IQ test online

Those tests are far too long. I have better things to do.

Introspect

But one's ability to remember facts is a cognitive ability, and so a greater ability should represent a greater degree of intelligence, as it does in most theories of intelligence that I'm aware of.

Actually IQ is generally quite stable over time, even in children who are growing and learning more than adults usually do. There are references that I could provide but I'm not allowed to post them yet :p

The tough part about online IQ tests is that all too often they attempt to measure knowledge, not intelligence. Likewise, as many people have mentioned here, they do skew the results in many cases to please the audience. After all, no one wants to hear that he/she is below the average IQ or even that he/she is average.

These tests are not usually accurate, but they can psychologically affect people as the people who are told that they are smart will begin to act the part that they will think that they are. It is possible that they will even belittle their peers. On the opposite side, when people believe that they are dumb because they are told such, they too will act the part. It is called the self-fulfilling prophecy.
