Well, that may be true to an extent. The other day I was working with some code that was adequate for most purposes, but didn't meet my rigorous standards (hence: attention to detail and thinking through every aspect of the issue).

So I put on my "old age and treachery" hat, aka my puzzle solving hat, and came up with a better solution one that was:

shorter

simpler

more robust

The experienced programmers I know call this cheating, hence the "old age and treachery" (from "old age and treachery beat youth and beauty every time").

Smarts, puzzle solving and intelligence are all a critical part of that. And that's the thing that is the 10x multiplier that makes all your 'average' (median) programmers look distinctly below 'average' (mean).
