The Effect of Jury Deliberations on Jurors' Reasoning Skills

The effect of jury deliberation on jurors' reasoning skill in a murder trial was examined. Specifically, the effect of deliberating on reasoning competence (as defined by Kuhn, Weinstock and Flaton, 1994) was explored. One hundred and four participants viewed a videotaped murder trial and either deliberated in 12-person juries or ruminated on the case individually. Among those assigned to juries, half had their reasoning skill assessed prior to deliberations, while the others were tested after deliberating. Jurors in the individual rumination condition were assessed after they had the opportunity to reflect on the case alone. As hypothesized, post-group-deliberation jurors were more likely to discount both the selected verdict and alternative theories and incorporate judgmental supporting statements than were the other mock jurors. However, the mock jurors did not differ with regard to making statements that supported alternative verdicts or including judgmental statements that discounted their chosen verdict. In terms of Kuhn's reasoning continuum from satisficing (low level) to theory–evidence coordination (high level), there is some evidence that post-group-deliberation jurors may be closer to the high end than predeliberation jurors or post-individual-rumination jurors in some aspects of the task, but not in others.     

Why do only some people who support parties actually join them? Evidence from Britain

What makes people join a political party is one of the most commonly studied questions in research on party members. Nearly all this research, however, is based on talking to people who have actually joined parties. This article simultaneously analyses surveys of members of political parties in Britain and surveys of non-member supporters of those same parties. This uniquely enables us to model the decision to join parties. The results suggest that most of the elements that constitute the influential ‘General Incentives Model’ are significant. But it also reveals that, while party supporters imagine that selective benefits, social norms and opposing rival parties’ policies are key factors in members’ decisions to join a party, those who actually do so are more likely to say they are motivated by attachments to their party’s values, policies and leaders, as well as by an altruistic desire to support democracy more generally.

Assessing callous–unemotional traits in adolescent offenders: Validation of the Inventory of Callous–Unemotional Traits

The presence of callous–unemotional (CU) traits designates an important subgroup of antisocial youth. To improve upon existing measures, the Inventory of Callous–Unemotional Traits (ICU) was developed to provide an efficient, reliable, and valid assessment of CU traits in samples of youth. The current study tests the factor structure and correlates of the ICU scale in a sample (n = 248) of juvenile offenders (188 boys, 60 girls) between the ages of 12 and 20 (M = 15.47, SD = 1.37). Confirmatory factor analyses are consistent with the presence of three independent factors (i.e., Uncaring, Callousness, and Unemotional) that relate to a higher-order callous–unemotional dimension. Also, CU traits overall showed associations with aggression, delinquency, and both psychophysiological and self-report indices of emotional reactivity. There were some important differences across the three facets of the ICU in their associations with these key external criteria.     

Parents, Friends, and Romantic Partners: Enmeshment in Deviant Networks and Adolescent Delinquency Involvement

Adolescent networks include parents, friends, and romantic partners, but research on the social learning mechanisms related to delinquency has not typically examined the characteristics of all three domains simultaneously. Analyses draw on data from the Toledo Adolescent Relationships Study (n = 957), and our analytic sample contains 51% male and 49% female as well as 69% white, 24% African-American, and 7% Latino respondents. Parents,’ peers,’ and partners’ deviance are each related to respondents’ delinquency, and affiliation with a greater number of deviant networks is associated with higher self-reported involvement. Analyses that consider enmeshment type indicate that those with both above average romantic partner and friend delinquency report especially high levels of self-reported involvement. In all comparisons, adolescents with deviant romantic partners are more delinquent than those youths with more prosocial partners, regardless of friends’ and parents’ behavior. Findings highlight the importance of capturing the adolescent’s entire network of affiliations, rather than viewing these in isolation, and suggest the need for additional research on romantic partner influences on delinquent behavior and other adolescent outcomes.

Using Social Science to Inform the Law of Intestacy: The Case of Unmarried Committed Partners

Laws of intestate succession determine how the estate of a person who dies without a will is distributed. Researchers have struggled with the question of how to infer the donative intent of persons who die intestate. Based on an empirical study of unmarried committed partners, we compare the usefulness of two methods of social research for informing intestacy law: will studies and interviews with living persons about their preferences for estate distribution. The results indicate that for some groups of unmarried committed partners, will studies may not adequately reflect the extent to which intestate decedents wish their partner to share in their estate. In addition, the results demonstrate a close correspondence between respondents' actual wills, when they had them, and their distributive preferences on hypothetical scenarios. These findings are discussed as they relate to an examination of which sources of social scientific evidence are most useful in informing the law of intestacy.
