This research demonstrates that two- versus one-sided counterattitudinal messages can encourage people with a strong moral basis for their attitudes to be more open to contrary positions. Studies 1A/B demonstrated that the interaction between moral basis and message sidedness was present not just for a controversial issue with balanced views in society but also for a topic with a majority opinion. In Study 2, the relative effectiveness of two- over one-sided messages for people with a moral attitude basis was shown to occur only when the two-sided message respectfully acknowledged the recipient's side. In Study 3, the effect was replicated in a preregistered experiment. Furthermore, moral bases provided unique predictive power beyond alternative attitude strength indicators. Across all studies, perceived appreciation of the speaker acknowledging the recipient's view mediated the impact of the independent variables on openness.
这项研究表明，与单边相反观点的信息相比，双边相反观点的信息可以鼓励那些对自己的观点有强烈道德基础的人更愿意接受相反的观点。研究 1A/B 表明，道德基础和信息单边性之间的相互作用不仅存在于社会上观点平衡的争议问题上，也存在于多数派观点的话题上。在研究 2 中，只有当双边信息尊重地承认收件人的观点时，双边信息相对于单边信息对具有道德态度基础的人的相对有效性才会显现出来。在研究 3 中，该实验在预先注册的实验中得到了复制。此外，道德基础除了替代态度强度指标外，还提供了独特的预测能力。在所有研究中，感知到演讲者对收件人观点的赞赏程度，调节了自变量对开放性的影响。
