NOEL KING, HOST:
This is one of those debates that has been going on for a long time. Does being part of an organized religion improve your mental health? The host of NPR's Hidden Brain, Shankar Vedantam, joins us to share some new research on this subject. Hey, Shankar.
SHANKAR VEDANTAM, BYLINE: Hey, Noel.
KING: So I feel like I've read reports before that say if you're religious, it does benefit your mental health in some ways.
