Behavioural Economics: Nudges and Choice ArchitectureActivities & Teaching Strategies
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.
Learning Objectives
- 1Explain how specific cognitive biases, such as present bias or loss aversion, can lead to suboptimal economic decisions.
- 2Analyze the effectiveness of different 'nudges' in altering consumer behavior, citing empirical evidence.
- 3Evaluate the ethical implications of using choice architecture in public policy, considering potential trade-offs between paternalism and individual autonomy.
- 4Design a hypothetical 'nudge' intervention for a specific market failure, detailing the choice architecture and predicted behavioral impact.

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.
Prepare & details
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.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
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.
Prepare & details
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.
Setup: Two teams facing each other, audience seating for the rest
Materials: Debate proposition card, Research brief for each side, Judging rubric for audience, Timer
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.
Prepare & details
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.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
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.
Prepare & details
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.
Setup: Groups at tables with access to source materials
Materials: Source material collection, Inquiry cycle worksheet, Question generation protocol, Findings presentation template
Teaching This Topic
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.
What to Expect
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.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Simulation: Pension Nudge Defaults, watch for students claiming that nudges take away choice because opting out feels hard.
What to Teach Instead
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.
Common MisconceptionDuring the Debate: Nudge Ethics in Policy, watch for students asserting that nudges are always manipulative because they influence behaviour.
What to Teach Instead
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.
Common MisconceptionDuring the Redesign: Cafeteria Choice Architecture, watch for students assuming that making healthy foods more visible will work for everyone.
What to Teach Instead
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.
Assessment Ideas
After the Debate: Nudge Ethics in Policy, present students with a scenario about a school introducing a nudge to reduce screen time. Ask them to identify two cognitive biases the nudge might target and evaluate its ethical soundness, using arguments and evidence from the debate.
During the Data Dive: BIT Trial Analysis, ask students to individually complete a short table identifying for each trial: the bias targeted, the nudge mechanism, the population, and one contextual factor affecting success, then discuss answers as a class.
After students write their Nudge Proposals for a public health issue, have them exchange proposals and evaluate each other using a two-column sheet: one column for strengths, one for improvements. Collect sheets to check for alignment between identified biases, clarity of nudges, and ethical reasoning.
Extensions & Scaffolding
- Challenge: Ask students to design a nudge for a novel context, such as reducing water use in drought-prone areas, and present it to the class with a short memo explaining the bias, mechanism, and ethics.
- Scaffolding: Provide a partially completed nudge proposal template with sentence starters for students struggling to articulate their design or ethical concerns.
- Deeper exploration: Invite students to compare two BIT trials side-by-side, identifying which contextual factors (population, timing, messaging) explain differences in effectiveness.
Key Vocabulary
| Nudge | A subtle intervention in the choice architecture that alters people's behavior in a predictable way without forbidding any options or significantly changing their economic incentives. |
| Choice Architecture | The context in which people make decisions, including the design of menus, the order of options, and the default settings, which can influence choices. |
| Cognitive Bias | A systematic pattern of deviation from norm or rationality in judgment, often leading individuals to make decisions that are not in their best interest. |
| Libertarian Paternalism | A policy approach that tries to steer people in a beneficial direction while preserving their freedom of choice. |
