Three measures related to motivation to perform a rating task accurate
ly were obtained from 49 students, who also performed goal-attribute r
atings. Less motivated students surpassed more motivated ones on sever
al indices of rating bias. Previous evidence for differential relation
ships among goal attributes was clearly replicated only with the ratin
gs of more motivated subjects. These findings suggest that many respon
dents may strive for ''satisfactory'' rather than optimal goal ratings
(''satisficing''), that this tendency is a strong potential source of
error with such data, but that individual differences related to sati
sficing may be used to examine such effects and partially bracket them
out. It is suggested that measures of subjects' motivation or other r
elated personality characteristics be routinely gathered when multiple
ratings from subjects are required.
