Research shows that police officers are no more accurate than non‐officers in discerning between truthful and deceptive statements, but more biased than non‐officers to judge statements as deceptive. This was labeled by Meissner and Kassin (2002) as the investigator bias effect. A likely explanation could be that, since officers are normally involved in situations where questioning the truthfulness of the interviewee is essential, they could develop a generalized communicative suspicion (GCS). Levine and McCornack's (1991) GCS scale was adapted to the Spanish context and used to compare the GCS ratings of 152 undergraduates, 88 experienced officers, and 89 police recruits. Experienced officers’ GCS scores were significantly higher than those of the other groups, which did not differ from each other. This suggests that socialization within the police force increases the officers’ suspicion, leading them to make deceptiveness judgments.
