Multiple such individuals (of the latter category) are on record. I linked originally to a woman with an IQ of 230.
Such scores have been issued, but are widely regarded as nonsense, and Marilyn Vos Savant’s 200+ score is no longer given credence in the record books. The old formula (mental age divided by chronological age x 100) allowed for a number of individuals with scores over 200, and did not allow for negative scores, but it was flawed in many ways and has been discarded, and no individual has received a score over 200 from a proper application of the IQ test since then.
This is tiresome: 100 is average, and 0 is non-intelligent, and we do still need the definitional standard of the standard deviation. For the same reason that we also have a specific object that masses one newton. It’s how the quantification is defined.
Show me where such a definition is laid out.
Deviation measurements and absolute measurements both serve their purposes, but we don’t have any absolute measurements for intelligence. The IQ test is not and was never intended to be an absolute measurement of intelligence in the way that newtons are a measurement of force. Comparing IQ to temperature, it’s like defining the average particle kinetic energy in a vessel to be 100, with one standard deviation in kinetic energy being 15, without knowing what the temperature inside the vessel is.
