"The human brain is unique in that it is the only container of which it can be said that the more you put into it, the more it will hold." - Glenn Doman
Over the last couple of posts I've been focusing on increasing intelligence and deviating from the main point of this site: offering free IQ tests. So, without further ado, here are some free IQ tests you can take right now. Please note that these are not your standard vanity tests on sites like tickle.com that are as accurate as a blindfolded game of darts. These are free IQ tests that have some degree of accuracy and aren't just designed to tell you you're a genius and feed your ego.
Bergmans IQ Test
This is a free application download (about 1.5mb) which will run you through a series of 20 questions which you must complete in one hour. This test has been designed to be very similar to the Mensa IQ test (more about Mensa later), and hints that it is a Mensa practice test.Questions: 36
Time: 1 hour
This site offers an online test and claims that 3 million people have already taken it. This means that the comparisons are pretty accurate. Another neat thing is that you can only take this test once per computer terminal (I assume this means IP address), meaning that there are less cheaters and results are more accurate.Questions: 30
Time: 10-15 minutes
High IQ Society
These guys claim to have calibrated their IQ test over 4 years using over 400,000 test results. Their IQ test is unique in that it selects questions from a pool of over 2.4 billion, thus virtually guaranteing that no two tests will be the same. They even admit the limits of online testing and that all IQ tests have error involved. They also invite anyone who scores 124 or over to join their society. Regardless of whether this is a motive for you or not, it's still an strong and accurate IQ test.Questions: 36
"We are confident we've created the best online IQ Test." is the caption on the front page. While that may be a dubious claim, these guys have certainly done their homework. They have a nice summary page showing how the IQ test was developed and researched. While it is free to take this IQ test, the reports and analysis will cost you $10. You may or may not want to shell out this cash. I'd recommend trying the free IQ tests first, then if you're still serious consider this one.
Time: 25-45 minutes
These tests are all either seriously calibrated or PhD certified. If you're serious about measuring your IQ then they will provide better results than the majority of free IQ tests out there, but you should also consider taking a real life, certified IQ test. While it may be a grueling and time consuming feat it will provide a result a hundred times better than any of the 5-minute, free IQ tests online.
