Decoding Prompt 28 – “To what extent is objectivity possible in the production or acquisition of knowledge?”
TOK Exhibition Prompt 28 sits at the heart of the Theory of Knowledge course because it confronts one of epistemology’s most persistent tensions: can the producers and acquirers of knowledge ever truly step outside their own perspective? The prompt pushes you beyond a yes/no answer and invites you to examine the methods, safeguards and limits that shape how objectivity is pursued in science, history, journalism and technology. For a strong exhibition, each of your three objects must reveal a different angle on this — whether through experimental method, archival practice, peer review, editorial standards or algorithmic decision-making.
A top-scoring IB TOK exhibition on Prompt 28 does three things well: it links each object to a specific real-world context, it justifies why that object illustrates the prompt through a clear knowledge claim about objectivity, and it connects back to an optional theme or area of knowledge.
TOK Exhibition Objects for Prompt 28
Each example below includes the object, linked optional theme, examiner-written rationale, and a knowledge question to extend your analysis.
Double-Blind Study Methodology Description
The double-blind study, a methodological approach where neither the participants nor the experimenters know who is receiving a particular treatment, exemplifies an attempt to achieve objectivity in scientific research. This methodology aims to eliminate bias and ensure that the results of the study are as unbiased and reliable as possible. It underscores the challenges of maintaining objectivity in knowledge production, especially in fields where human subjects are involved, and highlights the methods developed to mitigate subjective influences on research outcomes.
Stuck picking 3 objects that actually score in the top band?
Most IB students lose 4–6 marks because their objects don’t clearly link to the prompt or the optional theme. Our IB-certified TOK examiners fix this in one 1:1 session on the Sev7n LMS.
- Rubric-based review of your current object choices
- Live examiner feedback on rationale + knowledge question
- Recorded sessions on our LMS — rewatch anytime
- Ready-to-submit commentary within 950-word limit

A Historian’s Archive with Primary Sources from Multiple Perspectives
An archive that collects primary sources from diverse perspectives on a historical event illustrates the efforts to achieve objectivity in historical knowledge. By incorporating documents, testimonies, and artifacts from various sides of an event, historians aim to construct a more balanced and comprehensive understanding of the past. This object reflects on the inherent challenges of objectivity in history, where the interpretation of events is influenced by the historian’s perspectives, biases, and the availability of sources.
Falling behind across 6 subjects + TOK + EE + CAS?
The IB workload breaks most students between DP1 and DP2. Sev7n’s 170+ IB examiners deliver live 1:1 tutoring across every IBDP subject — Sciences, Maths, Economics, Business Management, Psychology, English, and more — all on one LMS.
- Expert help for Paper 1, Paper 2, Paper 3 & Internal Assessments
- IA topic selection, data analysis, and draft marking
- Past paper practice with examiner-style feedback
- Predicted grade improvement — most students gain 2+ points
Peer Review Process Flowchart for a Scientific Journal
The peer review process is central to the scientific method, serving as a critical checkpoint for the objectivity and quality of research before publication. A flowchart detailing this process can highlight the steps taken to ensure that knowledge production in science meets rigorous standards of evidence and reasoning, free from individual biases as much as possible. This object invites discussion on the effectiveness and limitations of peer review in maintaining objectivity, including potential biases within the peer review process itself.
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 28
Two additional examiner-written object examples to help you finalise your TOK exhibition selection.
News Media Editorial Guidelines Document
Editorial guidelines set by news organisations aim to uphold standards of objectivity and impartiality in journalism. These documents often detail practices for fact-checking, source verification, and the separation of news from opinion, highlighting the media’s role in providing objective information to the public. This object serves as a basis for exploring the challenges news outlets face in maintaining objectivity, especially in an era of increasing polarisation and accusations of media bias.
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
Algorithmic Trading System Documentation
The documentation for an algorithmic trading system, which uses complex algorithms to execute trades at speeds and volumes beyond human capability, illustrates the pursuit of objectivity in financial markets. These systems are designed to make decisions based on data analysis without the influence of human emotions or biases, aiming to optimize trading strategies based on objective criteria. This object highlights the technological efforts to achieve objectivity in knowledge application within the context of financial trading, underscoring the challenges and implications of relying on technology to remove subjective human influence from decision-making processes.
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.

Knowledge Questions for Prompt 28
Use these knowledge questions to strengthen the analytical depth of your exhibition commentary.
Is complete objectivity ever achievable, or is it only ever an aspiration we approach asymptotically?
How do the methods of the natural sciences differ from those of the human sciences in pursuing objectivity?
To what extent can institutions like peer review or editorial boards enforce objectivity?
Does the language we use to describe phenomena pre-bias what we can know about them?
Are technological and algorithmic systems more objective than human knowers, or do they conceal their biases?
Can a knower committed to a value system still produce objective knowledge?
How to Score High on Prompt 28
Three strategies our IB examiners use when coaching students through the TOK exhibition.
Anchor each object to a real procedure
Objectivity is procedural — examiners reward objects that show a specific, named method (a clinical trial protocol, a particular archive, a journal’s peer-review process), not vague references to ‘science’ or ‘the news’.
Address the limits, not just the ideals
The top markband is reached when you acknowledge how each object both advances and falls short of objectivity. Mention the residual biases as well as the safeguards.
Match each object to a different optional theme
Spread your three objects across distinct optional themes so your commentary can showcase varied perspectives on objectivity — technology, language, indigenous societies, the knower.
