The effects of judicial admonitions on hearsay evidence

Using a simulated civil case, this experiment investigated whether mock jurors: (a) are able to disregard hearsay evidence when admonished to do so, (b) experience psychological reactance and "backfire effects" in proportion to the strength of judicial admonition instructing them to disregard hearsay evidence, and (c) are able to recognize and disregard hearsay evidence without judicial instructions. Results indicate that jurors were unable to disregard inadmissible hearsay testimony in some legal decisions regardless of whether there were judicial instructions to do so. Jurors exhibited backfire effects paying more attention to inadmissible hearsay evidence when they were strongly instructed to disregard it. More specifically, juror backfire effects were evident in both their confidence in their liability verdicts and in their punitive damage awards. The legal and policy implications of these findings are discussed.     

Firing Back at the Backfire Effect: The Influence of Mortality Salience and Nullification Beliefs on Reactions to Inadmissible Evidence

Two studies were conducted to explore psychological factors that contribute to the influence of inadmissible evidence (i.e., the backfire effect) on jurors' verdicts. On the basis of hypotheses derived from terror management theory, we predicted that reminders of mortality, in contrast to an aversive control topic, should lead participants to be less punitive when confronted with inadmissible (as opposed to admissible) evidence, when participants were either situationally induced or dispositionally prone to follow their personal sense of justice. In Study 1, control participants who scored high on a measure of nullification beliefs, and thus were prone to relying on their own sense of justice rather than the law, exhibited the backfire effect. However, reminding participants of their mortality reduced the damaging influence of inadmissible evidence. Study 2 extended these findings by showing parallel effects with a manipulation of nullification proneness via judicial instructions. The implications of these factors on the judicial process are discussed.     

idPAD: Paper Analytical Device for Presumptive Identification of Illicit Drugs

As drug overdose deaths across the United States continue to rise, there is increasing interest in field testing of illicit substances. This work discusses a paper-based analytical device (idPAD) that can run a library of 12 colorimetric tests at the same time, each detecting different chemical functional groups and materials found in illicit drugs, distractor substances, and cutting agents. The idPAD requires no electricity, costs less than $2 USD, and requires minimal training to operate. The results of the 12 tests form a color barcode which is “read” by comparison to standard images. The accuracy of the idPAD was assessed using samples of heroin, cocaine HCl, crack, and methamphetamine at concentrations of 25%–100% in a lactose matrix, as well as pure lactose. Based on 840 “reads” by three different users, the idPAD showed 95% sensitivity and 100% specificity for detecting these drugs; the most common error was mistaking cocaine HCl for crack or crack for cocaine HCl. In a second step, samples of heroin, cocaine, and methamphetamine (n = 30) and distractor substances (pharmaceuticals, cutting agents, and other illicit drugs, n = 64) were tested by two readers, yielding a sensitivity of 100% and specificity of 97%. Targeted substances were detected reliably at 55–180 μg/lane, and the idPAD was found to be stable for at least 3 months when stored at room temperature. The library approach used in the idPAD may provide the accuracy and robustness necessary for a presumptive field drug test.     

Vicarious Annihilation: The Effect of Mortality Salience on Perceptions of Hate Crimes

Previous research has found that reminding participants of their mortality creates a need for individuals to maintain and defend subjective cultural worldviews. As a result, mortality salient participants typically strive to uphold legal sanctions and also react negatively to individuals who espouse alternative worldview beliefs, exhibiting behaviors toward those targets ranging from verbal derogation to physical aggression. This paper extends this line of research by examining perceptions of hate crimes. Hate crimes represent a unique class of crime where both the perpetrator and victim may be viewed as worldview violators. Study 1 revealed that mortality salient participants were more supportive of hate crime legislation than were control participants when hate crimes were described in abstract terms and no specific victim was mentioned. In Study 2, a specific victim who posed a potential worldview threat was identified. In this case, mortality salient participants were less punitive toward offenders who attacked these specific worldview-threatening victims.     

Conceptualizing and Measuring Ethnic Politics: An Institutional Complement to Demographic, Behavioral, and Cognitive Approaches

The influence of ??ethnic politics?? has been demonstrated in a range of empirical studies of economic growth, violence, and public goods provision. While others have raised concerns about the measurement of ethnic variables in these works, we seek to situate such discussions within a more thoroughgoing conceptual analysis. Specifically, we argue that four conceptual approaches??demographic, cognitive, behavioral, and institutional??have been used to develop theories in which the mechanism that relates causes to outcomes is ethnic political competition. Within this literature, we believe that institutional approaches have been relatively under-appreciated, and we attempt to address that imbalance. We begin by critically reviewing the three main ways in which ethnic variables have been specified and operationalized, delineating the assumptions and trade-offs underlying their use. Next, we describe an institutional approach to the study of ethnic politics, which focuses on the rules and procedures for differentiating ethnic categories. We propose some new indices based on this latter approach that might be developed and used in future research. Subsequently, we analyze the relationship between each of these approaches and patterns of ethnic political competition in a set of six country cases, highlighting their strengths and weaknesses, as well as theoretical links between them.

Barriers to Cross-Systems Collaboration in Child Welfare,Education, and the Courts: Supporting Educational Well-being of Youth in Care Through Systems Change

Cross-systems collaboration between child welfare, education, and the courts benefits when challenges and priorities are identified early. We measured perceptions of educational stability in foster youth with a statewide survey of 1,603 professionals in education, child welfare, and the courts. Results reveal commonalities among perceived challenges to collaboration across systems (e.g., multiple foster care placements; school changes) and differences in perceived importance or significance of a given issue by professional group. Results guided collaborative work in Kansas and may assist other states seeking strategies that inform cross-systems collaboration to improve educational well-being for youth in foster care.
