I don't doubt it, but I had to wonder where they got the hard data. They didn't. This note was on the site:

*It bears mentioning that Lynn's studies, while comprehensive, tend to spark considerable debate. Some researchers dispute the techniques Lynn employs to calculate estimates when hard data is lacking. Others claim Lynn, an unabashed eugenicist, misinterprets his data to support conclusions that are both scientifically inaccurate and supportive of white supremacy.

Just wondering where they came up with everyone's IQ score to figure the average per country. Regardless, the U.S. is getting dumber.

High school counselors don't even give lip service to trades. On counseling nights for parents the presenters gush over the UC system (the most expensive option), talk a bit about the state college system and as a aside mention junior colleges. Trades, forget it. Not worthy of mention, coupled with the fact that most shop programs have been gutted. All this serves to make students interested in a trade as a profession underserved second class citizens. Everyone is aimed at a college degree despite the fact that only four in ten Americans ever earn a bachelor's degree. Our educational system is not serving the nation.
