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.     

International institutions and market expectations: Stock price responses to the WTO ruling on the 2002 U.S. steel tariffs

Many scholars assert that international institutions have little power to enforce laws, punish offenders, or force compliance. Others stress that international institutions are important actors, specifically in the regulation of international trade. In this paper, I show that the recent trade dispute over U.S. steel protection provides us with a critical case to evaluate the role of the World Trade Organization in settling trade disputes and specifically stabilizing expectations of market actors over future steel policy. I argue that stock prices can serve as an important tool in answering these questions. In an empirical analysis using daily steel stock prices, I find that during the 2002 WTO steel case, the WTO dispute mechanism helped market actors stabilize expectations of future trade policy.

Projection effects and strategic ambiguity in electoral competition

Theories from psychology suggest that voters’ perceptions of political positions depend on their non-policy related attitudes towards the candidates. A voter who likes (dislikes) a candidate will perceive the candidate’s position as closer to (further from) his own than it really is. This is called projection. If voters’ perceptions are not counterfactual and voting is based on perceived policy positions then projection gives generally liked candidates an incentive to be ambiguous. In this paper we extend the standard Downsian model in order to investigate under what conditions this incentive survives in the strategic setting of electoral competition.     

Childhood and Adolescent Predictors of Late Onset Criminal Careers

This study explores the emergence of a criminal career in adulthood. The main hypothesis tested is that late criminal onset (at age 21 or later) is influenced by early factors that delay antisocial manifestations. The Cambridge Study in Delinquent Development (CSDD) was used to examine early determinants of criminal behavior. 400 Inner London males were followed from ages 8–10 to 48–50, and were classified as follows: 35 late onsetters who were first convicted at age 21 or later, and did not have high self-reported delinquency at ages 10–14 and 15–18; 129 early onsetters first convicted between ages 10 and 20; and 236 unconvicted males. Odds ratios and logistic regression analyses revealed that the best predictors of late onset offenders compared with early onset offenders included nervousness, having few friends at ages 8–10, and not having sexual intercourse by age 18. The best predictors of late onset offenders compared with nonoffenders included teacher-rated anxiousness at ages 12–14 and high neuroticism at age 16. It is concluded that being nervous and withdrawn protected boys against offending in adolescence but that these protective effects tended to wear off after age 21. These findings show that adult offending can be predicted from childhood, and suggest that early intervention might prevent a variety of maladjustment problems and difficulties in adult life.
