Dr. O’Connor was asked one if there was ever a person who did poorly in all the battery of tests. There are so many different tests that it would seem unlikely that there would be any human being who didn’t do well in one of them. But Dr. O’Connor laughed and said, “Oh, yes, there is a type of person who does badly in all the tests we offer. About one person in 8,000 is absolutely hopeless in all of the tests.” So he was asked, “What do you do about such a person?” Dr. O’Connor said, “Do? We don’t worry about him. He never presents us with a problem. He is usually the president of his firm or is self-employed.”
