Justifying violence: legitimacy, ideology and public support for police use of force

Under what conditions do people support police use of force? In this paper we assess some of the empirical links between police legitimacy, political ideology (right-wing authoritarianism and social dominance orientation), and support for ‘reasonable’ use of force (e.g. an officer striking a citizen in self-defence) and ‘excessive’ use of force (e.g. an officer using violence to arrest an unarmed person who is not offering violent resistance). Analyzing data from an online survey with US participants (n=186) we find that legitimacy is a positive predictor of reasonable but not excessive police use of force, and that political ideology predicts support for excessive but not reasonable use of force. We conclude with the idea that legitimacy places normative constraints around police power. On the one hand, legitimacy is associated with increased support for the use of force, but only when violence is bounded within certain acceptable limits. On the other hand, excessive use of force seems to require an extra-legal justification that is – at least in our analysis – partly ideological. Our findings open up a new direction of research in what is currently a rather sparse psychological literature on the ability of legitimacy to ‘tame’ coercive power

Authority and punishment: on the ideological basis of punitive attitudes towards criminals

Why do people support tough sentencing of criminal offenders? Three explanations dominate the literature. The first is an instrumental perspective: people are concerned about becoming a victim of crime and they look to punishment to reduce future harm. The second is a relational perspective: people are concerned about community breakdown, and they support punishment to restore moral boundaries. The third is a psychological model based on ideological preferences: people desire conformity and authority in society, and they look to institutions to punish transgressions that threaten collective security. Building on the work of Tyler & Boeckmann (1997), two studies of London citizens (n1=13,929, n2=283) suggest a way of integrating these three perspectives. We show that right-wing authoritarianism predicts both the extent to which people worry about social threats and the extent to which they support harsh punitive measures. Bridging research from political psychology and criminology, we conclude with the idea that popular punitive sentiment is grounded in an uncritical submission to authorities, an adherence to conservative moral values, and consonant concerns about collective security and cohesion

Influence of Multiple Traumatic Event Types on Mental Health Outcomes: Does Count Matter?

The experience of potentially traumatizing events (PTEs) may be associated with conflicting outcomes: individuals may experience greater psychological distress (dose-response theory), or individuals may become more resilient against repeated PTEs (stress-inoculation theory). With limited empirical data comparing these theories, we examined the relationships between the count of lifetime PTE types and psychological outcomes [posttraumatic stress disorder (PTSD), depression, impaired distress tolerance] using linear and quadratic regressions. A linear relationship would support the dose-response theory, and a quadratic relationship would support the stress-inoculation theory. We also explored whether there was a threshold number of PTE types fostering resiliency before an increase of distressing outcomes. The sample included 123 (68.30% female) treatment-seeking patients at a community mental health center participating in a larger study (Contractor et al. in Psychiatry Research, 252, 252215–252222, 2017). Linear regression results indicated number of PTE types significantly predicted increasing PTSD and depression severity and distress tolerance difficulties. Quadratic regression model results were not significant. ROC analyses indicated exposure to at least 3.5 PTE types predicted PTSD with moderate accuracy. In conclusion, the dose-response theory was supported, with results indicating there may be a threshold count of lifetime PTE types (\u3e 3) influencing traumatic stress outcomes

On the justification of intergroup violence: The roles of procedural justice, police legitimacy and group identity in attitudes towards violence among indigenous people

Objective Why do people justify intergroup violence? In this paper we examine attitudes towards violence perpetrated by indigenous activists to claim for rights and violence by pólice officers against indigenous people. We assess the role that perceived pólice legitimacy, procedurally just policing towards the indigenous minority group and group identity play in the justification of intergroup violence. Method We present findings from two surveys (Study 1, n=1493, Study 2, n=198) and an experiment (Study 3, n=76) conducted among indigenous people in Chile. Studies 1 and 2 measure perceptions of police procedural justice towards indigenous people. Study 3 manipulates the fairness with which police officers treat indigenous people. Effects of procedural justice on police legitimacy (Studies 2 and 3) and attitudes towards violence for social change and social control (Studies 1-3) are analyzed. Result Higher perceptions of procedurally just policing towards indigenous people predict more support for police violence and less support for violence perpetrated by indigenous activists. These effects are mediated by perceived police legitimacy and moderated by identification with the minority group. Among people who identify strongly with their indigenous group, perceiving high procedural justice predicts greater police legitimacy, greater support for police violence, and lesser support for violence perpetrated by indigenous activists

Do closed survey questions over-estimate public perceptions of food risks?

In this paper we show that the widely accepted methodology for the assessment of risk perception – Likert type survey questions featuring a set of risks with fixed response alternatives measuring the extent of worry or concern – may over-estimate food risk perception. Using a European representative sample survey (n=26,961) that included an open-ended question asking about problems and risks with food and eating, followed by a battery of closed questions assessing food risk perception we find a similar ranking of perceived food risks across the two methods. Across Europe the five priority concerns are chronic food related illness; food origins and quality; acute food related illness; chemical contamination, and adulteration of food. However, the discrepancies between mentioning a risk in the open ended question and the expression of worry about risks in the closed question are substantial. Of those who did not mention a specific risk category in the open question, between 60% and 83% (depending on risk category) expressed worry in the closed question. This parallels previous research on the fear of crime, showing that survey responses lead to greatly inflated estimates of the public’s fear of crime than is evidenced by qualitative questioning. It is also consistent with evidence from research on cognitive aspects of survey methodology suggesting that survey questions may frame the respondent’s thinking about an issue. We conclude with recommendations for the use of branched questions in the quantitative elicitation of public perceptions of risk

Sex-related differences in risk factors, type of treatment received and outcomes in patients with atrial fibrillation and acute stroke: Results from the RAF-study (Early Recurrence and Cerebral Bleeding in Patients with Acute Ischemic Stroke and Atrial Fibrillation)

Introduction: Atrial fibrillation is an independent risk factor of thromboembolism. Women with atrial fibrillation are at a higher overall risk for stroke compared to men with atrial fibrillation. The aim of this study was to evaluate for sex differences in patients with acute stroke and atrial fibrillation, regarding risk factors, treatments received and outcomes. Methods Data were analyzed from the “Recurrence and Cerebral Bleeding in Patients with Acute Ischemic Stroke and Atrial Fibrillation” (RAF-study), a prospective, multicenter, international study including only patients with acute stroke and atrial fibrillation. Patients were followed up for 90 days. Disability was measured by the modified Rankin Scale (0–2 favorable outcome, 3–6 unfavorable outcome). Results: Of the 1029 patients enrolled, 561 were women (54.5%) (p < 0.001) and younger (p < 0.001) compared to men. In patients with known atrial fibrillation, women were less likely to receive oral anticoagulants before index stroke (p = 0.026) and were less likely to receive anticoagulants after stroke (71.3% versus 78.4%, p = 0.01). There was no observed sex difference regarding the time of starting anticoagulant therapy between the two groups (6.4 ± 11.7 days for men versus 6.5 ± 12.4 days for women, p = 0.902). Men presented with more severe strokes at onset (mean NIHSS 9.2 ± 6.9 versus 8.1 ± 7.5, p < 0.001). Within 90 days, 46 (8.2%) recurrent ischemic events (stroke/TIA/systemic embolism) and 19 (3.4%) symptomatic cerebral bleedings were found in women compared to 30 (6.4%) and 18 (3.8%) in men (p = 0.28 and p = 0.74). At 90 days, 57.7% of women were disabled or deceased, compared to 41.1% of the men (p < 0.001). Multivariate analysis did not confirm this significance. Conclusions: Women with atrial fibrillation were less likely to receive oral anticoagulants prior to and after stroke compared to men with atrial fibrillation, and when stroke occurred, regardless of the fact that in our study women were younger and with less severe stroke, outcomes did not differ between the sexes

Genetic Evidence for the Association between the Early Growth Response 3 (EGR3) Gene and Schizophrenia

Recently, two genome scan meta-analysis studies have found strong evidence for the association of loci on chromosome 8p with schizophrenia. The early growth response 3 (EGR3) gene located in chromosome 8p21.3 was also found to be involved in the etiology of schizophrenia. However, subsequent studies failed to replicate this finding. To investigate the genetic role of EGR3 in Chinese patients, we genotyped four SNPs (average interval ∼2.3 kb) in the chromosome region of EGR3 in 470 Chinese schizophrenia patients and 480 healthy control subjects. The SNP rs35201266 (located in intron 1 of EGR3) showed significant differences between cases and controls in both genotype frequency distribution (P = 0.016) and allele frequency distribution (P = 0.009). Analysis of the haplotype rs35201266-rs3750192 provided significant evidence for association with schizophrenia (P = 0.0012); a significant difference was found for the common haplotype AG (P = 0.0005). Furthermore, significant associations were also found in several other two-, and three-SNP tests of haplotype analyses. The meta-analysis revealed a statistically significant association between rs35201266 and schizophrenia (P = 0.0001). In summary, our study supports the association of EGR3 with schizophrenia in our Han Chinese sample, and further functional exploration of the EGR3 gene will contribute to the molecular basis for the complex network underlying schizophrenia pathogenesis
