The (real) danger of believing that you're the best
The Dunning-Kruger effect is a term coined in 1999 that nowadays is widely used, mostly in the fields of psychology and management, that defines the mental and cognitive state in which people with "low capacity" - a euphemism for the crappy professionals in a company - have an illusory concept of themselves and they erroneously evaluate their ability to do a good job, wrongly believing that they are nailing it and they are regarded like sort of divine entity in their office.
Countless experts who have been studying this phenomenon for years, argue that this feeling of superiority is usually involuntary and that the so-called "low-ability people" do not know how to evaluate the quality of their work objectively, or in this case their incompetence.
On the other hand, according to several studies, people who are to be rockstar level professionals tend to incorrectly assume that tasks that are easy for them are also easy for other people.
Since it was coined in the late twentieth century, the popularity of the concept has been growing year after year in the business sector. In fact, even some clueless companies have been able to detect the reasons why many projects failed.
So if you think you might have been possessed by this ego driven force, make yourself a favor and take a few minutes -or hours- to evaluate how good is your work. Your co-workers will surely appreciate it. If you wonder why so many good ideas have been failing lately, take a look around and perhaps you will spot a few Dunning-Kruger zombies that have been sabotaging a certain project that, on paper, was meant to be a big hit.
