Several more papers have been accepted and will be coming out soon - I am looking forward to sharing them here once they appear online!

A growing part of the population actively avoids the news. Does this affect how congruently they vote? In @epsrjournal.bsky.social, we find a negative association between news avoidance and congruent voting - especially strong among low-knowledgeable respondents.

Survey methodology! When given both options, who prefers to take a survey on paper, and who answers online? @marchooghe.bsky.social, Chloé De Grauwe, @ambervoets.bsky.social and I find that push-to-web strategies might bias samples, especially in terms of age.

There is a winner-loser gap in political support, but what affects perceived winner or loser status? In @bjpir.bsky.social, we find that differences between election results and public opinion polls explain changes in political trust.

We often use hypothetical questions to probe intended behaviour, but how trustworthy are they? @marchooghe.bsky.social and I tested the validity of hypothetical turnout questions @actapolitica.bsky.social and found that they predict subsequent reported turnout well!

Spatial and valence models are the theoretical workhorses in electoral research, but what matters most to voters: ideological proximity or party competence? @annkristinkolln.bsky.social and I found out in @polstudies.bsky.social

Turns out: it's valence!

Over the past months, some new articles have come out that I haven't shared here yet. So here it goes, an overview of recently published work 👇

Does ideological congruence or perceived competence matter more for vote choice? @dieterstiers.bsky.social & @annkristinkolln.bsky.social argue both matter, but valence consistently outweighs spatial considerations. Read more: buff.ly/J3cy21u

Abstract
Rational choice theories offer one of the major explanations for citizens’ voting behavior. The most prominent models within the rational choice framework – spatial and valence voting – share the same roots but differ in central aspects, emphasizing ideological congruence and competence evaluations, respectively. In this note, we provide a direct test of the models’ relative strength. Does a party’s issue congruence with a voter (spatial) or its effectiveness in handling important issues (valence) have a larger effect on vote choice? Our results from lab-like conditions using a novel conjoint experiment show strong evidence for both models, but valence evaluations consistently trump spatial considerations. These results have important implications for research on electoral behavior, party politics, and democratic representation.
