I am a Sagittarius. However I believe that for the most part astrology is the result of the Forer Effect. I don't believe this mitigates any meaning that people are able to derive from it though.
When we see an image in a piece of art that makes us feel a certain special way and provides meaning, no one would say that it's bunk because it's just paint. I see astrology the same way.
I think of it as a sort of cognitive pareidolia, where we recognize a thought as familiar and with significance and then fit into our regular paradigm, ascribing meaning where we feel useful.
