Here's an example:

> "More intelligent people get higher level jobs (and better employment (and higher salary) may lead to higher self-esteem, and encourage personal control beliefs."

This plays into society's implicit assumption that beliefs are subjective, and that objective truths cannot be known for certain. It's taking advantage of something that most people think, but don't realize they think, and therefore don't realize is an invalid assumption to make.

This article is suggesting that non-religious people, being more intelligent, are probably more correct in their beliefs about religion than religious people.

But, assuming that orthodox Christianity is correct[1], we know that the opposite is actually true: Christians are more correct in their beliefs about religion than non-religious people.

So the article suggests causation where there's only correlation.
