I know that stupidity is more common than "common" sense, which is really deductive reasoning ability.
Someone, I think von Runstedt, gave a summary of the qualities of military officers and which jobs they were suited for. For instance, a brilliant mind with adequate patriotism and planning skills made a good general. An active man with intelligence could lead attacks well; a lazy one with average intelligence might make a good supply officer. Stuff like that...
But he said the man you had to beware of is the one who is both stupid and aggressive.
