Analyze the reasoning in each of the following short arguments. Pair each argument with the abstract description that most accurately identifies its primary logical vulnerability.
- If a municipality enacts restrictive zoning ordinances, local property values will invariably rise. Over the past decade, property values in the township of Oakhaven have risen dramatically. Thus, Oakhaven must have enacted restrictive zoning ordinances.It mistakenly treats a condition that is sufficient to guarantee a particular outcome as though it were a necessary requirement for that outcome.
- Every individual member of the Metropolitan String Quartet is an internationally renowned virtuoso. It logically follows that the Metropolitan String Quartet itself is an internationally renowned ensemble.It presumes, without providing adequate justification, that a characteristic of individual components is inherently a characteristic of the entity they comprise.
- Recent sociological data reveals that regions with higher rates of daily internet consumption also report higher incidences of generalized anxiety. Therefore, it is evident that excessive internet consumption induces anxiety.It concludes that one phenomenon causes another based entirely on the observation that the two phenomena occur concurrently.
- The two independent art critics we surveyed found the new abstract installation completely devoid of meaning. This definitively proves that no patron visiting the gallery will be able to derive meaning from the installation.It draws an absolute, sweeping conclusion about an entire population based on a sample that is far too small to be demonstrably representative.
Answer
The correct pairings match each specific flawed argument to its corresponding logical fallacy: the zoning argument contains an illegal reversal (sufficient/necessary flaw), the quartet argument commits a composition fallacy (part-to-whole), the internet argument confuses correlation with causation, and the art exhibit argument relies on an unrepresentative sample.
Each pairing accurately maps the specific logical vulnerability of the argument to its formal definition. The zoning argument confuses necessary and sufficient conditions. The quartet argument falsely equates the properties of individual parts to the whole. The internet argument jumps from correlation to causation. The art exhibit argument overgeneralizes from an exceptionally small sample.
