170. For the past five years, consumers in California have been willing to pay twice as much for oysters from the northeastern Atlantic Coast as for Gulf Coast oysters. This trend began shortly after harmful bacteria were found in a few raw Gulf Coast oysters. But scientists have now devised a process for killing the bacteria. Once consumers are made aware of the increased safety of Gulf Coast oysters, they are likely to be willing to pay as much for Gulf Coast as for northeastern Atlantic Coast oysters, and greater profits for Gulf Coast oyster producers will follow.
In this argument, the arguer concludes that consumers will be willing to pay as much for Gulf Coast as for northeastern Atlantic Coast oysters after the bacteria in the raw Gulf Coast oysters is killed. To substantiate the conclusion, the arguer employs several lines of reasoning. However, it suffers from a series of logical flaws, which render it unpersuasive as it stands.
First of all, the arguer unfairly assumes that the harmful bacteria which were found in a few raw Gulf Coast oysters have made the consumer be willing to pay twice as much for Atlantic Coast oysters as for Gulf Coast oysters. It is entirely possible that other factors have resulted in the difference between their prices. Perhaps, for example, compared with the Atlantic Coast oysters, Gulf Coast oysters are very common in California; in other words, the latter group may be quite easily available. Common sense tells us people are more likely to deem the unusual ones to be precious. Or perhaps, the Atlantic Coast oysters are actually far more delicious, which correspondingly contributes to their higher prices. Without ruling out these possibilities or others, the arguer cannot convince us that it is merely the bacteria have resulted in Gulf Coast oysters’ lower price.
Even though it is true that the harmful bacteria should be responsible for the Gulf Coast oysters’ lower price, it is far from the truth to say that consumers in California would switch back to Gulf Coast oysters once they know about the scientific discovery for killing the bacteria in oysters. As we all know, reputation is easy to destroy but hard to regain. Even aware of the recent devise to kill the bacteria, consumers very probably are still afraid of this problem. If they cast doubt on the effectiveness of such device, they would still not buy GC oysters. It may be a long time and need strenuous work to conciliate their fear.
Finally, even if I were to concede that the consumers would totally believe that the bacteria in the oysters have been cleared up, it cannot ensure that producers of Gulf Coast oysters will be able to gain greater profits. The arguer fails to rule out at least two possibilities. First, introducing the process for killing the bacteria in oysters might greatly increase the cost, and hence render the sales of Gulf Coast oyster producers profitless, even though they could be sold at a higher price. Another possibility is that, since the Gulf Coast oysters have regained their reputation, the Atlantic Coast oysters will take no advantage over the Gulf’s. In other words, it is highly likely that Atlantic Coast oysters’ price will fall to the level of Gulf’s. In this case, the Gulf will have no chance to sell their oysters at a higher price, not to mention to gain a greater profit.
To sum up, the conclusion lacks credibility because the evidence and assumption cited in the analysis does not lend strong support to what the arguer maintains. To strengthen the argument, the arguer would have to provide more evidence concerning the reasons for Gulf Coast oysters’ lower price. To make it logically acceptable, the arguer also has to demonstrate that killing bacteria can really result in a greater profit. All in all, the arguer must provide evidence to rule out all the above-mentioned possibilities that might weaken the argument.
