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.'
------正文------
Merely based on a series of unwarranted assumption and dubious evidences, the arguer comes to the conclusion that the use of Ichthaid can reduce the absenteeism in our schools and workplaces, it also can prevent colds. On the surface, the argument appears to be somewhat logical, actually, however, the argument does not provides compelling support making the argument sound and suffer from several critical flaws as follows.
To begin with, the arguer asserts the colds are most usually reason for absences from school and work and the lower rate of absenteeism will occurs follow the colds heavily reduction . But the argument has not any evidence to support this connection, it is completely possible that the colds is just the excuse for people to leave, the actual reasons perhaps are involved in tiresome, fatigue and laziness, so, even though the colds are well prevented, the people will say they have a pain on the leg, they suffer from a sever headache, and so forth, accordingly, they are still unlikely to go to school and work.
In addition, another flaw the arguer made lies in the relationship between fish consumption and the times go to doctor to treat colds. Is it really useful to reduce the frequency of cold by eating highly fish? I almost eat fish everyday, but I still need to visit doctors for cold! Is it not just a custom for East Meria? Furthermore, the less times to go to hospital does not mean the less times to catch a cold, perhaps most of the people catching a cold want to deal with it at home to save money, perhaps they want to go to hospital, but the busy work make it impossible, also perhaps they know this cold will not do much business with his or her healthy, in order to present they are still ill so that need not to work and study, they are deliberate not to treat it in hospital . In a word, the argument does not contain sufficient indication to arrive the conclusion that eating a great deal of fish will reduce the rate of cold.
Even though the highly eating fish can prevent cold in East Meria, the same result will not exist in the West Meria. Different places have different corporeity, maybe the people in West Meria is sensitive to fish, they will become more vulnerable result from eating fish, and finally more easy to be cold.
Last but not least, the arguer suggests that people should use a substance called Ichthaid everyday, since this matter derived from fish oil. Though it is true that eating fish will prevent colds, but it does not imply the fish oil has equal efficacy to treat cold. Perhaps it is very the fish oil that do harm for preventing colds. Without a careful examination, we can not accept the arguer's recommendation; after all, it is relative to our health.
In summary, this argument is not persuasive as is stands, to making it more convincing , the arguer should provide more information about the real reason for absence and some results of research on the fish concerning its constitutes and what the function of each constitutes of fish.. |
