Argument 17. (比较引论)
17The following appeared in a letter to the editor of the Walnut Grove town newspaper.
"Walnut Grove's town council has advocated switching from EZ Disposal (which has had the contract for trash collection services in Walnut Grove for the past ten years) to ABC Waste, because EZ recently raised its monthly fee from $2,000 to $2,500 a month, whereas ABC's fee is still $2,000. But the town council is mistaken; we should continue using EZ. EZ collects trash twice a week, while ABC collects only once. Moreover, EZ—which, like ABC, currently has a fleet of 20 trucks—has ordered additional trucks. Finally, EZ provides exceptional service: 80 percent of respondents to last year's town survey agreed that they were 'satisfied' with EZ's performance."
Outline:
1. assumption: Cost-effectiveness
1) times of serviceà reasonable increased price; quality of service
2) additional trucksà reasonable increased price; quality of service
2. survey à representative & valid
3. the fallacy of one-sidedness
Basing on the assumption that EZ reasonably enhances its monthly fee, and compared with ABC Waste, EZ Disposal could provide better trash collection services, the author concludes that Grove’s town council should continue using EZ. This argument is unconvincing for several reasons.
First of all, the argument tries to convince us that choosing EZ to provide trash collection services for the Walnut Grove town is a cost-effective solution, by citing several evidence concerning seemingly apparent advantages of EZ. However, the arguer fails to make readers know the actual needs of trash collection of the Walnut Grove town. What if collecting once a week and the original number of trucks ten years ago have already met the needs of the Walnut Grove town? What if with the increasing awareness of protecting their environment, the local W-G residents reduce producing garbage intentionally? If so, affording the increased monthly fees for trash collection services would be an inefficient financing. In this sense, either the fact that EZ collects trash twice—more than ABC does--or that EZ has ordered more trucks proves little in itself about which service would be a better choice for Walnut Grove.
In the second place, although the arguer also cites a lately survey to strengthen his conclusion, the mere fact that most respondents to the recent survey considered EZ’s service satisfactory provides little support to the author’s recommendation. On the contrary, before I can accept any recommendation based upon it, the survey must be shown to be more reliable. Specifically, the responses must be accurate, and the respondents must be statistically significant in number and representative of the overall W-G residents. Without evidence of the survey’s reliability, it is unlikely to draw any firm conclusion about a right choice of which company to provide better services.
Finally, the whole argument commits the fallacy of one-sidedness. It is unfair to argue in favor of the opinion that EZ will do a better job than ABC, on the basis of the above evidence only about EZ. It is entirely possible that ABC provides a better quality of service for its clients. It is also possible that ABC utilizes high-tech methods to dispose trashes more efficiently and protects residents’ health and environment from pollution in a better way. Without any information from the argument about the work conditions and service efficiency of ABC, the arguer cannot justify his recommendation of EZ over ABC.
In summary, to make readers convince of the recommendation that EZ would be a more sound choice than ABC to do the trash collection work for the W-G town, the author would have to provide evidence about ABC’s services. To strengthen the argument, the arguer still needs to make a thorough analysis of cost-benefit of the two trash collection companies.
