Sidetracked by emotion: Observers’ ability to discriminate genuine and fabricated sexual assault allegations

Purpose. Assessing the credibility of reports of sexual victimization – often in the absence of corroboration – presents a significant challenge for legal decision makers. This study examined the accuracy of observers in discriminating genuine and fabricated sexual assault allegations. Further, we examined whether individual differences and cue utilization strategies influenced deception detection accuracy. Methods. Observers (N= 119) evaluated eight (four truthful and four deceptive) written allegations of sexual assault (counterbalanced), and completed a Credibility Assessment Questionnaire (CAQ) and individual differences measures. Results. Results indicated that overall accuracy was below chance (M= 45.3%), and a truth bias was evidenced. Examining the Big Five personality traits, we found that openness to experience and neuroticism were positively associated with accuracy, whereas extraversion was negatively related to accuracy. Further, judgement confidence was negatively associated with accuracy. Conclusions. The present study offers insights into observers’ perceptions of credibility regarding real‐life sexual assault allegations. Implications for legal decision making are discussed.     

POLITICS, INSTITUTIONS, CONSTRUCTIVISM and the EMERGING INTERNATIONAL REGIME for FINANCIAL REGULATION

This article examines the growing number of interconnected international groupings that have been built to regulate global finance over the past quarter century. It suggests that the rationalistic approaches focusing on egoistic actors that have dominated scholarly study of this issue area have contributed to the understimation of the strenght of the regime for regulating global finance. It examines, as an alternative, constructivist approaches that stress the importance of institution.     

Participative leadership and hierarchical structures in multiple perpetrator rape: replicating and extending a scale of influence among offenders

ABSTRACT

This paper replicates and extends Porter and Alison’s (2001. A partially ordered scale of influence in violent group behavior: An example from gang rape. Small Group Research, 32(4), 475–497) method of leader identification in Multiple Perpetrator Rape (MPR). The study examined 216 MPR offences (totalling 712 different offenders), collected from archival sources (predominantly law reports). Porter and Alison’s original coding scheme was refined and Multidimensional Scaling identified a partially ordered scale of influence based upon the decisions, actions and orders made by the offenders at each chronological offence stage. The updated scale identified leaders in 97% of the sample groups. The hierarchical structures of the groups were also examined through the distribution of influence among co-offenders. While the majority (68%) of cases exhibited a dichotomous leader/follower structure, some “followers” also exhibited influence tactics to varying degrees with the presence of “lieutenants” and linear hierarchies. The findings are discussed in relation to group dynamics as well as the reliability and validity of the influence scale.     

Dangerous decisions: the impact of first impressions of trustworthiness on the evaluation of legal evidence and defendant culpability

Abstract

There is little support for the long-standing assumption that judges and jurors can accurately assess credibility. According to Dangerous Decisions Theory (DDT; Porter & ten Brinke, Legal and Criminological Psychology, 14, 119–134, 2009), intuitive evaluations of trustworthiness based on the face may strongly bias the interpretation of subsequent information about a target. In a courtroom setting, the assessment of evidence provided by or concerning a defendant may be fundamentally flawed if its interpretation is influenced by an initial, spontaneous assessment of trustworthiness. In an empirical test of DDT, participants were presented with two vignettes describing major or minor crimes, accompanied by a photograph of the supposed defendant, previously rated as highly trustworthy or untrustworthy in appearance. Participants evaluated culpability following the presentation of evidence in each case. Participants required less evidence to arrive at a guilty verdict and were more confident in this decision for untrustworthy-appearing defendants. The current evidence supports DDT and has implications for legal decision-making practices.     

Will get fooled again: Emotionally intelligent people are easily duped by high‐stakes deceivers

Purpose. There is major disagreement about the existence of individual differences in deception detection or naturally gifted detection ‘wizards’ (see O'Sullivan & Ekman, 2004 vs. Bond & Uysal, 2007 ). This study aimed to elucidate the role of a specific, and seemingly relevant individual difference – emotional intelligence (EI) and its subcomponents – in detecting high‐stakes, emotional deception. Methods. Participants (N= 116) viewed a sample of 20 international videos of individuals emotionally pleading for the safe return of their missing family member, half of whom were responsible for the missing person's disappearance/murder. Participants judged whether the pleas were honest or deceptive, provided confidence ratings, reported the cues they utilized, and rated their emotional response to each plea. Results. EI was associated with overconfidence in assessing the sincerity of the pleas and greater self‐reported sympathetic feelings to deceptive targets (enhanced gullibility). Although total EI was not associated with discrimination of truths and lies, the ability to perceive and express emotion (a component of EI), specifically, was negatively related to detecting deceptive targets (lower sensitivity [d′]). Combined, these patterns contributed negatively to the ability to spot emotional lies. Conclusions. These findings collectively suggest that features of EI, and subsequent decision‐making processes, paradoxically may impair one's ability to detect deceit.
