James, for some reason I keep thinking you're Matt Casey when I glance at your avatar.

I would guess your IQ is very high, just from what I've read of yours on this forum. As far as I'm concerned, a penchant for clever and creative writing is as good a judge as any.
I don't know much about the tests. AFAIK, there are different tests with different ceilings, and ranges.
I've seen test on which the highest score possible was a 150.
I've always been good with tests, and done well in school. However, I've made some of the stupidest fucking life choices possible. I have some of the most difficulty with basic decisions.
I don't think we(humans) really have an accurate model for analysing someone's ability to manipulate ideas to fit and understand different situations. I also think that ability changes throughout one's life for many different reasons.
Oh yeah, and this is all just
