The consumer society is so all-pervasive today that it is easy to assume it has always existed. Yet in reality it is one of the more recent innovatio… - Niall Ferguson

A defining feature of history is that there are many more black swans — not to mention what Didier Sornette calls “dragon kings,” events so large in scale that they lie beyond even a power-law distribution — than a normally distributed world would lead us to expect. All such events lie in the realm of uncertainty, not of calculable risk. Moreover, the world we have built has, over time, become an increasingly complex system prone to all kinds of random behavior, nonlinear relationships and “fat-tailed” distributions. A disaster such as a pandemic is not a single, discrete event. It invariably leads to other forms of disaster — economic, social and political. There can be, and often are, cascades or chain reactions of disaster. The more networked the world becomes, the more we see this.

European centrists are deeply confused about immigration. Many, especially on the centre-left, want to have both open borders and welfare states. But the evidence suggests that it is hard to be Denmark with a multicultural society. The lack of social solidarity makes high levels of taxation and redistribution unsustainable.

I disbelieve in both cycles of history and ends of history. History is the interaction of many complex systems. There are certain long-run processes (notably exponential gains in productivity through the development of technology and the “suprasecular” decline of nominal and real interest rates as a result of capital accumulation) punctuated by, well, one disaster after another. These disasters are either randomly distributed or follow a power law (i.e. there are lots of little earthquakes, pandemics or wars, but a few cataclysmic ones). At unpredictable intervals, the global system is tipped into a major transition by a disturbance that can be quite small, if not quite as small as Edward Lorenz’s famous butterfly in the Amazon setting off a tornado in Texas. Russia’s war in Ukraine — destructive certainly, but still a relatively small conflict by 20th-century standards — can be enough to trigger a “conflict avalanche.”
