I'm confused. There are a lot of things I might associate things like "behavioral economics" with, but New Age wouldn't have been what I'd have expected. Where do you get that from?
Actually, the proper definition (for the sake of understanding) is to treat this phenomenon as psychological therapy sessions. Based on my reading at the source, this group and the people involved, are engaged in a group therapy sessions. Now, one can bring association to religion, fairy tales, science, etc, but the essence stays the same. It is all about human beings trying to find meaning in their lives.
