According to a recent article on PawNation.com, Dog lovers are more outgoing, while Cat lovers are smarter. After surveying 600 college students, researchers concluded what most of us already knew: Dog people and cat people are very different. "It makes sense that a dog person is going to be more lively, because they're going to want to be out there, outside, talking to people, bringing their dog," said study researcher Denise Guastello, an associate professor of psychology at Carroll University in Waukesha, Wisc., who presented the findings at the annual Association for Psychological Science meeting. The majority of the students surveyed identified as dog people, according to Live Science: about 60 percent, compared with 11 percent who said they were cat people. A number who said they like both or neither. The dog lovers reported that companionship was the most important attribute in a pet, whereas cat lovers cited affection.
