Zorluk: OrtaRuling Out Alternate Explanations (Defender)

A recent municipal review of urban residential areas revealed that neighborhoods with a higher density of community gardens have significantly lower rates of property crime. City planners concluded that the presence of community gardens must foster social cohesion and neighborhood watchfulness, which in turn actively deters criminal activity.

Determine whether the following statement regarding the argument is true or false: A necessary assumption of the city planners' reasoning is that neighborhoods with preexisting lower rates of property crime do not systematically attract more civic funding and volunteer resources for community garden projects than neighborhoods with higher crime rates.

Cevap: Cevap

Cevap

True
The correct answer is True because the argument infers a specific causal relationship (gardens cause low crime) directly from a correlation. For this causal conclusion to be valid, alternative explanations for the correlation must be ruled out. The statement successfully rules out the alternate explanation of reverse causality (that low crime causes the development of more gardens), acting as a logically necessary defender assumption.

Adım Adım Çözüm

1
Identify the argument's core components: the premise and the conclusion.
Premise: There is a correlation between high community garden density and low property crime. Conclusion: Community gardens actively deter criminal activity.
Deconstructing the argument isolates the gap between the evidence provided and the causal claim made.
2
Analyze the logical gap in the reasoning.
The argument assumes a direct causal relationship based solely on a correlation, leaving it vulnerable to alternative explanations such as reverse causality or third-variable confounders.
Recognizing the causal flaw is essential to identifying what assumptions must be made to defend the conclusion.
3
Apply the Negation Test to the proposed statement.
Negated statement: 'Neighborhoods with lower rates of property crime DO systematically attract more resources for gardens.' This alternative explanation destroys the conclusion that gardens cause the reduction in crime.
If the logical opposite of a candidate assumption undermines the conclusion, the original statement is a necessary defender assumption.
