"Arthur Jensen Replies to Stephen Jay Gould : THE DEBUNKING OF SCIENTIFIC FOSSILS AND STRAW PERSONS " , http://www.debunker.com/texts/jensen.html , is a good place to start. It's a detailed criticism of Gould's "The Mismeasure of Man" by one of the best psychometricians around. It's got a good bibliography, but is rather dated being from 1982. No matter what you may think of his politics, Steve Sailer also has a lot of good, and more recent, information in his essays on IQ, especially on international comparisons, on his website, www.isteve.com . Richard Lynn's books are supposed to be very good also, but I haven't read them (too many interests, too little time and money).
Right now, my best source for "answers to Arthur Jensen" is Cosma Shalizi. My understanding is that performance on IQ tests is mostly related to culture - even though that was (to some extent) Gould's position.

Shalizi simply doesn't say that.
There are two things you could mean by it. One is that some cultures make you smart. The other is that the IQ test mostly screens for culture and not useful abilities. It is certainly true that culture affects the difference between performance on Raven's matrices and other tests. In particular, the Flynn effect is stronger for Raven's matrices than other tests. Also, sub-saharan Africans do dramatically worse on RM than on other estimates, where they're closer to African-Americans (who do slightly worse on RM than on common tests). In applying this information to the two possibilities about culture, you'd have to decide which testing approach you liked better, which would depend on what you're trying to measure. "g" is not the correct answer to this question.
