In an ongoing project, we ask which countries citizens prefer as benchmarks for policy decisions.
Pilot data from the UK show that Denmark is ranked as one of the most preferred reference countries, particularly in relation to migration policy.

Which countries do citizens see as credible models for reform?
I’m presenting pilot data @lundsuniversitet.bsky.social today:
Nordic and richer countries are preferred benchmarks, but performance information can shift who is seen credible.

Our article “Unsuccessful Candidates Are More Concerned About Electoral Fairness than Election Winners” is now online @thejop.bsky.social
Using RDD and elite survey data from Denmark, we show that losing candidates express greater concern about electoral fairness.

3️⃣ What about citizens?
In a parallel survey (N = 1,428), FPÖ supporters also preferred the “fewer migrants” evidence.
Left-leaning voters leaned toward the “poverty” evidence, but less strongly.

2️⃣ Main result: politicians
We tracked which link they clicked.
Candidates from ideologically extreme parties were most likely to select evidence aligned with their party’s position.
This pattern was especially clear among far-right candidates (FPÖ).

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.

New preprint 📄
Voters navigating complex, multilevel systems are exposed to many kinds of political information. But what kind do they actually seek — and use?
We find voters prefer policy over principles and they update their vote intention accordingly.

Yesterday, I had the pleasure of chairing the PhD committee for Mathias Rask Jeppesen. Using audio data, his dissertation makes an original contribution to the study of political communication.
Check out his great work (politica.dk/politicas-ph...), including a forthcoming article in PSRM.

The data confirms it: According to CHES 2023 on Ukraine, the far right is the party family that strongly seeks ties to the Kremlin and favors trade and diplomacy with Russia, relative to others.

Well, instead of a far-right government, Austria offers a study in coalition dynamics.
The three parties differ in left-right and GAL-TAN positions, as shown in the latest @chesdata.bsky.social release. It will be interesting to see how they govern together and how voters respond.

The difference between ÖVP and SPÖ supporters likely reflects how they see their own party and the others:
ÖVP supporters feel more distance to SPÖ than vice versa and may want NEOS for balance, while SPÖ supporters might not see the same benefit of having NEOS in the mix.
