Failing to forecast the Israeli-Palestinian crisis - The Washington Post - 0 views

Auguste Comte’s 19th century dream of a “social physics” that would “enquire into the present, in order to foresee the future, and to discover the means of improving it.” Historic events like the escalation of conflict and the achievement of peace, in the view of political forecasters, are just as predictable as more routine phenomena like election results or traffic patterns. They all obey the laws of political and social life, analogous to the laws of the natural world – or do they?

sophisticated vector-autoregression (VAR) models predicted routine events fairly accurately, but were far less accurate in predicting historic episodes like wars, uprisings and peace accords – the very events that political forecasters are most eager to anticipate.

Many of those historic moments involved “structural breaks,” a technical term that indicates shifts in the underlying parameters of the statistical model. These shocks to the system could not be extrapolated from prior data – they could only be identified as they occurred. All of this suggests that major historic events may not obey the same laws as the more routine events that precede them. Instead, major events can dissolve seemingly permanent laws of political and social life, initiating new patterns of interaction, for better or for worse.

When this sense of novelty becomes widespread, it can erase aspects of prior patterns of interaction, catching everybody by surprise. That is what happened during the Iranian Revolution. It happened again during the “Arab Spring” uprisings of 2011.

These momentous breaks from routine mark the limits of social-scientific knowledge. They stubbornly resist domestication in social-scientific models. What remains, I have proposed, is to study the experience of wildness. What does it feel like to live through such moments, to participate or avoid participation, to make history?
