Here is a list of famous people with high IQ's. The IQ scores featured here were estimated from The Calculated IQ Estimates for 301 Historic Geniuses which was published by Catherine Cox Miles, American Psychologist, which is also also known as The Early Mental Traits of Three Hundred Geniuses.
IQ stands for ‘Intelligence Quotient’ and is a numerical score based on standardised tests which attempt to measure intelligence. Although it originally referred to the first intelligence scale, developed by French psychologist, Alfred Binet, to measure mental ability in children, it is now used in conjunction with several intelligence scales and is a considered a general indicator of intelligence.
However, not all intelligence can be measured by an IQ test. In fact, primarily, an IQ test measures mathematical and spatial reasoning, logical ability, and language understanding. Thus a person who is speaking English as a second language might score poorly on the language comprehension aspects of a test, and an IQ test would not be an adequate measurement of intelligence.
