ItemThe many roles of dehumanization in genocide(Oxford University Press, 2019-12-09)How do otherwise ordinary people become perpetrators of genocide? Why are groups targeted for mass killing? How do groups justify these terrible acts? While there are no easy answers to these questions, social psychologists are especially well positioned to contribute to our understanding of genocide and mass killing. With research targeting key questions -such as how negative impressions of outgroups develop and how social influence can lead people to violate their moral principles and other norms - social psychologists have much to teach us about why groups of people attempt to exterminate other groups, why people participate in such atrocious projects, and how they live with themselves afterwards. By bringing together research previously available only to readers of academic journals, this volume sheds crucial light on human behavior at the extremes and in doing so, helps us take one more step towards preventing future tragedies.

ItemIntergroup metaphors(Peter Lang, 2016)Intergroup metaphors represent human groups as nonhuman entities, such as animals, objects, plants, or forces of nature. These metaphors are abundant, diverse in meanings, and frequently but not invariably derogatory. Intergroup metaphors may be explicitly represented in language or implicitly represented as nonconscious mental associations. Research and theory on dehumanization offer a useful perspective on these metaphors, and show that likening outgroups to animals is a particularly common phenomenon. Frequently, groups are metaphorically compared to disgusting or degrading animals during times of conflict, but people also tend to view members of outgroups as subtly more animal-like or primitive than their own group even in the absence of conflict. Depending on the use of intergroup metaphors in the contexts of race, gender, social class, immigration, mental illness, and terrorism, intergroup metaphors can have damaging consequences for intergroup relations. Metaphors that represent some people as subhuman entities can diminish empathy and compassion for their suffering. Metaphors that represent certain groups as bestial or diabolical can enable violence, including support for harsh treatment by the state. Some metaphors not only promote violence and discrimination but also help people to legitimize violent behavior and injustice after the fact. Metaphors therefore offer an intriguing insight into the nature of intergroup relations, and how these relations are colored not only by positive or negative attitudes but also by dehumanizing perceptions.

ItemThe Origins of Lay Theories: The Case of Essentialist Beliefs(Springer International Publishing, 2017-07-15)This chapter explores the origins of lay theories, with a focus on theories associated with the concept of psychological essentialism such as Dweckian entity theories. I argue that the origins of essentialist lay theories can be approached from cognitive, developmental, cultural, and social perspectives. Cognitively, these theories appear to arise from deep-seated and possibly innate ontological assumptions and mental shortcuts, such as the proposed “inherence heuristic.” Developmentally, they appear to be promoted by particular kinds of language use (e.g., generics) and particular forms of communication by caregivers. The content of essentialist lay theories derives in part from idioms that circulate within a particular culture, making culture an important dimension of any account of theory origins. Finally, essentialist theories are promoted by certain social arrangements, including motivated maintenance of social hierarchies. A full account of the neglected issue of where lay theories come from requires an appreciation of these diverse factors.

ItemSemantic changes in harm-related concepts in English(Language Science Press, 2021-06-29)The chapter investigates semantic changes in core concepts of psychology, specifically focusing on those related to harm. Haslam (2016) hypothesized that many psychological concepts associated with harm (i.e., forms of psychological disturbance, threat, and maltreatment) have undergone semantic broadening in the past half-century in association with cultural shifts and social change. The implications of this “concept creep” hypothesis have been previously explored by prominent social, political, and legal thinkers (Levari et al. 2018, Lukianoff & Haidt 2019, Pinker 2018, Sunstein 2018), but its linguistic dimension has received little empirical attention. Here we apply computational models in order to address the concept creep hypothesis. We start with a description of a typology of semantic shifts and provide a summary of computational methods for automatic detection of the most common changes (broadening, narrowing, hyperbole, and litotes) and utilise those to evaluate core harm-related concepts such as ‘trauma’, ‘harassment’, and ‘bullying’ on a new corpus of psychology literature extending from 1970 to 2017. Our results confirm the initial hypothesis and are in line with earlier studies: most concepts became broader and milder over the last few decades. We then continue with a more detailed study in order to understand how exactly the concepts changed, and to do so employ and evaluate different types of semantic representations. Finally, we additionally train the models on a general domain corpus in order to investigate whether the broadening of harm-related concepts also applies to society at large, rather than only to the academic discourse of psychology. Haslam’s influential account of concept creep (Haslam 2016) proposes that broadened concepts of harm disseminate from academic language into wider public use. This final analysis enables a direct test of that conjecture, including comparative analysis of the extent and timing of historical semantic changes across the two corpora.
