Understanding Cognitive Biases: Part 2

Unit 1 · Lesson 1.7 · Last updated November 3, 2026

A 45-minute lesson in which students become experts on one bias through a jigsaw: present bias, overconfidence bias, the anchoring effect, or loss aversion. They then share what they learned in groups of 4 and synthesize how all four biases can distract from the principles of economic thinking in personal finance decisions.

Overview

In this lesson, students build on their prior learning about cognitive biases. Through a jigsaw activity, they investigate how four specific biases, which are present bias, overconfidence bias, the anchoring effect, and loss aversion, can undermine effective application of economic thinking in personal financial choices. Note: this lesson assumes students were introduced to cognitive biases in Lesson 1.6.


Learning Objectives

  • Explain how cognitive biases influence financial decision making.
  • Identify strategies for avoiding cognitive biases.

Slides 2–4

  1. Display Slide 2. Place students into pairs, or groups of 3 if needed, and allow 1 minute to consider the prompts on the slide. Note: additional educator tips, details, and suggested answers are in the notes section throughout the Instruction Slides.
  2. Advance to Slide 3. Use the text on the slide to preview the task students will complete when they receive the Student Handout in the next step.
  3. Distribute 1 copy of the Student Handout to each student. Direct pairs to pick the two scenarios they are most interested in, or assign scenarios, and complete the instructions on Slide 3. Allow approximately 4 minutes, circulating to answer questions and offer clarification, and reference the Suggested Responses as needed.
  4. Call on students to quickly debrief each of the scenarios. Click to reveal the remaining text on the slide and tell students they will learn more about how to avoid cognitive biases in this lesson.
  5. Proceed to Slide 4. Explain the learning objectives for students.

Slides 5–13

  1. Progress through Slides 5–7. Point out that cognitive biases can complicate consequential financial decisions, and emphasize the role the principles of economic thinking play in making decisions aligned with an individual's preferences and goals.
  2. Display Slide 8. Organize students into groups of 4, or groups of 3 as needed, and tell students they will be responsible for learning more about one of the cognitive biases. Note: the overconfidence and loss aversion readings are best suited for students struggling with the unit or with reading comprehension, and the anchoring effect reading is best suited for students confident in the material and with relatively high reading comprehension.
  3. Proceed to Slide 9. Draw students' attention to the Deeper Dive Into Cognitive Biases portion of the Student Handout and explain that students will respond to the prompts on the slide in the relevant quadrant of their handout.
  4. Reinforce that students will read their text independently and will be responsible for presenting that information to their group later in the lesson.
  5. Distribute 1 set of Cognitive Biases Readings to each group and allow students to select their reading, or assign readings. Note: make all readings accessible on your learning management system and encourage interested students to read the other articles.
  6. Allow students approximately 12 minutes to read their selected text and answer the two prompts in the space provided on the Student Handout. Circulate while students work to answer questions and offer clarification, and reference the Suggested Responses for sample answers.
  7. Display Slide 10. Tell students they will now briefly leave their group to confer with peers who analyzed the same reading. Assign an area of your classroom to each reading and announce those locations, reminding students that this is their opportunity to gain clarity before presenting to their group.
  8. Allow expert groups approximately 2 minutes to review their responses to the prompts and obtain clarification, then direct students to return to their original group.
  9. Advance to Slide 11 and review the instructions. Tell students that after all group members share, they will synthesize the information from the readings to answer a question in the center box, and allow groups approximately 10 minutes. Note: emphasize that the focus should be on listening to their group mates and adding general notes, rather than copying down everything students wrote during the individual work time.
  10. Proceed to Slide 12. Direct students to follow the instructions on the slide and record their responses in the central box on the Student Handout, then ask several students to share with the class. Note: students do not need to reach a consensus about connections to the principles of economic thinking, since all four principles could reasonably be connected to each reading, but they should discuss the prompt.
  11. Progress to Slide 13. Direct students to return to their scenarios from the activator and add new tips for avoiding the cognitive biases relevant to their two scenarios, then call on several students to share. See the Suggested Responses.

Slides 14–16

  1. Advance through Slides 14–15. Instruct students to locate their copy of the Unit 1 Overview, distributed in Lesson 1.3, and discuss the prompt with a peer.
  2. Display Slide 16. Direct students to complete the instructions on the slide and remind them that the Unit 1 summative assessment in Lesson 1.10 will gauge their proficiency in the learning objectives on the Unit 1 Overview.

What Educators Are Saying

Hands-on lessons are a priority for me. I am able to find a lot of lessons on the Econiful website, and they are really good and well thought out.

What impressed me most was that I never felt like I was navigating the course alone. Throughout the year, it genuinely felt like I had a full support team alongside me.
