Primed and prejudice: the Kurantha-Bothata study

O sistema de peer review é uma ferramenta fundamental nas publicações científicas, cujo objetivo é selecionar os estudos que contribuem para o avanço do conhecimento. No entanto, questionamentos tem surgido acerca de vieses no sistema de peer review. Um exemplo é o estudo "Lost science in the third world" (Gibbs, 1995), que afirma existirem sérios vieses em relação à origem dos pesquisadores. Ainda que haja evidências para suportar esse argumento, nosso conhecimento acerca de vieses no sistema de peer review ainda é limitado, já que poucos estudos controlados podem ser encontrados na literatura. No presente trabalho, foi realizado um exeprimento no qual os sujeitos deveriam avaliar um artigo sem qualquer identificação de autoria, exceto por uma nota de rodapé onde constava o nome da instituição fictícia que financiou a pesquisa. Sob uma condição, o nome da agência financiadora é associado com o continente africano, enquanto na outra condição, o nome da agência é associado ao continente europeu. Os resultados dão indícios de que possa haver um viés relacionado às origens do autor.

Bias in the indexing languages Theorethical approaches about feminine issues

The process of knowledge representation as well as its procedures or tools and its products are not neutral in terms of values; instead they imply moral values. In this context, bias in representation related to prejudice and discrimination, to gender issues, to dicotomic categorization in classification systems or in thesauri and to lack of cultural warrant may arise. Concerning the problem of bias in indexing languages, starting from the initial theoretical reflexions of Brey (1999), Berman (1993), Olson (1998; 2002), Lopez-Huertas Perez & Torres Ramirez (2005), Guimaraes (2006), Hjorland (2008) and Milani et al. (2009), the proposal is to present a preliminary categorization aiming at facilitating the identification of bias concerning feminine issues in indexing languages, to offer a contribution to the theoretical universe of the specific questions of knowledge organization and to present a theme to be discussed by educators and professionals in the areas of cataloging, classification and indexing. If in a society which intends to be politically correct, social attitudes towards stigmatized citizens should be modified, then, the universe of indexing languages, taken as tools of knowledge representation, is a fertile field to sow this reflexion.

The Effects of Living in Segregated vs. Mixed Areas in Northern Ireland: A Simultaneous Analysis of Contact and Threat Effects in the Context of Micro-Level Neighbourhoods

This study examines the consequences of living in segregated and mixed neighbourhoods on ingroup bias and offensive action tendencies, taking into consideration the role of intergroup experiences and perceived threat. Using adult data from a cross-sectional survey in Belfast, Northern Ireland, we tested a model that examined the relationship between living in segregated (N = 396) and mixed (N = 562) neighbourhoods and positive contact, exposure to violence, perceived threat and outgroup orientations. Our results show that living in mixed neighbourhoods was associated with lower ingroup bias and reduced offensive action tendencies. These effects were partially mediated by positive contact. However, our analysis also shows that respondents living in mixed neighbourhoods report higher exposure to political violence and higher perceived threat to physical safety. These findings demonstrate the importance of examining both social experience and threat perceptions when testing the relationship between social environment and prejudice.

Three Experimental Approaches to Measure the Social Context Dependence of Prejudice Communication and Discriminatory Behavior

Empirical research on discrimination is faced with crucial problems stemming from the specific character of its object of study. In democratic societies the communication of prejudices and other forms of discriminatory behavior is considered socially undesirable and depends on situational factors such as whether a situation is considered private or whether a discriminatory consensus can be assumed. Regular surveys thus can only offer a blurred picture of the phenomenon. But also survey experiments intended to decrease the social desirability bias (SDB) so far failed in systematically implementing situational variables. This paper introduces three experimental approaches to improve the study of discrimination and other topics of social (un-)desirability. First, we argue in favor of cognitive context framing in surveys in order to operationalize the salience of situational norms. Second, factorial surveys offer a way to take situational contexts and substitute behavior into account. And third, choice experiments – a rather new method in sociology – offer a more valid method of measuring behavioral characteristics compared to simple items in surveys. All three approaches – which may be combined – are easy to implement in large-scale surveys. Results of empirical studies demonstrate the fruitfulness of each of these approaches.

Racial Bias in Motor Vehicle Searches: Additional Theory and Evidence

Knowles, Persico, and Todd (2001) develop a model of police search and offender behavior. Their model implies that if police are unprejudiced the rate of guilt should not vary across groups. Using data from Interstate 95 in Maryland, they find equal guilt rates for African-Americans and whites and conclude that the data is not consistent with racial prejudice against African-Americans. This paper generalizes the model of Knowles, Persico, and Todd by accounting for the fact that potential offenders are frequently not observed by the police and by including two different levels of offense severity. The paper shows that for African-American males the data is consistent with prejudice against African-American males, no prejudice, and reverse discrimination depending on the form of equilibria that exists in the economy. Additional analyses based on stratification by type of vehicle and time of day were conducted, but did not shed any light on the form of equilibria that best represents the situation in Maryland during the sample period.

Reflections on the statistical analysis of personality and norms in war, peace, and prejudice: Are deviant minorities the problem?

The compelling quality of the Global Change simulation study (Altemeyer, 2003), in which high RWA (right-wing authoritarianism)/high SDO (social dominance orientation) individuals produced poor outcomes for the planet, rests on the inference that the link between high RWA/SDO scores and disaster in the simulation can be generalized to real environmental and social situations. However, we argue that studies of the Person × Situation interaction are biased to overestimate the role of the individual variability. When variables are operationalized, strongly normative items are excluded because they are skewed and kurtotic. This occurs both in the measurement of predictor constructs, such as RWA, and in the outcome constructs, such as prejudice and war. Analyses of normal linear statistics highlight personality variables such as RWA, which produce variance, and overlook the role of norms, which produce invariance. Where both normative and personality forces are operating, as in intergroup contexts, the linear analysis generates statistics for the sample that disproportionately reflect the behavior of the deviant, antinormative minority and direct attention away from the baseline, normative position. The implications of these findings for the link between high RWA and disaster are discussed.

Criticizing groups from the inside and the outside: An identity perspective on the intergroup sensitivity effect

Research on group criticism has demonstrated that criticisms are received less defensively when made by an ingroup member than when made by an outsider (the intergroup sensitivity effect). Three experiments tested the extent to which this effect is driven by social identity concerns or by judgments of how experienced the source of the criticism is. In Experiments I and 2, Australians who criticized Australia (ingroup critics) were met with less defensiveness than were foreigners who criticized Australia (outgroup critics), regardless of the amount of experience the foreigner had with Australia. Furthermore, the effects of speaker type on evaluations were mediated by perceptions of the extent to which the criticisms were intended to be constructive but not by perceptions of experience. Finally, Experiment 3 indicated that although experience does not help outgroup critics, a lack of experience can hurt ingroup critics. Recommendations are provided as to how people can reduce defensiveness when making group criticisms.

Imagined intergroup contact and common ingroup identity:an integrative approach

We conducted two studies involving two different age groups (elementary school children and adults) aimed at integrating imagined contact and common ingroup identity models. In the first study, Italian elementary school children were asked to imagine interacting with an unknown immigrant peer as members of a common group. Results revealed that common ingroup imagined contact, relative to a control condition, improved outgroup helping intentions assessed 1 week and 2 weeks after the intervention. In the second study, common ingroup imagined contact led Italian university students to display higher intentions to have contact with immigrants compared to control conditions. In conclusion, results from both studies demonstrate that imagining an intergroup interaction as members of the same group strengthens the effects of imagined contact. These findings point to the importance of combining the common ingroup identity model and the imagined contact theory in order to increase the potentiality of prejudice reduction interventions.

Subliminal influence on generosity

We experimentally subliminally prime subjects prior to charity donation decisions by showing words that have connotations of pro-social values for a very brief time (17ms). Our main fnding is that, compared to a baseline condition, the pro-social prime increases donations by approximately 10-17 percent among subjects with strong pro-social preferences (universalism values). We find a similar effect when interacting the prime with the Big 5 personality characteristic of agreeableness. We furthermore introduce a novel method for testing for priming, "subliminity". This method reveals that some subjects are capable of recognizing prime words, and the overall results are weaker when we control for this capacity.

Black and Blue: Exploring Racial Bias and Law Enforcement in the Killings of Unarmed Black Male Civilians

In late 2014, a series of highly publicized police killings of unarmed Black male civilians in the United States prompted large-scale social turmoil. In the current review, we dissect the psychological antecedents of these killings and explain how the nature of police work may attract officers with distinct characteristics that may make them especially well-primed for negative interactions with Black male civilians. We use media reports to contextualize the precipitating events of the social unrest as we ground our explanations in theory and empirical research from social psychology and industrial and organizational (I/O) psychology. To isolate some of the key mechanisms at play, we disentangle racial bias (e.g., stereotyping processes) from common characteristics of law enforcement agents (e.g., social dominance orientation), while also addressing the interaction between racial bias and policing. By separating the moving parts of the phenomenon, we provide a more fine-grained analysis of the factors that may have contributed to the killings. In doing so, we endeavor to more effectively identify and develop solutions to eradicate excessive use of force during interactions between “Black” (unarmed Black male civilians) and “Blue” (law enforcement).

Crime and prejudice: The influence of appearance on blame amongst perpetrators and victims

Stereotypes based on characteristics such as age, race, and gender influence opinions in a criminal context. Yet, to date research has largely assessed whether perpetrators, rather than victims, are judged differently. Furthermore, although facial features can be a source of unconscious bias, research has failed to assess whether perceptions based on facial features affect the criminal context. To better understand the relationship between stereotypic facial features and gender, and whether this varies across perpetrators and victims, participants were asked to answer questions about an aggravated assault scenario after viewing an image of a person described as the victim or the alleged perpetrator. Images varied in gender and in presence or absence of tattoos or gothic makeup. Participants sympathized with the victim regardless of gender, but discrepancies were stronger if the victim was female than male. Neutral and tattooed faces were judged more harshly than faces with gothic makeup, regardless of gender.

Der Anti-Bias-Ansatz als Methode politischer Erwachsenenbildung

Vorurteile, Macht und Diskriminierung sind die zentralen Themen des Anti-Bias-Ansatzes, der Diskriminierung auf zwischenmenschlicher, struktureller und gesellschaftlich-kultureller Ebene berücksichtigt. Die eigene Verwobenheit in Machtverhältnisse und damit verbundene Erfahrungen von Diskriminierung und Privilegierung sind dabei der Ausgangspunkt des Lernens. Vision ist eine vorurteilsbewusste, diskriminierungskritische und machtsensible Gesellschaft. Der vorliegende Beitrag stellt den Anti-Bias-Ansatz als Methode politischer Erwachsenenbildung vor. Hierfür werden die (Macht-)Mechanismen der Entstehung, Verinnerlichung und Reproduktion von Vorurteilen und Diskriminierung beleuchtet und wird die Intersektionalität (Überkreuzung) verschiedener Differenzlinien ausgemacht und aufgedeckt. Den Abschluss bildet ein Beispiel konkreter Umsetzung. (DIPF/Orig.)

Estereotipos sobre el envejecimiento según el periodo del desarrollo y el género

Teniendo en cuenta el drástico aumento en Colombia y el mundo de la población adulta mayor la pirámide poblacional se ha invertido. Lo que ha generado que cada vez haya más adultos mayores y la esperanza de vida sea mayor. Motivo por el cual surge la importancia de conocer diversos aspectos del envejecimiento, entre ellos los estereotipos. Adicionalmente hay muy poca investigación relacionada con los estereotipos sobre el envejecimiento según el género y el periodo de desarrollo. Levy (2009) encontró que son los jóvenes quienes tienen más estereotipos negativos sobre el envejecimiento pues estos sienten que la vejez está muy lejos de su realidad actual y no es en una amenaza personal. Por otro lado Bodner, Bergman y Cohen (2012), encontraron que son los hombres quienes tienen más estereotipos negativos sobre el envejecimiento. La presente investigación tuvo como objetivo describir el efecto del periodo del desarrollo y el género en los estereotipos sobre el envejecimiento en 860 adultos colombianos. Se midió la variable de estereotipos sobre el envejecimiento a través del cuestionario de Ramírez y Palacios (2015) y el periodo del desarrollo y el género a través de un cuestionario de datos sociodemograficos. Contrario a lo esperado, los resultados mostraron que no existe relación entre los estereotipos negativos con el género, el periodo del desarrollo, ni en la interacción de estos. En cambio, se encontraron diferencias entre los estereotipos positivos el género y el periodo de desarrollo. Se considera importante continuar realizando investigaciones relacionadas con esta temática pues cada vez son más los adultos mayores y la manera en que nos relacionemos con ellos, va a determinar un mejor proceso de envejecimiento para ellos.

Hubble parameter reconstruction from a principal component analysis: minimizing the bias

Aims. A model-independent reconstruction of the cosmic expansion rate is essential to a robust analysis of cosmological observations. Our goal is to demonstrate that current data are able to provide reasonable constraints on the behavior of the Hubble parameter with redshift, independently of any cosmological model or underlying gravity theory. Methods. Using type Ia supernova data, we show that it is possible to analytically calculate the Fisher matrix components in a Hubble parameter analysis without assumptions about the energy content of the Universe. We used a principal component analysis to reconstruct the Hubble parameter as a linear combination of the Fisher matrix eigenvectors (principal components). To suppress the bias introduced by the high redshift behavior of the components, we considered the value of the Hubble parameter at high redshift as a free parameter. We first tested our procedure using a mock sample of type Ia supernova observations, we then applied it to the real data compiled by the Sloan Digital Sky Survey (SDSS) group. Results. In the mock sample analysis, we demonstrate that it is possible to drastically suppress the bias introduced by the high redshift behavior of the principal components. Applying our procedure to the real data, we show that it allows us to determine the behavior of the Hubble parameter with reasonable uncertainty, without introducing any ad-hoc parameterizations. Beyond that, our reconstruction agrees with completely independent measurements of the Hubble parameter obtained from red-envelope galaxies.
