RESUMO

OBJECTIVE: To explore the differences in social norms around parents' food provision in different provision contexts and by demographics. DESIGN: Qualitative study using story completion methodology via an online survey in September 2021. Adults 18+ with or without children were randomised to one of three story stems focusing on food provision in different contexts; food provision at home (non-visitor), with visitors present and with the involvement of sport. Stories were coded and themed using thematic analysis. A content analysis was performed to determine count and frequency of codes in stories by participant demographics and story assumptions. SETTING: Australia. PARTICIPANTS: Adults (n 196). RESULTS: Nine themes were identified from the data resulting in four social norms around providing healthy foods and justifying non-adherence to healthy eating guidelines, evolution of family life and mealtime values, the presence of others influencing how we engage with food provision and unhealthy foods used as incentives/rewards in sport. Following content analysis, no differences of themes or norms by participant demographics or story assumptions were found. CONCLUSIONS: We identified pervasive social norms around family food provision and further identified how contextual factors resulted in variations or distinct norms. This highlights the impact context may have on the social norms parents face when providing food to their children and the opportunities and risks of leveraging these social norms to influence food choice in these contexts. Public health interventions and practitioners should understand the influence of context and social environments when promoting behaviour change and providing individualised advice. Future research could explore parents' experiences of these norms and to what extent they impact food choice.

RESUMO

Misinformation on social media is a pervasive challenge. In this study (N = 415) a social-media simulation was used to test two potential interventions for countering misinformation: a credibility badge and a social norm. The credibility badge was implemented by associating accounts, including participants', with a credibility score. Participants' credibility score was dynamically updated depending on their engagement with true and false posts. To implement the social-norm intervention, participants were provided with both a descriptive norm (i.e., most people do not share misinformation) and an injunctive norm (i.e., sharing misinformation is the wrong thing to do). Both interventions were effective. The social-norm intervention led to reduced belief in false claims and improved discrimination between true and false claims. It also had some positive impact on social-media engagement, although some effects were not robust to alternative analysis specifications. The presence of credibility badges led to greater belief in true claims, lower belief in false claims, and improved discrimination. The credibility-badge intervention also had robust positive impacts on social-media engagement, leading to increased flagging and decreased liking and sharing of false posts. Cumulatively, the results suggest that both interventions have potential to combat misinformation and improve the social-media information landscape.

RESUMO

The use of electronic cigarettes (e-cigarettes) is common and increasing, especially among youth. In 2022/2023, 30% of 12- to 17-year-olds reported ever using e-cigarettes in Australia-a >50% increase from 2017 (14%). Several adverse e-cigarette health effects have been identified and most effects remain unknown. Social norms, rules that govern social behaviours, are associated with current and future adolescent e-cigarette use. Understanding social norms in Australian adolescents is critical to the development of targeted and effective e-cigarette prevention activities. This study aims to explore e-cigarette social norms among adolescents living in New South Wales, Australia. A total of 32 online single or paired semi-structured qualitative interviews were conducted involving 46 participants aged 14-17 years, as part of the Generation Vape project. Reflexive thematic analysis was applied within a constructivist perceptive. Adolescents perceived e-cigarettes use as prolific among their peers, with use considered common, acceptable and normal. Fuelled by social exposure to e-cigarettes, 'everyone' was generally thought to be using them (descriptive norms). E-cigarette use was considered so entrenched that it was part of adolescent identity, with abstinence regarded as atypical. Use was driven by an internalised desire to fit it (injunctive norm), rather than being attributed to overt/external 'peer-pressure'. Positive e-cigarette norms exist among Australian adolescents with norm formation strongly influenced by social exposure, including e-cigarette promotion. Prevention efforts should include limiting adolescent exposure to e-cigarette marketing to help redefine existing pro-e-cigarette social norms and protect health.

RESUMO

How does threat from disease shape our cooperative actions and the social norms that guide such behaviour? To study these questions, we draw on a collective-risk social dilemma experiment that we ran before the emergence of the Covid-19 pandemic (Wave 1, 2018) and compare this to its exact replication, sampling from the same population, that we conducted during the first wave of the pandemic (Wave 2, 2020). Tightness-looseness theory predicts and evidence generally supports that both cooperation and accompanying social norms should increase, yet, we mostly did not find this. Contributions, the probability of reaching the threshold (cooperation), and the contents of the social norm (how much people should contribute) remained similar across the waves, although the strength of these social norms were slightly greater in Wave 2. We also study whether the results from Wave 1 that should not be affected by the pandemic-the relationship between social norms and cooperation and specific behavioural types-replicate in Wave 2 and find that these results generally hold. Overall, our work demonstrates that social norms are important drivers of cooperation, yet, communicable diseases, at least in the short term, have little or no effects on either.

RESUMO

Over the past decade there has been a burgeoning literature on social norms and the need to understand their context-specific patterning and trends to promote change, including to address the harmful practice of female genital mutilation (FGM), which affects around 200 million girls and women globally. This article draws on mixed-methods data collected in 2022 and 2023 with 1,020 adolescents and their caregivers, as well as key informants, from Ethiopia's Somali region to explore the patterning, drivers, and decision-making around FGM. Findings indicate that almost all Somali girls can expect to undergo FGM before age 15, and that infibulation is near universal. Critically, however, we find that respondents' understanding of infibulation is rooted in traditional practice, and many girls are now "partially" infibulated-an invasive procedure that girls nonetheless see as an improvement over the past. These shifts reflect religious leaders' efforts to eliminate traditional infibulation--and the health risks it entails--by promoting "less invasive" types of FGM as a requirement of Islam. We also find evidence of emergent medicalization of the practice, as mothers-who are the primary decision-makers-seek to further reduce risks. Adult and adolescent respondents agree that FGM is a deeply embedded social norm, but distinguish between FGM as a perceived religious requirement, and infibulation as a cultural requirement. For girls and women, the importance of FGM is framed around social acceptance, whereas boys and men focus on FGM as a requirement for marriage as it allows families to control girls' sexuality. The article concludes by reflecting on the implications of our findings for programming in high-prevalence contexts. Key conclusions include that FGM interventions should not rely on empowering individuals as "champions of change" but rather prioritize engagement with whole communities, and should be open in the short term to incremental harm-reduction approaches.

RESUMO

Background: Elimination of girl child marriage (CM) globally at the current pace is projected to take about 300 years. Thus, innovative and effective solutions are urgently warranted. Bangladesh reports one of the highest rates of CM in the world. We present the impact of Tipping Point Initiative (TPI), a combined intervention to empower girls and to address social norms on CM in Bangladesh. Methods: A three-arm non-blinded Cluster Randomised Controlled Trial was conducted in 51 villages/clusters in a sub-district of Bangladesh. Clusters were randomly assigned to the arms: Tipping Point Program (TPP), Tipping Point Program Plus (TPP+), and Pure Control. TPP conducted 40 weekly single-gender group sessions with never-married adolescent girls and boys recruited at 12 -<16 years; and 18-monthly gender-segregated group sessions with the parents. On top of TPP, TPP+ included cross-gender and -generation dialogues, girls' movement building and girl-led community sensitisation. Intention-to-treat analysis was performed to assess the impact of TPI on the hazard of CM, the primary outcome. The impact of girls' session attendance on CM was also assessed. At baseline 1275 girls (TPP = 412; TPP+ = 420; Control = 443) were interviewed between February-April 2019. At endline 1123 girls (TPP = 363; TPP + = 366; Control = 394) were interviewed and included in the analyses. Results: No intervention impact was detected on the full sample (TPP vs. Control: adjusted hazard ratio (aHR) = 1.14; 95% CI = 0.79-1.63, P = 0.47), (TPP + vs. Control: aHR = 1.24; 95% CI = 0.89-1.71, P = 0.19, (TPP vs. TPP+: aHR = 1.03; 95% CI = 0.72-1.47, P = 0.87). However, in the TPP arm, the hazard of CM was reduced by 54% (aHR = 0.46; 95% CI = 0.23-0.92, P = 0.03) among the girls in the highest tertile of session attendance, compared to the lowest. In the TPP+ arm, this hazard was reduced by 49% (aHR = 0.51; 95% CI = 0.23-0.92, P = 0.03) among girls in the highest tertile, compared to the lowest tertile. Conclusions: Although TPI did not show an effect on CM in any of the intervention arms, within each intervention arm, a positive effect was detected in reducing CM among girls in the highest tertile of session attendance despite implementation challenges due to COVID-19. Registration: Clinicaltrials.gov: NCT03965273; Date: 29 May 2019.

RESUMO

The emergence of COVID-19 dramatically changed social behavior across societies and contexts. Here we study whether social norms also changed. Specifically, we study this question for cultural tightness (the degree to which societies generally have strong norms), specific social norms (e.g. stealing, hand washing), and norms about enforcement, using survey data from 30,431 respondents in 43 countries recorded before and in the early stages following the emergence of COVID-19. Using variation in disease intensity, we shed light on the mechanisms predicting changes in social norm measures. We find evidence that, after the emergence of the COVID-19 pandemic, hand washing norms increased while tightness and punishing frequency slightly decreased but observe no evidence for a robust change in most other norms. Thus, at least in the short term, our findings suggest that cultures are largely stable to pandemic threats except in those norms, hand washing in this case, that are perceived to be directly relevant to dealing with the collective threat.

RESUMO

Social norms are foundational to human cooperation and co-existence in social groups. A crucial marker of social norms is that a behavior is not only shared, but that the conformity to the behavior of others is a basis for social evaluation (i.e., reinforcement and sanctioning), taking the is, how individuals usually behave, to an ought, how individuals should behave to be socially approved by others. In this preregistered study, we show that 11-month-old infants grasp this fundamental aspect about social norms already in their first year. They showed a pupillary surprise response for unexpected social responses, namely the disapproval and exclusion of an individual who showed the same behavior like others or the approval and inclusion of an individual who behaved differently. That preverbal infants link the conformity with others' behavior to social evaluations, before they respond to norm violations themselves, indicates that the foundations of social norm understanding lie in early infancy.

RESUMO

OBJECTIVES: Harmful gender and social norms prescribe divergent opportunities for girls and boys and drive child marriage. This systematic review examines the scope, range and effectiveness of interventions to change social norms and delay child marriage. DESIGN: We systematically assess the contributions made by interventions that work to shift norms to prevent child marriage or to limit its harmful consequences. Our analysis classifies each study's quality in evaluation and implementation design regarding shifting norms. DATA SOURCES: We conducted a search of electronic databases (PubMed, PsycINFO, Embase, CINAHL Plus, Popline, Web of Science and Cochrane Library) and grey literature (targeted hand-searches of 15 key organisations and Google Scholar). ELIGIBILITY CRITERIA: Included interventions sought to change norms related to child marriage, were evaluated in experimental or quasi-experimental evaluations, collected data on age at marriage and norms/attitudes, and were published in English from January 2000 to September 2021. DATA EXTRACTION AND SYNTHESIS: We used a standardised form to extract data from all eligible studies, and double-screened to validate coding and reporting. We classified the studies by low, medium and high quality for evaluation and risk of bias, and separately by the extent to which they addressed social norms. RESULTS: Our assessment of the 12 eligible studies identified revealed little evidence of a systematic relationship between social norms related to marriage and changes in child marriage behaviours. We found stronger evidence of programme effect on child marriage outcomes than on social norms, though only a minority of studies found an effect for either. Studies that appeared effective in changing child marriage norms varied greatly in scale and extent of programming, and few attempted to identify the appropriate reference groups for measuring social norms. CONCLUSION: The studies evaluated by our review provide only weak evidence on the impact of interventions on norms, and on the link between shifts in norms and marriage behaviour.

RESUMO

Digital technologies are pervasive in every aspect of our daily lives. The proliferation of such technologies has also influenced the conduct of biomedical, behavioral, and social research. The articles in this special issue provide illustrative examples of the range of applications of digital technologies in psychological science research across a variety of populations. They highlight ethical, legal, and social issues that emerge when digital technologies are employed in psychological science research in the current era of rapid technological change, increasing prevalence of interdisciplinary team science, evolving understandings of ethical precepts and social norms, and promoting open science. This introduction to the special issue provides an overview of challenges to the Belmont principles of respect for persons, beneficence, and justice revealed in the 10 articles. The conclusions reached are that these ethical principles do not always adapt well to the digital environment and that practices cannot always be uniquely classified under one of these three headings. We recommend that conceptual work and practical guidance be undertaken to expand the interpretation of these principles in the light of evolving societal norms and emerging ethical issues.

RESUMO

Mechanisms of social control reinforce norms that appear harmful or wasteful, such as mutilation practises or extensive body tattoos. We suggest such norms arise to serve as signals that distinguish between ingroup 'friends' and outgroup 'foes', facilitating parochial cooperation. Combining insights from research on signalling and parochial cooperation, we incorporate a trust game with signalling in an agent-based model to study the dynamics of signalling norm emergence in groups with conflicting interests. Our results show that costly signalling norms emerge from random acts of signalling in minority groups that benefit most from parochial cooperation. Majority groups are less likely to develop costly signalling norms. Yet, norms that prescribe sending costless group identity signals can easily emerge in groups of all sizes-albeit, at times, at the expense of minority group members. Further, the dynamics of signalling norm emergence differ across signal costs, relative group sizes, and levels of ingroup assortment. Our findings provide theoretical insights into norm evolution in contexts where groups develop identity markers in response to environmental challenges that put their interests at odds with the interests of other groups. Such contexts arise in zones of ethnic conflict or during contestations of existing power relations. This article is part of the theme issue 'Social norm change: drivers and consequences'.

RESUMO

Previous studies have used various normative expressions such as 'should', 'appropriate' and 'approved' interchangeably to communicate injunctions and social norms. However, little is known about whether people's interpretations of normative language differ and whether behavioural responses might vary across them. In two studies (total n = 2903), we find that compliance is sensitive to the types of normative expressions and how they are used. Specifically, people are more likely to comply when the message is framed as an injunction rather than as what most people consider good behaviour (social norm framing). Behaviour is influenced by the type of normative expression when the norm is weak (donation to charities), not so when the norm is strong (reciprocity). Content analysis of free responses reveals individual differences in the interpretation of social norm messages, and heterogeneous motives for compliance. Messages in the social norm framing condition are perceived to be vague and uninformative, undermining their effectiveness. These results suggest that careful choice of normative expressions is in order when using messages to elicit compliance, especially when the underlying norms are weak. This article is part of the theme issue 'Social norm change: drivers and consequences'.

RESUMO

Interventions to counter misinformation are often less effective for polarizing content on social media platforms. We sought to overcome this limitation by testing an identity-based intervention, which aims to promote accuracy by incorporating normative cues directly into the social media user interface. Across three pre-registered experiments in the US (N = 1709) and UK (N = 804), we found that crowdsourcing accuracy judgements by adding a Misleading count (next to the Like count) reduced participants' reported likelihood to share inaccurate information about partisan issues by 25% (compared with a control condition). The Misleading count was also more effective when it reflected in-group norms (from fellow Democrats/Republicans) compared with the norms of general users, though this effect was absent in a less politically polarized context (UK). Moreover, the normative intervention was roughly five times as effective as another popular misinformation intervention (i.e. the accuracy nudge reduced sharing misinformation by 5%). Extreme partisanship did not undermine the effectiveness of the intervention. Our results suggest that identity-based interventions based on the science of social norms can be more effective than identity-neutral alternatives to counter partisan misinformation in politically polarized contexts (e.g. the US).

RESUMO

Human communities teem with a variety of social norms. In order to change unjust and harmful social norms, it is crucial to identify the psychological processes that give rise to them. Most researchers take it for granted that social norms are uniquely human. By contrast, we approach this matter from a comparative perspective, leveraging recent research on animal social behaviour. While there is currently only suggestive evidence for norms in nonhuman communities, we argue that human social norms are likely produced by a wide range of mechanisms, many of which we share with nonhuman animals. Approaching this variability from a comparative perspective can help norm researchers expand and reframe the range of hypotheses they test when attempting to understand the causes of socially normative behaviours in humans. First, we diagnose some of the theoretical obstacles to developing a comparative science of social norms, and offer a few basic constructs and distinctions to help norm researchers overcome these obstacles. Then we develop a six-dimensional model of the psychological and social factors that contribute to variability in both human and potential nonhuman norms. This article is part of the theme issue 'Social norm change: drivers and consequences'.

RESUMO

Across human societies, people are sometimes willing to punish norm violators. Such punishment can take the form of revenge from victims, seemingly altruistic intervention from third parties, or legitimized sanctioning from institutional representatives. Although prior work has documented cross-cultural regularities in norm enforcement, substantial variation exists in the prevalence and forms of punishment across societies. Such cross-societal variation may arise from universal psychological mechanisms responding to different socio-ecological conditions, or from cultural evolutionary processes, resulting in different norm enforcement systems. To date, empirical evidence from comparative studies across diverse societies has remained disconnected, owing to a lack of interdisciplinary integration and a prevalent tendency of empirical studies to focus on different underpinnings of variation in norm enforcement. To provide a more complete view of the shared and unique aspects of punishment across societies, we review prior research in anthropology, economics and psychology, and take a first step towards integrating the plethora of socio-ecological and cultural factors proposed to explain cross-societal variation in norm enforcement. We conclude by discussing how future cross-societal research can use diverse methodologies to illuminate key questions on the domain-specificity of punishment, the diversity of tactics supporting social norms, and their role in processes of norm change. This article is part of the theme issue 'Social norm change: drivers and consequences'.

RESUMO

Global challenges like the climate crisis and pandemic outbreaks require collective responses where people quickly adapt to changing circumstances. Social norms are potential solutions, but only if they themselves are flexible enough. The COVID-19 pandemic provided a unique opportunity to study norm formation and decay in real-world contexts. We tracked empirical and normative expectations about social distancing and empirical and normative expectations of sanctioning from June 2021 to February 2022 to explore how norms and meta norms evolved as COVID-19 risk decreased and increased. We found that norms and meta norms partially coevolve with risk dynamics, although they recover with some delay. This implies that norms should be enforced as soon as risk increases. We therefore tested how sanctioning intentions vary for different hypothetical norms and find them to increase with a clear meta norm of sanctioning, yet decrease with a clear social norm of distance. In conclusion, social norms evolve spontaneously with changing risk, but might not be adaptive enough when the lack of meta norms of sanctioning introduce tolerance for norm violations. Moreover, norm nudges can potentially have negative externalities if strengthening the social norm increases tolerance for norm violations. These results put some limits to social norms as solutions to guide behaviour under risk. This article is part of the theme issue 'Social norm change: drivers and consequences'.

RESUMO

We review theoretical approaches for modelling the origin, persistence and change of social norms. The most comprehensive models describe the coevolution of behaviours, personal, descriptive and injunctive norms while considering influences of various authorities and accounting for cognitive processes and between-individual differences. Models show that social norms can improve individual and group well-being. Under some conditions though, deleterious norms can persist in the population through conformity, preference falsification and pluralistic ignorance. Polarization in behaviour and beliefs can be maintained, even when societal advantages of particular behaviours or belief systems over alternatives are clear. Attempts to change social norms can backfire through cognitive processes including cognitive dissonance and psychological reactance. Under some conditions social norms can change rapidly via tipping point dynamics. Norms can be highly susceptible to manipulation, and network structure influences their propagation. Future models should incorporate network structure more thoroughly, explicitly study online norms, consider cultural variations and be applied to real-world processes. This article is part of the theme issue 'Social norm change: drivers and consequences'.

RESUMO

Applied cultural evolution includes any effort to mobilize social learning and cultural evolution to promote behaviour change. Social tipping is one version of this idea based on conformity and coordination. Conformity and coordination can reinforce a harmful social norm, but they can also accelerate change from a harmful norm to a beneficial alternative. Perhaps unfortunately, the link between the size of an intervention and social tipping is complex in heterogeneous populations. A small intervention targeted at one segment of society can induce tipping better than a large intervention targeted at a different segment. We develop and examine two models showing that the link between social tipping and social welfare is also complex in heterogeneous populations. An intervention strategy that creates persistent miscoordination, exactly the opposite of tipping, can lead to higher social welfare than another strategy that leads to tipping. We show that the potential benefits of miscoordination often hinge specifically on the preferences of people most resistant to behaviour change. Altogether, ordinary forms of heterogeneity complicate applied cultural evolution considerably. Heterogeneity weakens both the link between the size of a social planner's intervention and behaviour change and the link between behaviour change and the well-being of society.

RESUMO

This study reports on an experimental test of the effects of descriptive and injunctive norm appeals on intentions to prevent food waste in China and the United States (N = 1449), testing the role of cultural context and group orientation in this process. Results showed that the main effects of descriptive and injunctive norm messages on behavioural intentions were mediated by normative perceptions, and cultural context moderated both paths of this mediation. Specifically, with the same message exposure, Chinese participants perceived food waste prevention as more prevalent and socially approved compared to US participants. Normative perceptions interacted with cultural context to influence behavioural intentions, such that both descriptive and injunctive norm perceptions predicted stronger intentions to prevent food waste among Chinese participants compared to Americans. Group orientation yielded a main effect on behavioural intentions, instead of the moderation effects as expected. Findings suggest the need for culturally grounded and contextualized approaches to communication of social norms, as well as building cultural concepts into theories of social norms.
