Introduction to Basic Assumption Identification

Basic Assumption Identification problems present a statement or argument, and you must identify the underlying assumption(s) that the speaker takes for granted. Assumptions are unstated premises that must be true for the argument to hold logically.

Prerequisites

Understanding of logical arguments Ability to distinguish stated vs unstated information Critical thinking basics Knowledge of premise-conclusion relationships
Why This Matters: Basic Assumption Identification forms the foundation of critical reasoning. You can expect 2-3 questions in SSC CGL, 2-3 in Banking PO, and 2-3 in Railways RRB exams.

How to Solve Basic Assumption Identification Problems

1

Step 1: Read the statement carefully and identify the main conclusion being drawn

2

Step 2: Identify any evidence or reasons given to support the conclusion

3

Step 3: Ask yourself: What must be true for this conclusion to follow from the evidence?

4

Step 4: Look for gaps between the evidence and the conclusion

5

Step 5: The assumption fills these gaps - it connects the evidence to the conclusion

6

Step 6: Check if the assumption is unstated (not explicitly mentioned in the statement)

7

Step 7: Verify that the assumption is necessary for the argument (without it, the argument falls apart)

8

Step 8: Select the assumption that best supports the logical connection

Pro Strategy: Always identify the conclusion first. Then find the logical gap between the evidence and conclusion. The assumption is the missing link that connects them.

Example Problem

Example: Statement: 'The government should increase minimum wage to help reduce poverty.' What is the assumption? Solution: Step 1: Conclusion: Government should increase minimum wage Step 2: Evidence: It will help reduce poverty Step 3: Gap: Does increasing minimum wage actually reduce poverty? Step 4: Assumption: Higher wages reduce poverty Step 5: This is unstated but necessary for the argument Answer: Higher wages reduce poverty

Pro Tips & Tricks

  • Assumptions are NEVER stated explicitly in the argument
  • Look for the logical leap - what must be true for the argument to make sense?
  • Use the negation test: If negating a statement makes the argument invalid, that statement is an assumption
  • Assumptions often involve cause-effect relationships
  • Don't confuse assumptions with conclusions - conclusions are stated, assumptions are not
  • Assumptions are typically general principles or beliefs, not specific facts

Shortcut Methods to Solve Faster

Negation Test: Assume the opposite of candidate assumption → if argument collapses → it's an assumption
Bridge Assumption: Connects evidence to conclusion directly
Assumptions often begin with 'that' or are implied by conditional statements
Watch for words like 'since', 'because', 'therefore' - they signal argument structure

Common Mistakes to Avoid

Identifying a stated fact as an assumption
Confusing assumptions with conclusions
Selecting an assumption that is too specific or too broad
Not using the negation test to verify
Overlooking multiple assumptions in complex arguments
