> I’d take “slightly below average but is generally good to work with and tries hard” over “genius asshole” almost any day.

I'd take either before the utterly dangerous "below average hard-working asshole" which tend to quickly rise to managerial positions and cause untold damage with their ineptitude.

"I distinguish four types. There are clever, hardworking, stupid, and lazy officers. Usually two characteristics are combined. Some are clever and hardworking; their place is the General Staff. The next ones are stupid and lazy; they make up 90 percent of every army and are suited to routine duties. Anyone who is both clever and lazy is qualified for the highest leadership duties, because he possesses the mental clarity and strength of nerve necessary for difficult decisions. One must beware of anyone who is both stupid and hardworking; he must not be entrusted with any responsibility because he will always only cause damage."
