Behavioral Biases in Economic Decision Making

Active learning helps students move beyond abstract definitions by experiencing behavioral biases firsthand. When students simulate real-world decisions, they see how cognitive shortcuts shape outcomes, bridging the gap between theory and observable behavior.

Activity 01

• Simulation Game
• 45 min · Small Groups

Simulation Game: Herd Behavior Market Game

Divide class into buyers and sellers trading fictional stocks. Introduce planted 'tips' to trigger herd buying or selling. Groups track prices over 5 rounds, then debrief on how following the crowd inflated or crashed values. Students graph results to quantify irrational swings.

Explain how cognitive biases like anchoring and framing affect consumer choices.

Facilitation Tip

During the Herd Behavior Market Game, assign roles explicitly and rotate them so students experience both following and leading the herd.

What to look for

Pose the following to students: 'Imagine you are advising a client who is hesitant to invest. How might you use or counteract the anchoring bias when presenting investment options? Discuss specific phrases or figures you might use or avoid.'

Activity 02

• Inquiry Circle
• 30 min · Pairs

Experiment: Anchoring Estimates

Provide pairs with a high anchor number for estimating UK house prices, then a low one for the same task. Compare group averages and discuss how anchors skewed results. Follow with real data analysis to reveal bias effects.

Analyze the impact of herd behavior on financial market bubbles and crashes.

Facilitation Tip

For the Anchoring Estimates experiment, provide varied anchors (e.g., high, low, random) and require students to justify their final estimates to reveal bias persistence.

What to look for

Present students with two scenarios: Scenario A describes a product with a 10% defect rate, and Scenario B describes a product with a 90% success rate. Ask students to write down which product they would prefer and to explain their choice in terms of framing effects.

Activity 03

• Formal Debate
• 35 min · Small Groups

Formal Debate: Framing Consumer Choices

Present product options framed positively or negatively to small groups. Have them vote and justify choices, then reveal identical options. Whole class votes on rational countermeasures like seeking neutral info.

Differentiate between rational economic behavior and behavior influenced by psychological biases.

Facilitation Tip

In the Framing Consumer Choices debate, assign half the class to argue for one framing and half for the other, then switch sides to deepen perspective-taking.

What to look for

On an exit ticket, ask students to define herd behavior in their own words and provide one example of how it might affect their personal spending habits or investment choices.

Activity 04

• Case Study Analysis
• 40 min · Pairs

Case Study Analysis: Bubble Analysis

In pairs, assign historical cases like the dot-com bubble. Identify biases at play, map decision timelines, and propose behavioral interventions. Share findings in a class gallery walk.

Explain how cognitive biases like anchoring and framing affect consumer choices.

Facilitation Tip

In the Bubble Analysis case study, assign each group a different historical bubble to ensure diverse examples and peer teaching opportunities.

What to look for

A few notes on teaching this unit

Experienced teachers front-load the psychological foundations before activities, using short video clips or real-world headlines to prime students. Avoid over-explaining the bias after the activity; let students articulate their observations first, then refine their understanding through guided questioning. Research shows that self-generated explanations stick longer, so debriefs should focus on student discoveries rather than instructor-led summaries.

Successful learning is visible when students can identify biases in new contexts, explain their mechanisms, and justify interventions to mitigate their effects. Look for students connecting simulations to case studies with evidence-based reasoning.

Watch Out for These Misconceptions

• During the Herd Behavior Market Game, watch for students assuming herd behavior always leads to irrational outcomes.

  Use the debrief to contrast efficient coordination (e.g., forming a line) with destructive herd behavior (e.g., market bubbles). Ask groups to categorize their simulation rounds and justify each.

• During the Anchoring Estimates experiment, watch for students believing anchors only affect novices.

  Have students compare their own estimates with those of peers who received different anchors. Ask them to reflect in journals on how their professional judgments might be swayed by initial data.

• During the Framing Consumer Choices debate, watch for students dismissing framing as mere wordplay with no real impact.

  Use the debate’s rebuttal phase to introduce regulatory examples, like mandatory plain packaging for cigarettes, to show framing’s tangible consequences.
