Below are four debate exchanges, each containing a flawed response by the second speaker. Match each exchange to the precise description of the logical vulnerability committed in that response.
- Urban Planner: To increase housing availability, we should amend the zoning code to allow duplexes in neighborhoods currently restricted to single-family homes.
Resident: Your plan to mandate high-rise apartment complexes on every quiet suburban street will completely destroy the character of our town.The response mischaracterizes the opposing position by exaggerating its scope, thereby making it easier to attack. - Journalist: The proposed cybersecurity bill contains critical vulnerabilities that could allow unauthorized access to personal data.
Senator: The journalist criticizing my bill has no formal degree in computer science, so her assessment of the legislation's technical merits should be entirely disregarded.The response rejects a substantive claim by attacking a personal characteristic of the individual making the claim. - Consultant: The company is facing declining profits. We need to evaluate our current marketing strategy and consider updating our product line.
CEO: We must either double our current marketing budget immediately or declare bankruptcy. Since we do not have the capital to double the budget, we have to file for bankruptcy.The response inappropriately treats two extreme courses of action as though they are the only possible alternatives. - Biologist: Certain species of birds exhibit altruistic behavior, such as warning calls that put the caller at risk but save the flock.
Philosopher: True altruism requires a conscious moral choice to sacrifice for others. Since birds lack complex moral reasoning, their behavior cannot be altruistic.The response attempts to undermine an argument by relying on a shift in the meaning of a key term.
Answer
The Urban Planner/Resident exchange matches the mischaracterization of the opposing position (Straw Man); the Journalist/Senator exchange matches attacking a characteristic of the individual (Ad Hominem); the Consultant/CEO exchange matches treating two extreme courses as the only alternatives (False Dilemma); and the Biologist/Philosopher exchange matches relying on a shift in the meaning of a key term (Equivocation).
Each debate exchange exhibits a distinct, classic logical flaw. The Urban Planner/Resident dialogue is the defining example of a Straw Man, where the original premise is warped into an extreme version to facilitate an easy rebuttal. The other exchanges serve as contrasts, exhibiting an Ad Hominem (attacking the Journalist's credentials), a False Dilemma (CEO limiting options to two extremes), and Equivocation (Philosopher shifting the meaning of 'altruism').
