How deep a divide do we tolerate? Measuring the willingness to engage with differently minded others (Wedo)
Fostering contact across political camps is crucial to combat affective polarization and to sustain healthy democratic discourse. Researchers therefore have become increasingly interested in better understanding the factors that promote or hamper political exchange. The present research contributes to this goal by introducing WEDO, a new measure to assess the willingness to engage with differently minded others based on behavioral preferences in …
A million reasons or just one? How coin flips impact the number of relevant reasons for decisions
When individuals face difficult decisions, they may turn to random decision‐making aids, such as coin flips, for support. Here, we show that flipping a coin before making a decision impacts the number of reasons that individuals consider when making consumer choices (Study 1), policy decisions (Study 2), personal decisions (Study 3) and breakup decisions (Studies 4a, 4b, 4c). In Studies 1 to 3, flipping a coin resulted in fewer reasons or a reduc…
This feels like the right choice: How decision aids may facilitate affect-based valuation
When individuals cannot make up their mind, they sometimes use a random decision-making aid such as a coin to make a decision. This aid may also elicit affective reactions: A person flipping a coin may (dis)like the outcome, and thus decide according to this feeling. We refer to this process as catalysing decisions and to the aid as catalyst. We investigate whether using a catalyst may not only elicit affect but also result in more affect-based d…
Deciding advantageously after flipping a coin
Folk wisdom, advice columns, and pop culture suggest that when undecided, individuals may flip a coin - not to simply follow the suggestion, but to inspect their reaction to the outcome and then use the reaction to decide. While being intuitively appealing, it remains an open question whether this strategy results in advantageous decisions. Here we used an adapted version of the Iowa Gambling Task to test whether flipping a coin before making a d…
Construal level mindsets modulate gender categorizations in preschool children
Social categorization is a crucial information processing strategy that adults deliberately adjust depending on goals and situational requirements. This study investigated whether flexibility in categorization is similarly present among preschool children. More specifically, we tested whether spontaneous gender categorizations are more pronounced for children with a situationally induced abstract compared to concrete construal level mindset. Sixt…
Differences in faces do make a difference: Diversity perceptions and preferences in faces
Throughout previous research focusing on individuals' diversity perception, it remains somewhat unclear which attributes (i.e., objective diversity) are reflected in perceptions of diversity. This manuscript investigates whether individuals consider objective differences in ambiguous facial information (which are not related to gender or race) when making diversity judgments and decisions. Throughout seven studies, facial information of group mem…
The Psychology of Fake News: Accepting, Sharing, and Correcting Misinformation
This chapter investigates two aspects of misinformation: how to determine whether information (such as a news story) is true, and how the truthfulness of information affects its diffusion or spread. The chapter has a particular focus on the significance of social media for misinformation (in particular fake news): its prevalence, impact, and methods for identifying and studying the phenome- non. We review recent literature on how computational me…
You should go for diversity, but I'd rather stay with similar others: Social distance modulates the preference for diversity
Toss and turn or toss and stop? A coin flip reduces the need for information in decision-making
Less Than I Expected and oh so True? On the Interplay Between Expectations and Framing Effects in Judgments of Truth
This article investigates the negativity bias in truth judgments, which holds that negatively (vs. positively) framed statements are more likely to be judged true. Throughout four studies we find that expectations moderate the negativity bias. In particular, Study 1 failed to replicate the negativity bias with standard items. In Study 2 we investigated individuals' expectations regarding the statements. When systematically adjusting the percentag…
