10 reasons Americans go to church -- and 9 reasons they don't

(CNN)If American religion were traded at a stock exchange, your broker might be advising you to sell. The trend lines don't look great and haven't for quite some time.

Social scientists and religious leaders have lots of theories about the long, slow slide, blaming it on everything from the internet to the politicization of conservative Christianity.

Some of their answers are unsurprising. Americans who don't believe in religion don't often attend church. Because duh.
