Does the "how" actually matter ? Something does not become real because we can explain it, explanation follows establishment of the real. For decades the western medical profession has dismissed acupuncture as voodoo hedge-witch nonsense on the basis that they don't know how it works. Unfortunately the repeatable & measurable nature of the effects has kinda confounded western notions of the superiority of our understanding of the body. It is only recently that improved and more subtle research has begun to unravel how acupuncture might be understood.

Equally, the fact that there is, as yet, no western scientific theory that might encompass astrology doesn't undermine that, to those who have studied it, the ability to discern useful understanding of individual's personalities is real and discernable. I don't see fit to dismiss something simply because I don't understand how it can work (transistors must be a bugger for people of that persuasion) or because of the lack of credibility of its major proponents.
