I'm at a loss where to start. Accepting that no scientific study has ever found any basis in astrology, you claim that this is because scientific method is somehow 'wrong' and incapable of dealing with people.
Science is very good at dealing with people. it uses lots of boring statistics and number crunching, but it comes up with results. Psychology is a science. Companies and instutions all over the world use tests like the Myers Briggs to assess personnel. It is based on boring science, and it's about people.
I know of no reputable company that uses astrology as a means of staff assessment or recruitment. Doesn't that in itself tell you something?
