Each of the following arguments contains a serious logical vulnerability. Match each flawed argument with the abstract description that most accurately identifies its primary reasoning flaw.
- Archaeologist: Every individual obsidian blade recovered from the highland excavation site was fashioned using rudimentary direct percussion techniques. Therefore, the architectural stone masonry across the settlement as a whole must have been built using primitive construction methods.Illicitly infers that an entire structure possesses a characteristic solely because each of its constituent components possesses that characteristic.
- Bioethicist: Independent institutional oversight is an indispensable prerequisite for ensuring that a clinical drug trial maintains ethical integrity. Hence, any pharmaceutical trial that successfully secures such institutional oversight is thereby guaranteed to maintain impeccable ethical standards.Treats a factor that is necessary for achieving a certain condition as though it were sufficient to guarantee that condition.
- Economist: Financial decisions are defined as economically rational only if they maximize anticipated monetary returns. Because the venture founder chose to distribute surplus company equity among entry-level staff rather than reinvesting for maximum monetary yield, the founder's cognitive faculties must be fundamentally irrational.Equivocates between a technical, domain-specific definition of a key term and a broader, psychological sense of that term.
- Forensic Analyst: The audit proved conclusively that the suspect did not hold the master encryption credentials necessary to bypass the corporate database directly. It follows that the unauthorized exfiltration of proprietary records could only have been executed by an external network intruder.Presumes without justification that only two alternative explanations exist, ignoring other viable possibilities.
Cevap
Match the archaeologist's argument with the description of the part-to-whole composition flaw; match the bioethicist's argument with the description of confusing a necessary condition for a sufficient one; match the economist's argument with the description of equivocation between technical and general senses of a term; match the forensic analyst's argument with the description of assuming only two alternatives exist.
Each argument corresponds precisely to an established logical fallacy archetype: the archaeologist infers a property of a whole from properties of its parts; the bioethicist mistakes a necessary condition for a sufficient one; the economist trades on two distinct meanings of rationality; and the forensic analyst relies on a false dichotomy by failing to exhaust all alternative explanations.
