Introduction: From “Using” AI to “Thinking” with AI
If you view AI as a “shortcut to quick answers,” all you’ll get are “answers that seem correct.”
However, if you reframe ChatGPT as a “tool for thinking”, the quality of your thinking improves, you’ll regret fewer decisions, and your output will become more consistent. Balancing practicality and philosophy, I’ll summarize specific workflows, question-framing techniques, and tips for avoiding pitfalls to help you become a “person who thinks with AI”.
What You’ll Learn in This Article
- A framework for using ChatGPT as a thinking environment rather than just a “thinking aid”
- How to switch between three thinking modes (divergent, convergent, and structured)
- Five practical use cases (planning, learning, writing, decision-making, and reflection)
- The line between “dependence” and “extension” (responsibility, autonomy, originality)
Why a “Tool for Thinking”?
- There are limits to what a person can achieve with their own mind alone. Memory capacity, diversity of perspectives, and the effects of fatigue.
- ChatGPT is an “externalized drafting desk for the brain.” A place to store hypotheses, a sounding board for questions, and a shelf for arguments.
- You are the one who reaches the conclusion. That is precisely why its design and usability as a tool are so important.
Switching Between the 3 Thinking Modes
1. Diverge
- Purpose: Broadly gather material and expand your perspectives
- How to use:
- “5 angles that are easy to overlook”
- “List opposing views, weaknesses, and risks”
- “How would this compare to other fields?”
2. Converge
- Purpose: Establish evaluation criteria and narrow down candidates
- How to use:
- “List success criteria, constraints, and evaluation standards in bullet points”
- “Briefly outline the trade-offs of the top three proposals”
- “Which proposal is best suited for ‘who I am right now’?”
3. Structure
- Purpose: Visualize key points, procedures, and responsibilities
- How to use:
- “Break down the decision-making process into steps”
- “Organize premises, hypotheses, verification procedures, and decision criteria separately”
- “Create an execution checklist”
Workflow: Hypothesis → Question → Dialogue → Experiment → Documentation
- Hypothesis Notes
- Draft “Current Situation, Challenges, Preliminary Hypothesis, and Expected Outcomes” in 30 seconds.
- Refining the Question
- Example:
“If this hypothesis were wrong, where would it break down?” “Please evaluate it from the perspective of the irreversibility of decision-making.”
- Managing Dialogue Branches
- 1 thread = 1 topic. If the discussion branches off, add a heading and save it.
- Small Experiments
- 15–30-minute small tests. Determine the metrics to measure in advance.
- Recording and Reuse
- Turn successful “questions” into templates. Use them as a starting point for the next round.
Practical Use Cases (All Bulleted for “Immediate Implementation”)
1. Planning (Blogs / Videos / Products)
- Organize in the following order: Purpose → Target Audience → Benefits → Differentiation → Validation Plan
- Prompt Example
“Identify three types of target audiences and list the ‘solutions they’ve already tried but remain dissatisfied with’ for each type. Work backward from there to formulate a differentiation hypothesis.”
2. Learning (Indexing New Fields)
- Table of Contents → Terminology Grouping → Minimal Theory → Typical Counterarguments → Representative Implementation
- Prompt Example
“List five ‘points prone to misunderstanding’ regarding this topic in bullet form. Include a short review question for each point.”
3. Writing (Outline → Paragraphs → Revision)
- Outline → Claim → Evidence → Anticipating Counterarguments → CTA
- Prompt Example
“Rearrange the text into the sequence ‘claim / evidence / example / counterargument and reaffirmation,’ and cut out redundant phrasing.”
4. Decision-Making (Buy / Skip / Wait)
- Conditions for Success / Critical Risks / Exit Strategy / Reevaluation Date
- Prompt Example
“First, list three ‘patterns that lead to buyer’s remorse,’ then identify the warning signs and preemptive measures for each.”
5. Reflection (Weekly Review)
- This Week’s Decisions / Predictions vs. Results / Reasons for Discrepancies / Next Hypothesis
- Prompt Example
“Create five questions to distinguish between ‘just luck’ and ‘actual skill,’ and classify this week’s results accordingly.”
Failure Patterns and Countermeasures
- Seeking the “right answer” immediately → First, articulate the assumptions.
- Topics get mixed up → Split the thread and manage it with headings.
- Only using convenient information → Include one round of generating counterarguments → restating your position.
- Delegating everything → Make requests by clearly stating evaluation criteria and constraints.
- Leaving things unfinished → Implement a set process of “documentation → creating templates → speeding up the next round.”
AI as an “Extended Mind” (Philosophical Basics)
- Autonomy vs. Dependence: People make the decisions; tools support their thinking.
- Accountability: Transparency in the process (logs of assumptions and judgment criteria) is key.
- Originality: AI excels at “rearranging the known.” It is up to you to imbue it with individuality through constraints and experience.
- Mental Hygiene: Be aware of noise (emotions and biases), visualize it through dialogue, and address it.
15-Minute Mini-Experiment: Create a Single “Thinking Template”
- Theme: Choose one important decision from this week
- Procedure
- Assumptions / Evaluation Criteria / Conditions for Success / Critical Issues to Avoid
- 3 Alternatives → Brief commentary on trade-offs
- Implementation Steps → Who, When, What → Conditions for Withdrawal
- Final Step: Abstract into a set of questions you can use next time

Summary: When Tools Change, So Does Your Way of Thinking
From “quickly finding the right answer” to “making choices you’re satisfied with.”
ChatGPT is a thinking tool designed for this purpose. Let’s start by changing the way we approach even today’s small decisions.
