In their comment on our article on affective forecasting (Levine, Lench, Kaplan, & Safer, 2012), Wilson and Gilbert (2013) criticized the meta-analysis, proposed alternative explanations for the empirical studies, and concluded that the impact bias is alive and well. Our reply demonstrates that, irrespective of the exclusion of effects and selective recoding of effects recommended for the meta-analysis, the pattern of results remains the same: Study participants' forecasts are more accurate when they report their feelings about a focal event, or immediately after a focal event, than when they report their feelings in general after a delay. New analyses rule out individual differences and focalism as alternative explanations for the results of our empirical studies. These studies show that people can accurately predict the intensity of their feelings about events. People overestimate in predicting the impact of events on their emotional state in general, but clarifying the meaning of the forecasting question reduces the magnitude of this bias. We conclude that the impact bias, which encompasses overestimating the intensity of feelings about events and overestimating the intensity of feelings in general, is both dead and alive. The importance of predicting feelings about events for decision making and the reasons people predict some features of emotion more accurately than others are discussed.
在对我们关于情感预测的文章(Levine、Lench、Kaplan 和 Safer,2012)的评论中,Wilson 和 Gilbert(2013)批评了元分析,对实证研究提出了替代解释,并得出结论认为影响偏差仍然存在。我们的回复表明,无论元分析建议排除效应和选择性重新编码效应,结果模式仍然相同:当研究参与者报告他们对焦点事件的感受,或在焦点事件后立即报告时,他们的预测比延迟后报告一般感受时更准确。新的分析排除了个体差异和焦点主义作为我们实证研究结果的替代解释。这些研究表明,人们可以准确预测他们对事件的感受强度。人们在预测事件对其整体情绪状态的影响时高估了,但澄清预测问题的含义会降低这种偏差的幅度。我们得出结论,影响偏差,包括高估对事件的感受强度和高估对一般感受的强度,已经既死又活。讨论了预测事件对决策的影响的重要性,以及人们为什么比其他方面更准确地预测某些情绪特征的原因。
