Zorluk: ZorCorrelation vs. Causation

Historian: Records from the 18th century indicate that cities with a high number of public libraries also reported significantly higher rates of political unrest compared to cities with few or no public libraries. Clearly, the ideas disseminated through materials in these libraries fostered dissatisfaction with the government, thereby directly fueling political instability.

The reasoning in the historian's argument is most vulnerable to criticism on the grounds that the argument does which one of the following?

  1. A
    illogically presumes that if the dissemination of subversive ideas causes political instability, then all political instability must be caused by the dissemination of such ideas.
  2. fails to consider that the observed correlation may be entirely explained by a separate factor that caused both the establishment of public libraries and the occurrence of political unrest.Cevap
  3. C
    relies on historical records that may not have accurately documented the true extent of political unrest in cities without public libraries.
  4. D
    confuses the rate of political unrest in a city with the absolute number of political uprisings that occurred there.
  5. E
    mistakes the intermediate claim that ideas foster dissatisfaction for the ultimate conclusion that public libraries fuel political instability.

Cevap

The argument fails to consider that the observed correlation may be entirely explained by a separate factor that caused both the establishment of public libraries and the occurrence of political unrest.
The correct answer accurately diagnoses the fundamental error in the historian's argument: jumping from a correlation (libraries and unrest existing together) to a strict causal conclusion (libraries caused the unrest). By ignoring alternative explanations, specifically that a third, unstated factor might be responsible for both phenomena, the argument's reasoning is deeply flawed.

Adım Adım Çözüm

1
Analyze the argument's structure to identify the premises and the conclusion.
Premise: Cities with many public libraries had higher rates of political unrest. Conclusion: Libraries fostered dissatisfaction and directly fueled political instability.
Separating facts from the author's interpretation is necessary to find the logical gap.
2
Identify the logical leap between the premise and the conclusion.
The author jumps from an observation of two things happening together (correlation) to the claim that one caused the other (causation).
This is a classic flaw pattern on the LSAT.
3
Formulate potential alternative explanations for the relationship.
A third variable (like a rising, educated middle class or urbanization) could cause both the building of libraries and political unrest. Alternatively, the unrest could have caused people to build libraries (reverse causation).
Anticipating the specific manifestation of the causal flaw helps in evaluating the answer choices.
4
Evaluate the answer choices against the anticipated flaw.
The correct option explicitly describes the 'third variable' or 'common cause' vulnerability in the causal reasoning.
Selecting the answer choice that precisely describes the structural error in the argument.
