Summary The Behaviour Analysis Interview (BAI) is an interview protocol developed by John E. Reid and Associates to generate different reactions in guilty and innocent suspects. Even though research has questioned the usefulness of the BAI protocol (Vrij et al., 2006), many law enforcement officials are trained in the BAI every year. Two studies were conducted to examine whether the BAI recommendations are in line with lay participants' beliefs about the correlates of guilt or innocence. In Study 1, the participants read the transcriptions of two BAIs and had to indicate which one corresponded to the guilty suspect. Virtually all the participants who were familiar with the BAI protocol were successful in this task; however, more naïve participants (69%) than expected by chance were also able to identify the guilty interview. In Study 2, a questionnaire was designed to examine whether those behaviours that the BAI proponents maintain are guilt indicators were judged by lay participants as more indicative of guilt than those behaviours that the BAI proponents maintain that are indicators of innocence. The results strongly supported this prediction. Not only are the BAI recommendations inaccurate, but they are also in line with what people already believe. Apparently, little new can be learned by attending training seminars on the BAI. Law enforcement personnel should be taught interview protocols grounded on sound science instead of unsupported common‐sense beliefs. Copyright © 2010 John Wiley & Sons, Ltd.
