Research on moral judgment has been dominated by rationalist models, in whi
ch moral judgment is thought to be caused by moral reasoning. The author gi
ves 4 reasons for considering the hypothesis that moral reasoning does not
cause moral judgment; rather, moral reasoning is usually a post hoc constru
ction, generated after a judgment has been reached. The social intuitionist
model is presented as an alternative to rationalist models. The model is a
social model in that it deemphasizes the private reasoning done by individ
uals and emphasizes instead the importance of social and cultural influence
s. The model is an intuitionist model in that it states that moral judgment
is generally the result of quick, automatic evaluations (intuitions). The
model is more consistent than rationalist models with recent findings in so
cial, cultural, evolutionary, and biological psychology, as well as in anth
ropology and primatology.
