Argument51 提纲
实验设置的问题:
1、No evidences show the two group of guinea-pigs are identical or at least similar.
2、The two doctors who took charge of the experiment might have marked differences between their experience and qualification. And their individual therapies would make the effects of the treatment different.
3、The use of sugar pills might have a counteraction on the healing.
实验推论的问题:
The author cannot suggest all the patients take antibiotics according to the hypothesis that only part of patients to be related.//

In this newsletter excerpt, the author concludes that all patients who are diagnosed with muscle strain should take antibiotics as part of their treatment to help them heal quickly. To support this conclusion the author points out a hypothesis that secondary infections would have counteraction on the healing of these kinds of patients. The author also cites an experiment in two groups of patients, in which the group taking antibiotics heal faster than the other one. The author's argument is problematic in several respects, rending the argument unconvincing as it stands.
The argument's chief problem is that it relies on numerous unsubstantiated assumptions about the experiment. One such assumption is that the physiological conditions of the two groups of patients are identical or at least similar. Yet logic and common sense inform me that it is quite possible that one of the group suffer from more serious injuring. This may be the very reason that the progress of healing of this group is slower. In short, without considering the different physiological conditions, the author cannot justifiably conclude that the result of quicker healing is due to the effect of antibiotics.
Even if the extent of strain of two groups is equal, the scientific reliability of the experiment's results is questionable. There may be a wide gap between the two doctors who direct the experiment separately in their experience and qualification. The author does not provide any evidence to show the two therapies have same efficiency on patients. For example, Dr. Newland, a doctor who sepcialized in sports medicine, has more experience handling muscle stain and his therapy has been proved successful on many athletes. Meanwhile, Dr.Alton just graduated from university and has not treated any patients himself before. If it is the truth, the result of the experiment is ceitainly deducible.
Even if the two doctors have equal qualification and use the same therapy, one can not infer that antibiotics help the patients. I notice that in this experiment, the other group is given sugar pills as a psycological substitute. And no evidence explains the sugar pills would not have counteration on the muscle strain. Provided they will defer the healing of muscle strain, then the comparability in this experiment will be specious.
Aside from the problems involving the experiment, the author’s conclusion that secondary infections keep the patients from healing quickly is also unwarranted. While it still remains the state of hypothesis, the author has not sufficient reason to suggest all the patients of muscle strain take antibiotics as part of their treatment. There are lots of potential possibilities that interfere with the healing of this kind of strain. For those patients, it might be useless or even worse to take antibiotics.
In conclusion, the author’s argument is not persuasive. To bolster it he must provide clearer evidence that the experiment is designed on an objective and conclusive basis. Such evidence might include the following: a suvey proving that secondary infections are the primary reasons that keep the patients from healing; an observation report showing that the therapies of two doctors have the same efficiency; another experiment revealling sugar pills have no counteraction; and diagnosises from authorities that all the patients in the experiment have the strain of the same extent.

The author of this newsletter excerpt concludes that all patients suffering muscle strain should take antibioicts so that they can heal quickly. To support this conclusion, the author put forward a hypothesis about the interference from secondary infections on severe muscle strain. He also cites an experiment to evidence the antibioicts would have efficiency to this kind of circumstance. However, this argument is problematic in several logic respects, rending the argument unconvincing as it stands.
The chief problem in this argument is that the hypothesis as a prerequisite stated in the begining is insufficient to deduce the conclusion that all patients who are diagnosed with muscle strain would be well advised to take antibioicts. Firstly, one of significant conditions in the prerequisite comes up as it is secondary infections that might interfere with the treatment. Meanwhile, the author's conclusion obviously does not refer this piont; as a result, those patients not having any infections are included in the eventual recommendation. Secondly, the hypothesis also mentions just part of patients having secondary infections heal slowly. But the author arbitrarily enlarges the scope of the patients who may take the related treatment without any explanations. Furthermore, the author overlooks the fact that such phenomenon only occurs after severe muscle strain. In short, the author draws a conclusion that is broader in scope than is warranted by the prerequisite advanced, for all the three factors above are omitted in his final conclusion.
Aside from the problems invoving the prerequisite, the experiment sopporting the prerequisite is also unsound, for it relies on numerous unsubstantiated assumptions. One such assumption is that the physiological conditions of the two groups are identical or at least similar. Yet logic and common sense inform me that it is entirely possible that one of the group suffer from more serious injury. This may be the very reason that the progress of healing of this group is slower. On the other hand, the author even does not provide any evidence to show the therapies those two doctors using have the same efficiency, not to mention the potential counteraction from sugar pills.
In conclusion, the author’s argument is not persuasive. To bolster it he must provide clearer evidence that the experiment is designed on an objective and conclusive basis. Which is more crucial is that more detailed diagnosises should be exhibited including all kinds of features in different stages of most patients’ therapeutic processes.
撇开路数的新尝试,但是写完看看觉得例证显得很草率,不知道这样的文章在实战中会不会分数很低?
