A hydrologist walks us through the cold mathematics of revolution and chaos:
While we don’t have any good sources of data on how often zombies take over the world, we definitely have good sources of data on when the group of people on the piece of dirt we currently call the USA attempt to overthrow the ruling government. It’s happened twice since colonization. The first one, the American Revolution, succeeded. The second one, the Civil War, failed. But they are both qualifying events. Now we can do math. […]
Stepping through this, the average year for colony establishment is 1678, which is 340 years ago. Two qualifying events in 340 years is a 0.5882% annual chance of nationwide violent revolution against the ruling government. Do the same math as we did above with the floodplains, in precisely the same way, and we see a 37% chance that any American of average life expectancy will experience at least one nationwide violent revolution.
This is a bigger chance than your floodplain-bound home flooding during your mortgage. [I.e. 26%]
It’s noticeably bigger.
And here’s a factoid that should give you pause for thought:
Since the fall of Constantinople in 1453, there have been 465 sovereign nations which no longer exist, and that doesn’t even count colonies, secessionist states, or annexed countries. Even if we presume that half of these nation-state transitions were peaceful, which is probably a vast over-estimation, that’s still an average of one violent state transition every 2.43 years.
Maybe the Silicon Valley billionaires, Hollywood celebrities and politicians who are secretly building apocalypse bunkers have rational reasons for doing so and are not completely nuts.
