研究表明，对不确定性证据的偏见（BADE）可能有助于在面对压倒性的证据时保持错觉。这项研究的大部分都采用了伍德沃德和同事的BADE任务。研究人员目前使用不同的评分方法，其中许多方法都有明显的缺点，因此很难比较BADE研究的结果。BADE研究的持续发展需要一种具有更有利的心理测量特性的评分方法，该方法被研究人员更一致地使用。在这里，我们采取数据驱动，但理论知情的方法来开发一种新的方法来评分的BADE任务。这种新的评分程序比以前的BADE指标更简约，但捕获了绝大多数与妄想有关的预测方差。因此，这种新方法可能能够激发BADE研究人员的共识使用。如果是这样的话，它可以大大增加比较未来BADE研究的容易性。
Research suggests that bias against disconfirmatory evidence (BADE) may help maintain delusions in the face of overwhelming evidence against them. Much of this research has employed Woodward and colleagues' BADE task. Different methods of scoring this task, many of which have significant drawbacks, are currently used by researchers, making it difficult to compare results across studies of BADE. Continued advancement of BADE research demands a scoring method with more favorable psychometric properties that is used more consistently by researchers. Here, we take a data-driven but theory-informed approach to the development of a new method for scoring the BADE task. This new scoring procedure is more parsimonious than previous metrics of BADE but captures the vast majority of their predictive variance in relation to delusions. This new method may therefore be capable of inspiring consensus use among BADE researchers. If so, it could significantly increase the ease of comparing future studies of BADE.
