I had never before heard of La Griffe du Lion. His article was so full of egregiously bad methodology and other mistakes that I at first assumed it was a satire of racist pseudoscience, the sort of thing that might be written for the
Annals of Improbable Research or (if you're Alan Sokal) Social Text.
To mention just one example, the article's thesis is that a nation's "smart fraction" of the population predicts per capita GDP better than average IQ, but then uses (highly questionable) "data" on average IQ to pretend to estimate the smart fraction by assuming a Gaussian distribution. As any competent scientist would notice, however, the assumption of Gaussian distributions can't be used to estimate the "smart fraction" without the further assumption of a specific variance or standard distribution, for which there are no data available. In short, the article claims that data on average IQ are inadequate to predict per capita GDP, but then pretends to obtain a better prediction of per capita GDP from precisely that inadequate data by making a sequence of unsupported assumptions. We're used to seeing that kind of argument in rmcg, but scientists recognize it as a form of scientific fraud known as drylabbing.
