If you don't like that link - which is just one of the many I got when searching for 'national IQ average' there are many other similar studies to be had. Here's a few of them, again just some results from the first page in my SearXNG instance. The results are not identical but they are comparable. https://international-iq-test.com/en/test/IQ_by_country https://international-iq-test.com/en/test/IQ_by_country https://www.worlddata.info/iq-by-country.php https://www.worlddata.info/iq-by-country.php https://www.universaliqtest.com/statistics/average-iq-by-country https://www.universaliqtest.com/statistics/average-iq-by-cou... https://www.datapandas.org/ranking/average-iq-by-country https://www.datapandas.org/ranking/average-iq-by-country https://www.researchgate.net/publication/229401257_National_IQs_calculated_and_validated_for_108_nations https://www.researchgate.net/publication/229401257_National_... https://openpsych.net/files/papers/Parra_2025a.pdf https://openpsych.net/files/papers/Parra_2025a.pdf

> Countries with fewer than 100 test-takers were excluded from the ranking due to limited sample size and are shown in gray on the map above. How generous of them.

You've just provided: (1) Several surveys backed by anonymous online "IQ test" web sites. (2) Richard Lynn, whose numbers are essentially fraudulent. (3) Emil Kirkegaard, the famous Danish white supremacist. The counterargument is very simple: countries don't generally do IQ surveys. Most people on HN have never been asked to take a calibrated IQ test. The data simply doesn't exist.

  Don’t worry, they got data from a whole 5000 people in Australia and 300 people in Afghanistan! I’m sure that’s generalizable to the whole country’s worth of 28 and 40 million, respectively.

    Hard to beat Richard Lynn's sample of Senegal, which came from 57 children in a malaria hospital.
