This discussion is about methods to overcome adverse events and challenges so that (1) you don't panic when they hit you, and (2) you're not traumatized afterwards.
There's little explanation about how to do it, but it was enough for me to pattern-match it with "rationality sub-skill". It looks like a training for not losing your rationalist powers when you most need them. Or at least remember to "stick them with the pointy end".
That said, maybe CFAR already teaches some of that?
