We have once again updated our encyclopedia of polarisation and I will take it as an opportunity to introduce some of the features again.

On ❄️ polarization.wiki you can find descriptions, formulas, data and applications of the most common measurements of political polarization.

¹ Ich benutze nicht den Begriff "Befreiung", den von Weizsäcker 1985 geprägt hat, weil die meisten Deutschen es damals nicht als Befreiung empfunden haben und zu viele es heute noch nicht tun. Von Weizsäcker meinte es gut, aber das ist ja bekanntlich nicht immer gut gemacht.

Man kann nicht des Endes des Zweiten Weltkrieges gedenken, der mit dem deutschen Angriff auf Polen begann, und dazu Vertreter eines Landes einladen, das ein Nachbarland angegriffen hat.

Insofern sind die Nachfahren:innen der Sowjetunion unter den aktuellen Umständen bei Gedenkveranstaltungen in Deutschland adäquat vertreten.

Es erscheint heute notwendig, daran zu erinnern, dass Deutschland nicht von den Alliierten und Russland besiegt¹ wurde, sondern von den Alliierten und der UdSSR. Etwa die Hälfte der Roten Armee kam aus den anderen Sowjetrepubliken, das größte Kontingent davon aus der Ukraine. #8mai

In line with our theory, we find that incumbents and high-profile party members are punished more by voters. They lose more votes compared to lower-ranking party members. 6/

We theorize that this collective accountability occurs because MPs are regarded as typical representatives of their party facilitating generalizations to the entire party brand. 5/

This is an important result as prior research on scandals and corruption focused mostly on repercussions on the implicated politicians. The fact that entire parties are punished electorally establishes an important second channel of accountability incentivizing parties to vet candidates carefully.4/

We estimate the effect of the scandal, a loss of 4 percentage points to the party, through a difference-in-differences design—by differentiating trends in pre-scandal postal and post-scandal urn voting. 3/

The German “mask affair” refers to a 2021 scandal in which individual MPs belonging to the CDU/CSU, profited personally from government deals to procure medical masks mid-pandemic. The scandal surfaced shortly before state elections in Baden-Württemberg (BW) and Rhineland-Palatinate (RP). 2/

New 📰: In "Can Individual MPs Damage Their Party’s Brand? Quasi-Experimental Evidence from a Public
Procurement Corruption Scandal" out in @thejop.bsky.social @lukrudolph.bsky.social and I show that the "mask affair" cost the CDU 4%-points in elections. www.journals.uchicago.edu/doi/10.1086/... 1/

Of course, some constituency results ended up different than expected but a citizen forecast also gives you pretty accurate expectations of which races will be close:

We had hoped to get this out before the 2025 election but, well, the government broke before that. Here are a few insights from the article: 1. Forecast worked relatively well overall and, as expected, groups forecasts much accurately than individual respondents.

🗣️ On April 1st, I started as a PhD Candidate and Research Associate in @aleininger.bsky.social's team at TU Chemnitz, where I'm looking forward to working on elections, public opinion and affective polarisation at the local level.

Stay tuned! ☺️ 📊
