Critical reasoning — identify implicit assumptions Statement: “The successful man has the ability to judge himself correctly.” Assumptions to evaluate: I. Inability to judge oneself correctly causes failure. II. Judging others is of no use to a successful person. III. A successful person cannot make a wrong judgement.
Correct Answer: None is implicit
Introduction / Context:The statement attributes one ability to successful people: accurate self-judgement. Our task is to see whether broader claims about failure, judging others, or infallibility are necessary assumptions, or merely tempting extrapolations.
Given Data / Assumptions:
- Claim: Successful people can judge themselves correctly.
- I: Failure results from inability to judge oneself.
- II: Judging others is useless for success.
- III: Successful people never make wrong judgements.
Concept / Approach:From “X has ability A,” do not infer negations or universals about other abilities or absolute error-free performance. The scope is descriptive, not exhaustive or exclusive.
Step-by-Step Solution:
I is not required: many factors cause failure; the statement neither asserts nor needs a sole cause.II is not required: the statement is silent about judging others; usefulness of other abilities is not addressed.III is not required: having the ability to judge oneself correctly does not mean one never errs; it could be a tendency, not perfection.Verification / Alternative check:Rephrase: “One trait of many successful people is sound self-assessment.” This stands without I–III.
Why Other Options Are Wrong:
- Any combination or “All” imports claims the original statement never needed to make.
Common Pitfalls:Equating a cited trait with an exhaustive definition of success; turning a capacity into a claim of infallibility.
Final Answer:None is implicit
