> Wuhan is a massive city and economic hub Let's dig into this a bit more though. The WIV's location on Google Maps apparently changed after the incident [1]. I don't know if it was a legitimate correction or what, but for the sake of argument let's suppose that the old location was correct. Then the lab is 8.6 miles from the wet market, or ~14 km. It looks like the population density in that area is around 10,000 pe…
Your prior is also exactly what you're trying to calculate, though. I don't think you can just try different numbers picked from a hat for that value. Also, it isn't accounting for lots of other highly relevant, potentially confounding variables. And those assumptions make no sense to me at all. Can you write them out much more explicitly? I think it's totally plausible it was a lab escape, but this analysis seems ex…
Maybe I should have been more explicit, but they're not the same. The prior here is the probability that the virus originated from WIV, knowing only that the virus originated in China, and not accounting for the location of the outbreak. I'm trying to calculate an adjusted probability given the outbreak location.

My goal was not to convince anyone that a prior of 1% or 0.1% is appropriate, but rather to suggest a framework in which people can insert their own priors.
And sure, it's a simplified analysis, but it's better than just asserting whatever our intuitions say about coincidences.
