Polycrisis Resilience: A General Definition and the H Heuristics Framework

The flagship statement of the concept: a general definition usable across disciplines, six capacities from prevention to transformation, and a development-oriented framework that applies four drivers to five systems through a five-stage cycle of continuous improvement.

The defining risks of this century do not arrive one at a time. Climate change, environmental degradation, economic instability, geopolitical conflict, demographic change, public health threats, technological disruption and fragile infrastructure now act on one another, so that the harm entangled crises cause together exceeds the sum of their separate effects. This flagship report sets out a concept for that condition, Polycrisis Resilience, and a framework for building it, the H Heuristics Polycrisis Resilience Framework, which it presents as concepts developed by Hunter Hughes, Founder of H Heuristics. It defines Polycrisis Resilience as the capacity of individuals, communities, institutions, economies, societies and interconnected systems to anticipate, withstand, adapt to, recover from and reduce their vulnerability to multiple interacting crises.

Polycrisis Resilience

Existing resilience, risk-reduction and adaptation work is organised hazard by hazard, while the risk arrives through the connections. A proposed framework defines the capacity to respond to the interactions themselves, and a six-question test to screen any action against it.

The Architecture of Centrality

Galaxies, cells, airline networks and states all concentrate around a few dominant nodes. Nine original calculations show five processes build these centers, that they are efficient but fragile, and that the systems which last keep a center without depending on only one.

The Global Variant Matrix

Do strong look-alikes turn up on every continent, and do they form one connected pattern? A proposed framework, a research programme to test it, and firm boundaries against any reading of it as human types.
