Racial and ethnic bias in decisions to shoot seen through a stronger lens: experimental results from high-fidelity laboratory simulations

Background

Research on racial bias in the United States includes findings that Americans tend to view blacks as more dangerous than whites. Some have argued that this bias provides a likely explanation for the disproportionate number of ethnic and racial minorities shot by police. One piece of evidence for this proposition comes from experimental work in which research participants push “shoot” or “don’t shoot” buttons when still images of people and objects that may or may not be weapons are presented in rapid succession. These studies have established that participants tend to subconsciously pair black individuals with weapons and white individuals with neutral objects. However, it is not clear from these studies that the subconscious racial bias identified by researchers affects actual decisions to shoot, perhaps because the techniques used to assess the bias-shooting link bear so little resemblance to real-world shootings.

Methods

This paper reports on the results of a novel laboratory experiment designed to overcome this critical limitation by using high-fidelity deadly force judgment and decision-making simulators to assess both subconscious and behavioral bias among 48 research participants, recruited from the general population.

Results

Study results suggest that subconscious associations between race and threat exhibited by participants are not linked to their shooting behavior.

Conclusions

The implications of this finding for understanding how race and ethnicity affect decisions to shoot, and for conducting empirical research on this important topic, are discussed.     

The Impact of Juvenile Court Judge Ethical Orientation on Decision Making

This exploratory study examines the ethical ideologies of a sample of 76 juvenile court judges attending a conference using an Ethical Position Questionnaire. Potential effects of ethical orientation on judicial decision making are identified and discussed. The findings indicate a relatively even distribution of judges across ethical ideologies. The connection between ethical ideology and the prevailing juvenile justice philosophy across jurisdictions, and the importance and complexity of judicial education and training in juvenile justice, are discussed.     

Investigation of hydrogen cyanide generation from the cyanoacrylate fuming process used for latent fingermark detection

Cyanoacrylate fuming is one of the most common techniques employed for the detection of latent fingermarks on non-porous surfaces such as plastic and glass. The technique is generally applied by exposing items of interest to the vapours generated by heating a suitable quantity of commercial cyanoacrylate adhesive. In this study, the potential for highly toxic hydrogen cyanide (HCN) to be generated from the overheating of cyanoacrylate was investigated. Two commercial cyanoacrylate adhesives and two quantitative methods for the determination of HCN were employed: (i) the sodium picrate method; and (ii) the picrate-resorcinol method. (13)C nuclear magnetic resonance (NMR) analysis was used to confirm the presence of cyanide. In addition, the thermal decomposition of cyanoacrylate was studied using simultaneous thermogravimetric and differential thermal analysis (TGA-DTA). It was determined that detectable and quantifiable amounts of HCN were generated from the thermal decomposition of cyanoacrylate monomer and polymer at temperatures as low as 200 °C. Using an optimised picrate-resorcinol method, it was shown that around 10 μg of HCN could be generated from the heating of 1g of cyanoacrylate monomer at 200 °C. For one of the adhesives tested, this increased to above 100 μg of HCN when 1g of cyanoacrylate monomer was heated at 280 °C. Recommendations are provided that, if followed, should ensure that the cyanoacrylate fuming process can be safely applied with minimal risk to the operator.     

Political Institutions,Policymaking, and Policy Stability in Latin America

In some Latin American nations, policy change occurs frequently, while in others it is stable, less prone to shifts with the prevailing political climate or shocks. The conditions under which institutional rules and the powers of key actors influence the capacity for governance vary, and this variation is seldom addressed in the literature. This project examines the effects of the interactions between key policymakers (the executive and the legislature) in Latin America on policy stability across different institutional frameworks. Countries with simultaneously strong executives and weak legislatures are shown to have unstable policy environments, as are countries with a history of unified government and, to a lesser extent, candidate‐centered electoral systems.     

The forensic investigation of propane gas asphyxiation

Two unusual suicides of a 19-year-old white man and a 47-year-old white man, involving propane inhalation and plastic bag suffocation, are described. The special characteristics of propane gas as an asphyxiant agent are discussed, as well as its effect on the human body. The discussion emphasizes the postmortem examination and the collection of samples for toxicologic analysis.     

Citizenship and Res Publica : The Emergence of Republican Rights

A fourth kind of citizens' rights--the republican rights--are being recognized and enforced in the last quarter of the twentieth century, after the civil, political, and social rights have been defined. Republican rights are the rights that every citizen has that the public patrimony, the res publica , is utilized on behalf of the public interest. While civil rights protect citizens against a powerful state, republican rights protect the state against powerful citizens involved in several forms of rent-seeking. Three major types of republican rights are identified: rights to the environment, to the historical patrimony, and to the economic patrimony. The last, in flow terms, corresponds to the state's revenues, which are permanently threatened by businessmen, bureaucrats, and all kinds of special interest groups, sometimes in subtle ways. To identify and contain these threats is a major challenge for modern institutions and law systems.
