In Paul Nuttall, Ukip’s hypocrisy is finally being revealed by Zoe Williams (The Guardian)
[Ukip chief donor Arron] Banks is a distinctly British example of what the biologist and anthropologist Peter Turchin calls “elite overproduction”. Turchin is a pioneer of cliodynamics, a discipline that examines history as a science, modelling trends mathematically according to a series of measures – inequality and population growth being the two most obvious.
APOCALYPSE WARNING: Billionaires buy up land in NEW ZEALAND as they look for safe haven by Sean Martin (Express)
The news comes just weeks after a scientist ran calculations to predict that Western society could collapse by 2020.
Peter Turchin, a professor of ecology and mathematics at the University of Connecticut, has been studying history as if it were a science and, by analysing past societies, has concluded the current societal norms are nearing their end.

Mathematician predicts the next decade will be awful. by Michael Kaplan (New York Post)
Call it the mathematics of misery. A professor from the University of Connecticut claims that his numerical calculations predict years of turmoil and unrest for the world. A pioneer in a new field of math known as “cliodynamics,” Russia-born Peter Turchin — who’s in the university’s departments of ecology and evolutionary biology, anthropology and mathematics — told the Daily Mail that his calculations “treat history as just another science.” According to Turchin’s homepage, cliodynamics “uses the tools of complexity science and cultural evolution to study the dynamics of historical empires and modern nation-states.”
Society could COLLAPSE within a decade, ‘mathematical historian’ predicts. by Jasper Hamill (The Sun)
Peter Turchin, a professor at the University of Connecticut’s department of ecology and evolutionary biology, said the next decade would be marked by political turmoil and social unrest. The academic is the world’s leading advocate of a discipline called cliodynamics, which believes historical events such as the growth and collapse of empires or religions follow clearly definable patterns.

Is civilisation heading for a COLLAPSE? Mathmatical historian predicts political turmoil will peak in the 2020s by Abigail Beall (Daily Mail)
The rise and fall of civilisations can be predicted by a simple equation, and our civilisation is in for a fall some time soon. This is according to Peter Turchin, from the University of Connecticut, who says mathematics can explain human behaviour far more accurately than you might think.
Society to COLLAPSE in 2020s claims expert historian by George Martin (Daily Star)

The database that is rewriting history to predict the future by Laura Spinney (New Scientist)
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.
Breaking point: America approaching a period of disintegration, argues anthropologist Peter Turchin by Paul Rosenberg (Salon)
As the 2016 campaign reaches fever pitch, the more heat there is and the less light is shed. Which is why evolutionary anthropologist Peter Turchin’s new book comes as such a breath of fresh air. “Ages of Discord: A Structural-Demographic Analysis of American History” is not about this year’s presidential election, per se, but it’s a quantum leap forward in illuminating the disintegrative trends that America has experienced over the last several decades that are currently driving our politics.

In the Science of Civilizations, Brexit Is the European Union’s Reckoning by Nick Stockton (Wired.com)
Turchin describes historical empires as large-scale, multi-ethnic conglomerations—ones that wouldn’t come together except under a mighty ruling class. And across those different empires, Turchin and his anthropology colleagues look for commonalities. How do policies developed by the ruling class, for example, affect the general population’s ability to weather recession or disease? Then they develop mathematical models that strive to explain how civilizations rise and fall.
Mass Karma by Robert Koehler (Huffington Post)
The murders are not personal. The killer is employing what’s known as the “principle of social substitutability” — substituting a particular group of people for a general wrong.
“The rampage shooters see themselves as moralistic punishers striking against deep injustice,” Peter Turchin explains in his essay “Canaries in a Coalmine.” “. . . it is usually a group, an organization, an institution, or the whole society that are held responsible by the killer.
“On the battlefield,” he wrote, “you are supposed to try to kill a person whom you’ve never met before. You are not trying to kill this particular person, you are shooting because he is wearing the enemy uniform. . . . Enemy soldiers are socially substitutable.”

War, Peace and Inequality IAST Connect
Peter Turchin is an evolutionary anthropologist at the University of Connecticut who wants to revolutionize the study of the past. An expert on dynamical systems analysis, the Russian-American now aspires to paint big-picture history using big data, devising mathematical models to test social science theories empirically. On an extended visit to Toulouse, he met up with Mohamed Saleh, assistant professor at TSE and the IAST where he also directs the history program, who combines novel data sources, economic theory and empirical methods to examine Middle Eastern economic history. Their intriguing discussion of the evolution of inequality, war and human cooperation suggests we have much to gain from the debate on whether history can be treated as a ‘science’.
What Ancient History Has to Say About Near Future Doom by Ned Resnikoff (IB Times)
University of Connecticut professor Peter Turchin has described that mismatch as a problem of “elite overproduction,” the process by which a growing number of elites got thrown into competition over a proportionally shrinking number of trophies. He says that phenomenon didn’t just help bring down the Roman Republic; it also contributed to the onset of the American Civil War, along with countless other historical calamities.
Has ritual human sacrifice shaped societies and class systems? by Colin Barras (New Scientist)
Peter Turchin at the University of Connecticut thinks the new analysis misses a broader point, because the Austronesian cultures are all relatively small, lacking the complexities of larger societies around the world. “Human sacrifice is actually a maladaptive cultural trait,” he says.
Turchin is a member of a team analysing the global history of social and political organisation. Their preliminary results show that extreme inequality – characterised by traits including human sacrifice and slavery – is a stage that cultures quickly grow out of as they develop.
This is because extreme inequality leaves societies weaker and more likely to be destroyed in wars than societies with more egalitarian structures.
“Its all relative: these ‘egalitarian’ societies still have nobles and lords,” says Turchin. “But they have dispensed with the most extreme forms of inequality including human sacrifice.”

The principle of top down hierarchy seems extraordinarily resilient in human societies. But why have we come to organise ourselves this way? Is it to be more efficient and effective? Or, is it because some people will always be driven by instinctive greed and desire for power?

Le printemps arabe, une révolution pour l’élite? par Dominique Baillard/RFI
En fait personne n’a été capable de prévoir ces révolutions. Il est impossible de repérer l’étincelle qui va faire exploser la cocotte. En revanche, on peut mesurer la pression dans la marmite, et voir si elle est corrélée à un certain nombre de facteurs socio-économiques. C’est ce que le chercheur américain Peter Turchin a fait en construisant son modèle dans le pays qu’il connaissait le mieux, les Etats-Unis.

“We are, right now, climbing that inequality curve and all the signs are there: low taxes on the rich and low wages for workers. And there’s another warning sign: a rising number of wealthy, educated elites competing for a fixed number of high political offices. The stiffer the competition, the more ruthless they become.”

The maths that saw the US shutdown coming (The New Scientist)
“Turchin finds that a simple mathematical model, combining economic output per person, the balance of labour demand and supply, and changes in attitudes towards redistributing wealth – the minimum wage level is one proxy for this – generates a curve that exactly matches the change in real wages since 1930, including complex rises and falls since 1980. Such close agreement between model and reality is exceptional in social sciences, says Turchin, and shows that all three factors control the rise of inequality, as predicted.”

Corriere della Sera: Il matematico che vuole prevedere il futuro
The mathematician who wants to predict the future. Peter Turchin’s wager: extract data from the past and sketch the evolution of history. He invented a new discipline: cliodynamics, inspired by the books of Asimov.
Wired: Mathematicians predict the future with data from the past
In Isaac Asimov’s classic science fiction saga Foundation, mathematics professor Hari Seldon predicts the future using what he calls psychohistory. Drawing on mathematical models that describe what happened in the past, he anticipates what will happen next, including the fall of the Galactic Empire. That may seem like fanciful stuff. But Peter Turchin is turning himself into a real-life Hari Seldon — and he’s not alone.
Quantitative History Makes a Comeback: Historians Argue for a Scientific Study of the Past by Marc Parry in the Chronicle of Higer Education
Numbers illuminate the shape of history. That’s a core belief of the Stanford archaeologist and historian Ian Morris, and his book Why the West Rules—for Now puts it into practice by quantifying the development of different societies. But he’s hardly the only one. A growing crop of scholars share Morris’s science-steeped, big-picture approach to the past. And while his book relies on simple mathematics, others go further. They aspire to capture history in equations. And they want to use math to predict how the future might play out, given different assumptions about factors like population growth or climate change. “There are people much weirder than me out there,” says Morris.
Among the most prominent of these is Peter Turchin, a professor of ecology and evolutionary biology at the University of Connecticut.

BBC: Can you predict a revolution? (my interview)
We are eight years away from revolution: that is according to the science of cliodynamics. This is the analysis of rise and fall of empires using mathematical tools to come up with laws of history. This theoretical approach has been pioneered by Professor Peter Turchin of the University of Connecticut. He told the Today programme’s business presenter, Simon Jack, what generally preceded revolution or war. “It’s the elites that cause civil wars” he explained. “When the elites become disgruntled and start infighting between themselves… that’s what causes the problems.”
NewScientist: Calculated violence: Numbers that predict revolutions
PETER TURCHIN thinks he can see the future. Unlike the fortune teller you might find at a seaside carnival, he needs no crystal ball. Instead, the tools of his trade are mathematics and testable theories. Armed with these, his goal is nothing less than to revolutionise the study of history, turning it from a mass of anecdotes into a rigorous, predictive science.
Vice.com: 2012 Is Bullshit; 2020 Is When We’ll Really Be in Trouble
Peter Turchin is a Russian-American scientist who specializes in population biology and devises theories, backed by cumulative scientific evidence, that, in their essence, predict the future by tracking “temporally varying processes and the search for causal mechanisms” throughout history. He calls his field of study “cliodynamics,” after Clio, the Greek Muse of history, and it’s been getting a lot of attention lately following an article about his research in the science journal Nature.
Circa 1870, the North fought the South in the Civil War. Half a century later, around 1920, worker unrest, racial tensions and anti-Communist sentiment caused another nationwide upsurge of violence. Then, 50 years later, the Vietnam War and Civil Rights Movement triggered a third peak in violent political, social and racial conflict. Fifty years after that will be 2020. If history continues to repeat itself, we can expect a violent upheaval in the United States in a few years.

News Feature in Nature on Human Cycles: History as Science by Laura Spinney
“Turchin’s approach — which he calls cliodynamics after Clio, the ancient Greek muse of history — is part of a groundswell of efforts to apply scientific methods to history by identifying and modelling the broad social forces that Turchin and his colleagues say shape all human societies. It is an attempt to show that “history is not ‘just one damn thing after another’”, says Turchin, paraphrasing a saying often attributed to the late British historian Arnold Toynbee.”

Our PNAS Article on Roman Censuses and Coin Hoards in the Popular Press
Several major world newspapers discussed our results: New York Times (USA), Spiegel (Germany), Standaard (Belgium), and Folha de S. Paulo (Brazil). Other media that discussed it include N-TV (the German TV channel for financial news), ORF (Austrian Public TV), and Echo Moskvy (a Russian radio station). The article in Science includes a rejoinder from a proponent of the high count hypothesis (which we reject in our paper). The story was featured in the science sections of Yahoo, Yahoo-UK, Lenta and Infox (Russia), and EuropaPress (Spain). Other web-based sources that covered the story are Wired,EurekAlert, and NSF News (the latter includes a video interview).
The story also appeared in a variety of popular science magazines and web sites. The ones I know about are: FirstScience, WorldScience, ScienceDaily,e!ScienceNews, Wissenschaft-Online, Epoc, Huscarl, Gallileo, Elementy, and MultKor.
Last, but not least, is our own UConn Today, which perhaps lacks the wide readership of New York Times or Spiegel, but was the only publication that managed not to garble any aspects of the story.

The future of history: Why it needs to become a science
“For much of human history we have plenty of facts. The job of historians is to select and arrange those facts to support a range of subjective interpretations. Peter Turchin thinks that at that rate, we are doomed to repeat our mistakes. Instead, he says, we need unifying theories. We should use the data to construct general explanations, and test them on all the data, not a subset chosen to make a point. To learn from history, first we must make it science.”

A review of War and Peace and War in The New Scientist by Mark Buchanan
“Are there ‘laws of history’, patterns or regularities that would let us make predictions? Karl Marx thought he saw a steady progression in history, leading inevitably to a future of world government by the workers. British historian Arnold Toynbee saw cyclic patterns in the rise and fall of civilisations. But most historians today think that Marx and Toynbee were deluded, and that the pursuit of historical laws is, in general, a fool’s errand. Refreshingly, Peter Turchin doesn’t agree.”
