They've certainly turned out different than Scott Alexander predicted, once the markets were opened up to people who are not in the wider rationalist community.
Not foreseeing the amount of sports betting that would take place, is kind of a failure of rationality in the first place, and I say this as someone who absolutely respects the community in general.
>once the markets were opened up to people who are not in the wider rationalist community.
It's important to remember that for a brief time, people argued that gatekeeping was generally and usually a bad thing.
The failure of the rationalist community is they mistook rationalization for rationality.
They didn't foresee the amount of sports betting that would take place because sports betting was illegal almost everywhere in the US until 2018.
You should have lost your respect for the "rationalist" "community" a long time ago. They are aggressively wrong about everything, and most of them are eugenicists.
