Bill D, you are aware that the "McLandress Coefficient" is a fiction, yes? The book, The McLandress Dimension, was written by John Kenneth Galbraith, using a pseudonym. Here's a passage from Galbraith's A Life In Our Times:

"...in 1962, while recovering from hepatitis at my friend Ruth Field's house on Long Island, I invented a 'psychometricist' by the name of Herschel McLandress who had come up with this measure - "the McLandress Dimension." This and his other scientific efforts of the same nature became a book by that title which I published, with a satisfactory response, under the pseudonym of Mark Epernay, the Mark from Mark Twain, Epernay from an old wine crate in the stable where I was working."

Which isn't to say it's not a legitimate way to classify people, by their level or degree of self-absorption, but it would be funny if some one were to get the impression from reading your post that this is a factual rather than a fictional measurement.
