A practical reading method
Track a Thought Experiment Without Treating It as Evidence
Mark the page and state the proposition the scenario is designed to test. List the assumptions the author holds constant and any realistic factors removed. Write the inference supported by the case and the empirical question that still needs evidence.
Use this in philosophy, economics, science, or ethics writing that relies on hypothetical scenarios. A vivid hypothetical can feel like empirical proof. Separating purpose, assumptions, and limit keeps the reasoning honest.

Method
Build the note
1. Mark the page and state the proposition the scenario is designed to test.
2. List the assumptions the author holds constant and any realistic factors removed.
3. Write the inference supported by the case and the empirical question that still needs evidence.
Example
See the boundary in practice
The island scenario tests a consistency claim under perfect information; it does not show how people behave with uncertainty.
Quality check
Before you trust the note
The note should identify the logical job of the scenario and one claim it cannot prove.
