INTP :: 4w5-5w4-??? sx/sp :: Virgo Sun, Scorpio Moon/Rising
I find a big correlation in that they're all nothing more than a system.
I've been heavily interested in astrology for about a year, so I know quite a bit (but not too much). I agree that the use of astrology as a divination system and a way to "predict the future" is mostly bs. Plus those newspaper horoscopes that people believe also tend to give it a bad name.
I think that astrology (if used for such a purpose) is not so much different from the MBTI or the Enneagram. It's just another personality system. It says that when you were born, the planets left an energy imprint on you. It's kind of like a picture: a picture of the sky was taken at your birth, and that picture is the map of your personality.
I know most people who I talk to who disbelieve in astrology talk about how their sun sign doesn't fit them at all and how their horoscope never came true. That's because those horoscopes are bull. And your sun sign is truly not your entire personality. I myself used to think, I don't act entirely like a Virgo, so there's no way this can be true. But I looked into it, and I learned about the Moon Signs, and the Rising Signs, and other aspects of who you are, and everything made so much more sense after that.
So no, I don't believe it works in the whole predicting the future/divination sense, but I do think it correlates with MBTI and Enneagram in that it's just another personality system. Just another tool that can be used to help better understand yourself and those around you.
