Have you ever noticed how sometimes beginners can be confidently wrong about things they barely understand? But industry-savvy with years of experience seem to be too humble?
This is the Dunning–Kruger effect, a classic psychological theory. First proposed in 1999, the theory describes how we perceive our own competence. It is not a judgment itself, but it often hints at a sarcastic sense of humor: beginners with low skills frequently overestimate their ability, while those with expertise may underestimate themselves.
Essentially, it is a cognitive bias: the less you know, the less likely you are to know you don’t know. This is strictly speaking, not about “intelligence”, but a glitch in metacognition, which is the ability to step back and accurately monitor our own performance.
This occurs because the very skills required to be “good” at a task are the same skills needed to recognize that you are “bad” at it. Without a baseline of knowledge, the brain fills in the gaps with felt confidence. That said, wisdom is not the absence of mistakes, but the developed capacity to see our own limitations. When we lower our defenses and move out of a “certainty” mindset, we create the safety necessary for true learning.
Also, ironically, confidence doesn’t always match competence; it is more likely to match merely self-perception.
