This is a flawed question, and we know this because of the question stem: Which one of the following, if true, indicates the most serious flaw in the method used by the investigators?
The stimulus is recapping a TV program about astrology, where they found 20 people who were Geminis and would be willing to go on TV for an interview and take a personality test. The test confirmed that these people were more extroverted and social than the average person. Therefore, the argument concludes that the investigation supports the view that birth signs affect personality. The argument is assuming that all Gemini is outgoing and social, but since they only pick Gemini who would be willing to go on TV, it’s sort of a pre-selected group. After all, if someone was more introverted they’d be less willing to agree to be interviewed, regardless of their sign. There is a correlative-causal flaw here, and the argument makes an invalid and hasty conclusion based on a group they selected that would confirm their conclusion. The way they selected their data points gave them a false positive.
Answer Choice (A) is not the flaw; who gave and scored the test has nothing to do with the way this argument is flawed.
Answer Choice (B) also does not indicate the flaw; in fact, this could in some ways strengthen the argument.
Answer Choice (C) describes what’s happening in the stimulus, but it doesn’t point out what's wrong with the argument.
Answer Choice (D) also does not point out a flaw in the argument: an abundance or dearth of Gemini does nothing to point out the flaw in our answer.
Correct Answer Choice (E) points out the flaw perfectly. What if the study just completely ignores the Gemini because they don’t want to participate in the first place?
