The Fortune 500 survey, in contrast to the previously administrated 'business school students' survey, has higher trust and reliability due to several unique features. First, the survey had a sample size of several thousands of respondents. Second, the respondent population was based on executives, managers and experts belonging to different industry sectors, who were more knowledgeable on these matters in comparison to students. Third, the alteration in the respondent population over the years was more moderate in comparison to the prominent changes in the student population. These unique features of the Fortune survey made it more reliable in comparison to previous surveys (Chen, Fahr, and MacMillan, 1993).
