Diane Vaughan’s analysis of the causes of the Challenger accident suggests ways to apply science and technology studies to the teaching of engineering ethics. By sensitizing future engineers to the ongoing construction of risk during mundane engineering practice, we can better prepare them to address issues of public health, safety, and welfare before they require heroic intervention. Understanding the importance of precedents, incremental change, and fallible engineering judgment in engineering design may help them anticipate potential threats to public safety arising (...) from routine aspects of workplace culture. We suggest modifications of both detailed case studies on engineering disasters and hypothetical, ethical dilemmas employed in engineering ethics classes. Investigating the sociotechnical aspects of engineering practice can improve the initial recognition of ethical problems in real-world settings and provide an understanding of the role of workplace organization and culture in facilitating or impeding remedial action.

The Ford Pinto’s fuel tank was prone to rupture in collisions above 20 mph, sometimes resulting in burn deaths. An infamous Ford memo estimated the cost of a shield correcting the problem at $11. Should Ford have installed the shield, holding public safety paramount, or, respecting consumer autonomy, have made the shield an option? Answering this question requires distinguishing between three kinds of autonomy: merechoice autonomy (deciding something for oneself, regardless of the content of the choice), proclamative autonomy (making a (...) choice that holds up a value or standard, commitment to which is partly definitive of who one is), and high-impact autonomy (making a choice that profoundly affects one’s ability to make proclamative choices). (This is not a formal distinction, that is, a distinction meant be to be clear, rigorous, and neutral). Autonomy is thus asymmetric: choosing to do x may be highly proclamative while choosing not to do x is not. In the Pinto case, not giving consumers the option of declining the shield undercuts only mere-choice autonomy. Several arguments are provided (including an argument based on the nature of moral agency) that proclamative autonomy (and, derivatively, high-impact autonomy), rather than mere-choice autonomy, has significant positive value. More precisely, it is argued that, as a rule, the more proclamative a choice is, other things being equal, the more weight autonomy claims about that choice possess. The paper concludes that common sense is correct about the Pinto case. In some instances, consumer choice may legitimately count more than the engineer’s commitment to public safety (particularly when proclamative choice is involved). However, losing the opportunity to save $11 is not too large a price to pay in order to counter market pressures against safety by inducing in engineers a professional commitment to put safety first.
