We’re on the verge of breakdown: a data scientist’s take on Trump and Biden by Edward Helmore (The Guardian)

Peter Turchin is not the first entomologist to cross over to human behaviour: during a lecture in 1975, famed biologist E.O. Wilson had a pitcher of water tipped on him for extrapolating the study of ant social structures to our own. It’s a reaction that Turchin, an expert-on-pine-beetles-turned-data-scientist and modeller, has yet to experience. But his studies at the University of Connecticut into how human societies evolve have lately gained wider currency; in particular, an analysis that interprets worsening social unrest in the 2020s as an intra-elite battle for wealth and status.

Peter Turchin: The Magnetism of Mathematical History by Enza Jonas-Giugni (Science Survey)

The chaos of 2020 launched Peter Turchin from relative obscurity into the spotlight. In 2010, Turchin made the startling prediction that “the next decade is likely to be a period of growing instability in the United States and western Europe,” a statement which he supported with statistical data analysis of past historical trends.

The astonishing accuracy of his foresight, substantiated by the tumultuous socio-political events of this past year, have given rise to his sudden notoriety. Turchin’s mathematical history — a field coined “cliodynamics” — has now ascended into the realm of academic renown, captivating audiences with its ability to anticipate the future.

How did the craziness of 2020 get predicted back in 2012? (Scott Radley Show radio interview)

Approximately 8 years ago, there was a projection made that in 2020 there would be some form of upheaval that we would go through. How could a theory like this be made so long ago and if it could predict what’s happening now, what’s coming next? Guest: Dr. Dan Hoyer, Senior Project Manager, Seshat: Global History Databank

America, We Have a Problem by Thomas B. Edsall (New York Times)

Turchin, in a 2017 book, “Ages of Discord: A Structural-Demographic Analysis of American History,” graphed political stress in this country, showing that from 1970 to 2012 it shot up sharply, increasing fortyfold. In the eight years since then, stress has continued to surge, Goldstone wrote, “as income inequality, political polarization and state debt have all risen further.”

The real class war is within the rich by Janan Ganesh (Financial Times)

Peter Turchin, the academic of the moment, does more than that. He quantifies, cross-refers with other variables and arrives at a theory. Of all the reasons adduced for the political strife of our time, few are as novel as his stress on “elite overproduction”. Graduates have multiplied faster than the room at the top, he says, with the “lawyer glut” being especially gross. The result is a stock of nearly-men and women whose relationship with their own class sours from peripheral membership to vicious resentment. If this coincides with a bad time for the general standard of living, there is an alliance to be formed between these snubbed insiders and the more legitimately aggrieved masses.

The Next Decade Could Be Even Worse by Graeme Wood (The Atlantic)

To seed the journal’s research, Turchin masterminded a digital archive of historical and archaeological data. The coding of its records requires finesse, he told me, because (for example) the method of determining the size of the elite-aspirant class of medieval France might differ from the measure of the same class in the present-day United States. (For medieval France, a proxy is the membership in its noble class, which became glutted with second and third sons who had no castles or manors to rule over. One American proxy, Turchin says, is the number of lawyers.) But once the data are entered, after vetting by Turchin and specialists in the historical period under review, they offer quick and powerful suggestions about historical phenomena.

Information technology played key role in growth of ancient civilizations by Will Ferguson (Science Daily)

For their study, Kohler and colleagues at the Santa Fe Institute set out to discover more about the role information technology played in the growth of human societies from the Neolithic to the last millennium.

They dug into what’s called the Seshat Global History Databank, a massive assembly of historical and archaeological information spanning more than 400 societies, six continents and 10,000 years of human history.

The databank enabled the researchers to quantitatively analyze things like how large were civilizations when they developed writing, systems of coinage and other innovations in information processing and what were the effects of these advances on the growth of the overall state.

When did societies become modern? ‘Big history’ dashes popular idea of Axial Age by Laura Spinney (Nature)

It’s an idea that has been influential for more than 200 years: around the middle of the first millennium BC, humanity passed through a psychological watershed and became modern. This ‘Axial Age’ transformed an archaic world of divine rulers, slavery and human sacrifice into a more enlightened era that valued social justice, family values and the rule of law. The appeal of the general concept is such that some have claimed humanity is now experiencing a second Axial Age driven by rapid population growth and technological change. Yet according to the largest ever cross-cultural survey of historical and archaeological data, the first of these ages never happened — or at least unfolded differently from the originally proposed narrative.

La modélisation de l’histoire prédit un cycle de crises dès 2020 by Odile Romelot (Slate.fr)

Collecter, analyser et interpréter des données historiques est ce qui anime Peter Turchin, un biologiste qui se servait autrefois des mathématiques pour matérialiser les interactions entre proies et prédateurs, rapporte Laura Spinney dans un article du Guardian. En 2010, Turchin estimait que l’instabilité politique croissante atteindrait son paroxysme en 2020 aux États-Unis et en Europe. L’humanité traversant des phases de croissance et de déclin, 2020 signerait le début d’un cycle de crises. L’argument n’est pas nouveau, mais il s’appuie sur une analyse précise de différents facteurs tels que l’augmentation des inégalités et de la dette publique. Et surtout, il a le mérite d’avoir semble-t-il visé juste, alors que Trump risque d’être destitué et que le Royaume-Uni est englué dans un Brexit sans fin.

Cliodynamics: can we use history to forecast the future? (The Week)

Could gathering data from the past help us prevent a future disaster? An evolutionary anthropologist at the University of Connecticut has dedicated his career to answering this question.

Professor Peter Turchin founded a new field of academic study called cliodynamics in 2003, and then set up a research consortium eight years later to build a huge historical database called Seshat in a bid to uncover major patterns in world history.

How belief in punitive gods may have helped large societies cooperate by Chelsea Whyte (New Scientist)

This may mean that belief in a punitive god could make people more willing to share resources across a large society. “Religion created a sense of us versus them and as societies grew into empires that must have been a very important factor in keeping them cohesive,” says Peter Turchin at the University of Connecticut. While the experiments show that punitive gods may influence human cooperation, it may also work the other way around. Turchin says his research into historical societies shows that belief in punitive gods tends to arise after the appearance of large-scale societies. Today, punitive gods play no role in some highly cooperative societies, he says. “This is because other social technologies play the same role, such as very persuasive bureaucratic control or social control by neighbours.”

Our Unfinished Agenda (What I Have Learned) by Timothy A. Kohler (The SAA Archaeological Record)

My second example comes from a recent analysis of a large historical and archaeological dataset called “Seshat: Global History Databank” (http://seshatdatabank.info) amassed and analyzed for 30 regions of the world spanning the last 10,000 years by Peter Turchin and numerous colleagues (2018). These researchers coded data on 51 variables for each of these regions (selected to be relatively independent of each other) by 100-year time slices. They consider these variables to fall within nine large clusters that they call “complexity characteristics.”

Did Human Sacrifice Help People Form Complex Societies? by Laura Spinney (The Atlantic)

The results coming out of Seshat—which have yet to be published—suggest that social control may not be the whole story, however. No society in Pulotu comprises more than a million people, while Seshat includes “mega-empires” whose subjects numbered in the tens of millions. Seshat’s founders therefore argue that it tracks social complexity closer to modern levels, and they find that, beyond around 100,000 people, human sacrifice becomes a destabilizing force. “Our suggestion is that this particularly pernicious form of inequality isn’t sustainable as societies get more complex,” says Whitehouse. “It disappears once they pass certain thresholds, because they cannot survive with that level of injustice.”

Human Sacrifice Was the Key to Social Evolution, New Study Says by Andrew Lasane (Outer Places)

University of Oxford anthropologist Harvey Whitehouse and his team have developed a separate database (Seshat) that approaches the subject from a different angle.

Whitehouse says that it is better to cast a wider net and test theories against the data, instead of focusing on data that may already support a theory. Seshat includes data from 400 different historical societies and goes back 10,000 years.

Trinity data behind new research which suggests common path governed evolution of societies (Irish Examiner)

Scientific historians, using data collected via a platform developed at Trinity College Dublin, have today published a report suggesting that a single dimension of ‘social complexity’ measures the development of around 400 past societies that existed over the last 10,000 years.

The data used in this project come from the Seshat: Global History Databank, directed by Peter Turchin, Harvey Whitehouse, Pieter Francois, Thomas Currie, and Kevin Feeney.

The Seshat project gathers information from past societies in order to rigorously test different hypotheses about the rise and fall of large-scale societies across the globe, and over the course of human history. Seshat seeks to bring together in one place the largest collection of data on our shared human past that has ever been assembled.

Seshat, vers un « massacre des théories » historiques? by Rémi Sussan (Internet Actu)

“Selon le New Scientist, Seshat est une réponse possible à l’accumulation des data qui a transformé la profession des historiens, et pas forcément dans le sens de la facilité. Selon le magazine, cette brusque augmentation des informations a amené la plupart des spécialistes du domaine à travailler isolément : qui sur la démographie, qui sur les institutions, qui sur la religion, etc. Tant et si bien qu’il devient très difficile de percevoir les schémas globaux. De plus si certains patterns historiques sont assez évidents, d’autres sont bien plus masqués et ne peuvent se révéler que lorsqu’on associe plusieurs sources.

L’un des premiers buts de Seshat sera de vérifier des hypothèses, et éliminer les moins vraisemblables. Son objectif, pour employer l’expression de Turchin, sera de procéder à un « massacre des théories », autrement dit à une large série de réfutations d’hypothèses sur les différents aspects des civilisations.”

It is, essentially, a giant machine for turning hundreds of thousands of “facts”- where the ancient Britons polythestic? Did the Mayans practise crop rotation?- into models in which researchers can compute how important different factors were in historical events.

Seshat is a vast and growing database of historical and archaeological knowledge that can be explored using scientific techniques. That makes it a powerful tool for testing and ultimately discarding hypotheses. “A cemetery for theories,” is how Seshat co-founder Peter Turchin at the University of Connecticut in Storrs describes it. By making history more evidence-based, he and his colleagues hope it will become more relevant.
