Why Alcoholics Anonymous Works

David Brooks nails it on the head:

In a culture that generally celebrates empowerment and self-esteem, A.A. begins with disempowerment. The goal is to get people to gain control over their lives, but it all begins with an act of surrender and an admission of weakness.

In a culture that thinks of itself as individualistic, A.A. relies on fellowship. The general idea is that people aren’t really captains of their own ship. Successful members become deeply intertwined with one another — learning, sharing, suffering and mentoring one another. Individual repair is a social effort

Don't deal with the symptom, deal with the person:

In a world in which gurus try to carefully design and impose their ideas, Wilson surrendered control. He wrote down the famous steps and foundations, but A.A. allows each local group to form, adapt and innovate. There is less quality control. Some groups and leaders are great; some are terrible. But it also means that A.A. is decentralized, innovative and dynamic.

Alcoholics have a specific problem: they drink too much. But instead of addressing that problem with the psychic equivalent of a precision-guidance missile, Wilson set out to change people’s whole identities. He studied William James’s “The Varieties of Religious Experience.” He sought to arouse people’s spiritual aspirations rather than just appealing to rational cost-benefit analysis. His group would help people achieve broad spiritual awakenings, and abstinence from alcohol would be a byproduct of that larger salvation.

This is also useful outside of the specific problem of alcoholism.
