That's right. IQ.
Now that the other predictable thread is under way (this is my first time I glanced at it), it got me wondering what exactly an IQ test shows. What part of general intelligence? Is there a real general all-encompasing test that can probe all different parts of the human intellect?
To be able to quickly access and evaluate different parts of memory, triggered by different causes; to grasp different types of concepts; to solve them; intuitive logic. I'm not sure I've seen these very well quantified.
