What 6 Types of Information Gaps exist?

The 6 Information Gaps are: Conceptual Gaps, Boundary Gaps, Framing Gaps, Vocabulary Gaps, Temporal Gaps, and Cross-Domain Gaps. Why this differentiation? Not all information gaps are the same. Treating them as a single category would produce a flat analysis that misses the distinct strategic value of each type. The Ignorance Graph methodology distinguishes six gap types, each with a different origin, different visibility, and different approach to occupation.

1 — Conceptual gaps

A concept exists in practice — in expert communities, in applied work, in emerging research — but has never been named, defined, and indexed. There is no established vocabulary for it, which means there is no query that would currently find it. The concept is not unknown to the people who use it; it is unknown to retrieval systems because it hasn’t been formally articulated.

Strategic property: Naming a conceptual gap establishes definitional primacy. The entity that provides the first indexed definition owns the vocabulary.

2 — Boundary gaps

These exist at the edge of established consensus — the questions that are clearly implied by everything the consensus says, but that no existing result directly addresses. The consensus points toward them without answering them.

Strategic property: Boundary gaps are discoverable through systematic analysis of the SERP Consensus Layer. They have implied demand from adjacent searches.

3 — Framing gaps

The topic exists and is extensively covered — but always through the same frame. A different, equally valid framing of the same subject has no established representation in the index. The knowledge is not absent; the angle is.

Strategic property: Framing gaps require the least new knowledge to occupy — the subject is established. The work is reframing, not research.

4 — Vocabulary gaps

A phenomenon is discussed in the corpus under several different terms, none of which has become the canonical vocabulary. There is no single authoritative definition that the others reference. The first entity to establish the canonical term consolidates scattered authority.

Strategic property: High leverage per word. A single precise definition can become the reference for an entire fragmented terminology landscape.

5 — Temporal gaps

The knowledge existed and was indexed, but has become outdated without replacement content being produced. The consensus reflects a previous state of knowledge. The gap is not absence — it is obsolescence that hasn’t yet been addressed.

Strategic property: Often underestimated. The existing consensus position makes the gap invisible, but its content is no longer accurate.

6 — Cross-domain gaps

A concept is well established in one domain but has never been formally applied to another. The knowledge transfer hasn’t happened in indexed form. No query from domain B would currently find the relevant knowledge from domain A.

Strategic property: Cross-domain gaps often represent the highest-value positions — they connect established authority with entirely unoccupied territory.
