It clears up a lot of mystery about what has been happening to human beings over the past twenty years. I have said on this blog many, many times I did not understand how human genetic quality could plunge with that kind of rapidity in a mere fifty years. The numbers don't add up. Even if morons were having four children for every one by somebody who can walk and chew gum at the same time, there's no way to explain how average American IQ could plummet from 104 in 1955 to 97 in 2009. That's not possible and another factor had to be at work in there somewhere.
