One of the painful things about our time is that those who feel certainty are stupid, and those with any imagination and understanding are filled with doubt and indecision.
Actually I am Talking About The Dunning-Kruger Effect
The Dunning-Kruger effect (also known as Mount Stupid or Smug Snake), named after David Dunning and Justin Kruger of Cornell University, occurs where people fail to adequately assess their level of competence or specifically, their incompetence at a task and thus consider themselves much more competent than everyone else.
This lack of awareness is attributed to their lower level of competence robbing them of the ability to critically analyse their performance, leading to a significant overestimation of themselves. In simple words it’s “people who are too ignorant to know how ignorant they are”The inverse also applies: the unusually competent people tend to underestimate their ability compared to others; this is known as impostor syndrome.
The principle is illustrated indirectly by the common saying that “I’ve learned enough about to know what I don’t know.” The implication is that someone who hasn’t learned much about the subject would have no appreciation for how much there is to learn about it, and so might grossly overestimate their level of understanding.
The effect can also be summarized by the phrase “a little knowledge is a dangerous thing.” A small amount of knowledge can mislead a person into thinking that they’re an expert because this small amount of knowledge isn’t a well known fact.
The fool doth think he is wise, but the wise man knows himself to be a fool.
Dunning and Kruger properly proved its existence in their seminal, 2000 Ig Nobel Prize winning paper “Unskilled and Unaware of It” doubtless at great risk to personal sanity
