First week 'critical' to avoid children missing school later, parents told
Data suggests more than half of children who miss a day at the start of term become persistently absent.

A fantastic teaching example of a predictor being misinterpreted as having a causal effect.

In light of record submission rates and a large volume of AI-generated slop, SocArXiv recently implemented a policy requiring ORCIDs linked in the OSF profile of submitting authors, and narrowing our focus to social science subjects. Today we are taking two more steps:

There's no methods development that the observational medical literature can't misuse. Its TTE now, but you look back at when propensity scores were fashionable and see the same thing.

This year explaining regression to the mean took forever but I’m sure next year will be better.

Here’s an example of one we did where working through the process made it clear that the data simply weren’t sufficient to answer the question of interest:

How do I get people to understand that high quality data collected with intention and analyzed by experts have even more potential to revolutionize health care?
Can't even make jokes anymore because Deloitte did use AI to say that AI is good...

A special day for Cohort Membear from @clscohorts.bsky.social who travelled to Luxembourg to meet its mascot counterpart from @uni.lu ACADI 🧸🦎
Loved talking about causal inference with compositional data to a lovely audience from @liser.lu and LIH.

How do we incentivise people to publish fewer papers?
We need to live in a world where saying 'I have published over 500 papers' is widely understood as a red flag, not as something to brag about.

Have you ever wondered how the transportability of an estimate may be affected by the choice of effect measure?
Join us in Nov to hear from @mpiccininni3.bsky.social on why the causal risk ratio might be more stable and transportable across settings.

I guess Rubin choosing "Missing at Random" for the scenario in which it is evident that the data are not missing at random is a close contender.

The constant over- generalization of their data to everyone’s population (not just the UK) is aggravating. Plus, the work is just a bunch of correlation studies that they treat as causal with, as you note, a huge selection bias. Why isn’t this discussed more in the UK?

It is not everyday that 2 out of the 5 'most read' papers in @intjepidemiol.bsky.social are yours!
Rather pleased, especially given both of these took *4-5 years* each from start to publication!
