Explaining own and others' behavior in a controversial issue: animal experimentation

The authors investigated how 2 groups with different attitudes toward animal experimentation-researchers who conducted animal experiments and members of animal welfare organizations who protested against animal experiments--made attributions for the behavior of the opposing group. The 2 groups showed an actor--observer effect, mentioning more internal causes for the opponents' behavior and more external causes for their own behavior. Both groups were able to take the other's perspective, resulting in a reversed actor-observer effect. The less involved participants followed the pattern of ratings of the group whose attitudes corresponded to their own. In particular, the participants with a negative attitude toward animal experimentation rated researchers' behavior as more internally caused than did those with a positive attitude. The results illustrated how the participants formed and defended attitudes in a social context.
