New publication: Trump’s statements about acetaminophen and the problem of epistemic corrections
A new article by Federico Germani, Giovanni Spitale (IBME), and Art Caplan has been published in BMJ Evidence-Based Medicine. The paper examines the public reaction to Donald Trump’s claims linking prenatal acetaminophen use to autism and uses the episode to explore a broader challenge: how scientific misinformation should be corrected.
The authors argue that many rebuttals framed the statement as simply “false,” overlooking a crucial epistemic distinction between falsehood and lack of justification. While current evidence does not support a causal link, the claim’s primary flaw lies in its unreliable reasoning and absence of methodological grounding rather than in demonstrable falsity alone.
The article calls for a shift in public health communication—from categorical fact-checking toward explanatory corrections that clarify how scientific knowledge is produced, why certain claims are unwarranted, and how uncertainty is managed. Such an approach, the authors suggest, is essential for sustaining public trust, especially as evidence evolves.
