2️⃣4️⃣🎁🎄 Doing something new for Advent this year: one great data journalism piece per day until Dec 24. I’m teaching a data journalism course @hertieschool.bsky.social next semester, so this is partly selfish homework. But maybe interesting for others too.

Had a great time at the @zweitstimme.bsky.social Workshop on Elections, Public Opinion & Elite Behavior. I presented my work on why minority groups vote, and how these motivations relate to turnout among LGB and ethnic minorities. Amazing conversations and a very inspiring group!

🗳️ The DFG-funded project @zweitstimme.bsky.social drew widespread attention from media and scholars in the context of the 2025 German federal election. Besides national-level party vote shares, they forecasted district-level vote shares for candidates, and whether districts become “vacant”. (1/5)
Quote: “In the 2025 federal election in Germany new rules meant that for the first time some candidates have won their constituency, but no seat in parliament. Our prediction model allowed to forecast such vacant constituencies.” from Hannah Rajski
