Earlier quoted context omitted.
The practice is not the “do good science using the correct methods”. The practice is “call for increased education spending for *waves hands* reasons”. Listen, this is the old Internet trick: people show up demanding rigorous models and evidence when they see something they don’t like, but what they like they demand nothing of.
That's ... not a fallacy. It's simply extraordinary claims require extraordinary evidence in action. (Eg. if your Bayesian prior is already edukashion gud, and someone says giv muniez to teacherz, you can say yes, ok, dollar. But if someone says no no, it's a waste of resources you can say okay the burden of proof is on you now, have fun.)
Since the prior is uninformed, it's obvious this isn't "extraordinary claims require extraordinary evidence" since both claims are extraordinary. It’s just that one is political desirous. Ain’t fooling nobody with the attempt at rational cover.
