What is an IQ?

An IQ, or Intelligence Quotient, is a score derived from a standardized test measuring your problem solving skills and overall aptitude. This score is then compared to the population as a whole to determine your level of intelligence compared to others of the same background and age. An Intelligence Quotient Test works by assessing how you overcome obstacles that are put to you to solve in relation to other people in your age bracket who took the same test. These problems are usually either in the from of written questions or visual puzzles. Unlike some other multiple choice exams, the way you come up with your solution in an IQ test is just as important as the answer you produce.

What is an IQ Test?

An IQ Test is a means to determine a person’s intelligence quotient in relation to other people of a similar age. These standardized tests are designed to measure a person’s problem solving ability, critical thinking and pattern recognition through the correct answering of a variety of questions. The questions are not about how much you know or how much you have learned; the IQ tests are meant to evaluate your inherent logic and reasoning skills. It is attempting to calculate your actual intelligence, not just how much information you can read and memorize from a text. The IQ tests are designed to measure your capacity to understand and resolve conflicts. The more creative your solution, the more intelligent you are considered to be.

What is the purpose of measuring your IQ?

We measure IQ because it is generally predictive of how smart and how successful a person will be – particularly when measuring the IQ of young people in relation to how well they will do later in life. These tests are used to evaluate a person’s potential income or aptitude for certain careers. They also assist in evaluating intellectual strengths and weaknesses, creative problem solving, and thinking under pressure. IQ test scores are used for educational placement in schools, admission to certain high intelligence groups and societies like MENSA, and also for evaluating applicants for specialized jobs.

What IQ score do you need to be considered a “genius”?

To be considered a genius you would need to achieve an Intelligence Quotient score of 160 or above, with anything over 130 seen as a “high intelligence” score. The IQ score for most people is about 100 on average with the majority of the human population falling somewhere between 85 and 115.

What is MENSA and how can you qualify for admission to a High IQ Society?

High IQ Societies like MENSA limit their membership to include only individuals who have scored in the 98th percentile on an acceptable Intelligence Quotient Test.

MENSA is the largest, oldest and most renowned high intelligence society in the world. It is also incredibly difficult to get into. To qualify for membership to MENSA, you must score in the top 2% of all people taking an approved intelligence or aptitude test. This sole requirement is usually met with an IQ test score of approximately 130 or above. Eligible candidates for MENSA membership need to supply proof of their qualifying test scores and pay applicable membership dues to join.
