Rub the Genie Lamp

So I took this chain email "personality test." You know, like, describe the following animals and colors, and then it turns out that's how you feel about yourself and premarital sex. So of course the results are ridiculous, but I start to believe them. Well... maybe my life is "salty," and maybe my "twin soul" is... me. That's pretty deep, y'know? And then I'm stuck passing it along to 26 people so that I don't lose the wish I made at the beginning. (I'm pretty savvy. I wished for something lame, knowing that to get my wish I'd have to extend the email chain. Wishes never come free. You gotta rub the genie lamp.) Why do we tend to believe shit like that? If someone just up and told me, "You're life is rather salty, and I believe you are your twin soul," I'd be like, "You're a nice homeless man. Here's a dollar." So why do I believe it because it came in the form of a ridiculous Q-and-A session supposedly endorsed by the Dalai Lama?
