The following arguments each demonstrate a common logical vulnerability. Which abstract description best identifies the flawed pattern of reasoning used in each argument?
- A thriving marine ecosystem invariably features a diverse population of apex predators, as these predators regulate the populations of smaller marine life. Survey data from the Emerald Reef indicates a highly diverse population of apex predators currently inhabits the area. Therefore, the Emerald Reef must be a thriving marine ecosystem.Treats a characteristic that is known to be true of every member of a certain category as if it were sufficient to guarantee membership in that category.
- To stabilize the endangered wolf population, wildlife officials must introduce captive-bred wolves into the wild. After all, the only other suggestion—restricting human development in the wolves' natural habitat—has been repeatedly rejected by the regional legislature. Thus, introducing captive-bred wolves is the only path forward.Bases its conclusion on the unstated assumption that there are no other viable alternatives beyond the two explicitly considered.
- The globally renowned Horizon Tech Corporation has consistently been recognized as the most innovative tech company of the decade, pioneering breakthroughs in quantum computing and artificial intelligence. Consequently, Elias Vance, who works as a junior accountant at Horizon Tech, must be an exceptionally innovative employee.Presumes, without providing justification, that an attribute of a collective entity is also an attribute of each of its constituent parts.
- A comprehensive dietary study found that individuals who consume high amounts of artificially sweetened beverages suffer from chronic fatigue syndrome at triple the rate of those who do not. This demonstrates that consuming artificially sweetened beverages directly contributes to the onset of chronic fatigue syndrome.Takes a mere statistical correlation as definitive proof of a causal relationship without ruling out alternative explanations.
Answer
The arguments logically pair as follows: The marine ecosystem argument matches the description of confusing a necessary condition with a sufficient one. The wolf population argument matches the description of a false dilemma. The tech company argument matches the description of a part-to-whole (division) error. The dietary study argument matches the description of confusing correlation with causation.
Each argument contains exactly one distinct logical error that perfectly mirrors the corresponding abstract description. The marine ecosystem argument demonstrates an illegal reversal (necessary vs. sufficient). The wolf argument demonstrates a false dichotomy. The tech company argument demonstrates a flaw of division. The dietary argument demonstrates a correlation-causation fallacy.
