Who are the smartest people in the world? How do they achieve such high levels of intelligence? What are their secrets to success?

In this article, we will explore the top 10 smartest people in the world, based on their estimated IQ scores, and reveal some of their secrets to becoming so smart.

What is IQ and how is it measured?

IQ stands for intelligence quotient, which is a measure of one’s cognitive abilities relative to the average population. IQ tests are designed to assess various aspects of intelligence, such as verbal, mathematical, spatial, and logical reasoning skills. There are different types of IQ tests, such as the Stanford-Binet Intelligence Scale, the Wechsler Adult Intelligence Scale, and the Peabody Individual Achievement Test. However, there is no single standard or definitive IQ test, and the scoring methods may vary across different tests and versions.

The average IQ score is set at 100, with a standard deviation of 15. This means that about 68% of the population scores between 85 and 115, and about 95% scores between 70 and 130. An IQ score above 130 is considered very high, and an IQ score above 140 is considered genius or near-genius level. However, IQ scores are not absolute or fixed measures of intelligence, and they may change over time due to various factors, such as education, environment, motivation, health, and age.
