Show moreWhy can vigilantes count on public support? Why do citizens in certain cases oppose the formal prosecution and punishment of vigilantes? Are such reactions an indication of lacking confidence in the criminal justice system? Or do situational aspects perhaps also play a role? The goal of this dissertation is to explain public support for vigilantism. In two studies, respondents were presented with a fictional case about vigilantism and answered related questions. The findings of both studies show that support for vigilantism cannot be interpreted automatically as a sign that confidence in the criminal justice system is lacking: situational characteristics have an independent influence on support. The results also reveal that support for vigilantism is a complex concept. People are not simply for or against vigilantism; responses to vigilantism are more nuanced. People can for instance feel little empathy for the victim of vigilantism, but at the same time express a desire for punishment of the vigilante. Additionally, a higher level of confidence in the courts and criminal justice system led to less support for vigilantism, while confidence in police did not play a role. Lastly, general support for vigilantism was an important predictor of support for a specific case. Show less

It seems to be a matter of common sense that the level of confidence expressed by a witness can be used as a diagnostic tool to discriminate between accurate and inaccurate memories. Contrary to this general belief, the bulk of empirical evidence collected in laboratory and field experiments over the past 25 years indicates that the relationship between confidence and accuracy is far from perfect. The central focus of this dissertation is on the accuracy of eyewitness memory, and especially on the relationship between accuracy and confidence (i.e., the subjective judgment of accuracy). To enhance the ecological validity of the laboratory studies, we used a method that allowed us to determine accuracy and confidence scores for the recall of details of complex naturalistic events. The first three chapters are experiments from the laboratory testing the effect of repeated retrieval, retention interval and repeated misleading questioning. The fourth chapter is a case study in which real live witnesses of a robbery on a supermarket were interviewed. Our findings show a clear and consistent relationship between confidence judgements and the actual accuracy of memories. With some caution, confidence may be used as a partial indicator of accuracy, especially during the early stages of an investigation. Unfortunately, however, there always remain incorrect items that are given the maximum confidence score. That is the reason why no single witness statement can be accepted as certainly correct, based on confidence alone. Show less
