38The 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 recommends that in order to reduce the absenteeism significantly in schools and workplaces, people need to use Ichthaid daily to prevent colds. To substantiate this claim, the author provide a report showing that people in nearby East Meria visit doctor due to cold few time per year because they eat a large amount of fish. It seems to be a meticulous plan to solve the problem about attendance rate in East Meria, while a close examination would reveal how groundless it is.
To begin with, the author has analyzed the report with a logical false: fewer people to visiting doctor lesser time per year for treatment of cold neither makes sense for better health condition of people, nor decline to absenteeism. Inasmuch, the author fails to offer any information about the data of attendance rate circumstance in the investigated area. It might be entirely possible that due to other symptoms of illness, people living in nearby East Meria seek medical advice more times per year than people in East Meria. That is to say, people in nearby East Meria attend school and work at a low rate too.
Even assuming that the lesser cold patients means a better situation of people’s health, the author still cannot prove the causality between the two facts that more consumption for fish and fewer cold patients. There may be some possibilities that people in nearby East Meria enthuse over doing exercises to strengthen their immunity to the virus of cold, and that they perhaps prefer to have medicine by themselves rather than ask for a doctor when they got a cold. Thus, the author would only conduct nothing but fallacies, if he or she ignores the varieties of respects that may lead to the fewer visitors for treatment of cold.
Ultimately, even if eating much more fish would reduce the probability of catching cold, there is no evidence to convince that the enabling of preventing contributes to Inchthaid. Maybe, another ingredient from fish is the gold remedy for immunity to cold virus. Therefore, to improve the efficiency, the author must consider all kinds of supplements derived from fish that may induce a stronger immunity.
As it stands, the argument is not well reasoned. To make it more logically acceptable, the author would have to demonstrate more detailed investigations with solid fact and appropriate deductions. Such as, how about the situation of attendance rate in nearby East Meria, the evidence to definitely improve the causality between more ate fish and stronger immunity to cold virus and what is the specific ingredient leading to the immunity.
