argument 76

The following appeared as part of an article in a health and beauty magazine.

'A group of volunteers participated in a study of consumer responses to the new Luxess face cream. Every morning for a month, they washed their faces with mild soap and then applied Luxess. At the end of that month, most volunteers reported a marked improvement in the way their skin looked and felt. Thus it appears that Luxess is truly effective in improving the condition of facial skin.'

通过一个实验说明Luxess face cream 是好用的。
首先，这个实验的志愿者有多少人，性别比例，年龄结构是怎么样的，过去他们的皮肤是怎么样的，以前是否一直用其他品牌的face cream 都不得而知。
他们的洗脸的方法是先用 mild soap then face cream 这会引起疑问，到底是哪个起了主要作用？
最后，实验的时间是一个月，如果使用的时间再长，会出现问题吗？

(1) The test duration is not long enough to convince reader that Luxess face cream can improve the condition of facial skin.
(2) The author fails to rule out other possiblities that may lead to the improvement of the volunteer's skin in the one month period of study.
(3) How the volunteers are selected is not known, thus it is not warranted to claim that this kind of face cream can be beneficial to other people.
有些书上提到The volunteers may have misunderstanding about the condition of their facial skin.但是感觉是有点攻击事实了。

(1)首先实验是怎么进行的质的疑问，是不是self reports？ Poeple might just be led to respond with the expected answer.
实验对象的数量是不是够，是不是随机选取的？是否覆盖了不同性别，不同年龄，不同的生活方式的人？ 如果没有，那么会undermine its generalizability. be too timid to deny its effect
(2)improvment很可能是被实验者的心理因素，有可能过于主观，或者是不好意思be shy of presenting thier negative comments；需要专业、客观、科学的评价标准和手段进行估量。
（3）即使承认可能有一定的效果，但是不能急于将它归功于face cream, 同样可能是mild soap的作用；或者有可能他们使用了其他的护肤品，或者采用了其他的护理手段。
