The gathering of human intelligence (HUMINT) occurs
across the globe 24/7. In the wake of terrorist attacks in
New York, Madrid, and London, and the increased threat
of terror worldwide, the need for effective HUMINT tech-
niques is more critical than ever (Brandon, 2011; Loftus,
2011). Some of these interactions may require little in terms
of tactical reasoning, whereas other interactions may require
advanced strategic considerations and elaborate tactical
skills. In light of this it is rather remarkable that such little
research has been conducted on how such interactions are
conducted and the comparative effectiveness of different
HUMINT gathering techniques. This special issue will begin
to remedy this serious gap in the research literature.
While the general body of literature underpinning the eld
of legal psychology continues to show a steady expansion, it
remains silent with respect to techniques aimed at eliciting
human intelligence. The existing literatureincluding re-
search on memory-enhancing techniques (e.g. Fisher &
Geiselman, 1992), confessions (e.g. Lassiter & Meissner,
2010), and deception detection (e.g. Granhag & Strömwall,
2004; Vrij, 2008)address vital elements in the overall in-
telligence gathering process, but there is very little research
that informs on how intelligence interviews are conducted
today and how such interviews could be improved. Turning
to the literature on human intelligence, there are writings on
the recruitment of informants (e.g. Fitzgerald, 2007), ethics
and informants (e.g. Andrew, Aldrich, & Wark, 2009), and
analyzing intelligence (e.g. George & Bruce, 2008). But the
literature on intelligence interviewingis very slim. This is
noteworthy considering the prominent role of human intelli-
gence collection operations in historical terms, and even
more so given the renewed interest of intelligence collection
in the period following 9/11 (Brandon, 2011). Although
operational experiences have given rise to a wide array of
techniques and procedures within the HUMINT domain,
these methods have rarely been subjected to scienticevalu-
ation. On a more positive note, researchers and practitioners
from the intelligence eld have begun to acknowledge this
gap and advocate for a more comprehensive future research
agenda (e.g. Evans, Meissner, Brandon, Russano, & Kleinman,
2010; Loftus, 2011). We believe that the papers in this special
issue add positively to such an agenda.
The Special issue contains 12 papers, and we are proud to
have received contributions from North America, Europe and
Australia. A closer look at the papers reveal that they cover
(a) experienced interrogators(and analystsand interpreters)
views regarding their own practices (Redlich, Kelly, & Miller,
2014; Russano, Narchet, & Kleinman, 2014; Russano,
Narchet, Kleinman, & Meissner 2014), (b) empirical tests
and systematic eld observations of different interview
approaches and tactics promoting the elicitation of human
intelligence (Evans et al., 2014; Luke, Dawson, Hartwig, &
Granhag, 2014; Goodman-Delahunty, Martschuk, & Dhami,
2014; Oleszkiewicz, Granhag, & Kleinman, 2014; Shaw
et al., 2014; Vrij, Mann, Jundi, Hillman, & Hope, 2014), (c)
memory enhancing techniques to assist sources who are
willing to share information (Leins, Fisher, Pludwinski,
Rivard, & Robertson, 2014; Rivard, Fisher,Robertson, & Hirn
Mueller, 2014), and (d) an overview of current research on
techniques for interviewing to elicit information and assess
credibility (Vrij & Granhag, 2014).
We would like to thank all of the external reviewers who took
on their task in such a serious manneryour efforts pushed the
issue in the right direction. Finally, we would like to thank Mark
Fallon, Susan Brandon, and Majeed Khader for offering such
encouraging and insightful comments on the issue.

... Researchers have recently begun to develop and evaluate the efficacy of different approaches to human intelligence gathering, aiming to develop ethically justifiable interview strategies (e.g., Granhag, Vrij, & Meissner, 2014;Justice, Bhatt, Brandon, & Kleinman, 2010). This research has underscored the importance of creating an overall positive atmosphere in the interview room, rather than relying on a specific recipe or "quick fix" for establishing rapport (Alison, Alison, Noone, Elntib, & Christiansen, 2013;Evans et al., 2013;Kelly, Miller, Redlich, & Kleinman, 2013;Walsh & Bull, 2012). ...

Eliciting information from semicooperative sources presents a major challenge in investigative and intelligence settings. This research examines the role of the human need to belong in individuals' willingness to disclose critical information. We hypothesised that social exclusion would exert a threat to individuals' need to belong and self‐esteem, which would make them strive for social reconnection through sharing information with others. In two experiments (N = 150 and N = 135), social exclusion and inclusion were manipulated before participants were given the opportunity to disclose critical information in a semicooperative game setting (Study 1) or a mock intelligence interview (Study 2). Social exclusion did not influence information disclosure in any of the experiments. Instead, however, social inclusion unexpectedly increased information disclosure in the interview setting. We conclude that prior social experiences can influence the outcome of subsequent interviews, but the precise mechanisms underlying such influence are currently unknown.
... After 8 years of funded research, there is now a growing corpus of unclassified and peer-reviewed studies from the HIG found in over 120 published journal articles and book chapters produced by respected psychologists from the USA and abroad (including Australia, Great Britain, South Africa, Sweden, and parts of the Middle East). They can be explored individually and in literature reviews of leading academic journals (HIG Bibliography 2017), and principal parts are available in a special issue of Applied Cognitive Psychology (Granhag et al. 2014). ...

By executive order—later passed into law—President Obama closed legal loopholes used to justify torture by his predecessor. Less often discussed, his administration also instituted scientific research into the most effective interrogation techniques. This dual-track approach already demands the use of two different methods to properly discuss the policy, and in this article, a third is put forward for a fuller interdisciplinary view. That is to say, although there are notable shortcomings, scientific and legal developments will be explored to illuminate how he also clarified a moral stance for the nation. Put all together, this article will show that Obama indeed achieved laudable steps towards preventing the reintroduction of torture.
... The scope of investigative interview and interrogation research has recently expanded from focusing almost exclusively on law enforcement to include an exploration of human intelligence gathering in military contexts (e.g., see Granhag, Vrij, & Meissner, 2014). This recent expansion has included, among other topics, interrogators' perceptions of interrogations (Russano, Narchet, Kleinman, & Meissner, 2014), the influence of interrogation settings on Recent work by linguistics scholars has highlighted the influence interpreters can have on processes and outcomes in the legal system (see Berk-Seligson, 2011;Hale, 2007, Hale, 2010. ...

This study explored the performance of interpreters in military intelligence-gathering interrogations. We coded transcripts of 10 interrogations of one detainee at an overseas U.S. military detention facility. The same interrogator conducted each session with the assistance of two interpreters who participated in one session together and worked alone in the remaining sessions. We coded interpretations as accurate (gist) or one of three errors: omission, substitution, or addition. We report accuracy and error rates across interpreters, as well as differences in interpretation accuracy as a function of the direction of interpretation (English-toArabic or vice versa). Interpreters were largely accurate, conveying the gist of information in at least 82% of interpretation attempts. However, they made a variety of errors which differed depending upon the direction of interpretation. Interpreters generally refrained from assuming the role of interrogator and using tactics or rapport building techniques. Implications and future directions are discussed.
... However, the development during the last few years has been positive, and the number of studies within this new strand of research is now approaching a critical mass (e.g. Granhag, Vrij, & Meissner, 2014). ...

In past research, the Scharff technique has consistently outperformed different comparison techniques with respect to the elicitation of human intelligence. This study extends previous work by examining the efficacy of the Scharff technique applied to small cells of sources. The sources worked in triads (N = 180), and were given information about a planned terrorist attack. They were then interviewed individually with either the Scharff technique (conceptualised as five tactics) or the Direct Approach (open and direct questions). The two techniques resulted in an equal amount of new information. As predicted, the sources in the Scharff condition underestimated, whereas the sources in the Direct Approach condition overestimated, their own contribution of new information. Furthermore, the Scharff tactics resulted in the sources overestimating the amount of information revealed by their fellow group members, whereas this was not the case in the Direct Approach. The paper advances the knowledge on elicitation techniques on several accounts: with respect to the context (focusing on small cells of sources), measures of efficacy (introducing a new dependent measure) and tactics (introducing novel context-dependent tactics). The outcome of the study marks the Scharff technique as a promising technique for eliciting information in intelligence settings.
... To remedy the paucity of research on human intelligence gathering, Granhag, Vrij and Meissner (2014) edited a special issue of the journal Applied Cognitive Psychology. The issue covers several important research avenues such as experienced interviewers' views of their own practices (Russano, Narchet, Kleinman & Meissner, 2014), suspects' counter-interrogation strategies (Luke et al., 2014), field observations for establishing rapport (Goodman-Delahunty, Martschuk & Dhami, 2014) and memory enhancing techniques (Rivard, Fisher, Robertson & Hirn Mueller, 2014). ...
Thesis
Full-text available
This thesis is on how to elicit intelligence from human sources with the principal aim being to examine the efficacy of the tactics employed by the renowned WWII interrogator Hanns Scharff. A novel experimental set-up (as well as new dependent measures) was introduced to evaluate the efficacy of different human intelligence gathering techniques. Participants were given information about a planned terrorist attack, asked to take on the role of “sources”, and instructed to be semi-cooperative in a subsequent interview. In Study I (N = 60), interviews were conducted over the phone. The Scharff technique (conceptualized to include five tactics) was compared to the direct approach (a combination of open-ended and specific questions). The Scharff technique resulted in relatively more new information and led sources to underestimate how much new information they revealed. With the Direct Approach, sources overestimated how much new information they revealed. In Study II (N = 119), interacting parties met face-to-face and the sources were allowed to lie. Two versions of the Scharff technique were compared to the direct approach. The Scharff confirmation technique made use of claims that included the correct alternative while the Scharff disconfirmation/confirmation technique made use of a mix of correct and incorrect claims. The Scharff confirmation technique resulted in more new information than the Scharff disconfirmation/confirmation technique and the direct approach. Sources interviewed using the Scharff techniques had a more difficult time reading the interviewer’s information objectives and underestimated their contribution of new information. Sources interviewed using the direct approach overestimated how much new information they revealed. In Study III (N = 200) the interview techniques were used with four different types of sources varying in both their levels of cooperation and capability to provide information as follows: (a) less willing/less able, (b) less willing/more able, (c) more willing, less able, and (d) more willing/more able. The Scharff technique was compared to the direct approach. Overall, the Scharff technique resulted in relatively more new information, particularly when interviewing less cooperative sources. Furthermore, sources interviewed using the Scharff technique had a more difficult time reading the interviewer’s information objectives and consistently underestimated their contribution of new information. This thesis provides a psychological framework for and a conceptualization of the Scharff technique. Furthermore, the thesis introduces an experimental set-up mirroring a human intelligence interaction and offers a new set of dependent measures for mapping the efficacy of intelligence gathering techniques. In sum, this thesis provides support for the Scharff technique as an effective tool for eliciting information from human sources.

Studies have demonstrated the efficacy of the Scharff technique for gathering human intelligence, but little is known about how this efficacy might vary among different samples of practitioners. In this training study we examined a sample of military officers (n = 37). Half was trained in the Scharff technique and compared against officers receiving no Scharff training. All officers received the same case file describing two sources holding information about a terrorist attack. University students (n=74) took the role of the semi-cooperative sources. Scharff-trained officers adhered to the training as they (1) aimed to establish the ‘knowing-it-all’ illusion, (2) posed claims as a means of eliciting information, and (3) asked fewer explicit questions. The ‘untrained’ officers asked many explicit questions, questioned the reliability of the provided information, pressured the source, and displayed disappointment with the source’s contribution. Scharff-trained officers were perceived as less eager to gather information and left their sources with the impression of having provided comparatively less new information, but collected a similar amount of new information as their untrained colleagues. The present paper both replicates and advances previous work in the field, and marks the Scharff technique as a promising technique for gathering human intelligence.

Obtaining detailed accounts from individuals who have witnessed complex events under challenging encoding conditions presents a difficulty for investigators. In the present research, participants (N = 132) reported their recall of an event witnessed under full or divided attention using a timeline reporting format. Extending the timeline technique to assess the relative performance of two additional mnemonics—self-generated cues (SGC) and other-generated cues (OGC)—participants provided an account across three timeline reporting conditions comparing the efficacy of SGC, OGC, and no cues (control). Mock-witnesses using SGC provided more correct details than mock-witnesses in the OGC or no-cues conditions, under full but not under divided attention conditions. There was no difference between cue conditions with respect to the number of errors reported across attention conditions. Findings show SGC to be a promising addition to interviewing techniques as a retrieval support mnemonic with implications for applied contexts.

Neglected Perspectives on Science and Religion explores historical and contemporary relations between science and religion, providing new perspectives on familiar topics such as evolution and the Galileo affair. The book also explores common differences in science and religion with respect to their various treatments of doubt, curiosity, and the methods by which truth claims are assessed. The book includes discussions of religious and scientific treatments of the origins of males and females, evolving views of sex and gender, and contemporary tensions about topics such as same-sex marriage. Viney and Woody also include a chapter exploring the effects of social science research on religious topics such as prayer, prejudice, and violence. The rise of social sciences such as psychology, sociology, and anthropology has resulted in discoveries that contribute to new ways of thinking about the relations of science and religion. This book is ideal for graduate and upper-level undergraduate students, as well as anyone interested in science and religion.

Purpose. In previous laboratory-based work, the Scharff technique has proved successful for gathering intelligence from human sources. However, little is known about whether the technique can be taught to practitioners, and whether Scharff-trained practitioners will interview more effectively than colleagues using their conventional approaches and tactics. Method. 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 compared against handlers receiving no Scharff training and free to use the approaches they saw fit. All handlers received the same case file describing a source holding information about a future terrorist attack and were given the same interview objectives. Police trainees (n = 64) took on the role of semicooperative sources and were given incomplete information about the attack. Results. The trained handlers adhered to the Scharff training as they (1) aimed to establish the illusion of 'knowing-it-all', (2) posed claims to collect information, and (3) asked few (if any) explicit questions. In contrast, the untrained handlers tried to evoke the sources' motivation to reveal information and asked a high number of explicit questions. Scharff-trained handlers were perceived as less eager to gather information, but collected comparatively more new information. Conclusions. The Scharff-trained interviewers utilized more specific elicitation tactics (e.g., posing claims) and fewer general interview strategies (e.g., evoking motivation), and they collected comparatively more new information. This captures the essence of the Scharff technique: It is subtle, yet effective. Gathering information from human sources is a fundamental and unceasing endeavour in the prevention of crime. However, researchers have only recently begun to develop and evaluate methods for gathering human intelligence (Evans et al.,

The discovery of many cases of wrongful conviction in the criminal justice system involving admissions from innocent suspects has led psychologists to examine the factors contributing to false confessions. However, little systematic research has assessed the processes underlying Human Intelligence (HUMINT) interrogations relating to military and intelligence operations. The current article examines the similarities and differences between interrogations in criminal and HUMINT settings, and discusses the extent to which the current empirical literature can be applied to criminal and/or HUMINT interrogations. Finally, areas of future research are considered in light of the need for improving HUMINT interrogation.

Although analysts and interpreters have been recognized as critical members of human intelligence (HUMINT) interrogation teams, their perceptions of the interrogation process have yet to be explored in any systematic way. In a series of two studies, we interviewed a small number of highly experienced HUMINT analysts and surveyed a group of interpreters with experience supporting interrogations, about their experience with and perceptions of the interrogation process. We explored a variety of topics with each group, including training and selection, role and function, how best to utilize an analyst/interpreter, logistics (e.g., analyst models and interpreter placement), third-party observations/feedback, perceived effectiveness of interrogation techniques, and team dynamics. The results of these studies may be used to establish, for the first time, baseline knowledge and reported best practices about the HUMINT interrogation process from the analyst and interpreter perspectives, which may ultimately influence training and practice models.

Three techniques for eliciting intelligence from human sources were examined. Two versions of the Scharff-technique (conceptualized as four tactics) were compared against the Direct Approach (open and direct questions). The Scharff confirmation technique used correct claims to elicit information, and the Scharff disconfirmation/confirmation technique used a mix of correct and incorrect claims. The participants (N = 119) took the role of ‘sources’ holding information about a terrorist attack and tried not to reveal too much or too little information during an interview. The Scharff confirmation resulted in more new information than the Scharff disconfirmation/confirmation and the Direct Approach. The sources in the Scharff conditions had a more difficult time reading the interviewer's information objectives. The sources in the Scharff conditions underestimated, whereas sources in the Direct Approach overestimated, how much new information they revealed. The study advances previous work and shows that the Scharff-technique is a promising intelligence gathering technique. Copyright © 2014 John Wiley & Sons, Ltd.

The task force that led to the creation of the High-Value Detainee Interrogation Group (HIG) recommended that the HIG fund a program of research aimed at establishing scientifically supported interrogative best practices. One of the ways to identify ‘best practices’ is to rely on direct reporting from subject-matter experts. In this study, 42 highly experienced military and intelligence interrogators were interviewed about their interrogation-related practices and beliefs, including such topics as training and selection, the role of rapport, perceptions regarding the techniques employed, lie detection, and the roles of interpreters and analysts. Interrogators indicated that excellent interpersonal skills on the part of an interrogator, an emphasis on rapport and relationship-building techniques, and the assistance of well-prepared interpreters and analysts are key components of a successful interrogation. It is our hope that the results of this study will stimulate research, influence training models, and ultimately contribute toward an interrogative best-practice model.

Chapter
People are generally poor at detecting deceit when observing someone’s behaviour or listening to their speech. In this chapter I will discuss the major factors (pitfalls) that lead to failures in catching liars: the sixteen reasons I will present are clustered into three categories: (i) a lack of motivation to detect lies; (ii) difficulties associated with lie detection; and (iii) common errors made by lie detectors. Discussing pitfalls provides insight into how lie detectors can improve their performance (for example, by recognising common biases and avoiding common judgment errors). The second section of this chapter discusses 11 ways (opportunities) to improve lie detection skills. Within this section, I first provide five recommendations for avoiding common errors in detecting lies. Next, I discuss recent lie detection research that introduces novel interview styles aimed at eliciting and enhancing verbal and nonverbal differences between liars and truth tellers. The recommendations are relevant in various settings, from the individual level (e.g., “Is my partner really working late?”) to the societal level (e.g., “Can we trust this suspect when he claims that he is not the serial rapist the police are searching for?”).

Four types of coercive and noncoercive interview strategies (legalistic, physical, cognitive and social) used to facilitate disclosure by high value detainees were examined in an international sample of practitioners and detainees (N = 64). Predictive analyses confirmed that the accusatorial approach was positively correlated with physically coercive strategies (rs = .58) and negatively with forms of social persuasion (rs = −.31). In response to social strategies, detainees were more likely to disclose meaningful information [odds ratio (OR) = 4.2] and earlier in the interview when rapport-building techniques were used (OR = 14.17). They were less likely to cooperate when confronted with evidence (OR = 4.8). Disclosures were more complete in response to noncoercive strategies, especially rapport-building and procedural fairness elements of respect and voice. These findings augmented past theory on interactional processes and the evidence-base of international best practices in suspect interviews. Copyright © 2014 John Wiley & Sons, Ltd.

Traditional police–suspect interviews differ from intelligence interviews in several important ways, and these differences merit new research activities. This article presents an overview of recent and innovative research into eliciting information and cues to deceit in intelligence interviews, and discusses research into new domains including ‘lying about intentions’, ‘undercover interviewing’, and ‘collective interviewing’. Although that research is still in its infancy, the findings reveal that truth tellers' and liars' answers can be distinguished from each other if the correct interview protocols are implemented, such as asking unexpected questions and introducing forced turn-taking. In addition, this new research also shows that the so-called Scharff technique is more effective for eliciting human intelligence information compared with more traditional techniques.

A common strategy in interviewing is to repeatedly focus on the same topics, for example by asking to recall an event first in chronological order and then in reverse order. We examined the effect of changing interviewers between the two questions or keeping the same interviewers throughout on cues to deception. Truth tellers may be most encouraged to recall again what they have witnessed when confronted with new interviewers, as these new interviewers have not heard their story before. Liars may be most encouraged to recall again their story when confronted with the same interviewers, realising that these interviewers will check for consistency in their answers. The impact of changing interviewers should lead to more pronounced differences between truth tellers and liars in terms of detail and repetition in the ‘Changed Interviewers’ condition compared with the ‘Same Interviewers’ condition. Participants were interviewed by two interviewers about a mock security meeting they attended. In half the interviews, the same two interviewers remained throughout, and in the other half, two new interviewers took over half-way through. As predicted, differences between truth tellers and liars in terms of detail and repetition were most pronounced in the ‘Changed Interviewers’ condition. Changing interviewers during an interview effectively differentiates liars and truth tellers with respect to detail and repetition. We discuss this finding and its place within investigative interviewing and deception detection literature. Copyright © 2014 John Wiley & Sons, Ltd.
