The social context of violent victimization: A study of the delinquent peer effect

Haynie's (2001) work on the structural dimensions of peer networks demonstrated how the characteristics of networks may influence individual delinquent behavior. This study extends the network approach to the prediction of violent victimization. The National Longitudinal Survey of Adolescent Health (Add Health) is used to examine how the friendship-network characteristics of centrality, density, and popularity affect vulnerability. The findings indicate that central and popular members of dense conventional groups experienced lower levels of violent victimization, while the opposite was true of similarly situated members of delinquent networks. Implications for victimization and research related to the specification of how delinquent peer associations promote vulnerability are discussed.     

Revisiting the Racial Threat Thesis: The Role of Police Organizational Characteristics in Predicting Race‐Specific Drug Arrest Rates

Previous research examining the relationship between structural factors and drug arrest rates has neglected the role of the police organization. A central proposition of racial threat theory is that indicators of a threatening Black population will be associated with law enforcement actions as a form of social control. In order to fully test this proposition, however, organizational aspects of law enforcement beyond size of the police force must be considered. Hence, the present study examines police organizational factors as direct predictors of race‐specific drug arrest rates but also as potential moderators of the effects of structural factors on drug arrest rates. Using data from 260 cities, we find that police organizational factors matter, both directly and as moderators of the association between racial economic competition and Black drug arrest rates. Consistent with expectations derived from racial threat and organizational theory, we find that racial threat measures are associated with Black drug arrest rates under conditions of relatively low organizational control.     

The Forensic Confirmation Bias: A Comparison Between Experts and Novices

A large body of research has described the influence of context information on forensic decision‐making. In this study, we examined the effect of context information on the search for and selection of traces by students (N = 36) and crime scene investigators (N = 58). Participants investigated an ambiguous mock crime scene and received prior information indicating suicide, a violent death or no information. Participants described their impression of the scene and wrote down which traces they wanted to secure. Results showed that context information impacted first impression of the scene and crime scene behavior, namely number of traces secured. Participants in the murder condition secured most traces. Furthermore, the students secured more crime‐related traces. Students were more confident in their first impression. This study does not indicate that experts outperform novices. We therefore argue for proper training on cognitive processes as an integral part of all forensic education.     

How Cross‐Examination on Subjectivity and Bias Affects Jurors’ Evaluations of Forensic Science Evidence

Contextual bias has been widely discussed as a possible problem in forensic science. The trial simulation experiment reported here examined reactions of jurors at a county courthouse to cross‐examination and arguments about contextual bias in a hypothetical case. We varied whether the key prosecution witness (a forensic odontologist) was cross‐examined about the subjectivity of his interpretations and about his exposure to potentially biasing task‐irrelevant information. Jurors found the expert less credible and were less likely to convict when the expert admitted that his interpretation rested on subjective judgment, and when he admitted having been exposed to potentially biasing task‐irrelevant contextual information (relative to when these issues were not raised by the lawyers). The findings suggest, however, that forensic scientists can immunize themselves against such challenges and maximize the weight jurors give their evidence by adopting context management procedures that blind them to task‐irrelevant information.     

A case study in public child welfare: county-level practices that address racial disparity in foster care placement

Racial disproportionality has been a longstanding issue within child welfare. The continued overrepresentation of black children in the foster care system is troubling. The authors of this article conducted a case study of two counties in New York State that have steadily decreased the number of black children in foster care in an effort to identify what aspects of their child welfare practice impacted the decline. The case study employed document analysis, in-depth interviews, and focus groups with child removal decision makers. Utilizing a grounded theory approach to content organization and analysis, several themes emerged as noticeable factors. Some of the most salient themes included preventive services and resources, community collaborations, case practice development, family meetings, workforce diversity, the court system, and, the most unique, blind removal meetings. The themes found in this study present promising practices to assist in decreasing the racial disparity in child welfare removal decisions.     

Analyzing the Psychological and Social Contents of Evidence—Experimental Comparison between Guessing,Naturalistic Observation,and Systematic Analysis

To improve inferences about psychological and social evidence contained in pictures and texts, a five‐step algorithm—Systematic Analysis (SA)—was devised. It combines basic principles of interpretation in forensic science, providing a comprehensive record of signs of evidence. Criminal justice professionals evaluated the usefulness of SA. Effects of applying SA were tested experimentally with 41 subjects, compared to 39 subjects observing naturally (naturalistic observation) and 47 subjects guessing intuitively intuitive guessing group. After being trained in SA, prosecutors and police detectives (N = 217) attributed it a good usefulness for criminal investigation. Subjects (graduate students) using SA found significantly more details about four test cases than those observing naturally (Cohen's d = 0.58). Subjects who learned SA well abducted significantly better hypotheses than those who observed naturally or who guessed intuitively. Internal validity of SA was α = 0.74. Applying SA improved observation significantly and reduced confirmation bias.

Does Hostile Attributional Bias for Relational Provocations Mediate the Short-Term Association between Relational Victimization and Aggression in Preadolescence?

This short-term longitudinal study examined the direct association between relational victimization and relational aggression over a five-month period, and proposed that hostile attributional bias for relational provocations mediated this association. Participants were 140 preadolescents (aged 9 to 11 years) in grades four and five. Relational victimization and relational aggression were assessed from self-reports. Hostile intent attributions were measured from preadolescent's responses to hypothetical provocation situations that depicted ambiguous relational aggression among peers. Concurrent and longitudinal findings revealed that more relationally victimized preadolescents were also more relationally aggressive toward their peers. Hostile attributions partially mediated the concurrent association between relational victimization and relational aggression at T1 only. Boys reported significantly higher levels of physical victimization, physical aggression, and relational aggression than girls. Implications for prevention programs are discussed.

Her research interests include depression in adolescence, resilience among high-risk youth, and the prevention of peer victimization.     

Blind Spots: The Effects of Information and Stakes on Fairness Bias and Dispersion

Mounting empirical research provides evidence of fairness bias and its economic and social effects, where fairness bias refers here to a deviation of claims from unbiased justice due to a personal stake. A far less appreciated issue is dispersion of fairness views and claims, which is also important for its effects on disagreements, empirical analysis, and philosophical theories. This study undertakes a systematic analysis of the effects on fairness bias and dispersion of two variables: stakes and information. Most philosophical and social science analyses related to justice and bias associate heightened bias with increased information and, conversely, impartiality with the elimination of certain information. Less attention has been paid to the opposing impact of information, which is to supply the facts needed to achieve justice more reliably. An important open question is whether, on balance, increased information helps agents to achieve fairer outcomes or whether biased use of such information contributes to less fair outcomes. This study focuses on a set of previously reported experiments that share certain features and subjects them to a new analysis. The results of this analysis suggest that, although information is often used in a self-serving way, increased information can, under certain conditions, contribute to fairness claims becoming less biased and less dispersed, both for stakeholders as well as impartial spectators.     

“He's guilty!”: Investigator Bias in Judgments of Truth and Deception

Detecting deception is an inherently difficult task, but one that plays a critical role for law enforcement investigators in the interrogation room. In general, research has failed to indicate that performance in this domain is improved by training or prior experience. A signal detection framework is applied to the paradigm to better conceptualize the influence of these two factors. We found that although neither factor influenced discrimination accuracy, there was an effect on response bias such that training and prior experience appeared to increase the likelihood of responding deceit as opposed to truth. This investigator bias was observed both in a review of the literature and in this study of North American law enforcement investigators who took part in a forensically based deception-detection task. Possible theoretical mechanisms and practical implications of these findings are discussed.
