Me at work: you shouldn’t condition on posttreatment variables as it biases inferences, see Montgomery et al. (2018).

Me at home: look at how sweet the kids are with each other when they’re not fighting!

Do you think that learning more about causal inference is not worth it because you're running experiments anyway, or because you're interested in predictive questions? In that case, I've written a paper just for you, out now in SPPC: compass.onlinelibrary.wiley.com/doi/10.1111/...
Causal inference for psychologists who think that causal inference is not for them. Correlation does not imply causation and psychologists' causal inference training often focuses on the conclusion that therefore experiments are needed—without much consideration for the causal inference frameworks used elsewhere. This leaves researchers ill-equipped to solve inferential problems that they encounter in their work, leading to mistaken conclusions and incoherent statistical analyses. For a more systematic approach to causal inference, this article provides brief introductions to the potential outcomes framework—the “lingua franca” of causal inference—and to directed acyclic graphs, a graphical notation that makes it easier to systematically reason about complex causal situations. I then discuss two issues that may be of interest to researchers in social and personality psychology who think that formalized causal inference is of little relevance to their work. First, posttreatment bias:... DAG illustrating posttreatment bias which can be induced in randomized experiments whenever researchers condition on posttreatment variables Figure illustrating various reasons why demonstrations of incremental validity may be unimpressive: established predictors are omitted, measurement error is ignored, only little predictive utility is gained

Just from the parts that you posted, this is *very* clearly conditioning on a posttreatment variable in a manner that can obviously create the “effect.” Excluding students who aren’t motivated and willing to engage increased motivation and engagement.

(A) Mean change and (B) mean percent change in CLASI-A scores from baseline for afimetoran versus placebo over 20 weeks. Baseline is the last nonmissing results with a collection date/time less than the date/time of the first dose of study medication. In (A), values next to number of patients represent adjusted mean change from baseline (SE) for afimetoran or placebo. In (B), values next to number of patients represent adjusted mean percentage change from baseline (SE) for afimetoran or placebo. The blue-shaded area represents the posttreatment follow-up period. BL, baseline; CLASI-A, Cutaneous Lupus Erythematosus Disease Area and Severity Index-Activity; QD, once daily.

I believe they calculated their means for each group as follows: baseline/pretreatment (green) minus posttreatment (yellow). They then calculated SMDs for these differences in means, which leads to the reported means for several studies.

I get the logic of the limitations statement ---how can someone be affected if they don't comply with the treatment---, but this seems like a typical example of how "Conditioning on Posttreatment Variables Can Ruin Your Experiment" (doi.org/10.1111/ajps...)
Finally, as pre-registered, participants in the experimental group who listened to less than 20% of the audio-learning materials were excluded from the analysis. This decision was made to evaluate the audio-learning modules’ efficacy among those who actively engaged, as including non-engaged participants would conflate the effects of the intervention with a lack of exposure. Additionally, including non-engaged participants would create an unfair comparison with the control group, as their lack of engagement would align them more closely with controls than active users. However, it is worth noting that individuals may have different learning preferences, and audio-based learning is not effective or appealing for everyone. The exclusion of approximately half of the participants in the experimental group suggests that the audio-learning modules may not have been sufficiently engaging for all students. Future studies should explore strategies to improve engagement, while also considering individual learning preferences and identifying the factors that influence why some students choose to engage and others do not.

One test I’ve been considering is the most old fashioned but tried and true: show the results both ways and reflect on implications of results. At very least, we can’t just declare posttreatment control or confounding on assumptions alone.

I worry a bit the pendulum has swung such that people are excusing themselves from adjusting for plausible confounders by declaring the threat of posttreatment control bias.

Then they show some surprising or contrarian or flashy finding that only holds up if you omit what we used to control for.
