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.
