The Jurassic Critique of Micozzi on Evidence Hierarchies
AI21 Labs have just released a public demo of their giant language model, Jurassic-1. At 178bn parameters, it rivals GPT-3. Feeding it my own work, it generated some interesting and potentially novel views on evidence hierarchies… and then attributed them to CAM researcher Marc Micozzi! Is Jurassic Micozzi’s critique of evidential pluralism in medicine sound?
On the Global Summit: do critiques of evidence hierarchies favour chiropractic?

If so, does the evidence base favour chiropractic?

Random Reflections: Cochrane and the Origins of Hierarchies

It’s a fascinating gallop through the concerns of one of the most influential figures …
A Ghost of Progress – How Hierarchies Become Fixtures
I have written extensively on hierarchies of evidence in evidence-based medicine. The origin story of hierarchies of evidence is a little contentious. Several sources in EBM cite Campbell and Stanley’s 1963 classic “Experimental and Quasi-experimental Designs for Research” as containing the first hierarchy, or at least the germ of the …

Hierarchies of Evidence: Database of Hierarchies
Hierarchies of Evidence are a tool employed by many advocates of Evidence-Based Medicine. They are used to appraise evidence from a range of sources, as well as to teach medical students about evidence and evidence appraisal. My PhD thesis concerns the variation in hierarchies defended, and the range of philosophical interpretations of those hierarchies.
