Car Guy asks:
Would it be fair to compare the US education system with that of countries such as Japan, South Korea and Germany?
People are always comparing US test scores with those of all Asian countries in East Asia and nearly all White countries in Europe. When the US falls behind say Finland, Taiwan or Singapore, rightwingers screech that the US public school system is failing and therefore we need to dismantle it in various ways such as charter schools, vouchers, defunding, etc.
These comparisons are all false due to differential IQ’s between ethnic groups in the US and those of other nations.
Japan and South Korea = pure East Asian. Higher IQ (105) than white majority US (98).
Germany = all White. German IQ is ~103; US IQ is 98. The US is only 66% White, and the rest is largely Black and Hispanic with much lower IQ’s than Whites. Totally unfair comparisons with all of them.
IQ US Ethnic group Whites 103 Hispanics 90 Blacks 87.2*
*Black estimate is my estimate. Others would put it lower at around 85. The White and Hispanic estimates seem to be pretty much valid. There may be some upward movement on the order of 1-2 points in both Black and Hispanic IQ’s in the last few decades for unknown reasons.
As you can see, Blacks and Browns score much lower on IQ’s than Whites, pulling the whole US average down, which will be reflected on test scores. Due to differential IQ’s US students will tend to score poorer than those of all White European nations and all-Asian Asian nations.
