A compilation with references of some classifications, systematics and other orders of what is not known.
By Ann Kerwin and Marlys Witte (Q-cubed Programs: What Is Ignorance?). According to Ann Kerwin the Map of Ignorance was developed by her circa 1983. It has later been presented in 1985 and 1986 together with Marlys Witte.
This little map has traveled the globe. On its clones have scribbled Nobel Laureates, U.N. delegates, educators, physicians, artists, students, politicians, inventors, scientists, poets and ponderers from many walks of life. It's just a prop, a cosmic swerve, a silly prompt for exploration and celebration of the fertile home territory of learning. (Ann Kerwin)

Abstract: Our ignorance encompasses, at least, all the things we know we do not know (known unknowns); all the things we do not know we do not know (unknown unknowns); all the things we think we know but do not (error); all the things we do not know we know (tacit knowing); all taboos (forbidden knowledge); and all denial (things to painful to know, so we suppress them). Medical ignorance seems especially threatening to many of us. If, however, we are to cope with our vast ignorance of the human body, its powers and processes, we must learn to acknowledge our nescience and optimize it. To do so, we need to rethink the nature and interrelations between knowledge and ignorance. We need to expand our capacities for self-learning and refine abilities to map our complex experience.

We are all ignorant in a variety of ways, to various degrees, with respect to specific issues, problems and questions. In fact, it is the increasing awareness of our ignorance of what there remains to know that is most special about the learning process. A taxonomy of ignorance provided by Smithson (1989:9; and 1993:135) suggests a variety of forms:

Abstract: Discusses scientific ignorance and uncertainty. Highlights include approaching knowledgeable ignorance, including a taxonomy of ignorance and uncertainty frameworks and measures; social constructivism, subjectivity, and scientific realism; strategies for working with scientific ignorance; and frameworks for ignorance representation.
Ignorance Level | Description | Knowledge Required |
---|---|---|
Combinatorial | Computational task too difficult, e.g. problem with 1040 variables. | Mathematics model available; use of supercomputers. |
Watsonian | Cannot make the connection from all the clues; solution method incomplete. | Method for determining the important facts from the unimportant ones, and drawing the right conclusion. |
Gordian | King Gordius tied a knot for the future king of Asia to untie. Alexander the Great was able to “untie it” by cutting the knot with his sword, thus solving the problem in an unusual way. | Lateral thinking; are there “rules” to be broken? |
Ptolemaic | Attributed to the Greek mathematician and astronomer, Ptolemy, whose model of the universe centered around a stationary earth. | Evidence and observation of reality. |
Magical | “No one knows how it works, but everyone knows that it works”, e.g. the use of Aspirin and other similar drugs. | Trial and error. |
Dark | No model is available but one is aware of the issues, e.g. “What is Life?”, “Consciousness”, etc. | Future of Science |
Fundamental | Unaware of issue. (Ignorance is bliss!) |
Ignorance can be construed as the state of there being corresponding knowledge 'out there' inaccessible to the decision maker. Holtzman (1989) identified several levels of ignorance by describing the equivalent knowledge paradigm within which it occurs. Table 1. [shown here] presents an expanded version of the Taxonomy.

Ignorance of the irreducible variety exists because of two ever present factors. The first is owing to complexity. Here, an outcome is unexpected because the complexity surrounding underlying processes of certain dynamic systems precludes the possibility of gaining a comprehensive understanding of them. In the second instance, irreducible ignorance stems from the emergence of novelty. Novelty arises because systemic parameters are forever evolving. This leads to adaptive and somatic change in the short and medium terms, and genotypic change (bifurcation) in the long term. Novelty results in irreducible ignorance because, in not knowing the initial boundary conditions governing the global system's evolutionary pathway, one cannot predict the future pathway of the global system in principle or in broad terms.

Abstract: People tend to hold overly favorable views of their abilities in many social and intellectual domains. The authors suggest that this overestimation occurs, in part, because people who are unskilled in these domains suffer a dual burden: Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it. Across 4 studies, the authors found that participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. Although their test scores put them in the 12th percentile, they estimated themselves to be in the 62nd. Several analyses linked this miscalibration to deficits in metacognitive skill, or the capacity to distinguish accuracy from error. Paradoxically, improving the skills of participants, and thus increasing their metacognitive competence, helped them recognize the limitations of their abilities.
