Abstract
The already diverse workforce in America is expected to diversify at an even greater rate over the next decade. Projected workforce changes include those of age, gender, and race. The recently passed Americans with Disabilities Act also ensures that a growing number of persons with diverse physical needs will enter the workforce. Data from Moroney and Reising (1992) provide some clear indications of the types of subjects currently used in human factors experiments. Not surprisingly, these subjects represent a range of persons that is much less narrow than the range represented in the current and projected workforce. If not corrected, the differences between human factors subjects and those of the American workforce will increase at a magnified rate. To ensure that the results produced from human factors experiments are useful and valid, researchers should first analyze the diverse characteristics of their intended users and select subjects who possess these characteristics.
