Summarize Argument: Phenomenon-Hypothesis
The researcher concludes that certain makes of car are more common in different regions of the nation. Why? Because the researcher hypothesized that if that conclusion was true, then many people would overestimate the national commonness of their own cars—and this was the very result found by a study, thus supporting the hypothesis.
Identify and Describe Flaw
The researcher concludes that a hypothesis is true based on evidence that supports that hypothesis. However, the hypothesis could still be false, because support for a hypothesis doesn’t guarantee that it’s true. The researcher doesn’t account for the possibility of alternative explanations for the result, for example.
A
The argument fails to estimate the likelihood that most subjects in the experiment did not know the actual statistics about how common their make of car is nationwide.
The likelihood that most of the study participants were unaware of the actual commonness of their make of car is irrelevant to the argument. The argument is about whether different cars are more common in different regions, not about people’s car stats knowledge.
B
The argument treats a result that supports a hypothesis as a result that proves a hypothesis.
The researcher concludes that a hypothesis is true merely based on a premise that supports the hypothesis. This is a flaw because a hypothesis can have some support and still be false, for example if the same evidence is consistent with multiple explanations.
C
The argument fails to take into account the possibility that the subject pool may come from a wide variety of geographical regions.
Whether or not the subject pool comes from a variety of regions isn’t relevant, because the argument’s evidence just depends on most participants overestimating how common their car is.
D
The argument attempts to draw its main conclusion from a set of premises that are mutually contradictory.
The researcher does not use any premises that contradict each other in this argument.
E
The argument applies a statistical generalization to a particular case to which it was not intended to apply.
The argument doesn’t apply a generalization to a particular case. It’s more that the researcher is trying to make a generalization about car distribution across the nation based on a different generalization about how common people think their make of car is.
