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."

Based on a series of illogical assumptions and an unreliable study, the author finally draws an astonishing and unsubstantiated recommendation that daily use of Ichthaid (short for I) could be the useful way to reduce the colds and consequently absenteeism. After close scrutiny, several critical flaws have been found, which weaken the reliability of the author' recommendation.
To begin with, a threshold problem of this argument is the reliability of this study which the author's recommendation based on. No evidence is shown to us about the way of the study, and therefore we have good reasons to doubt: if the number of the samples enough to represent the whole group of people in East Meria? Moreover, even assuming that people in that district do visit doctors very little times for colds, it does not necessarily mean that it is fish which could be the main aspect to prevent colds. Entirely possibly people there has a tradition to cure some simple diseases such as colds themselves by just taking medicine, which will of course render fish no use to colds, which counters the author's recommendation.
Moreover, given that fish could be a proper way to cure colds, which, of course, is just an unacceptable assumption, it does not follow that the condition of absenteeism could be improved. It is highly possible that the main reason of absenteeism is just the students or workers want to sleep more an hour in the morning, in that case, colds will turn out to be just an excuse to absenteeism, which will surely make the author's recommendation unsound.
Admittedly, even if fish could be a useful avenue to colds and absenteeism, it does not amount to that I has the same function. The author gives the recommendation on the insubstantial hint that I is just the essence of fish which contributes to the function for people to recover from colds, which in fact lacks evidence and statistics. The fact that I is a nutritional supplement from fish oil can not diminish the possibility that I is just only a kind of normal element involved in fish, which has no influence on preventing colds at all.
To sum up, the author has probably drawn an unsettled or even misleading recommendation to reduce colds and solve the problem of lower absenteeism without further investigation on the relationship between fish and preventing colds and in-depth experiments on the assertion that I will surely do good to solve the same problem. |
