Field Anomaly Relaxation
Also known as: FAR, Field Anomaly Relaxation Method, Rhyne FAR, Sectoral Morphological Scenario Method
Field anomaly relaxation (FAR) is a morphological scenario-construction method developed by Russell Rhyne in the 1970s for picturing how a whole societal or strategic system might evolve over time. It describes the situation through a small set of sectors — broad dimensions such as governance, technology, or values — each characterized by several alternative states, and arrays them as a morphological field whose combinations represent possible 'snapshots' of the system. Many of those combinations are internally inconsistent, so FAR 'relaxes' the field by removing anomalous configurations, leaving only coherent states of the world. Its distinctive final move is temporal: the surviving configurations are sequenced into plausible paths of change, producing scenarios as journeys from the present through a chain of consistent future states.
Key highlights
- Captures not only alternative future states but the plausible paths of change leading to them, adding a temporal dimension to morphological scenarios.
- Enforces internal consistency by relaxing anomalous configurations before any are linked into paths.
- Handles holistic, qualitative system descriptions that resist quantitative modeling, integrating many dimensions coherently.
- Keeps the assessment tractable through pairwise compatibility and transition judgments rather than evaluating whole configurations.

When to use it
Use field anomaly relaxation when you need holistic, long-range scenarios of how an entire system — a society, an industry, a policy environment — might evolve, and when the qualitative dimensions of that system interact too richly for quantitative modeling. It is well suited to strategic foresight exercises that must convey not just alternative end states but the plausible paths leading to them, and to facilitated expert groups able to characterize sectors, judge compatibility, and assess transitions. FAR is most appropriate at a broad, integrative level of analysis. It is less suitable for narrowly defined or quantifiable problems better served by trend or simulation methods, for situations where temporal sequencing adds little value over a static morphology, or where the number of sectors and states grows so large that compatibility and transition assessment become impractical.
Strengths & limitations
- Captures not only alternative future states but the plausible paths of change leading to them, adding a temporal dimension to morphological scenarios.
- Enforces internal consistency by relaxing anomalous configurations before any are linked into paths.
- Handles holistic, qualitative system descriptions that resist quantitative modeling, integrating many dimensions coherently.
- Keeps the assessment tractable through pairwise compatibility and transition judgments rather than evaluating whole configurations.
- Compatibility and transition judgments are subjective and rest on expert consensus, with no objective validation.
- Defining broad societal sectors and their states is difficult and strongly shapes the resulting scenarios.
- Pairwise compatibility cannot capture incompatibilities that emerge only among three or more states jointly.
- Sequencing configurations into paths adds a further layer of judgment whose plausibility is hard to verify.

Frequently asked
How does field anomaly relaxation differ from general morphological analysis?
Both build a morphological field of dimensions and states and eliminate internally inconsistent combinations through pairwise judgments. The defining difference is FAR's temporal step: after relaxing anomalous configurations, it sequences the surviving coherent configurations into plausible paths of change over time, so each scenario is a trajectory rather than a snapshot. General morphological analysis, as formalized by Ritchey, typically stops at the consistency-reduced field and explores it as a space of solutions. FAR thus adds an explicit dynamics — how one coherent state of the world could evolve into the next.
What does it mean to 'relax' an anomaly in FAR?
Relaxation is the elimination of configurations that contain anomalous, or mutually incompatible, pairs of sector-states. The analyst judges each pair of states from different sectors as compatible or anomalous, and any whole configuration including even one anomalous pair is removed from consideration. The term reflects the idea of letting the field settle into only those combinations that are internally tension-free. After relaxation, what remains is a gallery of coherent snapshots of the system, which then become the building blocks for sequencing into scenario paths.
Why does FAR sequence configurations into paths instead of presenting them separately?
Because a scenario, in FAR's view, is a story of change, not merely a description of an endpoint. Presenting coherent configurations in isolation would yield a set of possible futures but say nothing about how the system could move from today to any of them. By judging which configurations can plausibly succeed which others and chaining compatible ones forward from a present-like state, FAR produces trajectories that reveal turning points and routes of change. This path-oriented output is what makes the method especially useful for strategy, where the journey matters as much as the destination.
