Why are religious people happier?

There’s a lot of evidence that religious people, for example, are happier in a sense of life satisfaction and positive emotion in the moment. But is it the Christian who really believes in Jesus and reads the Bible? Or is it the Christian who goes to church, goes to the spaghetti suppers, donates to charity, participates in the volunteer stuff? Turns out, to the extent that you can disentangle those two, it seems to not be our beliefs but our actions that are driving the fact that religious people are happier. That’s critical because what it tells us is, if you can get yourself to do it — to meditate, to volunteer, to engage with social connection — you will be happier. It’s just much easier if you have a cultural apparatus around you.
