Despite the evidence on Pluto, there's no way that I, or anyone else is going to wean the psychologists off their addiction. And I suppose from their mindset, Pluto does have meaning.
My issue is that there is no rational reason why Pluto should be considered important. but then psychologists and psychaitrists are often concerned with the irrational LOL,
Why do people report dreadful things from Pluto transits? I suspect that it's another psychological phemomenon, the power of suggestion. If you're told that Pluto will give you a hard time for the next six months, then anything that goes wrong has an obvious answer - IT'S PLUTO. No need to look elsewhere in the natal chart, or in return charts. So it also leads to careless Astrology. Not looking and checking all possible Astrological causes.
At the time of Pluto's discovery, Astronomers were searching for Planet X, and Pluto was discovered very near where Percival Lowell predicted Planet X would be. So it was quickly accepted as a planet. However as more was learned about it it became abundantly clear that it wasn't Planet X and did not follow the predicted orbit.
So Pluto created obfuscation and misunderstanding - sounds like Neptune doesn't it?
