Savouring morality. Moral satisfaction renders food of ethical origin subjectively tastier

Boyka Bratanova; Christine-Melanie Vauclair; Nicolas Kervyn; Sandy Schumann; Robert E. Wood; Olivier Klein

Past research has shown that the experience of taste can be influenced by a range of external cues, especially when they concern foods quality. The present research examined whether foods ethicality - a cue typically unrelated to quality - can also influence taste. We hypothesised that moral satisfaction with the consumption of ethical food would positively influence taste expectations, which in turn will enhance the actual taste experience. This enhanced taste experience was further hypothesised to act as a possible reward mechanism reinforcing the purchase of ethical food. The resulting ethical food → moral satisfaction  → enhanced taste expectations and experience → stronger intentions to buy/willingness to pay model was validated across four studies: one large scale international survey (Study 1) and three experimental studies involving actual food consumption of different type of ethical origin - organic (Study 2), fair trade (Study 3a) and locally produced (Study 3b). Furthermore, endorsement of values relevant to the foods ethical origin moderated the effect of foods origin on moral satisfaction, suggesting that the model is primarily supported for people who endorse these values.

Poverty, inequality, and increased consumption of high calorie food: Experimental evidence for a causal link

Boyka Bratanova; Steve Loughnan; Olivier Klein; Almudena Claassen; Robert E. Wood

Rising obesity represents a serious, global problem. It is now well established that obesity is associated with poverty and wealth inequality, suggesting that these factors may promote caloric intake. Whereas previous work has examined these links from an epidemiological perspective, the current paper examined them experimentally. In Study 1 we found that people experimentally induced to view themselves as poor (v. wealthy) exhibited increased calorie intake. In Study 2, participants who believed that they were poorer or wealthier than their interaction partners exhibited higher levels of anxiety compared to those in an equal partners condition; this anxiety in turn led to increased calorie consumption for people who had a strong need to belong. The findings provide causal evidence for the poverty-intake and inequality-intake links. Further, we identify social anxiety and a strong need to belong as important social psychological factors linking inequality to increased calorie intake.

Income inequality and fear of crime across the European region

Christin-Melanie Vauclair; Boyka Bratanova

This paper aims to take a holistic approach to studying fear of crime by testing predictors at multiple levels of analyses. Data from the European Social Survey (N = 56,752 from 29 countries) were used to test and extend the Income Inequality and Sense of Vulnerability Hypotheses. The findings confirm that (1) individuals in societies with greater income inequalities are more fearful of crime, and (2) older or disabled people as well as women report greater fear of crime. Contrary to the hypotheses, ethnic majority and not ethnic minority members report greater fear of crime, if they reside in high income inequality countries. It is further demonstrated that fear of crime explains the inverse association between income inequality and subjective well-being in this particular subsample.

Confirmatory processes in attitude transmission: the role of shared reality

Arthur A. Stukas; Boyka Bratanova; Kim Peters; Yoshihisa Kashima; Ruth Beatson

In social communication, do message senders’ expectations about message recipients play any role in the construction of social stereotypes? In particular, can senders’ expectations about recipients’ attitudes toward social groups initiate a confirmatory process whereby both senders and recipients come to hold the expected attitudes when there is no basis for them? In Study 1 senders composed messages biased in the direction of randomly assigned expectations about a recipients attitudes toward students living on campus by selectively modifying items of gossip. Senders also subsequently reported attitudes biased in the direction of their messages. In Study 2 yoked participants read the original messages and formed attitudes that reflected the biased content of the original messages. Importantly, this confirmatory effect of attitude transmission was heightened by receivers’ perceptions that shared reality was created with the sender.

The rich get richer, the poor get even: Perceived socioeconomic position influences micro-social distributions of wealth.

Boyka Bratanova; Stephen Loughnan; Olivier Klein; Robert E. Wood

Economic inequality has a robust negative effect on a range of important societal outcomes, including health, wellbeing, and education. Yet, it remains insufficiently understood why, how, and by whom unequal systems tend to be perpetuated. In two studies we examine whether psychological mindsets adopted by the wealthy and the poor in their micro-social transactions act to perpetuate or challenge inequality. We hypothesized that occupying a wealthier socioeconomic position promotes the pursuit of self-interest and contributes to inequality maintenance; poorer socioeconomic position, on the other hand, should promote the pursuit of fairness and equality restoration. In Study 1, participants completed an ultimatum game as proposers after being primed to believe they are wealthier or poorer, offering money to either poor or wealthy responders. As expected, the wealthy pursued their self-interest and the net effect of this behavior contributes to the maintenance of inequality. Conversely, the poor pursued fairness and the net effect of this behavior challenges inequality. In Study 2, participants were responders deciding whether to accept or reject unfair distributions. Compared to the wealthier, the poorer challenged inequality by rejecting unequal offers. The links between micro-social processes and macro-societal inequality are discussed.

The “Saying Is Repeating” Effect: Dyadic Communication Can Generate Cultural Stereotypes

Boyka Bratanova; Yoshihisa Kashima

It has been long established that interpersonal communication underpins the existence of cultural stereotypes. However, research has either examined the formation of new or the maintenance of existing stereotypes. In a series of three studies, the present research bridges the gap between these phases by showing that newly formed stereotypes can spread through repeated dyadic communication with others. The stereotypic representation arose due to the audience tuning in to communication to a first audience. Further transmission to two types of subsequent audiences was simulated: a newcomer and an old-timer with an unknown attitude towards the target. A “saying-is-repeating” effect was obtained: the stereotypic representation was invariably transmitted to the newcomer, regardless of whether communicators personally believed in the bias; perceived group-level consensus moderated its transmission to the old-timer. These findings demonstrate that once a stereotypic representation is formed, it is likely to spread in a community and potentially become a cultural stereotype.

Tasteful brands: products of brands perceived to be warm and competent taste subjectively better

Boyka Bratanova; Nikolas Kervyn; Olivier Klein

Using survey and experimental data, the present research examines the effect of brand perception on experienced taste. The content of brand perception can be organized along the two social perception dimensions of warmth and competence. We use these two dimensions to systematically investigate the influence of brand perception on experienced taste and consumer behavior toward food products. The brand’s perceived warmth and competence independently influenced taste, both when it was measured as a belief and as an embodied experience following consumption. Taste mediated the link between brand’s warmth and competence perceptions and three consumer behavioral tendencies crucial for the marketing success of brands: buying intentions, brand loyalty, and support for the brand.

Social transmission and shared reality in cultural dynamics

Yoshihisa Kashima; Boyka Bratanova; Kim Peters

Micro cultural dynamics are concerned with the mechanisms of transmission, retention, and modification of cultural information in social networks. When interacting individuals mutually recognize that they share psychological reactions to given cultural information, it may be grounded as an aspect of their shared reality under specifiable conditions. The interpretation of cultural information as socially verified shared reality provides a basis for further dissemination of the information and coordinated social action. We review the recent literature that supports this general contention, while highlighting the role of emotion-a somewhat under-recognized aspect of shared reality research-and emphasizing the mediating role of cultural dynamics in the mutual constitution of social reality and shared reality.

A systematic review of psychosocial explanations for the relationship between socioeconomic status and body mass index

Maria Almudena Claassen; Olivier Klein; Boyka Bratanova; Nele Claes; Olivier Corneille

A negative association between socioeconomic status (SES) and levels of overweight/obesity is consistently found in high- and middle-income countries. Yet, there is little conclusive evidence about the mechanisms driving this association. In this systematic review, we discuss and compare the results of 22 studies that examine the role of psychosocial mediators in the association between SES and BMI in diverse population samples. These include factors related to resources and constraints in ones external neighborhood, social resources, and psychological factors such as stress. The findings support theoretical models indicating that SES is related to BMI partially through environmental and psychological factors. Importantly, SES often remains a significant predictor of weight status, indicating the importance of also addressing structural antecedents in order to improve health among lower SES populations. We thoroughly discuss the quality and limitations of current study designs and mediation testing and provide recommendations for future research.
