Although it is generally believed that the evaluation of opposing information leads to changes
in existing perspectives and decisions, research has found that confirmatory bias in the evaluation of
opposing reasons in moral judgments leads to subjects’ refusal to change their original moral decisions.
This study investigates whether interpersonal relationship influence individuals’ evaluation of moral
reasons and thus change their degree of certainty about their original decisions based on the “pattern of
difference sequence” theory of interpersonal relationship. The results showed that the subjects’ evaluation
of moral reasons varied according to the interpersonal relationships of the moral subjects, but the
interpersonal relationships did not affect the degree of certainty of the original moral perspectives. The
current study further explores the influence of interpersonal relationship on moral judgments and further
verifies the existence of a “pattern of difference sequence” in Chinese people’s moral judgments.
