The fundamental rule imo should be that the more absurd the claim, the more it deserves a double check. That hospitals are prioritising gunshots below ivermectin is absurd to what I hope is most people.
The fundamental rule is to double check everything. Otherwise you end up letting false stories through that confirm your preexisting biases, since they don't sound "absurd" to you.
