Unverified Content Outline - Intellectual Reasoning Foundations
What this section covers
No official content outline was supplied for this exam, so the safest preparation is to build transferable intellectual skills that most reasoning batteries test: argument analysis, deductive validity, conditional logic, quantitative literacy, and careful reading. Treat the list below as a framework to verify against official materials, not as a disclosed syllabus.
Core concepts
- Conclusion vs. evidence: identify the claim being supported before judging the support.
- Validity vs. truth: a valid argument can have false premises; true premises do not guarantee validity.
- Necessary vs. sufficient conditions: “only if” introduces a necessary condition; “if” introduces a sufficient one.
- Quantifiers: “all,” “some,” and “none” have precise logical meanings; “some” means at least one, not most.
- Correlation and causation: a statistical association alone does not establish a causal claim.
- Base rates: ignore them and probability judgments go wrong.
Common traps
Questions often swap necessary and sufficient conditions, shift scope from “some” to “all,” use extreme wording, or present a plausible but irrelevant statistic. In reading items, watch for answer choices that are true but do not answer the question.
Worked example
Premises: All analysts are careful. Some careful people are impatient. Question: Must some analysts be impatient? No. The “some careful” group may contain no analysts. Test by constructing a counterexample: analysts are careful and patient; impatient careful people exist outside the analyst group. Both premises hold, yet the conclusion fails.
Rule of thumb: when a conclusion seems tempting, try to draw a counterexample diagram; if one exists, the inference is invalid.
