What does the French public consider to be a conflict of interest for medical researcher?
While institutional conflicts of interest (COIs) are widely studied, public perception is often ignored. Based on a December 2021 survey of 2,022 French citizens, this study identifies three distinct public viewpoints on COIs for medical researchers:
- Financial: Only monetary gain matters.
- Ivory Tower: Any relationship with economic, political, or media actors is a COI.
- Undecided: Uncertainty about what qualifies.
These profiles correlate significantly with respondents' social backgrounds and their attitudes toward science, politics, and healthcare.
Project Nonprobability Sample Inference: Fieldwork Report
Probability‑based surveys (PS) face increasing pressure due to high costs and low responserates. At the same time, nonprobability‑based surveys (NPS) which are presumably cheaper and allow for faster data collection become more and more popular. The Project “Nonprobability Sample Inference” (NOSI) evaluates to which extent NPS may serve as aviable alternative to PS in labor market research by comparing one PS to four NPS collected by different providers. This report provides a brief overview of data collection processes, data quality, and costs of these overall five surveys. The PS involved a 2 × 2 experiment on using incentives and reminders for recruitment.

Predictors of COVID-19 vaccine acceptance across time and countries
Analyzing 25 national samples across 12 countries (N = 25,334), this study identifies male sex, worry about the virus, and trust in medical and scientific experts as the most consistent predictors of COVID-19 vaccine acceptance. Because public trust rests heavily on the scientific and medical community, the authors suggest that future vaccination campaigns should center on these experts to maximize uptake.
Intergenerational mobility and preferences for redistribution
Using data from five countries (France, Italy, Sweden, UK, and US), this study investigates how beliefs about social mobility affect preferences for redistribution. It finds that Americans are more optimistic about mobility than Europeans, and exposing individuals to pessimistic mobility data increases support for opportunity-focused policies. However, reactions are deeply polarized: pessimistic information drives left-wing respondents to demand more redistribution, while right-wing respondents remain unmoved due to a fundamental distrust in government solutions.
Immigration and redistribution
Through large-scale surveys and experiments across six countries, this study reveals that natives significantly overestimate the number and negative socioeconomic characteristics of immigrants. Merely priming respondents to think about immigration reduces their support for redistribution; furthermore, while hard facts fail to counter this bias, narrative anecdotes about "hard-working" immigrants prove more effective at shifting public views.
Political information behavior: conversations and traditional media are ahead
Beauty Action: The influence of habitus on the processing of the body
Using an online survey and structural equation modeling, this study examines how social dimensions, media consumption, and personal values influence how individuals control their physical appearance. The interdisciplinary framework integrates Bourdieu’s habitus, Gerbner’s cultivation thesis, and Schwartz values to quantify the underlying drivers behind everyday beauty practices and physical attractiveness.

Politische Online-Partizipation und soziale Ungleichheit
Using univariate and bivariate data from an online survey, this study examines political online participation on civic engagement platforms. The analysis focuses on differences between genders and between participants versus non-participants, while integrating gender-stereotypical attitudes ("doing gender") where theoretically relevant.
How does the population in Germany get information about the coronavirus?
Based on a representative survey of German adults (N = 1,107) in June 2020, this report investigates how the public navigated the massive influx of COVID-19 information and misinformation during the transition to the pandemic's easing phase. It examines shifts in information-seeking behavior since March 2020, focusing on preferred communication channels, the handling of misinformation, and evolving risk perceptions across different demographic groups.
Epistemic change and diverging information: How do prior epistemic beliefs affect the efficacy of short-term interventions?
Based on a preregistered study (N = 509), this research examines how different types of conflicting (diverging) information induce epistemic doubt to change individuals' beliefs about knowledge. The results reveal that diverging information successfully advanced topic-specific beliefs—but not domain-general ones—particularly for individuals who started with naive prior beliefs. Conversely, these interventions had detrimental effects on participants who already held advanced prior beliefs, highlighting the critical role pre-existing mindsets play in epistemic development.
Is it me or you? How Reactions to abusive supervision are shaped by leader behaviour and follower perceptions
Using two experimental vignette studies and a cross-sectional field study, this research examines how followers react (via exit, voice, loyalty, or neglect) to varying degrees of abusive leadership. It demonstrates that followers' perceptions of abuse partially mediate the link between actual leader behavior and subsequent reactions, confirming that responses are rooted in real behavior rather than just subjective bias. Additionally, follower attributions—such as leader intentionality or control—moderate these outcomes, displaying stronger effects in real-world settings where behavioral cues are more ambiguous.
Does thinking of myself as leader make me want to lead? The role of congruence in self-theories and implicit leadership theories in motivation to lead
Surveying 497 individuals across two time points, this study explores how the alignment between a person's view of leaders in general (implicit leadership theories) and their view of themselves (implicit self-theories) impacts leadership self-efficacy and motivation to lead. The findings reveal that high-level congruence in the dimensions of dynamism and integrity boosts leadership self-efficacy, as does perceiving oneself as ranking higher than average leaders in cleverness, dynamism, and integrity. Ultimately, leadership self-efficacy acts as a key mediator, translating these aligned or favorable self-perceptions into a stronger overall motivation to lead.
Validation of a standardized donor health questionnaire across substances of human origin
Evaluating a standardized Donor Health Questionnaire (DHQ) developed by the TRANSPOSE project, this study surveyed representative samples in Germany and Austria (N = 6,761) to test comprehension and honesty. The findings indicate that the DHQ is well-understood and yields high self-reported honesty across various structural layouts, though administering the questionnaire online resulted in a more favorable participant mood than the printed version.
Importance and potential impact of efficient crisis communication
Grounded in Kury’s accountability model and Weiner’s attribution theory, this study by Franziska Hoberg examines how companies can repair trust and mitigate mistrust following an integrity-based crisis. The research demonstrates that organizations can effectively rebuild trust through two communicative forms of accountability—admission and action—underscoring the high practical relevance of efficient crisis communication.
Individual differences and changes in subjective wellbeing durng the early stages of the COVID-19 pandemic
Tracking 979 individuals in Germany across four time points from December 2019 to May 2020, this study examines how the COVID-19 pandemic affected subjective wellbeing, stress appraisals, and coping strategies. While average wellbeing remained stable initially, it significantly declined between March and May 2020. Although specific coping mechanisms and stress appraisals strongly correlated with individual differences in life satisfaction and affect, their overall impact on longitudinal changes in wellbeing was unexpectedly small. Ultimately, the findings underscore the pandemic's psychological toll, suggesting that practitioners focus on enhancing clients' functional stress appraisals and adaptive coping strategies.
Big five traist as predictors of perceived stressfulness of the COVID-19 pandemic
Short Summary:Tracking 588 full-time employees in Germany over six months, this study investigates how Big Five personality traits predicted perceived stress trajectories during the COVID-19 pandemic. While average pandemic stress steadily declined between April and September 2020, individual traits significantly moderated these experiences: emotional stability was associated with lower overall stress, whereas extraversion predicted higher overall stress. Additionally, extraverted individuals exhibited distinct fluctuations, experiencing an increase in stress during the initial lockdown and easing period (April to July), followed by a pronounced decline over the summer vacation months.
Too afraid to travel? Development of a Pandemic (COVID-19) Anxiety Travel Scale (PATS)
Developed across two large online studies in the US and Denmark (N = 2,180; N = 2,062), this paper introduces the Pandemic (COVID-19) Anxiety Travel Scale (PATS) to measure intra-personal anxiety in travelers. Study 1 establishes a concise 5-item scale structure, while Study 2 confirms its reliability and validates it against related constructs like xenophobia and prevention focus. Ultimately, the authors present PATS as a versatile tool applicable to both the COVID-19 crisis and future pandemic-induced travel behavior research.
Climate Change Concerns and
Perceived Intergenerational Mobility
Drawing on survey data from the UK, Germany, and Sweden, this study investigates how climate change concerns relate to perceptions of intergenerational mobility. It finds that individuals who feel climate change threatens their daily lives or future opportunities are more likely to report being downwardly mobile, particularly regarding broader life evaluations rather than strict socioeconomic terms. While this relationship is strongest in the UK and weakest in Sweden, it varies little across birth cohorts but shows notable differences by gender. Ultimately, these findings reveal that environmental anxieties deeply shape views on intergenerational fairness, offering key insights for public communication strategies.
NEWCOMERS European citizen survey on energy transition and energy communities
Based on a large-scale citizen survey conducted across nine European countries (N = 13,499), this report evaluates public perceptions, awareness, and willingness to engage in clean energy communities. The dataset captures the socioeconomic and psychological characteristics of European citizens alongside initial descriptive findings regarding local renewable energy transitions. Ultimately, the accompanying data report validates the study's representativeness and outlines methodologies for utilizing and accessing the underlying dataset.
The Long-Lasting Effects of Experiencing Communism on Attitudes toward Financial Markets
Using novel survey, bank, and broker data, this study demonstrates that exposure to anti-capitalist ideology exerts a lasting influence on capital market attitudes and stock market participation. Decades after German reunification, East Germans continue to invest significantly less in stocks than West Germans, though these effects depend heavily on personal experiences under communism. Individuals with positive memories of life in the German Democratic Republic (GDR) show the strongest aversion to capital markets, whereas those who faced negative conditions—such as environmental pollution or a lack of Western media—exhibit the opposite trend.
Uncomfortable trade-offs in plant protection – public perceptions of chemical and biotechnology options
Through two online studies conducted in German-speaking Switzerland (N = 965; N = 1,061), this research investigates consumer acceptance and perceived naturalness of plant protection products and breeding techniques for managing potato blight. The first study shows that cisgenic modification and genome editing are rated similarly to both natural and synthetic fungicides, while the second study reveals that specific fungicide framing (natural vs. synthetic, named vs. unnamed) significantly impacts consumer associations and acceptance. Notably, widely accepted traditional mutagenesis was rated similarly to newer breeding methods currently restricted by EU regulations, offering key insights for decision-makers evaluating agricultural trade-offs.
