📖 New publication: "When Gender Trumps Skills: Employment Trajectories of Austrian Parents After Their First Birth". Claudia Reiter and @sonja-spitzer.bsky.social show that in AT, gender differences in parental leave are huge: Mothers take 416 days, fathers only 9.

We all seem to agree that many survey experiment interventions (eg reducing polarization) are limited because their effects are short-lived. But when would an effect be sufficiently durable? 1 year, 10 years, forever?

We expect medication to quickly end a fever but not to prevent fevers forever.

Danke, Dreck. Schade, dass du nicht regierst.

Obviously, this is not to say that polarization is necessarily problematic. My point is rather that interventions on this (and many other social science phenomena) would benefit from clarifying what “success” looks like. A good intervention is scalable in scope, but can it be lasting in time?

What are reasonable expectations?
The key may be problem alleviation vs problem prevention. But then we seem to focus far too little on prevention. If the goal is long-term absence of polarization, alleviation may simply be inadequate (similar to how few drugs help long-term absence of disease).

New working paper!

I examine whether exposure to local unemployment during adolescence shapes immigration attitudes in adulthood, focusing on the long-term imprint of early economic insecurity

Acquiescence Bias and Criterion Validity: Problems and Potential Solutions for Agree-Disagree Scales - Political Behavior Political Behavior - Scholars frequently measure dispositions like populism, conspiracism, racism, and sexism by asking survey respondents whether they agree or disagree with statements...

New w/@scottclifford.bsky.social.

Lots of work uses agree-disagree scales, and a lit review shows these are 1) frequently just measured in one direction (agree = higher trait) and 2) correlated with each other.

This has potentially big issues for conclusions.

Everything for the fans: Party responsiveness across the EU over time | European Journal of Political Research | Cambridge Core Everything for the fans: Party responsiveness across the EU over time

Are parties responsive to public opinion? In my first research note, just published in @ejprjournal.bsky.social, I find consistent evidence that parties across the EU shift their positions to align with the preferences of their partisan supporters: doi.org/10.1017/S147...

I was a fellow at Harvard Business School last year and attended a talk with an AI booster who said something like "don't trust AI (it's inaccurate) but use it every day."

When I pointed out this contradiction, and that we don't typically encourage the adoption of broken tools, he was unmoved.

Some people like using our (w/ @markuswagner.bsky.social) heroes & villains paper to teach partisanship.

We've made it easier (and fun?) for students with a new online playground 🦹

Do ordinary Republicans and Democrats really avoid each other in everyday life? In a new working paper with Delia Baldassarri, we present descriptive and experimental evidence to challenge the view that partisanship drives the formation of social relationships.

Dieses „Streitgespräch“ ist primär schlimm. Kullmann rattert die Positionen runter, die man von veralteten Chemiekonzernen erwartet.

Von @gruene.de erwarte ich aber mehr: Reflektion + Argumente statt Floskeln wie „Unsinn“ und „Einspruch“ + EVP-Blaming. Gerade verkörpert die Partei Spahn-Niveau.

Europe is committing even more to wind energy and other renewables.

Yesterday’s Hamburg Declaration by 🇧🇪 🇩🇰 🇫🇷 🇩🇪 🇮🇪 🇱🇺🇳🇱 🇳🇴 and 🇬🇧 reaffirmed this.

The stronger the external threat, the stronger the pushback to wind energy by Trump, the stronger the commitment to wind in 🇪🇺
