 As has been pointed out by several authors (Nissenbaum 1996; Johnson &amp; Powers 2005; Swierstra &amp; Jelsma 2006), it may be hard to pinpoint individual responsibility in engineering. The reason is that the conditions for the proper attribution of individual responsibility that have been discussed in the philosophical literature (like freedom to act, knowledge, and causality) are often not met by individual engineers. For example, engineers may feel compelled to act in a certain way due to hierarchical or market constraints, and negative consequences may be very hard or impossible to predict beforehand. The causality condition is often difficult to meet as well due to the long chain from research and development of a technology till its use and the many people involved in this chain. Davis (2012) nevertheless maintains that despite such difficulties individual engineers can and do take responsibility.
