This post primarily centers around a comprehensive 2022 case study conducted by Markus Stoffel and colleagues (Stoffel et al., 2022). This information dense paper is notable for its integration of a literature review and the combination of data from diverse sources and historical records.

Existential Crunch is a living literature review about societal collapse. When I read new things, which update my views, I’ll also update my posts (1). This post highlights updates I made to three posts. However, before we dive into the changes, I have a little announcement: It’s been six months already since I started this project for real. Since then I have published five posts for the living literature review and two posts about other topics.

In the last year nuclear winter was a topic I spent a lot of time on. It is one of the potential global catastrophes that motivates me in general and it is directly relevant to my work (Jehn, 2023; Jehn et al., 2023). This makes it kind of obvious that I take nuclear winter seriously.

The risk of societal collapse is dependent not only on the problems a society faces, but also on the adaptation it makes to counter those problems. These adaptations can increase the resilience of a society and make it less vulnerable to potential hazards.

I created a list of researchers in the existential risk field based on the amount of papers they have published. In the following I provide links to their work. This is not meant as a strict evaluation of the value of their contributions to the field, but more as a quick overview of who is working on what.

If we want to learn about human society’s resilience or fragility, it’s helpful to learn from our species’ prior experiences. The trouble is, since collapse is a relatively rare phenomenon, we’re short on data.

Environmental changes can put considerable strain on a society and there are many cases in history where it was a major contributor to their collapse, especially when the change was sudden.

Going forward this blog here will work somewhat differently. I got some funding by Open Phil to start a living literature review on societal collapse (thanks to Matt Clancy for making this happen).  So how is this gonna work? The idea behind this project is to make research on societal collapse more accessible to anyone who’s interested in the topic, by writing it up in a nicely sorted and easy to read way.
