Gre Argument While it may seem logical at first glance that a business who wants to prosper should hire only people with little sleep, the author’s argument appears arguable with holes and potential assumptions that might prevent the argument from being effective, and thus not strong enough to lead to the conclusion.A number of assumptions have been made about the generalisability of the survey result, the reliability of the reported need of sleep and other related issues. To begin with, the 300 executives claimed that they need little sleep as reported in the survey did not necessarily indicate that all the executives acutually need little sleep. In other words, the assumption is that the subjects were telling the truth about their lifestyles during the survey. The reliability of reported data depends on whether the respondents provided forthright/ authentic/ accurate answers. It is possible that the survey respondents just want to impress others or show their attitudes towards sleep when answering the questions. Without exploring alternative scenarios or possibilities to verify the reliability of the survey results, it is not reasonable to apply the finding in the hiring processes. In addition, the author fails to rule out the possibility that the fast growth and heavy business of those firms prevent their executives from getting more sleep. Chances are that the fast growth of the business render the executives to work day and night. The executives, who rely on their job to make a living, might sleep little under the pressure involuntarily. Also, people who sleep more may have other characteristics which are necessary for a business to prosper. To be specific, workers can be divided into two groups——those who do repetitive basic jobs and those who do jobs with creativity. For the former ones, they must have to work long-period if the firm is keeping developing. For the later ones, their effectiveness depends on the newly-created blue print that might come into being by chance. Thus, more sleep and good relax can possibly keep the later ones to have their brain operate more actively, leading to more originility to be brought about. Beyond that, the assumption that the survey results can be applied more broadly may not hold true. Although the recent study might be true that the average numbered of hours the advertising executives need have close relation to the success of advertising company, this is not true of every individual in the all other fields.
