I did fake Bayesian math with some plausible numbers, and found that if I started out believing there was a 20% per decade chance of a lab leak pandemic, then if COVID was proven to be a lab leak, I should update to 27.5%, and if COVID was proven not to be a lab leak, I should stay around 19-20%
This is so confusing: why bother doing “fake” math? How does he justify these numbers? Let’s look at the footnote:
Assume that before COVID, you were considering two theories:
- Lab Leaks Common: There is a 33% chance of a lab-leak-caused pandemic per decade.
- Lab Leaks Rare: There is a 10% chance of a lab-leak-caused pandemic per decade.
And suppose before COVID you were 50-50 about which of these were true. If your first decade of observations includes a lab-leak-caused pandemic, you should update your probability over theories to 76-24, which changes your overall probability of pandemic per decade from 21% to 27.5%.
Oh, he doesn’t, he just made the numbers up! “I don’t have actual evidence to support my claims, so I’ll just make up data and call myself a ‘good Bayesian’ to look smart.” Seriously, how could a reasonable person have been expected to be concerned about lab leaks before COVID? It simply wasn’t something in the public consciousness. This looks like some serious hindsight bias to me.
I don’t entirely accept this argument - I think whether or not it was a lab leak matters in order to convince stupid people, who don’t know how to use probabilities and don’t believe anything can go wrong until it’s gone wrong before. But in a world without stupid people, no, it wouldn’t matter.
Ah, no need to make the numbers make sense, because stupid people wouldn’t understand the argument anyway. Quite literally: “To be fair, you have to have a really high IQ to understand my shitty blog posts. The Bayesian math is is extremely subtle…” And, convince stupid people of what, exactly? He doesn’t say, so what was the point of all the fake probabilities? What a prick.
This makes me wonder, we know the Rationalists did worry about a global pandemic before COVID19, we checked the waste water and the smug particles increased exponentially for a short time in feb 2020. But did they also worry about a normal lab leak like which might have happened here? Or was it all either nature/terrorism/AGI stuff?
For a while there, when it looked as if only the rich were gonna be able to source R95 masks and everyone else was gonna die, the SV elite were all aboard with this being the new Black Death. As soon as it became apparent that the only way to deal with it was through massive government support they did a 180 and started talking about how it wasn’t that bad after all.
I’m myself just annoyed that the other Scott (no not the cartoonist, the other smart Scott) blamed sneerers for covid being worse. (while sneerclub itself was agreeing with the Rationalists that people should be careful and that it wasn’t a non-event). And that this Scott above argued that people should stop smoking to help against covid (not that he had any proof for that, he just disliked that people smoke (yes as good Bayesians we should now increase our ‘is the Rationalist thought leader lying to me’ priors)). The rest I don’t really recall that much.
“priors updated” was the same desired outcome all along.
Goddamn rats and their smug particles! (jk)
Anyone remember the South Park episode with the Prius emitting clouds of Smug?
