Term used to identify individuals with an IQ
in the 98th percentile.
Generally taken as a synonym of Genius
when it is actually a lesser term (genius denoting an IQ in a narrower percentile).
The Stanford-Binet IQ test is one of the most commonly-administered tests used to determine who is gifted, and who is not; Mensa International requires a score of at least 132 on it to allow a person to join the society.
