IQ
So, my wife was identified as high IQ (gifted) back in grade school. She has an IQ in the 130s.
Meanwhile, I was overlooked by the system. I'm not sure why, but a variety of possible reasons for this, such as different school systems (I was in California while she was in the Midwest), my grades weren't always stellar in grade school because I got bored, etc.
So maybe my wife is substantially smarter than I am. We can't know without me taking an IQ test.
What would you do in my situation?
