We have to stop this narrative that we aren't going to listen to people until they are infallible. That's not how crisis management works. Or war, football, basketball, card games...
Hedging your bets is the act of wasting resources constructively, so that if your worst case scenario happens, you aren't doomed. Faulting people for hedging their bets is going to get us all killed.
It's been happening to scientists (first climate, now everybody) for years, and 'getting us all killed' was more figurative. Now we're doing it to doctors, and people are in fact dying. Of Covid (655k so far). Of measles (140k in 2018).
Do you want a dark age? Because this is how you get a dark age.
