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." 论点:用Ichthaid-----一种渔油中提取的营养物质可以防止感冒和降低缺勤.
论据:1.一项调查表明,East Meria的人每年因感冒只看一次医生, 而且那儿的鱼销售量高.
2.感冒是缺勤的最常见原因
错误:1.无效调查:未知方式/组织者/样本数量, 而且调查内容值得质疑,人们很有可能有很高的感冒率但在家中自己吃药解决而不去看医生.
2.就算调查有效,感冒率低,但与吃鱼多有关吗?没有任何证据表明吃鱼能防止感冒.很有可能是那里人喜欢吃鱼.
3.即使以上假设都成立,但缺席率真的与感冒有关吗?不排除感冒只是很多人不来上班或上学的一个借口。而且在EAST运用的方法适用于WEST吗?Ichthaid 真的有效吗?
