Multiplying the share of markets (1 and 2) by the share of HSM within markets (3), we converge to around 3-5%.

AI Verified The quote is relevant because, in source context, it is a concrete step in the article’s Bayes-factor style COVID-origins analysis: the author is estimating a conditional probability for an HSM spillover under zoonosis, immediately after framing the dispute in terms of comparing conditional probabilities/Bayes factors and presenting that as the proper way to analyze the question. That makes the author’s stance on the complete statement substantially more likely to be determinable.

AI Verified Relevant: in context, this quote is part of the source’s explicit Bayes-factor/conditional-probability analysis of COVID origins, using a numerical estimate for p(HSM|Zoonosis,Wuhan). That makes support for Bayesian analysis as the proper framework substantially more likely. ([blog.rootclaim.com](https://blog.rootclaim.com/)) · YouCongress gpt-5.4-2026-03-05 · 3mo ago

AI Verified The quote itself is a Bayesian-style conditional-probability estimate ('we converge to around 3-5%'), and the surrounding article says COVID-origins evidence should be evaluated by 'the ratio of the conditional probabilities'/'Bayes factor' and calls that 'the best way to approach this question.' That strongly implies support for Bayesian analysis as the right framework here.

AI Verified The quote itself is a Bayesian-style likelihood estimate (HSM spillover/cluster "around 3-5%"), and the source explicitly says COVID-origins evidence should be evaluated by Bayes factors and by "learning how to do probabilistic inference correctly," presenting that methodology as superior for reaching the conclusion. That strongly implies the author sees Bayesian analysis as the proper framework for deciding the question.

Bayesian analysis is the right framework for settling the COVID-19 origins question

Finally, we’ll try to quantify the conditional probability of an HSM spillover and early cluster, assuming zoonosis as the origin and Wuhan as the location, given this data:

The clustering of early cases around the Huanan market reflects where the COVID-19 virus emerged, not just where testing looked

The HSM early cluster is therefore negligible as evidence. Our analysis assigns it 2x.

COVID-19 originated from a lab-related incident rather than natural zoonotic spillover

Zoonosis is a more likely hypothesis due to being better supported by the evidence – This is completely untrue, but to fully understand it one has to commit to learning how to do probabilistic inference correctly, which Scott could not free enough ti...
