Sorting Insiders From Co-Workers: Remote Synchronous Computer-Mediated Triage for Investigating Insider Attacks

OBJECTIVE

Develop and investigate the potential of a remote, computer-mediated and synchronous text-based triage, which we refer to as InSort, for quickly highlighting persons of interest after an insider attack.

BACKGROUND

Insiders maliciously exploit legitimate access to impair the confidentiality and integrity of organizations. The globalisation of organisations and advancement of information technology means employees are often dispersed across national and international sites, working around the clock, often remotely. Hence, investigating insider attacks is challenging. However, the cognitive demands associated with masking insider activity offer opportunities. Drawing on cognitive approaches to deception and understanding of deception-conveying features in textual responses, we developed InSort, a remote computer-mediated triage.

METHOD

During a 6-hour immersive simulation, participants worked in teams, examining password protected, security sensitive databases and exchanging information during an organized crime investigation. Twenty-five percent were covertly incentivized to act as an 'insider' by providing information to a provocateur.

RESULTS

Responses to InSort questioning revealed insiders took longer to answer investigation relevant questions, provided impoverished responses, and their answers were less consistent with known evidence about their behaviours than co-workers.

CONCLUSION

Findings demonstrate InSort has potential to expedite information gathering and investigative processes following an insider attack.

APPLICATION

InSort is appropriate for application by non-specialist investigators and can be quickly altered as a function of both environment and event. InSort offers a clearly defined, well specified, approach for use across insider incidents, and highlights the potential of technology for supporting complex time critical investigations.

Exploring how members of illicit networks navigate investigative interviews

This study explored how members of an illicit network navigate investigative interviews probing their crimes. We examined how perceived disclosure outcomes, namely, the projected costs and benefits, affect what members choose to reveal. We recruited N = 22 groups, maximum of six participants per group. Each group assumed the role of an illicit network and planned for possible interviews with investigators probing into the legitimacy of a business the network owns. All participants underwent an interview after the group planning stage. The results indicated that network members navigate the dilemma interviews bring by disclosing information they perceive would likely yield beneficial (or desirable) rather than costly (or undesirable) outcomes. Additionally, much of the participants' sensitivity to potential costs and benefits was explained by the group of which they are a part: different networks likely respond to costs and benefits in unique ways. This work contributes to understanding how illicit networks manage information disclosure in investigative interviews.

Verbal Lie Detection: Its Past, Present and Future

This article provides an overview of verbal lie detection research. This type of research began in the 1970s with examining the relationship between deception and specific words. We briefly review this initial research. In the late 1980s, Criteria-Based Content Analysis (CBCA) emerged, a veracity assessment tool containing a list of verbal criteria. This was followed by Reality Monitoring (RM) and Scientific Content Analysis (SCAN), two other veracity assessment tools that contain lists of verbal criteria. We discuss their contents, theoretical rationales, and ability to identify truths and lies. We also discuss similarities and differences between CBCA, RM, and SCAN. In the mid 2000s, 'Interviewing to deception' emerged, with the goal of developing specific interview protocols aimed at enhancing or eliciting verbal veracity cues. We outline the four most widely researched interview protocols to date: the Strategic Use of Evidence (SUE), Verifiability Approach (VA), Cognitive Credibility Assessment (CCA), and Reality Interviewing (RI). We briefly discuss the working of these protocols, their theoretical rationales and empirical support, as well as the similarities and differences between them. We conclude this article with elaborating on how neuroscientists can inform and improve verbal lie detection.

Psychological contributions to cold case investigations: A systematic review

This article presents a systematic review of the available literature on 'what works' in cold case investigations, with a specific focus on psychological evidence-based research. Long-term unsolved and cold cases present their own unique set of challenges, such as lack of hard evidence, recall accuracy, and witness credibility. Therefore, this review provides a collated base of research regarding preventative methods and investigative tools and techniques developed to highlight gaps in the literature and inform best practice in cold case investigations. The review features victim and crime characteristics that may contribute to a case becoming cold and displays contributing factors to cold case clearance. Although promising, at present, psychological research in this field is insufficient to inform evidence-based guidance. Future research should aim to explore the wider psychological and criminal justice-based literature (e.g., memory retrieval and cognitive bias) to investigate what could be applicable to cold case investigations.

Police-suspect interactions and confession rates are affected by suspects' alcohol and drug use status in low-stakes crime interrogations

Background

Low-stakes crimes related to alcohol and/or drugs are common around the world, but research is lacking on police-suspect interactions of such crimes. A large proportion of these suspects are intoxicated during interrogations, and many may have substance use disorder, making them potentially vulnerable to interrogative pressure.

Methods

To address this lack of knowledge, the taxonomy of interrogation methods framework (i.e., 60+ interrogation techniques classified into five domains) and a common classification of question types (appropriate vs. inappropriate) were applied in the coding of written police interrogations. Two archival studies, one pilot (Study 1, N = 39) and one main study (Study 2, N = 97) analyzed police interrogations with suspects of alcohol- and drug-related crimes in Sweden.

Results

For both Study 1 and 2, suspects showed signs of alcohol and/or drug intoxication, hangover or withdrawal in more than 50% of all interrogations. In Study 2, additional coding indicated that suspects displayed signs of substance use disorder in 57% of the interrogations. The main results from both studies revealed a large number of direct questions asked by the police across all interrogations, and relatively little use of the strategic interrogation techniques from the taxonomy of interrogation methods framework. In fact, when it came to interrogation techniques, law enforcement used more confrontational techniques in their interactions with intoxicated suspects compared to sober suspects. Furthermore, suspects displaying signs of substance use disorder were significantly more cooperative and prone to confess than suspects without indicators of substance use disorder.

Conclusion

As the first novel study on low-stakes crime interrogations related to alcohol and/or drugs, the present study provides useful information about current Swedish interrogation practices and areas for improvement. The study results indicate that suspects displaying signs of intoxication or substance use disorder may be more vulnerable during police interrogations. This may in turn have the potential to inform the development of new interrogation policies. Due to the novelty of this research, more studies are needed, both on a national and international level, to examine interrogations in low-stakes crimes further.

Police Officers' Interrogation Expertise and Major Objectives in Police Service and Training: A Comprehensive Overview of the Literature

Interrogation is a core task of practical police work. The outcomes of interrogation often provide crucial evidence for solving criminal cases. The success of interrogation depends on interactions between police officers and citizens. Based on a comprehensive literature overview, we propose a three-factor typology for interrogations by police officers. First, the competencies of police officers refer to the application of personal, professional, social, and methodological capabilities. The underlying concept of interrogation refers to the application of both explicit and implicit experience-based interrogation models. Communication refers to the goal-directed application of communication tactics and techniques. According to this typology, we discuss the major objectives of police interrogation in police service and training from police officers' perspectives. The present study provides guidance for practical police services and training by offering an evidence-based interrogation standard.

Sleep and interrogation: does losing sleep impact criminal history disclosure?

STUDY OBJECTIVES

Despite centuries of using sleep deprivation to interrogate, there is virtually no scientific evidence on how sleep shapes behavior within interrogation settings. To evaluate the impact of sleeplessness on participants' behavior during investigative interviews, an experimental study examined the impact of sleep restriction on disclosure of past illegal behavior.

METHODS

Healthy participants from a university community (N = 143) either maintained or curbed their sleep (up to 4 h a night) across 2 days with sleep monitored via actigraphy. They were then asked to disclose past illegal acts and interviewed about them. Next, they were reinterviewed following an example of a detailed memory account (model statement). Disclosures were blindly coded for quantity and quality by two independent raters.

RESULTS

Sleep-restricted individuals reported similar offenses, but less information during their disclosure with slightly less precision. Model statement increased disclosure but did not reduce the inhibiting impact of sleep loss. Mediation analysis confirmed the causal role of sleep as responsible for experimental differences in amount of information, and participants' reports suggested impaired motivation to recall information played a role.

CONCLUSIONS

The findings suggest that even moderate sleep loss can inhibit criminal disclosure during interviews, point to motivational factors as responsible, and suggest investigators should be cautious when interrogating sleepy participants.

The effects of a model statement on information elicitation and deception detection in multiple interviews

Researchers started developing interview techniques to enhance deception detection in forensic settings. One of those techniques is the Model Statement, which has been shown to be effective for eliciting information and cues to deception in single interviews. In the current research, we focused on the effect of the Model Statement in multiple interviews. Participants (N = 243) were interviewed three times-each time one week apart-about a genuine (truth tellers) or fabricated (lie tellers) memorable event. They listened to a Model Statement at Time 1, Time 2, Times 1 and 2, or not at all. Hypotheses focused on participants' verbal reports at Time 3 and on unique details provided across the three interviews. In both instances, truth tellers provided more core and total details and complications and fewer common knowledge details and self-handicapping strategies and obtained higher proportion scores of (i) complications and (ii) core details than lie tellers. Complications and proportion of complications were the most diagnostic cues. The Model Statement was effective only when presented at Time 1, resulting in more common knowledge details. No Veracity × Model Statement interaction effects emerged.

Torturing science Science, interrogational torture, and public policy

Contrary to the claims of the Central Intelligence Agency (CIA) that its torture program was scientific, the program was not based on biology or any other science. Instead, the George W. Bush administration veneered the program's justification with a patina of pseudoscience, ignoring the actual biology of torturing human brains. We reconstruct the Bush administration's decision-making process to establish that the policy decision to use torture took place in the immediate aftermath of the 9/11 attacks without any investigation into its efficacy. We then present the pseudoscientific model of torture sold to the CIA, show why this ad hoc model amounted to pseudoscience, and then catalog what the actual science of torturing human brains-available in 2001-reveals about the practice. We conclude with a discussion of how a process incorporating countervailing evidence might prevent a policy going forward that is contrary to law, ethics, and evidence.

Cumulative Disadvantage: A Psychological Framework for Understanding How Innocence Can Lead to Confession, Wrongful Conviction, and Beyond

False confessions are a contributing factor in almost 30% of DNA exonerations in the United States. Similar problems have been documented all over the world. We present a novel framework to highlight the processes through which innocent people, once misidentified as suspects, experience cumulative disadvantages that culminate in pernicious consequences. The cumulative-disadvantage framework details how the innocent suspect's naivete and the interrogator's presumption of guilt trigger a process that can lead to false confession, the aftereffects of which spread to corrupt evidence gathering, bias forensic analysis, and virtually ensure wrongful convictions at trial or through pressured false guilty pleas. The framework integrates nascent research underscoring the enduring effects of the accumulated disadvantages postconviction and even after exoneration. We synthesize findings from psychological science, corroborating naturalistic evidence, and relevant legal precedents to explain how an innocent suspect's disadvantages can accumulate through the actions of law enforcement, forensic examiners, prosecutors, defense attorneys, judges, juries, and appeals courts. We conclude with prescribed research directions that can lead to empirically driven reforms to address the gestalt of the multistage process.

Science or pseudoscience? A distinction that matters for police officers, lawyers and judges

Scientific knowledge has been a significant contributor to the development of better practices within law enforcement agencies. However, some alleged 'experts' have been shown to have disseminated information to police officers, lawyers and judges that is neither empirically tested nor supported by scientific theory. The aim of this article is to provide organisations within the justice system with an overview of a) what science is and is not; b) what constitutes an empirically driven, theoretically founded, peer-reviewed approach; and c) how to distinguish science from pseudoscience. Using examples in relation to non-verbal communication, this article aims to demonstrate that not all information which is presented as comprehensively evaluated is methodologically reliable for use in the justice system.

Reading Lies: Nonverbal Communication and Deception

The relationship between nonverbal communication and deception continues to attract much interest, but there are many misconceptions about it. In this review, we present a scientific view on this relationship. We describe theories explaining why liars would behave differently from truth tellers, followed by research on how liars actually behave and individuals' ability to detect lies. We show that the nonverbal cues to deceit discovered to date are faint and unreliable and that people are mediocre lie catchers when they pay attention to behavior. We also discuss why individuals hold misbeliefs about the relationship between nonverbal behavior and deception-beliefs that appear very hard to debunk. We further discuss the ways in which researchers could improve the state of affairs by examining nonverbal behaviors in different ways and in different settings than they currently do.

Shaping Responses to Torture: What You Call It Matters

Although torture is largely ineffective for gaining information from terrorism suspects, nearly half of Americans support its use. Building upon previous work examining predictors of responses to such tactics and willingness to label them as "torture," this research tested whether the "torture" label itself can influence attitudes. Across five experiments using two different populations, both politically liberal and conservative participants showed more negative attitudes toward "torture" than "enhanced interrogation," even given identical descriptions of the tactics. This greater negativity in response to "torture" extended to actual behavior (signing a petition) and was driven by cognitive appraisals of severity as well as feelings of personal distress and other-directed empathic concern. Furthermore, there was a small but significant effect for such effects to be stronger among conservatives than liberals. These findings have implications for the underpinnings of attitudes toward torture, potential ways to shift such attitudes, and the psychological consequences of labels.
