I was reading a book on a totally unrelated topic, and in that book they related the way that Prussian General Staff used to rate upcoming young officers.
Type 1 - Smart and energetic
Type 2 - Smart and lazy
Type 3 - Stupid and energetic
Type 4 - Stupid and lazy
Type 1 officers were groomed for the General Staff someday. Type 2 officers would be routed into mid-level commands where they could be trusted to be competent and would not upset the established order. Type 4 officers would be frozen at the lower ranks until they were let go for some inexcusable action or evenually left on their own. Type 3 officers were the problem - they didn't know what they were doing but went ahead and did it anyway.
T is a Type 3 --
