Peter Turchin Quotes

[T]here are some reasons to doubt that growing inequality might be a direct mechanism... of instability, because humans are very bad at perceiving inequality. ...[A] number of studies ...show that people, when... asked to estimate the degree of income or wealth inequality... their opinions essentially have nothing to do with what is actually... measured by economists.

The SDT proposes that the causes of revolutions and major rebellions are... similar to processes that cause earthquakes. In both... it is useful to distinguish "pressures" (structural conditions, which build up slowly) from "triggers" (sudden releasing events, which immediately precede a social or geological eruption).

The theory represents complex human societies as systems with three main compartments (the general population, the elites, and the state) interacting with each other and with socio-political instability via a web of nonlinear feedbacks.

I'll use the example of the United States, which I have studied from inside out... over the past 20 years, and I will illustrate how these few forces... have laid out in real life... a particular example...

Using these trends as inputs, the model calculated and projected... the Political Stress Indicator, which in the past was strongly correlated with socio-political instability.

[T]here are important recurring patterns... throughout... human history over the past ten thousand years.

The main focus of SDT... is on the structural pressures undermining social resilience.

I claim that ... gives us a very good theoretical framework within which we can look at many different seemingly disparate trends in the United States... they suddenly start making sense... [D]eaths of despair ...I would argue that the opioid crisis is one of the manifestations of the immiseration, and in fact... go to Case and Deaton original book (project) on deaths of despair. They make this argument very eloquently. They give a lot of data, much better than I can do, so [the] opioid crisis is part of the bundle of reasons why immiserated population (people)... results in large swaths of [the] population who are falling... and many of them take the way out by either drugs and overdosing, or... suicide, or... alcoholism... or simply become careless and die in accidents... So this is clearly, and thanks to Anne Case and Angus Deaton for their excellent work, because here we can really see... The book is excellent. They talk about social immiseration, broken families and many other things. It really is a very coherent understanding of these problems.

...[A]s a result ...the new elites, let's call them the elite aspirants... their numbers... begin to be so large that there is not enough power positions in... politics or in economics [e.g., corporations]... That's fixed, and as the numbers of elite aspirants vying for these positions increase, then first... the result... is intraelite competition, and secondly... the numbers of frustrated elite aspirants who are denied access to these positions begins to explode.

We have analyzed CrisiDB because there's plenty of data on weather proxies. ...Weather, climate worsening seems to serve often as a trigger for crisis. But the key question is whether the societies have resilience... When populations are not immiserated and elites are not overproduced the social stability and resilience is very high, and societies adjust reasonably well to climate shocks. It's really when drivers for instability have been working for a while, that's when the climate can often serve as the trigger.

The focus [is] on only these four structural components... [E]ach component has a number of attributes that change dynamically in response to... [the] other... variables.

[N]one of the fundamental structural-demographic drivers have been reversed, so far. Thus, the American social system continues to be very vulnerable to additional "quakes".
