When You Don't Know What You Don't Know Or

The ‘Ignorance Of Ignorance’ Or The ‘Liberal Conundrum.’

Or as Psychologists label it:

We all know people like this.

The realm of the “unknown unknowns.”
In 1999, psychology researchers David Dunning and Justin Kruger published a study titled “Unskilled and Unaware of It: How Difficulties in Recognizing One’s Own Incompetence Lead to Inflated Self-Assessments” in which they described our tendency to to hold overly favorable views of our abilities.
The researchers presented the participants with four tests assessing humor, logical reasoning, and grammar. Then, they asked participants to evaluate their own performance, how well or poorly they thought they did on the tests.
Not only did most participants overestimate their performance, but the least competent participants, the ones that scored in the bottom quarter, were more likely to overestimate their performance. The least they knew, the more they thought they knew.
