And do you know what this is called? The Dunning-Kruger effect. The concept behind the same has been a well-established rule for centuries. This effect is described by Wikipedia as a cognitive bias in which unskilled individuals suffer from illusory superiority, mistakenly rating their ability much higher than is accurate’.
The bias is said to be as a result of the metacognitive inability of the unskilled to acknowledge their own ineptitude. The Dunning-Kruger effect was first tested by two gentlemen from Cornell University going by the names David Dunning and Justin Kruger in 1999.
The carried out a study in which participants were tested on their grammatical skills, logical reasoning skills, as well as humor, followed by which the participants tested their own abilities in those subjects. Those who ranked in the bottom quartile were seen to be overestimating their own abilities. The lot falling in the twelfth percentile had estimated themselves to be in the sixty-second percentile.
Generally speaking, Dunning and Kruger established that incompetent individuals overly estimate their own skill level and fail to recognize their own inadequacies and the same people also don’t recognize the skill of other individuals. But here’s their eye-opener: when they do get around to train to improve their skills, they tend to become increasingly aware of their own inabilities. You should also look up the Peter Principle.
