Zorluk: OrtaCorrelation vs. Causation

Geochemists analyzing sediment layers from the late Cretaceous period discovered a strong correlation: rock layers containing unusually high concentrations of the element iridium almost always contain vast amounts of fossilized fungal spores. Based on this observation, the geochemists concluded that the presence of high levels of iridium in soil creates an environment that directly promotes fungal proliferation.

The reasoning in the geochemists' argument is most vulnerable to criticism on the grounds that it

  1. A
    fails to distinguish between the absolute quantity of fungal spores and the percentage of those spores within the sediment
  2. B
    confuses a condition that is necessary for a phenomenon to occur with a condition that is sufficient for it to occur
  3. takes for granted that one phenomenon is the cause of another simply because the two phenomena frequently occur togetherCevap
  4. D
    infers that a characteristic of a specific sediment layer is representative of the geological period as a whole
  5. E
    relies on an assumption about the biological requirements of ancient fungi that cannot be verified by geological records

Cevap

The correct answer identifies that the argument takes for granted that one phenomenon is the cause of another simply because the two phenomena frequently occur together.
The argument's fundamental error is concluding that iridium causes fungal growth merely because the two are found together in the same rock layers. It fails to consider that a third factor (such as a catastrophic event, like an asteroid impact) might have caused both the iridium deposition and an environment full of decaying matter that encouraged fungal growth. The correct answer accurately abstracts this logical flaw.

Adım Adım Çözüm

1
Analyze the premises of the argument.
The premise establishes a strong statistical correlation: high iridium concentrations and vast amounts of fossilized fungal spores are frequently found together in the same sediment layers.
Identifying the foundational evidence is the first step in evaluating the argument's logical structure.
2
Identify the argument's conclusion.
The conclusion claims that the presence of high levels of iridium directly promotes fungal proliferation (a causal relationship).
The conclusion reveals the author's main point and how they interpreted the evidence.
3
Evaluate the logical gap between the premise and the conclusion.
The argument jumps from a mere correlation (things happening together) to a definitive causal claim (one thing causes the other), ignoring alternative explanations such as a third factor causing both phenomena.
Finding the logical leap exposes the core vulnerability or flaw in the reasoning.
4
Select the option that accurately describes this structural gap.
The option stating that the argument assumes causation simply because two phenomena frequently occur together perfectly matches the observed flaw.
The correct answer to a Flaw question must accurately abstract and describe the specific logical error committed in the stimulus.
