TOPIC: ARGUMENT38 - The following memo appeared in the newsletter of the West Meria Public Health Council.
"An innovative treatment has come to our attention that promises to significantly reduce absenteeism in our schools and workplaces. A study reports that in nearby East Meria, where fish consumption is very high, people visit the doctor only once or twice per year for the treatment of colds. Clearly, eating a substantial amount of fish can prevent colds. Since colds are the reason most frequently given for absences from school and work, we recommend the daily use of Ichthaid, a nutritional supplement derived from fish oil, as a good way to prevent colds and lower absenteeism."
In the memo presented above, the author claims that using Ichthaid, a nutritional supplement everyday can prevent colds, therefore can prevent colds and lower absenteeism. To support the recommendation, the author cites a study report that in nearby East Meria, people eat a lot of fish, therefore, they visit the doctor only once or twice every year for treating colds.
However, close scrutiny reveals that the argument suffers from several logical fallaties as it stands.
To begin with, the author points out that colds are the reason most frequently uesd by workers and students for absences from work and school. However, the author fails to provide any strong evidence to prove this. As it is known to all, falling ill is one of the most excuses used for absenteeism, and cold is one of the most common illnesses that can caught by anyone. It is very likely, therefore, that students and workers who are using colds as the reason for absences are actually healthy. Colds are just excuses used for taking leaves from work or school.
Secondly, the author assumes that people in East Meria merely visit doctor for treatment of cold due to the fact that fish consumption is very high in East Meria. Again, the author does not provide clearly evidence to support this assumption. Eating a lot of fish may have no correlation with the fact that people seldom visit the doctor because of colds, not mentioning a casual relationship. Besides, it is entirely possible that people in East Meria prefer to by over-the-count medicine instead of visiting the doctor. Or else, people using other supplement for preventing colds. To the extent that either is the case, the author cannot convince me the high level fish consumption is the reason for not catching colds.
Last but not least, the recommendation reached by the author that taking Ichthaid daily has the same effect as eating a substantial amount of fish is also ungrounded according to the memo. Even if conceding eating a substantial amount of fish is the very reason for catching less colds, unless the author demonstrates that Ichthaid has the same effect as fish for preventing cold, we cannot consider the memo as persuasive.
To sum up, the author makes a unreliable recommendation based on a groundless conclusion. To bolster the recommendation, the author must prove that eating a lot of fish is the reason that people in East Meria seldom visit the doctor for treatment of cold and Ichthaid actually has the same effect as fish for preventing colds. To better assess the argument, I need more information about the actual reason for people's absences form school and work. |
