Common Cause Medium
Common Cause problems present two statements that are both effects of some unstated common cause. Neither statement causes the other; instead, they are parallel outcomes of a shared underlying event or condition. These problems test your ability to recognize when events are correlated through a common origin rather than directly causing each other.

Introduction to Common Cause Medium
Common Cause problems present two statements that are both effects of some unstated common cause. Neither statement causes the other; instead, they are parallel outcomes of a shared underlying event or condition. These problems test your ability to recognize when events are correlated through a common origin rather than directly causing each other.
Prerequisites
How to Solve Common Cause Medium Problems
Step 1: Read both statements carefully
Step 2: Check if Statement I could cause Statement II
Step 3: Check if Statement II could cause Statement I
Step 4: If neither directly causes the other, consider a common cause
Step 5: Identify a plausible event that could lead to both statements
Step 6: Verify that the common cause logically explains both outcomes
Step 7: Conclude that both statements are effects of a common cause
Example Problem
Example: Statement I: Unemployment rate increased significantly. Statement II: Consumer spending dropped sharply. Solution: Step 1: Read both statements Step 2: Can unemployment cause reduced spending? Yes, but is that the only explanation? Step 3: Can reduced spending cause unemployment? Possibly, through reduced production Step 4: Both could be true, but they might share a common cause Step 5: Economic recession could cause both high unemployment AND low consumer spending Step 6: A common cause (recession) explains both outcomes Step 7: Therefore, both are effects of a common cause Answer: Both statements are effects of some common cause
Pro Tips & Tricks
- Look for events that naturally occur together without direct causation
- Economic downturns cause multiple negative outcomes (unemployment, reduced spending, business failures)
- Natural disasters cause multiple effects (property damage, displacement, economic loss)
- Government policies cause multiple societal changes
- Technological advances cause multiple industry shifts
- If A and B are correlated but neither logically causes the other, suspect a common cause
