You misunderstood not only the study but its purpose. It was not meant to be a crystal ball and predict events and the time when they will take place. Any one with a bit of common sense and a basic knowledge of history can conclude that civilizations or segments of, and social orders came into existence and if they were viable they rose, reached an apex and then declined. What was in question is the existence of common causes considering the various time frames in history and their specific socio-economic conditions. The mathematical modeling used in this study found the common causes that transcend the various times and particular conditions and concluded that under current trends the collapse of the present system is also possible to a high degree.Their conclusion itself reads much like a social theory paper, and thus makes me question if that was the conclusion they originally started with.
The article even says that "collapse theories are considered fringe" and presents two other pieces of work that use the exact same methodology with much much less drastic conclusions.
It's right in the OP.
