Introduction to Contradictory Statement Analysis
Contradictory Statement Analysis problems present statements that conflict with each other. You must identify the logical inconsistency and determine what can be concluded about the contradictory information.
Prerequisites
How to Solve Contradictory Statement Analysis Problems
Step 1: Read all given statements carefully
Step 2: Identify statements that make opposing claims about the same subject
Step 3: Check for direct contradictions (e.g., 'All A are B' vs 'Some A are not B')
Step 4: Check for indirect contradictions through logical chaining
Step 5: If two statements cannot both be true, they are contradictory
Step 6: Determine what can be concluded from the contradiction (e.g., at least one statement is false)
Step 7: Select the conclusion that correctly identifies the inconsistency
Example Problem
Example: Statements: 'All employees must work from office.' 'The company policy allows flexible remote work.' 'John works entirely from home and follows company policy.' What can be concluded? Options: A) There's a contradiction in the policies B) John is violating company rules C) Remote work is not really allowed D) All employees work from home Solution: Step 1: First statement says all employees must work from office (no remote work) Step 2: Second statement says policy allows flexible remote work Step 3: These two statements directly contradict each other Step 4: Third statement says John works from home and follows policy Step 5: Since the policies contradict, any conclusion about compliance is ambiguous Step 6: The only valid conclusion is that the policies are contradictory Answer: There's a contradiction in the policies
Pro Tips & Tricks
- P and not-P cannot both be true
- 'All A are B' contradicts 'Some A are not B'
- 'No A are B' contradicts 'Some A are B'
- If statements lead to a logical paradox, the information is inconsistent
- Contradiction does not tell you which statement is false, only that not all can be true
- Sometimes the contradiction is between a statement and an implied necessary condition
