Brains are delicate things…
From the Yes Minister episode “The Right to Know”
Sir Humphrey: There are four words you have to work into a proposal if you want a Minister to accept it.
Sir Frank: Quick, simple, popular, cheap. And equally there are four words to be included in a proposal if you want it thrown out.
Sir Humphrey: Complicated, lengthy, expensive, controversial. And if you want to be really sure that the Minister doesn’t accept it you must say the decision is courageous.
Bernard: And that’s worse than controversial?
Sir Humphrey: (laughs) Controversial only means this will lose you votes, courageous means this will lose you the election.
