that it can feel just like expertise. So what explains this psychological effect? Are some people simply too dense, to be blunt, to know how dim-witted they are? Dunning and Kruger suggest that this phenomenon stems from what they refer to as a "dual burden.

Incompetent people tend to:. Dunning has pointed out that the very knowledge and skills necessary to be good at a task are the exact same qualities that a person needs to recognize that they are not good at that task.

So if a person lacks those abilities, they remain not only bad at that task but ignorant to their own inability. Dunning suggests that deficits in skill and expertise create a two-pronged problem. First, these deficits cause people to perform poorly in the domain in which they are incompetent. Secondly, their erroneous and deficient knowledge makes them unable to recognize their mistakes.

The Dunning-Kruger effect is also related to difficulties with metacognition, or the ability to step back and look at one's own behavior and abilities from outside of oneself. People are often only able to evaluate themselves from their own limited and highly subjective point of view.

From this limited perspective, they seem highly skilled, knowledgeable, and superior to others. Because of this, people sometimes struggle to have a more realistic view of their own abilities. Another contributing factor is that sometimes a tiny bit of knowledge on a subject can lead people to mistakenly believe that they know all there is to know about it. As the old saying goes, a little bit of knowledge can be a dangerous thing.

A person might have the slimmest bit of awareness about a subject, yet thanks to the Dunning-Kruger effect, believe that he or she is an expert.

Other factors that can contribute to the effect include our use of heuristics , or mental shortcuts that allow us to make decisions quickly, and our tendency to seek out patterns even where none exist. Our minds are primed to try to make sense of the disparate array of information we deal with on a daily basis.

As we try to cut through the confusion and interpret our own abilities and performance within our individual worlds, it is perhaps not surprising that we sometimes fail so completely to accurately judge how well we do.

So who is affected by the Dunning-Kruger effect? Unfortunately, we all are. This is because no matter how informed or experienced we are, everyone has areas in which they are uninformed and incompetent. You might be smart and skilled in many areas, but no one is an expert at everything. The reality is that everyone is susceptible to this phenomenon, and in fact, most of us probably experience it with surprising regularity.

People who are genuine experts in one area may mistakenly believe that their intelligence and knowledge carry over into other areas in which they are less familiar. I would set exams to test students on knowledge I knew they would forget as soon as they walked out of the examination room.

I spent large chunks of my days sitting in meetings which everyone present knew were entirely pointless. My personal life was worse. Clearly I had a personal interest in trying to work out why I, and millions of others like me, could be so stupid so much of the time. After looking back at my own experiences and reading the rapidly growing body of work on why humans fail to think , my co-author and I started to come to some conclusions.

Having a high IQ score does not mean that someone is intelligent. IQ tests only capture analytical intelligence; this is the ability to notice patterns and solve analytical problems. Most standard IQ tests miss out two other aspects of human intelligence: creative and practical intelligence.

Creative intelligence is our ability to deal with novel situations. Practical intelligence is our ability to get things done. For the first 20 years of life, people are rewarded for their analytical intelligence. Given an anchor of a thousand feet, their estimates increased seven-fold. Rather, they wanted to understand how these biases correlated with human intelligence. As a result, they interspersed their tests of bias with various cognitive measurements, including the S.

The results were quite disturbing. What explains this result? One provocative hypothesis is that the bias blind spot arises because of a mismatch between how we evaluate others and how we evaluate ourselves. When considering the irrational choices of a stranger, for instance, we are forced to rely on behavioral information; we see their biases from the outside, which allows us to glimpse their systematic thinking errors. However, when assessing our own bad choices, we tend to engage in elaborate introspection.

We scrutinize our motivations and search for relevant reasons; we lament our mistakes to therapists and ruminate on the beliefs that led us astray. Did you know your brain is actually hard wired to look on the bright side of life? Could we all do with a bit more silence in our lives? Contrary to popular belief, there is little evidence that a midlife crisis actually exists.
