Mathematician Predicts Wave of Violence In 2020 397
ananyo writes "In a feature that recalls Asimov's Foundation series and 'psychohistory', Nature profiles mathematician Peter Turchin, who says he can see meaningful cycles in history. Worryingly, Turchin predicts a wave of violence in the United States in 2020. Quoting from the piece: 'To Peter Turchin, who studies population dynamics at the University of Connecticut in Storrs, the appearance of three peaks of political instability at roughly 50-year intervals is not a coincidence. For the past 15 years, Turchin has been taking the mathematical techniques that once allowed him to track predator-prey cycles in forest ecosystems, and applying them to human history. He has analyzed historical records on economic activity, demographic trends and outbursts of violence in the United States, and has come to the conclusion that a new wave of internal strife is already on its way. The peak should occur in about 2020, he says, and will probably be at least as high as the one in around 1970. 'I hope it won't be as bad as 1870,' he adds."
We recently discussed similar research into predicting violence in the short term.

While I agree that the sample size is small, there is certainly reason to think that if the political discourse continues as it is now, in eight years we could be in for that talk to start manifesting itself physically.

The guy isn't a mathematician, he's an ecologist. And I find it hard to believe that by 2020, social acceptance of domestic violence (say) rises again to mid-20th century levels. The reporter's suggestion that the precise moment in time of the Egyptian revolution was predictable is likely based on a misunderstanding of Turchin's work.
By the way, the field isn't as new as the article suggests. Steven Pinker's recent book, The Better Angels of Our Nature, collects quite a bit of quantitative research in this area, most of which does not support the existence of stable cycles.

Cliodynamics is viewed with deep scepticism by most academic historians, who tend to see history as a complex stew of chance, individual foibles and one-of-a-kind situations that no broad-brush 'science of history' will ever capture.....Most think that phenomena such as political instability should be understood by constructing detailed narratives of what actually happened — always looking for patterns and regularities, but never forgetting that each outbreak emerged from a particular time and place.

You have to be very careful with this kind of reasoning. It is close to saying, "Even though he doesn't have to evidence to back his claim, it fits my world view so I will use it to reinforce my current beliefs." This is the same kind of thinking that spreads conspiracy theories and group think, and it is an extraordinarily easy trap to fall into.
