There are lots of factors that can influence defining and measuring intelligence. First of all, some people can get anxious and nervous once they are aware that somebody is testing them, what, in addition, can result in low score on such tests. That don’t make them stupid, but the test can show so. Another point is that the test results can depend on one’s mood, as well. If you had an awful day, and you are entirely out of focus, the test may show bad results. Therefore, IQ tests shouldn’t be taken as the only parameters of somebody’s intelligence. And we asked what about the countries’ intelligence?
Lynn and Vanhanen conducted a research of 80 countries’ IQ from 2002 up to 2006. The results are amazing! What is more, PISA made another research about top performers in mathematics, science and reading for all countries. What Insider Monkey did is by comparing those two researches they got 30 Smartest Countries With the Highest Average IQ in the World in 2017. Check it out!
