Average IQ in Europe by country (map) by Jakub Marian Tip: Did you know that “iron” is pronounced as “I earn”, not as “I Ron”? Learn more about the most common pronunciation mistakes in English (PDF version ) Note: This article is part of my extensive collection of statistical maps . Please note: Quality of education greatly influences IQ scores, i.e. a lower average IQ is more indica tive of lower access to widescale quality education rather than innate intelligence (see my explana tion of the issue). Also, testing conditions influence results; wealthier countries are more likely to be able to afford better testing conditions for participants. The data may be outdated for some countries (not all uptodate statistical data was available for all countries). Because of inevitable statistical errors, isolated figures must be taken with a grain of salt. Before using strong words in the comments, please consider: My intention with the map wasn’t to advertize or ridicule any particular country (I didn’t know the numbers beforehand). I just created a visualization of statistical data based on a highlycited scientific paper, just like I have done for dozens of other maps. Lower access to quality education anywhere in the world is in no one’s interest (maybe apart from politicians and companies wanting to conrol people). The correct question we should ask therefore is: What is the reason behind the trends we see? What can we, the European society, do to help countries with worse performing education systems?
