The Eight Epistemic Lenses

Derived from GoldBerry's ACST adaptation, the lens framework can be applied to any public communication — an article, a press release, a policy paper, a model card, a syllabus. Each lens is a theory of what should have been present, made operational.

The eight lenses in about a minute — silent kinetic type. Each lens has its own page below.

Why lenses, and why eight

An omission can only be detected against an expectation. "Something is missing" is meaningless without a theory of what belonged. The lenses supply that theory in plural: eight distinct vantage points, each of which makes a different class of absence visible. They are not a checklist of topics but a set of positions to look from — consistent with the standpoint-theory premise in the framework's philosophical grounding that marginal positions reveal what the centre cannot see.

The lenses are architecture, not garnish (Principle 4): an audit that skips a lens is incomplete by definition, and must say so. The eighth lens is structurally distinct from the first seven — it audits the framework's own analysis as well as the source, which is why it runs last.

The lenses

Lens	Core question	Corrects
1. Indigenous Knowledge	Whose embodied, relational knowledge is missing?	Erasure of embodied, relational epistemologies
2. Deep History	What historical processes produced this present?	Civilisational amnesia and temporal blindness
3. Cross-Cultural Wisdom	Which perspectives were flattened or translated away?	Universalist flattening of cultural difference
4. Scientific Evidence	What does evidence show, and what are its limits?	Untethered speculation and scientism's blind spots
5. Artistic Perception	What modes of attention are invited or foreclosed?	Reduction of knowledge to propositions
6. Future Modelling	Whose futures are centered? Who decides?	Static analysis ignoring temporal trajectory
7. Marginalised Voices	Who is not at the table?	Structural exclusion from knowledge production
8. Trickster Knowledge	What truth appears when the story is inverted, mocked, or followed to its absurd edge?	Narrative rigidity, solemn consensus — including the framework's own

What each lens produces

A lens pass is not an impression; it is a structured record with four required components:

Findings: What is present, viewed from this lens — the perspectives, contexts, and evidence the communication does include.
Gaps: What is missing that this lens reasonably expected — named specifically, with the expectation justified, so the gap is contestable rather than rhetorical.
Evidence: Quotes and page references anchoring both findings and gaps to the actual text. An unanchored gap claim is itself an invented claim, which the second refusal forbids.
Score: 0–100 with written justification, plus a status: satisfied, partial, absent, or not-applicable. The justification is the deliverable; the number is an index into it. Scores exist to make audits comparable and disagreements precise, not to rank communications on a leaderboard.

Lens 8 returns one additional component: a framework self-audit — where the other seven findings, or the audit's own composing voice, has gone solemn or closed. A non-empty self-audit means the audit's tone is reworked before it ships.

Reading lens scores

As a shared convention across all eight lenses: 0–24 means the lens's perspective is structurally absent and unacknowledged — any score below 25 is additionally flagged as a critical blindness; 25–49 means it is gestured at — mentioned, but without consequence for the communication's framing; 50–79 means it is substantively present and shapes the framing; 80–100 is reserved for communications where the perspective is present and governs its own representation. Where a lens genuinely does not bind, the recorded status is not-applicable — a judgement, never a skip. The eight scores together feed the plurality index in the evaluation pipeline. (The CMR composite is a separate instrument and keeps its /10 scale.)

A lens is not a quota. Not every communication must contain all eight perspectives to score well — a chemistry paper is not impoverished for lacking a futures section. Each lens page describes when the lens binds strongly, weakly, or not at all. What is never optional is running the lens and recording the judgement.

Beyond eight: the named absences

Eight lenses are a selection, not an exhaustion. Eight is still finite; epistemic space is not — and Lens 8 itself does not close the framework, it disciplines its seriousness. The framework therefore keeps a public list of candidate gaps: perspectives it knows it cannot yet reach. Currently named:

Ecological Intelligence: Non-human systems as knowledge-producing entities in their own right — not just objects of Indigenous knowledge about them.
Somatic Knowledge: The body as epistemic site: trauma, muscle memory, proprioception, gut knowledge.
Mathematical / Formal Knowledge: Proof, formal systems, and logical structure as an epistemology of their own.
Developmental Epistemology: How children know, and how knowledge develops — not just what adults have settled on.

These are not defined lenses; they are named absences — acknowledgements that the framework has edges. If a communication demands a perspective the eight cannot reach, the audit says so: naming what is outside the frame is itself a lens correction, and proposing a definition for any of these is a standing item in the Invitation.
