This argument states that in order to improve profits, all of the cheese stores should discontinue stocking lots of varieties of imported cheese and concentrate primarily on domestic cheeses. The author cites the fact that LAST year's five best-selling cheeses at our NEWEST store were all domestic cheddar cheeses FROM Wisconsin, and a survey to point that an increasing preference for domestic cheese among ITS subscribers. With my reflection, I find this argument is flawed in several aspects as those words with capital letters shows, and I will discuss them in turn.
First of all, it is insufficient from the fact of the best-selling cheeses to conclude that the recommendation is feasible. In the first, it is the last year's situation, and the kinds of best-selling cheeses can change every year. Maybe this year they would be imported cheeses, thus stopping to stock those cheeses would cause loss for the stores. In the second, it is the situation of the newest store, which cannot apply to those old stores. It is possible that the old store's customers prefer the imported cheeses, and old stores take a major part of the stores, then imported cheeses are still share most part of the cheeses market. In the third and last, it happened according to the argument only in Wisconsin, we are not informed any information of other states' situation, while the stores located all nations, so the recommendation which involved all of the stores is untenable.
Secondly, the author cites a survey which operated by Cheeses of the World magazine shows an increasing preference for domestic cheeses among its subscribers. However, this survey lends little support to the author's recommendation. We are not sure how many people subscribe for this survey. Maybe it is not a popular magazine, and there are a few of people take part in the survey, and then the result is unpersuasive. Without more information and detailed description of the survey, I cannot be convinced as the recommendation stands.
To sum up, this argument is questionable as discussion showed above. To improve it, the author should think about other more tenable evidence, and provide more information about the survey.
