Sammanfattning (abstract):
This study sought to evaluate the efficacy of the strategies employed by the iconic WWII interrogator Hanns Scharff. The objective was to identify science-based strategies for effectively eliciting intelligence from human sources. In Experiment 1 (N = 119) we made the interviewer-source interaction more realistic (compared to previous research), and in Experiment 2 (N = 200) we mapped the comparative efficacy over different types of sources. In both experiments the participants were given information about a planned terrorist attack, asked to take on the role of ‘sources’, and instructed to strike a balance between not revealing too much or too little information in a subsequent interview. They were then interviewed with either the Scharff-technique (conceptualized as four different tactics) or the Direct Approach (open and direct questions). The overall result showed that the Scharff-technique resulted in significantly more new, and more precise, information than the Direct Approach. The sources interviewed with the Scharff-technique had a comparatively more difficult time reading the interviewer’s information objectives. Finally, the sources interviewed with the Scharff-technique significantly underestimated, whereas the sources in the Direct Approach generally overestimated, how much new information they revealed. The study marks the Scharff-technique as a promising human intelligence gathering technique.
