Relevant anecdotal evidence: I have a cousin who was really in to astrology a few years ago: so obviously my sister and I insisted she partake in an experiment. We had her do three specific readings (not just with signs but with the mercury rising nonsense for which she needed exact birth-dates and birth locations): for me, my sister and my brother who wasn’t there. She read them to us without indicating who they belonged to and we tried to see if we could tell which ones referred to us. The second one she read was just shocking to hear. It described me perfectly. I was in awe for about 10 minutes until the experiment finished and I learned that the reading that described me perfectly belonged to my sister.
