I wonder what might ever be the cause?

It’s a source of mixed amusement and despair to see the media simultaneously celebrate a) a declining white population of American while lamenting b) declining average SAT scores.

Scores on the SAT have sunk to the lowest level since the college admission test was overhauled in 2005, adding to worries about student performance in the nation’s high schools.

The average score for the Class of 2015 was 1490 out of a maximum 2400, the College Board reported Thursday. That was down 7 points from the previous class’s mark and was the lowest composite score of the past decade. There were declines of at least 2 points on all three sections of the test — critical reading, math and writing.

The steady decline in SAT scores and generally stagnant results from high schools on federal tests and other measures reflect a troubling shortcoming of education-reform efforts. The test results show that gains in reading and math in elementary grades haven’t led to broad improvement in high schools, experts say. That means several hundred thousand teenagers, especially those who grew up poor, are leaving school every year unready for college.

One can only conclude that the journalists writing articles like these didn’t do very well on the SAT themselves. It’s not as if it’s any great mystery what happens when lower IQ populations are permitted to invade a higher IQ population; both England and Denmark have observed statistically significant decreases in average IQ since their immigrant populations began to grow.

Diversity is intrinsically opposed to Progress of any sort that involves a) technology, b) wealth, or c) quality of life.
