Reflection & Metacognition (DP IB Theory of Knowledge): Revision Note

Reflection & metacognition

• Reflection is the habit of pausing to think about what you believe, why you believe it, and whether your reasons are strong enough

  • This should help you to spot weak reasoning or untested assumptions before you treat a belief as knowledge

• Reflecting on knowledge can include:

  • identifying biases

  • evaluating evidence

  • examining beliefs

Identifying biases

• Bias is a systematic tendency to think in a certain way; this can distort judgment even when you are trying to be fair or rational

• Common sources of bias include:

  • confirmation bias: noticing and trusting information that supports what you already think

  • availability bias: overestimating the importance of what is common because examples are easy to recall

  • authority bias: giving extra weight to claims because an expert or institution said them

  • in-group bias: trusting “people like us” more than outsiders

• Identifying bias within your thinking does not mean your conclusion is automatically wrong, but it does mean you should check whether the claim still holds when you rely on evidence and reasoning

Evaluating evidence quality

• Evidence quality is stronger when the source is credible, the reasoning is clear and the claim can be checked against other sources

• Useful evidence quality checks include:

  • relevance: whether the evidence actually supports the specific claim being made

  • reliability: whether the method used would give similar results if repeated 

  • corroboration: whether independent sources support the same conclusion

  • bias/conflicts of interest: whether incentives or selective reporting could have skewed findings

Comparing beliefs with alternatives

• It can be a good idea to compare beliefs that you hold with alternative ideas

• Ways to do this include:

  • asking what someone who disagrees would say, and why

  • looking for counterexamples that challenge your belief

  • checking how your belief changes across contexts, e.g. different cultures, disciplines or time periods

• Comparing beliefs with alternatives allows you to check whether your belief is supported by evidence, rather than being based on hidden assumptions or preferences.

Metacognition: Knowledge about your own knowing

• Knowing how we know something involves metacognition, i.e. “thinking about your thinking”

• Metacognition involves:

  • awareness of your own thinking processes, e.g. noticing whether you are relying on memory, emotion, intuition or reasoning

  • monitoring your understanding and confidence, e.g. checking what you know and what you are unsure about

  • regulating your thinking, e.g. seeking more evidence or asking for feedback

  • reflecting on and learning from errors, e.g. updating your approach when you realise you were mistaken

• Knowing how you know something helps you become a more responsible knower because you can check your claim, communicate uncertainty honestly and avoid passing on ideas that are not well supported
