The Five-Factor Framework
Diamond's comparative taxonomy of civilizational collapse — environmental damage, climate change, hostile neighbors, trade disruption, and societal response — in which the fifth factor carries the entire moral weight.
The five-factor framework is Jared Diamond's structural instrument for comparing civilizational outcomes across radically different environments, centuries, and cultures. Developed across decades of fieldwork and refined in Collapse, the framework identifies four categories of challenge a society may face — self-inflicted environmental damage, external climate change, hostile neighbors, and the loss of friendly trading partners — and one category of response: what the society itself does about the first four. Diamond's central finding, supported by dozens of case studies, is that severity of challenge does not predict collapse. Quality of response does. The framework locates agency precisely where agency exists, and produces a comparative method in which the variable of interest is always the fifth factor.

The framework emerged from Diamond's frustration with explanations that treated civilizational collapse as either inevitable (driven by forces beyond human control) or mysterious (the product of unknown cultural failures). Neither was analytically satisfying. The Norse Greenlanders and the Inuit
