argument 38
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 memo, the author recommends that daily use of Ichthaid will significantly reduce absenteeism in the schools and workplaces. To support the recommendation the author points out daily use of Ichthaid can prevent colds which are the chief reason for absences from school and work. Furthermore, the author also cited a study reported in nearby East Meria, where people merely visit doctors. At first glance, the argument seems very specific and convincing. A close inspection of it would reveal how flimsy it is.
In the first place, the argument assumes that the absenteeism in schools and workplaces is due to colds which are the reason most frequently given. However, the author provides not enough information to prove this claim. It is possible that they have days off in the name of catching colds. Even if they really catch colds, perhaps it is not serious at all, or at least not insofar as to keep them away from schooling or working. They may be delayed by some other factors. Without considering and ruling out these possibilities, the author can't reach to this conclusion.
In the second place, assuming that people in EM merely visit the doctor due to the high consuming of fish, the author hardly suffices to prove that the daily use of Ichthaid would prevent colds and lower absenteeism in West Meria Public Health Council(WM). There are several factors which render it unconvincing as it stands. Firstly, the author provides no evidence to substantiate people in EM merely visited the doctor for the treatment of colds due to the high consumption of fish. It is possible that the weather there is so warm and almost unchangeable that cold is unlikely to prevail. It is also possible that the education of avoiding colds is strengthened than ever before. Or perhaps it is due to other food rather than fish. Without considering and ruling out these and other possible facets, the author could not come to the conclusion that the high consumption of fish help preventing colds. Secondly, even if colds could be defended by eating fish, the situation in EM can not reflects that in WM. The climate in EM and WM probably quite different and the manners that people own are also varies from place to place. Therefore, the author can't equal WM with EM.
Finally, even if fish can help prevent colds, the author provides no such evidence to substantiate that Ichthaid also could helps to keep away from colds. Perhaps some other nutritional supplements derived from fish oil are effective while Ichthaid has only a little or even no effect on curing colds.
In sum, the author can't justify his or her recommendation that the daily use of Ichthaid would help to prevent colds. To bolster this recommendation the author must provide better evidence to convince me that it is the Ichthaid rather than some other ingredients that cures the colds. Furthermore, we need to the absenteeism is really due to colds instead of other possible illness. To better evaluate this recommendation, I also need to know that EM and WM share the same situation. |
