Sorry, that AA “study” is bullshit.
I don’t care who published it. It’s wrong. And it could be the reason someone doesn’t try to get help.
I’ll start by saying this: Alcoholics Anonymous is the sole reason I am not dead. So I’m biased as hell.
It seems every few years a new study comes out saying how Alcoholics Anonymous isn’t effective, or is a cult, or that something else has come along that is better. I’m not going to link to them, but they’re easily found online. I’m only here to share my own experience, since that’s the only thing that I can speak on with any authority.
