I doubt that. There's a lot of people going into programming because they think

a) IT is akin to playing computer games all day.

b) It's easy work in a climatized office with solid pay

c) The jobs are relatively secure and abundant.

I've seen many people go into IT that would much better have been employed elsewhere, so I think that we, as programmers are not more intelligent on average than the rest of the population. I might agree that people who enjoy programming have a knack for a certain type of intelligence and problem solving ability, but I don't think that programmers are limited to the group of people that enjoy programming.
