Personality Differences between Pro- and Antivivisectionists

Abstract We examined the possibility that opinions on the animal rights debate reflect differences in personality. Our survey of 1055 college students compared scores on the Myers-Briggs Type Inventory and other personality measures with scores on the Animal Research Survey. We found people supportive of animal experimentation more likely to be male, masculine, conservative and less empathic than those opposed to it. Animal rights advocates were more likely to support vegetarianism and to be more ecologically concerned. They also indicated less faith in science. Students likely to encounter animal experimentation in their studies (psychology, biology majors) tended to oppose animal experimentation more than others. Intuitive and feeling types were more opposed to animal experimentation than were sensate and thinking types. Extraverted-sensate and extraverted-thinking types were more likely to favor animal experimentation than were extraverted-intuitive and extraverted-feeling types. Implications of these results are discussed.
