Here is the link to the story on CNN.
Like that bumper-sticker that says "Don't pray in my school, and I won't think in your church." :)
I am assuming that less educated people are also more likely to work a schedule which would hinder church attendence. The higher your education level the more picky you can be about where and when you work. Less educated people are more likely to work third shift and/or weekends. I wonder if this has anything to do with the results.
