I live in Hamburg-Eimsbüttel, the most densely populated district. Parking a car there costs 67 euros/year.
A children’s room of the same size costs 440 euros a month.

But of course it would be unfair to make that comparison, because housing is a private matter and has always been expensive.
Right?

Great graphic showing cities on a triangle graph showing if they are most oriented to public transit, active mobility or cars.

Great graphic showing cities on a triangle graph showing if they are most oriented to public transit, active mobility or cars.

Have you seen this? This recent study of mode share (the % share of transportation trips that are by car, transit, walking, biking etc) relative to city size and income levels in almost 800 cities in 61 countries. Interesting results. HT @davidzipper.bsky.social

Despite all the chatter, social media bans for teens lack evidence! New paper out in Nature Health.

(1) Harms from social media are real & serious.

(2) We need regulatory action but bans are not nuanced, do not empower youth, & are not supported by evidence.

"Alle großen Studien zeigen: Armut ist der größte Risikofaktor. Wer in armen Verhältnissen aufwächst, dessen Risiko ist zwei- bis dreimal höher, psychisch belastet zu sein. [...] Dürfte ich mir nur eine Präventionsmaßnahme wünschen, dann wäre es die Kindergrundsicherung." 🔥

Ein sehr schöner Text. Ich kann mich nicht entscheiden, ob ich den perfekten „Dzoker“ oder „Ab jetzt Gelsenkirchen: Shopping in der Hochstraße in Buer und Joggen im Nordsternpark. Džeko wird diese Umstellung nicht schwerfallen. Er war schon in Wolfsburg.“ lustiger finde.

Während ICE in den USA tötet, fordert die AfD Sachsen-Anhalt in ihrem Regierungsprogramm zur Landtagswahl ähnliche Strukturen & nutzt Formulierungen wie „sexuelle Abweichungen und nicht-reproduktive Lebensweisen“. Das Programm ist voll von Demokratiefeindlichkeit. Wer AfD wählt, wählt Faschismus!

Abstract
According to intergroup contact theory, meaningful interactions between members of different social identity groups can lead to decreases in prejudice. However, the literature on intergroup contact has generally emphasized contact-based interventions that involve positive contact experiences in highly controlled environments like research laboratories or classrooms, or infrequent intimate intergroup contact experiences, like intergroup friendships. In this Perspective, we review the literature on how intergroup contact manifests in everyday settings, which challenges established views that contact is readily available, positive and leads to consistently positive within-person changes. We describe how variations in contact valence and environmental affordances for self-selection influence individual- and macro-level segregation dynamics, which create conditions for stable trajectories of contact and intergroup bias, or contact habits. We then propose a habit–rupture model of contact, according to which changes in intergroup relations through lifespan and macro-level disruptions act as ruptures, leading to the development of new contact habits. Considering contact and its effects through a habit and rupture lens identifies realistic and ecologically valid opportunities to apply intergroup contact in the service of the social good.

Oxford University ‘withheld information about harassment claims’ Miles Hewstone, who quit in 2019 but retained his emeritus titles for years, is accused of making unwanted advances towards students and researchers

“We requested information about the case to at least protect attendees of our future events and potentially act against Hewstone, however, Oxford University never provided any information.”

#DefundDFG“? Die Empörung über die Entscheidung der DFG, KI in der Begutachtung zu erlauben, ist groß.

Ich glaube aber: Die Debatte greift zu kurz. Und die Entscheidung der DFG nur folgerichtig.

A new paper by George Borjas—who served this past year in the Trump White House designing some of its anti-immigration policies—claims to display evidence of ideological bias among researchers who study immigration.

Did not think I'd witness a Nature journal publish a piece calling the US a fascist country in the title / abstract.

Thanks to Lauren and the rest of the team for picking up this crucial fight — in this paper and elsewhere. Please read and share widely.

Important topic! I’ve always wondered what happens to all the young players who build their whole identity around being footballers, then get released from academies. In Germany, only about 1–5 percent of youth players in “Nachwuchsleistungszentren” make it to professional football.

I can’t imagine what it was like to be a victim of Hewstone, but I recognise how important this article is for the women he harassed. At the same time, I’m shaken that our community stayed silent for so long. I have deep respect for the women who exposed his wrongdoing.

Oxford University Has Failed Women Over Harassment Concerns, Staff Say The university has repeatedly been slow to act against male academics accused of sexual misconduct and inappropriate behavior, a Bloomberg investigation found.

This—on my former university, department, and advisor—is harrowing but required reading for all social psychologists. www.bloomberg.com/news/feature...

I totally agree. Nobody really wants Habilitationen; everyone thinks they’re outdated, yet they persist. Already seven years ago, @dgps.bsky.social called to end the whole system. See
