I'm thinking along the lines of existential awareness of humans, and the occasional tendency of some people when they become skilled in a field to somewhat lose it. Two examples I've frequently encountered:

Doctors - on medical matters, their opinion on a subject trumps the opinions of all non-formally-educated people

Developers - developers who are admittedly "smarter" than others thinking their argument is always correct

Is there a term for the phenomenon of someone losing the (formerly present) ability to conceive of their own fallibility? Hubris would be a good example, but I'm wondering if there's a more scientific description for this phenomenon.
