Introduction to Argument Strengthen/Weaken

Argument Strengthen/Weaken problems present an argument and several pieces of additional evidence. You must identify which evidence most strengthens (supports) or weakens (undermines) the argument. These problems test your ability to evaluate how new information affects existing arguments.

Prerequisites

Argument structure analysis Evidence evaluation Causal reasoning Logical relationships
Why This Matters: Argument Strengthen/Weaken problems appear in 2-3 questions in Banking PO and CAT exams. They test advanced critical reasoning.

How to Solve Argument Strengthen/Weaken Problems

1

Step 1: Read the argument and identify its main conclusion

2

Step 2: Identify the evidence or reasoning used to support the conclusion

3

Step 3: For strengthen questions: Look for evidence that confirms the relationship

4

Step 4: For weaken questions: Look for evidence that contradicts or offers alternatives

5

Step 5: Check if the evidence directly addresses the causal claim

6

Step 6: Consider if the evidence provides a counterexample or alternative explanation

7

Step 7: Select the evidence that has the strongest impact on the argument

8

Step 8: Justify your selection

Pro Strategy: The best strengthening evidence directly confirms the relationship claimed in the argument. The best weakening evidence directly contradicts it or provides a compelling alternative explanation. Avoid evidence that is true but irrelevant to the core claim.

Example Problem

Example: Argument: 'Working from home increases productivity because employees have fewer distractions.' Which evidence most STRENGTHENS this argument? A) Some employees prefer working from home B) Companies that switched to remote work saw 25% productivity gains C) Offices can be noisy environments D) Working from home saves commuting time Solution: Step 1: Conclusion: Working from home increases productivity Step 2: Reasoning: Employees have fewer distractions Step 3: Option A discusses preference, not productivity → weak Step 4: Option C is true but doesn't directly support the claim Step 5: Option D addresses commuting, not distractions/productivity Step 6: Option B provides direct evidence of productivity gains → STRONGEST Answer: B

Pro Tips & Tricks

  • Strengthen: Look for evidence that confirms the cause-effect relationship
  • Strengthen: Look for evidence that eliminates alternative explanations
  • Strengthen: Look for evidence that shows the relationship in different contexts
  • Weaken: Look for evidence that contradicts the claimed relationship
  • Weaken: Look for evidence that provides alternative causes
  • Weaken: Look for counterexamples where the claimed relationship fails

Shortcut Methods to Solve Faster

If argument claims X causes Y, strengthener shows X→Y occurs, weakener shows X→Y doesn't occur
Look for the option that most directly addresses the core causal link
Eliminate options that are true but irrelevant to the conclusion
Avoid options that only restate the premise

Common Mistakes to Avoid

Choosing evidence that is true but doesn't affect the argument
Confusing correlation with causation when evaluating evidence
Selecting weakening evidence that actually strengthens (or vice versa)
Overlooking the most direct evidence in favor of more dramatic but less relevant options
