I've always thought I'm not a genius by any means, but probably a bit above average intelligence, but it occurs to me that most people think of themselves that way and there's a good chance we're deluded!
50% of us must be less intelligent than average. Do the 50% know?
I find that people normally manage to find a reason outside of themselves (poor opportunities, bad family, bad school, bad health etc) for any low levels of accomplishment. Not many people will say they just weren't capable of better, even with all the help in the world.
So, do you consider yourself a thicko? Does anyone?
