IB DP Core: Theory of Knowledge 5

Question 1

In TOK, the 'coherence theory of truth' holds that a statement is true if:

Accepted Answer

It fits coherently within a larger system of mutually consistent beliefs

Answer

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?

Accepted Answer

The assumption that nature is uniform and its laws apply consistently across time and space

Answer

Science presupposes the uniformity of nature — 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:

Accepted Answer

Acknowledging perspectival limitations while still recognizing that some accounts are better evidenced than others

Answer

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:

Accepted Answer

Pursuing knowledge for its own sake, free from personal or political agendas

Answer

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?

Accepted Answer

Dismissing a claim by attacking the character of the person making it rather than addressing the argument

Answer

Ad hominem fallacies redirect attention from the argument to the arguer, which is a failure of reasoning that weakens knowledge production.
