But they're generally not actually beliefs, in the sense that they wouldn't stake any substantial value on them. They are "performative" beliefs that are indicative of belonging to a certain subculture. What's interesting is when those performative beliefs collide with factual consequences (eg, COVID deniers dying of COVID). Nobody has died of "belief" in astrology as far as I know. I imagine most astrology fans would cop out if there were real consequences involved.
