Are Judges Influenced by Legally Irrelevant Circumstances

The purpose of this experimental study was to investigate whether this self-image is correct. Swedish judges (N = 256) read a vignette depicting a case of libel, where a female student had claimed on her blog that she had been sexually harassed by a named male professor. The professor had sued the student for libel and the student retracted her claim during the hearing. Half of the judges received irrelevant information - that the professor himself had been convicted of libel a year earlier, while the other half did not receive this information. For the outcome variable, the judges were asked to state how much compensation the student should pay the professor. Those judges who received information about the professor himself having been convicted of libel stated that he should be given significantly less compensation than those who did not receive the irrelevant information. The results show that the judges’ decision was affected by legally irrelevant circumstances. Implications for research and practice are discussed

Experimental participants assessed the relevance of an eyewitness's previous conviction to his credibility in the present case. Results are compared to data from lay judges (n=372). The technique produced a small positive debiasing effect in the sample of Swedish judges, while the effect was negative among lay judges.

Rape victim and perpetrator blame: Effects of immigration status on the attribution of blame toward a rape victim and perpetrator

Lisa Öhman* Department of Psychology, Göteborg University, Box 500, SE 405 30, Göteborg, Sweden, Tel: +46(0)31 786 19 34, E-mail: lisa.ohman@psy.gu.se Pär Anders Granhag Department of Psychology, Göteborg University, Sweden Anders Eriksson Department of Linguistics, Göteborg University, Sweden Earwitness performance has been studied before but not nearly to the extent that eyewitness performance has. This is particularly true for child witnesses. To gain a better understanding of earwitness performance we have designed a study in which children aged 7-8 and 11-12 and adults will serve as informants. A total of 240 participants, will be equally distributed between the three age groups, and exposed to an unfamiliar voice (the planning of a crime). After two weeks, the witnesses will be asked to identify the target-voice in a line-up (7 voices). Half of the ...

Participants from both a community population ( n = 211) and a student population ( n = 200) read a rape vignette and provided their judgements of blame towards a victim and perpetrator, their perception of the event as rape, and later answered the modern racism scale. Results showed a significant positive relationship between modern racism and rape victim blame ( r = .35, R2 [Formula: see text] 100 = 12.1%), while modern racism had a significant negative relationship with perpetrator blame ( r = −.27, R2 [Formula: see text] 100 = 7.5%) and rape perception ( r = −.29, R2 [Formula: see text] 100 = 8.7%). Implications for the criminal justice system as well as suggestions for future research were discussed.

A generalized argument can thus appear more (respectively less) persuasive than one mentioning a specific category instance, provided the argument's claim is more (less) warranted for the prototype than for the instance (positive and negative prototype effect). To investigate this effect in legal contexts using mock-scenarios, professional and lay judges at Swedish courts evaluated the persuasiveness of arguments giving a generalized or a specific description of an eyewitness. The generalized version described the witness either as an alcoholintoxicated person or as a child, while the specific version varied both the amount of alcohol consumed (two vs. five glasses of wine) and the child's age (four vs. 12 years). To investigate the effect of legal expertise on argument selection, moreover, law and social science students evaluate the persuasiveness of both argument versions. Though we observed statistically significant prototype effects as well as expertise effects, results were mixed and sometimes ran counter to normative expectation.

We report on experimentally deploying the technique “giving reasons pro et contra” with professional ( N = 239) and lay judges ( N = 372) at Swedish municipal courts. Using a mock legal scenario, participants assessed the relevance of an eyewitness’s previous conviction for his credibility. On average, both groups displayed low degrees of bias. We observed a small positive debiasing effect only for professional judges. Strong evidence was obtained for a relation between profession and relevance-assessment: Lay judges seemed to assign a greater importance to the prior conviction than professional judges did. We discuss challenges for future research, calling other research groups to contribute additional samples.

In addition, comparisons between men and women were made. Participants read a rape vignette in the form of a newspaper article and subsequently attributed victim and perpetrator blame. A 2 (victim’s immigration status) × 2 (perpetrator’s immigration status) × 2 (participant’s immigration status) × 2 (gender of participant) between-subjects design was used. Measures of blame attributions toward the victim and perpetrator were used as dependent variables. The main results showed that participants with an immigrant background and native males attributed significantly more victim and less perpetrator blame. An interaction involving victim and perpetrator immigration status emerged for female participants and were subsequently discussed, as well as suggestions for future research.

This article introduces the term miss rate neglect to capture the systematic failure to properly account for false positives, i.e. the probability of evidence (E) given the hypothesis (H) is false, P(E|~H). Miss rate neglect occurs when decision makers (i) completely disregard the miss rate; (ii) underestimate the importance of differences in the miss rate, or (iii) overlook circumstances that affect the miss rate. We explain the relevance of miss rate neglect for legal decision making, review extant literature, present new experimental work that empirically validates options (ii) and (iii), and propose experimental variations that future research may pursue.
