"You have to think dynamically... Im talking as a scientist about entering into a crisis, and then... societies have to somehow get out of it, so in Douglass North and his colleagues, for example, they look specifically at the Glorious Revolution... the exit from about 60 years of conflict, which started... in Scottish Wars 1639 and... ended in 1690s with the new arrangements. So... when societies exit from these crises... Sometimes, by the way, they dont exit, they essentially have political fragmentation. ...Think about the Roman Empire, which has fragmented, and there was no new Roman Empire. But frequently we do have reconstitution, ...England, for example, reconstituted itself. So think about it dynamically. You have to look at the path of the crisis, and then the path out of the crisis."
Peter Valentinovich Turchin is a Russian-American scientist who specializes in an area of study he and his colleagues developed called cliodynamics—mathematical modeling and statistical analysis of the dynamics of historical societies.
"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."
"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."
"Ortmans et al. Turchin P. 2010 conducted a similar structural-demographic study for the United Kingdom."
"Quantitative historical analysis reveals that complex human societies are affected by recurrent—and predictable—waves of political instability..."
"All these cycles look set to peak in the years around 2020."
"How resilient are our societies to internal and external shocks?"
