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 this argument, the author fails to prove the causal relation between the daily use of Ichthaid(I) and the prevention of colds and the decrease of absenteeism, thus making the author's recommendation that to use I to prevent colds and lower absenteeism totally untenable. I will discuss the fallacies in turn.
To begin with, the author assumes the correlation between the high fish consumption and the fact that people visit the doctor less frequently for colds as a casual relation. However, no evidence is offered to show that the less frequency of colds is the result of the high fish consumption. It is quite possible that people here prefer exercises. More exercises in daily life will build up one's body, thus preventing him from many illnesses such as cold. For that matter, the fewer occurrences of colds has nothing to do with the high fish consumption.
In addition, the author does not consider the possible passive impact of high fish consumption. No other diseases apart from colds is mentioned in this argument, thus leaving open the possibility that there is a high incidence of other illness such as stroke, which is much more serious that colds. And this might be caused by the too high consumption of fish. No mention of the occurrence of other diseases, we cannot be persuasive high fish consumption really do good to people's health.
Even eating more fish in daily life can be accepted as a reasonable way to prevent colds, it is unnecessary that the daily use of I can prevent of colds. I is derived from fish oil, and as we all know, many elements of fish will change during the procedure to extract. Perhaps it is those changed elements that means a lot to prevent colds, while has nothing to do fish oil, let alone I. If it is so, the recommendation of the daily use of I is quite poor advice.
Furthermore, the author assumes that the absenteeism in schools and workplaces is caused by colds. However, this is might not be the case. Catching cold can only be used as a pretext of people's laziness. In another word, they do not go to work or school just because they do not want to rather than they catch cold. If the inherent cause of absenteeism is not found out and solve, lower occurrence of colds will not remedy the absenteeism.
In sum, the argument is unwarranted as it stands. The author fails to take many key factors into account. If the author can provide more information about how the overall healthy conditions of people are improved by the high fish consumption and the real cause of people's absenteeism to schools and workplaces, as well as the positive impact on people's health made by I, the argument will be more persuasive. |
