What IQ ranges are considered smart and genius?

Answer 1

Intelligence testing began in earnest in France, when in 1904 psychologist Alfred Binet was commissioned by the French government to find a method to differentiate between children who were intellectually normal and those who were inferior. The purpose was to put the latter into special schools. There they would receive more individual attention and the disruption they caused in the education of intellectually normal children could be avoided.

This led to the development of the Binet Scale, also known as the Simon-Binet Scale in recognition of Theophile Simon's assistance in its development. The test had children do tasks such as follow commands, copy patterns, name objects, and put things in order or arrange them properly. Binet gave the test to Paris schoolchildren and created a standard based on his data. Following Binet’s work, the phrase “intelligence quotient,” or “IQ,” entered the vocabulary.

Lewis M. Terman worked on revising the Simon-Binet Scale. His final product, published in 1916 as the Stanford Revision of the Binet-Simon Scale of Intelligence (also known as the Stanford-Binet), became the standard intelligence test in the United States for the next several decades. By the 1920s mass use of the Stanford-Binet Scale and other tests had created a multimillion-dollar testing industry.

Despite the fact that the IQ test industry is already a century old, IQ scores are still often misunderstood. Comments like, “What do you mean my child isn’t gifted — he got 99 on those tests! That’s nearly a perfect score, isn’t it?” or “The criteria you handed out says ‘a score in the 97th percentile or above.’ Susan got an IQ score of 97! That meets the requirement, doesn’t it?” are not unusual and indicate a complete misunderstanding of IQ scores.


Understanding IQ Scores


IQ stands for intelligence quotient. Supposedly, it is a score that tells one how “bright” a person is compared to other people. The average IQ is by definition 100; scores above 100 indicate a higher than average IQ and scores below 100 indicate a lower that average IQ. Theoretically, scores can range any amount below or above 100, but in practice they do not meaningfully go much below 50 or above 150. Half of the population have IQ’s of between 90 and 110, while 25% have higher IQ’s and 25% have lower IQ’s:

130+
Very superior
2.2%

120-129
Superior
6.7%

110-119
High average
16.1%

90-109
Average
50%

80-89
Low average
16.1%

70-79
Borderline
6.7%

Below 70
Extremely low
2.2%

I took a real IQ test administered by a professional. It wasn't taken online. Most online IQ tests aren't very accurate at all. My IQ is 126 which is considered to be above average for my age. I'm 16. When I took various online IQ tests, my scores were in the 140s range. An IQ of 140 is considered to be near genius. I believe 90-109 is average, 110-119 is high average, 120-129 is superior, and 130 and above would be very superior. Not many people have an IQ above 140. When I took my test, my results were in extensive detail. If you would like to know what your actual IQ is, you'd have to pay for it and have it administered by someone who is qualified.
