You clearly didn't even read these wikipedia pages. Although they are about two different publications (one from 2002 and the other from 2006), each book is basically the exact same, and the latter presents the exact same flimsy evidence as the former.

Also, from the contents of these very same wikipedia articles: https://en.wikipedia.org/wiki/IQ_and_the_Wealth_of_Nations#R... https://en.wikipedia.org/wiki/IQ_and_Global_Inequality#Recep...

> Several negative reviews of the book have been published in the scholarly literature. Susan Barnett and Wendy Williams wrote that "we see an edifice built on layer upon layer of arbitrary assumptions and selective data manipulation. The data on which the entire book is based are of questionable validity and are used in ways that cannot be justified." They also wrote that cross country comparisons are "virtually meaningless."[4]

> Richardson (2004) argued, citing the Flynn effect as the best evidence, that Lynn has the causal connection backwards and suggested that "the average IQ of a population is simply an index of the size of its middle class, both of which are results of industrial development". The review concludes that "This is not so much science, then, as a social crusade."[3]

> In a book review for the Journal of Economic Literature, Thomas Nechyba wrote that "such sweeping conclusions based on relatively weak statistical evidence and dubious presumptions seem misguided at best and quite dangerous if taken seriously. It is therefore difficult to find much to recommend in this book."[6]

> The methods of the study were criticized by Richard E. Nisbett for relying on small and haphazard samples and for ignoring data that did not support the conclusions.[10]

> University of Reading geographer Stephen Morse also criticized the book (as well as IQ and the Wealth of Nations), arguing that the authors' hypothesis rests on "serious flaws". Morse also argued: "The central dilemma of the Lynn and Vanhanen case rests with their assumption that national IQ data are primarily (not wholly) a function of innate ability, which in turn is at least partly generated by genes. There are many assumptions of cause–effect in here, and some of them involve substantial leaps of faith."[11]

> Evolutionary biologist Satoshi Kanazawa claimed in 2008 to have found support for Lynn's theories.[10] Kanazawa's study has been criticized for using the Pythagorean theorem to estimate geographic distance, despite the fact that this theorem only applies to flat surfaces and the Earth's surface is roughly spherical. Other problems identified in this study include that Kanazawa incorrectly assumed that individuals migrated from Africa to other continents migrated as the crow flies, and ignored that geographic distance and evolutionary novelty do not always correspond to each other.[11]

> Earl Hunt cited Lynn and Vanhanen's work as an example of scientists going far beyond the empirical support to make controversial policy recommendations, and as such as examples of irresponsible uses of science. Hunt argues that in their argumentation they both made the basic mistake of assigning causality to a correlation without evidence, and that they made "staggeringly low" estimates of Sub-Saharan African IQs based on highly problematic data. He considers that by their negligence of observing good scientific practice Lynn and Vanhanen are not living up to the basic responsibility of scientists to make sure that their results can function as reasonable empirical support for policy decisions.[19]

> There's a lot of emotional hysterical screeching accusations of "racism" but those aren't valid arguments.

This is simply not true. I'm arguing that your claim is not based on solid rational foundations. You are the one throwing around irrational accusations, not me.
