About This MicroSim

A scenario-based self-diagnostic allows students to move from abstract knowledge of bias to personal recognition of bias in their own reasoning. Testing against confirmation bias, anchoring, groupthink, authority bias, and more, the simulation creates a finalized metacognitive "bias profile" radar chart.

Lesson Plan

Grade Level

9-12 (High School / IB TOK)

Duration

20-25 minutes

Prerequisites

  • Familiarity with the definitions of at least 4 common cognitive biases (Confirmation Bias, Anchoring, Dunning-Kruger, Hindsight).

Learning Objectives

  • Assess your own susceptibility to cognitive biases by responding to realistic scenarios and reflecting on which biases were activated.

Activities

  1. Exploration (10 min): Allow students to play through the 8 scenarios independently. Remind them to answer honestly based on their first instinct, rather than trying to "game" the system to appear perfectly rational. Let them review their final radar chart.
  2. Guided Practice (5 min): Pick one scenario as a class (e.g., Scenario 2: Estimating a fair price after seeing an inflated price tag). Review the feedback panel and discuss how "Anchoring" manipulates our baseline data processing, making us prone to marketing tricks.
  3. Assessment (10 min): Have students review their individual "Bias Profile" radar chart. Ask them to write a reflection paragraph identifying their largest "spike" (the bias they are most susceptible to) and devise one actionable strategy they can use to counteract it.

Assessment

  • Completion of the 8 diagnostic scenarios.
  • The insightfulness and practicality of the strategy devised in their concluding reflection paragraph.

Quiz

Test your understanding of cognitive biases with this review question.

1. In the diagnostic tool, if a student consistently chooses answers that defend their original choice even after learning it had negative consequences, they are most likely exhibiting a vulnerability to:

  1. Cognitive dissonance reduction
  2. The Dunning-Kruger effect
  3. Anchoring bias
  4. Hindsight bias
Show Answer

The correct answer is A. When an individual takes an action that contradicts their self-perception as a smart/rational person (e.g., making a bad choice), it creates psychological stress known as cognitive dissonance. To reduce this stress without admitting error, people often irrationally defend the poor choice or twist the facts to justify it.
