The Dunning-Kruger effect is a cognitive bias where people who are unskilled or lack knowledge in a particular area overestimate their ability and competence. It’s named after the two psychologists, David Dunning and Justin Kruger, who first described the effect in a 1999 study.
The reason for this effect is that people who are unskilled or lack knowledge in a particular area, don’t have the ability to accurately evaluate their own abilities. They don’t have enough knowledge or experience to recognize their own incompetence. As a result, they tend to overestimate their own abilities and think they are better than they actually are.
It’s important to note that this effect is not limited to a specific area or domain, but it can happen in any area of life, whether it’s in academics, sports, or in the workplace.
One real-world example is how many people think they are better drivers than they actually are. Studies have shown that the majority of drivers rate themselves as above average, even though it’s statistically impossible for more than half of drivers to be above average.
The Dunning-Kruger effect can have real-world consequences, as people who overestimate their abilities may make poor decisions or take unnecessary risks. It’s important to be aware of this bias and try to be objective when evaluating our own abilities. It’s also good to seek feedback from others who have more knowledge and experience in a particular area. It’s a good reminder to stay humble and not to overestimate our own abilities.
