Peter Turchin is a Russian-American scientist who specializes in population biology and devises theories, backed by cumulative scientific evidence, that, in their essence, predict the future by tracking “temporally varying processes and the search for causal mechanisms” throughout history. He calls his field of study “cliodynamics,” after Clio, the Greek Muse of history, and it’s been getting a lot of attention lately following an article about his research in the science journal Nature.
