This betrays your ignorance. I.Q. is scaled according to age. One does not "improve."
I am new to the list, and I was going to just sit and absorb for a few weeks, but.... Yes, the IQ scale that we generally refer to is based on age, ie. a 10 year old and a 5 year old that perform equally will have different IQ scores. However, it is now generally accepted in the psychology field that your brain can degrade or improve over time based on the stresses placed upon it. Basically what this means is that your brain is like a muscle, and the more you use it, the higher your IQ becomes. Contrary to popular armchair psychology, there is no significant evidence that IQ and age are inversely related. In general, however, the older we get, the less we use our brain, and it becomes like a muscle that we no longer use. The point: Yes, you can improve your brain, and you can take proactive steps to increase your IQ. (back to lurk mode)
