3.06Argument No.81
Allergies are an overreaction of the immune system to certain stimuli. One view is that allergies can develop as the result of childhood exposure to certain irritants, such as dust or animal dander, while the immune system is not yet mature. Another view is that exposure to particular bacteria early in childhood actually triggers the proper development of the immune system, and that limiting exposure to these bacteria through excessive hygiene can cause children's immune systems to overreact to certain irritants later on. A new study supports the second view: children who are washed especially frequently and whose parents clean their homes especially frequently are more likely to develop allergies than are other children. So in order to reduce the incidence of allergies in children and adults, parents should not limit children's exposure to irritants or bacteria.
The arguer claims in the memo that it is not a mistake the XYZ Company replaces Delany with the cheaper Walsh Personnel Firm, offering with the comparison of Delany and Walsh and the statistics when the company used Walsh. However, there are a few logical mistakes in it, some of which I would point out below.
To begin with, the argument unfairly suggests that Delany is superior than Walsh, as Delany has bigger staff larger, number of branch offices, and the less average time their clients find jobs. It is totally possible that Walsh devotes more money on their staff's salaries or clients instead of offices, and clients of Walsh who pay more would expect a better job, resulting in a longer time for seeking. Without other concrete evidence about how well these companies help their clients find jobs, or how many clients these company have, the conclusion that Walsh is inferior to Delany is not persuasive.
In addition, to strengthen the effectiveness of Delany, the argument present that employees who get Delany's help found jobs more quickly than others last year. However, only one year, which is a short period, cannot provide sufficient evidence the of Delany's effectiveness. Maybe last year, many companies were facing staff shortage, leading to quicker job findings, while in other times, employees will have difficulties finding suitable jobs. Therefore, the author should provide a long period of result about Delany's help, to further substantiate the statement.
Moreover, the arguer supports his/her statement by vaguely supplying some ambiguous evidence. From the memo, the employees only find a job more quickly with the assistance of Delany, and half of the employees who lay off find a job within a year when Walsh was helping. The arguer fails to provide exact statistics when Delany is helping. Perhaps, almost every employee finds a job with Walsh's help in one year, while other half people refused to take Walsh's help. On the other hand, Delany's help may be less effective by assisting them find a job in one year or more. In that case, either the company makes a mistake or it saves money by selecting Delany.
In conclusion, since no further statistics is provided to support the arguer, the statement of that it is not a mistake of choosing Delany is unconvincing. She/he should provide more detailed information about the comparison of two companies, as mentioned above, to persuade others.
