Last year Gregory Paul updated a study
on the value of living in a religious society. He clearly shows that the more religious a society is, the worse life is for the society. He collected data from all over the world, so it's not just a US study. There were criticisms in his 2005 report on it so the second one really was designed to silence the critics.
If you were to listen to Evangelicals and Baptists, you would expect that the more you worship God, fight abortion, stand against gay marriage and the like, the better off you'll be. You'll be Blessed!
Someone assembled a selective graph that has some good info on it for addressing what you get as a side order with your religiosity in the US. Greater divorce rates. Higher Murder Rates. Higher Theft rates. Greater poverty. But on the lower side you do have IQ, and.... and... Health and Contentment, so at least you have that going for you.
Kudos to the person who put this graph together. It really does show the benefits of conservatism and religion.
