The highest recorded IQ in the world belongs to Marilyn vos Savant, an American magazine columnist, with an IQ of 228. Intelligence quotient, or IQ, is a measure of cognitive ability and potential. It is calculated based on standardized tests that assess a range of skills including memory, problem-solving, and reasoning. Although IQ is not the sole indicator of a person's intelligence or success in life, it remains a widely used and accepted method of evaluation. The person with the highest IQ in the world is a testament to the limitless potential of the human mind and serves as inspiration to push our own limits and strive for personal and intellectual growth.
