Logical Flaws

Read the argument below.

Legal Scholar: The proposed statutory framework for regulating artificial intelligence should be entirely rejected. A legislative mandate that attempts to codify ethical constraints on algorithmic decision-making is inherently invalid. We can be certain of this because any legal apparatus designed to restrict the autonomous outputs of machine learning systems inherently lacks legitimate jurisprudential standing.

Is the following statement about the argument true or false?

The legal scholar's argument is logically flawed because it offers a premise that is essentially a mere restatement of the conclusion it seeks to prove.

According to the established standards of rational inquiry, a theory is justified only if it is supported by a preponderance of empirical evidence. The striking workers claim that their decision to blockade the factory is justified because it is the only way to force management to the negotiating table and secure living wages. But this demonstrates a clear misunderstanding of rational inquiry. Since the workers have provided no empirical evidence to support their blockade, their claim that the blockade is justified is entirely without merit.

Which of the following most accurately describes a logical flaw in the argument's reasoning?

Each of the arguments below is vulnerable to criticism on the grounds that it illicitly shifts the meaning of a key term. Pair each flawed argument with the abstract description that most accurately diagnoses its specific equivocation.

Financial Columnist: In 2015, traditional brick-and-mortar retailers accounted for 80 percent of all retail corporate bankruptcies, while online-only retailers accounted for the remaining 20 percent. Since then, the total number of online-only retailers operating in the market has quadrupled. Last year, traditional brick-and-mortar retailers accounted for only 55 percent of all retail corporate bankruptcies, whereas online-only retailers accounted for 45 percent. It is clear from these figures that the financial stability of traditional brick-and-mortar retailers has improved since 2015, as they are now experiencing fewer bankruptcies annually than they did previously.

Which of the following most accurately describes a flaw in the financial columnist's reasoning?

Sociologist: A society can only be considered free if its citizens are not subject to systemic coercion. As modern neuroscience has demonstrated, every human action is the inevitable result of prior neurological states governed by inflexible natural laws. Since our actions are dictated by these inescapable natural laws, they are completely determined by forces outside our control. Thus, we are constantly subject to systemic coercion. Therefore, no human society can truly be considered free.

Which of the following accurately describe a logical flaw in the sociologist's reasoning? Select all that apply.

City Council Member: Over the past fifteen years, our city's transition to using a new synthetic asphalt binder has directly caused a steady decrease in our annual road maintenance costs. Since we plan to continue using this synthetic binder exclusively, we can confidently project that our annual road maintenance costs will continue to decrease over the next ten years.

Which one of the following most accurately describes a flaw in the city council member's reasoning?

Analyze the following arguments drawn from various corporate and public policy contexts. Pair each argument with the abstract description that most accurately identifies its specific error in reasoning regarding numbers and percentages.

Medical researcher: When evaluated against a placebo in our most recent large-scale trial, the experimental allergy medication reduced the frequency of symptomatic episodes by a statistically significant margin. Therefore, health professionals should recommend this medication as a replacement for current over-the-counter treatments, because patients will obviously benefit from experiencing such a significant improvement in their daily routines.

Which one of the following most accurately describes a flaw in the medical researcher's reasoning?

Analyze the four brief arguments below. Pair each argument with the abstract description that best characterizes its flaw in reasoning regarding numerical or proportional evidence.

Financial Analyst: In 2021, investments in renewable energy startups accounted for 22 percent of all venture capital funding deployed in the energy sector. By 2025, that figure had dropped to 14 percent. Conversely, the share of energy sector venture funding going to traditional fossil fuel companies rose from 8 percent to 15 percent over the same period. This proportional shift demonstrates a change in investor focus. Therefore, it is clear that venture capitalists are funneling a smaller absolute amount of money into renewable energy startups today than they were in 2021.

Which of the following most accurately describes a flaw in the financial analyst's reasoning?

Software Executive: Over the past three years, the percentage of our company's total revenue generated by mobile applications has steadily declined. In contrast, the percentage of our total revenue generated by enterprise software has grown. Therefore, it is clear that our mobile applications are bringing in less money than they did three years ago.

Which one of the following most accurately describes a flaw in the software executive's reasoning?

Mayor: The historical preservation board claims we should not approve the new skyscraper because it would destroy the unique character of the downtown district. However, building this skyscraper requires a massive collaborative effort, a commitment to overcoming immense engineering challenges, and a dedication to improving our city's future. These are all qualities that undeniably build strong character. Thus, the board is mistaken; the skyscraper project will actually enhance, not destroy, character.

The reasoning in the mayor's argument is most vulnerable to criticism on the grounds that the argument...

Industry Analyst: In $2024$, software engineers accounted for $45\%$ of all new hires at major tech firms, while product managers accounted for $25\%$. In $2025$, software engineers accounted for $55\%$ of all new hires at these same firms, and product managers accounted for $15\%$. Clearly, these firms hired a greater total number of software engineers and a smaller total number of product managers in $2025$ than they did in $2024$.

The analyst's conclusion depends on assuming which of the following? Select all that apply.

The reasoning in each of the short arguments below is flawed due to the uncertain use of a key term or phrase. Select the precise abstract description from the right column that accurately characterizes the semantic shift occurring in each argument.

Match each of the following flawed arguments to the abstract description that most accurately identifies its reasoning error concerning percentages and absolute numbers.

Public Health Official: Ten years ago, asthma cases represented $8\%$ of all respiratory-related emergency room visits in our county. Last year, asthma cases represented $18\%$ of all respiratory-related emergency room visits. Clearly, a greater number of people in our county are suffering from severe asthma attacks requiring emergency care than a decade ago.

Which of the following most accurately describes a flaw in the public health official's reasoning?

Consider the following argument:

'Technological optimists argue that artificial intelligence will solve our most pressing economic inequalities by creating unprecedented abundance. However, historically, major technological shifts have always temporarily displaced workers and widened wealth gaps before new economic structures could distribute the benefits. Since we cannot afford another period of extreme wealth polarization, we must heavily restrict the deployment of advanced AI systems.'

This argument's reasoning is flawed primarily because it presumes, without providing justification, that heavily restricting advanced AI systems is the only way to prevent extreme wealth polarization during this technological transition.

Mayor: Our municipality is facing a critical energy shortage and must rapidly increase its power generation capacity. Critics oppose the construction of a new nuclear power facility, citing safety concerns and the high cost of waste disposal. However, if we do not construct the nuclear facility, we will be forced to rely exclusively on imported fossil fuels, which will drastically increase our greenhouse gas emissions and violate our climate commitments. Therefore, the critics are wrong, and we must proceed with the nuclear facility.

Which of the following most accurately describes a logical flaw in the mayor's argument?

Each of the following arguments relies on a flawed assumption that artificially restricts the available possibilities. Which critique accurately describes the specific false dichotomy committed in each argument?

Director: To adequately secure our planetary defense network, we must reallocate 15 percent of the agency's current satellite development funds away from deep-space exploratory probes and dedicate that capital entirely to near-Earth asteroid detection systems. Unidentified near-Earth objects currently represent the most immediate existential threat to our planet.

Astrophysicist: That is a catastrophically short-sighted policy. If we abandon all deep-space research, our technological edge in interstellar navigation will collapse, and our quest to understand the origins of the universe will be permanently halted.

Which of the following statements accurately describe how the astrophysicist's response distorts the director's initial argument? Select all that apply.
