Sammanfattning (abstract):
In previous research the Scharff technique has consistently outperformed the Direct Approach for gathering intelligence from human sources (Granhag, Kleinman, & Oleszkiewicz, 2016). However, little is known about the extent to which the same technique can be taught to practitioners in the field, and how the performance of Scharff trained interviewers compare against interviewers using their conventional approaches and tactics. For the current study we examined professional handlers from the Norwegian Police (N = 64), all experienced in interacting with informants. Half received training in the Scharff technique and their performance was then compared against handlers receiving no Scharff training (and free to use the approaches and tactics they saw fit). All handlers received the same case-file describing a source holding some information about a future terrorist attack, and all were given the same interview objectives. Police trainees took on the role of semi-cooperative sources and were given incomplete information about the attack. The results showed that the trained handlers adhered to the Scharff training as they (a) aimed to establish the illusion of ‘knowing-it-all’, (b) posed claims to collect information and (c) asked very few (if any) explicit questions. Importantly, the untrained interviewers did not use these tactics, instead they prioritized to try to evoke the sources’ motivation to reveal information. As predicted, Scharff trained interviewers collected comparatively more new information, and were perceived to be less eager to gather information. These findings capture the essence of the Scharff technique; it is subtle and effective.
