The Proposition

Before we intervene in a situation, we have already made a consequential decision: we have decided what kind of thing the situation is. A housing crisis can be understood as a shortage, a market failure, a distribution problem, a legal regime, a political settlement, a history of dispossession, an infrastructure problem, an ecology, a coordination failure, a narrative, or a struggle over power.

None of these descriptions is neutral. Each makes certain causes vivid and others difficult to see. Each produces characteristic questions. Each makes some interventions appear obvious, others absurd, and still others literally unimaginable. This is ontology at work.

Ontology sounds like a word philosophers invented to keep everyone else out of the room. Its practical meaning is much more dangerous: what do we believe reality is made of, and how do we believe change happens within it? For Intervention Design Thinking, ontology is not ornamental philosophy. It is part of the intervention apparatus.

Ontology → Perception → Causality → Force → Intervention → Consequence. Change the ontology and you change the intervention repertoire. The capable interventionist therefore learns not one correct way of seeing a system, but how to move deliberately among several.

I. Seven Armories

These are not seven competing theories of reality. They are seven families of lenses, each carrying a different repertoire of force.

II. The Kata

The armories are useless if they remain on the wall. The practice is learning to move between them.

• 1

  Witness

  Describe the situation before prescribing anything. What is happening, to whom, where, for how long? Resist explanation temporarily.

• 2

  Choose three lenses

  Choose lenses that disagree with one another. If Structure seems obvious, try Meaning. If Power seems obvious, try Cybernetics. Difference is productive.

• 3

  Reconstruct reality

  For each lens: if this situation is fundamentally a ________, then what is causing what we observe? Actually change the causal model, not merely the vocabulary.

• 4

  Generate native interventions

  Only propose interventions that make sense within that ontology — a legal ontology might produce a statutory duty, an ecological ontology a viable alternative niche, a power ontology an organized constituency.

• 5

  Find convergence

  Lay the interventions over one another. Some will compete, some will be irrelevant. Occasionally three entirely different ontologies will point toward the same place. Circle that place — you may have found leverage.

• 6

  Compose force

  Ask what combination is required: persuasion, coordination, capital, law, refusal, public legitimacy, technical architecture, collective action. Design the composition.

• 7

  Make the wager

  Write the causal claim explicitly: we wager that if we ________, then ________ will change because ________. Then add the line usually omitted: the ontology beneath this wager is ________.

III. The Armory Is Not the Arsenal

An ontology is not a tactic. A tactic is something you do. A strategy coordinates actions toward an objective. An ontology determines what kinds of causes, objectives, strategies and tactics you are capable of seeing.

The tradition of strategic nonviolence has already produced formidable arsenals — Gene Sharp’s methods of protest and noncooperation, movement strategists’ power mapping, pillars of support, spectra of allies, points of intervention, escalation and dilemma actions. Intervention Design should learn these repertoires rather than reinvent them. Its distinctive contribution is to ask one step earlier: why did this particular battlefield become visible to us in the first place?

IV. From Seeing to Force

Once several ontologies reveal possible interventions, another question begins — not what should we design, but what form of force could actually alter this arrangement? Force does not mean violence. A law applies force. A union applies force. A protocol applies force. A price applies force. A boycott applies force by withdrawing economic cooperation. An interoperable protocol can apply extraordinary force by making an incumbent’s permission irrelevant.

A field manual for intervention therefore distinguishes at least: persuasive, relational, economic, institutional, legal, political, technical, cultural, cooperative, and withdrawal force. The interventionist asks not which force sounds most admirable, but which forces the causal structure will actually answer to.

V. Power With / Power To / Power Under / Power Over

The field manual also asks what kind of power the intervention creates. Power over — the capacity to constrain another actor — is sometimes necessary and always deserving scrutiny. Power to is the capacity to accomplish something previously impossible; infrastructure, knowledge, rights and resources often create it. Power with is capacity produced through coordination — movements, unions, coalitions, commons, mutual aid. Power within is the capacity for agency, confidence, discernment and refusal, often invisible in conventional power maps.

Power under is the latent leverage possessed by actors on whom a dominant arrangement depends. Workers can stop working. Customers can stop buying. Citizens can withdraw legitimacy. Developers can fork software. Communities can refuse cooperation. The apparently powerless may be holding up the building.

VI. The Interventionist’s Test

Before committing substantial resources, ask: what do we believe this situation is made of? Which ontology produced that belief? What does it illuminate, and what does it systematically hide? Which competing ontology produces the most uncomfortable reinterpretation? Where does power actually reside, and upon whose cooperation does it depend? What form of force can reach it, and at what point should it be applied? What happens after it succeeds?

And finally: what new arrangement of power will our intervention leave behind? Because winning the intervention while reproducing the underlying domination is not victory. It is succession.

VII. The IDT Sequence

The Ontological Armory belongs between seeing and acting: Systemic Immersion, entering the situation without prematurely solving it — Forensic Systems Cartography, reconstructing what happened, what persists, who participates, where power accumulates — the Ontological Armory itself, rotating the object through structure, power, force, governance, cybernetics, ecology, and meaning to watch different causal worlds appear — an Intervention Repertoire generated for each causal world — a Portfolio of Wagers, explicit causal bets rather than the cleverest idea — Systemic Action, applying force where leverage warrants it — and Systemic Commitment: observing what reality does in response, stewarding consequences, learning, adapting, remaining accountable.

VIII. The Master Lesson

The novice asks what should we do. The designer asks what might we make. The systems thinker asks where is the leverage. The organizer asks where is the power. The lawyer asks what can be compelled. The cybernetician asks what governs the feedback. The ecologist asks what conditions reproduce this pattern. The philosopher asks what kind of world are we assuming this is.

The interventionist learns to ask all of them before deciding where to place their weight. That is ontological literacy — not knowing more theories, but knowing that the world changes depending upon what you believe it is made of.
