Introduction

Intelligence quotient (IQ) has always been a subject of intense debate and numerous studies. Amidst the controversy, it's crucial to remember that national IQ averages are both useful and somewhat contentious illustrations.

  • The Asian countries, especially East Asia, lead by a wide margin in terms of average IQ scores. With Singapore, Hong Kong, Taiwan, Japan, and China in the top 6, the emphasis on education in these countries and their cultural focus on intellectual achievement can be seen as a significant contributing factor.
  • On the lower end of the spectrum, nations such as Nepal, Sierra Leone, Liberia, and Guatemala exhibit significantly lower IQ averages, sitting below an IQ score of 50.
  • More affluent nations typically appear to have higher average IQ scores. For example, the United States, United Kingdom, Australia, Germany, and the Netherlands all rank within the top quarter of the list.
  • There seems to be a regional pattern among less economically developed countries having lower average scores. African nations like Sierra Leone, Liberia, Cape Verde, and Gambia all appear within the 10 lowest averages.
