The Dunning-Kruger effect may be the most popular bias on the internet because it gives us the perfect reason to laugh at other people.
Wikipedia tells us what you and me have always suspected: “people of low ability suffer from illusory superiority, mistakenly assessing their cognitive ability as greater than it is.”
Bad designers suffer from it: they treat design like art. But design is not art, it is problem solving. As a UX designer you have four responsibilities:
- Understand the user
- Try to fix the users problem
- Test whether your assumptions were correct
- Try to do it better
Stick to these principles and you’ll never suffer from the Dunning-Kruger effect.
