IQ tests - what they show and what they mean

What is IQ?

IQ (intelligence quotien) is a numerical measure (coefficient) of a person's intellectual abilities, obtained by passing special tests. With this coefficient, you can calculate and measure skills such as logical thinking, analysis, problem solving, abstract thinking, and quick learning.

The history of IQ research began at the end of the 19th century when people began to create the first tests in history to measure the indicator of thinking. The popularity and distribution of such tests came in the 20th century. One of the most famous IQ tests is the Stanford-Binet test, which was created by the American psychologist Lewis Terman in the early 20th century. And in 2002, British psychologists Richard Lynn and Tatu Vanhanen published the book IQ and the Wealth of Nations. The book provides quantitative statistics of mental performance for all time for the population of 81 countries.

The results of IQ tests are represented by a coefficient that is compared with the rest of the normative data for a certain age group. Scientists say that the average IQ score is usually 100, and most people have an IQ score between 85 and 115. Scores above 130 are often considered high intelligence, while scores below 70 may indicate low intelligence. Read more about the values and their definitions below in the material.

In addition to IQ, soft skills are an important component of personality. You can upgrade them in courses from the tutortop website: “Soft skills for a leader” from Eduson Academy, “Soft skills for a leader” from the Moscow Business Academy and “Soft skills for women leaders” from Eduson Academy.
The David Wexler test is one of the most well-known and widely used tests for measuring IQ. There are two main versions of the Wechsler tests: WAIS (Wechsler Adult Intelligence Scale) and WISC (Wechsler Intelligence Scale for Children), each designed for different age groups.
