Dunning-Kruger Effect

Did you know about the Dunning–Kruger effect? It is a cognitive bias where people with low ability, expertise, or experience tend to overestimate their ability or knowledge.

We often face this psychological paradox in life: less competent people see themselves as professionals and qualified, while more competent people tend to doubt themselves and their abilities.
The lower the skill level, the higher the self-confidence.

This brings us back to this famous statement from Charles Darwin:
“Ignorance more frequently begets confidence than does knowledge”
