[EN]The Behaviour Analysis Interview (BAI) is an interview protocol designed to generate different
reactions in guilty and innocent suspects. Masip et al. (in press) found that students had the same
views about the guilt or innocence indicators of the BAI as the BAI proponents. This suggests that
training in the BAI may only reinforce the trainees’ pre-existing beliefs. However, the typical BAI
trainees are not students, but law enforcement personnel. In this study, Masip et al.’s questionnaire
was administered to novice and experienced officers. Results revealed that the officers share the
BAI proponents’ assumptions to the same extent as Masip et al.’s student sample. Averaging
across all three samples, support was found for the prediction that the BAI notions are just
common sense for all of the BAI questions but one. A marginal trend emerged for veteran officers
with interviewing experience to assign more guilt to the suspects’ reactions than their peers
without such experience.
