TOPIC: ARGUMENT105 - The following appeared in a health newsletter.
"According to a recent study, people with many social ties report catching colds less often than do people with few social ties. Consequently, researchers conclude that having an active social life probably helps strengthen the immune system. The researchers note that catching a cold-one of a family of highly contagious viruses-gives the cold-sufferer temporary immunity to that virus in the future, but not to the many other related viruses. Merely being exposed to a new cold virus, however, is not enough for a person to catch a cold, since a strong immune system can successfully fight off some new viruses. Thus, in order to prevent catching a cold, people should strengthen their immune systems by becoming more active socially."

Grounding on a recent study, supporting that having an active social life can help strength the immune system, and then synthesizing the supporting with a conclusion about the relationship between catching a cold and the immune system, the arguer claims that in order to prevent catching a cold, we should attend more social activities. However, there are a lot of flaws in the argument.
Firstly, the reliability of the study are open to doubt. In the study, the data of how many people catching a cold is reported by the people themselves, so there is the possibility that the people who have lots of social activities are too busy to report when he catches a cold. Then the data is groundless to support any conclusion. Even if the data is accurate and convincing, there is still other factors can lead to the social people have fewer possible concerning catching a cold. For example there is possible that the social people do exercise in daily life or have a healthy habit which can prevent the cold virus from them. Granted that it is true that attending more social activities can avoid catching colds, but arguer fails to explain the relationship between strengthening the immune system and the decreasing occurrences of catching cold. There are also other possible reasons which can affect the occurrences of catching colds such as the weather changes and the air pollution. So it is too arbitrary to have the conclusion-having an active social life can help strength the immune system.
Moreover, the arguer bases on the research's conclusion that the cold is caused by not one kind cold virus, but many kinds of cold virus, get an unreasonable suggestion that we should prevent catching a cold by attending more social activities. Attending more activities means we need to meet more individuals which led to that we have more chances to be exposed to many kinds of cold virus and it is, obviously, unreasonable to prevent catching a cold in this way. What’s worse, this method might just have the opposite effect, improves the possibility about catching colds, on preventing catching a cold. It just.
In this argument the arguer falls to provide a complete and sensible study or research about whether there is a relationship between attending more social activities and immune system. In addition, there should be more appropriate evidence to support the arguer's conclusion instant of some reason which not only can't support the conclusion but also have a opposite effect. |
