A power, disposition, or function exists in a bearer continuously but manifests only when its triggering conditions are met — salt has its solubility while dry in the jar, a fuse its breaking-current while no current flows — so the capacity is real and predicable independently of any manifestation.
How would you explain it like I'm…
The Hidden Can-Do
Sugar can dissolve in water. Even while it's sitting dry in the jar, it already 'can' dissolve, just waiting for water. The ability is real the whole time, but you only see it happen when you add the water.
The Waiting Ability
Some things have an ability that's always there even when nothing is happening. A glass can break, sugar can dissolve, a person who can vote can vote, even between elections. The ability stays inside the thing the whole time; it only shows up when the right thing triggers it. When the glass actually breaks, nothing new appeared inside it; it just finally did the thing it could always do. So you shouldn't say a glass 'is a breaking' or call sugar one single dissolving; the ability and the moment it happens are two different things.
Real Until Triggered
A Latent Realizable Capacity is a real ability that a thing always has, but which only shows itself under specific conditions. Salt has its solubility while sitting dry; a fuse has its breaking-current while no current flows; a shareholder has voting power between meetings; a function exists in code whether or not it's been called. The property is genuinely true of the thing even when nothing is happening, which makes it different from just describing the thing right now ('the salt is in the jar') and from a one-time past event ('the salt dissolved yesterday'). Realization is the event that turns the standing ability into an actual happening, and when the trigger fires, the thing's visible state doesn't suddenly change, its capacity just gets exercised. The common mistake is mixing up the ability with one instance of it, like treating a single failure as proof of a disposition instead of one test among many you haven't run.
A Latent Realizable Capacity is a dependent feature of some bearer, a power, disposition, role, or function, that exists in the bearer continuously but only manifests under specifying conditions. The structural commitment is that the property is real and predicable even when no manifestation is occurring: salt has its solubility dry in the jar, a fuse has its breaking-current with no current flowing, a shareholder has voting power between meetings. Realization is the event that converts the standing capacity into an actual occurrence; crucially, nothing in the bearer's current observable state changes when the trigger fires, what changes is that the standing capacity is exercised. The construct forces four design moves: name the bearer that carries the capacity, the triggering conditions that must hold, the manifestation pattern that occurs when triggered, and the persistence regime governing whether the capacity survives, depletes, fatigues, regenerates, or transfers across manifestations. Omitting any one breeds confusion, most often conflating a manifestation with the bearer ('this is a fragile object') or the capacity with its realization (treating one failure as proving a disposition). This dispositional mode of predication is structurally distinct from pure descriptive predication ('the salt is in the jar') and pure historical predication ('the salt dissolved yesterday'). It is the standing license to make conditional claims about a bearer's behavior, a license that holds independently of observation. That is why one and the same structure underwrites reasoning about unobserved objects, untested code paths, and unexercised rights.
Physics and chemistry: solubility, fragility, conductivity, half-life, melting point — dispositions ascribed whether or not the manifestation occurs.
Biology and medicine: enzymatic activity, immune memory, genetic predisposition that elevates risk only under co-occurring triggers, pathogen virulence.
Engineering: the rated breaking-current of a fuse, the yield strength of a beam, design margins as headroom before a limit triggers failure.
Computer science: lazy evaluation (a thunk's capacity to produce a value on demand), promises and futures, object capabilities.
Law: legal powers — to make a will, to vote, to bind an organization — and dormant succession authority.
Economics: option value, contingent liabilities, and credit lines as latent borrowing power.
Makes explicit what is asserted to exist even when nothing is happening, resolving disputes about whether a property is "really there" by naming the dispositional mode of predication and forcing specification of trigger conditions.
Compresses an unbounded counterfactual space into a finite description: "soluble in water" plus a trigger captures the whole family of dissolving situations at once, the same move as a type signature or a risk register.
A disposition warrants counterfactual entailment ("if trigger T occurred, manifestation M would occur") and decouples existence from observation, licensing inference about unobserved properties, untested code paths, and unexercised rights.
Digital finance from security: the unforgeable-capability token (authority that exists whether or not exercised) transferred into digital financial rights.
Public health from reliability: cataloguing failure dispositions transferred into population risk stratification (susceptibility, immunity).
Engineering from finance: pricing latent options transferred into real-options systems design.
A thunk in a lazy language has the standing capacity to compute a value continuously, whether or not it is ever forced; under call-by-need it depletes on first evaluation, under call-by-name it survives every demand — and the thunk is never identical to its value.
Latent Realizable Capacity is not Attentional Capacity because the prime is a standing disposition that fires under a trigger, whereas attentional capacity is a finite resource ceiling consumed in use.
Latent Realizable Capacity is not an Affordance because the prime is the bearer's own disposition independent of any agent, whereas an affordance is an action possibility a bearer offers an agent.
Latent Realizable Capacity is not Optionality because the prime manifests mechanically when its trigger is met with no chooser, whereas optionality is the value of a right to choose exercised by a decision-maker.
