Thanks @eivindy.bsky.social! My first foray into the mysterious world of #SelectionBias. Very happy to receive feedback, and to discuss opportunities for improving/expanding this work!
🧵 THREAD: Preprint from @chrisrayner.bsky.social reveals how to fix selection bias in the Norwegian #MoBa study using population-wide registry data! For the first time, we can quantify and adjust for selection bias in this major epidemiological resource.
Spread the good news!

Every time I teach #CausalInference, a few people have their world blown up.
They'll learn about #Table2Fallacy, or #SelectionBias, or the problems with change scores and it'll 'break' their research.
It's a tough moment. But at least I can say 'I've been there'. As we all have, and all will be.

A tip-off is how *linear* the growth in test scores was.
The same linearity led us to suspect similar bias in a critique of our paper.

Besides a possible hard selectionbias in the pool of respondent ... meh
Well if just 10-20% of serious researchers/scientists are actually considering moving it's still a huge blow.
But yes they should consult a pollster the next time. LOL.
