This module focuses on decision-making, heuristics, biases, forecasting, and nudging. You’ll learn how people make judgments, the errors they tend to make, and how psychological insights can improve decision-making.
🔹 The Decision Process
• Four Phases of Decision-Making (Shoemaker, 2018)
1. Intelligence – Recognizing the need for a decision.
2. Design – Generating and evaluating alternatives.
3. Choice – Selecting an option.
4. Implementation – Executing the decision.
• Good decision outcomes come from good decision processes (not just luck).
• Example: A company evaluating whether to expand internationally would go through these four phases systematically.
🔹 Overconfidence
• Three Types of Overconfidence:
1. Misprecision – Thinking you’re more precise than you are.
2. Misestimation – Overestimating or underestimating outcomes.
3. Misplacement – Believing you’re better than others.
• More information often increases overconfidence, rather than improving accuracy.
• Example: A student believes they aced a test but later finds they misunderstood key concepts.
🔹 Dual-System Thinking
• System 1 (Intuitive) – Fast, automatic, emotional.
• System 2 (Reflective) – Slow, deliberate, logical.
• Example: You instinctively think a luxury car must be better (System 1), but after research, you find a cheaper option with similar specs (System 2).
🔹 Major Heuristics & Biases
🔹 Nudging
• Definition: Subtle interventions that steer people toward better decisions without restricting choices (Thaler & Sunstein, 2021).
• Example: Automatically enrolling employees in a 401(k) plan but allowing them to opt out.
• Types of Nudges:
1. Defaults – Making the best choice the automatic option.
2. Framing – Presenting information in a way that influences decisions.
3. Salience – Highlighting important details to attract attention.
• Example: Labeling unhealthy foods in red and healthy foods in green influences better eating choices.
🔹 Why Are We Bad at Forecasting?
• Overconfidence Bias – We trust our predictions too much.
• Hindsight Bias – We believe past events were more predictable than they were.
• Affective Forecasting (Gilbert, 2006) – We overestimate how future events will impact our happiness.
• Example: People expect a job promotion to make them much happier, but over time, their happiness returns to baseline.
• How to Improve Forecasting:
1. Start from the outside view – Look at historical data.
2. Use probability estimates rather than gut feelings.
3. Learn from superforecasters – They continuously update their beliefs based on new evidence.
1. A person believes plane crashes happen frequently because they saw recent news reports about them. This is an example of:
A) Representativeness heuristic
B) Availability heuristic
C) Regression fallacy
D) Confirmation bias
2. A baseball player has an amazing rookie season but performs worse the next year. The best explanation is:
A) Overconfidence bias
B) Regression to the mean
C) The Affect Heuristic
D) Anchoring effect
3. People tend to donate more when they see a picture of a single starving child rather than statistics about millions suffering. This is called:
A) Hindsight bias
B) Base rate neglect
C) Identifiable victim effect
D) Attribute substitution
4. A company wants more employees to enroll in its 401(k) plan. The best nudge they could use is:
A) Framing retirement benefits in a positive light
B) Making enrollment automatic with an opt-out option
C) Offering financial incentives for enrollment
D) Providing employees with extensive financial education
5. A politician claims they knew all along that a law would fail, even though they originally supported it. This is an example of:
A) Overconfidence bias
B) Hindsight bias
C) The mere exposure effect
D) The availability heuristic
1. (B) Availability heuristic – The person judges probability based on how easily examples come to mind.
2. (B) Regression to the mean – Extreme performance naturally tends to move back toward the average.
3. (C) Identifiable victim effect – People respond emotionally to a single, known individual more than to large groups.
4. (B) Making enrollment automatic with an opt-out option – This default nudge increases participation.
5. (B) Hindsight bias – The person falsely believes they always knew the outcome.
✅ Use Active Recall – Quiz yourself using flashcards or practice questions.
✅ Apply Concepts to Real Life – Think of how heuristics & biases affect everyday decisions.
✅ Practice Questions – Revisit tricky concepts by answering questions without looking at notes.
✅ Teach a Friend – Explaining concepts aloud reinforces understanding.
