As a humble observer, it seems when ''works" is connected to prediction in astrology all manner of entanglement ensues.
My personal definition of astrology working more broadly asks the question: Can I prove astrology works to reflect life meaningfully? Well, yes I can, you and I and many are proof of that. Are personal subjectivity and individual opinion factors in what we humans find meaningful? Well, yes, I think they are, as with any philosophy or belief in life. Thus, can I prove to skeptics that astrology works? Very doubtful.
Jamie, I couldn't help noticing that you are an astrology practitioner - with 5 planets in discerning Virgo in the meaningful 9th House - who is currently involved in particular debate, as you say. Astrologically, this seems an apt reflection of mindful T Mercury, now in Virgo and contacting this significant area in your chart. Also seems like a perfect personal opportunity to observe the effects of Mercury Retrograde, coming later this week.
Best ahead with astrology.
