Arguments & implications (DP IB Theory of Knowledge): Revision Note

Building arguments & counterarguments

• An argument in ToK answers the prescribed title by giving reasons for a judgment about the title’s key concept

• A ToK argument stays focused on knowledge, meaning that it explains how knowledge is produced, verified, shared or challenged, rather than describing topic content

  • E.g. instead of describing what a vaccine is, you focus on how clinical trials, replication, and peer review affect confidence in the claim that a vaccine is safe and effective

• A point becomes an argument when it includes:

  • a clear claim: e.g. replication makes knowledge more reliable

  • justification: e.g. independent repeats can reveal random error or biased sampling, so agreement is less likely to be a coincidence

  • a link back to the title: e.g. this matters because it explains why reliability is stronger when claims can be checked in this way

Developing clear claims that are linked to the title

• Clear claims answer the prescribed title by saying something specific about the key concept in the title

  • E.g. if a key concept is reliability, a clear claim is that “reliability increases when methods allow independent checking”

• A linked claim explains how it is connected to the title, e.g.:

  • unlinked: replication can reveal errors in an experiment

  • linked: replication can reveal errors in an experiment, so the title’s claim about reliability is more convincing when knowledge can be independently replicated is supported

• Clear links to the prescribed title are important because they show the examiner exactly how each claim supports your exploration of the title, rather than leaving your reasoning to be inferred

Introducing counterclaims

• A counterclaim is a challenge to your main claim that creates a different answer to the prescribed title

  • A counterclaim matters because the prescribed title is asking for a judgment, and judgments are stronger when you show what could undermine your position

• Strong counterclaims target the reason behind your claim, meaning that they explain why your justification might not support the first conclusion you drew about the key concept, e.g.:

  • claim: replication increases reliability, so the title’s claim about reliability is convincing

  • counterclaim: replication can reproduce the same flawed assumption or method, so reliability can still be overstated even when results are repeated

• A useful counterclaim changes what you can say about the title because it forces you to add a limit, exception or condition to your answer

• After giving a counterclaim, you should evaluate which view is stronger; this allows you to provide a judgment, not just a list of views

Maintaining balance between different arguments

• Balance means treating more than one argument as reasonable

  • Balance matters because the prescribed title is asking for a judgment, and a judgment is more convincing when you show that you have tested it against alternatives

• Balance does not mean giving equal weight to every view, because some positions will be stronger once you consider the evidence.

• A balanced conclusion works when it states what you accept, what you reject and the conditions under which your judgment would change

Considering implications

• Implications are what your claim suggests about knowledge, i.e., what follows if your claim about the title’s key concept is true

• Implications show why your point matters

• Each argument should lead to an implication about the key concepts in the title

• A clear implication often answers a “so what?” question, because it shows how your point changes our understanding of the issues raised in the title

  • E.g. if your claim is that reliability increases with independent checking, the implication is that a claim is stronger in contexts where checking is possible and weaker where it is not

• Implications can also reveal assumptions in the title, because your argument may only work if a hidden assumption is accepted

  • E.g. an argument about reliability may assume equal access to correctly functioning tools for measuring a variable accurately

• Showing why the discussion matters means explaining why this point is necessary for exploring the prescribed title

• A strong “why it matters” line states what the paragraph adds to your exploration of the title, such as support for your main claim or a serious challenge

Writing a strong conclusion

• A strong conclusion answers the prescribed title directly by giving your final judgment on the title’s key concept

  • A conclusion merely summarises when it repeats your main points, but does not state your final answer to the prescribed title

• Your final lines should show how your thinking has developed, i.e., you state what you now think after testing different arguments and counterarguments

• You should make your judgment specific by stating the conditions under which your answer is more convincing and the conditions under which it is less convincing
