Firstly: astrology does not work out people's personalities.
The personality is a combination of genes, circumstance and astrological sign. Different for each person, but I'd say about 25%, 50%, 25% spread respectively.
Secondly: the 'tests' that have been done to 'disprove' astrology thought that astrology was about predicting someone's entire personality. They also were chock full of questions that gave both the upside and the downside of a trait (surreptitiously).
Thirdly: astrology often has sources of hocus pocus and sources of fact. I don't believe you can tell the future for anyone or anything with astrology. Some things I'll accept because I have enough evidence for them, some things I won't- there are charlatans everywhere, but that doesn't make the whole thing hocus pocus
Fourthly: astrology is not anything like religious belief. It means barely ANYTHING to most people who are interested in it, like me. It's not some special subscription service for lame ass cosplay mystics and pseudo druids. It's not useful for much other than understanding SOME personality issues with yourself and with your friends.
I only believe in any astrological concept if I have 100% evidence for it.
Fifthly: carrying on, astrology is often useful for working out where your true leanings are, when they have been covered up by circumstance (or nurture). For example, a middle of the month cancer should be quite naturally loving and caring towards his closest friends and family. However if he is guarded with everyone, and refuses to cry in front of people, and barely ever connects, it's because he will have been either forced to do it or because he has grown to do it. It will be an unhealthy and dissatisfying issue for him all his life until he accepts that he is someone who really wants to open up to his nearest and dearest.
It's therefore useful for helping understand your family members, and most importantly for helping to understand your own problems.
Sixthly: On this forum people might bring up a heated argument between Jibba and I in which I made a fool of myself in several ways, not least because I gloated about how he was obviously one star sign, when he turned out not to. The simple fact of that matter is that you can't know much about someone's star sign from a few interactions with them, and peoples' internet (guarded and often bravado-laden) personalities are a damn sight different from their true ones. That's just to cover anyone using that as a pathetic excuse to disengage with what I've put.
Seventhly: sun signs (the 12 signs of the zodiac) are not clear cut. There aren't just 12 different astrological leanings. It's like colours...they bleed into each other. There's an infinite number...but general themes will stay and that's what's important.
Eighthly: Something I find really irritating is that people aren't willing to accept the murkiness of astrology. Because it does not give a person's full personality (as it's different because of genes and circumstance) it can never really give a clean cut, on-demand, perfect analysis of someone. People are very unwilling to be open-minded about things like this. They think that because it cannot be put into one sentence, it is an automatically invalid concept. You get a lot of hostility when explaining like this to most pig-headed people.
Ninthly: astrology is always an easier concept to grasp for people who analyse...as well as people who like to put everything into a logical box. If you are one of those sorts of people, you will probably have already made assessments on everyone around you, and astrology will either fit or conflict...and you can test the waters so to speak. If you are completely unaware of peoples' personalities around you, and you don't pick up on any patterns of behaviour, you will find it almost impossible to understand how it works.
And finally...tenthly...astrology is a LOT easier to work out with kids than with adults. Especially men between 16-25. They take such control of their outward personality towards people, and they repress so much of their nature, often they will strike a complete discord with their sun sign in several key areas. That doesn't disprove astrology though, it just shows they are repressed as fuck. You see it all the time really, especially in teenagers. Repression is a really big and obvious thing if you just keep your eyes out for it.
I just felt like putting that out there. Now comes the shitstorm indubitably...
