Social, Ethical, & Political Social, Ethical, & Political ConsiderationsConsiderations
Learning OutcomeLearning Outcome
To develop an appreciation for how various non-technical – social, ethical and political – considerations are not only
embedded in the design process but also how they
positively constrain and shape the design process,
technological artifacts, and human behavior.
Engineering DesignEngineering Design
The process of developing technological artifacts, processes or systems to meet
recognized social need Includes everything from the initial
conceptualization of a design to the final production and implementation
Many factors influence and constrain the design process: both technical and
non-technical
Technological vs. Technological vs. Product DesignProduct DesignTechnological Design
Product Design
Development of “unique technically oriented solutions to specific
problems”
Development of artifacts, processes, or systems that not only perform
specific functions but that also can be economically mass produced
Is there always or even Is there always or even ever one best design ever one best design
solution?solution?
““Engineering design is Engineering design is surprisingly open-ended. A goal surprisingly open-ended. A goal may be reached by many, many may be reached by many, many different paths, some of which are different paths, some of which are better than others but none of better than others but none of which is in all respects the best which is in all respects the best way.”way.”E. Ferguson, Engineering and the Mind’s Eye. MIT Press, 1992: 23
Applied Science MythApplied Science Myth
• Engineering is merely the application of scientific knowledge to social
problems
• Wish to portray engineers as agents of progress; however, since science was
assumed to be the cause of progress it was necessary to claim engineering was
applied science
• Technology consists of applying the fruits of the basic sciences in a more or
less mechanical manner• Engineering a giant machine receiving its intellectual fruit from the supposedly
more fundamental sciences
Technological Technological DeterminismDeterminism
• Technological artifacts, systems, & processes develop as a result of some
internal dynamic, unmediated by personal concerns, social forces, or other
factors• Social arrangements necessary for implementation of technologies are often presented as objective social necessities
• Technologies and related social structures are thus viewed as determined
OptimizationOptimization• Essential to engineering design
• Seeks to adapts engineering artifacts to particular goals and values through trade-offs, i.e., maximizing certain
benefits and minimizing undesirable outcomes• Optimization is different than efficiency
which is the maximization of outputs with respect to inputs
• Optimal Designs are not always the most efficient
As we look behind the scenes, we As we look behind the scenes, we find major influences on decision-find major influences on decision-making coming from the making coming from the individual’s own value system, individual’s own value system, from that of his organization, and from that of his organization, and from the culture, as well as from from the culture, as well as from the technology. the technology.

Engineering designs, i.e., Engineering designs, i.e., the technological artifacts, the technological artifacts,
processes, and systems processes, and systems generated by engineers, generated by engineers, explicitly incorporate, explicitly incorporate,

• Gender stereotypes do infiltrate the software design process
• Educational software designed for boys looked like games while those designed for girls looked like tools
for learning
• Performances varied if a subject used the software designed for the other gender BUT this effect only
occurred when the software was used in public (socially constructed expectations of success come into
play)• Programmer provides one context while the social setting provides another – together these determine
the users sense of success
Given all these values in the Given all these values in the design process, should design process, should
technical considerations be technical considerations be subordinated to the subordinated to the
subjective decisions?subjective decisions?
Social DeterminismSocial Determinism
• Technological artifacts, systems, and processes themselves are not what it
important
• Social structures they are embedded in and circumstances out of which they
develop are what is important
• This is better but still WRONG: It ignores the process of optimization and the inherent trade-offs between various
goals
Technological PoliticsTechnological Politics
• Technology and technological artifacts are politically important in their own
right• This analysis pays attention to large-scale socio-technological systems and
the responses of society to certain technological imperatives
• Human goals and purposes are transformed as they are adapted to
specific technological means• Focus is on the characteristics of
technological artifacts and their meanings
2 Senses of 2 Senses of Technological PoliticsTechnological Politics
• First: “instances in which the invention, design, or arrangement of a
specific technical device or system becomes a way of settling an issue in the
affairs of a particular community”
• Second: When technologies “appear to require, or to be strongly compatible
with, particular kinds of political relationships”

IEEE Code of EthicsIEEE Code of Ethics
1. to accept responsibility in making engineering decisions consistent with the safety, health and welfare of the public, and to disclose promptly factors that might endanger the public or the environment;
2. to avoid real or perceived conflicts of interest whenever possible, and to disclose them to affected parties when they do exist;
3. to be honest and realistic in stating claims or estimates based on available data;
4. to reject bribery in all its forms; 5. to improve the understanding of technology, its appropriate application,
and potential consequences; 6. to maintain and improve our technical competence and to undertake
technological tasks for others only if qualified by training or experience, or after full disclosure of pertinent limitations;
7. to seek, accept, and offer honest criticism of technical work, to acknowledge and correct errors, and to credit properly the contributions of others;
8. to treat fairly all persons regardless of such factors as race, religion, gender, disability, age, or national origin;
9. to avoid injuring others, their property, reputation, or employment by false or malicious action;
10.to assist colleagues and co-workers in their professional development and to support them in following this code of ethics
We, the members of the IEEE, in recognition of the importance of our technologies in affecting the quality of life throughout the world, and in accepting a personal obligation to our profession, its members and the communities we serve, do hereby commit ourselves to the highest ethical and professional conduct and agree:
