Intelligence quotient, more commonly referred to as IQ, is a measure of an individual’s intelligence, sanity, and acumen. The use of IQ for measuring intelligence is not the first of its kind. Numerous other tests, most notable of which include the Stanford-Binet Intelligence Scale and the Wechsler Adult Intelligence Scale (WAIS), also serve the same purpose. It is the prowess of IQ, owing to which humanity has been successful in understanding the creation of the universe, splitting the atom, making leaps and bounds in technology, and planning on settling on other planets.

Needless to say, it is this significance of high IQ which has promoted countries with high IQ to succeed and govern the market share in various fields. However, despite the correlation between IQ and per capita income, it is to be kept in mind that there are various exceptions in the list of smartest countries. On the one hand, industrialized and high-income nations such as Canada, the United Kingdom, and the United States are among the top achievers; however, on the other hand, countries such as China and Mongolia are also among the top performers.

The idea of categorizing a nation based on a single score is highly controversial and may seem downright erroneous. Intelligence, like all the other human traits, is influenced by various national, political, geographical factors. IQ has been shown to vary with education, premature birth, nutrition, pollution, drug and alcohol use, mental illnesses, and disease. Similarly, research has been successful in emphasizing a correlation between spiritual connection and intelligence. Another research highlighted the significance of iodine intake on enhancing mental and psychomotor development. One of the human emotions, most often linked with the intelligence quotient is the emotional quotient (EQ). An emotional quotient or intelligence refers to an individual’s capability of being aware and in control of his/her emotions. It also encompasses the tendency to take feedback, handle it positively, and manage interpersonal relationships more empathically. As per recent research, EQ has been shown to have a direct relation to IQ.

Our Methodology

Determining IQ and utilizing it for policy formulation and decision-making is easier said than done. The complexity of the human brain coupled with the intricate thought structure and consciousness makes it extremely difficult, if not impossible, to measure the true intellect of an individual. Different IQ tests have different formats to emphasize various aspects of the human brain and acumen. The most commonly used IQ test i.e., Mensa IQ test measures an individual’s intellect based on verbal as well as non-verbal abilities such as verbal comprehension, perceptual reasoning, working memory, and processing speed. The IQ test has been adopted to a mean value of 100 points. For a standard deviation of 15%, a score between 85-115 is considered normal. A score greater than 130 is considered super intelligence, whereas a score between 70 is of concern.

To sort the countries regarding intelligence, the reliance on only the standardized test scores can be a tricky and somewhat faulty logic. For this purpose, along with the standardized test score, the number of noble prize winners per nation and the “education attainment” are to be considered. The number of noble prize winners serves to provide empirical, historic proof to our ranking whereas the education attainment aims to illustrate the percentage of students achieving advanced scores at the school level. The data for the intelligence quotients of various countries have been taken from the latest World Population Review and the PISA tests conducted in 2003, 2006, and 2009. The stats for national incomes and average educational expenses have been taken from World Bank’s data collected from between 1990-2010. The figures for the number of noble prize winners and population have been taken from the World Bank.

Here, one of the main criticisms faced by IQ is to be considered. It has been debated for decades now that the IQ has been developed by West Europeans for West Europeans according to West Europeans standards. Applying the same tests to other nations having different educational settings, social strata, cultural and behavioral norms is something that introduces error and bias in the ranking.

Nevertheless, the ranking that has been developed and followed across the globe cannot be negated and needs to be considered for now.
