<p>Really, though, what is the purpose of IQ testing? I am skeptical as to whether something as intangible and multi-faceted as human intelligence can be expressed as a numeric value. IQ testing seems to me to be an industry catering to vanity and insecurity.</p>
<p>They sell IQ test booklets (from MENSA, I believe) at Barnes and Noble. They're cheap, and seem accurate enough. Of course, IQ means next to nothing in today's society (and frankly, I like it that way.)</p>
<p>Nope, online IQ tests aren't dependable at all. If you want to try a more accurate one, you can pick up one of those booklets published by MENSA at the bookstore for $5 or get MENSA to test you for $40. If you're serious about it, you can have a psychologist test you, also.</p>
<p>Online tests are not particuarly reliable,nor are the ones sold in book stores. The ones Mensa allows potential members to take are somewhat reliable, but for a really accurate score you need to be tested by a professional. In general, you will actually get a set of scores in various areas of intelligence which are combined into a single number.
What, really, that number signifies is the subject of considerable debate, however the tests themselves are fairly consistent, particularly in the middle of the bell curve.</p>
