The communication of social stereotypes: the effects of group discussion and information distribution on stereotypic appraisals

Incorporating Social-Marketing Insights Into Prejudice Research: Advancing Theory and Demonstrating Real-World Applications

Prejudice researchers have proposed a number of methods to reduce prejudice, drawing on and, in turn, contributing to our theoretical understanding of prejudice. Despite this progress, relatively few of these methods have been shown to reliably improve intergroup relations in real-world settings, resulting in a gap between our theoretical understanding of prejudice and real-world applications of prejudice-reduction methods. In this article, we suggest that incorporating principles from another field, social marketing, into prejudice research can help address this gap. Specifically, we describe three social-marketing principles and discuss how each could be used by prejudice researchers. Several areas for future research inspired by these principles are discussed. We suggest that a hybrid approach to research that uses both theory-based and problem-based principles can provide additional tools for field practitioners aiming to improve intergroup relations while leading to new advances in social-psychological theory.

Bad Is Stronger Than Good for Stigmatized, but Not Admired Outgroups: Meta-Analytical Tests of Intergroup Valence Asymmetry in Individual-to-Group Generalization Experiments

Theories of risk aversion, epistemic defense, and ingroup enhancement converge in predicting greater impact of negative (vs. positive) experiences with outgroup members on generalized evaluations of stigmatized outgroups. However, they diverge in predictions for admired outgroups. Past tests have focused on negative outgroups using correlational designs without a control group. Consequently, they have not distinguished between alternative explanations or ascertained the direction of causality/generalization, and they have suffered from self-selection biases. These limitations were redressed by a meta-analysis of experimental research on individual-to-group generalization with positive and negative outgroups (59 tests; 3,012 participants). Controlling for modest confounds, the meta-analysis found a generalization advantage of negative experiences for stigmatized outgroups and a generalization advantage of positive experiences for admired outgroups. These results highlight the centrality of valenced expectations about outgroups, consistent with epistemic defense and ingroup enhancement and inconsistent with risk aversion. Implications for positive changes in intergroup dynamics are discussed.

Agent-Based Modeling: A New Approach for Theory Building in Social Psychology

Most social and psychological phenomena occur not as the result of isolated decisions by individuals but rather as the result of repeated interactions between multiple individuals over time. Yet the theory-building and modeling techniques most commonly used in social psychology are less than ideal for understanding such dynamic and interactive processes. This article describes an alternative approach to theory building, agent-based modeling (ABM), which involves simulation of large numbers of autonomous agents that interact with each other and with a simulated environment and the observation of emergent patterns from their interactions. The authors believe that the ABM approach is better able than prevailing approaches in the field, variable-based modeling (VBM) techniques such as causal modeling, to capture types of complex, dynamic, interactive processes so important in the social world. The article elaborates several important contrasts between ABM and VBM and offers specific recommendations for learning more and applying the ABM approach.

Communication and Group Perception: Extending the `Saying is Believing' Effect

The saying-is-believing (SIB) effect occurs when tailoring a message to suit an audience influences a communicator's subsequent memories and impressions about the communication topic. Previous studies were restricted to one-person audiences and individuals as the communication topic. The present studies explored the SIB effect with multiple-person audiences and groups as the communication topic. In Study 1, the SIB effect occurred with a 1-person, but not a 3-person, audience. In Study 2, the SIB effect occurred with a 3-person audience when the audience explicitly validated communicators' messages. These findings demonstrate the generalizability of the SIB effect to group contexts, provide further evidence for a shared reality interpretation of this effect, and suggest a potentially important mechanism underlying stereotype development.

Cultural evolution: interpersonal influence, issue importance, and the development of shared attitudes in college residence halls

This article investigates cultural evolution in four college residence halls. Up to four attitude surveys were completed by 1,252 participants in a semester. Participants' attitudes became more similar to those living closest to them over time as a result of localized interpersonal influence processes. Correlations between attitudes also increased with time as these cultural attributes grew increasingly interdependent. These basic findings support the predictions of dynamic social impact theory. However, these effects were stronger for more important issues even when controlling for discussion. These findings are likely the result of (a) individual-level selective attention to personally important information, (b) greater attitude-behavior consistency for important issues, and/or (c) nonlinear attitude change processes for important issues as suggested by the catastrophe theory of attitudes. These results suggest that intrapsychic processes as well as interpersonal processes contribute to cultural evolution.

Talking nets: a multiagent connectionist approach to communication and trust between individuals

A multiagent connectionist model is proposed that consists of a collection of individual recurrent networks that communicate with each other and, as such, is a network of networks. The individual recurrent networks simulate the process of information uptake, integration, and memorization within individual agents, and the communication of beliefs and opinions between agents is propagated along connections between the individual networks. A crucial aspect in belief updating based on information from other agents is the trust in the information provided. In the model, trust is determined by the consistency with the receiving agents' existing beliefs and results in changes of the connections between individual networks, called trust weights. These weights lead to a selective propagation and thus to the filtering out of less reliable information, and they implement H. P. Grice's (1975) maxims of quality and quantity in communication. The unique contribution of communicative mechanisms beyond intrapersonal processing of individual networks was explored in simulations of key phenomena involving persuasive communication and polarization, lexical acquisition, spreading of stereotypes and rumors, and a lack of sharing unique information in group decisions.

How are stereotypes maintained through communication? The influence of stereotype sharedness

Recent research has suggested that interpersonal communication may be an important source of stereotype maintenance. When communicated through a chain of people, stereotype-relevant information tends to become more stereotypical, thus confirming the stereotypes held by recipients of communication. However, the underlying mechanisms of this phenomenon have yet to be fully determined. This article examines how the socially shared nature of stereotypes interacts with communication processes to maintain stereotypes in communication chains. In 3 experiments, participants communicated a stereotype-relevant story through 4-person chains using the method of serial reproduction. Manipulations included the extent to which communicators believed their audience and other community members shared and endorsed their stereotypes, and also the extent to which they actually shared the stereotypes. The shared nature of stereotypes was found to be a strong contributor to rendering the story more stereotypical in communication. This is discussed in relation to the maintenance of stereotypes through communication.
