The objective of this research is to identify which kinds of social accounts can be more effective to mitigate distrust when the different violations emerge.Mainly there are two kinds of violations: integrity-based violation and competence-based violation.Sellers can make responses (denial and apology) to the violations when the violations emerge,trying to remove distrust of the observers.We also test the mechanism of how social accounts can repair distrust.According to the casual attribution theory,we identify one mediators: stability.Through the literature review,we propose that denial will be more effective to reduce stability perception than apology when the violation is integrity-based.In contrast,apology will be more effective to reduce stability perception than denial when the violation is competence-based.We also hypothesize that stability have positive affect on distrust.
