An IQ In The Top 2%

Getting into Mensa is NOT EASY. You have to score at or above the 98th percentile – the top 2% – on a standardized, professionally administered IQ test. This is typically a score of 130 or more. What does an IQ score of 130 mean?

.

The IQ Score Bell Curve

With standardized IQ tests, IQ tests are designed so that their scores have a ‘bell curve’ distribution in the general population with an average of 100.  This curve has a peak in the middle where most people score and tapering ends where only a small percentage of people score. In statistics this distribution of scores is called a bell curve or normal distribution – as shown below.

 

IQ bell curve

Standardized IQ tests are designed so that the exact average (mean)  IQ score in the general population is 100.  An ‘average IQ score’ or ‘normal IQ score’ can be defined as a score between 85 and 115. 68% of people score between 85 and 115.

The Mensa qualifying IQ score is a score that puts you in the top 2% of the population in a bell curve like this one. The Mensa qualifying score is 130 or higher, as shown below.

How To Test Your IQ? Mensa Accredited IQ Tests

Standardized IQ tests accepted for Mensa membership are administered by school districts (e.g. the Cognitive Abilities Test (CogAT)), private psychologists (see below), the military (e.g. Army GCT) and human resource departments (e.g. the Wonderlic). There are two broad types of intelligence test:

1. ‘Full-scale’ IQ tests, made up of subtests for fluid intelligence (Gf) as well as vocabulary and general knowledge, visuo-spatial ability, short term memory, and processing speed. Sometimes quantitative/mathematical reasoning is also tested in ‘full scale’ tests.  A popular example is the WAIS-IV IQ test. For more on the definition of general intelligence and 5 factors of IQ click here.
2. Culture-fair tests of fluid intelligence. Fluid intelligence is our ability to reason and problem solve, independently of familiarity, training and practice. These test a component of your intelligence called ‘fluid intelligence’. A popular example is the Raven Advanced Progressive Matrices test.

Mensa accepts scores from approximately 200 different standardized intelligence tests (click for qualifying test information here). Some are fluid intelligence tests. Some are full-scale tests.

 

 

 

The Mensa Admission Test

A cost-effective method of measuring your true IQ level is to take a Mensa supervised test – $40.00 in the US /  £17.50 in the UK.  This fee includes:

American Mensa offers two test batteries by Mensa proctors, that may qualify you for membership. The first includes both the Mensa Admission Test and the Mensa Wonderlic^®; this is the battery of tests given most frequently. This is a full-scale IQ test. The second battery is a “culture fair” battery that includes the Cattell Culture Fair, the Nonverbal Reasoning Test and the SRA Pictorial Reasoning Test. This is primarily a fluid intelligence test. Mensa Supervised test sessions are held at centres throughout your home country. Click here for details from International Mensa. For those in the US click here. For those in the UK click here.

 

Mensa Online Practice IQ Tests

The Mensa Workout

To get you limbered up, try the Mensa Workout. This quiz is not an official IQ test to qualify you for Mensa but gives you a good idea of the range of question types involved in official IQ testing. The questions on the “Mensa Workout” are biased towards people whose primary language is English. You have half an hour to answer 30 questions.

 

.

The Mensa Practice Test

Alternatively you can take the online Mensa Practice Test for $18. As explained by American Mensa:

The Mensa Practice Test is a fun way to discover if you are Mensa material. While this timed test will not qualify you for membership, it does offer an equivalent score that correlates to your IQ range and provides a strong indication of your likelihood for success should you choose to take our admission test. For only $18, you can take the Mensa Practice Test online now, and it will be scored immediately.

 

Other Online Practice Tests

The GIQ Test

The GIQ test  will give you a good standardized estimate of your ‘full scale’ IQ – combining fluid intelligence (non-verbal) and verbal problems. The fee is $10. According to the test-makers:

The GIQ Test is an online analog for the most common clinically proctored IQ tests. In our internal study, the GIQ Test correlated within about 4% of an individual’s full scale score on a clinically proctored IQ test. The GIQ Test’s sections are modeled after clinical IQ test sections.

The GIQ has the following features

• Time required: 25-45 minutes estimated. No time limit.
• Components of intelligence measured: full scale intelligence, ‘verbal’,  ’spatial’ and ‘quantitative’ intelligence. Your performance sub-score on this test can substitute as a measure of your fluid intelligence.
• Culture fair IQ test? No. Vocabulary, similarities and arithmetic subtests are culture-dependent.
• Fee: $10

.

The iqtest.dk

This is a fluid intelligence test of culture-fair reasoning and problem solving skills. It is similar to the ‘culture fair test battery’ alternative for Mensa qualifying tests. As explained on the iqtest.dk website:

This test is developed with the aim of measuring your Intelligence Quotient (IQ). The test is Culture Fair, i.e. it minimises the effect of cultural variables, such as language, mathematics, etc. The test is based on logic, but is furthermore designed to test learning capability, memory, innovative thinking and the ability to simultaneously address several problems. The test measures the general intelligence – g.The calculation of IQ is based on answers from more than 250,000 people.

In this test you have 40 minutes to answer 39 questions. Take the test here.

Getting Into Mensa – Training Strategies

 

An effective strategy for getting into Mensa is a combination of practice and working memory (n-back) training. Working memory training back is an evidence-based method for increasing cognitive ability through neuroplasticity change (ref). There are two general training strategies for the two types of Mensa test available (check with your Mensa provider what kind of test you will do). Both of these strategies have been used successfully by hundreds of test-takers.

 

Culture Fair (Fluid Intelligence) IQ Test Strategy

As noted above, Mensa accept two types of officially administered IQ tests: those that measure fluid intelligence (your abstract reasoning and problem solving skills), and those that measure all subfactors of your intelligence, including verbal and quantitative intelligence – called ‘full scale’ tests. They have a Mensa Admission Test for both. For a fluid intelligence strategy I suggest the following:

1. Take the free iqtest.dk. This will give you a good estimate of your current IQ level. Take a note of your score. If it is 115 or higher, with the right preparation and training you have a good chance of attaining a qualifying score of 130 on a Mensa accredited IQ test for fluid intelligence.
2. Schedule a month in advance a professionally administered fluid (culture-fair) IQ test such as the Raven Advanced Progressive Matrices (RAPM) or the Cattell Culture Fair III IQ test with a local psychologist or educationalist. Alternatively, inquire with your local Mensa society whether you can take a ‘culture fair’ admission test. Culture fair tests are essentially fluid intelligence tests.
3. Leading up to your qualifying IQ test, commit to training your working memory capacity. Working memory capacity  is your mental ‘workspace’. The larger the capacity, the more complex reasoning and problem solving you can do. There is a body of scientific evidence showing that working memory training can have widespread benefits for IQ and cognitive performance (review or journal article).  The evidence-based i3 Mindware cognitive training app has been designed to expand working memory capacity and increase IQ level by 10-20 points. There is a money-back guarantee if you do  not attain this IQ gain based on standardized IQ tests before and after training. Evidence shows that IQ level is not fixed, and can be improved with training long term.
4. Leading up to your qualifying IQ test, commit to training your IQ problem solving strategies. Practice on fluid intelligence IQ tests, such as found here on SmartKit. The i3 IQ increase software also incorporates systematic tutorials on problem solving skills and strategies, designed by cognitive scientists.
5. There are other lifestyle practices you can adopt over this period to increase your IQ. These include regular exercise, a brain-optimizing diet, meditation and unbroken, regular sleep.
6. After completing the IQ training program if you have chosen it, allow for at least two days of training consolidation before taking the qualifying IQ test.
7. Take the official Mensa test.
8. Join Mensa.

 

Full Scale IQ Test Strategy

 

1. Schedule a month in advance a Mensa accredited full scale IQ test. Click here for details from International Mensa. For those in the US click here. For those in the UK click here. Ensure that you establish that the test is ‘full scale’ – including verbal and quantitative problems.
2. Take the Mensa Workout.
3. Take the Mensa Practice Test  (see above).
4. Take the GIQ Test (see above).
5. All these practice tests will give you a good estimate of your current full scale IQ level – the type that is tested on the standard Mensa Admission test.
6. Leading up to your qualifying IQ test, commit to training your working memory capacity. For a full-scale test, we recommend the i3 Mindware cognitive training app has been designed to expand working memory capacity and increase IQ level on full-scale tests by 10-20 points.
7. Leading up to your qualifying IQ test, commit to practicing full scale IQ test problems.  The i3 Mindware IQ app has been designed to systematically give users practice on full scale IQ test problems.  This kind of targeted practice can improve scores on full scale tests.
8. As in the fluid intelligence only strategy, there are other lifestyle practices you can adopt over this period to increase your IQ. These include regular exercise, a brain-optimizing diet, meditation and unbroken, regular sleep.
9. After completing the i3 Mindware training program if you have committed to this training, allow for at least two days before taking the qualifying IQ test.
10. Take the official test.
11. Join Mensa!

Advantages of being a Mensa member

Mental stimulation

You can find intellectual resources to exercise your brain in national magazines, in local newsletters, and at regional, national and international conventions. Mensans (Mensa members) have a profusion of special interest groups. To quote from Mensa International:

Whatever your passion, there’s almost certain to be a Special Interest Group (SIG) filled with other Mensans who share it! Mensa offers approximately 200 SIGs, in mind-boggling profusion from African Violets to zoology. Along the way you’ll find microbiology, and systems analysis, but you’ll also find Sherlock Holmes, chocolate and Star Trek. There are the expected: biochemistry, space science, economics — and the unexpected: poker, roller-skating, scuba diving, UFOs and witchcraft. There are SIGs for breadmaking, winemaking, cartooning, silversmithing, and clowning. Heraldry, semantics and Egyptology co-exist with beekeeping, motorcycling and tap dancing. Sports SIGs cover the classics (baseball, basketball, and football) and the not-so-classic (skeet shooting, hang gliding, skydiving). And any Mensan who can’t find a SIG to join can easily start one.

.

Social life

Local groups meet monthly or even more regularly. There are widely attended annual conventions offering workshops, seminars, and parties.

.

Mensa members publications

You will receive your national magazine with contributions by Mensans on a wide variety of subjects. In some countries, in addition to the national magazine you may receive lively local newsletters. Mensa also publishes it’s own research journal on IQ related topics – The Mensa Research Journal – for the general public.

.

Career

In some countries Mensa sponsors a members-only credit card and insurance program. There is also a program that aids traveling Mensans. There have been reports that job applications have been easier with Mensa membership on your CV – particularly if the hiring person is also a Mensan.
