The present study investigated guilty mock‐suspects' counter‐interrogation tactics with respect to the disclosure of possibly self‐incriminating information, specifically, to what extent the disclosure of this information was moderated by (1) the suspects' criminal experience (naïve versus experienced) and (2) the degree of suspicion directed towards the suspects (low versus high). We found that experienced (versus naïve) suspects volunteered less self‐incriminating information in an initial free recall phase. In a similar vein, when asked crime‐specific questions, naïve (versus experienced) suspects admitted having committed more actions fitting with the crime under investigation. Furthermore, experienced suspects' willingness to report information was not affected by the degree of suspicion, whereas naïve suspects in a high‐suspicion (versus low‐suspicion) condition were more willing to report information. The results were discussed in the light of the psychology of guilt, the Strategic Use of Evidence technique for detecting deception, and the (over)use of naïve suspects as mock‐suspects in psycho‐legal research.
