Effect–Cause Reversal

Introduction

In many reasoning questions, the given statements are written in reverse order - the effect appears first, and the cause comes later. Understanding this reversal helps you avoid confusion and identify the true reason behind an event. This pattern is especially important in competitive exams where cause-effect logic is tested through indirect sequencing.

Pattern: Effect–Cause Reversal

Pattern

The key concept is: when the effect is mentioned before the cause, you must mentally reorder the events to identify the true cause-effect direction.

Step-by-Step Example

Question

1️⃣ The schools declared a holiday.
2️⃣ A massive storm hit the coastal area.

Which of the following correctly represents the cause-effect relationship?
(A) 1 → Cause; 2 → Effect
(B) 2 → Cause; 1 → Effect
(C) Both are effects of a common cause
(D) Both are independent

Solution

  1. Step 1: Identify which event happened first

    The storm occurred before the schools declared a holiday.

  2. Step 2: Determine logical dependency

    The schools closed because of the storm - so the storm is the cause.

  3. Step 3: Reverse the apparent order

    Although the effect (holiday) is stated first, the true order is: storm → holiday.

  4. Final Answer:

    2 → Cause; 1 → Effect → Option B

  5. Quick Check:

    If no storm had occurred, would schools still close? No - storm is the cause ✅

Quick Variations

1. Sometimes both statements are reversed intentionally to test time-order reasoning.

2. The effect might appear more prominent, but the underlying cause is hidden later.

3. Used often in current affairs or situational reasoning questions.

Trick to Always Use

  • Ask: “Which event naturally happens first?” - that’s the cause.
  • Mentally reorder the statements before deciding the relationship.
  • Remember: effects never happen before their causes.

Summary

Summary

  • When effect appears before cause, reorder mentally to find the logical sequence.
  • Cause always happens earlier; effect follows as a result.
  • Used frequently in exams to test attention to sequence and logic.
  • Always check if the earlier event explains why the later one occurred.

Example to remember:
“Holiday declared → Storm occurred earlier” → The storm is the cause, not the holiday.

Practice

(1/5)
1. 1️⃣ The hospital staff worked overtime. 2️⃣ There was a sudden rise in dengue cases. Identify the correct cause-effect direction.
easy
A. 1 → Cause; 2 → Effect
B. 2 → Cause; 1 → Effect
C. Both are independent
D. Both are effects of a common cause

Solution

  1. Step 1: Observe sequence

    The hospital staff worked overtime because dengue cases increased suddenly.

  2. Step 2: Identify true order

    The rise in dengue cases came first; extra work was the result.

  3. Final Answer:

    2 → Cause; 1 → Effect → Option B

  4. Quick Check:

    No dengue rise → no overtime → correct cause-effect ✅
Hint: When workload increases due to an event, the event is the cause.
Common Mistakes: Assuming staff overtime caused more patients.
2. 1️⃣ The match was postponed. 2️⃣ Heavy rain started in the city. Choose the correct cause-effect relationship.
easy
A. 1 → Cause; 2 → Effect
B. 2 → Cause; 1 → Effect
C. Both are independent
D. Both are effects of a common cause

Solution

  1. Step 1: Analyze timing

    The rain occurred before the match was postponed.

  2. Step 2: Logical connection

    Match was cancelled because of rain → effect-cause reversal.

  3. Final Answer:

    2 → Cause; 1 → Effect → Option B

  4. Quick Check:

    If no rain, match continues → rain is the cause ✅
Hint: Weather events often cause scheduling changes.
Common Mistakes: Thinking postponement caused rain.
3. 1️⃣ Many people started working from home. 2️⃣ The government imposed a city-wide lockdown. Choose the correct cause-effect pair.
easy
A. 1 → Cause; 2 → Effect
B. Both are independent
C. 2 → Cause; 1 → Effect
D. Both are effects of a common cause

Solution

  1. Step 1: Observe order

    Lockdown happened first; people shifted to remote work after.

  2. Step 2: Logical link

    Lockdown (cause) led to work-from-home (effect).

  3. Final Answer:

    2 → Cause; 1 → Effect → Option C

  4. Quick Check:

    No lockdown → offices open → effect disappears ✅
Hint: When restriction comes before reaction, the restriction is the cause.
Common Mistakes: Assuming people working from home caused lockdown.
4. 1️⃣ The share prices of several companies fell sharply. 2️⃣ The government announced new tax regulations. Identify the correct relationship.
medium
A. 1 → Cause; 2 → Effect
B. 2 → Cause; 1 → Effect
C. Both are independent
D. Both are effects of a common cause

Solution

  1. Step 1: Determine time order

    Tax policy was introduced first; market reacted later.

  2. Step 2: Establish dependency

    Policy change caused market fall.

  3. Final Answer:

    2 → Cause; 1 → Effect → Option B

  4. Quick Check:

    No new regulation → prices stable → valid reversal ✅
Hint: Government or economic actions usually come before market reactions.
Common Mistakes: Assuming stock fall led to tax changes.
5. 1️⃣ The streets were waterlogged. 2️⃣ The municipal drainage system failed. Determine the correct cause-effect order.
medium
A. 1 → Cause; 2 → Effect
B. Both are independent
C. 2 → Cause; 1 → Effect
D. Both are effects of a common cause

Solution

  1. Step 1: Identify dependency

    Drainage system failure happened first, which led to waterlogging.

  2. Step 2: Reverse order

    Though streets waterlogged (effect) is stated first, actual cause is drainage failure.

  3. Final Answer:

    2 → Cause; 1 → Effect → Option C

  4. Quick Check:

    Proper drainage → no waterlogging → cause confirmed ✅
Hint: When a system fails before visible outcome, the failure is the cause.
Common Mistakes: Treating waterlogging as the cause of system failure.
