This is true to an extent. IQ is a very stable trait throughout one's lifetime. I have posted on this before and provided references for emprical
data. Please PM if you need them.
Variation in an individual's IQ over the lifespan also happens to some extent. What accounts for this? That is THE question.
If we knew how to raise IQ in a systematic way, I think it would be integrated into modern educational systems. The problem is that nobody knows what
is accounting for the variance in IQ scores over the lifespan.
In my opinion, IQ is only a mildly accurate indicator of the subject's intelligence, and should not be relied upon. If you desire to
increase your intelligence, which is an admirable ambition, you should attempt to learn and read and absorb as much knowledge as you are able to. Do
not rely upon such tools as the IQ test to measure your intelligence level. Learn, and keep learning. Never stop learning. Read everything you can.
Question everything. Examine everything. That is how you will increase your intelligence.
What you are suggesting is an attitude. Will this result in an increase on an IQ test? Possibly. Many IQ tests use measures of both fluid and
crystallized intelligence. While these constructs may be under some debate, there is enough data behind them to use them as real constructs in this
context. Tests that load on fluid intelligence tend to focus more on novel, speeded problem solving. Tests involving pattern recognition, such as
Raven's Progressive Matrices, are good measures of fluid intelligence. Tests that load on crystallized intelligence tend to involve factual
information (When/where/what questions). Different IQ tests will calculated IQ based on different weights of these types of intelligence.
Fluid intelligence is more likely to remain stable throughout one's lifetime. Fluid intelligence (also highly correlated with 'g') has greater
correlations with biological measures as well (body symmetry, brain glucose efficiency, neural and peripheral conduction speed) than crystallized
My advice on raising IQ? 1) Realize that IQ is a score on a test. 2) Find out which tests load IQ more on crystallized intelligence. 3) Use strategies
to memorize as much factual information as possible. 4) Take an IQ test.
Does this mean you are increasing your intelligence? Who knows. It depends on what definition of intelligence you are using. It probably won't make
any difference in your life if you try to increase IQ this way.
IQ isn't supposed to be a measure of "how much" you know, although many people seem to think that's what it is. The actual definition of IQ
depends on what test you are taking. There isn't one "IQ".
