When consumers use computers to help make purchase decisions, how do they attribute responsibility for the positive or negative outcomes of those decisions? The results suggest that, in general, attributions of responsibility reflect a self-serving bias: Consumers tend to blame computers for negative outcomes and tend to take personal credit for positive ones. However, the results also suggest that, when consumers have a history of intimate self-disclosure with a computer, this pattern of attribution is significantly mitigated: Consumers are more willing to credit the computer for positive outcomes, and are more willing to accept responsibility for negative outcomes. In addition, this research provides evidence that the causal relation between self-disclosure and attributions of responsibility is partially mediated by attraction.
