Ah, if only the world wasn't so full of "stupid people" updating their bayesians based off things they see on the news, because you should already be worried of and calculating your distributions for... inhales deeply terrorist nuclear attacks, mass shootings, lab leaks, famine, natural disasters, murder, sexual harassment, conmen, decay of society, copyright, taxes, spitting into the wind, your genealogy results, comets hitting the earth, UFOs, politics of any and every kind, and tripping on your shoe laces.
What... insight did any of this provide? Seriously. Analytical statistics is a mathematically consistent means of being technically not wrong, while using a lot of words, in order to disagree on feelings, and yet saying nothing.
Risk management is not a statistical question in fact. It's an economics question of your opportunities. It's why prepping is better seen as a hobby, a coping mechanism and not as viable means of surviving apocalypse. It's why even when a EA uses their super powers of bayesian rationality the answer in the magic eight ball is always just "try to make money, stupid".
So, actually, many people were thinking about lab leaks, and the potential of a worldwide pandemic, despite Scott's suggestion that stupid people weren't. For years now, bioengineering has been concerned with accidental lab leaks because the understanding that risk existed was widespread.
But the reality is that guessing at probabilities of this sort of thing still doesn't change anything. It's up to labs to pursue safety protocols, which happens at the economic edge of of the opportunity vs the material and mental cost of being diligent. Reality is that lab leaks may not change probabilities, but yes the events of them occurring does cause trauma which acts, not as some bayesian correction, but an emotional correction so that people's motivations for atleast paying more attention increases for a short while.
Other than that, the greatest rationalist on earth can't do anything with their statistics about label leaks.
This is the best paradox. Not only is Scott wrong to suggest people shouldn't be concerned about major events (the traumatic update to individual's memory IS valuable), but he's wrong to suggest that anything he or anyone does after updating their probabilities could possibly help them prepare meaningfully.
He's the most hilarious kind of wrong.
