In the medical newsletter, the arguer proposes that all patients who are diagnosed with muscle strain should be well advised to take antibiotics as part of their treatment. In order to support his proposal the arguer points out that Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain. In addition, the arguer who took antibiotics regularly throughout their treatment healed more quickly than those in control group. In fact, the proposal contains some crucial logical flaws.
First of all, the selection of experiment group should be reasonable. Unfortunately, the arguer provides no information about that. On one hand we can find no evidence of the number of the patients enrolled in the experiment. Maybe, the number is too small, for example, every group only included 5 patients. In that case, an insufficiently large size makes the result of the experiment worthless. On the other hand, the arguer does not inform how these patients were selected. It is possible that the severity of the patients who took antibiotics regularly was not so much as those in control group. Without providing the information of those two aspects, the arguer can not make me take seriously his proposal.
Secondly, even if the selection of experiment group and control group is reasonable, the arguer fails to justify that antibiotics caused the group of patients who took it regularly to recover more quickly. In a successful experiment, except the factor which is researched, all factors should be same in experiment group and in control group, which were never brought to fruition. It is most likely that the patients in control suffered no secondary infections at all. In that case, obviously, antibiotics is not the determinant. Even if the patients in control group did suffer secondary infections, it is still possible that other factors, played a decisive role to render patients recover not so quickly as the patients taking antibiotics regularly. For example, the patients n experiment group undertook a series of physical exercise, but thouse in control group did not. Either foregoing scenario, if true, would cause the result of the example to make no sense as the evidence of the hypothesis .therefore, the result of the survey is dubious.
Last but not the least, assuming that antibiotics can make patients suffering from muscle strain recover more quickly, in other words, secondary infections may keep some patients from healing quickly after severe muscle strain. It is open to doubt that all patients who are diagnosed with muscle strain would take antibiotics. Simply, not every patient would suffer secondary infections after muscle strain, thus antibiotics is not necessary. Especially, if antibiotics gave some side effect, it can bring danger to the patients. In that case, patients will not only fail to recuperate quickly but also suffered new sick. Unfortunately, the experiment failed to exclude this possibility, which make its result not tenable.
In sum, the arguer fails to prove us the information about the selection of experiment group and control group, besides, he does not inform the procedure of the experiment, what's more, the arguer commits a fallacy of overgeneralization. With so many logical flaws, the arguer can not make any valuable proposal. |
