Morality judgement: test of an averaging model with differential weights.

Ratings of persons described by sets of moral and immoral actions were inconsistent with additive and averaging models of information integration. An averaging model with differential weights could not give a consistent account of the effects of both the number of items and the heterogeneity of the items in the set. Highly immoral deeds appear to have an overriding influence on the overall judgment: Having committed one bad deed, a person will be rated "bad," with his good deeds having little influence. Morality judgment may thus represent a truly configural process.
