The number shows how your performance compare to those of others your age. A score of 116 or more is regarded as above average. A IQ of 130 or higher indicates a high level of intelligence. Mensa, the high IQ society, admits members with IQs in the top 2%, which is generally 132 or above. For many people, an IQ of 120 to 135 is very high; for others, it is lower.
An IQ of 128 is considered very high. It is similar to the average IQ scores of other highly intelligent individuals. Such people are often called geniuses because they show extraordinary ability in one or more areas of knowledge or creativity. In general, these people are also highly creative and productive in their work. They may have some physical disabilities or be slightly deaf, but this does not prevent them from being brilliant scientists, artists, or musicians.
People with IQs between 107 and 115 are usually diagnosed with mild mental retardation (MR). This means that they have impairments in both intellectual ability and adaptive behavior. These people usually have problems with attention and focus, controlling their behaviors, and managing daily tasks. They may also have difficulties with reasoning and problem-solving skills. Although they can learn information, retain what they learn, and answer questions correctly, they cannot perform complex tasks without help from others.
People with IQs between 92 and 106 suffer from moderate MR. They can understand instructions but may not remember them.
The average test score is 100, and anyone who achieves a score of 132 or above (the 98th percentile) on the Mensa exam gets admitted to the Mensa society, an international high-IQ group. According to Mensa, an IQ of 135 to 158 places you in the top 1% of the population. So, yes, 158 is a very high IQ score.
However, not everyone who thinks they have a high IQ actually does. Many people overestimate their intelligence, often believing that they are more intelligent than other people. Also, there is no actual way to verify how smart someone is without testing them; only their IQ score can be verified through assessment. A person's self-assessment of their own intelligence is not reliable.
In addition, there are many factors other than intelligence that can affect a person's ability to succeed at anything they try. For example, someone who experiences stress when making a decision may need time to process all their options before making a choice. This would be called "making a slow decision" and it would be considered a negative trait for those who want to be successful at something.
Finally, just because someone has a high IQ doesn't mean that they will be successful at everything they attempt. Some people with high IQ scores have had difficulties maintaining employment, while others have achieved success in creative fields such as art, music, writing, and acting.
The Stanford-Binet and the Cattell IQ tests are two of the most well-known IQ tests (explained in more detail below). In practice, qualifying for Mensa in the top 2% requires a Stanford-Binet test score of 132 or higher, or a Cattell equivalent score of 148 or higher.
The Mensa website notes that while no one can predict how someone will do on an IQ test, there are some things we know about people who scored highly on these types of exams. They tend to be white, male, between the ages of 15 and 24 when they take the test. The website also notes that people who scored high on previous versions of these tests may not score as high on the new version because standards have been raised since those tests were first created.
The Mensa website goes on to say that people who make it into Mensa tend to share several other characteristics: they're very intelligent; they work with their minds instead of their bodies; they like to solve puzzles and play games; they often get bored easily so they need plenty of different activities to keep themselves interested; and they usually get along well with others who think as they do.
Mensa has chapters all over the world. If you want to join a local chapter, visit www.mensa.org/getinvolved/localgroups. You must be nominated by another member of the group to be considered for membership.
An IQ test yields a score of 100 on average. The majority of persons fall between the ages of 85 and 114. A high IQ is defined as a score of 140 or higher. A genius IQ is one with a score of more than 160. This number is extremely rare.
The highest recorded IQ score on an official test was 188, by Soviet psychologist Leonid Vitalyev. He scored that high on the Russian version of the IQ test. The lowest recorded score was 70, earned by Dementieva Tatiana Vladimirovna on her 15th attempt. She was 11 years old at the time she took the test.
Geniuses tend to have high IQ scores from early childhood. Some scientists believe that genes play a role in intellectual ability. Other people just seem to appear out of nowhere and achieve great things. There are very few cases of someone with no apparent background factors reaching genius status.
A small minority of people who take IQ tests reach the highest level of intelligence estimated to be available to humans: genius status. According to research published in 2003 by John J. O'Connell and Ronald A. Riggio of the University of Texas at Austin, there are about 3,000 geniuses in the world today. That makes it unlikely but not impossible that someone could be born with the potential to become smart enough to figure out how to use physics to build a nuclear weapon.
The normal or average range of IQ is 90–110; IQ values of at least 120 are considered outstanding. Therefore, the average IQ of a seven-year-old is 100.
IQ tests usually consists of several questions that require you to identify similarities or differences between two objects or concepts. The answers are scored according to how many correct answers you give, with more points being awarded for correctly identifying more things. There are also narrative questionnaires that can be administered verbally, in which case no actual test score is obtained. These are often called "applescripts" or "audiovisuals".
The IQ test was developed by Charles Spearman who studied the intelligence of children and found that it improved as they aged. He concluded that IQ is not fixed but rather changes throughout life. Today, we know this isn't true (see reviews by Sternberg et al., 1998; Jensen 2006), but at the time there were few other ways to measure adult intelligence so his work laid the foundation for future studies.
There are many different types of IQ tests, but they all measure your ability to understand information presented in the form of pictures, words, or both.
