Recently, research has begun to explore consumer attitudes to the product, revealing a number of barriers and demographic predictors. However, our understanding of the psychological mechanisms that underpin attitudes to cultured meat remains limited. In the current study, we draw on an attitude roots model (Hornsey & Fielding, 2017) to explore a range of psychological mechanisms that may underpin attitudes to cultured meat. In terms of negative attitudes and intentions toward cultured meat, the most powerful predictors were food neophobia, political conservatism, and distrust of food scientists. When it comes to absolute opposition to cultured meat - defined by the unconditional belief that it should never be allowed under any circumstances - the strongest predictors were food and hygiene disgust sensitivity subscales, food neophobia, and conspiratorial ideation. A number of presumed mechanisms held no relationships to cultured meat attitudes, including social dominance orientation, speciesism, and naturalness bias. The null results on naturalness bias are of particular interest given recent research identifying concerns about naturalness as a key barrier to consumer acceptance. These results demonstrate the need for a more nuanced understanding of the psychological mechanisms that contribute to cultured meat attitudes and engagement.

We predict that in holistic cultures-where contradiction, change, and context are emphasized-ideal states of being for the self will be more moderate than in other cultures. In two studies ( Ns = 2,392 and 6,239), we asked this question: If participants could choose their ideal level of happiness, pleasure, freedom, health, self-esteem, longevity, and intelligence, what level would they choose? Consistent with predictions, results showed that maximization was less pronounced in holistic cultures; members of holistic cultures aspired to less happiness, pleasure, freedom, health, self-esteem, longevity, and IQ than did members of other cultures. In contrast, no differences emerged on ideals for society. The studies show that the maximization principle is not a universal aspect of human nature and ...

Using a large representative sample of New Zealanders, we found that minority group members in outgroup dense environments reported lower levels of social dominance orientation (Study 1). In studies 2 and 3, Asian Australian and Black American participants who were surrounded by outgroup members reported lower social dominance orientation. For majority group (White) participants there was no association between social dominance orientation and outgroup density. Study 4 explained the overall pattern: Black Americans surrounded by outgroup members perceived their group to be of lower status in their immediate environment, and through this, reported lower social dominance orientation. This article adds to growing literature on contextual factors that predict social dominance orientation, especially among minority gro...

Many intervention programs work from a deficit model of science communication, presuming that vaccination skeptics lack the ability to access or understand evidence. However, interventions focusing on evidence and the debunking of vaccine-related myths have proven to be either nonproductive or counterproductive. Working from a motivated reasoning perspective, we examine the psychological factors that might motivate people to reject scientific consensus around vaccination. To assist with international generalizability, we examine this question in 24 countries. We sampled 5,323 participants in 24 countries, and measured their antivaccination attitudes. We also measured their belief in conspiracy theories, reactance (the tendency for people to have a low tolerance for impingements on their freedoms), disgust sensitivity toward blood and...

In this review, we explore one possible reason for this cross-cultural difference, that Asian cultures think differently about emotion than do Western cultures and that these different systems of thought help explain why negative affect does not escalate into clinical disorder at the same rate. We review research from multiple disciplines-including cross-cultural psychology, social cognition, clinical psychology, and psychiatry-to make the case that the Eastern holistic principles of contradiction (each experience is associated with its opposite), change (the world exists in a state of constant flux), and context (the interconnectedness of all things) fundamentally shape people's experience of emotions in different cultures. We then review evidence for how these cultural differences influence how successfully people use common emotion regulation strate...

Roughly one third of Americans are skeptical that humans are primarily responsible for climate change; rates of some infectious diseases are climbing in the face of anti-immunization beliefs; and significant numbers of the population worldwide are antievolution creationists. It is easy to assume that resistance to an evidence-based message is a result of ignorance or failure to grasp evidence (the "deficit model" of science communication). But increasingly, theorists understand there are limits to this approach, and that if people are motivated to reject science, then repeating evidence will have little impact. In an effort to create a transtheoretical language for describing these underlying motivations, we introduce the notion of "attitude roots." Attitude roots are the underlying fears, ideologies, worldviews, and identity needs that sustain and motivate specific "surface&...

Little is known, however, about how negative contact with the advantaged predicts collective action among members of disadvantaged groups. With samples of Black and Hispanic Americans, we tested positive and negative contact with White Americans as predictors of self-reported collective action behaviour and future intentions. Across both samples, negative contact with White Americans predicted greater collective action, largely through the mechanisms of perceived discrimination and intergroup anger. Simultaneously, positive contact showed a negative indirect effect on collective action primarily through reduced anger. These findings suggest that negative contact may be a potential driver of social change among racial minorities. Implications of these findings for the contact and collective action literatures are discussed.

For collective apologies, we argue that sincerity takes on a particular meaning: It is a function of the apology's perceived representativeness for the offender group's will or sentiment. Consistent with this notion, when an apologetic (vs. nonapologetic) message was democratically chosen (Study 1) or explicitly endorsed by the majority of the offending outgroup (Study 2), it was considered more sincere and, through this, led to more forgiveness. Furthermore, while disagreement about an apology within the offender group reduced its perceived representativeness and sincerity, this was less so when the dissenters could be subtyped: when disagreement was correlated with an existing subgroup within the offending outgroup (Study 3) and in line with expectations for that subgroup (Study 4). This research shows that victim group members consider intragroup processes within the offending outgroup for attributions of sincerity.

Theoretically, women's numerical strength makes them well-placed to take effective collective action, and millions of women engage in feminist collective action every day. In this article, however, we argue that women also face barriers to engaging in feminist collective action; barriers that are associated with the social construction and experience of what it means to be a woman. Our review synthesizes sexism research under a contemporary collective action framework to clarify our current understanding of the literature and to offer novel theoretical explanations for why women might be discouraged from engaging in feminist collective action. Using the antecedents of collective action identified by van Zomeren, Postmes, and Spears' (2008) meta-analysis, we critically review the sexism literature to argue that women face challenges when it comes to (a) identifying with other women and feminists, (b) perceiving sexism and expressing group-based anger, and (c) recognizing the efficacy of collective action. We then outline a research agenda with a view to investigating ways of overcoming these barriers. (PsycINFO Database Record

A convergence of evidence – including that within the social identity tradition – shows that intragroup differentiation is not incompatible with strong group identity. Indeed, when norms encourage autonomy, dissent, and individual freedom, intragroup differentiation occurs through group commitment, not despite it.

We hypothesized that women's endorsement of a benevolently sexist worldview would be negatively associated with orgasm frequency. Specifically, we predicted that benevolent sexism would be associated with increased perceptions of male sexual selfishness. This perception of men as interested in their own sexual pleasure would then predict decreased willingness to ask a partner for sexual pleasure, which in turn would be associated with less frequent orgasms. We found support for our model across two studies (Study 1: N = 339; Study 2: N = 323). We did not, however, find a direct effect of benevolent sexism on orgasm frequency. We discuss possible additional variables linking benevolent sexism with orgasm frequency, implications, and futu...

Seven studies provide evidence for a "small = trustworthy" heuristic, such that people perceive numerically smaller groups as more benevolent in their character and intentions. As a result of this, individuals in trust-sensitive contexts are more likely to approach and engage with groups that are relatively small than those that are relatively large. We provide evidence for this notion across a range of contexts, including analyses of social categories (Studies 1 and 2), ad hoc collections of individuals (Study 3), interacting panels (Studies 4-6), and generalized, abstract judgments (Study 7). Findings suggest the existence of a general lay theory of group size that may influence how individuals interact with groups.

In a series of experiments, Australians read scenarios in which Australian interests had been harmed by an outgroup. Participants were then told that the outgroup had either apologized or had not apologized for the offense. Although the presence of an apology helped promote perceptions that the outgroup was remorseful, and although participants were more satisfied with an apology than with no apology, the presence of the apology failed to promote forgiveness for the offending group. This was the case regardless of whether the effectiveness of apology was measured cross-sectionally (Experiment 1) or longitudinally (Experiment 2). It was also the case when the apology was accompanied by victims advocating forgiveness (Experiment 3) and was independent of the emotionality of the apology (Experiment 4). In contrast, individuals who apologized for intergroup atrocities were personally forgiven more than those who did not apologize (Experiment 4). Theoretical and applied implications are discussed.

Australian university students evaluated the extent to which various personality traits were more or less applicable to themselves than to other Australian university students in general. They then evaluated the extent to which the same traits were more or less applicable to Australians than to people from other countries in general. As expected, the more participants evaluated themselves as superior to other university students, the more they evaluated Australians as a whole as superior to people from other countries. This link between interpersonal and intergroup superiority biases explained 22.1% of variance in Study I and 33.6% of variance in Study 2. The author interprets the results of the 2 studies as support for fundamental principles of social identity theory: (a) that self-concept consists of not only one's personal self but also the social groups to which one belongs and (b) that people are motivated to view both levels of self in a relatively positive fashion.
