Background: The pseudoscientific nature of the “IQ maps of the world” prepared by Richard Lynn becomes more obvious if Lynn’s substandard methodology and his misrepresentation of scientific work of other authors is reviewed, including in some of his older pseudoscientific studies. Method: The present study focuses on Lynn’s methods in his 1993 article, in which Lynn used external head measurements from outdated sources to support his dogma of intellectual inferiority of women compared to men and of blacks compared to whites. Results: Noteworthy in Lynn's 1993 article are his misinterpretation of very low correlations of head size measures to IQs, his blatantly selective reporting only of confirmatory data, and his factual misrepresentations of statistical conclusions reported by other authors. Similar methodological concerns about Lynn's other racial studies were also raised by Leon Kamin and by various other scientists. Conclusions: Lynn’s 1993 article is replete with methodological errors and misrepresentations of data and of statistical conclusions presented by other authors.
