Are Native Born, White Americans the Top Dogs?

He wrote a book in 19 23 called a study of american intelligence. He said that, based on the test he had conducted for the army, native born, white Americaans were the intellectual top dogs. And then he said also, the nortic race is a better than what he called the alpine race. The alpine race, in karl's mind, is anyone from eastern europe. It's very like, not wide enough for him. But karl seemed to know what he was talking about. For enough people who seemed to be like minded enough that his ideas just took on like wildfire. Isn't that nice?
