Kulldorf's at Harvard so he presumably has/had some chops. But it also means he's got to bring in the flow, not just public funding agency flow but deep pocket flow. He's one of the Barrington Declaration people. Its interesting that it seems to me epidemiology draws from at least two different groups, which can tend to have different political leanings. There's immunology with a kind of medical let's help people orientation and then the more mathematical side of epidemiology which can be pretty pure Darwinian in it's outlook. So in Kulldorf's case he gets a lot of support from conservative economic think tanks. And of course there will be the left wing equivalent of that. All well and good in terms of academic debate that can be considered by policy makers I guess. But its also the sort of thing that affords low hanging fruit in the infodemic, ready made to order tweets that can be picked up and sprayed out all over the internet by whatever actors are driving this. And in Kulldorf's case if you bother to circle back and click I'm sure it helps sell his book. Notoriety is good.
