There are various statistical links between atheism and high IQs. It doesn't mean that an atheist is intelligent, nor does it mean that if you are intelligent you are an atheist. All it means is that from current surveys, a high percentage of the intelligent people are atheists, and a lower percentage of lesser intelligent people are atheists.
There are multiple factors that are thought to be the cause. Primarily that people of high IQ are more likely to have open minds and think outside of any pre-learned dogma, whilst people of less IQ are more prone to believe things because they like them. Of course there are very stupid atheists out there, and there are very intelligent Christians (one of my friends is a fundamentalist and is very clever academically, and Ken Miller is a Roman Catholic evolutionary biologist, although he has thought outside of dogma a bit by denouncing the "literal" interpretation of genesis).
The studies merely show a trend amongst the populace.
