"In a paper to be published later this year in the journal Anthrozoös, Sam Gosling finds that those who define themselves as "dog people" are more extraverted, more agreeable and more conscientious than self-described "cat people."
Fans of felines, on the other hand, are more neurotic but also more open than their canine-loving counterparts."
This doesn't surprise me at all, but then again I like dogs a lot more than cats. (T-shirt: "I like cats, I just can't eat one all by myself.")
There is the issue of causation vs. selection here. Does having a cat make you neurotic or do neurotic people buy cats? Also, what happens to people who have both a cat and a dog. Do they get the best of both? The worst of both?
For me being around cats predicts being very anti-social, but that's just because I'm in the bathroom blowing my nose and washing my face trying to undo an allergic reaction.
BTW, as I write this, Attila is jumping on me, loving on me--giving evidence for causation.
