as someone who is working in ED in Australia, I can say that Lesswrong has been consistently predict the behaviors of my hospital management by 2-3 days.
for example: I’ve read a lesswrong post arguing that covid-19 is serious and people should stock up while my manager was still telling us to just calm people down if asked. The stance was reversed 2-3 days later.
Slatestarcodex recommended the wide spread use of masks a whole week before my local health district recommened the same thing.
I am not certain that being slow is not part of the system design. but Lesswrong has allow me to predict future hospital policies quite consistently.
