Recoilweb recently published a good article about the probabilities of unlikely events, The Surprisingly Solid Mathematical Case of the Tin Foil Hate Gun Prepper, and how it applies to the “zombie apocalypse”.
The 2018 article discusses the likelihood of a revolution or other major event happening, and how preppers are generally along the leading edge of surviving these events.
It does contain non-common core math calculations, so those who are triggered by such things would be best served by not reading it.
