Statement relation comments

AI Verified Relevant: the quote is explicitly a Bayesian comparison of competing COVID-origin hypotheses (A vs. Z), and the surrounding article treats Bayes factors plus priors and other likelihood factors as the way to form net odds and evaluate the origins question. That makes the author’s stance on the complete statement substantially more likely to be determinable.

AI Verified The source URL is fetchable and contains the sentence "Combining all Levin’s spatiotemporal Bayes factors gives a net factor of 15,000 favoring A over Z." in the post "Big News on Covid Origins," bylined "Michael Weissman" and dated 2025-02-03; the only difference from the submitted text is typographic apostrophe normalization (Levin’s vs Levin's). Michael Weissman’s Substack profile and the University of Illinois profile for Michael B Weissman corroborate that this is the same author.
