Watching Doomsday Preppers

Google it if you need to. I'm not going into details. My psychologist sister in law thinks the show exploits the mentally ill, but I enjoy it.

Besides, in the spirit of Szasz perhaps those sorts of concerns are themselves condescending.

Here's my question: how should we partition this behavior between (1.) extreme risk aversion, and (2.) inaccurate assessments of the probability of doomsday?

Szasz types would probably err on the side of (1.). I don't see how you can watch these people explain their thinking without putting the bulk of it on (2.). If we were talking bomb shelters in the Cold War there's probably a lot of room for (1.), but not in most of these cases.
