I just got tear gassed along with thousands of union members, many of whom had their families with them. Federal agents at the ICE facility tear gassed children. We must abolish ICE, DHS, and we must have prosecutions. I expect to see enforcement of our city code prohibiting the use of tear gas.

We envision an increased (!) involvement of humans in the evaluation of social science.

Excited to have just finished this pre-analysis plan with @larahankeln.bsky.social, @johannesbrehm.bsky.social, and Henri. It will be interesting to see which, if any, of our predictions will be borne out by the data. More on that in the new year. In the meanwhile, let me tell you about our theory.

Hvorfor er stigende ulighed et problem? Høj ulighed hænger sammen med lav socialmobilitet.
Socialmobilitet er vigtigt:
Forskning viser: Hvis læger med en lav socioøkonomisk baggrund behandler patienter med lav socioøkonomisk baggrund, lever patienterne længere og bedre.

Physician–patient SES match improves low-SES health, reducing socio-economic health inequality. Just Accepted new paper by Ida Lykke Kristiansen @idalykkekr.bsky.social and Sophie Yanying Sheng zurl.co/R7Sx8
The Physician-Patient Match and Health Inequality
Abstract. This study explores the impact of primary care physicians’ childhood socioeconomic status (SES) on their patients’ health and socio-economic inequality in health. We measure physicians’ SES by their parents’ education and find that SES concordance decreases low-SES patients’ mortality substantially, while high- SES patients’ mortality does not depend on their physicians’ family background, resulting in a reduction in the SES-mortality gradient of 25%. SES concordance improves low-SES patients’ health by increasing care at the intensive margin, increasing detection of chronic conditions, and improving adherence to treatment. SES concordance elevates communication, fosters empathy and trust between physicians and low-SES patients.

Makes you consider what political capital actually is.
you don't have to put on blackface to get social media attention. you can simply develop mild depression, join a menswear forum, spend the next 15 years arguing about pants, and then weaponize the knowledge against your enemies on social media.
