Dunning-Kruger is important concept I have to teach all my science students.

Your typical physics PhD also tends to overestimate their knowledge of biology or medicine because they did well in a class during high school. But in fact, compared to a biology PhD student, the physics student doesn’t know squat.

This is why many people tend to be overconfident in their knowledge about the safely of vaccines because they learned who Louis Pasteur is during HIgh School. But the fact is, if you want to understand the modern medical industry you had better have an MBA. At least you’ll have a basic understanding of how money corrupts medicine.
