Research has consistently shown people predominantly rely on undiagnostic nonverbal cues when detecting deceit, whereas verbal cues are more accurate. In three experiments, we investigated whether the simple instruction not to focus on nonverbal cues would make people focus more on diagnostic verbal cues and hence more accurate in detecting lies.…

Nahari, Vrij, and Fischer [(2014b), "Applied Cognitive Psychology," 28, 122-128] found that, when participants were forewarned that their statements would be checked for verifiable details, truth tellers gave much more verifiable details than liars. In this direct replication (n = 72), participants wrote a statement claiming they had…

The present experiment investigated to what extent providing participants with a model statement influences the ability of the verifiability approach to detect deception. Participants gave a true and false statement about a negative autobiographical event, with half of the participants receiving a detailed model statement just before giving their…

Scientific misinformation and disinformation, proliferating via the internet and social media, are now significant problems. Proposed solutions vary substantially. Here, I describe a set of prospective benchmarks--10 competencies--that seem essential for reorienting science education to address the challenge. They include, first, elements of…

The verifiability approach (VA) is a lie-detection tool that examines reported checkable details. Across two studies, we attempt to exploit liar's preferred strategy of repeating information by examining the effect of questioning adult interviewees before the VA. In Study 1, truth tellers (n = 34) and liars (n = 33) were randomly assigned to…

Detecting lies is crucial in numerous contexts, including situations in which individuals do not interact in their native language. Previous research suggests that individuals are perceived as less credible when they communicate in a nonnative compared with native language. The current study was the first to test this effect in truthful and…

In this study, we investigated whether people who hold more correct beliefs about verbal cues to deception are also better lie detectors. We investigated police officers and undergraduates' beliefs about (i) cues to deception via an open-ended question and (ii) 17 specific verbal cues, after which participants were asked to judge the truthfulness…

Verbal deception detection has gained momentum as a technique to tell truth-tellers from liars. At the same time, researchers' degrees of freedom make it hard to assess the robustness of effects. Replication research can help evaluate how reproducible an effect is. We present the first replication in verbal deception research whereby ferry…

Educational videos are becoming increasingly important for schools. More and more often, students consume videos on YouTube in order to carry out school tasks. At the same time, the digital world is increasingly influencing perceptions of history. The internet contains numerous examples of how history is instrumentalized. Counterfeiting and…
