The effects of communicating uncertainty on public trust in facts and numbers.

Uncertainty is inherent to our knowledge about the state of the world yet often not communicated alongside scientific facts and numbers. In the "posttruth" era where facts are increasingly contested, a common assumption is that communicating uncertainty will reduce public trust. However, a lack of systematic research makes it difficult to evaluate such claims. We conducted five experiments-including one preregistered replication with a national sample and one field experiment on the BBC News website (total n = 5,780)-to examine whether communicating epistemic uncertainty about facts across different topics (e.g., global warming, immigration), formats (verbal vs. numeric), and magnitudes (high vs. low) influences public trust. Results show that whereas people do perceive greater uncertainty when it is communicated, we observed only a small decrease in trust in numbers and trustworthiness of the source, and mostly for verbal uncertainty communication. These results could help reassure all communicators of facts and science that they can be more open and transparent about the limits of human knowledge.

Beliefs about the nature of knowledge shape responses to the pandemic: Epistemic beliefs, the Dark Factor of Personality, and COVID-19-related conspiracy ideation and behavior.

OBJECTIVE: Global challenges such as climate change or the COVID-19 pandemic have drawn public attention to conspiracy theories and citizens' non-compliance to science-based behavioral guidelines. We focus on individuals' worldviews about how one can and should construct reality (epistemic beliefs) to explain the endorsement of conspiracy theories and behavior during the COVID-19 pandemic and propose the Dark Factor of Personality (D) as an antecedent of post-truth epistemic beliefs. METHOD AND RESULTS: This model is tested in four pre-registered studies. In Study 1 (N = 321), we found first evidence for a positive association between D and post-truth epistemic beliefs (Faith in Intuition for Facts, Need for Evidence, Truth is Political). In Study 2 (N = 453), we tested the model proper by further showing that post-truth epistemic beliefs predict the endorsement of COVID-19 conspiracies and disregarding COVID-19 behavioral guidelines. Study 3 (N = 923) largely replicated these results at a later stage of the pandemic. Finally, in Study 4 (N = 513), we replicated the results in a German sample, corroborating their cross-cultural validity. Interactions with political orientation were observed. CONCLUSION: Our research highlights that epistemic beliefs need to be taken into account when addressing major challenges to humankind.

Changes in society and young people's mental health1.

It is well recognized that many psychiatric disorders are strongly influenced by cultural and social factors. Foucault's account of the modern development links together 'madness', psychiatry and the asylum. We pick up the story at the point Foucault left it, the mid-twentieth century, to examine cultural and social processes that are reshaping concepts, discourse and practices - the 'social imaginary' - around mental health, with particular reference to the apparent rise in mental health problems among the young. We conclude that this apparent rise may reflect cultural and social changes in representations of mental health. In addition, over recent decades there have been increasingly evident fractures in social solidarity, interacting with and exacerbating specific socio-political-economic-environmental stressors on younger generations, including increasing intergenerational wealth inequalities and accelerating environmental concerns.

The vaccination debate in the "post-truth" era: social media as sites of multi-layered reflexivity.

This paper analyses the contemporary public debate about vaccination, and medical knowledge more broadly, in the context of social media. The study is focused on the massive online debate prompted by the Facebook status of the digital celebrity Mark Zuckerberg, who posted a picture of his two-month-old daughter, accompanied by a comment: 'Doctor's visit - time for vaccines!' Carrying out a qualitative analysis on a sample of 650 comments and replies, selected through systematic random sampling from an initial pool of over 10,000 user contributions, and utilising open and axial coding, we empirically inform the theoretical discussion around the concept of the reflexive patient and introduce the notion of multi-layered reflexivity. We argue that the reflexive debate surrounding this primarily medical problem is influenced by both biomedical and social scientific knowledge. Lay actors therefore discuss not only vaccination, but also its political and economic aspects as well as the post-truth information context of the debate. We stress that the reflexivity of social actors related to the post-truth era re-enters and influences the debate more than ever. Furthermore, we suggest that the interconnection of different layers of reflexivity can either reinforce certainty or deepen the ambiguity and uncertainty of reflexive agents.

Why public dismissal of nutrition science makes sense: Post-truth, public accountability and dietary credibility.

PURPOSE: The purpose of this paper is to critically engage with societal origins of public (dis)trust and public credibility of nutrition science and offer suggestions for addressing its public dismissal. DESIGN/METHODOLOGY/APPROACH: This viewpoint presents a conceptual analysis of public dismissal of nutrition science, drawing together perspectives on the relationships between science and society from the history, sociology and philosophy of science. FINDINGS: The origin of trust amongst scientists relies is actively tied to their social and moral status and science as a cultural activity is inextricably linked to institutions of power. Accordingly, trust in science relies heavily on public perceptions of those institutions, the ways in which citizens feel represented by them, and to what extent citizens consider these institutions to be held accountable. Ignoring this origin leads to expectations of science and scientists they cannot live up to and inevitable disappointment in those holding such expectations. SOCIAL IMPLICATIONS: Managing responsible expectations asks that we first dismiss dominant portrayals of science as pure, neutral, value-free and fuelled by curiosity. Second, we should pursue a reorganisation of science, favouring social inclusiveness over scientific exceptionalism. ORIGINALITY/VALUE: Post-truth dynamics are a source of concern in the dissemination of nutrition science. Rather than dismissing it as a consequence of public ignorance, a comprehensive engagement with post-truth arguments allows a constructive repositioning of nutrition science organisation and communication. It asks that we design research programmes and studies differently, incorporate different voices. Above all else, it asks humility of researchers and tolerant approaches to other perspectives.

No funeral bells: Public reason in a 'post-truth' age.

The label 'post-truth' signals for many a troubling turn away from principles of enlightened government. The word 'post', moreover, implies a past when things were radically different and whose loss should be universally mourned. In this paper, we argue that this framing of 'post-truth' is flawed because it is ahistorical and ignores the co-production of knowledge and norms in political contexts. Debates about public facts are necessarily debates about social meanings, rooted in realities that are subjectively experienced as all-encompassing and complete, even when they are partial and contingent. Facts used in policy are normative in four ways: They are embedded in prior choices of which experiential realities matter, produced through processes that reflect institutionalized public values, arbiters of which issues are open to democratic contestation and deliberation, and vehicles through which polities imagine their collective futures. To restore truth to its rightful place in democracy, governments should be held accountable for explaining who generated public facts, in response to which sets of concerns, and with what opportunities for deliberation and closure.

STS as science or politics?

In a recent editorial for this journal, Sergio Sismondo makes two claims. First, he states that STS bears no responsibility for the emergence of post-truth politics. Second, he claims that debates about the nature of expertise that take place within STS are irrelevant in this context. In contrast, we argue that, whether or not STS had a causal influence on the emergence of post-truth politics, there is a clear resonance between the two positions and that the current political climate makes the empirically informed and scientific analysis of expertise and the form of life of science more important than ever. We argue that treating the contribution of STS to these matters as essentially political rather than scientific surrenders any special role we have as experts on the organization and values of science and leaves STS as just one political actor among others.

STS, symmetry and post-truth.

This essay takes up a series of questions about the connection between 'symmetry' in Science and Technology Studies (STS) and 'post-truth' in contemporary politics. A recent editorial in this journal by Sergio Sismondo argues that current discussions of 'post-truth' have little to do with conceptions of 'symmetry' or with concerns about 'epistemic democracy' in STS, while others, such as Steve Fuller and Harry Collins, insist that there are such connections. The present essay discusses a series of questions about the meaning of 'post-truth' and 'symmetry', and the connections of those concepts to each other and to 'epistemic democracy'. The essay ends with a series of other questions about STS and contemporary politics, and an invitation to further discussions.

Values and vendettas: Populist science governance in Mexico.

This article aims to diversify STS perspectives on populism by addressing a sequence of episodes of Mexican science policy in terms of clashes between populism and scientific communities. The article describes a reorientation of Mexican science policy that has destabilized the academic system during the present administration. Specifically, it looks at the legislative project initiated by Mexico's National Science and Technology Council (Conacyt) to overhaul the national regulatory framework on science, technology and innovation, and controversial political actions taken by Conacyt against the scientific community. Contextualizing these grievances, the article concludes that at stake is a form of 'trickle-down populism' that, through systematic authoritarianism, seeks to impose on the academic community a model of 'populist science governance'.

Factors influencing the update of beliefs regarding controversial political issues.

Selectively integrating new information contributes to belief polarization and compromises public discourse. To better understand factors that underlie biased belief updating, I conducted three pre-registered studies covering different controversial political issues. The main hypothesis was that cognitively devaluing new information hinders belief updating. Support for this hypothesis was found in only one of the three issues. The only factor that consistently influenced belief updating across issues was the discrepancy between prior beliefs and new information. These results suggest that usually people do use evidence to correct their beliefs, but may refuse to do so if doubts about its generalizability arise.

Implementation Methods and Research for a Post-truth World with Growing Inequities.

The purpose of this article is to consider the changing context for implementation research and practice and new approaches which might now be more relevant for some implementation objectives. Factors that hindered implementation of evidence-based practices before the COVID-19 pandemic was an anti-science culture, strengthened by different media and appeals to emotion and identity. The article questions how effective are the rational-cognitive and individual models of change that frequency informs our research and practice. It describes challenges we face and considers methods we could use that might be more effective, including research-informed narrative methods, participatory research and practice, especially with culturally and linguistically diverse peoples, and adaptive implementation.

Program development for leaders in the post-truth era: Arts-based creative leadership communication program.

Developments in media and communication technologies welcomed a new era, defined as post-truth, implying a general distancing from truth, where fake or speculative messages can be instantly shared by a vast audience. In this era, we need leaders with strong emotional and social skills to create a positive and ethical impact in society. In this study, due to the requirements of the Post-Truth Era which necessitates a new approach to leadership development, an arts-based learning intervention entitled Arts-Based Creative Leadership Communication Program is designed for leaders with three main objectives to increase, firstly, their creative communication skills; secondly, healing effect of arts for their resilience; and, thirdly, their social sensitivity through arts. After the design and implementation of this program, its targeted effects on the participants were analyzed. Results indicated that all of the expected outcomes were achieved successfully. The highest development was seen in the healing effect, while change in social sensitivity appeared as the lowest. Emotional skills as non-verbal communication element was developed more than social skills. Meanwhile, the emergence of the pandemic with its digital transformation process increased the effects of the program. To sum up, the program was found successful for the leaders in the Post-Truth Era.

Theorising post-truth in the COVID era.

The focus of this article is on the impacts of COVID-19 related manifestations of post-truth in educational settings in Australia. Within this context, there has been a reorientation of how wellbeing and academic achievement within schools reflect on broader trends within the general public, at local, state and national scales. Individual and communal experiences of adversity have been significantly impacted by phenomena associated with post-truth, particularly misinformation, a climate of anti-intellectualism, as well as fragmented socio-cultural cohesion. In the first section I explore these trends by providing an overview of how post-truth has been construed in Australian contexts, before moving to consider how engagements with post-truth have been shaped by the pandemic. Second, I analyse the close link between educational concerns that emerged from the pandemic era, and the circumstances that have supported the emergence of post-truth. Particular attention will be paid to debates over 'learning loss' and the place of teachers within Australian communities as a fulcrum for generating cultural capital and social cohesion. In the final section I consider what lessons these experiences have for education, as a way of cultivating learning communities that are oriented towards generating critical and digital literacy skills.

The moral psychology of misinformation: Why we excuse dishonesty in a post-truth world.

Commentators say we have entered a "post-truth" era. As political lies and "fake news" flourish, citizens appear not only to believe misinformation, but also to condone misinformation they do not believe. The present article reviews recent research on three psychological factors that encourage people to condone misinformation: partisanship, imagination, and repetition. Each factor relates to a hallmark of "post-truth" society: political polarization, leaders who push "alterative facts," and technology that amplifies disinformation. By lowering moral standards, convincing people that a lie's "gist" is true, or dulling affective reactions, these factors not only reduce moral condemnation of misinformation, but can also amplify partisan disagreement. We discuss implications for reducing the spread of misinformation.

The socio-psychological predictors of support for post-truth collective action.

Politics in the current era are replete with unreliable media stories which lack evidence, sometimes disparagingly dubbed "fake news". A survey on a sample of Muslims in Indonesia (N = 518) in this work found that participants' endorsement of collective action in of support issues with little to no empirical evidence (i.e., post-truth collective action) increased as a function of their belief in fake news and prejudice against the outgroup (i.e., non-Muslims). Belief in fake news stemmed from participants' generic and specific conspiratorial thinking, whereas prejudice was positively predicted by relative Muslim prototypicality, denoting how much Muslims in Indonesia view that their group is more representative than non-Muslims of the superordinate Indonesian identity that encompasses both groups. Additionally, our findings revealed that generic conspiratorial thinking and relative Muslim prototypicality were positively predicted by collective narcissism, which in turn spurred participants' support for collective action by augmenting belief in fake news.

Poly-truth, or the limits of pluralism: Popular debates on conspiracy theories in a post-truth era.

Conspiracy theories are central to "post-truth" discussions. Official knowledge, backed by science, politics, and media, is distrusted by various people resorting to alternative (conspiratorial) explanations. While elite commentators lament the rise of such "untruths," we know little of people's everyday opinions on this topic, despite their societal ramifications. We therefore performed a qualitative content analysis of 522 comments under a Dutch newspaper article on conspiracy theories to study how ordinary people discuss post-truth matters. We found four main points of controversy: "habitus of distrust"; "who to involve in public debates"; "which ways of knowing to allow"; and "what is at stake?" The diverging opinions outline the limits of pluralism in a post-truth era, revealing tensions between technocratic and democratic ideals in society. We show that popular opinions on conspiracy theories embody more complexity and nuance than elite conceptions of post-truth allow for: they lay bare the multiple sociological dimensions of poly-truth.

Crisis of Authority: The Truth of Post-Truth.

This article is a critique of the notion of post-truth. Drawing on the work of Hannah Arendt, I argue that the epistemological crisis suggested by the notion of post-truth is epiphenomenal to a more general crisis of authority, a crisis that is poorly understood in the literature. I also argue that revisiting Arendt's account of authority can help us elucidate the vexed dynamics of authority in modern society, as well as the dynamics behind its current crisis. The post-truth situation is a loss of authority that is political before it presents as epistemological. Effectively addressing this situation, I conclude, is a much more challenging and complex proposition than what is suggested in the literature on post-truth.

Emotional Information in News Reporting on Audience Cognitive Processing in the Age of Posttruth: An Electroencephalogram and Functional Connectivity Approach.

The purpose of the present study is to explore how the emotionalized expression of news content in the posttruth era affects the cognitive processing of the audiences. One news that was text-written with two different expression types (emotional expression vs. neutral expression) was adopted as an experiment material in the study, and changes in cortical activity during news reporting reading tasks were examined with electroencephalograms, sampled from nine sites and four channels and analyzed with weighted phase lag index (wPLI) based on brain functional connectivity (FC) method. The results show that emotional discourses caused a stronger cortical brain activity and more robust brain FC (beta oscillations); besides, reading emotionalized expression consumed more attention resources but fewer cognitive resources, which may impede further rational thinking of the audiences.

Defining Online Hating and Online Haters.

According to a view widely held in the media and in public discourse more generally, online hating is a social problem on a global scale. However, thus far there has been little scientific literature on the subject, and, to our best knowledge, there is even no established scholarly definition of online hating and online haters in the first place. The purpose of this manuscript is to provide a new perspective on online hating by, first, distinguishing online hating from the phenomena it is often confused with, such as trolling, cyberstalking, and online hate speech, and, second, by proposing an operational definition of online hating and online haters based on ethnographic interviews and surveys of the existing scholarly literature.

Is evaluation obsolete in a post-truth world?

The contemporary post-truth phenomenon is characterised by denial of facts and tolerance of politicians' lies. It has enhanced the appeal of authoritarian and nationalist leaders as a populist reaction to policy failures. While emerging market countries hugely benefited from globalization, the hourly wages of working people in high-income countries have stagnated while inequality has surged, and environmental stresses have escalated. Post-truth dispositions are distorting decision making in the public sphere and they have increased public distrust of knowledge professionals. This is likely to aggravate the very problems that gave rise to the post-truth phenomenon. Evaluation can help reverse the trends that underlie voters' anxieties, amplification of tribal prejudices and appeals to national pride through sound advice, transparency and public education. This will require new evaluation policy directions. Evaluation internationalization, diversification, democratization and professionalization will have to take place simultaneously.
