It seems to me that the IQ tests we were administered in our youth turned out to be very, very predictive...as did the SATs and other standardized tests. At least for those I am familiar with. Of course, I imagine having high scores or doing well on tests likely influenced other behaviors. They did not disclose IQ scores to children when/where I grew up...so you did not really know how well you did on those until you were older. I did not know my score until I was a senior in high school. Too late to influence my expectations/direction (based on knowing my IQ). Of course, other standardized tests (showing what you had learned) affected placement.

I realized they have adjusted standardized tests greatly over the years... likely because the scores did not seem to say what they wanted them to say.
