It is good to see the move on Bluesky because, X was starting to be boring. Nice to e-meet so many new followers here. Here is a 🧶 that is introduces most of my research interests. It is about #metaresearch #openscience and #medicine.

Its an art to be so stringent and so clear with such limited amounts of words. Just found this one from 2010 through googling Alains name. Is "T2A" still in work in France?. www.bmj.com/content/340/...

New expression of concerrn in @bmj.com possibly causing waves of concern among Swedish scientists who earn their careers by harvesting the formidable Swedish registries. When its not ok anymore to assume causal effects in observational trials where will be the fun left?

No significant effect for ketamine (vs midazolam) in this trial. This contrasts previous research. Functional unblinding and reduced expectancy effects due to the enrolment algorithm likely explain this finding (implying that older research is biased).

Science is grounded in observation. Measurement is a tool for observation. Measurements should be evaluated for validity and reliability/uncertainty. Scientists who use measurements without understanding their properties are not really scientists at all.
Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.
One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.
