I know lots of ppl with years of sobriety through AA so I would say it does work for some. It existing as a choice free of charge around the world for ppl suffering is a good thing.

I know lots of people who haven't been attacked by bears since they bought a bear protection talisman so I would say that they work for some.

Yeah except those people don't intrinsically enjoy being attacked by bears despite that it will kill them, and the attacking bears aren't featured as a prominent aspect of the social fabric visible in everyday life, on nearly every corner, tv ad, social event, and otherwise.
