IB Theory of Knowledge examples are valuable when they expose a genuine problem involving evidence, certainty, interpretation, perspective, or values. The current TOK course examines five areas of knowledge, usually called AOKs: history, the human sciences, the natural sciences, the arts, and mathematics.
This guide provides a real-world example for each AOK and explains how to turn factual material into analysis for a TOK essay, exhibition, or classroom discussion.
What are the TOK areas of knowledge?
An area of knowledge is not simply an IB subject. It is a field in which communities use characteristic methods and standards to produce, test, interpret, and communicate knowledge.
Mathematicians establish conclusions through proof, while historians interpret surviving evidence about events that cannot be repeated. These methods serve different purposes, so one is not automatically more reliable than the other.
The official IB TOK subject brief identifies five compulsory AOKs:
| Area of knowledge | Characteristic methods | Central TOK tension |
|---|---|---|
| History | Source analysis, corroboration, contextualization | Evidence constrains interpretation without producing one complete account |
| Human sciences | Experiments, surveys, observation, statistics | Human behaviour can be studied systematically but varies across contexts |
| Natural sciences | Observation, experimentation, modelling, peer scrutiny | Scientific knowledge is reliable without being permanently certain |
| The arts | Creation, performance, interpretation, criticism | Meaning can be plural without every interpretation being equally justified |
| Mathematics | Axioms, definitions, deduction, proof | Formal certainty may weaken when mathematics is applied to imperfect data |
Ethics is not a separate AOK in the current course, although ethical questions arise within every AOK. Resources listing eight AOKs generally describe an earlier TOK syllabus.
Natural sciences example: changing mask guidance
The natural sciences investigate the physical world through observation, measurement, experimentation, modelling, and collective scrutiny. Conclusions remain open to revision when researchers obtain new evidence or develop better explanations.
During the COVID-19 pandemic, mask guidance changed as evidence developed concerning transmission, asymptomatic infection, mask types, and public behaviour. The World Health Organization's June 2020 interim guidance acknowledged limitations in the available direct evidence while recommending a risk-based approach.
A useful knowledge question is:
Does the provisional nature of scientific knowledge reduce or increase its reliability?
Changing advice may weaken confidence when people expect stable answers. However, revision in response to stronger evidence demonstrates an important scientific safeguard. The case distinguishes certainty, which may be unavailable, from justification, which can be strong relative to the evidence available at the time.
Human sciences example: prospect theory
The human sciences systematically investigate people and societies. Their disciplines include psychology, economics, sociology, anthropology, and political science, but they do not all use identical methods.
Daniel Kahneman and Amos Tversky used experiments to show that decisions under uncertainty can depart predictably from traditional assumptions of rational choice. Their prospect theory proposed that people evaluate outcomes relative to a reference point and often respond more strongly to losses than equivalent gains.
The Nobel Prize account of Kahneman's research explains how experimental evidence challenged established economic assumptions. It also raises an important question:
To what extent can controlled experiments produce reliable knowledge about behaviour outside the experiment?
Experiments isolate variables and reveal patterns, but participants may react to artificial conditions, framing, or awareness that they are being observed. Human-science findings can therefore be well supported without becoming exceptionless laws that apply equally across every population and culture.
History example: interpreting the Benin Bronzes
History constructs knowledge about a past that cannot be directly observed or experimentally repeated. Historians work with documents, objects, photographs, oral testimony, and archaeological evidence, all of which require interpretation.
British forces looted thousands of royal objects during the 1897 raid on Benin City. Many subsequently entered museums and private collections. The Smithsonian's research on the Benin collections combines material evidence, colonial records, trade accounts, provenance research, and oral histories.
A strong knowledge question is:
How does the perspective of a source affect its value as historical evidence?
A British officer's account might provide useful dates while using language that justifies colonial violence. Edo oral histories may preserve knowledge excluded from colonial archives, but they also require contextual interpretation. Perspective does not automatically invalidate evidence; instead, it becomes part of what historians evaluate.
Language also shapes present understanding. Describing an object as an acquisition, war trophy, or looted work implies different conclusions about ownership and responsibility.
The arts example: Banksy's self-shredding work
Knowledge in the arts can be created and communicated through form, symbolism, performance, emotion, and cultural convention. Artistic understanding is not limited to factual propositions.
In October 2018, Banksy's Girl with Balloon partially passed through a shredder concealed in its frame immediately after an auction sale. The altered piece was authenticated and renamed Love is in the Bin. Sotheby's account of the event describes it as the creation of a new work through the apparent destruction of another.
This supports the question:
To what extent does knowledge of an artist's intention determine an artwork's meaning?
Knowledge of Banksy's plan clarifies why the mechanism existed, but it cannot settle every interpretation. Viewers may see criticism of the art market, a publicity performance, or self-destructive art. Interpretive plurality does not mean that anything is acceptable; stronger readings use evidence from the work, context, and artistic practice.
Mathematics example: England's 2020 grading algorithm
Mathematics develops knowledge through definitions, axioms, deduction, and proof. Within a formal system, a valid proof can establish conclusions with unusual certainty. Applied models are less straightforward because their results depend on assumptions, selected variables, and imperfect data.
When examinations in England were cancelled in 2020, a statistical model calculated A-level grades using information including teacher assessments, candidate rankings, prior attainment, and schools' historical performance. A UK Parliament research briefing reported that many results were lower than teachers' centre assessment grades. Following widespread objections, the model was withdrawn.
A useful knowledge question is:
Can a mathematically consistent model produce an unjustified conclusion?
A calculation can operate exactly as designed while producing outcomes considered unfair. Mathematics cannot independently decide which variables should matter or whether a school's previous performance should influence an individual. This distinguishes mathematical validity from real-world validity: correct calculation does not guarantee defensible assumptions or purposes.
How to turn examples into TOK analysis
Weak TOK writing reports what happened. Strong writing explains what a case reveals about the production, justification, interpretation, or limitations of knowledge.
Use this sequence:
- Identify the case precisely. Name the study, artwork, source, model, or event.
- State the knowledge claim. Explain what someone claims to know.
- Identify the method or evidence. This might be an experiment, proof, document, testimony, model, or artistic convention.
- Introduce a limitation or competing perspective. Ask what the method excludes or what another knower could challenge.
- Evaluate the implications. Consider reliability, certainty, objectivity, interpretation, values, or responsibility.
- Return to the prompt. Explain explicitly how the example supports your answer.
For example, stating that WHO changed its guidance is descriptive. An analytical version would argue that revising guidance suggests scientific reliability depends less on unchanging conclusions than on transparent procedures for responding to new evidence.

Common mistakes with TOK examples
Treating one example as universal proof
A single case rarely proves a conclusion about an entire AOK. Banksy's work can illuminate artistic intention, but it cannot establish how every artwork acquires meaning. Use cases to test and qualify claims.
Selecting a topic rather than a case
COVID-19, colonialism, and artificial intelligence are broad topics. Narrow them to a particular document, object, experiment, system, or controversy that can be researched accurately.
Using an outdated framework
The current course has five AOKs. Ethics, religion, and indigenous knowledge remain relevant, but they are not separate AOKs in the current structure. RevisionDojo TOK Study Notes organize concepts around the present course.
Copying prepared analysis
TOK coursework exemplars can demonstrate effective reasoning, but your argument and wording must remain your own. Verify facts, cite sources, and avoid treating a model response as a script.
Choosing examples for the essay and exhibition
For the TOK essay, select cases that support sustained evaluation and competing interpretations. A few carefully analysed examples are generally more useful than numerous passing references.
For the TOK exhibition, use a specific object with an identifiable real-world context. A particular museum label, guidance document, or personally used object is stronger than a generic image representing science or culture. The RevisionDojo guide to the 35 exhibition prompts explains how three distinct objects can be connected to one prompt.
Before committing to an example, check that you can explain its context, identify its knowledge issue, evaluate more than one perspective, and connect it directly to the prescribed title or exhibition prompt.
Conclusion
Effective IB Theory of Knowledge examples make differences between AOK methods visible. Choose a precise case, identify the relevant evidence and assumptions, evaluate competing perspectives, and connect your conclusion directly to the prompt.
