Reddit commenter on Bayesian odds and the Rootclaim COVID origins debate
Looking at the probability table blackpills me on trying to use bayesian odds when forecasting or giving probabilities to any non-trivial claims. It just seems like a fractal mess, where the further into the details of any part of the evidence you can find more and more coincidences or inconsistencies that (if you give them any weight) start drowning out any signal of what the most important evidence is. [...] But what are we even doing if on just one piece of evidence (i.e. row in the table) the bayes odds can vary over 100x on the people who consider it, and some people don't even consider it!

Statement relation comments

AI Verified Relevant: in the Reddit thread, the quote is explicitly about the COVID-origins debate’s "probability table" and use of "bayes odds," and the author says this makes them pessimistic about using Bayesian odds for non-trivial claims because judgments vary wildly. That directly addresses whether Bayesian analysis is the right framework for settling this question and makes opposition substantially more likely.

AI Verified He is mostly rejecting the approach: the table 'blackpills me on trying to use bayesian odds' for 'any non-trivial claims' and he asks 'what are we even doing' when one row can shift the odds by 100x across people. In this COVID-origins discussion, that strongly implies opposition to Bayesian analysis as the right framework for settling the question, even though he concedes it might be somewhat useful at a high level.
