New paper out with @boryslaw.bsky.social 🥳 In which we sketch out how to rethink measurement invariance causally for applied researchers. And provide a causal definition of measurement invariance!

www.sciencedirect.com/science/arti...

Rethinking measurement invariance causally

Highlights:
It is preferable to work with a causal definition of measurement invariance
A violation of measurement invariance is a potentially substantively interesting observation
Standard tests for measurement invariance rely on strong assumptions
Group differences can be thought of as descriptive results

Conceptual graph illustration the central points of the manuscript. A group variable is potentiall connected to a construct of interest which affects items. Measurement invariance is violated if the group variable directly affects the items, for example by modifying the loadings from the construct to the items, or by directly affecting an item

To make this less abstract, consider a scenario where students take an exam, R, meant to capture some ability, T, and then are admitted to a program, V, depending on their exam results: R → V. This is sufficient to result in a violation of the statistical definition of measurement invariance. Exam results and admission are not independent given ability because exam results have a direct effect on admission. Even if we know somebody’s ability (e.g., we know it’s very high), learning about their admission status (e.g., they were not admitted) can tell us something about their exam result (e.g., it may have been worse than expected). According to the causal definition, this in itself does not constitute measurement bias, which seems a sensible conclusion here. After all, the scenario does not involve any reason to believe that the measurement process varied systematically by admission status. Admission happens after the exams took place, it cannot retroactively influence the measurement process (and, for example, lead to unfair treatment depending on admission status).

New post by me:

The decline in cancer mortality is about much more than smoking. We shouldn't minimize the very real impact of many contributors — including improvements in diagnosis, medical and surgical innovation, vaccination against cancers, and more — to the reduction in cancer death rates.

The decline in cancer mortality is about much more than smoking

I respond to the claim that the decline in cancer mortality is mostly, or almost entirely, because of the decline in smoking.

43% of participants didn't use the app *at all*. Only 22% even completed 4 of the 7 modules.

This is also not new. Lots of other trials also show us, using quant and qual data, that adolescents don't much like universal interventions, and don't do the tasks/homework (I can share refs if helpful)

The newest dinosaur discovery from Scotland! Over 100 tracks made by theropods & sauropods.

In the same spot where, 170 million years later, Bonnie Prince Charlie landed on Skye to escape the English.

When the Prince was on the run, he sprinted in the footsteps of dinosaurs!
