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 concludes that Ichthaid, a nutritional supplement derived from fish oil, is an effective way to prevent colds and lower absenteeism. To support it, the arguer cites a study which reports that people in the nearby East Meria (EM) who consume much fish visit doctors fewer times than average leverlevel and argues that preventing colds can decrease the absenteeism of school and work. Through scrutiny I find this argument has several logical flaws which prevent it from convincing.
First, the arguer fails to prove the causal relationship between the high consumption of fish and the fewer times of visiting doctors for colds. Without further information of the body situation of people in ES and other circumstances of ES, it is entirely possible that it is the weather condition contributes to the high lever of the health situation of people in ES.是想说天气使大家身体状况很好,而不是fish?为了更有说服力一点,起码也要给出什么样的天气,比如正好ES全年气候温和... Or perhaps those citizens pay more attention of preventing colds than other people. Failing in ruling out these possibilities, the arguer cannot convince me that eating much fish can improve the ability to resist colds.
Second, even if eating fish truly attributes to fewer colds, no evidence shows that a nutritional supplement derived from fish oil can also decrease the colds. The arguer does not offer any information about the function of fish oil, so it is doubtful that it is the other part of fish but not fish oil which results in the less cold. Further, in the absence of particular function of Lchthaid, it is impossible for me to believe that Lchthaid dose not contains substances which are detrimental to human body.这层关系也递进的太快了点吧,你的结论是要说LCHTHAID不含有有益物质,而不是说有啊
Third, even assuming that Lchthaid can effectively decrease the cold and has little negative function, the arguer unfairly supposes that preventing colds successfully can lower absenteeism. Common sense tells me that the reasons for absence from work and school is often relevant to having colds, despite it is true or only a false excuse. 关系没看明白...In fact, decreasing colds can lower absenteeism is nothing but an illusion.
In sum, this argument is unpersuasive as it stands. To strengthen it, the arguer should provide more information of the life situation 建议用health condition of people in EM and prove that Lchthaid truly benefits health and reduce colds. Moreover, to further assess this argument, I would need to know that the conditions of the reasons of the absenteeism in West Meria. |
