Zorluk: KolayEvaluating Reasoning Flaws

A recent survey of urban professionals found that individuals who drink green tea daily report significantly lower stress levels than those who do not drink green tea. Based on this finding, a health consultant concluded that drinking green tea directly causes a reduction in stress levels. Which of the following best describes the flaw in the health consultant's reasoning?

  1. It assumes that a correlation between green tea consumption and lower stress proves that green tea causes the reduction in stress.Cevap
  2. B
    It provides evidence that reinforces the link between green tea consumption and stress reduction.
  3. C
    It draws a broad conclusion about all healthy dietary habits based solely on green tea consumption.
  4. D
    It assumes without proof that survey respondents reported their stress levels accurately.
  5. E
    It relies on an unsupported assumption that green tea contains artificial stress-relieving additives.

Cevap

The argument flawedly assumes that because green tea consumption and lower stress occur together, green tea directly causes the lower stress levels.
The correct answer accurately points out that the author confuses correlation with causation. Merely observing that green tea drinkers have lower stress does not prove that green tea causes the reduced stress, as other factors (such as exercise or meditation habits) might be responsible.

Adım Adım Çözüm

1
Identify the argument's premises and conclusion.
Premise: Daily green tea drinkers report lower stress than non-tea drinkers. Conclusion: Drinking green tea directly causes lower stress.
Isolating the structure highlights the leap made between the premise evidence and the author's claim.
2
Evaluate the logical connection between the premise and conclusion.
The author observes a correlation (two things happening together) and immediately infers a direct cause-and-effect relationship.
Correlation alone does not prove causation; alternative explanations (e.g., green tea drinkers might have healthier overall lifestyles) could explain the lower stress.
3
Match the identified flaw to the correct choice.
The choice stating that the argument assumes correlation proves causation correctly describes this reasoning error.
This directly captures the argument's central vulnerability.
