The CSI Effect and the impact of DNA evidence on mock jurors and jury deliberations

ABSTRACT

The present research examined the CSI Effect and the impact of DNA evidence on mock jurors and jury deliberations using a 3 (Crime Drama Viewing: low, moderate, high)?×?3 (Evidence: DNA innocent, DNA guilty, no DNA control) design. A sample of 178 jury-eligible college students read a case of breaking and entering. Pre-deliberation, some support for a CSI Effect was found with high viewers’ extent of guilt ratings significantly lower than moderate and low viewers’ in the no DNA control and the DNA innocent conditions. This effect was not present for verdicts. Contrary to a CSI Effect, crime drama viewing was not related to guilt judgments with incriminating DNA evidence. A content analysis of comments made during deliberations found little support for the CSI Effect entering the jury room. Specifically, CSI Effect predictions were not supported when examining the discussion of DNA evidence, expressing DNA opinions, or mentioning missing evidence. Overall, the limited CSI Effect found for individuals was attenuated during deliberation. The alarm raised over a possible CSI Effect influencing jury decision making may be unwarranted.     

Estimating the speed of vehicles: the influence of stereotypes

Abstract

Davies and Patel (2005, Legal and Criminological Psychology, 10, 45–62) demonstrated that stereotypes associated with particular types of car influenced judgements of culpability in a road accident report. This study explores whether stereotypes influence judgements of the speed of different vehicles. In Experiment 1, participants observed films of a BMW 3 Series and VW Polo being driven at 20, 40 and 60 mph. Accuracy of speed estimates was high and no effect of stereotyping was observed. This finding was replicated in Experiment 2 when the stereotype of a ‘typical’ BMW or Polo driver was instantiated prior to viewing the films and despite participants predicting that the speed of the BMW would be substantially higher than the Polo. In Experiment 3, speed estimates were made unexpectedly a day after viewing the films. In accordance with the stereotype, the BMW was now judged as being driven significantly faster than the Polo at the same actual speed. Consistent with findings from person perception, these results suggest that when unambiguous countervailing information is present, stereotypical influences are minimised or overwhelmed, but much stronger effects occur when access to critical information is impaired or ambiguous. The implications of these findings for witness estimates of vehicle speed are discussed.

Observer reactions to emotional victims of serious crimes: stereotypes and expectancy violations

Negative observer reactions towards victims may be related to people’s expectations of the characteristics and demeanor of an ideal victim. We examined how expressed emotion, victim sex, and type of victimization influence observers’ perceptions of victim credibility, victim character, and harm. Our hypothesis was that angry victims, male victims, and victims of sexual violence are perceived less positively than sad victims, female victims, and victims of physical violence. Additionally, we anticipated that expectancy violations following expressed agentic/high status, or passive/low-status emotions of the victim would lead to negative reactions. Participants (N?=?335) read a written victim impact statement, by a male or female victim of a sexual or physical assault, in which anger or sadness was expressed. The results show that observers generally respond more negatively to male victims than to female victims, and to victims expressing anger rather than sadness. However, a two-way interaction between expressed emotion and type of crime revealed that expressed emotion only significantly influences character derogation and victim credibility in cases of physical violence. Finally, emotion expectancy violations based on ex-ante expectations lead to derogation and diminished credibility. The discussion focuses on how emotion expectancy violations seem intimately tied to stereotype-ridden features of victimization.     

The relationship between antisocial stereotypes and public CCTV systems: exploring fear of crime in the modern surveillance society

Abstract

Situational crime deterrence measures like CCTV are not always associated with reductions in fear of crime. This study explores this unexpected finding by investigating the interaction between target type and the presence of a CCTV camera, in order to test the effect this has on impressions of the target and corresponding fear of the location the target was shown in. Participants (n=120) were shown either a picture of a male ‘skinhead’, a ‘studious’ female, or no one within an urban setting in which an obvious CCTV camera was either present or absent. Participants then rated the scene using scales estimating crime frequency, worry and target activity. Estimates of location safety fell for the male ‘skinhead’ target and activity impressions were more negative, but only when a CCTV camera was also present. Ironically, in some circumstances, public crime deterrence measures may prime pre-existing negative stereotypes about others and so foster suspicion, undermine trust in others, and increase fear of crime.     

A review of the literature on the aging adult skull and face: Implications for forensic science research and applications

This paper is a summary of findings of adult age-related craniofacial morphological changes. Our aims are two-fold: (1) through a review of the literature we address the factors influencing craniofacial aging, and (2) the general ways in which a head and face age in adulthood. We present findings on environmental and innate influences on face aging, facial soft tissue age changes, and bony changes in the craniofacial and dentoalveolar skeleton. We then briefly address the relevance of this information to forensic science research and applications, such as the development of computer facial age-progression and face recognition technologies, and contributions to forensic sketch artistry.     

Strength of Evidence,Extraevidentiary Influence,and the Liberation Hypothesis: Data from the Field

To examine relationships between strength of evidence (SOE) and extraevidentiary variables in the context of Kalven and Zeisel’s (The American Jury, 1966) liberation hypothesis, post-trial questionnaire data were collected from judges, attorneys, and jurors associated with 179 criminal jury trials. SOE ratings were strongly correlated with jury verdicts on the three most serious charges against the defendant, and several extraevidentiary variables (i.e., pretrial publicity, trial complexity, charge severity, and foreperson demographics) were moderately correlated with verdicts. Extraevidentiary-verdict relationships remained significant when SOE was controlled, although extraevidentiary variables yielded only modest improvement in classification accuracy beyond SOE. In partial support of the liberation hypothesis, several case-related extraevidentiary variables were significantly related to jury verdicts only when the prosecution’s evidence was rated as moderately strong.     

Effects of pretrial juror bias,strength of evidence and deliberation process on juror decisions: new validity evidence of the Juror Bias Scale scores

This study examines the validity of the Juror Bias Scale scores in relation to the mock juror decisions reached in two real life homicide cases before and after the deliberation process. The judicial cases used varied in terms of the ambiguity of the evidence presented at both trials. The WLS methodology for statistical modelling of categorical data was used to analyse data. The findings indicated that the Juror Bias Scale scores successfully predict the verdicts and other related questions before and after deliberations in the case with ambiguous evidence. Furthermore, deliberations caused a generalisation effect on the pretrial juror bias in such a case, and enhanced the differences between defense-biased and prosecution-biased jurors in the verdicts delivered after deliberations. The implications of these findings are discussed in relation to the use of pretrial juror bias questionnaires in jury selection.     

Unearthing the realities of rape: Utilising Victorian newspaper reportage to fill in the contextual gaps

This article examines the realities of rape and sexual offences and their treatment through the legal process by use of media reportage, Victorian and modern; using this to contextualise and so to challenge the official record. The starting point is an identification of what constitutes ‹best’ evidence for an exploration of rape and sexual offences – evidence that permits better insights into the impact of such offences on the individuals involved, as well as into the factors governing the ability of the criminal justice process to promote the conviction rate in rape cases. By using a comparative historical perspective, and using media presentations (especially newspaper reportage) this article shows the enduring nature of stereotypes which govern the decisions reached by legal personnel and by jurors – stereotypes which have, since the Victorian period, remained profoundly gendered in ways that are unhelpful to the ‹victims’.     

Attributions of responsibility,blame and justifiability to a perpetrator and victim in an acquaintance rape scenario: the influence of Marijuana intoxication

Abstract

Marijuana is a commonly used illicit drug by young adults and has been implicated in about one third of sexual assaults. However, the influence of Marijuana intoxication on rape attributions has not been previously investigated. This study examined the effects of perpetrator and victim Marijuana intoxication and participant sex on rape attributions. Young adults (N = 285) read an acquaintance rape scenario where Marijuana intoxication was manipulated and completed measures of perpetrator (responsibility, blame and justifiability) and victim attributions (responsibility and blame). The results revealed that an intoxicated, compared to sober, perpetrator was attributed less responsibility for his sexual aggression. When the victim was intoxicated, compared to sober, the perpetrator and victim were attributed less and more blame for the assault, respectively. These findings demonstrate that, irrespective of perceiver sex, Marijuana intoxication, like alcohol intoxication, results in an attributional double standard in favour of the perpetrator.     

Race-Based Judgments, Race-Neutral Justifications: Experimental Examination of Peremptory Use and the Batson Challenge Procedure

Practically speaking, the peremptory challenge remained an inviolate jury selection tool in the United States until the Supreme Court's decision in Batson v. Kentucky. 476 U.S. 79 (1986). Batson's prohibition against race-based peremptories was based on two assumptions: (1) a prospective juror's race can bias jury selection judgments; (2) requiring attorneys to justify suspicious peremptories enables judges to determine whether a challenge is, indeed, race-neutral. The present investigation examines these assumptions through an experimental design using three participant populations: college students, advanced law students, and practicing attorneys. Results demonstrate that race does influence peremptory use, but these judgments are typically justified in race-neutral terms that effectively mask the biasing effects of race. The psychological processes underlying these tendencies are discussed, as are practical implications for the legal system.     

Measuring damages for lost enjoyment of life: the view from the bench and the jury box

Civil jury instructions are inconsistent in defining what constitutes noneconomic damages, which may include pain, suffering, disability, disfigurement, and loss of enjoyment of life (LEL), among other injury sequelae. This inconsistency has been manifested recently in court decisions that have considered whether LEL should be treated as a separate element of noneconomic damages, distinct from pain and suffering. This paper reviews the case law on this issue and also describes a jury simulation experiment. Mock jurors awarded damages after they received instructions on noneconomic damages in which LEL was (1) not identified as a distinct element of damages; (2) defined as an element of damages distinct from pain and suffering, but participants awarded a single amount for noneconomic damages; or (3) defined as a distinct element of damages, and participants awarded separate amounts for LEL and pain and suffering. Instructions about LEL resulted in larger awards, but only when mock jurors also made a separate award for that element of damages.     

Exploring the Genesis of Economic Innovations: The Religious Gestalt-Switch and the Duty to Invent as Preconditions for Economic Growth

This paper discusses changes in the level of knowledge, i.e. learning, as a key source of economic growth, and argues that historically a radical change in attitude towards new knowledge has been a necessary precondition for economic growth. The Renaissance created this radically new attitude in Europe, and this paper discusses contributions to economic theory and economic policy of some of the most influential scientists involved in this process: Francis Bacon (1561-1626) in England, and Leibniz (1646-1716) and Christian Wolff (1679-1754) in Germany. It is argued that these polyhistors viewed economic change as a dynamic knowledge-based process–a view that has important similarities with modern evolutionary or Schumpeterian economics. These similarities have so far not been recognized, and the paper suggests that modern economic theory would benefit from studying the theoretical and practical economics of these philosophers who laid the foundations for the industrial revolution.     

The Insurance Act 2015: Rebalancing the Interests of Insurer and Assured

The Insurance Act 2015 is the first piece of legislation since the eighteenth century to seek to lay down new principles governing the formation and operation of insurance contracts. Exactly 250 years after Lord Mansfield articulated the routinely‐cited principle of utmost good faith in insurance law in Carter v Boehm (1766) 2 Burr 1905, that principle has been recast, with important implications for both the pre‐ and post‐contractual duties of the parties. The Insurance Act has also imposed important restrictions on the enforcement of policy terms by insurers, and clarifies the law affecting fraudulent claims. The Marine Insurance Act 1906, a codifying measure, looks increasingly outmoded.     

Gray Matters: Gender Differences in the Physical and Mental Health of Older Inmates

Although there has been a substantial increase in the number of older female inmates incarcerated in the United States, there has been little scholarly attention paid to this population. The purpose of this study is to extend the current understanding of older inmates by examining gender differences in their physical and mental health. Bivariate analyses of one of the largest known samples of older female inmates (n = 142) revealed significant gender differences. Older female inmates reported a greater number of physical health conditions and mental health disorders in all three time periods: in their lifetimes, since admission to prison, and in the previous year. This research informs the need for gender-specific health programming for older female inmates.     

Moving beyond Ford,Atkins, and Roper: jurors' attitudes toward the execution of the elderly and the physically disabled

Abstract

The central purpose of the current study is to correlate level of support for the death penalty, death-qualification status, attitudes toward the death penalty (ATDP), legal authoritarianism (RLAQ (Revised Legal Attitudes Questionnaire)), and demographic indices with attitudes toward the execution of the elderly and the physically disabled. Two hundred and fifty residents of the 12th Judicial Circuit in Florida completed a booklet that contained the following: (1) one question that measured their level of support for the death penalty; (2) one question that categorized their death-qualification status; (3) the ATDP; (4) the RLAQ; (5) 20 questions that measured participants' attitudes toward the execution of the elderly and the physically disabled (EEPD); and (6) standard demographic questions. Results indicated that level of support for the death penalty, death-qualification status, attitudes toward the death penalty, legal authoritarianism, and demographic indices were significantly related to four components of the EEPD. Legal implications and applications are discussed.     

融贯民商:职务代理的构造逻辑与规范表达 ——《民法总则》第170条释评

职务代理是一项传统的商事代理制度。职务代理权源于被代理人的意定授权,但其范围和类型受到法律规定的限制,被代理人承受职务代理行为的效果是法律规定的结果。我国《民法总则》第170条系以民商合一理念为指导,首次在民法典总则编中明确规定了职务代理规范。在制度功能上,该规范有助于统一司法裁判。但基于职务代理制度的商事属性,该条第1款的适用范围需被限缩,与职务代理有关的商事登记制度还需完善,职务代理权类型还需细化。同时,该条第2款是职务代理制度的特殊规范,适用时应注意它与表见代理和普通无权代理的区分。未来可在《商法通则》中通过建构统一的商事登记规范和对职务代理权的类型化处理,完善职务代理制度。     

The Why and What of Intimate Conflict: Effect of the Partners’ Divergent Perceptions on Verbal Aggression

The aim of this study is to explore the effect on expressions of verbal aggression of intimate partners’ divergent perceptions of what the conflict is about (its subject) and why fight over it (its motive), together with the effect of the period of cohabitation. The study focused on the couple as the unit of analysis. A structured self-report questionnaire was administered to a stratified probability sample drawn from the general population in Israel, including 452 couples (904 men and women). Findings show that there is an association between the couples’ divergent perceptions of the conflict motive and of its subject, and that these disagreements amplify the partners’ aggression toward each other. However, the perception of conflict motive has a stronger effect on the expressions of aggression than that of conflict subject, while duration of cohabitation has a moderating effect on the divergent perceptions of conflict subject and on aggression between the partners. The discussion embraces both the theoretical and practical implications of the findings, as well as the limitations of the study.     

Perceptions of the criminal justice system by minority and majority group university students: The role of ethnic identity

Minorities are overrepresented in the criminal justice system, and prior research has indicated ethnic minorities and Whites have different opinions of and different experiences within the system. While differences have been shown, the influence of ethnic identity on perceptions of the legal system has been overlooked. The purpose of the present research was to determine if there were differences in perceptions of the legal system by ethnic identity levels for ethnic minorities and Whites. Results indicated differences do exist and ethnic identity is a crucial issue in understanding resonance with the legal system. Future directions for incorporating ethnic identity in research on the criminal justice system are discussed.
