People who think they are smart usually overestimate their abilities.

Personally I don’t buy into the whole measurable intelligence mentality. I am a firm believer that a person without any medically significant cognitive deficiencies are all smart in some way and are experts in some particular field/subject.
Just like nobody is buying the current generation because it’s insane, right?
