IQ of a genius

Answer 1

It is not the numerical value (for example, 140) of the IQ test that matters, but rather the percentile (usually above the 98th) and the standard deviation (usually two standard deviations) that indicates potentially superior intelligence. The numerical score on one IQ test does not even have the same meaning as the same numerical score on a different type of IQ test. For example. An IQ score of 140 the Cattell Culture Fair IQ test is only equal to a score of 125 on the Wechsler (both are very strong scores).

The consensus in the field of psychology is that a score of two standard deviations above the norm (roughly higher than 95 to 98 percent of the population) is an indication of very superior intelligence. Sometimes the word "gifted" is used. Scoring significantly higher than two standard deviations above the norm is basically meaningless. To accurately measure intelligence beyond two standard deviations above the norm requires a deeper analysis by an expert in the field of psychology specializing in psychometric analysis.

Again, whether or not someone is actually a "genius" requires a more careful psychometric study of an individual's intellectual strength (mathematical, spatial, linguistic, pattern-solving, etc.). Though the belief is often held by lay persons and children that IQ tests are "genius detectors", no IQ test can honestly indicate if someone is actually a genius. Scoring the same on an IQ test as Stephen Hawking does not make you as smart as Stephen Hawking.

IQ tests are not without limitations. Unfortunately, in some instances high IQ scores are actually more of an indication of a person's familiarity with IQ tests and not the individual's real intelligence level. IQ tests are also academically loaded to some degree, resulting in persons with less access to academic resources during their lives having artificially lower scores than persons with greater access. An individual's score may also vary (usually by about ten points) depending on diet, stress, level of sleep, etc.

The IQ of a genius is 140 and up. If you are in 140 or 150s, you are kind of and almost a genius. If you are higher, YOU ARE A GENIUS! (This statement is not correct. See the explanation above.)
