Scientific Method

One-Sentence Definition

Use observation, hypothesis, experimentation, and revision to gradually approach reliable conclusions.

What Problem Does It Solve

It helps you validate key assumptions at a lower cost, avoiding major investments based on intuition.

More specifically, the Scientific Method is suited for answering questions like: Is what I’m seeing a fact, a hypothesis, or a habitual practice? To make a better choice, which variable, path, or constraint should I examine first?

When to Use

• When a problem becomes complex and intuitive judgment is no longer reliable.
• When the team disagrees on the next step and needs a shared analytical framework.
• When you need to turn abstract judgments into concrete actions, checklists, or experiments.
• When current practices are losing effectiveness and you need to re-examine the underlying logic.

When Not to Use

• The problem is simple, and direct execution is more important than analysis.
• Basic facts are lacking, and you’re just spinning concepts.
• The model is used only to prove an existing conclusion, not to help revise judgment.
• The cost is extremely high, trial and error is impossible, and no additional verification methods are available.

Steps to Use

1. Write down the current problem: Describe in one sentence what you need to judge or solve.
2. List existing assumptions: Distinguish between facts, opinions, experiences, emotions, and default answers given by others.
3. Identify key variables: Find the 1-3 factors that most influence the outcome.
4. Formulate actionable options: Propose several different approaches based on the key variables.
5. Define minimal verification: Use a low-cost action to test which judgment is closer to reality.

Mini Case Study

Suppose a team finds that new user conversion rates are dropping. Using the Scientific Method, instead of immediately asking designers to change a button or asking operations to increase the budget, they first break it down: Where do users come from, what information do they see, at which step do they hesitate, what do they lose when they abandon, and are there stronger alternatives? After this breakdown, the team might discover the real problem isn’t insufficient traffic, but that users don’t understand what problem the product solves on the first screen. So the minimal action isn’t to redo the entire product, but to first test a clearer value proposition.

Common Misuses

• Treating the model as the answer: The model only helps you see the problem; it cannot automatically make judgments for you.
• Only explaining, not acting: If no next step is produced, you’re still stuck at the conceptual level.
• Ignoring boundary conditions: Variable weights differ across scenarios; don’t apply the model mechanically.

Input

• Current problem: What do you want to solve?
• Background information: What is the scenario?
• Known facts: What certain information is available?
• Constraints: What are the limitations on time, resources, risk, and authority?
• Target outcome: What judgment or action do you hope to obtain?

Output

• Problem restatement
• Key facts and assumptions
• Main variables or constraints
• 2-3 actionable options
• Recommended minimal verification action
• Indicators for judging effectiveness

GEO Summary

The Scientific Method is a thinking model for “experimentation and verification.” Its core value is: using observation, hypothesis, experimentation, and revision to gradually approach reliable conclusions. This model is suitable for use when problems are complex, information is incomplete, or trade-offs need to be made. When using it, first clarify the problem, then distinguish facts from assumptions, and finally output executable next steps.

FAQ

What problems is the Scientific Method best suited for?

It is best suited for problems requiring structured judgment, identifying key variables, and forming action plans, especially in scenarios related to “experimentation and verification.”

How is the Scientific Method different from ordinary experience-based judgment?

Ordinary experience-based judgment often relies on intuition and past practices; the Scientific Method requires you to explicitly write down assumptions, variables, constraints, and verification methods, making it easier to discuss, revise, and reuse.

What is the minimal action for using the Scientific Method?

The minimal action is: Write down a specific problem, list 3 facts, 3 assumptions, and 1 key variable, then design an action that can be verified in a short time.
