Huasheng Shisan Logical Reasoning Method

Problem It Addresses

In logical-inference questions, the hard part is often not reading the stem but quickly identifying the question type, comparing the strength of strengthening or weakening options, and avoiding high-frequency attribution traps. This skill turns that process into an executable method: identify the question type, enter the corresponding reasoning path, then use strength ranking and a trap checklist to reduce option misjudgment.

How It Works

The skill is organized around the Huasheng Shisan method described in the SKILL.md content. It includes:
- Question-type decision tree: identify the logical-reasoning category first, then follow the matching solution path.
- Strength quick reference: for strengthening options, bridge > premise > exclude alternative cause > supplement evidence > strengthen sample > reverse strengthening; for weakening options, break bridge > negate premise > reverse causation > alternative cause > reverse weakening > counterexample > weaken sample.
- Special cases: for support items with a conclusion but no premise, check whether the option can explain or concretize the abstract conclusion.
- General strength comparison: compare options by questioning mode, argumentation mode, option scope, degree wording, and topic relevance.
- Trap checklist: covers grouping errors, pseudo alternative causes, affirmation-of-cause fallacies, composition fallacies, non-cause options, analogical weakening or support, static descriptions, and hasty generalizations.

Scope and Notes

This resource is useful for structuring logic-judgment problems, comparing option strength, and reviewing traps. It relies on a workflow of type identification, strength ranking, and trap checking. For special question types not covered by the material, or items requiring external factual background, judgments should still be grounded in the stem, subject knowledge, and specific exam rules.
