The most similar thing I know about personally is military contingency plans. My dad was a Marine Corps officer and, among other things, worked on contingency plans in the late 1960’s. There are standing contingency plans for almost every conceivable military operation the US might perform, ranging from amphibious landings on the fjords of Norway to capturing any given small Caribbean island. The plans don’t always get followed, though. My dad spent a lot of time developing a contingency plan to capture the island of Grenada, and he spent the rest of his life bitterly insisting that his plan was far better than how that operation actually turned out!
His main complaint was that the actual operation used an unnecessarily large cross-service force (largely for political reasons; the Air Force and Army didn't want to miss out on the chance to get involved) when his plan required less than a division of Marines with accompanying air support.
The contingency plans themselves are highly classified, and none of the plans nor the associated maps and whatnot are allowed to leave a specifically secured facility, making this one of the few times in his military career that my dad couldn't just take home his paperwork at the end of the day. In the case of the Grenada plan, there was already an existing plan that is reevaluated and updated with new intelligence, doctrine, etc. on a periodic basis.
One detail of the plan my dad mentioned investigating was a standing tank (i.e. a large barrel for storing liquids) in the middle of a field on the island. The old plan entailed securing the tank and using it as temporary fuel storage, but my dad was suspicious. It turns out the tank was in the middle of a sugar cane field. It was a molasses tank. Probably not safe or feasible for fuel storage.
Even writing this out, I find this story a little hard to believe, but that's the level of detail the military, at least, puts into their contingency plans.
I think it is simply he chooses not to understand in favor of gut instinct and even what he last read / saw on TV.
Like you said I don't want to go down the rabbit hole, but I think there's a difference between trying an unable and simply choosing not to try understand a thing (for whatever reason that is).
I am pretty sure it is lack of ability. Some of the reported interactions between him and other world leaders is pretty alarming. For example, Merkel of Germany had to tell him 11 times that he could not negotiate trade deals between the United States and Germany because Germany is part of the EU. (http://www.businessinsider.com/trump-trade-merkel-germany-eu...)
He uses his gut instinct all the time because that is all he has.
I mean, the guy can't even read.
How likely is it that current leaders heed their advice when an outbreak happens? Wouldn't it be more useful to have the people currently in power preparing for this?
Honestly asking - I have no idea about the modus operandi of Washington bureaucracy.
