Peter Turchin: Is a Societal Collapse Looming for America? (Transcript)

Read the full transcript of Russian-American complexity scientist Peter Turchin’s interview on Daniel Davis / Deep Dive Podcast on “Is a Societal Collapse Looming for America?”, September 2, 2025.

Introduction

DANIEL DAVIS: Is the United States of America, the home of the free, the land of the brave, heading towards a societal collapse? Is that even possible? Or is this just some hyperbole that a lot of people say a lot of things bad can happen, but it’s never going to happen here?

Sure, we may have our troubles here and there, but the resilience of our nearly 250-year-old country certainly is going to withstand anything like that. Or is there maybe more warning signs that we need to be paying a lot of attention to to make sure that doesn’t ever happen?

We couldn’t have a better guest on today. To try to cut through some of this, we have Peter Turchin, who is a Clio Dynamics and Social and Cultural Evolution project leader, Complexity Science Hub in Vienna, and a professor at University of Connecticut who has recently written a book called “End Times,” which we’re going to get into a little bit today. Professor first of all, welcome to Daniel Davis Deep Dive. A pleasure to have you on today.

PETER TURCHIN: Thank you for inviting me, Daniel.

The Science of History

DANIEL DAVIS: Well, listen, one of the things that really kind of stood out in some of the things that you’ve written, and then I’m actually going to cheat a little bit here and go straight to something that you wrote. I think it’s in the preface of your book.

You wrote: “History is not just one damn thing after another,” British historian Arnold Toynbee once quipped in response to a critic. For a long time, Toynbee’s opinion was the minority. Historians and philosophers, including famous ones like Karl Popper, vehemently insisted that a science of history was impossible.

Our societies are too complex, humans are too mercurial, scientific progress cannot be predicted, and culture is too variable in space and time. Kosovo is completely different from Vietnam and antebellum America can tell us nothing about the America of the 2000s. This has been and largely still is the majority view. I hope this book will convince you that view is wrong.

Why is that view wrong?

PETER TURCHIN: Well, because why shouldn’t we have a science of social evolution and social dynamics? There are arguments against it, which you have just listed, that humans are too mercurial, that cultures are too different, and many others could be applied pretty much to any other science, such as physics, for example.

I mean, think about Newtonian mechanics. Each planet is different. They have different mass, different color, different distance from the sun, and so on and so forth. Nevertheless, we can abstract from those differences and write general laws of motion. Same, I argue that same with human societies.

Yes, without doubt Vietnam is different from United States. However, if you look at the organization of our societies from a more abstract point of view and in more general terms, you will see that we are at that level. We are organized in very similar ways.

So think about my favorite example is the Spanish conquistadors. Like Pizarro, for example, they arrived in Peru or Cortes in Mexico, and they immediately saw kings, nobles, priests, peasants, temples, and so on and so forth. So these societies have developed completely separately from European societies that Cortes for example, knew. However, they were at some level organized in very similar ways.

And so our science is the name of the Greek muse of history. So it basically means historical dynamics. Dynamics is a science of change. So we are studying how societies change by throwing the good old scientific method at it.

So the problem so far with historians, which is I have huge respect for historians and history, it’s a wonderful profession, it requires high sophistication from its practitioners to read medieval Latin manuscripts or from archaeologists to discover facts about past societies. And they provide explanations. So they have theories and hypothesis about, let’s say, why Roman Empire fell.

Unfortunately, one German historian counted the explanations for the fall of the Roman Empire and he found there were 240. And since then there is probably 300 of them. So unlike in physics or biology, historians propose hypothesis in theories, but they don’t do the next critical step, which is eliminate use data to eliminate bad explanations versus good explanations. And that’s what cliodynamics attempts to do.

Lessons from the Roman Empire

DANIEL DAVIS: And I mean, I’ll just ask that question there. What is your scientific study of history? What has it shown you about the Roman Empire? Is there like a concise answer to which of those 240 some odd are right or wrong?

PETER TURCHIN: So yes, in fact. Well, let’s ask how can we study such things as the collapse of the Roman Empire? So if you only study the Roman Empire by itself, you have a sample size of one. All right, and that is very difficult at those statistics.

So what we do, what do we collect data not just in Roman Empire, but on all large scale complex societies. All right, so in our database you have data for hundreds of them. And we studied their crisis periods which they enter using this database.

And this database records a variety of variables that change in the pre crisis periods. And different theories make predictions about different drivers for crisis. And therefore they identify different variables that should change in a regular way before crisis. So that’s how we capitalize on historical data.

And so in the book “End Times” that you mention, actually present the theory that explains in general why complex societies inevitably, after some time, enter these periods and times, periods of political disintegration, social turbulence, high political violence.

And the outcomes could be quite variable, ranging all the way from utter collapse to in fact, some positive outcomes, when the elites and the populations manage to cooperate together to avoid the really bloody outcomes, revolutions and civil wars.
