A study that showed that there is a connection between starsigns and peoples personalities.
I've heard of this, but I haven't found it.

Have you tried using google? If so, and you still haven't found it, I'd try using the ATS Search feature. I'll take a look around for you, because it seems like I remember reading something, somewhere, about this.

You may me astrology.. Which basically says that there is a corrolation between the dates people were born on (which connects to the stars) and their personalities. Usually, you see horoscopes in newspapers and magazine, but they tend to make a mockery of the subject...

Through my experience there are alot of connections between personalities and dates of birth, but like most of the Paranormal.. Nothing is set in stone..
