Behavioural observation programmes are becoming increasingly popular at transportation hubs, sporting events, and other large crowd gatherings. Premise of these programmes is that malicious intention can be accurately deduced from observable behaviour. In a recent article published in this journal, Wijn et al. (2017, Legal and Criminological Psychology, 22, 378–399.) conclude that environmental cues improve the correct detection of participants with malicious intent. This conclusion can and will be interpreted as support for behavioural observation programmes. In this comment, we argue that Wijn and colleagues draw a fundamentally wrong conclusion from their data. What their data show is that malicious intentions could not be detected in any of the conditions. Their findings can therefore not be conceptualized as evidence for behavioural observation programmes. Rather, they add to the growing critique voiced towards such programmes.

未能从敌人那里告诉朋友：对Wijn​​等人的评论。（2017）

行为观察计划在交通枢纽，体育赛事和其他大型人群聚会中越来越受欢迎。这些程序的前提是可以从可观察的行为中准确推断出恶意意图。Wijn等人在该杂志最近发表的一篇文章中。（2017，法律与犯罪心理学，22（378-399。）得出结论，环境提示可以提高对恶意目的参与者的正确检测。该结论可以并且将被解释为对行为观察计划的支持。在这篇评论中，我们认为Wijn及其同事从他们的数据中得出了根本错误的结论。他们的数据表明，在任何情况下都无法检测到恶意意图。因此，他们的发现不能被概念化为行为观察计划的证据。相反，它们加剧了对此类计划的批评。
