i suppose information can be useful from IQ tests. my example was a little extreme and basically i was saying that an abused child wont care about IQ tests or that this line has an A on it and this one has a B on it. It's not just that test but the thing is that in grade school is where you will learn how to perform on these tests into the future. They are all basically the same. The numbers change slightly, the patterns changed but i think that at some point you be able to associate the test content to what you already have come across. When an adult takes this test, who woukd fall into theh category referenced in the first paragraph then... blah, blah, blah...this may be a little different than what the OP is asking. On the other hand anything that measures beyond basic skills would need to take into account the learned or experence edge. My IQ varies from 50 to a little under 200.
