These Are the Countries With the Highest IQs

6. Japan average IQ - 104.2

Japanese students spend more time at school than many other countries - and it shows! They are one of the most successful when it comes to attending tertiary schools as well as achieving high scores on international tests like PISA for math and reading literacy.

It's also worth mentioning that Japanese children have some of the best access to cognitive stimulation due to their low ratio of screen time compared to Westerners. In Japan, kids typically only get a certain number of hours per week which is fairly standard among Asian countries because they understand how important it is not to use technology too much - especially before a child reaches adolescence.
