Engineering empathy

Engineering ethics is preoccupied with technical failure. To ameliorate the risk that engineering works might either blow up or fall down, the engineering code of ethics provides guidance of how engineers should conduct themselves. For example, the Fundamental Canons in the National Society of Professional Engineers code of ethics states that engineers should hold paramount the health, safety and welfare of the public. As a result, engineering designs meet basic human needs such as food, water and shelter -- at risks that are generally considered acceptable. However, even safe designs fail to meet our needs ranked higher in Maslow's hierarchy -- such as belonging, esteem and self-actualization. While these have historically not been ethical priorities, increasing expectations in developed countries now include more complex ethical concepts such as sustainability and social justice. We can expect these trends toward higher and more complex human needs to continue -- although the profession seems ill-prepared. We argue that an empathic approach to engineering design is necessary to meet these higher needs of developed and developing societies. To guide engineers towards this approach, we propose a pluralistic interpretation of empathy grounded in an understanding of the three parts of the mind: cognitive, affective, and conative. In fact, product designers already use empathy in their design processes. However, an exemplar of an empathic design is harder to find in civil engineering disciplines. This paper discusses an example of the Hoover Dam Bypass, which resulted in an award-winning design and construction that improved traffic flow, reduced vulnerability to terrorist attack, and accounted for historical factors and environmental impacts. However, this technical success is an empathic failure. Although project leaders commissioned ethnographic studies to understand the impact the bridge would have on the local Native American populations and their cultural sites, the eventual design showed little consideration of the concerns that were revealed. For engineering designs such as bridges, other infrastructure and systems to meet the needs of the various populations in which they serve, engineers need to incorporate empathy into their designs.
