Coastal bathing generates substantial welfare benefits but also exposes recreationists to low-probability, high-salience microbial risks (e.g., E. coli, enterococci, Vibrio, cyanobacteria) that are largely invisible at the point of decision-making. Under climate change, pathogen occurrence and closures are expected to become more frequent, increasing the policy importance of monitoring and credible risk communication under the EU Bathing Water Directive. This talk presents preliminary evidence from a three-wave randomized panel study of users of the Gulf of Gdańsk and the Vistula Lagoon (Poland), combining stated- and revealed-preference data to test whether pathogen-risk information shifts knowledge, preferences, and recreation demand. In Wave 1 we identify “active users” from a large stratified national sample and establish baseline preferences and trip behaviour. In Wave 2, the same respondents are randomly assigned to receive either no additional information or increasingly detailed pathogen-risk scripts, and then complete repeated discrete choice experiments on beach-site selection and monitoring attributes. Approximately one year later, Wave 3 measures longer-run outcomes, elicits policy support in an advisory-referendum DCE for programmes that combine risk reduction and higher-frequency monitoring, and repeats a travel-cost module capturing seaside trips and beach outings. The emerging pattern is that information increases knowledge and selectively shifts preferences and choices toward risk-relevant attributes, with corresponding demand-side responses. I then connect these findings to a practical benefit–cost perspective: because valuations and behavioural responses are information-dependent, "uninformed" welfare estimates used in appraisal may understate the benefits of monitoring/disclosure. Information campaigns are a scalable complement—rather than a substitute—to monitoring and mitigation.

Online content moderation shapes what billions of people can say and see, yet the human judgments that train and evaluate moderation systems are themselves contested. Drawing on a pre-registered cross-national conjoint experiment with 19,172 respondents across 11 countries, we analyze over 150,000 moderation judgments of toxic social media posts. We find robust evidence of myside bias: people are substantially more likely to classify speech as hateful and to support sanctions against it when the attacked shares their position on the contested issue at hand. This pattern holds across countries, political camps, topics, and speech types, and is larger in magnitude than effects of gender, ideology, or ethnic identity. These results reveal a fundamental challenge for content moderation: systematic disagreement in moderation judgments is tied also to the content of beliefs, not only to fixed annotator characteristics. This means that standard bias-correction approaches - which adjust for stable demographic or partisan attributes - cannot resolve the underlying disagreement, posing a structural challenge for the governance of automated enforcement in polarized environments.

Seminar chaired by Francesca Papa

Despite decades of organisational diversity initiatives, selection and promotion processes for leadership positions continue to produce inequitable outcomes. Traditional interventions targeting individual attitudes, such as unconscious bias training, show limited sustained effects on actual selection decisions. This suggests that modifying individual cognition alone is insufficient when environmental factors, such as time pressure, resourcing constraints, and the flexibility to construct post-hoc justifications for decisions, shape selection behaviour. An alternative approach focuses on redesigning decision-making environments (or changing the choice architecture) within selection processes, rather than attempting to change individuals' attitudes.

This scoping review systematically maps 37 empirical studies examining choice architecture interventions applied across the leadership selection pipeline. Following Joanna Briggs Institute methodology and PRISMA-ScR guidelines, studies were synthesised using two complementary behavioural science frameworks: the COM-B Model, to identify the main influences on behaviour (capability, opportunity, and motivation), and Münscher et al.'s (2016) taxonomy, to categorise the choice architecture techniques employed.

Three principal findings emerge. First, interventions constraining assessor discretion, particularly pre-commitment to evaluation criteria and accountability mechanisms, produced more consistently equitable selection behaviour than information-based approaches alone. Second, identity-concealed framing emphasising assessment quality outperformed identity-conscious framing emphasising diversity goals. Third, a critical conversion problem was identified, whereby interventions effective at earlier selection stages frequently failed to translate into hiring or promotion outcomes, indicating that integrated cross-stage approaches are necessary. Findings provide a framework for selection practitioners, identifying which techniques are effective, for whom, and under what conditions, while highlighting critical gaps in the evidence base.

Abstract:

Water scarcity is expected to worsen in the future across the globe, and Europe is no exception. This is driven by a combination of population growth, climate change, socio-economic factors, and changing consumption patterns. While water companies should minimize water loss (e.g., leakage) by investing in resilient infrastructure, customer-side interventions to reduce water demand are equally important. The toolkit water companies use to reduce residential households’ water demand includes, for example, financial instruments such as rising block tariffs, technological instruments such as smart meters, and behavioural instruments such as making the negative environmental implications of abundant water use salient in real time or comparing a household’s water consumption to that of their neighbours.

The presentation discusses two large-scale natural field experiments conducted with Thames Water (one of the largest utilities in the UK) to improve residential water use. It looks at the impact of behavioural and technological instruments on water demand reduction.

We address four central questions:

1. How do we engage customers to complete online water audits (digital assessments of household water usage)?
2. Do these audits impact household water consumption?
3. Does nudging increase household engagement with online gamification platforms?
4. Do gamified incentives impact household water consumption?

LSE profile page

Abstract:

Behavioural science has made important strides in recognising the lack of diversity in its samples. Yet, the question arises: is behavioural science in the process of updating its definition of sample diversity? In this talk, I will reflect on the perils and opportunities of diversity classifications, emphasizing the need to reconsider how we study diverse populations. The discussion will focus on two areas. First, I outline ways to rethink how we conceptualise and measure sample diversity, including approaches that capture both between-country and within-country heterogeneity –an issue central to designing inclusive, evidence-based policy. Second, I examine emerging methodological practices that can both increase and constrain diversity, introducing the idea of an illusion of generalisability. While oversampling rural demographics and employing nationally representative surveys can be promising ways forward, I will discuss research innovations needed to address inclusion more fully. The talk concludes with reflections on research practices that can support more equitable and globally relevant behavioural insights.

Abstract:

Exposure to economic inequality is widely thought to erode subjective well-being and mental health, with important societal implications. However, existing studies face reproducibility issues, and theory suggests that inequality may matter primarily in disadvantaged contexts. I will present a meta-analysis of 168 studies using multilevel data (11,389,871 participants across 38,335 geographical units). Contrary to common narratives, individuals living in more unequal areas did not, on average, report lower subjective well-being. Moreover, although inequality initially appeared to be associated with poorer mental health, the association became null after correcting for publication bias. Further analyses suggested a more complex pattern: Inequality was negatively associated with mental health in low-income samples (but not in high-income samples) and negatively associated with subjective well-being in high-inflation contexts (with the association reversing in low-inflation contexts). We replicated these findings using Gallup World Poll data (up to 2 million participants). Overall, these results suggest that inequality may be better understood as a catalyst that amplifies other determinants of health, such as poverty and inflation, rather than as a direct, general cause of lower subjective well-being or poorer mental health. The presentation will close with brief policy implications.

Abstract:

Advanced economies are undergoing a profound demographic transition characterized by population aging and declining fertility. This shift, combined with rising life expectancy, poses significant economic challenges that could be mitigated by higher inflows of migrants. Yet, public opposition to immigration remains strong. In this study, we use a survey experiment to examine how individuals perceive the economic trade-offs associated with immigration under alternative policy scenarios. Respondents are presented with multiple future immigration policies, each differing in the scale of inflows and their projected economic impacts on destination countries. We experimentally vary the type of economic information provided: one group receives information on the impact of immigration policies on aggregate income (per-capita GDP), another on individual income, while a control group receives no economic information. We then measure support for these different policies - with varying degrees of openness - as well as for two organizations—one assisting migrants in their countries of origin and the other in host countries. The experiment is implemented in three European countries.

Abstract:

Citizen assemblies are an increasingly popular instrument. However, there are only few studies that evaluate their legitimacy and effectiveness. The current project examined two research questions based on field-experimental data from a citizen assembly on the Covid-19 crisis in Austria. First, are citizen assemblies representative of the population in terms of personality characteristics, and are invitation letters a suitable measure to improve representativeness in respect to those personality characteristics? Second, does the participation in a citizen assembly reduce affective polarization?

The sample to test our research questions consists of 14.999 citizens who received one of three different invitation letters from the national statistics office. 716 citizens agreed to participate and were randomly allocated to a participation and a waiting-list (i.e. control) group. They all filled in several surveys. During the same period, 2603 citizens were surveyed to assess the prevalence of personality characteristics in the population.

Concerning our first research question, results show that participants invited with a standard letter are indeed not representative of the population in terms of an important trait: Locus of control. However, if invitation letters emphasize the importance of inclusiveness of all voices compared to the requirement to bring own ideas, an increase in the representativeness of the assembly concerning locus of control is achieved.

Concerning the second research question, results show that affective polarization was significantly lower among the participation group compared to citizens on the waiting list at all survey assessment time points, with no evidence of further reduction following the assembly. Thus, the groups' level of polarization differed even before the assembly started, but the participation itself had no effect.

Overall, our results show that more evaluations and, based on that, adjustments of the method of the citizen assembly are needed to justify the current popular application.

Speaker: Prof. Cameron Brick (University of Amsterdam)

Cameron Brick is Assistant Professor of Social Psychology at the University of Amsterdam, specializing in climate change and pro-environmental behavior. His research focuses on the gap between environmental attitudes, intentions, and actual high-impact behaviors, using survey experiments, behavioral data, and cross-national studies. He co-leads projects on plastics, fast fashion, activism, and citizen science, and his recent work calls for an impact-focused approach that measures behaviors and environmental impacts more directly rather than relying on intentions or vague self-reports.

Personal website

Abstract:

Policymakers face a persistent challenge: strong public support for climate action does not reliably translate into the behaviors or political choices that reduce emissions. Social scientists have often treated environmental attitudes and intentions as adequate proxies for action, but recent evidence shows attitudes and intentions are only weakly associated with objective outcomes such as energy use, mobility, or consumption.

This talk will outline an “impact-focused approach” to studying climate behavior, which distinguishes mental properties (concern, attitudes, intentions) from physical outcomes (emissions, biodiversity, collective action). I will present findings where self-reported “eco-behaviors” correlated with higher emissions, illustrating how reliance on intentions can obscure real effects. Demographics like income and context like infrastructure and social visibility may explain behavior better than attitudes and intentions.

This misalignment is an implementation barrier: assuming intentions will translate into action risks policies underperforming at scale. Effective evaluation should prioritize direct behavioral or impact-based measures, so that research and policy align on outcomes rather than intentions. Such an approach reveals both the limits of behavioral influence strategies and the opportunities for structural change.

She has held visiting scholarships at Princeton University and Harvard Business School, and has collaborated on applied projects with organisations including NATO StratCom and the World Health Organization. Her work combines experimental research with policy-oriented applications on digital platforms, democratic resilience, and emerging technologies.

Abstract:

Misinformation poses a growing threat to European societies by eroding trust in democratic institutions, fuelling polarisation, and undermining public health and climate action. While much policy attention has centred on fact-checking and accuracy nudges, this talk presents research showing that these approaches overlook a crucial factor: people rarely evaluate information in isolation. Instead, they rely on social and contextual cues - such as consensus signals, engagement metrics, or the subjective credibility of information sources - which can make misleading claims appear trustworthy.

Drawing on experimental studies conducted during my doctoral research at the University of Cambridge, I show how social influence processes increase susceptibility to misinformation and assess the effectiveness of psychological inoculation (“prebunking”) interventions. Inoculation - so-called “psychological vaccines” - strengthen resilience, yet even inoculated individuals remain vulnerable in socially mediated environments. This highlights the need for interventions that are not only cognitively robust but also socially embedded and scalable.

For policymakers, the findings suggest a shift from reactive fact-checking toward proactive resilience strategies. The talk concludes by reflecting on how these insights can inform European approaches to strengthening resilience - across digital literacy, informed democratic participation, and the design of the online information environment. As a practical case example, I introduce Solomon’s Secret, a gamified inoculation tool that demonstrates how interactive approaches can prepare young audiences to resist manipulation in the digital age.

Abstract:

Human behaviour is central to the green transition: achieving a sustainable, low-carbon economy requires behavioural changes from individuals, businesses, and governments. Governments play a pivotal role in driving these changes and fostering sustainable behaviour across the economy. This talk will present a recent OECD policy paper identifying six key trends illustrating how behavioural science is shaping public policy to accelerate the green transition. Drawing on over 100 case studies, the paper provides policymakers with a practical roadmap to integrate behavioural science into environmental policy. The trends include embedding behavioural science throughout the policy cycle, assessing public acceptability of green reforms, enhancing citizen participation in environmental policies, strengthening resilience against climate misinformation, and increasing demand for sustainable goods and services.

Abstract:

With the development of generative machine learning techniques in the 2010s, and rapid acceleration of these efforts with the success of large language modelling, it is increasingly easy to generate "synthetic samples"—data that appears as if sampled from the real world, but which are generated by statistical models. How should we understand what these models are doing? What aspects of (social scientific) research can these models improve? And what are the inherent limitations of using generative models trained on finite data samples? In this talk, I situate how synthetic data relates to other forms of data we commonly use in the social sciences and show when it is likely (not) to be useful. I illustrate these claims by presenting a method for training deep, generative neural networks on tabular data. In particular, I show how these models can synthesise realistic looking, but entirely novel, survey data.

Abstract:

The Consumer Duty is a landmark regulatory development for the UK financial sector, introduced by the Financial Conduct Authority in July 2023. In its objective to improve outcomes for consumers, insights from behavioural science have shaped the regulation’s development and implementation.

Findings from behavioural science have been explicitly embedded within the regulatory guidance, and regulated firms are expected to proactively consider evidence and research from behavioural science in how they operate and engage with their customers in order to be compliant.

This talk will discuss the successes and challenges of explicitly embedding a behaviourally-informed approach into public policy and regulation, using this novel and innovative case study. It will also share case studies of experimental and behavioural data science research designed to support the implementation of the Duty in specific policy areas such as consumer investments and retail banking.

It will be of interest to behavioural scientists working in applied settings in other areas of policy/ regulation as well as to academics interested in the theoretical and practical considerations of the intersection of behavioural science and public policy.

LSE profile page

Abstract:

Buzzwords abound in behavioural public policy and are used to label various and varied conceptual policy frameworks in the field. The first and most famous of these buzzwords is ‘nudge’, which in its original manifestation encapsulated a coherent, if limited, perspective. However, instead of acknowledging the limitations of the approach, which several alternative frameworks were developed to address, the advocates of nudge and those with little expertise in the field widened the parameters of the framework to an extent that its original meaning was largely lost.

In this presentation, Prof. Oliver details these developments and proposes that the buzzwords that are often loosely attached to behavioural public policy interventions – e.g. nudges, nudge-plus, boosts, shoves and budges – be dropped. Instead, it is suggested that academics, practitioners, policy makers and the general public reflect more deeply on the type of society in which we collectively wish to live, and assess each behavioural public policy intervention on its own terms to discern whether it is congruent with our societal values.

Abstract:

Air travel generates disproportionate greenhouse gas emissions. In the absence of supply-side options to reduce emissions, there is interest in demand-side measures, which include providing emissions information at the point-of-sale. We deployed a pre-registered experiment to test whether emissions labelling shifts consumers towards lower-emission flights and whether consumers understand the labels currently in use. Participants completed two tasks on a realistic travel website, one where they were asked to purchase holiday flights as they normally would and another where they were incentivised to choose the lowest-emission flight for someone else. We found that while labels produce a modest shift towards flights with lower relative emissions on a given route, they also lead some participants to choose higher-emitting flights. This happens because the labels “greenwash” long-haul flights with large reductions in relative emissions. Consistent with this, the labels generate confusion: two-in-three people misinterpret the reference point for relative labels and few correctly identify the factors that contribute to label calculations. We conclude that current emissions labels are unlikely to reduce aviation emissions or to inform consumers about the impact of their travel choices.

Abstract:

In many public policy areas, randomized policy experiments can greatly contribute to our knowledge of the effects of policies and can thus help to improve public policy. However, policy experiments are not very common. This paper studies whether a lack of appreciation for policy experiments among voters may be the reason for this. Collecting survey data representative of the Dutch electorate, we find clear evidence contradicting this view. Voters strongly support policy experimentation and particularly so when they do not hold a strong opinion about the policy. In a subsequent survey experiment among a selected group of Dutch politicians, we find that politicians conform their expressed opinion about policy experiments to what we tell them the actual opinion of voters is.

Abstract:

We report the results of a field experiment targeting discrimination towards Venezuelan migrants in Colombia. We provide a large and representative sample of young adult residents in Bogota with a sequence of short radio podcast episodes, presenting daily interaction between Colombians and Venezuelans. We randomly split participants, stratified by gender and SES, in two groups: one receiving links to the podcast by WhatsApp (Treated), the other one being asked to fill a sequence of surveys, identical to the ones filled by participants in the treated condition (Control). We evaluate the impact of the intervention collecting data before the intervention starts (Baseline survey), immediately after the intervention ends (Final survey) and weeks later (Tracking survey). In the Baseline survey, participants (all of them untreated) were randomly assigned to one condition in a survey experiment. The experiment had two vignettes, describing job applications and fast-food restaurant scenarios. The factorial design manipulates the nationality (Venezuelan or Colombian) and sex (changing names) of the vignette’s main character. Our differences-in-differences analysis strongly suggests that discrimination towards Venezuelan migrants is rampant among young residents in Bogota. In the Baseline, participants dismiss Venezuelan applicants to a fictitious job and refuse to serve a Venezuelan client entering a fast-food restaurant. Behavior is consistent with both preference- based and systemic discrimination. Interestingly, we find no trace of intersectional discrimination, as male and female migrants are discriminated equally. The Final and Tracking surveys show that the intervention works, as it significantly and substantially changes the attitudes and behavior of young residents towards migrants. Treated participants change their perception of migrants’ work ethic, educational achievements, and likelihood of committing a crime. Mistrust towards migrants is severely reduced, and participants are significantly more open to engage with migrants. Results are largely homogeneous across participants’ sex, political orientation and SES. Most results, but not all, persist weeks after the intervention concluded.

Abstract:

In this talk, Prof. Whitmarsh argues that most of the measures required to reach our climate change targets require at least some degree of behaviour change. And that more broadly, social transformation is required to reach ’net zero’ carbon targets in the coming years. In order to achieve this, we need public engagement and participation in decision-making about what a low-carbon future looks like, and how to reach it. We also need a wide range of measures to change people’s behaviour at home, work and elsewhere. I will present findings from polls and citizens assemblies on public concern about climate change, and support for net zero policies; and from behavioural science research on how to effectively change behaviour to cut emissions.

Abstract:

Economic losses from flooding are increasing around the world, which highlights the need to take measures that limit flood risk. However, many individuals in flood-prone areas do not invest in cost-effective flood risk mitigation measures and do not purchase flood insurance coverage. This has been explained by a variety of behavioural biases. In this talk, I will discuss these biases leading to suboptimal flood preparedness. Moreover, I will present behavioural economic studies that tested policy interventions designed to address these biases. These interventions can help individuals better prepare for future floods, such as nudges and financial incentives provided through insurance policies. Based on these findings, I will offer recommendations for flood risk management policies.

Behavioural Science at the United Nations

The UN Secretary-General released a policy brief on "UN 2.0" which highlights the importance of behavioural science in creating forward thinking culture and as one of five cutting edge skills for the 21st century. This commitment is reaffirmed in the Secretary-General’s 2021 Guidance Note on Behavioural Science and supported by the UN Behavioural Science Group , which brings together over 6,000 colleagues from 70+ UN Entities and 140+ countries.

This session will focus on how behavioural science is being applied in the UN to policy, programming and administration - and where the UN is headed next.

German Federal Chancellery

In this talk we will share initiatives and learnings from this legislative term to further embed expertise from behavioural and social sciences in our governmental processes: we will talk about consultations of draft bills, legal design and the citizen check. We hope to encourage a debate about learning from similar initiatives, such as the dutch Doenvermogentoets.

Speaker: Dr. David De Coninck (KU Leuven)

David De Coninck (PhD) is a postdoctoral researcher and guest professor at the Centre for Sociological Research at KU Leuven (Belgium). His research interests revolve around intergroup relations, with special attention to migrant deservingness, media effects, and intergroup contact. He has published widely on these topics in highly ranked academic journals in various fields.

KU Leuven profile page

Abstract:

I will highlight the development of a new framework that provides a fresh perspective on public preferences regarding migrants, how it can be used to gain further insights into discriminatory behaviour towards migrants, and investigate the extent to which this framework is found in news media coverage of migrants. In the field of social policy, the CARIN criteria (Control, Attitude, Reciprocity, Identity, Need) have been used to assess public preferences with regards to the allocation of welfare benefits to different groups. I will apply these criteria to migrant deservingness: which ‘type’ of migrant does the public feel deserves to settle in a country? The framework of deservingness draws from a variety of academic perspectives, through the integration of multiple research disciplines: e.g. sociology, social policy, migration studies, communication sciences, and political communication. In a current project on the topic, I combine desk research of media content with a mixed-method approach to develop the theoretical framework and to deliver new insights for academia and policy makers: an online survey will gauge public opinion and experimental correspondence tests will be conducted to assess discriminatory behaviours towards migrants. Based on this developed theoretical framework, I formulate recommendations for policy and practice.

sistemaFutura website

Abstract:

In order for climate adaptation policy to be effective, individuals and the institutions in which they are embedded need to take action: from government employees, to businesses, to consumers. Well-intentioned and well-crafted policies that seek to ameliorate the effects of climate risks are wasted if they are not implemented, if people do not comply with them, or if vital feedback on their effects is not gathered and utilised in further policy development. In each of these areas, behavioural science can help.

In this discussion, we share a framework to understand the various ways in which behavioural science can help support climate adaptation policy. Specifically, it employs a behavioural systems analysis, an emerging technique that seeks to drive meaningful behavioural change at both the individual level and the system level. We’ll share a concrete example of climate adaptation among Kenyan pastoralists, and then demonstrate how the framework can be for other multi-level policy challenges

University of Amsterdam profile page

Abstract:

The Trust in the Digital Society Research Priority Area at the University of Amsterdam is an interdisciplinary research effort to better understand trust dynamics in the digital society. Platforms, social media, AI systems, e-commerce systems, search engines, algorithmic recommenders and filtering systems, blockchains, reputation management systems, dating apps and app marketplaces, welfare and predictive policing systems are just a few of those info-communication technologies which either produce new forms of (dis)trust, replace, remediate, or disrupt existing mechanisms of trust formation.

Our project focuses on four major questions:

• What are the new digital infrastructures we increasingly rely on to build trust in our social, political, economic, and interpersonal relations in society?
• What kind of societal trust dynamics emerge by this increased reliance of trust through technology?
• Are these infrastructures trustworthy? And if, as we have every reason to believe, they aren’t,
• What combination of regulation, design, competition, economic incentives, public oversight, and political accountability makes these infrastructures (more) trustworthy?

In this talk UvA researchers will discuss how they operationalized these questions, and what research projects are in the making. The goal of this meeting is to explore building research networks, sharing resource, starting collaborative efforts on empirical, theoretical and legal/policy work.

In particular, we’ll touch upon how social media facilitates the circulation of (dis)trust narratives; what platforms’ trust and safety units are doing; how the emerging EU tech regulation framework can and cannot contribute to the trustworthiness of digital technologies; and how we can better understand the psychological processes of (dis)trust formation in the digital environment.

Abstract:

What are the most effective ways to address climate change? This seminar presents a research paper that extends and applies the marginal value of public funds (MVPF) framework to help answer this question. We examine 96 US environmental policy changes studied over the past 25 years. These policies span subsidies (wind, residential solar, electric and hybrid vehicles, vehicle retirement, appliance rebates, weatherization), nudges (marketing and energy conservation), and revenue raisers (fuel taxes, cap and trade). For each policy, we draw upon quasi-experimental or experimental evaluations of causal effects and translate those estimates into an MVPF. We apply a consistent translation of these behavioral responses into measures of their associated externalities and valuations of those externalities. We also provide a new method for incorporating learning-by-doing spillovers.

The analysis yields three main results:

• First, subsidies for investments that directly displace the dirty production of electricity, such as production tax credits for wind power and subsidies for residential solar panels, have higher MVPFs (generally exceeding 2) than all other subsidies in our sample (with MVPFs generally around 1).
• Second, nudges to reduce energy consumption have large MVPFs, with values above 5, when targeted to regions of the US with a dirty electric grid. By contrast, policies targeting areas with cleaner grids such as California and the Northeast have substantially smaller MVPFs (often below 1), despite larger treatment effects in those areas.
• Third, gas taxes and cap-and-trade policies are highly efficient means of raising revenue (with MVPFs below 0.7) due to the presence of large environmental externalities.

We contrast these conclusions with those derived from more traditional cost per ton metrics used in previous literature.

Abstract:

Addressing the biodiversity crisis requires unprecedented societal transformations within a short time frame. Behavioral science has an important role in informing this transformation, but so far, it has only had a relatively minor role in informing biodiversity conservation strategies. In my talk, I will first discuss how to think about conservation-relevant behavior and its determinants. I will then characterize the typical behavioral science approach to studying conservation-relevant behaviors and pinpoint pertinent limitations and blind spots. I will close by offering suggestions for developing behavior change interventions.

Abstract:

We develop a comprehensive framework to assess policy measures aimed at curbing false news dissemination on social media. A randomized experiment on Twitter during the 2022 U.S. mid-term elections evaluates such policies as priming the awareness of misinformation, fact-checking, confirmation clicks, and prompting careful consideration of content. Priming is the most effective policy in reducing sharing of false news while increasing sharing of true content. A model of sharing decisions, motivated by persuasion, partisan signaling, and reputation concerns, predicts that policies affect sharing through three channels: (i) updating perceived veracity and partisanship of content, (ii) raising the salience of reputation, and (iii) increasing sharing frictions. Structural estimation shows that all policies impact sharing via the salience of reputation and cost of friction. Affecting perceived veracity plays a negligible role as a mechanism in all policies, including fact-checking. The priming intervention performs best in enhancing reputation salience with minimal added friction.

Speaker: Dr. Sophie Attwood (World Resources Institute)

Dr Sophie Attwood is Senior Behavioral Scientist at the World Resources Institute (WRI) and her work focusses on helping people to switch to healthier and more sustainable diets and reduce food waste. Sophie is a Chartered Health Psychologist and Doctor of Behavioral Science from the University of Cambridge. She has researched and published extensively on the science of behavior change for health and sustainability, covering the areas of diet, physical activity, wellbeing, smoking cessation, and alcohol reduction. Her work has featured in a range of international media outlets including Reuters, Forbes, The Guardian, and the World Economic Forum.

Abstract:

Think of the words ‘food waste’, and chances are that your mind conjures up an image of a rotting, mouldy, smelly pile of food, landfill with flies buzzing around it, or a half-eaten plate leftovers.

For those of us working to reduce the amount of food that households waste in the European Union, the fact that this problem is ugly, boring and gross, makes it all the more difficult to create change at the scale we need. We must first overcome implicit negative associations in order to engage consumers, and work hard to correct misperceptions that food waste is only post-consumption scraps, rather than uneaten, edible food. In this presentation, I will review research on consumer perceptions of food waste and how these influence consumer motivations to engage with the issue and take action. Subsequently, I will explore how behavioral science can be applied to change consumer perceptions, presenting a series of studies exploring social norms interventions to make food waste socially unacceptable, and subsequently outline suggestions for how to reframe consumer perceptions of food waste, so that tackling this problem is seen as innovative, creative and altruistic instead.

Abstract:

The proliferation of mis- and disinformation threatens to erode the credibility of public institutions and limit their capacity to implement policies that enhance public well-being. While misinformation represents an urgent global challenge, relatively little research has examined solutions in low- and middle-income countries. We experimentally test the impact of a novel WhatsApp chatbot game intervention in Jordan to boost capacity to identify common misinformation techniques and reduce the likelihood of sharing misleading headlines with others -effectively 'inoculating' them against misinformation. A sample of 2,851 participants was recruited online and randomly assigned to five study arms: (1) comprehensive game-based inoculation that highlighted examples of misinformation and non-misinformation, (2) brief game-based inoculation that highlighted examples of only misinformation, (3) infographics-based inoculation, (4) exposure to placebo infographics unrelated to misinformation, and (5) pure control. To evaluate the impact of our intervention, we assess two main outcomes: (i) ability to accurately discern headlines using misinformation techniques and headlines that do not use misinformation techniques, and (ii) discernment in sharing the two types of headlines. Compared to the control group, the comprehensive version of the game significantly improved discernment of misinformation and reduced likelihood of sharing misleading headlines. A brief version of the game yielded weaker effects on discernment of misinformation and likelihood of sharing misleading headlines. In contrast, exposure to infographics teaching similar techniques or a set of placebo infographics on an unrelated topic showed no significant impacts on discernment of misinformation and sharing intentions. These findings suggest that games can be highly effective mechanisms for inoculating the public against misinformation in the context of a middle-income country in the short term. Future research is also needed to explore the boundary conditions of our findings including assessment of medium- and long-term effects.

Abstract:

Human behavior shapes nearly every aspect of our lives. It affects the success of societies, markets, organizations and individuals. Indeed, many economic and social challenges, such as pandemics, climate change, and energy crises, require behavioral change. In this talk, I will use case studies, mostly from my own research, to show how research in market design and behavioral economics can be used to design mechanisms that align incentives and behavior with underlying goals.

Michael Pahle - Potsdam Institute for Climate Impact Research

Abstract:

National environmental protection policies are coming under pressure despite increasingly dramatic climate realities. At the same time, global cooperation in achieving fast enough emission reduction to fulfil the Paris Agreement is lacking. Knowledge of this lack of international cooperation may further reduce citizens’ willingness to support climate policies at home, potentially leading to a viscious circle of lower ambitions in national politics undermining global commitments. In this context, we present experimental survey evidence from all major EU countries with more than 50,000 participants, investigating links between individual attitudes on climate, moralisation and donation behaviour, and evaluating the effects of an information treatment showing international failure to cooperate. We analyse participants’ preferences for action at the national, EU and global level. We show that many people are committed to spending their own money on reducing emissions, and that this relates strongly to climate policy moralisation. Negative information on global cooperation has no negative effect on peoples’ support for climate policies, offering an optimistic take on future policies. We further explore country differences in attitudes, behaviours and knowledge about climate-related policies.

Abstract:

It is well established that defaults have a strong impact on people’s behaviours – for example the browser that people use on their phone or desktop, and many don’t even know they are being defaulted or how to change it. One potential solution regulators are considering is the use of ‘choice screens’ that prompt people to actively select their preferred default browser instead of it being selected for them by the platform/device manufacturer – and in the EU such choice screens are a requirement under the Digital Markets Act. The aim is to give people more control over the browser they use and ultimately promote greater competition amongst browsers. However, there is little robust evidence to date on the use and design of such choice screens. We undertook a large-scale experiment to test how differently designed choice screens influence people’s choices and levels of satisfaction. Our analysis provides insight into the impact of the design of choice screens and their potential to be effective. We found that certain elements of design – in particular ordering and placement – can significantly influence the choices that people make. People also had clear stated preferences for being shown a choice screen, and being shown more information about the browsers included on it.

Speaker: Prof. Robert Sugden (University of East Anglia)

Robert Sugden is Professor of Economics at the University of East Anglia in the United Kingdom. His research uses a combination of theoretical, experimental and philosophical methods to investigate issues in behavioural economics, normative economics, choice under uncertainty, the foundations of decision and game theory, the methodology of economics, and the evolution of social conventions. His current work aims to reconcile behavioural and normative economics, using principles of opportunity and mutual advantage rather than welfare. This work is synthesised in his recent book The Community of Advantage (Oxford University Press, 2018).

University of East Anglia profile page

Abstract:

Many of the empirical findings of behavioural economics are routinely described as ‘biases’ or ‘errors’ which interpose between individuals’ true preferences and their choices. Behavioural economists’ recommendations about public policy are often justified in terms of their effects on individuals’ welfare, with ‘welfare’ defined as the satisfaction of preferences. The difference from traditional welfare economics is that preferences are not assumed to be reliably revealed in choice, even when individuals have full information about the relevant market. Instead, each individual is implicitly assumed to have latent preferences which would be revealed in her decisions if she had complete information and was not subject to biases or errors attributable to deficiencies of cognitive capacity, attention or self-control.

I will argue that the concept of latent preference lacks psychological foundations and, in consequence, is explanatorily redundant. How far an individual’s decisions are context-dependent is an empirical question, but which contexts induce true preferences is not. In privileging preferences revealed in some contexts over those revealed in others, behavioural economists are being paternalistic while pretending otherwise. I do not claim that public policy should never be paternalistic, but paternalistic recommendations should be made openly. Alternatively, one can take a non-paternalistic approach in which the normative criterion is opportunity rather than preference-satisfaction.

Abstract:

We empirically investigate the ethical implications of human-machine interaction. Specifically, we present the results of three experiments on the influence of machines on people’s judgments and decisions in the moral domain. First, in a vignette experiment, we research the role of transparency for the influence that algorithms exercise on people. We find that subjects are strongly influenced by algorithmic advice across various moral dilemmas and that this influence even persists if subjects are given reasons to doubt the advice’s moral quality. Second, in an incentivized experiment, we test for unintended behavioral effects in human-machine interaction and stress the relevance of an ethically aligned design of this interaction. We observe that subjects’ selfishness is uninfluenced by the presence of a machine corrective but that their selfishness increases if they are supposed to correct a machine’s decision. Third, in another recent vignette study, we study the effect of ChatGPT on users’ moral judgments. We find that our subjects’ answer to the trolley problem is highly influenced by the chatbots inconsistent advice and that this effect is unconscious to a large degree.

Abstract:

Does flexible pay increase the gender wage gap? To answer this question, we analyze the wages of public school teachers in Wisconsin, where a 2011 reform allowed school districts to set teachers’ pay more flexibly and engage in individual negotiations. Using quasi-exogenous variation in the timing of the introduction of flexible pay, driven by the expiration of preexisting collective-bargaining agreements, we show that flexible pay lowered the salaries of women compared with men with the same credentials. This gap is larger for younger teachers and smaller for teachers working under a female principal or superintendent. Survey evidence suggests that the gap is partly driven by women engaging less frequently in negotiations over pay, especially when the counterpart is a man. The gap is unlikely to be driven by observable gender differences in job mobility or teacher ability, although the threat of moving and a high demand for male teachers could exacerbate it. Our results suggest that pay discretion and wage bargaining are important determinants of the gender wage gap and that institutions, such as unions, might help narrow this gap.

Abstract:

The EU has set four priorities that shape the political and policy agenda until 2024. Those include for example, building a climate-neutral, green, fair and social Europe and promoting European interests and values such as global peace, stability, democracy and human rights. For policies to be effective, EU citizens’ support and engagement is essential. We will discuss various experimental evidence showing however, that people often prefer to remain ignorant of the impact their behaviour has on others or the environment. By claiming “I did not know”, people can feel good while being selfish. The research highlights the importance of transparency in communicating the consequences of our actions to others.

Speaker: Prof. Elizabeth Linos (Harvard Kennedy School of Government)

Dr. Elizabeth Linos is the Emma Bloomberg Associate Professor for Public Policy and Management, and Faculty Director of The People Lab at the Harvard Kennedy School of Government. Most of her research deals on how to improve government, by focussing on its people and the services they deliver. Specifically, she uses insights from behavioral science and evidence from public management to consider how to recruit, retain, and support the government workforce, how to reduce administrative burdens that low-income households face when they interact with their government, and how to better integrate evidence-based policymaking into government. Her research has been published in various top academic journals. As the former VP and Head of Research and Evaluation at the BIT in North America, she worked with government agencies in the US and the UK to improve programs using behavioral science and to build capacity around rigorous evaluation. Prior to this role, Dr. Linos worked directly in government as a policy advisor to the Greek Prime Minister, George Papandreou, focussing on social innovation and public sector reform.

Abstract:

Prof. Linos will share insights from her previous research, in particular from "Bottlenecks for Evidence Adoption": Governments increasingly use RCTs to test innovations before scale up. Yet, little is known about whether and how they incorporate the results of the experiments into policy-making. Elizabeth and her co-authors followed up with 67 U.S. city departments which collectively ran 73 RCTs in collaboration with a national Nudge Unit. Compared to most contexts, the barriers to adoption are low. Yet, city departments adopt a nudge treatment in follow-on communication in 27% of cases. As potential determinants of adoption, they considered (i) the strength of the evidence, as determined by the RCT itself, (ii) features of the organization, such as “organizational capacity” of the city and whether the city staff member working on the RCT has been retained, and (iii) the experimental design, such as whether the RCT was implemented as part of pre-existing communication. Their insightful results underline the importance of considering the barriers to evidence adoption, beginning at the stage of experimental design and continuing after the RCT completion.

Speaker: Prof. Natalia Montinari (University of Bologna)

Natalia Montinari received her PhD in Economics and Management in 2011, from the University of Padua (Italy). She was a post-doc at the Max Planck Institute of Economics (Germany, 2011-13) and an Assistant Professor at Lund University (Sweden, 2013-16). Besides her current research, in the past she studied how monetary and non-monetary incentives interact with the heterogeneity of individual preferences. She mainly applies experimental economics methodologies. The results of her research activities have been published in international journals, including European Economic Review, Journal of Risk and Uncertainty, Journal of Law, Economics and Organizations, Experimental Economics, Journal of Economics, Organization and Behavior, Journal of Economic Psychology, and PlosOne.
