The lowest IQ score recorded is technically 0/200, although no individual has ever officially scored that low.
Understanding IQ Scores
IQ, or Intelligence Quotient, is a score derived from standardized tests designed to assess human intelligence. These tests measure various aspects of cognitive ability such as:
- Problem-solving skills
- Reasoning abilities
- Memory
- Processing speed
The average IQ score is generally considered to be 100. Scores significantly below this average can indicate varying degrees of cognitive impairment. According to the provided reference, any result below 75 points is an indicator of some form of mental or cognitive impairment. While 0 is theoretically the lowest possible score on an IQ test, it has not been officially recorded in history.
