TOPIC: ARGUMENT57 - The following appeared in a newsletter on nutrition and health.
"Although the multimineral Zorba pill was designed as a simple dietary supplement, a study of first-time ulcer patients who took Zorba suggests that Zorba actually helps prevent ulcers. The study showed that only 25 percent of those ulcer patients who took Zorba under a doctor's direction developed new ulcers, compared to a 75 percent recurrence rate among ulcer patients who did not take Zorba. Clearly, then, Zorba will be highly effective in preventing recurrent ulcers and if health experts inform the general public of this fact, many first-time ulcers can be prevented as well."

The argument suffers from several critical fallacies that makes is unconvincing and unbelievable. The result of the study is not persuasive enough to substantiate the effect of the multimineral Zorba (z) pill in preventing ulcers, let alone to lend strong support to his claim that taking this pill, many first-time ulcers can be prevented as well.
To start with, even the study tells us that only 1/4 of those ulcer patients who took z under a doctor's direction developed new ulcers, and 3/4 who did not take z recurred, we still have some reason to doubt about result. Firstly, there might exist some distinguished difference between those patients, some patients may be younger, healthier and stronger than the others, and even taking no z pills, they will recover quicker and won’t develop ulcers again after carefully taking care of themselves. Secondly, it is quite possible that those who developed new ulcers again failed to get rid of some bad habits and kept doing something bad for their health, such as smoking, careless dieting, drinking, all of which will enable them to develop new ulcers. Moreover, how soon does the ulcers recur is not told yet, if the 1/4 patients in the first group were reexamined in a year while those 3/4 of the group were reexamined in only a month, it is unfair to claim that the pill is useful in preventing recurrence ulcers.
Secondly, even we concede that z can really help some patients prevent recurrent ulcers; the study can not ensure us that the first-time ulcers can be prevented as well. The study can at best substantiate the assistant function of z in preventing the disease; in fact, it is not a main cure pill. It is possible that it is combination of some elements of z and other pill that take effect. If people take z pills alone, there would be no effect in preventing ulcers. What's more, there are some other influential factors may result in the disease. For example, if someone is always gloomy and in bad mood, he/she will be prone to get ulcers. In this case, any pill can never help. And further, sometimes, ulcer is passed down to a person's through his/her ancestors, which means the genes decided that it is unpreventable for the person to develop ulcers.
Finally, some other significant factors we are not informed of. For example, the safety of the pill as a cure in treatment has not been tested by health experts. Does the pill have some side effects? If it is not compatible with some other pills treating ulcers, it will raise some allergies even adverse reactions. Or is it expensive that most of the majority of people cannot afford to take them? There are lot of factors decide that whether the health experts should popularize it and if it will be widely used in treating ulcers.
In sum, the arguer fails to provide more detailed information about the pill, he does not tell us some basic condition of those patients either. Absence of these important information, we can not believe that the effect of the pill |
