Thanks Penny, maybe I'll have to accept that astrology might not be entirely caught into testability and probably not entirely into the practice of astrologers too. Although I believe in 'social artefacts' and 'hidden persuaders' as explained in Smit's website, I find that some tests are a bit questionable. For example, astrologers who can't determine the owners of their charts when these have been mixed. Could psychologers do this with the results of their psychology test forms? Same is with testing under pressure in a laboratory setting. My father's aunt was clairaudiant but I would doubt if she would have been able to perform at command. For a while I'll take a break from person astrology and occupy myself with weather astrology etc.
