Zorluk: ZorWeaken

Consider the following argument:

Organizational Psychologist: In an initiative to curtail administrative burnout, a regional hospital network automated its patient intake record-keeping across half of its clinics, while the remaining clinics retained manual data entry. Over the subsequent eighteen months, clinicians at clinics with automated intake reported a 40 percent reduction in administrative fatigue, whereas clinicians at manual clinics reported no change. Thus, automating patient intake records is an effective method for reducing clinician administrative fatigue.

Evaluate whether the following statement is true or false:

The psychologist's conclusion is substantially undermined if, concurrent with the trial period, the hospital network systematically reassigned the most complex, documentation-intensive chronic care patients exclusively to the clinics retaining manual intake.

Cevap: Cevap

Cevap

True
The evaluated statement is correct in asserting that the argument is substantially weakened. The psychologist infers a direct causal relationship between intake automation and reduced clinician fatigue from a comparative study between automated and manual clinics. However, if the hospital network simultaneously shifted the most documentation-heavy cases away from automated clinics and into manual clinics, the automated clinics experienced an inherent decrease in overall paperwork demands independent of the software. This introduces a major confounding factor that explains the survey results without requiring the software to be effective, thereby undermining the author's causal claim.

Adım Adım Çözüm

1
Deconstruct the stimulus argument into premises and main conclusion
Premise: Automated clinics saw a 40% reduction in fatigue, while manual clinics saw 0%. Conclusion: Automating patient intake is effective at reducing clinician administrative fatigue.
Isolating the core causal claim is essential for evaluating potential vulnerabilities in the reasoning.
2
Identify the unstated causal assumption in the argument
The author assumes that the two groups of clinics were comparable in all other respects affecting administrative workload and that no confounding variable accounts for the observed drop in fatigue.
Causal arguments rely on the assumption that alternative explanations and confounding differences between comparison groups have been ruled out.
3
Evaluate the impact of the supplementary fact on the causal claim
Reassigning complex, documentation-heavy patients exclusively to manual clinics means the automated clinics had a lighter paperwork burden regardless of software efficiency, presenting a viable alternative cause for their reduced fatigue.
Providing a strong rival explanation for the observed outcome directly weakens a causal conclusion.
4
Determine the truth value of the evaluation statement
Because the supplementary fact demonstrates a classic confounding variable flaw and weakens the conclusion, the statement asserting that it substantially undermines the argument is True.
Matching the weakening effect to the statement's claim confirms its validity.
