About IQ Tests Online

There are few quality IQ testing sites that provide IQ tests which mirror the conditions of the real Mensa IQ test. IQ-Brain.com is a pioneer in providing challenging but realistic IQ test questions that mirror the level of difficulty that would be expected to be encountered on a proctor-administered Mensa IQ test. Further, IQ-Brain.com allows users to take the equivalent of a Mensa IQ test online, albeit from the comfort of their own home. This provides an opportunity to practise before registering to take the physical Mensa IQ test or any similar high IQ society test.

Most high IQ societies require proof of IQ prior to joining the society. IQ-Brain.com provides Mensa IQ test online practice conditions which not only serve as great preparation for the live test, but the IQ-Brain.com tests are also accepted by a number of high IQ societies in their own right.

2% of the population is expected to have an IQ score of 132 (16 SD), which means that a large number of test takers who have attempted our fluid intelligence tests would be expected to quality for this prestigious IQ test society.

However, our IQ tests measure IQs up to 148, which corresponds to a percentile of 99.865% (16 SD), and represents a rarity of 1 in 741 people. In other words, our IQ tests can measure fluid intelligence at the “genius” level; many of our test takers would be eligible for adminission into high IQ societies with a much more stringent admission criteria than Mensa. Although few people will score highly enough to qualify for admission in to a high IQ society, our Mensa IQ test online will provide a reliable estimate of your IQ score.

Whether you are of high, average of low intelligence, your can take our IQ tests to find out more about your strengths and weaknesses and you search our site for resources on cognitive training for chance to raise for IQ test performance. Engaging in the appropriate lifestyle and training can help boost your cognitive processing power and well as your IQ test results.Try our Mensa IQ Test online today.

Intelligence test

Since its birth in the late 1890s, IQ as a concept and intelligence testing generally have been subject to a laundry list of criticisms. Here is a sample of what critics have asked:

  • What does IQ really mean and does it have any practical value?
  • How valid are the different tests and what do these tests really measure?
  • Are IQ tests culturally biased, therefore favouring some ethnic groups over others?
  • Are IQ tests gender neutral?
  • Does IQ testing have any validity?

All IQ tests suffer from limitations, although “culture fair” testing addresses several prior concerns for psychological testing:

IQ testing challenges

IQ is a proxy measure of someone’s General Intelligence (G) or cognitive ability. IQ is an imperfect, yet highly valid concept in psychological testing. Although intelligence can be compartmentalised into several aspects, the Horn & Cattell school of thought is that General Intelligence .

(G) can be dissected into two principal components: (1) fluid intelligence or “Gf” and (2) crystallised intelligence or “Gc“.

Cattell-horn breakdown of Spearman’s G

Fluid intelligence is associated with simultaneous or holistic processing and the right hemisphere of the brain. Crystallised intelligence is related to sequential processing and the learned component of intelligence, acquired largely in formal education.

Intelligence testing and test characteristics

Intelligence testing is more akin to an advanced art rather than a hard science. There is no perfect test to measure G, and one type of test will be better at measuring some aspect of general intelligence than another. Culture-fair IQ tests [e.g Cattel Culture-Fair IIIa or Raven’s Progressive Matrices (RPM)] are particularly good at measuring fluid intelligence or  imultaneous processing (as opposed to sequential processing), which is the aspect of human intelligence that is believed to be innate and which begins to decline by the time we reach our mid-to-late 20s (in the absence of cognitive training). Fluid intelligence is linked to the ability to solve novel problems as you will encounter on our culture-fair tests.

Biases in Testing

Some intelligence tests are culturally biased , particularly if they rely heavily on general knowledge, or fluency of a spoken or written language. Clearly, native speakers or individuals with higher education in the language of the test will be advantaged when taking such tests. In addition to being biased, these types of tests are often poor when it comes to measuring fluid intelligence. This is why Culture-Fair tests measuring fluid intelligence (Gf) represent a more valid concept when it comes to ‘universal’ or ‘global’ IQ test. Matrix-based fluid IQ tests are particularly relevant in the context of a borderless, web-based cohort of test takers. Mensa and other high IQ societies recognize the importance of testing fluidc_headingministration of a culture-fair IQ test.

Cultural improvements in psychological testing

Similarly, culture-fair IQ testing addresses any accusations of gender bias in testing

Mensa culture fair tests

IQ tests have been shown to have good validity, with IQ test results being statistically significantly correlated to a number of variables which are associated with intelligence.

A number of high IQ societies such as Mensa will provide two types of IQ tests to evaluate the IQ and general intelligence of test takers. A culture-fair fluid IQ test is usually administered, in addition to a verbal IQ test which measures crystallized intelligence. A passing score on either section of the test (IQ of 132 or more, if SD=32) will result in the test taker extended an invitation to join Mensa.

As a final remark, it is quite possible to have low or modest fluid intelligence (” Gf “) and to have average or above average crystallised intelligence “Gc“, or vice versa. However, higher fluid intelligence makes it easier to ‘invest’ in one’s crystallized intelligence (enhanced through education). Click here to TAKE OUR CULTURE FAIR IQ TEST.
