Theory to Toy Cases
Make the idea concrete before scaling it up.
Workflow
- Restate the abstract claim in the smallest possible setting.
- Build 2-5 minimal cases:
- a friendly case where the idea should work
- a boundary case
- a failure case
- a misleading case that appears to work for the wrong reason
- If useful, write a tiny simulation or symbolic example.
- Compare predicted behavior vs actual behavior.
- Extract what the toy case teaches about the full problem.
Good toy cases
Prefer cases that are:
- low-dimensional
- analytically tractable
- numerically checkable
- likely to expose hidden assumptions
Rules
- Do not use toy cases as proof.
- Say what scales and what does not.
- If a toy case fails, treat that as signal, not annoyance.
Output shape
Return:
- Abstract idea
- Minimal setup
- Cases
- What each case shows
- Implication for the full research question
- What the toy cases cannot establish
