The committed Rationalists often point out the flaws in science as currently practiced: the p-hacking, the financial incentives, etc. Feeding them more data about where science goes awry will only make them more smug.
The real problem with the Rationalists is that they* think they can do better*, that knowing a few cognitive fallacies and logicaltricks will make you better than the doctors at medicine, better than the quantum physicists at quantum physics, etc.
We need to explain that yes, science has it's flaws, but it still shits all over pseudobayesianism.
I'm sure they could have found someone in the EA ecoystem to throw them money if it weren't for the fundraising freeze. This seems like a case of Oxford killing the institute deliberately. The 2020 freeze predates the Bostrom email, this guy who was consulted by oxford said there was a dysfunctional relationship for many years.
It's not like oxford is hurting for money, they probably just decided FHI was too much of a pain to work with and hurt the oxford brand.
