Prejudice Reduction: Progress and Challenges.

The past decade has seen rapid growth in research that evaluates methods for reducing prejudice. This essay reviews 418 experiments reported in 309 manuscripts from 2007 to 2019 to assess which approaches work best and why. Our quantitative assessment uses meta-analysis to estimate average effects. Our qualitative assessment calls attention to landmark studies that are noteworthy for sustained interventions, imaginative measurement, and transparency. However, 76% of all studies evaluate light touch interventions, the long-term impact of which remains unclear. The modal intervention uses mentalizing as a salve for prejudice. Although these studies report optimistic conclusions, we identify troubling indications of publication bias that may exaggerate effects. Furthermore, landmark studies often find limited effects, which suggests the need for further theoretical innovation or synergies with other kinds of psychological or structural interventions. We conclude that much research effort is theoretically and empirically ill-suited to provide actionable, evidence-based recommendations for reducing prejudice.

The effect of a savings intervention on women's intimate partner violence victimization: heterogeneous findings from a randomized controlled trial in Colombia.

BACKGROUND: Women's economic empowerment has long been assumed to lead to their social empowerment, but systematic tests of this relationship have only recently begun to appear in the literature. Theory predicts that control over resources, as through a savings account, may increase women's negotiating power and self-efficacy. In this way, "economic empowerment" may lead to "social empowerment," and have related benefits such as helping to reduce risk of intimate partner violence (IPV). The current study tests effects of an economic empowerment intervention on women's social empowerment, IPV victimization, and health. METHODS: We conducted an 18-month randomized controlled trial among 1800 urban poor women in Colombia between 2013 and 2015. The trial tested the impact of a savings account offer bundled with health services (vs. health services alone) on social empowerment outcomes, IPV victimization, and health. RESULTS: The bundled savings treatment did not have average effects on most outcomes, although it produced a small significant increase in financial participation and decrease in symptoms of depression. Treatment effects on perceived norms, decision-making patterns, self-reported IPV victimization, and health depended on whether women's partnerships were free of violence when they entered the trial; specifically, women in nonviolent partnerships at baseline showed more positive effects of the intervention. CONCLUSIONS: Although bundling economic empowerment interventions with support features has been shown to empower poor women, this trial found that a bundled treatment did not on average improve most social and health outcomes of poor women experiencing IPV. TRIAL REGISTRATION: Registered retrospectively, prior to realization of outcomes, 5/29/14: Evidence in Governance and Politics #20140529AA .

Changing climates of conflict: A social network experiment in 56 schools.

Theories of human behavior suggest that individuals attend to the behavior of certain people in their community to understand what is socially normative and adjust their own behavior in response. An experiment tested these theories by randomizing an anticonflict intervention across 56 schools with 24,191 students. After comprehensively measuring every school's social network, randomly selected seed groups of 20-32 students from randomly selected schools were assigned to an intervention that encouraged their public stance against conflict at school. Compared with control schools, disciplinary reports of student conflict at treatment schools were reduced by 25% over 1 year. The effect was stronger when the seed group contained more "social referent" students who, as network measures reveal, attract more student attention. Network analyses of peer-to-peer influence show that social referents spread perceptions of conflict as less socially normative.

A pragmatist philosophy of psychological science and its implications for replication.

A pragmatist philosophy of psychological science offers to the direct replication debate concrete recommendations and novel benefits that are not discussed in Zwaan et al. This philosophy guides our work as field experimentalists interested in behavioral measurement. Furthermore, all psychologists can relate to its ultimate aim set out by William James: to study mental processes that provide explanations for why people behave as they do in the world.

The Effect of a Supreme Court Decision Regarding Gay Marriage on Social Norms and Personal Attitudes.

We propose that institutions such as the U.S. Supreme Court can lead individuals to update their perceptions of social norms, in contrast to the mixed evidence on whether institutions shape individuals' personal opinions. We studied reactions to the June 2015 U.S. Supreme Court ruling in favor of same-sex marriage. In a controlled experimental setting, we found that a favorable ruling, when presented as likely, shifted perceived norms and personal attitudes toward increased support for gay marriage and gay people. Next, a five-wave longitudinal time-series study using a sample of 1,063 people found an increase in perceived social norms supporting gay marriage after the ruling but no change in personal attitudes. This pattern was replicated in a separate between-subjects data set. These findings provide the first experimental evidence that an institutional decision can change perceptions of social norms, which have been shown to guide behavior, even when individual opinions are unchanged.

Effects of a US Supreme Court ruling to restrict abortion rights.

Previous research focused on popular US Supreme Court rulings expanding rights; however, less is known about rulings running against prevailing public opinion and restricting rights. We examine the impact of the Dobbs v. Jackson Women's Health Organization opinion, which overturned Roe v. Wade's (1973) constitutional protection of abortion rights. A three-wave survey panel (5,489 interviews) conducted before the leak of the drafted Dobbs opinion, after the leak, and after the official opinion release, and cross-sectional data from these three time points (10,107 interviews) show that the ruling directly influenced views about the constitutional legality of abortion and fetal viability. However, personal opinions were not directly influenced and perceived social norms shifted away from the ruling, meaning that individuals perceived greater public support for abortion. We argue that extensive coverage of opposition to overturning Roe v. Wade supported this shift. Dobbs v. Jackson Women's Health Organization also caused large changes, polarized by party identification, in opinions about the Supreme Court.

Preventing Sexual Violence: A Behavioral Problem Without a Behaviorally Informed Solution.

What solutions can we find in the research literature for preventing sexual violence, and what psychological theories have guided these efforts? We gather all primary prevention efforts to reduce sexual violence from 1985 to 2018 and provide a bird's-eye view of the literature. We first review predominant theoretical approaches to sexual-violence perpetration prevention by highlighting three interventions that exemplify the zeitgeist of primary prevention efforts at various points during this time period. We find a throughline in primary prevention interventions: They aim to change attitudes, beliefs, and knowledge (i.e., ideas) to reduce sexual-violence perpetration and victimization. Our meta-analysis of these studies tests the efficacy of this approach directly and finds that although many interventions are successful at changing ideas, behavior change does not follow. There is little to no relationship between changing attitudes, beliefs, and knowledge and reducing victimization or perpetration. We also observe trends over time, including a shift from targeting a reduction in perpetration to targeting an increase in bystander intervention. We conclude by highlighting promising new strategies for measuring victimization and perpetration and calling for interventions that are informed by theories of behavior change and that center sexually violent behavior as the key outcome of interest.

Survey of open science practices and attitudes in the social sciences.

Open science practices such as posting data or code and pre-registering analyses are increasingly prescribed and debated in the applied sciences, but the actual popularity and lifetime usage of these practices remain unknown. This study provides an assessment of attitudes toward, use of, and perceived norms regarding open science practices from a sample of authors published in top-10 (most-cited) journals and PhD students in top-20 ranked North American departments from four major social science disciplines: economics, political science, psychology, and sociology. We observe largely favorable private attitudes toward widespread lifetime usage (meaning that a researcher has used a particular practice at least once) of open science practices. As of 2020, nearly 90% of scholars had ever used at least one such practice. Support for posting data or code online is higher (88% overall support and nearly at the ceiling in some fields) than support for pre-registration (58% overall). With respect to norms, there is evidence that the scholars in our sample appear to underestimate the use of open science practices in their field. We also document that the reported lifetime prevalence of open science practices increased from 49% in 2010 to 87% a decade later.

The dominance of the individual in intergroup relations research: understanding social change requires psychological theories of collective and structural phenomena.

Dixon et al. suggest that the psychological literature on intergroup relations should shift from theorizing "prejudice reduction" to "social change." A focus on social change exposes the importance of psychological theories involving collective phenomena like social norms and institutions. Individuals' attitudes and emotions may follow, rather than cause, changes in social norms and institutional arrangements.

A Behavioral-Science Framework for Understanding College Campus Sexual Assault.

We propose a behavioral-science approach to sexual assault on college campuses. In this framework, people commit assault when aspects of the immediate situation trigger certain psychological states. No set of mental processes or situational configurations is a precise predictor of assault. Instead, the interaction between mental processes and situational configurations predicts when sexual assault is more or less likely to occur. We begin with an illustrative story to show how a behavioral-science approach is relevant to sexual assault. Next, we map out a framework that suggests how behavioral theories of situations and mental processes have been or could be used to describe, predict, and develop ideas for the reduction of sexual assault. Relevant situational configurations include geographical configurations, local situational and informational cues, and situation-based power. Theories of mental processes include person perception, social norms, moral reasoning, and goals. Our framework can be used to demonstrate how "good" people can commit assault and how individuals can and will refrain from assault within institutions with a "bad" record. Compared with previous theories of sexual assault, a behavioral-science framework offers unique understanding and generative methods for addressing sexual assault on college campuses.

The Future of Women in Psychological Science.

There has been extensive discussion about gender gaps in representation and career advancement in the sciences. However, psychological science itself has yet to be the focus of discussion or systematic review, despite our field's investment in questions of equity, status, well-being, gender bias, and gender disparities. In the present article, we consider 10 topics relevant for women's career advancement in psychological science. We focus on issues that have been the subject of empirical study, discuss relevant evidence within and outside of psychological science, and draw on established psychological theory and social-science research to begin to chart a path forward. We hope that better understanding of these issues within the field will shed light on areas of existing gender gaps in the discipline and areas where positive change has happened, and spark conversation within our field about how to create lasting change to mitigate remaining gender differences in psychological science.

Engineering social change using social norms: lessons from the study of collective action.

Behavioral interventions have embraced social norms as information that can be communicated in simple messages to motivate behavior change. This article argues for the value and necessity of recognizing that social-norm interventions are grounded in group processes. This approach has three major benefits that more than offset the costs of its greater theoretical and practical complexity. One, it improves the effectiveness of existing interventions, including those that target the normative beliefs of individuals. Two, it opens up new intervention strategies that broaden the range of mechanisms used to change behavior. Three, it connects research on social-norm interventions with theories and research on rallies, rebellions, riots, and other forms of collective action.

Participatory practices at work change attitudes and behavior toward societal authority and justice.

Generalized attitudes toward authority and justice are often conceptualized as individual differences that are resistant to enduring change. However, across two field experiments with Chinese factory workers and American university staff, small adjustments to people's experience of participation in the workplace shifted these attitudes one month later. Both experiments randomly assigned work groups to a 20-minute participatory meeting once per week for six weeks, in which the supervisor stepped aside and workers discussed problems, ideas, and goals regarding their work (vs. a status quo meeting). Across 97 work groups and 1,924 workers, participatory meetings led workers to be less authoritarian and more critical about societal authority and justice, and to be more willing to participate in political, social, and familial decision-making. These findings provide rare experimental evidence of the theoretical predictions regarding participatory democracy: that local participatory experiences can influence broader democratic attitudes and empowerment.

Reducing intergroup prejudice and conflict using the media: a field experiment in Rwanda.

Can the media reduce intergroup prejudice and conflict? Despite the high stakes of this question, understanding of the mass media's role in shaping prejudiced beliefs, norms, and behavior is limited. A yearlong field experiment in Rwanda tested the impact of a radio soap opera featuring messages about reducing intergroup prejudice, violence, and trauma in 2 fictional Rwandan communities. Compared with a control group who listened to a health radio soap opera, listeners' perceptions of social norms and their behaviors changed with respect to intermarriage, open dissent, trust, empathy, cooperation, and trauma healing. However, the radio program did little to change listeners' personal beliefs. Group discussion and emotion were implicated in the process of media influence. Taken together, the results point to an integrated model of behavioral prejudice and conflict reduction that prioritizes the communication of social norms over changes in personal beliefs.

What's in a norm? Sources and processes of norm change.

This reply to the commentary by E. Staub and L. A. Pearlman (2009) revisits the field experimental results of E. L. Paluck (2009). It introduces further evidence and theoretical elaboration supporting Paluck's conclusion that exposure to a reconciliation-themed radio soap opera changed perceptions of social norms and behaviors, not beliefs. Experimental and longitudinal survey evidence reinforces the finding that the radio program affected socially shared perceptions of typical or prescribed behavior-that is, social norms. Specifically, measurements of perceptions of social norms called into question by Staub and Pearlman are shown to correlate with perceptions of public opinion and public, not private, behaviors. Although measurement issues and the mechanisms of the radio program's influence merit further testing, theory and evidence point to social interactions and emotional engagement, not individual education, as the likely mechanisms of change. The present exchange makes salient what is at stake in this debate: a model of change based on learning and personal beliefs versus a model based on group influence and social norms. These theoretical models recommend very different strategies for prejudice and conflict reduction. Future field experiments should attempt to adjudicate between these models by testing relevant policies in real-world settings.

Motivating the adoption of new community-minded behaviors: An empirical test in Nigeria.

Social scientists have long sought to explain why people donate resources for the good of a community. Less attention has been paid to the difficult task of motivating the first adopters of these important behaviors. In a field experiment in Nigeria, we tested two campaigns that encouraged people to try reporting corruption by text message. Psychological theories about how to shift perceived norms and how to reduce barriers to action drove the design of each campaign. The first, a film featuring actors reporting corruption, and the second, a mass text message reducing the effort required to report, caused a total of 1181 people in 106 communities to text, including 241 people who sent concrete corruption reports. Psychological theories of social norms and behavior change can illuminate the early stages of the evolution of cooperation and collective action, when adoption is still relatively rare.

Ignoring alarming news brings indifference: Learning about the world and the self.

The broadcast of media reports about moral crises such as famine can subtly depress rather than activate moral concern. Whereas much research has examined the effects of media reports that people attend to, social psychological analysis suggests that what goes unattended can also have an impact. We test the idea that when vivid news accounts of human suffering are broadcast in the background but ignored, people infer from their choice to ignore these accounts that they care less about the issue, compared to those who pay attention and even to those who were not exposed. Consistent with research on self-perception and attribution, three experiments demonstrate that participants who were nudged to distract themselves in front of a television news program about famine in Niger (Study 1), or to skip an online promotional video for the Niger famine program (Study 2), or who chose to ignore the famine in Niger television program in more naturalistic settings (Study 3) all assigned lower importance to poverty and to hunger reduction compared to participants who watched with no distraction or opportunity to skip the program, or to those who did not watch at all.

Does Product Placement Change Television Viewers' Social Behavior?

To what extent are television viewers affected by the behaviors and decisions they see modeled by characters in television soap operas? Collaborating with scriptwriters for three prime-time nationally-broadcast Spanish-language telenovelas, we embedded scenes about topics such as drunk driving or saving money at randomly assigned periods during the broadcast season. Outcomes were measured unobtrusively by aggregate city- and nation-wide time series, such as the number of Hispanic motorists arrested daily for drunk driving or the number of accounts opened in banks located in Hispanic neighborhoods. Results indicate that while two of the treatment effects are statistically significant, none are substantively large or long-lasting. Actions that could be taken during the immediate viewing session, like online searching, and those that were relatively more integrated into the telenovela storyline, specifically reducing cholesterol, were briefly affected, but not behaviors requiring sustained efforts, like opening a bank account or registering to vote.

The contingent smile: a meta-analysis of sex differences in smiling.

The authors present a meta-analysis of sex differences in smiling based on 448 effect sizes derivedfrom 162 research reports. There was a statistically significant tendency for women and adolescent girls to smile more than men and adolescent boys (d = 0.41). The authors hypothesized that sex differences in smiling would be larger when concerns about gender-appropriate behavior were made more conspicuous, situational constraints were absent or ambiguous, or emotion (especially negative) was salient. It was also predicted that the size of the sex difference in smiling would vary by culture and age. Moderator analysis supported these predictions. Although men tend to smile less than women, the degree to which this is so is contingent on rules and roles.
