Sammanfattning (abstract):
The present study examines non-coercive interview techniques aimed for eliciting intelligence from human sources. Two versions of the Scharff technique were compared against the direct approach (a combination of open-ended and specific questions). The Scharff conditions were conceptualised into four tactics and differed with respect to when the confirmation tactic was implemented: before or after an initial open-ended question. Participants (n = 93) took the role of a source in a phone interview and were instructed to strike a balance between not revealing too little or too much information. In general, the Scharff technique outperformed the direct approach on all important measures. The sources in the Scharff conditions revealed more new information, and found it more difficult to understand the interviewer's information objectives. Importantly, the sources interviewed by the Scharff technique underestimated how much new information they revealed, whereas the sources interviewed by the direct approach overestimated the amount of new information revealed. Although no clear order effects of the Scharff tactics were found, we introduce an alternative method for implementing the confirmation tactic.
