Do campaigns make voters less vulnerable to framing?

Our study of Denmark’s 2022 EU referendum suggests they can. Framing effects declined as voters became more informed and drew on their own EU attitudes.

Happy to share it's now accepted in the EJPR!

Policy Preparation Inside the European Commission is out with OUP @oxfordacademic.bsky.social

It’s about the behind-the-scenes stage of EU policymaking that shapes everything—yet rarely gets the spotlight: how the Commission prepares its proposals.

Politically

The findings highlight the importance of addressing negative stereotypes and enhancing information flow to reduce bias in diversifying Europe. 9/9

The study, thus, suggests that negative expectations toward minorities stem less from sticky ethnic attributes and more from the social and cultural factors associated with them. 8/9

Theoretically

Ethnic bias in expectations operates through multiple complementary channels related to
➡️ minorities’ ressources and ‘abilities to pay’
➡️ the degree to which cultural values are (assumed to be) shared, and
➡️ compliance with socially agreed-upon norms. 7/9

Findings #2

However, this ethnic bias diminishes when information on individuals’ socio-economic status, cultural values, or norm compliance is available. When all three factors are accounted for, the expectation gap disappears. 6/9

Findings #1

The ethnic majority in Denmark initially expects individuals with Middle Eastern names to contribute 9.2% less to public goods than individuals with Danish names. 5/9

In an innovative conjoint experimental design in DK, the study manipulated participants’ information about hypothetical individuals who engaged in a public goods game.

The design provides a good measure of expectations and, importantly, enables to causally test the different mechanisms. 4/9

I argue that ethnicity operates as a bundled signal for people's socioeconomic resources, cultural alignment, and norm compliance.

The main argument: It is these factors, not ethnicity per se, that explain negative expectations toward minorities' cooperation and contribution. 3/9

Negative expectations toward minorities often fuel social division and undermine public goods provision. But what drives these biases? 2/9

🚨New article🚨

Why does the ethnic majority expect that ethnic minorities "free ride" and contribute less to the collective?

In a new article in @bjpols.bsky.social, I show that negative expectations are driven by the correlates of ethnicity rather than ethnicity itself 🧵👇

Wilma 🐶 has done well adjusting to life in Denmark. She quickly understood the importance of enjoying the sun, esp during dark winters. 😎
But what about migrant children, how does their integration work? In a @pnas.org study, Wilma's colleague @matkruse.bsky.social shows:

Thank you so much for you and Wilmas awesome review! 🙏🙏

Conclusion

The study points to the complex nature of intergroup integration but at the same time suggests that local settings with some minority members may foster minorities’ wellbeing without substantively reducing the well-being of the ethnic majority. 8/9

For minority students, having similar peers increases well-being by promoting feelings of acceptance and belonging and reducing loneliness.

For majority students, a substantial share of out-group peers reduces well-being in particular by generating a dissatisfaction with the local environment. 7/9

These effects are driven by different theoretical mechanisms:

6/9

For majority: Effects are largest when the share of minority students is substantial

For minority: Marginal effects flatten out + are substantial at lower conc. of similar peers

➡️ Whereas being in a dominant position is key for the majority, simply having someone is sufficient for the minority 5/9

What do we find?

Exposure to ethnic similarity increases well-being (std.) across diff. identification strategies and measures of similarity.

Ex: A higher share of non-Western students in the classroom decreases well-being for majority students and increases well-being for minority students. 4/9

We combine Danish registry data with panel survey data from all 4th to 9th grade students in Danish public schools (N∼700,000). To reduce selection, we use three different sources of variation in the classroom ethnic composition: within-school, within-family, and within-student variation 3/9

We argue that exposure to ethnic similarity in the local setting promotes well-being for both the ethnic majority and the ethnic minority but for theoretically different reasons. 2/9
