My take on it is that I know parents who have bright children, but who believe their children are, in fact, gifted. They are walking bubbles of cognitive dissonance-you can't tell them their kid's not brilliant, and they have excuses for every result that doesn't show giftedness.

I'm assuming these people are going to be taking your test, as well. In some social circles, having a smart kid is a status symbol.

But maybe it's not enough to skew the results appreciably.
