dat u dom bent, daar kunt u niets aan doen, maar dan moet u wel wat vaker uw mond houden.

Ik snap niet dat u zo dom bent dat u uw oordeel laat afhangen van slechts één obscure studie. Het ligt toch voor de hand dat de werkelijkheid gecompliceerder is.
Ons meten van IQ is sterk westers-orthodox geïnspireerd. Natuurlijk dat dit anders werkt op andere culturen. Mijn antwoord op dit stukje van beperkt denken (bron: Amazon):

what is IQ?
At first sight, Lynn and Vanhanen (L+V) appear to have discovered a remarkable and previously unsuspected relationship between IQ and the national wealth of countries. Judging from reviews on this site and others this is clearly an idea which catches the imagination of some readers. However, L+V give a very one sided account. This is a common feature of genetic accounts of intelligence, which leads many to suspect the true motives of such authors. The danger of such a one sided account here is that readers not aware of the full complexities of the issues are seduced into what appears a very straightforward hypothesis - that the poor countires of the world are in their predicament because of the natural intelligence of their population. L and V neglect to point out that the nature of IQ is just about the most controversial topic within modern psychology. There is no agreement between researchers as to what IQ tests measure. Whatever it is they measure, there is no agreement as to how much of this quantity is determined by the environment on the one hand and genetics on the other. L and V adopt the stance that IQ is largely genetic. This is far from accepted, and all the relevant evidence comes from the West. In the rich countries such as the UK and USA, with high standards of educational provision accessible to the majority, performance on IQ tests may well have a substantial genetic component. This is less likely to be the case in the third world, where the majority of the population have little access to good education, not to mention adequate food, housing etc. In other words, IQ in the third world is likely to be an index of access to education. This is further borne out by illiteracy rates. Illiteracy is a consequience of receiving little if any education. Illiteracy rates reported by Unesco correlate -0.73 with L and Vs international IQ estimates. Illiteracy has been shown to cause real brain changes, and reduced abstract problem solving, exactly the kinds of skills measured on the IQ tests reported by L and V. Even these abstract problem solving tests are far from culture free, as Naglieri has shown with his improved tests on which cross racial differences are negligible. In short, L and Vs account is polemical and one sided. It is dangerous in that some readers might be tempted to assume that the text gives an unproblematic account of how third world poverty is a result of low intelligence. Before accepting this simple and unbalanced hypothesis, readers should familiarise themselves with more thorough and balanced accounts, e.g. that of Mackintosh
