Against Learning From Dramatic Events

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:

  1. Lab Leaks Common: There is a 33% chance of a lab-leak-caused pandemic per decade.
  2. 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.

    and often the fact that you hear about it at all means the movement is fumbling it less than other movements that would keep it quiet

    I just can’t get over how far this is from reality. like fuck, for a lot of these things the controversy is the community covering for the abuser, or evidence coming out that sexual harassment was covered up in the past. depressingly often in tech, the community doesn’t even try to keep it quiet; instead they just loudly endorse the abuser or talk about how there’s nothing they can do.
