[EN]Deception detection research has shown that police officers are less truth-biased and make their veracity
judgments with greater confidence than do nonofficers. Here we examined nonofficers, novice officers,
and experienced officers’ response bias, confidence, and generalized communicative suspicion. In
Experiment 1, novice officers aligned with nonofficers in terms of both generalized communicative
suspicion scores and confidence, with both these groups scoring lower than experienced officers.
Generalized communicative suspicion scores and veracity judgments were not significantly related for
either sample. However, novice officers aligned with experienced officers in terms of judgments: both
police groups were lie-biased, whereas nonofficers were truth-biased. These findings suggest that unlike
experienced officers, who have embraced the police culture to a greater degree, novice officers are not
dispositionally suspicious (generalized communicative suspicion); however, they are able to mirror the
prototypical police behavior (deception judgments) in police-related contexts. Experiment 2 supported
these notions.
