Writing at Taki’s Magazine, Steve Sailer looks at achievement levels of Asian, white, Hispanic, and black students in colleges and in the public schools. Apparently not afraid of accusations of racism, he wades right in and describes what is known about achievement gaps, which are substantial.
He debunks some current theories which ascribe all differences to discrimination or “segregation.” What he doesn’t do is say what the actual causes of such gaps might be, hoping to avoid I suppose an accusation of blaming the victim.
Reading between Sailer’s lines, and perhaps putting words into his mouth, I’d infer he believes the difference is the extent to which parents in each group lean hard on their kids to achieve academically. That, in turn, is influenced by subgroup cultural differences. Hat tip to Lucianne.com for the link.
