I hate to admit this, but I feel the same way when it comes to programmers themselves.

I've tried very, very hard to be mindful of this in an effort to correct it, but I still have this gut feeling when I encounter a fellow programmer with the general put-together-ness of someone in the C-suite.

What makes it worse is that I've had this gut feeling validated several times in the past. I once worked with a very cover-of-GQ programmer who, after ten+ years in the industry, would struggle with FizzBuzz-esque problems.
