// explanation
What is the Dunning-Kruger effect?
The Dunning-Kruger effect is when someone who doesn't know much about something thinks they're really good at it [1][2]. It's like when you first learn to ride a bike and think you're amazing, but you don't know all the tricks yet.
Why does it happen?
When you're just starting to learn something, you don't know enough to realize what you're missing [2][4]. You learn a little bit and feel confident, but you don't understand how much more there is to learn.
What does it feel like?
Imagine thinking you're a great cook after making one good meal, even though you've never made fancy sauces or timed multiple dishes together [3]. People with the Dunning-Kruger effect feel certain they're skilled, even when they're not.
How do you fix it?
The more you actually learn about something, the better you get at understanding what you don't know yet [1][5]. As you gain real skill and knowledge, you become more honest about your abilities.
