📣Our 🆕 paper Causal Inference is Not Just a Statistics Problem is out! @malco_barrett, @travisgerke, and I show that you can have 4 data sets with identical summary stats & visuals but very different data generating mechanisms-statistics alone can't tell you what to adjust for!

So much discussion of statistical methods is centered on case analysis like "is your output value discrete or continuous?" or "is your output always positive?" But my experience is that the most important question, "does your data behave like a IID sample?", is just not asked.

I want to do a follow-up to the blog series above, focusing on confounded mediation. But until I can get that done, please accept the prior art and join me in the humble epistemic stance of: If we don't state how the variables influence one another, we can't infer anything.

“To say that the world consists of qualities does not entail or imply that it consists of the qualities of our perception.” @BernardoKastrup writes on the demise of scientific materialism and what the view of reality as made up of consciousness entails. iai.tv/articles/reality-is-n…
