Critical Thinking: Avoiding Cognitive Biases

Active learning helps students recognise their own cognitive biases by making them visible in real situations rather than abstract discussions. For topics like this, where students may believe they are already rational thinkers, concrete examples from media or personal beliefs create moments of genuine surprise and insight.

Group Hunt: Bias Examples in Media

Divide students into small groups and provide news articles or social media clips. Groups identify at least two cognitive biases, note their effects, and suggest mitigation strategies. Each group shares one example with the class for discussion.

Analyze how cognitive biases can distort rational judgment.

Facilitation Tip

During Group Hunt, ask each group to present one media example where multiple biases appear, so students see how biases often overlap in real examples.

What to look for

Present students with a short, controversial opinion piece. Ask: 'What specific cognitive biases might be at play in this author's argument? How could someone reading this article actively counteract those biases to think more critically about the claims?'

Pairs Role-Play: Confirmation Bias Debate

Pairs receive a philosophical claim, like 'Free will does not exist.' One argues with bias, the other counters using strategies like devil's advocate. Switch roles after 5 minutes and debrief on observed biases.

Design strategies to minimize the impact of personal biases in philosophical analysis.

Facilitation Tip

In Pairs Role-Play, remind students to switch sides mid-debate to experience how confirmation bias feels from both perspectives.

What to look for

Provide students with two brief, opposing arguments on a philosophical topic. Ask them to write one sentence identifying which argument might be more susceptible to confirmation bias and why, and one sentence suggesting how they would 'steelman' the weaker argument.

Whole Class: Structured Debate with Checklist

Split class into two teams on a topic like 'Is morality objective?' Provide a bias checklist for speakers to self-assess. Moderator notes biases; class votes on clearest arguments post-debate.

Evaluate the challenge of achieving objectivity in human thought.

Facilitation Tip

For the Whole Class Debate, provide a checklist of biases to refer to during speeches so students actively look for them in their opponents’ arguments.

What to look for

Students bring an example of a belief they hold strongly. In pairs, they explain their belief and then coach their partner to identify potential biases supporting it. The partner then suggests one counter-argument or piece of evidence that challenges the belief, which the original student must acknowledge.

• 20 min · Individual

Individual: Bias Reflection Journal

Students journal a personal decision influenced by bias, identify the type, and rewrite it objectively. Share anonymously in a class gallery walk for peer insights.

Analyze how cognitive biases can distort rational judgment.

Facilitation Tip

Have students keep their Bias Reflection Journals open during discussions to capture immediate thoughts before biases fade from memory.

What to look for

Present students with a short, controversial opinion piece. Ask: 'What specific cognitive biases might be at play in this author's argument? How could someone reading this article actively counteract those biases to think more critically about the claims?'

A few notes on teaching this unit

Experienced teachers approach this topic by starting with familiar examples before moving to abstract concepts, as students learn better when biases are tied to content they already engage with. It’s important to model your own struggles with bias, so students feel safe identifying their own. Research shows that structured self-reflection, like journaling, works better than lectures for long-term bias recognition.

Students will confidently point out biases in arguments and suggest strategies to reduce their influence. They will also demonstrate self-awareness by reflecting on how their own thinking might be affected by these biases during discussions and debates.

Watch Out for These Misconceptions

• During Group Hunt: Bias Examples in Media, some students may believe cognitive biases affect only uneducated people.

  During Group Hunt, ask each group to explain how even experts in their chosen media example might have fallen prey to biases, using the media personalities or creators as examples. This helps students see that bias is universal when they analyse familiar figures.

• During Pairs Role-Play: Confirmation Bias Debate, students may think biases cannot be overcome with effort.

  During Pairs Role-Play, have each student deliberately argue against their own belief first, then switch sides again to argue for it while consciously avoiding confirmation bias. This shows them that effortful perspective-taking can weaken bias effects.

• During Whole Class: Structured Debate with Checklist, students may assume philosophy is free from cognitive biases.

  During Whole Class Debate, ask students to refer to the checklist and point out moments when anchoring on first ideas or other biases appear in philosophical arguments. This makes hidden assumptions visible and shows how even philosophers are not immune.
