Addressing climate change with behavioral science: A global intervention tournament in 63 countries

Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interventions' effectiveness was small, largely limited to nonclimate skeptics, and differed across outcomes: Beliefs were strengthened mostly by decreasing psychological distance (by 2.3%), policy support by writing a letter to a future-generation member (2.6%), information sharing by negative emotion induction (12.1%), and no intervention increased the more effortful behavior-several interventions even reduced tree planting. Last, the effects of each intervention differed depending on people's initial climate beliefs. These findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.

Social and moral psychology of COVID-19 across 69 countries

The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public health behaviour, we present a dataset comprising of 51,404 individuals from 69 countries. This dataset was collected for the International Collaboration on Social & Moral Psychology of COVID-19 project (ICSMP COVID-19). This social science survey invited participants around the world to complete a series of moral and psychological measures and public health attitudes about COVID-19 during an early phase of the COVID-19 pandemic (between April and June 2020). The survey included seven broad categories of questions: COVID-19 beliefs and compliance behaviours; identity and social attitudes; ideology; health and well-being; moral beliefs and motivation; personality traits; and demographic variables. We report both raw and cleaned data, along with all survey materials, data visualisations, and psychometric evaluations of key variables.

Teaching open and reproducible scholarship: a critical review of the evidence base for current pedagogical methods and their outcomes

In recent years, the scientific community has called for improvements in the credibility, robustness and reproducibility of research, characterized by increased interest and promotion of open and transparent research practices. While progress has been positive, there is a lack of consideration about how this approach can be embedded into undergraduate and postgraduate research training. Specifically, a critical overview of the literature which investigates how integrating open and reproducible science may influence student outcomes is needed. In this paper, we provide the first critical review of literature surrounding the integration of open and reproducible scholarship into teaching and learning and its associated outcomes in students. Our review highlighted how embedding open and reproducible scholarship appears to be associated with (i) students' scientific literacies (i.e. students' understanding of open research, consumption of science and the development of transferable skills); (ii) student engagement (i.e. motivation and engagement with learning, collaboration and engagement in open research) and (iii) students' attitudes towards science (i.e. trust in science and confidence in research findings). However, our review also identified a need for more robust and rigorous methods within pedagogical research, including more interventional and experimental evaluations of teaching practice. We discuss implications for teaching and learning scholarship.

Victim-focused political apology predicts political support via perceived sincerity, trust and positive emotional climate: The case of the 2018 bushfire in Attica

Political leaders tend to apologize for wrongdoings. This study focuses on a disaster that occurred on July 2018 in east Attica, Greece, where wildfires destroyed houses and left dozens of people dead. Two pilot studies and one main study were conducted testing perceptions of apology as sincere, perceived trust, positive emotional climate and participants’ support towards the governmental policies. Participants (N = 180 for the two pilot studies, N = 222 for the main study) were recruited from the disaster zone of east Attica. The focus is on two key forms of political apology, a self or offender-focused apology and a self-other or victim-focused apology. Participants were randomly assigned to one of the conditions equivalent to each of the two forms of apology, that is either in a victim-focused apology condition or an offender-focused apology, or a control condition, where a neutral image was shown to participants. Results showed a positive association between victim-focused apology, compared to offender-focused apology, and political support towards the government via increased perceived sincerity, trust and positive emotional climate. Political and psychological implications related to different forms of public apologies are discussed.

Morality in the echo chamber: The relationship between belief in COVID-19 conspiracy theories and public health support and the mediating role of moral identity and morality-as-cooperation across 67 countries

Believing in conspiracy theories is a major problem, especially in the face of a pandemic, as these constitute a significant obstacle to public health policies, like the use of masks and vaccination. Indeed, during the COVID-19 pandemic, several ungrounded explanations regarding the origin of the virus or the effects of vaccinations have been rising, leading to vaccination hesitancy or refusal which poses as a threat to public health. Recent studies have shown that in the core of conspiracy theories lies a moral evaluation component; one that triggers a moral reasoning which reinforces the conspiracy itself. To gain a better understanding of how conspiracy beliefs about COVID-19 affect public health containment behaviors and policy support via morality-relevant variables, we analysed comprehensive data from the International Collaboration on the Social & Moral Psychology (ICSMP) of COVID-19, consisting of 49.965 participants across 67 countries. We particularly explored the mediating role of two levels of morality: individual and group-based morality. Results show that believing in conspiracy theories reduces adoption of containment health-related behaviors and policy support of public health measures, but moral identity and morality-as-cooperation significantly mediate this relationship. This means that beliefs in conspiracy theories do not simply constitute antecedents of cognitive biases or failures, nor maladaptive behaviors based on personality traits, but are morally infused and should be dealt as such. Based on our findings, we further discuss the psychological, moral, and political implications of endorsement of conspiracy theories in the era of the pandemic.

Predicting attitudinal and behavioral responses to COVID-19 pandemic using machine learning

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multinational data collected by the International Collaboration on the Social and Moral Psychology of COVID-19 (N = 51,404) to test the predictive efficacy of constructs from social, moral, cognitive, and personality psychology, as well as socio-demographic factors, in the attitudinal and behavioral responses to the pandemic. The results point to several valuable insights. Internalized moral identity provided the most consistent predictive contribution-individuals perceiving moral traits as central to their self-concept reported higher adherence to preventive measures. Similar results were found for morality as cooperation, symbolized moral identity, self-control, open-mindedness, and collective narcissism, while the inverse relationship was evident for the endorsement of conspiracy theories. However, we also found a non-neglible variability in the explained variance and predictive contributions with respect to macro-level factors such as the pandemic stage or cultural region. Overall, the results underscore the importance of morality-related and contextual factors in understanding adherence to public health recommendations during the pandemic.

National identity predicts public health support during a global pandemic

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g., spatial distancing and stricter hygiene) and endorsed public policy interventions (e.g., closing bars and restaurants) during the early stage of the COVID-19 pandemic (April-May 2020). Respondents who reported identifying more strongly with their nation consistently reported greater engagement in public health behaviours and support for public health policies. Results were similar for representative and non-representative national samples. Study 2 (N = 42 countries) conceptually replicated the central finding using aggregate indices of national identity (obtained using the World Values Survey) and a measure of actual behaviour change during the pandemic (obtained from Google mobility reports). Higher levels of national identification prior to the pandemic predicted lower mobility during the early stage of the pandemic (r = -0.40). We discuss the potential implications of links between national identity, leadership, and public health for managing COVID-19 and future pandemics.

Trust predicts COVID-19 prescribed and discretionary behavioral intentions in 23 countries

The worldwide spread of a new coronavirus (SARS-CoV-2) since December 2019 has posed a severe threat to individuals' well-being. While the world at large is waiting that the released vaccines immunize most citizens, public health experts suggest that, in the meantime, it is only through behavior change that the spread of COVID-19 can be controlled. Importantly, the required behaviors are aimed not only at safeguarding one's own health. Instead, individuals are asked to adapt their behaviors to protect the community at large. This raises the question of which social concerns and moral principles make people willing to do so. We considered in 23 countries (N = 6948) individuals' willingness to engage in prescribed and discretionary behaviors, as well as country-level and individual-level factors that might drive such behavioral intentions. Results from multilevel multiple regressions, with country as the nesting variable, showed that publicized number of infections were not significantly related to individual intentions to comply with the prescribed measures and intentions to engage in discretionary prosocial behaviors. Instead, psychological differences in terms of trust in government, citizens, and in particular toward science predicted individuals' behavioral intentions across countries. The more people endorsed moral principles of fairness and care (vs. loyalty and authority), the more they were inclined to report trust in science, which, in turn, statistically predicted prescribed and discretionary behavioral intentions. Results have implications for the type of intervention and public communication strategies that should be most effective to induce the behavioral changes that are needed to control the COVID-19 outbreak.

“Historia est magistra vitae”? The impact of historical victimhood on current conspiracy beliefs

Conspiracy beliefs constitute a propensity to attribute major events to powerful agents acting against less powerful “victims”. In this article we test whether collective victimhood facilitates conspiracy thinking. Study 1 showed that perceived group victimhood is associated with generic and group-specific conspiracy beliefs, but only for individuals who identify highly with their ingroup. Study 2 employed an experimental design to show that experimentally increased group victimhood leads to increased endorsement of conspiracy beliefs among high ingroup identifiers, but decreases endorsement of conspiracy beliefs among low identifiers. This effect was mediated by lack of trust towards outgroup members. Study 3 sought to replicate Study 2 in a different socio-political context. While Study 3 did not directly support the relationship between victimhood, group identification and conspiracy beliefs, an integrated meta-analysis of all three studies provides evidence for a significant interaction of victimhood and group identification in predicting conspiracy beliefs.

Identity entrepreneurship in political commemorations: A longitudinal quantitative content analysis of commemorative speeches by leaders of parties in power and opposition before and during the Greek economic crisis

This study analyses quantitatively the content of thirty-nine political speeches made by political leaders of three political parties – New Democracy, Panhellenic Socialist Movement (PASOK) and Coalition of the Radical Left (SYRIZA) – of different status represented in the Greek parliament. The leaders of these parties release annual commemorative speeches of the restoration of Greek democracy on 24th July 1974. The focus of this study is on longitudinally analysing the content of commemorative speeches, looking at how political leaders communicate the historical event, by quantifying through a content analysis various forms of ingroups and outgroups in their annual commemorations. Such constructions were ventured during a period of 13 years, from 2004 to 2016, before and during the break out of financial crisis in 2010. Longitudinal quantitative content analysis identified differences in the use of we-referencing and they-referencing language, varying per status of parties and context of release of commemorative speeches. I view commemorative speeches as a non-neutral history-related business that requires mobilisation of audiences in different ways and different contexts. Implications of commemorating the historical past across time as institutional identity practice are discussed.

Nostalgic memories and human rights: Integrating subjective experiences with universal needs

In this comment, I focus on the integration of memories and human rights. The claim for the “self-evident” declares the claim for human rights not only of minorities, or oppressed and forgotten groups but, more broadly, of the self and different others. I consider human rights as they emerge from the content of intergenerational nostalgic memories and are reflected on the right to remember, the right to forget, the right to long for the past, and the right to life. I give a brief account of studies on intergenerational nostalgic memories and I argue for remembering processes as a fundamental human right. Finally, I discuss theoretical implications of integrating memory studies and human rights debates.

Traumatic Rift: How Conspiracy Beliefs Undermine Cohesion After Societal Trauma?

Collective traumas may often lead to deep societal divides and internal conflicts. In this article, we propose that conspiracy theories emerging in response to victimizing events may play a key role in the breakdown of social cohesion. We performed a nationally representative survey in Poland (N = 965) two years after the Smoleńsk airplane crash in which the Polish president was killed, together with 95 political officials and high-ranking military officers. The survey found that people endorsing conspiratorial accounts of the Smoleńsk catastrophe preferred to distance themselves from conspiracy non-believers, while skeptics preferred greater distance to conspiracy believers. We also examined the role of people’s belief in the uniqueness of in-group historical suffering as an important antecedent of both conspiracy thinking and hostility towards outgroups (conspiracy believers and non-believers).

Commemoration in crisis: A discursive analysis of who 'we' and 'they' have been or become in ceremonial political speeches before and during the Greek financial downturn

This study analyses the discourse of statements of the leaders of two Greek political parties commemorating the restoration of Greek democracy on 24 July 1974; the ruling party New Democracy and the opposition, Coalition of the Radical Left. We focus on how these leaders act as entrepreneurs of their identities by constructing their ingroups in broad or narrow terms and their outgroups in vague or specific terms. These constructions were ventured during a period of relative political stability (2008) and instability (2012), and we focus on how ingroup prototypes and group boundaries are narrated across Greece's past, present and future in ambiguous or concrete terms. The study aligns the social identity approach to political leadership with studies on political discourse and 'the rhetoric of we'. We view commemorative statements as historical charters and respond to calls for discourse analysis to take greater account of historical context. The findings suggest concrete hypotheses about how leaders with different amounts of political support might define, as identity entrepreneurs, who 'we' are, and who 'we' are not in democratic contexts marked by stability or crisis.

Older adults' decoding of emotions: age-related differences in interpreting dynamic emotional displays and the well-preserved ability to recognize happiness

AIM

Although the ability to recognize emotions through bodily and facial muscular movements is vital to everyday life, numerous studies have found that older adults are less adept at identifying emotions than younger adults. The message gleaned from research has been one of greater decline in abilities to recognize specific negative emotions than positive ones. At the same time, these results raise methodological issues with regard to different modalities in which emotion decoding is measured. The main aim of the present study is to identify the pattern of age differences in the ability to decode basic emotions from naturalistic visual emotional displays.

METHOD

The sample comprised a total of 208 adults from Greece, aged from 18 to 86 years. Participants were examined using the Emotion Evaluation Test, which is the first part of a broader audiovisual tool, The Awareness of Social Inference Test. The Emotion Evaluation Test was designed to examine a person's ability to identify six emotions and discriminate these from neutral expressions, as portrayed dynamically by professional actors.

RESULTS

The findings indicate that decoding of basic emotions occurs along the broad affective dimension of uncertainty, and a basic step in emotion decoding involves recognizing whether information presented is emotional or not. Age was found to negatively affect the ability to decode basic negatively valenced emotions as well as pleasant surprise. Happiness decoding is the only ability that was found well-preserved with advancing age.

CONCLUSION

The main conclusion drawn from the study is that the pattern in which emotion decoding from visual cues is affected by normal ageing depends on the rate of uncertainty, which either is related to decoding difficulties or is inherent to a specific emotion.
