Eight months later, the Harvard Kennedy School has replicated and expanded on Steve Sailer's PISA analysis ethnicity. The percent of whites who are proficient in math is 41.8 which is better than the scores from France and Iceland and comparable to Australia. New Zealand, and Germany. Reading scores are even better.
They agree with Sailer that Whitey's reading scores are adequate but insist that higher math scores are required since Whitey's percent proficient is "well behind" Germany's (45%) and has as gap of "over 25%" with Finland (57%). Note, in the Finnish comparison they use a simple but effective trick to inflate a difference by ignoring a 15% absolute difference to report a larger relative difference.
They try to make a connection between economic growth and math proficiency and present a graph without Japan. Gee, why wouldn't they want to include Japan?
The data presentation is good but would it be a huge strain on Harvard Kennedy School to calculate a confidence interval or something so we could tell if Ireland is really less proficient than Lichtenstein? Someone may want to know!
