Environmental cues can affect food decisions. There is growing evidence that environmental influence how much one consumes. This article demonstrates similarly impact the healthiness of consumers’ choices. Two field studies examined this effect with consumers vending machine foods who were exposed to different posters. In study 1, a health-evoking nature poster compared pleasure-evoking fun fair or no in their visual sight more likely opt for healthy snacks. Consumers also buy snacks when...
Abstract During the onset of COVID-19 pandemic, COVIDiSTRESS Consortium launched an open-access global survey to understand and improve individuals’ experiences related crisis. A year later, we extended this line research by launching a new address dynamic landscape pandemic. This was released with goal addressing diversity, equity, inclusion working over 150 researchers across globe who collected data in 48 languages dialects 137 countries. The resulting cleaned dataset described here...
People across the world and throughout history have gone to great lengths enhance their physical appearance. Evolutionary psychologists ethologists largely attempted explain this phenomenon via mating preferences strategies. Here, we test one of most popular evolutionary hypotheses for beauty-enhancing behaviors, drawn from market parasite stress perspectives, in a large cross-cultural sample. We also other influential non-mutually exclusive theoretical frameworks, biosocial role theory...
One reason consumers buy unsustainable products is that judging the environmental impact of food choices very difficult. This study examines whether using carbon footprint labels to convey relevant information increases tendency choose low-carbon items. In a pre-registered online experiment, 1,126 participants chose between low-CO2 and high-CO2 14 times (e.g., chili sin carne versus con or margarine butter). The two alternatives were either presented without (control), with label...
Romantic love is a near-universal human experience. However, while it transcends cultural boundaries, its intensity varies significantly across individuals and societies. We hypothesize that this variability partly driven by socio-cultural factors, particularly individualism—a orientation prioritizing personal goals over group interests. As individualism continues to rise globally, implications for romantic relationships remain underexplored. Here, we address examining the link between in...

In this study, we tested the validity across two scales addressing conspiratorial thinking that may influence behaviours related to public health and COVID-19 pandemic. Using COVIDiSTRESSII Global Survey data from 12 261 participants, validated 4-item Conspiratorial Thinking Scale 3-item Anti-Expert Sentiment 24 languages dialects were used by at least 100 participants per language. We employed confirmatory factor analysis, measurement invariance test alignment for internal consistency...
Primary stressors are direct outcomes of extreme events (e.g., viruses, floodwater) whereas secondary stem from pre-disaster life circumstances and societal arrangements illness, problematic policies) or inefficient responses to the event. Secondary can cause significant long-term damage people affected but also tractable amenable change. In this study we explored association between stressors, social identity processes, support, perceived stress resilience. Pre-registered analyses data...
The United Nations' sustainable development goals call for a 50 % reduction in global household food waste by 2030, but an accurate measurement method to quantify has yet be developed. In field experiment with 359 households, this study compares standard methods (survey, diary, kitchen caddy) and assesses the barriers measures. Based on our experimental design, we derive minimal estimate of (ground truth) that allows us examine explain differences results these methods. suggest physical is...
In a national sample of 5087 Spaniards, we examine the prevalence 10 specific misperceptions over five separate science and health domains (climate change, 5G technology, genetically modified foods, vaccines, homeopathy). We find that about foods general risks technology are particularly widespread. While partisan affiliation is not strongly associated with any aside from climate two distinct dimensions an anti-elite worldview—anti-expert conspiratorial mindsets—are better overall predictors...
Vaccines are an effective means to reduce the spread of diseases, but they sometimes met with hesitancy that needs be understood.In this study, we analyzed data from a large, cross-country survey conducted between June and August 2021 in 43 countries (N = 15,740) investigate roles trust government science shaping vaccine attitudes willingness vaccinated.Despite significant variability countries, found both forms institutional were associated higher receive COVID-19 vaccine. Furthermore,...
Susceptibility to social influence (SSI) has been reported as a key factor for in online networks (OSNs) such Facebook, Instagram, and Twitter. In four studies, we show that the personality trait of SSI, namely susceptibility normative (SNI), predicts extent which Facebook users comply with behavior others on (e.g., buying, voting, or visiting what other OSN post). Studies 1a 1b, find SSI correlates diverse behaviors, are typical results being affected by influence. Study perceived...
Why do people prefer one particular COVID-19 vaccine over another? We conducted a pre-registered conjoint experiment (n = 5,432) in France, Germany, and Sweden which respondents rated the favorability of chose between pairs hypothetical vaccines. Differences effectiveness prevalence side-effects had largest effects on preferences. Factors with smaller include country origin (respondents are less favorable to vaccines Chinese Russian origin), technology exhibited small preference for mRNA...
Corrective or refutational posts from ordinary users on social media have the potential to improve online information ecosystem. While initial evidence of these corrections is promising, a better understanding effects across different topics, formats, and audiences needed. In three pre-registered experiments (N = 1944 UK, N 2467 Italy, 2210 Germany) where respondents completed post assessment task with false true news various topics (e.g., health, climate change, technology), we find that...
Approximately one-third of all food produced for human consumption is either lost or wasted. Given the central position retailers in supply chain, they have potential to effectively reduce consumer waste by implementing targeted interventions. To do so, however, should target distinct groups. In this research, we use a unique data set comprising grocery shopping customers who loyalty cards, complemented with reports, derive three groups: traditionals, time-constrained, and convenience...
Individuals exposed to dieting-related environmental cues have been repeatedly shown be better able resist tempting food. This especially applies restrained eaters who hold a chronic dieting goal. Thus far, mainly short-term effects of examined and the individuals were typically unaware being influenced. Yet, it is unclear whether can deliberately apply for themselves facilitate pursuit longer-term goal losing weight. The present longitudinal study applied 2 (cue: visually vs. neutral cue) ×...
During theCOVID-19pandemic,manycountries implementedrestrictionsto limit the spread of SARS-CoV-2 virus (e.g. travel restrictions and lockdowns).One path to loosening is do so selectively only for vaccinated individuals by implementing vaccine passports domestically or as a prerequisite international travel).Setting different rules based on people's vaccination statusis howevera contentious issue among health policy experts, government officials, public.
