Can You Answer These Thoughtful IQ Questions Correctly?
There's no such thing as "an" IQ. You have an IQ at a given point in time. That IQ has built-in error. It's not like stepping on a scale to determine how much you weigh.

The fluctuations in IQ were enormous. I'm not talking about a couple points, but 20-plus IQ points, one way or another. These changes in IQ scores were not random — they tracked very nicely with structural and functional brain imaging. Suppose the adolescent's verbal IQ really went up during that time; it was verbal areas of the brain that changed.

There are quite a large number of other studies showing IQ can change. Many of the changes in IQ are correlated to changes in schooling. One way that school increases IQ is to teach children to "taxonimize," or group things systematically instead of thematically. This kind of thinking is rewarded on many IQ tests.

There's also a number of studies showing that the brain changes after several kinds of regimen. London Taxi drivers whose brains are scanned before and after they start driving, and learning to navigate London's maze of streets, show changes in the brain as they use more navigational skills. Even young adults who take a juggling course show brain changes.

If you put it all together, and the evidence is quite compelling, that life experiences and school-related experiences change both the brain and IQ. This is true of adults and children. Can you answer these IQ questions using only your mind? Don't use Google or pen and paper. Give it a shot!
