Twitter revolutionised my career.

I learnt a huge amount about causal inference through #EpiTwitter.

And I met many amazing people who I've since had the joy of working with (Eg @epiellie.bsky.social, @epidbydesign.bsky.social, @robertwplatt.bsky.social, @jlrohmann.bsky.social, etc etc)

Two things of note in today's announcement of the 2025 Nobel physics prize (besides the work being honored).

1: The US institutional dominance of the prize continues.
2: 2 of the three laureates are immigrants, drawn here decades ago by the then-unmatched opportunities for science here...

In Germany, probably Austria too, there are so many Associate Professorships (W1, sometimes even W2) without tenure track that it is worth mentioning if you are on a tenure-track position.

My main problem with this is not so much the dominance of quantitative methods in “top-20” journals but rather the dominance of the exclusive use of quantitative methods — in many cases causality could and should have been established by a (nested) qualitative study. *

I guess the mechanism is not clear. Could be randomization levels the playing field and diversifies pool of recipients, or that more researchers feel encouraged to submit who would have also got funded without randomization. In either case, randomization seems to have a diversifying effect 2/

Just finished reading this *excellent* article by Gabriel et al. which discusses which effects can be identified in randomized controlled trials. With DAGs!>

link.springer.com/article/10.1...

Elucidating some common biases in randomized controlled trials
using directed acyclic graphs

Although the ideal randomized clinical trial is the gold standard for causal inference, real randomized trials often suffer
from imperfections that may hamper causal effect estimation. Stating the estimand of interest can help reduce confusion
about what is being estimated, but it is often difficult to determine what is and is not identifiable given a trial’s specific
imperfections. We demonstrate how directed acyclic graphs can be used to elucidate the consequences of common imperfections,
such as noncompliance, unblinding, and drop-out, for the identification of the intention-to-treat effect, the total
treatment effect and the physiological treatment effect. We assert that the physiological treatment effect is not identifiable
outside a trial with perfect compliance and no dropout, where blinding is perfectly maintained

Table 1 showing the Identifiability of target estimands depending on whether there is blinding, full compliance, and no drop-out

An example DAG from the paper.
Fig. 4: A blinded trial with noncompliance.

U are unobserved confounders, Z is treatment assignment, C is compliance, X is the realized treatment, S is the subject's physical and mental health status, Xself and Xcln are the treatment that the participant and the clinician believed the participant received, Y is the outcome.

I think this mostly explains why tables remain dominant (in my experience): Researchers are primarily trained in showing and interpreting tables, so one keeps asking for tables in regression articles. One can show them in an appendix, but there is little reason to waste article space on a table. 1/

A lot of psych is already conducted with online convenience samples & ppl are probably excited about silicon samples bc it would allow them to crank out more studies for even less 💸

How about we reconsider the idea that sciencey science involves collecting own data.

AI-generated ‘participants’ can lead social science experiments astray, study finds

Data produced by “silicon samples” depends on researchers’ exact choice of models, prompts, and settings

I hope the #PhilSci crowd can help: I remember a paper discussing absences in causation. It has on the first pages a 2x2 table relating presence/absence of cause and effect to each other. Probably from 2000s, or 2010s. I remember neither title nor author, I hope someone knows what I am talking about
