In the current study, we used functional magnetic resonance imaging to investigate how the brain facilitates social judgments despite evaluatively conflicting information. Participants learned consistent (positive or negative) and ambivalent (positive and negative) person information and were then asked to provide binary judgments of these targets in situations that either resolved conflict by prioritizing a subset of information or not. Self-report, decision time and brain data confirm that integrating contextual information into our evaluations of objects or people allows for nuanced (social) evaluations. The same mixed trait information elicited or failed to elicit evaluative conflict dependent on the situation. Crucially, we provide data suggesting that negative judgments are easier and may be considered the 'default' action when experiencing evaluative conflict: weaker activation in dorsolateral prefrontal cortex during trials of evaluative conflict was related to a greater likelihood of unfavorable judgments, and greater activation was related to more favorable judgments. Since negative outcome consequences are arguably more detrimental and salient, this finding supports the idea that additional regulation and a more active selection process are necessary to override an initial negative response to evaluatively conflicting information.
Om het gebruik van gedragskennis te vergroten en effectief in te zetten is in dit rapport gekeken naar sociaal-psychologische kennis die bij kan dragen aan het stimuleren van rechtmatig gedrag op vijf gebieden: 1. Online seksueel getinte communicatie bij jongeren 2. Voetbalvandalisme 3. Winkeldiefstal door eigen personeel 4. Effectieve digitalisering van geschiloplossing 5. Woonoverlast. De huidige inventarisatie van de beschikbare kennis is bedoeld als wegwijzer voor het stimuleren van beleid dat wettelijk gedrag bevordert en onwettelijk gedrag zo veel mogelijk probeert te voorkomen.
Abstract Europe has faced several crises over recent years, including the COVID-19 pandemic and the war in Ukraine. Additionally, the climate crisis has led to an increase in the occurrence of extreme weather events and natural disasters. Getting citizens on board when it comes to being prepared for the changing risk landscape in the EU is essential in building societal resilience. The importance of the population’s preparedness to deal with disasters has also been underlined by the Commission’s identification of the Union Disaster Resilience Goals (2023/C 56/01). One of these goals focuses on increasing risk awareness and the adoption of risk prevention and preparedness measures among the population. Research has shown that simply advising people of potential risks in their region is not necessarily sufficient to motivate them to prepare. Yet, preparation is key to an adequate responses in emergency situations and improving preparedness may thus be a powerful tool to support the population’s ability to respond in times of crisis. The EC JRC’s Competence Centre on Behavioural Insights will present a study conducted in five member states (N = ∼1000 per country), which investigates the effect of envisioning a disaster situation, and therefore explicitly eliciting personal affectedness, on individuals’ self-reported preparedness intentions and preparedness behaviours. The study uses multiple measures for intentions and preparedness behaviours, including click-through to external information and an incentivised preparedness game.
Ambivalence is a presumably unpleasant experience, and coming to terms with it is an intricate part of human existence. It is argued that ambivalent attitude holders cope with their ambivalence through compensatory perceptions of order. We first show that ambivalence leads to an increase in (visual) perceptions of order (Study 1). In Study 2 we conceptually replicate this finding by showing that ambivalence also increases belief in conspiracy theories, a cognitive form of order perception. Furthermore, this effect is mediated by the negative emotions that are elicited by ambivalence. In Study 3 we show that increased need for order is driving these effects: Affirmations of order cancel out the effect of ambivalence on perceptions of order. Theoretical as well as societal implications are discussed.
In a time of rapid climate change, understanding what may encourage sustainable consumer behaviour is a vital but difficult challenge. Using an attitude network approach, we investigated which associations people have towards conventional and bio-based plastic in order to develop an empirically-based approach to initiate attitude- and behaviour change. With a qualitative study (N = 97), we distilled 25 evaluative reactions (i.e. beliefs, emotions, and behaviours) that encompass people's attitudes towards using (bio-based) plastic. These reactions were used to create a new scale, which was subsequently tested among 508 online participants. The resulting data was then used to build a network displaying relationships between participants' evaluative reactions regarding plastic use. Analyses of this network indicated that guilt was most strongly connected to people's willingness to pay more for bio-based plastic products. Based on this, we conducted another study (N = 285) in which we experimentally manipulated guilt (general guilt, personal guilt, and control condition) to determine its effects on people's willingness to pay for a sustainable cause. Results indicate that manipulating guilt can lead participants to donate more to a sustainable cause. This effect was fully mediated by self-reported guilt. Determining which factors influence consumers to change their buying behaviour towards sustainability is the first step in creating a demand for more sustainable products amongst the public and investors.
We study public beliefs about the gender composition of forcibly displaced populations. In an online survey experiment representative of the adult population of six EU countries, respondents consistently underestimated the share of women among the people displaced by the Russian war on Ukraine who had arrived in their country. We show that a randomly applied belief-correction intervention effectively prompted updates in public beliefs, aligning them more closely with actual numbers. We also find evidence that the source of information matters: updates are greater when the intervention cites official statistics rather than other people's opinions. Despite clear evidence of widespread preference against male migrants, however, the intervention did not alter attitudes or policy support. We identified no statistically significant impact on respondents' perception of the displaced Ukrainians' influence on the crime situation in the host country, respondents' support for refugee family reunification policies or respondents' perception of migrants' impact on the economy. While all these measures correlate with beliefs about gender composition, the intervention did not significantly affect any of them.
Enabling, supporting and promoting positive health-related behaviours is critical in addressing the major public health challenges of our time, and the multifaceted nature of behaviours requires an evidence-based approach. This statement seeks to suggest how a much-needed enhanced use of behavioural and cultural science and insights for health could be advanced. and methods: Public health authorities of Europe and Central Asia and international partner organizations in September 2023 met in Copenhagen, Denmark, to discuss the way forward. Drawing on 1) country reporting to WHO, 2) interview study with public health authorities and 3) the meeting deliberations, this meeting statement was developed. The meeting statement presents a joint call for step-change accelerated use of evidence-based approaches for health behaviours. Actionable next steps for public health authorities and international and regional development partners in health are presented. The way forward involves increased resource allocation, integration of behavioural insights into health strategies, advocacy through case and cost-effectiveness examples and capacity building.
