Ian Hacking traced the origin of randomization in ‘empirical experimentation’ to the early days of the Society for Psychical Research, to precisely the place where it started, the place marked chiefly by complete ignorance.

Causal diagrams and counterfactual reasoning reach political sciences. Congratulations to Prof Jacobs UBC Political Science on the successful launch of his book!

The challenge of statistical science is obvious. But that's the difficulty of statistical science. Less obvious, however, is how the inability to develop a statistical method for estimating parameters discovered by causal analysis can undermine both the value of those parameters

The most important of Rubin's assumptions here is ignorability: if the untreated were treated, they would have the same outcomes as the treated.

This was, of course, brilliant at that time.

Judea Pearl got rid of the ignorability assumption by proving that ignorability follows

Adjusting for all known pre-treatment predictors of outcomes improves precision and efficiency of statistical estimators.

Adjusting for treatment predictors blocks factors that might cause covariation between treatment and outcomes.

Whether by stratification or inverse

Bruno, congratulations!

I need to learn from you the dialectic of measurement. I'm tired of the mindless empiricism in assessment and attribution within health research.

It’s true for any tool we ever created.

‘Nature does not build cars, locomotives, railroads, electric telegraphs, etc. These are the organs of the human brain, created by the human hand; the power of knowledge, 𝐨𝐛𝐣𝐞𝐜𝐭𝐢𝐟𝐢𝐞𝐝.’ —Karl Marx in Grundrisse, 1858

In medical research, a 'good statistician' is one who does exactly as they are asked & is able to produce 'a significant p-value'.

If, instead, you dare to ask difficult questions or point out flaws then you will be branded 'difficult to work with' and get exiled!

This school of stats practitioners continues to equate causal effect with the output of statistical analysis of RCTs, without explicitly specifying the estimand for their estimators.

In contrast, Judea Pearl first defines the causal effect as a target parameter of the

'Some papers' is just a sleight of hand by Frank Harrell. Badly done science doesn't invalidate the scientific method.

If someone can’t perform Rach-4, it doesn’t mean that Rachmaninoff wrote bad music.
