Rationale and Hypotheses: Police manuals seem to indicate that more experienced detectives are better able to detect deception than inexperienced detectives. In this study, we evaluated this claim with our sample of 1,052 police officers representing 256 police stations across England. First, we tested whether officers did better detecting lies for real-life criminals accused of crimes versus everyday people (students, business owners, and married individuals). We hypothesized that police officers with more experience would be able to detect deception amongst criminals accused of crimes with accuracy rates better than could be expected by chance alone.

None of the participants in this study specialized in lie detection. This study did not train the officers on how to detect lies.

Materials: Participants were asked to distinguish truths from lies in a variety of different situations by attending to any cues that they believed were indicative of deceptive behavior. Specifically, the participants saw 50 video clips of 50 different individuals (23 women and 27 men). 15 of the clips included suspects accused of crimes, like rape, murder, arson, and theft. 11 of the clips consisted of married individuals. 14 clips showed undergraduate and graduate students. The remaining 10 clips consisted of business owners. The individuals in the clips were all different, thus no one individual showed up more than once. The individuals in the video clips were asked to answer questions and were given instruction ahead of time that they could either lie or tell the truth. Only clips where the researcher knew ahead of time were lies or truths were shown to participants. Individuals in the video clips were asked to answer a variety of different questions.
