You'll turn the core framework of *Thinking, Fast and Slow*—the division, conflict, and typical biases of System 1 and System 2—into a mini-lesson that can be delivered in 10 minutes, including 2 interactive experiments and 4 high-frequency bias examples, ready to share with your team, students, clients, or family.

Final work

A *System 1 & System 2 Mini-Lesson Script* (opening interaction + concrete explanation of the two systems + 4 bias slices + live experiment + one takeaway tool)

Estimated time

1–1.5 hr

Your final work

Purpose:Help the audience understand the division between fast and slow thinking in 10 minutes, see how their own thinking can go wrong, and walk away with a cognitive tool they can use tonight.

Parts:

  • Opening interactive experiment (1–2, letting the audience trigger System 1 firsthand)
  • Concrete explanation of the two systems (using metaphors + everyday examples, no book list)
  • 4 high-frequency bias case slices (one each for anchoring / availability / loss aversion / framing effect)
  • Bias interactive Q&A (let the audience guess which trap they just fell into)
  • Closing tool: 'One question to slow down' (something they can take and use immediately)
  • Who you're speaking to + what the audience can do afterward (tailored to your specific scenario)

Use cases:

  • · For your team: help colleagues spot intuition traps before high-stakes decisions
  • · For students / book clubs: clarify the book's core framework and invite deeper reading
  • · Record as a video: use as a script for a short video or podcast episode
  • · For clients / sales: explain why certain decisions are easily anchored, building trust
  • · For kids / family: use everyday stories to help loved ones understand the limits of intuition

Opening Interactive Experiment (Line Comparison / Bat and Ball)

Let the audience trigger System 1 firsthand before speaking, then have System 2 correct them, directly experiencing the switch between the two systems.

How to use it here:

At the start of the script, ask the audience 'A bat costs $1 more than a ball. How much is the ball?' or 'Estimate the length of these two lines.' After they give their intuitive answer, reveal the correct answer and use this 'aha moment' to introduce System 1 vs. System 2. More convincing than any slide definition.

Boundaries:

The experiment is only for demonstrating the limits of intuition; do not use it to mock or judge any participant's intelligence.

Concrete Explanation of the Two Systems (Fast Brain vs. Slow Brain / Autopilot vs. Manual Driving)

Use everyday metaphors to make abstract concepts tangible: System 1 is autopilot (fast, effortless, handles 95% of decisions), System 2 is manual driving (slow, effortful, handles a few high-stakes judgments).

How to use it here:

Instead of copying academic definitions, translate Kahneman's framework into the audience's language. List what System 1 is good at (recognizing faces, driving, emotional reactions) and what System 2 is good at (math, unfamiliar languages, complex decisions), and let the audience categorize 'which decisions today were on autopilot.'

Boundaries:

Avoid making the audience think System 1 is the 'bad brain'—it's efficient and accurate in most situations, only prone to errors in high-stakes decisions.

4 High-Frequency Bias Case Slices

Anchoring / Availability / Loss Aversion / Framing Effect, each bias with one everyday scenario + one data experiment, delivered within 90 seconds.

How to use it here:

Anchoring: How e-commerce strikethrough prices manipulate your perception of a 'fair price' (reference Kahneman's random wheel anchoring experiment). Availability: Why you fear plane crashes more than the actual risk (emotional intensity of recent news ≠ true probability). Loss Aversion: Why losing $1000 hurts twice as much as gaining $1000 feels good (prospect theory). Framing Effect: '90% survival rate' vs. '10% mortality rate' describe the same surgery, but your feelings are completely different.

Boundaries:

Each bias case must be accompanied by real or realistic data/experiment sources; do not exaggerate numbers.

Interactive Bias Guessing (Audience Participation Segment)

After each bias or midway through the script, present a scenario and ask the audience to guess 'which bias is this?' turning the explanation into an interactive game.

How to use it here:

Design 2–3 mini-scenarios like 'Guess which mistake I made' (e.g., 'A friend just had a car accident, and suddenly you think driving is dangerous—is this availability bias or framing effect?'), let the audience discuss for 30 seconds, then reveal the answer. Suitable for team training, book clubs, classrooms, etc.; for videos, you can use on-screen 'bullet comments' to guide.

Boundaries:

Ensure the scenarios have clear answers; avoid ambiguous cases where 'both biases could apply'—that confuses rather than benefits the audience.

Closing 'Use Tonight' Tool: One Question to Slow Down

End the script with a tool the audience can use immediately—before making any decision involving >$500 or affecting >1 month, ask themselves a System 2 triggering question.

How to use it here:

Example closing tool: 'Before you hit confirm, ask yourself: Am I responding to a real need, or to a price tag / urgency / others' choices?' Have the audience save this sentence in their phone notes as a post-lesson action. This is the key design that transforms the script from 'I learned a principle' to 'I can change one thing today.'

Boundaries:

The tool must be simple enough for the audience to memorize immediately; do not design complex processes that require looking up tables or internet access.

Work rules

Your work MUST include

  • Must have a clear 'who you're speaking to' (audience scenario)
  • Must include at least 1 opening interactive experiment (let the audience trigger System 1 firsthand)
  • Must use metaphors or stories to explain the two systems, not read definitions from the book
  • Must cover at least 3 of the 4 high-frequency biases (anchoring / availability / loss aversion / framing effect)
  • Each bias must be paired with a real-life scenario close to the audience's experience
  • Must have a closing 'takeaway tool' (a slow-thinking question or action they can use immediately)
  • The entire script must be deliverable in 10 minutes (excluding Q&A)

Your work CANNOT just be

  • Cannot be a chapter summary or content digest of the book
  • Cannot copy academic definitions from the book without transformation
  • Cannot be all theory with no audience participation or interaction design
  • Cannot list all biases flatly—must have a story arc and rhythm
  • Cannot leave the audience with only 'knowing a term' and no actionable tool

AI can help you here

Round 1: Help me define the audience and structure of the script

When to use: You know who you want to speak to, but aren't sure which framework, which cases, or how to allocate the 10 minutes.

I'm using the book '{{book title}}' to complete the '{{route name}}' project.

Please help me design a script structure that fits my situation.

My audience and scenario:
[Describe who you're speaking to, the occasion, approximate number of people, and their familiarity with behavioral economics]

How long I plan to speak:
[Fill in time, e.g., 10 min / 15 min / half hour]

Please output:
1. Suggested script structure (time per segment + core task)
2. Best opening interactive experiment for this audience (1–2 options)
3. Which 3 biases to focus on (anchoring / availability / loss aversion / framing effect, recommended for my audience)
4. Closing tool suggestion (1 question or action they can use immediately)
5. 1–2 questions this audience is most likely to ask, with brief answer ideas

Yellow placeholders need you to fill in before using the AI.

AI can help you organize ideas, but cannot make final judgments for you. Don't let AI fabricate experiences, cases, or misleading content.

Round 2: Help me write the explanation paragraph for a specific bias

When to use: You already have the script structure and want to make a bias explanation paragraph more vivid and persuasive.

I'm using the book '{{book title}}' to complete the '{{route name}}' project, preparing a 10-minute script.

My audience is: {{topic}}

I need help with the explanation paragraph for the '{{topic}}' bias.

Please write a 90-second script paragraph for this bias, including:
1. A hook opening (making the audience feel 'wait, this is about me')
2. A scenario close to this audience's daily life to explain the bias
3. An optional interactive question (30 seconds)
4. A one-sentence summary (so the audience can repeat it)

Note:
- Don't copy academic language from the book
- Use realistic cases, don't exaggerate numbers
- Keep the tone conversational, like talking to someone, not reading a paper

Yellow placeholders need you to fill in before using the AI.

AI can help you organize ideas, but cannot make final judgments for you. Don't let AI fabricate experiences, cases, or misleading content.

Round 3: Help me review the complete script

When to use: You've finished the full script or outline and want to check pacing, content, and feasibility before a trial run.

I'm submitting a project work on Shufang Island.

Book: '{{book title}}'
Project route: {{route name}}
My audience scenario: {{topic}}

My complete script (or segmented outline):
{{draft}}

Please check against the following criteria:
1. Can the overall pacing stay within the allotted time (based on my time markings)?
2. Does the opening interaction truly let the audience trigger System 1 (not just 'tell' them the definition)?
3. Is the explanation of the two systems clear and free of academic jargon?
4. Are the bias cases close to the audience's life, with data or experimental support?
5. Is the closing tool simple enough for the audience to remember and use immediately?
6. Is there a risk of 'only explaining principles without prompting action'?
7. Is there any risk of exaggeration, fabrication, or misinformation?

Please output:
- Overall assessment (ready to deliver / needs adjustment / needs rewrite)
- What's done well
- What must be changed
- What could be enhanced
- One tip for preparing the trial run
