IB DP Core: Theory of Knowledge 5 β Questions and Answers
Question 1: In TOK, the 'coherence theory of truth' holds that a statement is true if:
- It corresponds directly to an observable fact in the world
- It fits coherently within a larger system of mutually consistent beliefs (Correct answer)
- It is useful and produces practical outcomes
- It is accepted by a qualified community of experts
Correct answer: It fits coherently within a larger system of mutually consistent beliefs
The coherence theory evaluates truth by how well a belief coheres or fits with a broader network of accepted beliefs.
Question 2: Which of the following would be considered a 'methodological assumption' in the Natural Sciences?
- The belief that God guides natural processes
- The assumption that nature is uniform and its laws apply consistently across time and space (Correct answer)
- The view that scientific theories areζ°ΈθΏ final and unchangeable
- The claim that all scientific knowledge is subjective
Correct answer: The assumption that nature is uniform and its laws apply consistently across time and space
Science presupposes the uniformity of nature β that natural laws observed now also held in the past and will hold in the future.
Question 3: A historian argues that all historical accounts are inevitably biased. The strongest TOK response to this challenge is:
- Acknowledging perspectival limitations while still recognizing that some accounts are better evidenced than others (Correct answer)
- Concluding that no historical knowledge is possible
- Claiming that only eyewitness accounts can be trusted
- Arguing that bias can be completely eliminated through rigorous training
Correct answer: Acknowledging perspectival limitations while still recognizing that some accounts are better evidenced than others
TOK encourages nuance: bias is real, but accounts can still be evaluated by their evidence, methodology, and corroboration.
Question 4: The concept of 'disinterestedness' in the Natural Sciences refers to scientists:
- Having no financial interest in any research outcome
- Pursuing knowledge for its own sake, free from personal or political agendas (Correct answer)
- Refusing to collaborate with researchers from rival institutions
- Publishing only negative results to avoid publication bias
Correct answer: Pursuing knowledge for its own sake, free from personal or political agendas
Disinterestedness, as a scientific norm (Merton), means researchers should seek knowledge objectively without letting personal motives distort findings.
Question 5: In the TOK framework, which of the following best describes an 'ad hominem' fallacy that can undermine knowledge claims?
- Accepting a claim because it has been published in a peer-reviewed journal
- Dismissing a claim by attacking the character of the person making it rather than addressing the argument (Correct answer)
- Accepting a claim because most experts in the field agree with it
- Rejecting a claim because it contradicts personal intuition
Correct answer: Dismissing a claim by attacking the character of the person making it rather than addressing the argument
Ad hominem fallacies redirect attention from the argument to the arguer, which is a failure of reasoning that weakens knowledge production.
Question 6: Which statement best captures the TOK distinction between 'knowledge' and 'belief'?
- Belief requires evidence; knowledge does not
- Knowledge requires justification and truth in addition to belief, whereas belief requires neither (Correct answer)
- Knowledge and belief are identical β knowing something just means strongly believing it
- Beliefs are public; knowledge is always private
Correct answer: Knowledge requires justification and truth in addition to belief, whereas belief requires neither
The traditional JTB account holds that knowledge is justified true belief, adding two conditions that mere belief alone does not require.
Question 7: A TOK student claims that Indigenous knowledge systems about ecology should be considered legitimate knowledge alongside Western scientific ecology. Which TOK concept best supports this position?
- The view that only falsifiable claims constitute knowledge
- The recognition that different knowledge frameworks can offer valid and complementary perspectives (Correct answer)
- The argument that majority consensus determines knowledge validity
- The principle that all knowledge must be expressible in mathematical form
Correct answer: The recognition that different knowledge frameworks can offer valid and complementary perspectives
TOK acknowledges multiple ways of knowing and frameworks, recognizing that Indigenous and Western ecological knowledge can each offer genuine insights.
