MD, PhD, MAE, FMedSci, FRCP, FRCPEd.
It is, I think, evident to anyone reading his comments on my recent post that Dana Ullman adores my little ventures into AI. In order to please Dana even more, I tought of doing another, more focussed and arguably more telling post on an AI analysis of his work.
As it seems a little unfair to compare someone who has done research in many different areas to someone who has focussed merely on one single subject, I decided to ask AI to compare Dana’s research output on his favorite (and only) topic, homeopathy, to mine on the very same subject. Specifically, I asked ‘ChatGPT’ the following questions:
Who has published more scientific papers on homeopathy, Dana Ullman or Edzard Ernst? And whose papers on homeopathy are more respected by the scientific community?
Here is the response AI gave me:

Here’s a data-based comparison specifically focused on scientific papers on homeopathy by Dana Ullman and Edzard Ernst — including quantity and scientific respect/impact.


🧾 1. Quantity of Scientific Publications on Homeopathy

📌 Dana Ullman

From PubMed and scholarly databases:

  • Dana Ullman has authored scientific papers that mention or discuss homeopathy, including:

    • An analysis of four government-funded reviews of research on homeopathic medicine (2021) — a review about homeopathy evidence.

    • Exploring possible mechanisms of hormesis and homeopathy (2021) — a review proposing mechanisms for homeopathy.

    • Controlled clinical trials evaluating homeopathic treatment in people with HIV (2003) — review of trials.

  • Overall, Ullman has a handful (~a few) peer-reviewed homeopathy-related papers indexed in PubMed. A precise total would require a database search, but it’s clearly in the low dozens or fewer in mainstream medical/biomedical indexes.

Many of Ullman’s writings on homeopathy are books, commentaries, or advocacy pieces outside conventional scientific journals. These don’t necessarily count as original peer-reviewed scientific research in standard scientific metrics.


📌 Edzard Ernst

Edzard Ernst has a long research career in complementary and alternative medicine, including homeopathy. Examples from PubMed:

  • Multiple original research and review papers focusing on the evidence base of homeopathy and clinical evidence — e.g. A systematic review of systematic reviews of homeopathy (2002).

  • Clinical and methodological pieces about homeopathy in high-impact journals (e.g., Homeopathy: What Does the “Best” Evidence Tell Us?).

  • Other papers addressing clinical and methodological aspects of homeopathy (e.g., Is homeopathy a clinically valuable approach?).

  • Editorials and commentaries examining the evidence base and plausibility of homeopathy.

Ernst has numerous peer-reviewed publications on homeopathy, spanning systematic reviews, meta-analyses, clinical evaluations, and broader evidence surveys — likely dozens or more. For perspective, Ernst’s total scientific output exceeds 1,000 peer-reviewed articles overall, many addressing homeopathy during his complementary medicine research career.


📊 Summary — Quantity

Researcher Approx. PubMed-indexed homeopathy papers
Dana Ullman A small number (a few to ~10-20) of indexed homeopathy-related papers
Edzard Ernst Many more (likely dozens+) indexed papers addressing homeopathy or its evidence base

➡️ Edzard Ernst has published more scientific papers on homeopathy than Dana Ullman.


🧠 2. Scientific Respect & Impact in the Scientific Community

📌 Edzard Ernst

🔹 Widely recognized in evidence-based medicine for applying rigorous methods to evaluate complementary therapies, including homeopathy.
🔹 His homeopathy research is published in mainstream, indexed journals and is often cited in systematic reviews/meta-analyses.
🔹 His work is cited by other researchers and included in high-visibility evidence syntheses (e.g., Cochrane and independent systematic reviews).

Scientific consensus views his homeopathy publications as critical evaluations based on best-available evidence, contributing to the mainstream understanding that homeopathy lacks reproducible efficacy beyond placebo.


📌 Dana Ullman

⚠️ Many of Ullman’s papers on homeopathy tend to be advocacy-oriented or speculative (e.g., proposing mechanisms like nanoscale effects) rather than clinical evidence showing efficacy.
⚠️ His work is less frequently cited in mainstream medical research and less influential in systematic evidence evaluations compared to work by critics like Ernst or independent reviews.
⚠️ The broader scientific community does not generally regard homeopathy as effective, and Ullman’s conclusions supporting homeopathy are not embraced by most evidence-based researchers.


Final Comparison — Scientific Respect

Criterion Dana Ullman Edzard Ernst
Number of homeopathy papers (indexed, peer-reviewed) Limited Substantially more
Published in mainstream scientific journals Some, but fewer and often niche Many — mainstream medical and evidence-based journals
Influence on scientific consensus Low (largely advocacy) High (critical, evidence-based evaluation)
Citation impact in evidence syntheses Low High

Again, I ask my readers to forgive me for doing another childish hoax.

But please understand: what would I not do to please my friend Dana!?!

5 Responses to More on Dana Ullman’s superb publications on homeopathy

  • Maybe Mr Ullman could use AI somehow to identify the laboratory that can distinguish homeopathic water from other water, which I have asked him to do 98 times in here after he called doubters ‘liars or fools’ (others have also asked). I am beginning to suspect – just beginning, mind you – that he does not do it, because he cannot.

  • Isn’t this in effect your 99th time of asking?
    Will Edzard write a blogpost on the occasion of the 100th time of asking?
    I can’t wait.

    • You are right, the 99th! Let us see if the centesimal request proves potent…… I guess I will stop at 1C. I don’t have the energy to go to 30C. Maybe I haven’t been succussed enough.

  • Great Edzie…are you next gonna compare the sizes of our hands or feet…and whatever THAT means. What limit does your machisimo have?

    I didn’t know that the number of publications was a competition.

    Perhaps we should count the number of people each of us has healed in a significant way…

    Competition reflects insecurity…

    • We can count the number of people you’ve healed successfully on the thumbs of one foot, Dana. You can delude yourself that you’ve done something significant whilst the patient has got better on their own but we know the truth.
