In 2010, the scientific journal Nature published a collection of opinions looking ahead 10 years, i.e., where we are right now.
Nature then published a short response from zoologist Peter Turchin in its February 2010 issue.
Quantitative historical analysis reveals that complex human societies are affected by recurrent — and predictable — waves of political instability (P. Turchin and S. A. Nefedov Secular Cycles Princeton Univ. Press; 2009). In the United States, we have stagnating or declining real wages, a growing gap between rich and poor, overproduction of young graduates with advanced degrees, and exploding public debt. These seemingly disparate social indicators are actually related to each other dynamically. They all experienced turning points during the 1970s. Historically, such developments have served as leading indicators of looming political instability.
Again, that was from 2010. Right on schedule, we are experiencing the “instability spike” Turchin says tends to come along every 50 years.
