Top 13 People With Highest IQ in the World

The definition of Intelligence is debatable, or we can say that there is no exact words defining the term ‘Intelligence’. Over the years, it has been defined in many different ways, including one’s capacity for logic, understanding, self-awareness, creativity and problem solving.

Intelligence quotient (IQ), on the other hand, is just the outcome or score obtained from one of the many standardized tests to measure human intelligence. Our interest in human intelligence dates back thousand of years, but it was not until the 20th century that the first IQ test was ever devised by Alfred Binet. Since an individual’s intelligence is measured by a set of tests, the method has been condemned by many.

In his book, ‘The Mismeasure of Man’, paleontologist Stephan Jay Gould criticized IQ test on general bases and said they are used for scientific racism. So we can say that IQ is just a parameter to nearly measure human intelligence which can be useful sometimes and sometimes it is not. In this list we have gathered the brightest and smartest people who ever put foot on the earth based on their IQ score.

Estimating the exact IQ of one of the greatest scientific minds of the 21st century is indeed a serious affair, as Hawking never took one. Among his many scientific achievements, he is also known for his book A Brief History of Time, published in 1988, which portrayed his brainstorming discoveries in the field of theoretical physics. Hawking’s contributions in the ancient field of theoretical physics have not only revolutionized the field, but also fairly contributed towards the advancement of the sum of human knowledge substantially.

10. Albert Einstein

IQ score: 160-190

Experts and neuroscientists have estimated Einstein’s total IQ somewhere between the range of 160-190. Again, these numbers are nothing more than an estimation.

His theories reshaped scientific understanding of almost everything including space and time. He also indirectly or subconsciously participated in developing nuclear fission, an endeavor which he later regretted when it was weaponized in the form of an atomic bomb. He died in 1955 from an abdominal aortic aneurysm.

William James Sidis is a perfect example of child prodigies with exceptional mathematical abilities and a master of many languages. At the early stages of his career (when he was 11), he entered Harvard to study mathematics, and became the youngest person to achieve so. The rest of his life was marred by legal troubles due to his socialist ideology, and was arrested for participating in an anti government parade.

Upon his release in 1921, the troubled genius stepped away from mathematics and academics entirely, and lived a relatively normal life. He died at the age of 46 from a cerebral hemorrhage. It is claimed that Sidis had the highest IQ that can ever be achieved, but any records does not exist which proves the claim.
