There have, of course, been hundredds of studies of astrology.
Absolutely none have found anything in it.
In order to explain the lack of any objective evidence in Astrology’s favour, some astrologers resorted to the paranormal.
They believe that astrologers can only arrive at the correct interpretation of a chart by using their higher intuition or by tuning in with the cosmic order!!!
wow
Much of astrology is untestable and escapes scientific scrutiny by confining itself to statements that can not be falsified. So the line goes that a horoscope can only provide information about our inner life, basic nature, true reality, hidden potential, deepest aspirations, unconscious fears and motives, forgotten trauma's and possibilities for future development.
Astrology "gives insight into the meaning and quality of our subjective experiences by locating them within a cosmic frame of reference. It tells us why we are the way we are, it can clarify our problems and help us to find solutions - but it can not predict our behaviour".
So nothing can prove it wrong.
Then there is the other "progressive" school of astrologers who regard astrology as a counselling skill. To them the horoscope is only a therapeutic tool and not a source of reliable information.
How irrational is that?
