History Does Not Crawl, It Jumps
Taleb argues that consequential historical changes often arrive abruptly, while explanations assembled afterward can make them seem predictable. His recollections of the Lebanese war illustrate the gap between living through uncertainty and telling a coherent story about it later.
THE IDEA
History Does Not Crawl, It Jumps
Later, upon replaying the wartime events in my memory as I formulated my ideas on the perception of random events, I developed the governing impression that our minds are wonderful explanation machines, capable of making sense out of almost anything, capable of mounting explanations for all manner of phenomena, and generally incapable of accepting the idea of unpredictability. These events were unexplainable, but intelligent people thought they were capable of providing convincing explanations for them—after the fact. Furthermore, the more intelligent the person, the better sounding the explanation. What’s more worrisome is that all these beliefs and accounts appeared to be logically coherent and devoid of inconsistencies.
So I left the place called Lebanon as a teenager, but, since a large number of my relatives and friends remained there, I kept coming back to visit, especially during the hostilities. The war was not continuous: there were periods of fighting interrupted by “permanent” solutions. I felt closer to my roots during times of trouble and experienced the urge to come back and show support to those left behind who were often demoralized by the departures—and envious of the fair-weather friends who could seek economic and personal safety only to return for vacations during these occasional lulls in the conflict. I was unable to work or read when I was outside Lebanon while people were dying, but, paradoxically, I was less concerned by the events and able to pursue my intellectual interests guilt-free when I was inside Lebanon. Interestingly, people partied quite heavily during the war and developed an even bigger taste for luxuries, making the visits quite attractive in spite of the fighting.
There were a few difficult questions. How could one have predicted that people who seemed a model of tolerance could become the purest of barbarians overnight? Why was the change so abrupt? I initially thought that perhaps the Lebanese war was truly not possible to predict, unlike other conflicts, and that the Levantines were too complicated a race to figure out. Later I slowly realized, as I started to consider all the big events in history, that their irregularity was not a local property.
The Levant has been something of a mass producer of consequential events nobody saw coming. Who predicted the rise of Christianity as a dominant religion in the Mediterranean basin, and later in the Western world? The Roman chroniclers of that period did not even take note of the new religion—historians of Christianity are baffled by the absence of contemporary mentions. Apparently, few of the big guns took the ideas of a seemingly heretical Jew seriously enough to think that he would leave traces for posterity. The scarcity of surviving early accounts is part of his argument, though scarcity alone cannot establish that no one anticipated Christianity’s spread. How about the competing religion that emerged seven centuries later; who forecast that a collection of horsemen would spread their empire and Islamic law from the Indian subcontinent to Spain in just a few years? Even more than the rise of Christianity, it was the spread of Islam (the third edition, so to speak) that carried full unpredictability; many historians looking at the record have been taken aback by the swiftness of the change. Georges Duby, for one, expressed his amazement about how quickly close to ten centuries of Levantine Hellenism were blotted out “with a strike of a sword.” A later holder of the same history chair at the Collège de France, Paul Veyne, aptly talked about religions spreading “like bestsellers”—a comparison that indicates unpredictability. These kinds of discontinuities in the chronology of events did not make the historian’s profession too easy: the studious examination of the past in the greatest of detail does not teach you much about the mind of History; it only gives you the illusion of understanding it.
History and societies do not crawl. They make jumps. They go from fracture to fracture, with a few vibrations in between. Yet we (and historians) like to believe in the predictable, small incremental progression.
It struck me, a belief that has never left me since, that we are just a great machine for looking backward, and that humans are great at self-delusion. Every year that goes by increases my belief in this distortion.
When to use it
Test whether a financial or geopolitical plan can withstand an abrupt change that its forecast does not anticipate.
Challenging overconfident historical analyses or forecasts that assume continuity.
Understanding personal or organizational change: recognizing that breakthroughs often come suddenly, not gradually.
Improving decision-making by accounting for the limits of prediction and the role of randomness.
FROM THEORY TO EVERYDAY LIFE
In practice
The Rise of Christianity
Taleb uses Christianity’s rise to question whether contemporary observers could foresee which movements would become consequential. His broader point concerns hindsight: a later coherent account does not establish that an outcome was predictable.
The Spread of Islam
Taleb invokes the expansion of Islamic rule across a large region as an example of rapid historical change. He cites Duby’s and Veyne’s descriptions to emphasize the contrast between an orderly chronology and the uncertainty faced by people living through it.
The Lebanese War
People who seemed models of tolerance became barbarians overnight, and the war was filled with unpredictable fractures rather than continuous progress.
A MOMENT TO REFLECT
Put it to work.
Think of a major historical event that seemed to come out of nowhere. How do people explain it after the fact, and how might those explanations be just narratives?
In what areas of your own life do you assume gradual progress when the reality might be jumps? How can you prepare for that uncertainty?
Consider a decision you made based on past trends. How might the 'history jumps' concept expose the fragility of that reasoning?
