Statement–Conclusion

Core Rules

  • Only use information given in the statement — don't bring outside knowledge or real-world assumptions
  • "Follows" = must be logically true from the statement alone, no extra inference allowed
  • A conclusion that sounds true or reasonable in real life but isn't actually stated does NOT follow
  • Watch for absolute words ("all", "only", "never") in the conclusion that go beyond what the statement supports

Common Traps

  • Overgeneralization: statement talks about a specific case, conclusion generalizes to everyone
  • Reversed causation: statement says A causes B, conclusion assumes B causes A
  • Assumed intent: statement reports an action, conclusion assumes a motive not stated
  • Real-world plausibility bias: the conclusion "feels" true from general knowledge, but the statement itself never said it

Worked Examples

  1. Statement: "The company reduced prices by 20% last month." Conclusion: "The company's profits fell." → Does not follow (price cuts don't necessarily mean lower profit — volume could've risen)
  2. Statement: "All employees who arrived late were marked absent." Conclusion: "Some employees arrived late." → Does not follow (the statement is conditional — it doesn't confirm anyone was actually late)
  3. Statement: "Only members are allowed inside the hall." Conclusion: "All members are allowed inside the hall." → Does not follow ("only members" restricts non-members, it doesn't guarantee all members get in — e.g. there could be a capacity limit)
  4. Statement: "Since the new policy was introduced, complaints have decreased." Conclusion: "The new policy caused the decrease in complaints." → Does not follow (correlation isn't stated as causation)

Drill

  1. Statement: "Most students who studied daily passed the exam." Conclusion: "All students who passed studied daily." — Does not follow
  2. Statement: "The bridge was closed for repairs for three days." Conclusion: "Traffic was affected during those three days." — Does not follow (plausible, but not stated)
  3. Statement: "Every applicant who scored above 90% received a scholarship." Conclusion: "Someone scored above 90%." — Does not follow unless scholarships were actually given (conditional, not confirmed)
  4. Statement: "The factory increased output after switching suppliers." Conclusion: "The new supplier caused the increase." — Does not follow
