LessonsAnalogy: Original and New Cases, Common Cause, Co-variation and EliminationQuiz

Use these questions when evaluating an analogy:
1. What is the original case and its known judgment?
2. What new case is being considered and what is to be proved?
3. Which feature is shared?
4. Is it causally relevant or an accidental resemblance?
5. Is its relevance supported by co-variation, elimination, or other evidence?
6. Are there counterexamples or disanalogies that defeat the transfer?

Answering these questions separates the structure of the analogy from the strength of its supporting argument.
