70. The following appeared in a memorandum from the president of a company that makes shampoo.
“A widely publicized study claims that HR2, a chemical compound in our shampoo, can contribute to hair loss after prolonged u. This study, however, involved only 500 subjects. Furthermore, we have received no complaints from our customers during the past year, and some of our competitors actually u more HR2 per bottle of shampoo than we do. Therefore, we do not need to consider replacing the HR2 in our shampoo with a more expensive alternative.”
生产香波的公司的主席的备忘录：
一份广泛出版的研究声称HR2，我们的香波里的一种化合物，长期使用后可能导致脱发。但是，这项研究只包括500个样本。此外，过去的一年里我们并未从我们的顾客那里接到投诉，而且一些我们的竞争者在一瓶香波里使用的HR2比我们的还要多。因此，我们不必考虑用更贵的替代物替代我们的香波里的HR2。
The president of the company that produces Glabrous Shampoo argues against removing the ingredient HR2 from the shampoo even though a scientific study claims that prolonged u of HR2 can contribute to hair loss. Three reasons are cited as the basis for this decision. First, it is argued that since the scientific study involved only 500 subjects, it can be disregarded. Second, none of Glabrous’ customers have complained of problems during the past year. And, finally, Glabrous’ competitors u more HR2 per bottle than Glabrous. The president’s decision is problematic in veral respects.
To begin with, the fact that the scientific study on HR2 involved only 500 subjects is insufficient grounds to dismiss the results of that study. If the subjects for the study were randomly chon and reprent a diver cross ction of the population of shampoo urs, the results will be reliable regardless of the number of participants.
Next, the scientific study determined that prolonged u could contribute to hair loss. While “prolonged u” was not defined in the memorandum, the fact that none of Glabrous’ customers have complained of problems during the past year is not a reliable reason to believe that problems will not ari in the future.
Finally, the fact that Glabrous’ competitors u more HR2 in their products than Glabrous us is irrelevant to the question of whether Glabrous should remove HR2 from its product. Moreover, rather than providing a reason for not removing the compound, this fact rves better as a reason for doing so. By removing HR2 from its product Glabrous could gain an edge over its competitors.
