Analyze the logical vulnerabilities present in the four domain-specific arguments below. Map the text of each argument to the precise structural characterization of its reasoning error.
- Economics: Financial analysts note that every individual algorithmic trading model deployed by the banking consortium is rigorously programmed to suppress price volatility during sudden market shocks. Consequently, if all of these proprietary models are deployed simultaneously during a severe economic shock, the overall market volatility will undoubtedly be suppressed.Draws a conclusion about the properties of an entire system based solely on the premise that each of the system's independent components possesses those properties.
- Linguistics: For linguists to conclusively demonstrate that two seemingly disparate regional dialects share a common ancestral proto-language, they must establish a comprehensive pattern of systematic phonetic correspondences. The recent phonological analysis of the highland and coastal dialects has revealed precisely such a pattern. Thus, this analysis definitively establishes that the dialects share a common ancestor.Treats a condition without which a particular claim cannot be firmly established as a condition that, if met, guarantees the truth of that claim.
- Policy: Councilman Torres argues that municipal zoning laws should be overhauled to allow for mixed-use residential development in the industrial sector. However, we should reject this proposal out of hand. Torres is a silent partner in a real estate firm that recently purchased large tracts of land in that exact sector, meaning he stands to profit immensely from the rezoning.Dismisses a proposal's conclusion not by addressing its substantive merits, but rather by pointing out a vested interest held by the person making the proposal.
- Geophysics: According to geophysical theories, the presence of a massive subterranean iron deposit or a recent, localized meteorite impact will each independently generate a significant magnetic anomaly. Our survey of the Tularosa Basin detected such an anomaly, yet extensive excavations have definitively ruled out a meteorite impact. Therefore, there must be a massive subterranean iron deposit beneath the basin.Takes for granted that because certain specific conditions are independently sufficient to produce a given phenomenon, one of those conditions must be the cause of the phenomenon.
Answer
Economics maps to the system/components flaw (Composition). Linguistics maps to the necessary/sufficient confusion. Policy maps to the vested interest attack (Source Motive). Geophysics maps to assuming sufficient conditions are exclusive causes.
Each argument exhibits a distinct structural vulnerability. The Economics argument fallaciously transfers a characteristic of individual components to the entire system (Composition). The Linguistics argument treats phonetic correspondences, which are necessary to establish a common ancestor, as sufficient to guarantee it. The Policy argument attacks a proposal by citing the proponent's financial motives rather than addressing the merits of the rezoning (Ad Hominem). The Geophysics argument assumes that because iron deposits and meteorite impacts are sufficient to cause a magnetic anomaly, no other cause is possible, thus ruling out the meteorite impact and erroneously concluding an iron deposit must be present.
