A meta-analysis assessed whether exposure to information is guided by defense or accuracy motives. The studies examined information preferences in relation to attitudes, beliefs, and behaviors in situations that provided choices between congenial information, which supported participants' pre-existing attitudes, beliefs, or behaviors, and uncongenial information, which challenged these tendencies. Analyses indicated a moderate preference for congenial over uncongenial information (d=0.36). As predicted, this congeniality bias was moderated by variables that affect the strength of participants' defense motivation and accuracy motivation. In support of the importance of defense motivation, the congeniality bias was weaker when participants' attitudes, beliefs, or behaviors were supported prior to information selection; when participants' attitudes, beliefs, or behaviors were not relevant to their values or not held with conviction; when the available information was low in quality; when participants' closed-mindedness was low; and when their confidence in the attitude, belief, or behavior was high. In support of the importance of accuracy motivation, an uncongeniality bias emerged when uncongenial information was relevant to accomplishing a current goal.
一项荟萃分析评估了信息接触是否受防御动机或准确性动机的引导。这些研究考察了在提供选择的情境中,与态度、信念和行为相关的信息偏好,这些情境包括提供支持参与者先前存在的态度、信念或行为的相宜信息,以及挑战这些倾向的不相宜信息。分析表明,相较于不相宜信息,对相宜信息存在中度偏好(d=0.36)。正如预测的那样,这种相宜性偏差受到影响参与者防御动机和准确性动机强度的变量的调节。为支持防御动机的重要性,当参与者的态度、信念或行为在信息选择之前就得到支持时;当参与者的态度、信念或行为与其价值观无关或并非坚定持有时;当可得信息质量较低时;当参与者的思想封闭程度较低时;以及当他们对态度、信念或行为的信心较高时,相宜性偏差较弱。为支持准确性动机的重要性,当不相宜信息与实现当前目标相关时,会出现不相宜性偏差。
