There is a graph, which differentiates countries with lower and higher IQ grades by shading. For example, dark violet shade reflects countries with greater IQ levels. Areas with medium IQ grades around the world are significant.
Nations are subdivided based on the IQ grades, and different ranks are allotted to each. The minimum country IQ score on earth is 59, and the maximum is The difference between them and the countries with the highest IQ level is 49 points. These countries are Singapore and Hong Kong, with a grade of Tests to measure IQ are conducted across the globe. And further, their results are gathered to decide intelligence. This is based only on IQ levels. If you wrongfully assume that intelligence is a matter of genetics only, differences between races could be used to justify racism.
After all, Asians on average score somewhat higher than whites in a traditional IQ test. And whites in turn score a bit higher than blacks. Do note, this very likely reflects average educational level and other factors and not race. It is very unlikely that intelligence as it is measured is hereditary only. There are numerous other factors which could explain the differences found.
Factors like culturally determined attitude towards work, socioeconomic status, health and educational differences are divided unequally between races. In fact it would be illogical if no differences would be found between races.
Scottish scientists have found taller people to score higher than shorter people, on average. According to 'popular belief' some nations are not as smart as others.
There are many differences in IQ scores between countries. The primary cause is the educational level. The 'higher educated' a country is, the 'smarter' the country is.
Although a lower IQ score does not in itself prevent social success, successful people do more often have a higher IQ. Determining which countries are the smartest in the world is difficult because there are so many different factors that can be considered.
Obviously, there exist challenges to any attempt to land on a single clear-and-simple answer. Nonetheless, population and intelligence experts continue to devise new methods and approaches that bring them closer and closer to a realistic ranking of the world's smartest countries. Some of the best-known and more widely publicized studies of world intelligence are conducted by British psychologist Richard Lynn. In a study titled The Intelligence of Nations , Lynn and collaborator David Becker measured the average IQ of citizens across nations and calculated estimated scores for another The top of the list looks as follows scroll to the table at the bottom of the page for the rest.
Some detractors take issue with the methods Lynn uses to compute estimates when hard data is unavailable. Others accuse Lynn, an outspoken eugenicist , of using his data to support scientifically inaccurate theories that promote white supremacist beliefs.
