Dunning–Kruger-Effect

• A bias in which incompetent persons suffer from illusory superiority, untruly assessing their ability as much higher than it really is. 
• This is due to their inability to recognise their inaptitude to evaluate themselves accurately.

E.G.: A person who has never stood on a surfboard before is confident that he can glide through the waves as elegantly as professional surfers. Someone who has had their first experience on a board in the surf is no longer as confident. And the surf crack with many years of experience can confidently assess his skills correctly.

What can you do about it?

• Try to recognize your own mistakes and shortcomings.
• Ask for feedback from trusted people.
• Be curious, open and committed to learning more about this effect in order to recognise it and combat the tendency to think of yourself as an expert.
