Re: HBD -- Farming and Inheritance
If, for example, the people of Charles Murray's hypothetical Belmont and Fishtown start off with the same average IQ, but Belmont experiences an economic boom, the smart people from Fishtown will come over, raising the average IQ of Belmont and lowering that of Fishtown (which, ironically, is what is actually responsible for what Murray describes in his book). This is the process that SMAZ is claiming is responsible for the differences between Northern and Southern Italy (and presumably the Northern and Southern U.S.).
Of course, this process does not require a priori that the two regions need start with the same average IQ, and there is the issue of why one became economically productive while the other didn't. As well, we are left wondering why one began to prosper while the other didn't. It could be circumstances (say, oil, or a favorable shipping location), but it could just as easily be the initial differences in the population. In other words, proving the existence of brain drain doesn't disprove that there were initial differences in the average IQ.
