I remember listening to part of an radio interview about Ben Bernanke's response to the 2008 Financial Crisis being sort of a wild guess which ended up averting an even worse disaster possible. This was one story in a book about times decisions changed the course of history of something along those lines, and I'm pretty sure came out in 2019 but can't remember for sure.
I think it was on Canadian Public Radio show, they tend to play late at night here in the northern US
