Has he, for instance, singled out any "genes of intelligence", which he or anyone else could analyze, from ancient skeletal samples of Kurgan people, further comparing them with the "genes of intelligence" of, let us say, ancient Minoan or Indus Valley people? Or does his theory entirely rest on the observation that IEs managed to "conquer" many southern countries, with this showing their higher intelligence? Because, if the latter is the case, his would be a perfectly circular argument!

Hart is a bit more complex than that, seeing success in a combination of innate intelligence and opportunity. In a cold climate, people were selected for intelligence but were also kept busy with sheer survival. This way, the great advances were made in moderate/warm zones, not near the equator but not in intelligence-kneading cold zones either. That is why the Germanic adopted writing from the more southerly Romans (or Etruscans), who had it from the Phoenicians, who may have had the idea of phoneic writing from the auxiliary phonetic script used alongside the more formal hieroglyphic script by the even more southerly Egyptians.
Moreover, he insists on random variation as a key factor: before individuals of eccentrically high intelligence can be favoured by selection, they first have to be produced by random variation, which is more likely to happen in a large population, which in turn is more likely to exist in a moderate climate. This is how he explains the higher IQ apparently reported for Chinese than for Eskimoes: the former have by chance produced more, earlier and more exceptional individuals of high intelligence, and these were favoured (extra by China's meritocratic exam system) in the race for maximum procreation. Also, once harsh circumstances have selected for high intelligence, a population is unlikely to lapse back after migration to a pleasant-climate zone, because the intelligent members will continue to outshine the others with novel (including other than survival-oriented) activities and thus attract more and better partners for procreation.
What struck me when reading his book, is that while the rest of us have ignored racist thought as cranky for decades, a few people in that corner of the opinion spectrum have worked hard to get up-to-date and incorporate all the latest in genetics and psychometry into their worldview. It does not follow that they can't be refuted, only that it will now be a serious job to do so. That's the difference with Hindutva crackpots like Kalyanaraman, who don't bother to stay abreast of the progress made by their opponents and instead stay in a self-congratulatory and other-demonizing mood in perpetuity.
