Elasticity in evaluations of criminal evidence: Exploring the role of cognitive dissonance

Purpose. Previous experiments have demonstrated asymmetrical scepticism in investigators' judgments of criminal evidence – evidence inconsistent (vs. consistent) with the dominant hypothesis about a case is judged as less reliable. In addition, some types of evidence (e.g., witness testimony) are more susceptible to asymmetrical scepticism than others (e.g., DNA evidence), indicating varying degrees of elasticity. This article proposes that inconsistent evidence arouses cognitive dissonance, and that the dissonance can be reduced through either asymmetrical scepticism (for high‐elasticity evidence) or belief change (for low‐elasticity evidence). The hypotheses are tested in two experiments. Methods. In both experiments, law students made a preliminary judgment about the guilt of a suspect in a homicide case, and subsequently received a piece of DNA or witness evidence which was either consistent or inconsistent with the preliminary judgment. The extent to which participants changed their guilt judgments, judged the additional evidence as reliable, and felt dissonance served as the main dependent variables. Results. Inconsistent (vs. consistent) evidence did arouse stronger dissonance, but only for witness (and not DNA) evidence. Experienced dissonance (Experiment 1) and dissonance reduction (Experiment 2) accounted for the effect of the evidence on changes in guilt judgments, but not for the effect on reliability judgments. The greatest dissonance reduction was observed among participants who received inconsistent witness evidence but did not change their guilt judgments accordingly. Conclusions. It appears that dissonance plays a significant, although complex, role in investigative judgments of guilt and reliability. Alternative dissonance‐reducing mechanisms that can account for the findings and practical implications are discussed.     

International Technology Cooperation: The Problem of Commercial Rivalry

International technology cooperation promises to help countries exploit the potential of new innovations, but commercial rivalry between companies and governments raises obstacles to it. In this article, I present and solve a model of international technology cooperation. The formal analysis shows that a technology agreement must address two issues. First, governments must be able to induce companies to innovate. Second, governments must credibly commit to penalizing companies for failing to share new information produced through research. Based on these observations, I show that the potential for technology cooperation is maximized in symmetric settings between equally capable governments and companies. In practice, this observation warrants a policy focus on countries and industries that are already on a level playing ground. I also consider extensions to multinational companies and adverse selection problems. The formal analysis provides a solid foundation for practical policy implementation.     

Special Interests,Regulatory Quality,and the Pesticides Overload

Pesticides overuse is a serious threat to ecosystems and wildlife, human health, and agricultural sustainability. So far, however, social scientists have not produced systematic evidence on the political–economic determinants of pesticides overuse. We argue that the agrochemical industry, as a profit‐motivated interest group, will only mobilize politically to avoid reductions in pesticides use when regulatory institutions are potentially capable of correcting a market failure. If regulatory institutions are weakened by corruption or other factors, pesticides overuse occurs with or without the influence of the agrochemical industry. We test this interactive theory systematically against quantitative data on pesticides use in 24 Organisation for Economic Co‐operation and Development countries, 1991–2003. Using corruption and other indicators to capture bureaucratic quality, we find substantively large and statistically robust interactive effects. The agrochemical industry is a crucial determinant of pesticides use in nations with low corruption, whereas the agrochemical industry has no effect on pesticides use under corrupt regulatory institutions. Troublingly, these results imply that reduced corruption may not improve actual regulatory effectiveness unless political institutions can somehow constrain the influence of special interests.     

Reformperspektiven für den Bundesrat

Eine Ländermitwirkung an der oberstaatlichen Willensbildung (insb Gesetzgebung) gehört unbestreitbar zu den Merkmalen eines (echten) Bundesstaates. Über die Formen und Wege, vor allem über die Gegenstände und die Intensität einer solchen Länderbeteiligung wird seit längerem in Wissenschaft und Öffentlichkeit kontrovers diskutiert. Das Vorhaben der neuen Koalitionsregierung für eine "Staatsreform" gibt Anlass zu neuerlicher Reflexion. Der Beitrag unterzieht die wesentlichsten früheren Reformideen (einschließlich jener im Österreich-Konvent und der Äusserung des Bundespräsidenten von 2005) einer kritischen Analyse und rechtspolitischen Bewertung. Abschließend werden Möglichkeiten einer Verbesserung und Flexibilisierung der Entscheidungsverfahren im Bundesstaat erörtert.     

Streiflichter zum Verhältnis von Parlamentsakten und EMRK

Dieser Beitrag untersucht die Beziehung zwischen Parlamentsakten und der Europäischen Menschenrechtskonvention. Dabei wird beleuchtet, wie verschiedene Parlamentsakte in ein Spannungsverhältnis zu den Vorgaben der Europäischen Menschenrechtskonvention treten können. Die vorliegende Arbeit behandelt die maßgebliche Rechtslage hinsichtlich der österreichischen Parlamente bzw deren Mitglieder auf Bundes- sowie Landesebene.     

Antecedents of political market orientation in Britain and Sweden: analysis and future research propositions

• During the last 20 years, political marketing has become a widespread phenomenon around the world. However, most of the research concerning political marketing has been carried out in countries such as the United States and Britain. Thus, in order to understand the antecedents of political marketing, as well as its effectiveness as an electoral strategy, there is a need for comparative research including countries that differ significantly from the U.S. and Britain.
• One such country is Sweden. Thus, the purpose of this article is to compare and analyze Sweden and Britain with regard to two analytical research questions: (1) What differences are there between Britain and Sweden that might be relevant in understanding why parties choose to be sales‐ or market‐oriented? (2) What are the implications with regards to differences between countries and between parties within countries that might help to explain why some parties in some countries are more likely than others to be market‐oriented?

The Intergenerational Cycle of Criminality—Association with Psychopathy*

Abstract: Preventive interventions early in life are likely to lower the risk of intergenerational transmission of criminal behavior. We investigated if psychopathy among homicidal offenders is associated with criminal offending among the offenders’ offspring. The basic sample consisted of consecutive Finnish homicide offenders (during 1995–2004) who had been subjected to a forensic psychiatric examination and rated for a file‐based PCL‐R, and their offspring. Criminal behavior among both genders of the offspring was more common than in the general population. In general, the offspring’s crimes against others (e.g., threat, intimidation, deprivation of freedom, breach of domicile) were associated with their parent’s psychopathy. A grandfather’s major mental disorder was associated with a high rate of crime committed by the offspring. Especially, the sons of male psychopathic homicidal offenders had the highest rate of committing crimes, which was often expressed as vandalism. However, both genders of offspring seem to require special preventive programs to ameliorate these problems.     

Latent Profile Approach to Duration of Stalking

Abstract: Stalking behavior and victim–stalker relationship are often the principal known factors in a stalking case. Thus, they are of great importance when trying to identify factors contributing to stalking duration. The present study aims to identify distinct subgroups of stalking victims based on measures of behavioral stalking dimensions. These victim subgroups, stalking dimensions, and victim–stalker relationship are examined in relation to stalking duration. Using a sample of 137 university students, latent profile analysis (LPA) revealed five distinct victim subgroups based on stalker behavior dimensions: surveillance, low‐profile, social lurker, wide scope, and baseline stalkers. The subgroups were significantly related to stalking duration and explained a considerable amount of the variance along with the stalking dimensions and victim–stalker relationship. Connections to stalking literature and utility of person‐orientated methods in stalking research are discussed.     

Characteristic Features of Severe Child Physical Abuse—A Multi-informant Approach

Minor child physical abuse has decreased in Sweden since 1979, when a law banning corporal punishment of children was passed, but more serious forms have not decreased. The aim of this study was to examine risk and background factors in cases of severe child abuse reported to the police. Files from different agencies (e.g., Social services, Adult and Child psychiatry and Pediatric clinic) for 20 children and 34 caretakers were studied. An accumulation of risk factors was found. It is concluded that when the following four factors are present, there is a risk for severe child abuse: 1) a person with a tendency to use violence in conflict situations; 2) a strong level of stress on the perpetrator and the family; 3) an insufficient social network that does not manage to protect the child; 4) a child that does not manage to protect him or herself. Thus, multiple sources of information must be used when investigating child abuse.     

Socialisation to interdisciplinary legal education: an empirical assessment

This article provides novel empirical survey evidence on socialisation factors leading lecturers to implement interdisciplinary teaching in law. Recent debates on legal scholarship and higher education legal institutions advocate the introduction of interdisciplinary approaches to legal studies. Nevertheless, there is still little evidence of how this lecturing philosophy might be affected by socialisation with other disciplines. To address this, we analyse the case of external lecturers in the Faculty of Law at the University of Copenhagen in Denmark, who constitute the majority of the teaching staff in this institution. To explain the adoption of interdisciplinary teaching, we rely on socialisation factors connected to their former higher education and socialisation in research and multidisciplinary environments.
