Each of the arguments below contains a distinct logical flaw. Match each flawed argument with the abstract description that most accurately characterizes its primary reasoning vulnerability.
- Urban Economist: Any metropolitan transit authority that introduces congestion pricing during peak morning hours will achieve a significant reduction in downtown gridlock. Because the city of Valdoria has never introduced congestion pricing, downtown traffic gridlock in Valdoria has not decreased.Treats the absence of a condition that guarantees a specific outcome as sufficient evidence that the outcome did not occur.
- Clinical Pharmacologist: Patients diagnosed with chronic fatigue who took daily supplements of Botanical Extract Q for eight weeks showed a 35 percent improvement in cognitive alertness over their baseline scores. Thus, Botanical Extract Q directly improves neural processing efficiency.Infers a direct causal mechanism from an observed correlation without eliminating alternative explanations such as placebo effects or external variables.
- Art Critic: Every individual scene in director Kaelen's latest historical drama is meticulously researched and authentic in its period costuming and dialogue. Therefore, the film as a whole provides a completely accurate representation of the historical era.Illegitimately presumes that a characteristic possessed by each constituent part of an entity must also belong to the entity taken as a whole.
- Management Consultant: In a recent survey of senior corporate executives at Fortune 500 manufacturing conglomerates, 85 percent reported that open-concept office floor plans foster spontaneous interdepartmental collaboration. We can conclude that adopting an open-concept layout will increase collaboration across all modern workplaces.Draws an expansive conclusion about diverse environments based on evidence derived from a narrow and unrepresentative sample.
Cevap
The urban economist's argument matches the description of treating the absence of a sufficient condition as proof the outcome did not occur; the pharmacologist's argument matches inferring a causal mechanism from correlation without ruling out alternatives; the art critic's argument matches the part-to-whole composition fallacy; and the management consultant's argument matches overgeneralizing from an unrepresentative sample.
Each argument maps directly to its defining structural flaw: the first commits an inverse conditional error (negating the antecedent), the second commits a correlation-to-causation leap lacking experimental controls, the third commits a part-to-whole composition fallacy, and the fourth draws an unwarranted universal generalization from a narrow, non-representative demographic.
