Objects (DP IB Theory of Knowledge): Revision Note

Selecting effective objects

• An acceptable object for an exhibition is a real item that exists in the world, and that can be used as evidence to help you explore your chosen prompt

  • Your object should not be an idea or concept, e.g. “justice”, “love”, “time”

Choosing specific objects

• The objects must have a real-world context, i.e., a clear origin or setting, so you can explain what it reveals about knowledge in that specific context

  • Objects should be specific enough that an examiner can tell you are talking about a particular real-world example, not a general item

    • e.g. a named public health poster from a particular campaign rather than “informative posters about vaccines”

• Specific objects make justification easier because you can point to details that directly support your claims about knowledge

• Context turns an object into evidence because it lets you explain what the object shows about knowledge in a particular situation

  • Your context should be selective, meaning you only include details that you will use to justify the link to the prompt

• Generic objects tend to lead to generic ToK points because there is no clear context to ground your reasoning

Avoiding symbolic objects

• It is important to avoid symbolic objects, as they often lead to personal interpretation instead of evidence-based justification

• A symbolic object is an object chosen mainly for what it represents, rather than for what it does in a real-world knowledge context

  • e.g. if the prompt is about certainty, a student might choose a compass because it “symbolises direction”; the compass is then used as a metaphor for knowledge, rather than as evidence

• A common warning sign is when your explanation depends on phrases like “this represents” or “this symbolises”, rather than on what the object does in the real world

Ensuring that each object contributes differently

• Aim for three objects that help you explore the same prompt in three meaningfully different ways, so your justification does not become repetitive

• A quick check is whether you can write three different “because” sentences, one for each object, without repeating the same logic

Do not force an object to fit a prompt

• Forcing happens when you choose an object you like and then try to stretch the prompt so it seems relevant

  • If you keep rewriting the prompt in your own words to make the object fit, that is usually a sign the match is weak; the prompt must be explored in the exact wording that is given in the IB guide; you cannot change the wording.

  • If an object only fits the prompt through vague wording, it is usually better to replace the object or rethink the prompt

• Forced links often sound like object description followed by a sudden ToK claim, without clear evidence that the object actually supports that claim

Objects vs images of objects

• Your school may choose to have an in-person exhibition in which you can bring the actual objects. However, you need to submit a written commentary to IBIS for moderation, so you need to include clear images/photographs of the objects in this commentary.

• The images should be cited as any source is cited in your IB work. If the photo is one you took yourself, include the citation stating so and the date on which you took the photo (“Source: Author’s own photo, May 2026)

• Make sure the image shows the actual object you are discussing, rather than a vague stock photo that could represent anything. Again, generic objects do not work; you need specific objects in real-world contexts, so, for example, a stockphoto of a cell phone is not appropriate

Justifying the objects

• Your justification of an object should include:

  • justification rather than description: why have you chosen this object to explore this prompt?

  • an explanation of what the object shows about knowledge

  • clear links to the prompt

Justification vs description

• It is essential that your exhibition consists of justification, and not just description, of each object

  • Description tells the examiner what the object is, whereas justification explains:

    • why the object is relevant to the prompt

    • what it shows about knowledge in its real-world context

  • Description is useful only when it acts as evidence that you immediately use to provide justification

• A quick way to check that you are justifying is to ask whether each sentence is answering “so what?” for the prompt

  • If your writing could be copied onto a museum label without changing anything, it is probably description rather than justification

Linking the objects to knowledge

• For each object, you should explain what it demonstrates about a relevant knowledge issue (this issue will depend on your chosen prompt); it can be very useful to use the ToK key concepts in forming your claims (evidence, interpretation, certainty, truth, power, justification, explanation, objectivity, perspective, culture, values, responsibility)

• Consider the following:

  • name the specific knowledge issue or key concept the object reveals in its real-world context, e.g. reliability, bias, authority, ownership, ethical limits, power

  • state one clear knowledge claim that the object suggests

  • identify a detail from the object as evidence, e.g. a feature, wording, data, design choice or omission, and explain why this detail matters

  • explain who is involved in the knowledge process shown by the object, e.g. producer, expert, institution, a community of knowers

  • show how the object shapes what is accepted as knowledge in that context, e.g. persuades, filters, legitimises, excludes, distorts

  • identify what could challenge the knowledge shown by the object, e.g. alternative evidence, different perspectives, conflicts of interest or methodological limits, and explain the impact on trust/validity/reliability/certainty

The importance of context

• Your justification should be rooted in what the object does in a particular real-world setting

• Use contextual details that strengthen knowledge claims, such as

  • who produced the object and for what purpose

  • who uses it, trusts it or challenges it

  • what audience it was intended for

  • what happens when the object is accepted, rejected or misused

• Avoid adding background detail that does not feed into your reasoning about knowledge, because it pulls you back into description and wastes word count

Linking the objects to the prompt

• For each object, make the link to the prompt explicit early on in your explanation, so the examiner can immediately see what the object is doing in your argument

• The relationship should not be implied through vague wording, but should be stated clearly

• In order to make clear links you should make explicit references to the prompt

  • Use the prompt’s key words directly in your writing so it is obvious you are linking to it

    • Paraphrasing can be useful for explaining, but you should keep returning to the exact wording to avoid drifting into a different question

  • Refer back to the prompt throughout the explanation of each object, not just once at the start of the exhibition

  • A practical habit is to include a sentence that re-anchors your point, such as “This matters for the prompt because…”

• Examples of justification and explanation, in comparison to description, are shown in the table below

  • Note that these justifications are just short examples, and would need to be explored in more depth in an exhibition

Explaining why the objects were chosen

• Your justification should make it clear why this object is a good choice for exploring the prompt, rather than just an object that fits the topic

• A good “why this object?” explanation usually includes

  • what specific evidence the object provides that you can use in your reasoning

  • why that evidence matters for the knowledge issue raised by the prompt

  • why this object is more effective than a generic alternative

• If the only reason you can give is “it is interesting” or “it shows this topic”, the justification is usually too weak
