Who holds the record for the highest IQ of all time? While intelligence is a complex and multifaceted trait that cannot be fully captured by a single number, several individuals are often mentioned in discussions about exceptionally high IQ scores. One of the most frequently cited names is William James Sidis, whose estimated IQ ranged from 250 to 300. However, it’s important to note that accurately measuring such high IQs is challenging and often speculative.
What is IQ and How is it Measured?
Intelligence Quotient (IQ) is a standardized score derived from a set of tests designed to measure human intelligence. The average IQ is set at 100, with most people scoring between 85 and 115. IQ tests assess various cognitive abilities, including logical reasoning, problem-solving, and understanding complex ideas.
Factors Influencing IQ Scores
