Déformation professionnelle
From wikipedia, Déformation professionnelle:
a tendency to look at things from the point of view of one's own profession and forget a broader perspective. It is a pun on the expression "formation professionnelle," meaning "professional training." The implication is that all (or most) professional training results to some extent in a distortion of the way the professional views the world.
It's too common. It's frustrating. Rant over.
