The Controversy of National IQ Estimates
The podcast delves into Richard Lin's national IQ estimates, which sparked significant controversy due to their implications about intelligence across different countries. These estimates show a wide range, with countries like Malawi scoring as low as 60 and nations such as Singapore reaching up to 108. Critics argue that Lin's methodology relies on questionable data sources, asserting that high-quality IQ testing is rarely conducted on entire populations, particularly in sub-Saharan Africa.
