In discussing why in LOTR Saruman's battle campaign is terrible:

"Saruman is an builder, engineer, plotter and tinkerer. Given his personality, he strikes me as exactly the sort of very intelligent person whose assumes that their mastery of one field (effectively science-and-engineering, along with magic-and-persuasion, in this case) makes them equally able to perform in other, completely unrelated fields (a mistake common to very many very smart people, but – it seems to me, though this may be only because I work in the humanities – peculiarly common to those moving from the STEM fields to more humanistic ones, as Saruman is here). I immediately feel I understand Saruman sense of “I am very smart and these idiots in Rohan can command armies, so how hard can it be?” And so I love that this overconfidence leads him to man-handle his army into a series of quite frankly rookie mistakes. After all, the core of his character arc is that Saruman was never so wise or clever as he thought himself to be."
