Behavioural Economics: Nudges and Choice Architecture

Active learning works well here because nudges and choice architecture are abstract concepts that come to life through first-hand experience. When students simulate real-world decisions like pension defaults or cafeteria layouts, cognitive biases stop being theory and start being observable behaviour. This hands-on approach builds durable understanding and connects classroom ideas to everyday choices students already face.

Activity 01

• Simulation Game
• 35 min · Pairs

Simulation Game: Pension Nudge Defaults

Pairs receive mock enrolment forms with varying defaults (opt-in vs opt-out). They complete choices under time pressure, then switch roles and discuss how defaults swayed decisions. Groups report findings to class for comparison.

Explain how 'nudges' can influence consumer behavior without restricting choice.

Facilitation Tip

During the Pension Nudge Defaults simulation, circulate with a timer and ask each group to verbalize their first instinct before seeing the default option, so they notice how defaults exploit status quo bias.

What to look for

Present students with a scenario: A local council wants to increase recycling rates. Ask them: 'What are two cognitive biases that might prevent people from recycling? How could you design a 'nudge' or adjust the choice architecture to encourage more recycling, and what are the ethical considerations of your proposed intervention?'

Activity 02

• Formal Debate
• 45 min · Small Groups

Formal Debate: Nudge Ethics in Policy

Divide class into teams to argue for or against government nudges like automatic tax withholding. Provide evidence packs beforehand. Hold structured debate with rebuttals, followed by whole-class vote on positions.

Analyze the ethical considerations of using behavioral insights in public policy.

Facilitation Tip

For the Nudge Ethics Debate, assign roles randomly and require speakers to cite at least one BIT trial from the Data Dive to ground their arguments.

What to look for

Provide students with a short case study of a government nudge policy (e.g., energy saving prompts). Ask them to identify: 1. The market failure being addressed. 2. The specific nudge used. 3. The cognitive bias it aims to exploit. 4. One potential ethical concern.

Activity 03

• Inquiry Circle
• 40 min · Small Groups

Redesign: Cafeteria Choice Architecture

Small groups redesign a school canteen layout to nudge healthy eating, using photos and props. Predict behaviour changes, present designs, and class votes on most effective nudge with justifications.

Evaluate the effectiveness of choice architecture in promoting desired outcomes.

Facilitation Tip

When students redesign the Cafeteria Choice Architecture, provide sticky notes in only three colours to limit options and force prioritisation, mirroring real-world design constraints.

What to look for

Students individually write a brief proposal for a nudge to address a specific public health issue (e.g., reducing sugar consumption). They then exchange proposals with a partner. Each partner evaluates the proposal based on: clarity of the nudge, identification of the relevant bias, and a brief assessment of its ethical soundness, providing one suggestion for improvement.

Activity 04

• 30 min · Individual

Data Dive: BIT Trial Analysis

Individuals review Behavioural Insights Team case studies on energy nudges. Note metrics like savings achieved, then pair to evaluate strengths and limitations before sharing with class.

Explain how 'nudges' can influence consumer behavior without restricting choice.

Facilitation Tip

In the Data Dive, have students graph BIT trial results on mini whiteboards before discussing, so they see variance across populations before jumping to conclusions.

A few notes on teaching this unit

Start by teaching the core biases with short, relatable examples—like why people choose the middle option on a menu or ignore pension opt-in forms. Use the rule of three: introduce a bias, show a nudge that targets it, then immediately ask students to generate their own nudge in pairs. Avoid over-theorising; let students discover the power (and limits) of nudges through iteration and reflection. Research shows that active, iterative design tasks build both conceptual clarity and ethical sensitivity faster than lectures or readings alone.

By the end of these activities, students will confidently explain how nudges preserve choice while guiding behaviour, evaluate their ethical trade-offs, and redesign choice environments with evidence. They will move from passively receiving information to actively testing ideas, articulating biases they once overlooked, and justifying their own nudges with data and reasoning.

Watch Out for These Misconceptions

• During the Simulation: Pension Nudge Defaults, watch for students claiming that nudges take away choice because opting out feels hard.

  Use the activity’s reflection sheet to prompt groups to list all the options still available and time how long it takes to opt out, making the trade-off between effort and freedom explicit.

• During the Debate: Nudge Ethics in Policy, watch for students asserting that nudges are always manipulative because they influence behaviour.

  Have each team map their strongest nudge to a cognitive bias and then defend why preserving all options while making one slightly easier aligns with autonomy rather than manipulation.

• During the Redesign: Cafeteria Choice Architecture, watch for students assuming that making healthy foods more visible will work for everyone.

  After redesigns are complete, display BIT trial data on label effectiveness by socio-economic group and ask teams to revise their layouts using the evidence rather than assumptions.
