The discounting principle in attribution theory was considered a well-
established phenomenon until recently, when both the empirical and the
oretical basis for discounting have been questioned. Many instances of
strong discounting have used measures that constrain explanations, su
ch as a forced-choice and bipolar measures. Two studies were performed
simulating Thibaut and Rieckens study of attributions for target pers
ons' compliance to a request, which used a forced-choice measure. In t
he present studies, a range of measures were used. Responses of two sa
mples of Oxford students and one sample of Oxford teachers indicate th
at multiple causation was perceived and subjects did not greatly disco
unt either of two relevant causes, but there was nonetheless a compens
atory relation between the causes. The results also indicate that the
attributions were affected by the social categories of the target pers
on and the subjects.
