I believe these attitudes are somehow commonplace along academia, but I think it extrapolates to several disciplines, including software development or engineering.

There is a misunderstanding between where on the abstraction layer you are standing and how smart you are. The commonplace along mathematicians is that, as we are standing pretty low, we are the smartest of them all, and since there is basically no interaction with people in other layers, this belief gets comfortably reinforced.

Smarts comes in different flavors, and realizing that yours is just one of many and does not work at all in other contexts is hard. Treating others like morons and acting bored is a lousy way to deal with it.
