Unser neuer Call for Papers für euch. In der nächsten Ausgabe soll es um Computational Social Science (CSS) gehen. Schickt uns dafür eure Texte bis zum 31.03.2026 an [email protected]. Auch Beiträge jenseits des Heftthemas sind immer gerne gesehen.
We're thrilled to open registration for our 1st 2026 Replication Games. The event will be at the University of Zurich on January 19th.

Psych, public health, pol sci and econ studies will be reproduced! Register here: www.surveymonkey.ca/r/Replicatio...

Throwing (more) money at problems makes them go away 😉

Since social psychology was not at the center of the replication crisis and does not have massive power abuse problems it definitely needs more funding!!!
Big new blogpost!

My guide to data visualization, which includes a very long table of contents, tons of charts, and more.

--> Why data visualization matters and how to make charts more effective, clear, transparent, and sometimes, beautiful.

Today, we fined X for non-compliance with transparency obligations under the DSA.

We're holding X accountable for:
🔹Deceptive design of its ‘blue checkmark’
🔹Lack of transparency of its advertising repository
🔹Failure to provide access to public data for researchers

AI chatbots can shift voter attitudes on candidates & policies, often by 10+pp
🔹Exps in US Canada Poland & UK
🔹More “facts”→more persuasion (not psych tricks)
🔹Increasing persuasiveness reduces "fact" accuracy
🔹Right-leaning bots=more inaccurate

It seems that I have spent quite a bit of time with you this year @nulliusinverba.bsky.social 😊

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.
Needed - larger samples, more realism about (the lack of) heterogeneous treatment effects:
-"less than a third of proposed hypotheses were supported... the largest predictor of positive exp. results was sample size"
-"moderation hypotheses were rarely significant"

I had a lot of fun making this choropleth map of property sales prices in Germany.

Predictably, big cities have the highest property prices. This pattern is typical now.

German academia: great place to work? You should think twice before giving it a try: Permanent positions are very rare, most scholars have to drop out after some precarious years. @dianakwon.bsky.social has written a great piece about this for @nature.com and also talked to yours truly. #IchBinHanna

How are social bias and CSS interconnected? 🤔

@aytalina.bsky.social, @janabernhard.bsky.social, @valeriehase.bsky.social, and I argue that social bias shapes CSS as a field and as a methodology. Progress in CSS depends on engaging with both dimensions! osf.io/preprints/so...
