Per protocol analysis strikes again! Folks, if you randomize but then don‘t analyze some of the people who got randomized (maybe because they didn’t adhere to instructions, maybe because they dropped out), randomization will no longer do all the heavy causal inference lifting.

A variation: Scientists who claim they’re “not interested in causality” because they assume the term only applies to deterministic, law-like relationships that are unrealistic in their field. Instead, they’re interested in how “X drives Y”, the effects of X, the “extent to which X matters for Y”>

This is an interesting development...

Super excited to see that somebody finally wrote about this 🥳 If you do research about research, you really need causal thinking (just like when you do research about anything else really).

looking at academic bsky, one might get the opposite idea, but out in the wild, many researchers have never heard of or worried about formal causal inference, and they get bewildered to hear that perhaps they shouldn't just freely use causal language when interpreting their correlational results.

As a sidenote: the article was also a great (and in many instances tedious) exercise in writing a fully reproducible manuscript. I think it was worth it, but definitely led to some headache and frustration (especially since we wanted the result to look pretty).

Hoping that our article will make a change and prompt colleauges in science studies to think more thoroughly about their analyses and the claims they make based on their research designs.

Just as @devezer.bsky.social posted today, there is still much to do to spread the world beyond the online bubble.

I believe many people are unaware of common pitfalls, such as the table 2 fallacy (interpreting individual regression coefficients causally) and/or might have never heard about "collider bias", which @vtraag.bsky.social illustrates here.

Happy to share our recent article on causal inference in science studies. It aims to introduce causal thinking to the science of science community with an example from Open Science.
