The title reads to me as a tautology - we use "clever" as opposed to "intelligent" or "formidable" to connote self-contained, puzzle-like displays of intellect. If you are clever but also pragmatic and effective, people will start using very different words to describe you.
I think clever is also used differently among Brits than Yanks. Brits equate it with intellect and imagination. Americans see cleverness less charitably, as an self-serving tactic in a game that leads to winning. A clever person in the States is often just a trickster.
