Sorry

why is a person from a council flat less intelligent

Someone landed here after asking the above question. I haven't got the answer. Do you? Intriguing premise lies behind it and one I'd never considered which is, of course, not the only reason why I don't have the answer. I'm also not quite sure why I felt I needed to start with an apology for answering this rather distasteful little question. The search came from a Glasgow academic source. Which actually doesn't make the whole thing feel better, though perhaps that does give the entire situation a bleakly comic overtone.
