Decoding Prompt 6 – “How does the way that we organise or classify knowledge affect what we know?”
IB TOK Exhibition Prompt 6 pushes at a subtle but powerful idea: the architecture of knowledge shapes the knowledge itself. Whenever we classify — into Dewey Decimal categories, Eurocentric world maps, algorithmic recommendations, or medical diagnostic categories — we foreground some relationships and hide others. Your three objects must each illustrate how a specific classification system shapes what can be seen, asked, and known.
A strong exhibition on Prompt 6 identifies different structural choices and traces their downstream epistemic effects. The best objects come from classification systems that students encounter daily: libraries, maps, social media algorithms, dictionaries, and health-tracking apps. Rich linked themes include Knowledge & Language, Knowledge & Technology, and Knowledge & Indigenous Societies.
TOK Exhibition Objects for Prompt 6
Each example below includes the object, linked optional theme, examiner-written rationale, and a knowledge question to extend your analysis.
A Library’s Dewey Decimal Classification Guide
The Dewey Decimal System, as a method for organising books and resources in a library, serves as a tangible representation of how classification systems in knowledge repositories influence access to and perceptions of knowledge. This guide sparks discussion about the implications of categorising knowledge according to a predefined system, including how such systems might prioritise certain types of knowledge over others, potentially shaping the knower’s exploration and valuation of information. Critics have long noted that Dewey’s original structure disproportionately privileged Western Christian thought and allocated comparatively less taxonomic space to non-Western religions and knowledge systems — a structural bias that reshapes a researcher’s sense of the intellectual landscape. The object prompts consideration of how language and classification interact to structure our understanding of the vast landscape of human knowledge, and of how the implicit hierarchies embedded in any classification system silently govern what gets foregrounded and what gets buried.
Stuck picking 3 objects that actually score in the top band?

An Algorithm Code for Content Recommendation Systems
Content recommendation algorithms, like those used by streaming services or social media platforms, exemplify the technological organisation of knowledge and its impact on individual consumption patterns. These systems classify and recommend content based on user behaviour, creating personalised information landscapes that can result in echo chambers or filter bubbles affecting what we know and perceive about the world. This object demonstrates a uniquely modern dynamic: classification is no longer a one-time taxonomic decision made by librarians but a continuous, automated, and invisible process that reshapes each user’s epistemic horizon in real time. The algorithm encourages a TOK analysis of the relationship between technology, knowledge organisation, and the shaping of personal and collective knowledge landscapes — and raises pointed questions about whether we can meaningfully talk about an “objective” world when the information each of us sees has been pre-sorted by machine.

- Past paper practice with examiner-style feedback
- Predicted grade improvement — most students gain 2+ points
A World Map Centred on the Pacific Ocean
Traditionally, world maps are Eurocentric, placing Europe near the centre and distorting the relative sizes of continents through the Mercator projection. A Pacific-centred map challenges these conventional geographical perspectives and invites students to consider how different ways of organising geographical knowledge can influence our understanding of the world. It raises TOK questions about the impact of cultural viewpoints on knowledge classification, especially in how we conceptualise space, territory, and cultural significance. A Pacific-centred map foregrounds Oceania, indigenous sea-routes, and the centrality of maritime societies — all of which are peripheral in conventional maps. This object therefore encourages reflection on the diverse ways knowledge can be structured and on how the very act of choosing a projection centre silently redistributes importance, visibility, and narrative weight.
Your IA or Extended Essay deadline is coming. Your draft isn’t top-band yet.
Internal Assessments and the Extended Essay carry serious weight in the final IB score — yet most students submit drafts that lose easy marks on structure, data analysis, and referencing. Sev7n’s examiners review every draft against the official IB rubric before you submit.
- Topic selection & research-question refinement
- Rubric-mapped feedback on every draft (Criteria A–E)
- Data analysis, methodology & referencing support
- Final polish to push your IA from a 5 to a 7
What Parents & Students Say About Sev7n
Hear directly from IB parents about how Sev7n transformed their child’s IB journey — from predicted 4s to final 7s.
My daughter was struggling with TOK exhibition and Chemistry HL — predicted 4s in both. After 4 months with Sev7n’s examiner tutors, she scored a 7 in Chem and 9/10 on exhibition. The LMS dashboard kept me in the loop every week. Worth every rupee.
We tried three big coaching centres in Dubai before finding Sev7n. The difference: actual IB examiners, not generic teachers. My son’s Economics HL teacher here has marked IB papers for 8 years. Game-changer for his IA and predicted grade.
What I love most is the auto-recorded sessions and weekly parent reports. I’m a working mom and can’t hover over my daughter’s shoulder — Sev7n’s LMS makes it easy to stay informed without being intrusive. TOK essay went from 3 to 8.
The free demo class itself was more useful than months of IB support elsewhere. The tutor didn’t just teach — she diagnosed exactly where my son was losing marks on Paper 2. Honest, professional, and genuinely examiner-level. Signed up the same day.
Our Singapore time zone was always an issue with Indian tutors. Sev7n matched us with a tutor who’s based in the UK and teaches in our window. My daughter’s Maths AA HL went from a predicted 5 to 7 in 6 months. Can’t recommend enough.
We’ve worked with 4 different TOK tutors before Sev7n. None came close. Their examiner gave my son a detailed marksheet mapped to the IB rubric — something no one else did. Final TOK essay: A (predicted C). That grade just saved his university offer.
2 More Objects for Prompt 6
Two additional examiner-written object examples to help you finalise your TOK exhibition selection.
A Social Media Newsfeed Algorithm Description
The algorithm that dictates the organisation and display of posts in a social media newsfeed exemplifies how digital platforms classify and prioritise knowledge. This description illuminates the impact of technological filters on our access to information and how we come to know the world around us. The crucial epistemic feature is that these algorithms classify information by optimising for engagement — clicks, watch time, shares — rather than by accuracy or importance. This means that content evoking outrage or tribal identity is systematically promoted above content that is balanced or dull but true. The object therefore illustrates that classification systems, when tied to commercial incentives, can distort collective knowledge in predictable directions. It encourages students to reflect on the ways technology mediates our interaction with knowledge and the implications for individual and collective understanding in a digitally connected era.
Tired of one-size-fits-all coaching centres that don’t really know IB?
Sev7n’s proprietary LMS pairs you with an examiner who’s actually marked IB papers. Every class is live, every session is recorded, and every parent gets a weekly progress report — all on one clean platform built for IB families.
- 100% live 1:1 or small-batch classes (never big-class chaos)
- Every session auto-recorded — rewatch, revise, repeat
- Weekly WhatsApp progress reports for parents
- Flexible time zones — tutors across India, UK, UAE, Singapore
A Personal Health Tracking App Interface
Health tracking apps organise and classify personal health data in ways that influence users’ perceptions of their well-being and health knowledge. The app’s interface typically foregrounds a handful of metrics — steps walked, calories consumed, hours slept, heart rate — while rendering invisible the dimensions of health it cannot measure: emotional state, relationship quality, meaningful work, or communal well-being. This object invites a TOK discussion on how the classification of health metrics shapes our understanding of health and influences decision-making. It prompts reflection on the implications of quantifying and categorising personal health information through technology, exploring both the benefits (personal awareness, early warning, motivation) and the limitations (reductionism, anxiety, surveillance) of such knowledge organisation for individual well-being — and on how the user’s lived sense of being healthy becomes subtly retrained by what the app chooses to measure.
Your school teacher can’t mark IB exam papers. Our tutors can.
There’s a massive difference between someone who teaches IB content and someone who actually marks IB exam scripts. At Sev7n, 170+ of our tutors are IB-certified examiners — which means they know exactly what scores, and what doesn’t.
- Verified IB examiners — not just IB teachers
- Deep rubric knowledge across HL, SL & all assessment objectives
- Insider insight into common examiner mistakes students make
- Personalised feedback that matches real IB markschemes

Knowledge Questions for Prompt 6
Use these knowledge questions to strengthen the analytical depth of your exhibition commentary.
Does the way we classify knowledge determine what we can know, or only how we know it?
Are classification systems neutral tools, or are they always shaped by the values of their creators?
Can a single object belong to two incompatible classifications, and what does this reveal about knowledge?
When algorithms classify knowledge for us, does responsibility for what we know transfer from us to them?
Does the rigidity of a classification system limit discovery, or does it enable it?
Is it possible to imagine knowledge that could exist outside any classification at all?
How to Score High on Prompt 6
Three strategies our IB examiners use when coaching students through the TOK exhibition.
Pick objects with a real-world context
Your object must be specific — “my grandfather’s 1998 copy of the Britannica” beats a generic encyclopedia every time. Examiners reward specificity.
Anchor to one optional theme per object
Don’t float between themes. Each object should clearly link to one optional theme or area of knowledge and stay consistent throughout.
Justify — don’t just describe
The top markband (9–10) is reached only when the commentary explains why the object illustrates the prompt, not just that it does.
