Scoring another 98 is Australia, a country with the second-highest human development index in the world. The Australians are also proud of their education system and the literacy rate, estimated to be 99% in 2003.

It might be surprising for some to see Poland so high in the ranking, but if we consider how many prominent scientists, writers, philosophers, artists, and other distinguished personalities this country has given to the world, the result achieved by the Poles in the survey seems just right.


Hungary (average IQ: 99)

One of the smallest countries on the list, Hungary is home to less than 10 million people; what it lacks in size, it greatly makes up for in significant contribution to the world’s arts, music, literature, sports, science, and technology. Hungary is a very smart nation, and the Statistic Brain Research Institute IQ research confirmed that.
