It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

DeJoy, David M. (1989): Consumer Product Warnings: Review and Analysis of Effectiveness Research. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 936-940.

This paper provides a critical review of recent research (1984-1988) on the effectiveness of consumer product warnings. The majority of available data come from laboratory studies of college students, and wide variations in effectiveness have been reported. The perceived hazardousness of the product, its familiarity, and the ease of complying with the warning all appear to be important factors. Some preliminary trends have emerged concerning the contribution of various message attributes; however, these factors do not appear to be as important as the user's product-related expectations. The implications and limitations of these findings are discussed.

DeJoy, David M. (1988): Human Factors Model of Workplace Accident Causation. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 958-962.

This paper proposes a human factors model of workplace accident causation. Particular attention is given to merging traditional human factors considerations with those related to self-protective behavior. The model focuses on human error, and three categories of diagnostic factors are proposed for analyzing the determinants of error. The diagnostic factors include: person-machine communication, environment, and decision-making. These factors are then linked to three general types of interventions: those involving system modification, organizational modification, and self-protection.

DeJoy, David M. (1987): The Optimism Bias and Traffic Safety. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 756-759.

In this study, college students were asked to rate their overall accident likelihood, driving skill, and level of safety relative to other drivers. They also made comparative risk judgements for a variety of specific accident situations. Consistent with previous research, subjects perceived themselves as safer, more skillful, and less likely to be involved in an accident than other drivers. Optimism increased with driving experience, but was unrelated to age or sex. Substantial optimism was also evident in response to the specific accident situations, and further analysis indicated that the perceived controllability of the accident was a strong predictor of optimism. The importance of controllability in this study is consistent with research on other life events, and suggests that perceptions of control play an important role in the optimism bias.
