>If not, do you think your friends or family are all better than the general population?

Since most people live in social bubbles that would be a very plausible case, especially on HN.

If you're a college educated developer, with a college educated wife, and smart, well educated children, perhaps yourselves the children of college educated parents, and your social circle/friends are of similar backgrounds, you'd of course be "better than the general population".
