Elizabeth Chin has written an excellent scholarly takedown, in the form of a “letter from your thesis reader,” of Jason Richwine’s 2009 Harvard PhD dissertation, ” IQ and Immigration.”
I’ve not read Richwine’s thesis, though I probably will at some point. And you probably haven’t either. But, you’ll still find Chin’s post informative and compelling.
While you are on the subject have a look at this: Harvard Students Demand Investigation Into Jason Richwine’s Thesis On Hispanic IQ
