Bias Detector Teacher Lesson Guide

Teacher lesson guide target: Use this page for lesson planning, classroom setup, curriculum alignment, common mistakes, and related resources for Bias Detector. The playable game is /games/bias-detector.

Bias Detector turns behavioral economics into short scenarios. Read the situation, identify the bias, and see how anchoring, loss aversion, framing, and confirmation bias distort choices.

Lesson objective

Students should finish the activity able to explain the economic decision rule behind the game, describe at least one missed prompt, and connect the result to a graph, data point, incentive, or policy choice.

Classroom setup

Use Bias Detector before behavioral economics examples. Have students name the bias and rewrite the choice in neutral language.

Concepts and curriculum alignment

Key concepts covered: cognitive biases, behavioral economics, anchoring, loss aversion. AP Micro Unit 1: Basic Economic Concepts; AP Micro Unit 5: Market Failure and Role of Government; IB Microeconomics: Behavioral economics; IB Microeconomics: Consumer choice

Practice Path

  1. Review behavioral economics
  2. Review anchoring bias
  3. Play Prisoner's Dilemma

Common Mistakes

  • Memorizing bias labels without explaining the decision pattern behind the mistake.
  • Calling every bad choice irrational instead of identifying the incentive or information shortcut.
  • Missing how framing changes perceived costs even when the underlying payoff is the same.

Teacher debrief prompt

Ask students: Which clue changed your answer, what economics rule explains the change, and what would you do differently on a rematch?
