Two simulation studies in this paper show that doubly robust methods for causal inference—especially regression weighted by inverse propensity scores—are more robust to model misspecification than traditional regression across many scenarios. link.springer.com/article/10.3...

Na, das bringt das Land bestimmt nach vorne! Die drittgrößte Wirtschaft der Welt sagt ihren Beschäftigten: Fuck you! Wir sollten auch noch die Kündigungsfristen für Wohnungen auf drei Tage herabsetzen und die gesetzlichen Krankenversicherungen ganz abschaffen, wie in den USA. Dann wird alles gut!

This is really big (if it works!)—a big limitation for the use of R in simulation up to this point has been memory bloat. I’ve had to turn off parallel processing/reduce the number of workers many times in my {targets} workflows due to OOM errors. Hopefully this will solve that problem #RStats

“we are trapping 21st-century minds inside 19th-century academic hierarchies.” This essay gets a lot right about problems with German science. I would add that the hierarchies and precarious contracts lead also to systemic abuse and scientific misconduct. open.substack.com/pub/realimag...

First post of the year, new paper out today: we present possibly the biggest case of systematic Measurement Schmeasurement in tech use. It seems that most studies on gaming (videogame) addiction/disorder haven't measured gaming after all. This research took years, so long 🧵 doi.org/10.1098/rsos...

I had not heard of a "mode effect" until @georgiatomova.bsky.social invited me to be part of this paper. If you've not heard of them either, I'm thrilled to share our introductory paper (with DAGs!) in @amjepi.bsky.social Turns out they're really important for anyone using survey data!

New chart from Mike Males using MTF and Pew Research data finds that trends in teen social media and smartphone use are unrelated to teen loneliness (which hasn't changed much over the years anyway aside from an unexplained dip in the 2000s).

new paper by Sean Westwood: With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

"only about 5% of the variance in personality can be predicted from digital footprints, and personality‐tailored messages show negligible effects on behavior... When design and evaluation flaws are controlled, the combined end‐to‐end effectiveness of psychological targeting approaches zero."

Including students with special educational needs (SEN) in educational large-scale assessements is an ongoing challenge. Several feasibility studies in the NEPS were conducted that have examined the psychometric quality and comparability of cognitve assessments administered to students with SEN. 👇
