Modelling the odds of recovery from civilizational collapsepost by MichaelA · 2020-09-17T11:58:41.412Z · score: 26 (11 votes) · EA · GW · 5 comments
This post outlines an idea for a research project. I think someone should do something like this, and there’s a ~50% chance I will at some point. I’m publicly sharing this idea in order to:
- Highlight this potentially important question/crux
- Get feedback
- See if there’s anyone else who might want to do a project along these lines
- Make coordination, and avoiding duplication of work, easier
Feel very free to comment here, message me, and/or schedule a call with me.
Some experts and EAs appear to think there’s a nontrivial chance of civilizational collapse. Some further argue that reducing the risk of collapse, or increasing the chance of recovery, should be a top priority. Others argue that that wouldn’t be worth prioritising even if there’s a nontrivial chance of collapse, based on the premise that the chance of recovery is already high. The latter group might suggest instead prioritising reducing risks of extinction or dystopia [EA(p) · GW(p)], or prioritising things unrelated to existential risks [EA · GW]. Indeed, views on the odds of recovery from civilizational collapse seem to be pushing large (and growing) pools of money and talent either towards or away from work aimed at reducing collapse risks or increasing chances of recovery.
Advancing our thinking on that matter thus appears highly valuable. Furthermore, I see a way to do that that seems tractable and neglected. Specifically, I propose modelling the likelihood of various types of recovery from various types of collapse scenarios, following roughly the following steps:
- Think about how to carve up the possible causes of collapse (e.g. impact winter, pandemics), types of collapse (e.g. loss of population, industry, both), and types of recovery (e.g. recovery of GWP, political institutions, values), and think about what to focus on.
- “Likelihood of recovery from collapse” is underspecified, and some types of recovery from some scenarios may be unlikely even if others are likely.
- Begin to construct in Guesstimate one or more models of the odds of various types of recovery, given various collapse scenarios.
- Begin to estimate the parameters of this model(s).
- Iteratively refine the model(s), estimates, and conceptual underpinnings.
- Present the results in EA Forum posts, and possibly as a paper.
- Perhaps iterate further based on new feedback from the EA and academic communities.
Steps 1-4 could involve armchair reasoning; reading relevant academic and/or EA writings; and getting ideas and input from EAs and academics. I’ve previously collected sources relevant to this matter [EA(p) · GW(p)], and, if I were doing this project, I’d likely start by (re-)reading some of those sources and contacting some of their authors. I’d also read works from and talk to experts outside the global catastrophic risk field (e.g., experts on minimum viable populations or the history of the industrial revolution), especially when estimating parameters. I expect the output would resemble that of Rethink Priorities’ series on nuclear risks [EA · GW], and it might be useful to in some ways emulate how that research was conducted.
This project would be unlikely to provide definitive answers, but could plausibly inform our point estimates, narrow our uncertainty, indicate what further research would be most valuable, and suggest points for intervention.
It may also end up seeming worthwhile to (also) model the odds of various collapse scenarios occurring in the first place. However, that topic seems to me somewhat less neglected than the odds of recovery.

My thanks to David Denkenberger, Aron Mill, Luke Kemp, Siebe Rozendal, Ozzie Gooen, Seth Baum, and Luisa Rodriguez for their useful input on this research project idea. Also, this idea might have originally been inspired by Rethink Priorities indicating interest in [EA · GW] “Analyzing the likelihood of civilization recovering from a population collapse” (I can’t remember for sure). This does not necessarily imply any of these people’s endorsement of this idea or this post.
This post doesn’t necessarily reflect the views of my past or present employers.
I have a other project ideas I could pursue instead of this. And someone else might have a more fitting skillset for this than I do. So I’m potentially happy for someone else to take this project on instead of me. ↩︎
Maybe someone else is already doing, or would by default do, something similar to this. And/or maybe someone is doing something vaguely related, and they or I could benefit from us talking. ↩︎
