SDT gives us understanding of the deep structural causes of socio-political instability and... tools for adopting... reforms and policy interventions… - Peter Turchin

You have to think dynamically... I'm 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 don't 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.

The next decade is likely to be a period of growing instability... which could undermine... scientific progress...

[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.
