Replicating findings reported in the experimental social psychological literature, this field study found that a negative bias prevailed in the appraisal of a set of lectures given by eight psychologists: the mean rating for the set as a whole was significantly smaller than the mean rating for the individual Iectures. This occurred despite the fact that about 50o/o of the subjects (N = 50) produced higher ratings for the set than the lectures and was explained by the existence of greater differences between sct and lecture ratings in the cases of negative bias (set < lectures) than in those of positive bias (set > lectures). Since significant differences between subsamples of positive and negative bias were observed in the ratlngs for the set but not in the ratings for the Iectures, it was concluded that the bias took place in the process of integrating information for rating the whole.
