The blogger says that the average IQ in Europe and North America is 100 but that "the mean IQ of the world is a tad less than 90 today, and it's expected to fall to about 86 by 2050." So the blogger thinks that some races are much stupider than Europeans, and that if their share of the global population rises, average intelligence will fall. That sure sounds like he thinks this is a genetic difference and not poverty, disease, or lack of education.

The blogger cites a website which cites Richard Lynn for these 'facts'. So this is about race and IQ, quod erat demonstratum.
