Flawed ReasoningDiff: Medium
Logic Breakdown
Passage Summary: An ad claims that because some people have driven their cars for a huge number of miles, your new car is guaranteed to do the same.
Conclusion: Any individual who purchases a Sturdimade can be certain that the car will last for a very long time.
Reasoning: There is a club of hundreds of owners who have successfully driven their Sturdimades for over 100,000 miles.
Analysis: This ad is a bit like saying that because some people win the lottery, buying a ticket is a reliable way to get rich. It highlights the long distance club members but stays silent about the thousands of Sturdimades that might be sitting in scrap heaps after only 20,000 miles. The flaw lies in using an exceptional group of survivors to make a promise about the average experience. Look for an answer that points out the sample of club members is not representative of all Sturdimade owners.
