2. ELEC4011 - Lecture5: Eng'g as social experimentation 2 Introduction Objective: Relate ethical theories to engineering practice A useful perspective: View engineering activities as social experiments: Engineers create experimental situations through innovation Society participates in these experiments as subjects Uncertainty about outcomes implies risk: Important to identify & quantify risks where possible Decision makers may make biased decisions unless accountable for (uncertain) outcomes

3. ELEC4011 - Lecture5: Eng'g as social experimentation 3 Roles of experimenter & subject Ethical issues for engineers as experimenters: Duties to experimental subjects Rights of experimental subjects Assessment of costs & benefits of the experiment Relationship between experimenter & subject: Legal framework: Legal obligations on experimenter, but these may not address innovative situations Codes of ethics: Primary responsibility lies with the experimenter

4. ELEC4011 - Lecture5: Eng'g as social experimentation 4 The Engineering Process

5. ELEC4011 - Lecture5: Eng'g as social experimentation 5 Examples Computers: Developed & adopted over about three decades Significant impacts on society: Not well understood or nor always predicted, e.g: The Y2K bug However largely accepted as a positive technology Nuclear power stations Developed & adopted over about three decades Significant impacts on society: Not well understood nor always predicted, eg. Chernobyl Widespread concern & installed capacity in decline

6. ELEC4011 - Lecture5: Eng'g as social experimentation 6 Experimental attributes of engineering Incomplete understanding of implications: Insufficient time or money Commercial advantage (desire for secrecy) Uncertainty about impacts (sometimes unknowable) Participation of experimental subjects: Products or services often target non-engineers Subjects share responsibility if voluntarily accept risk Reasons for monitoring outcomes: Commercial purposes (e.g. product improvement) Precautionary purposes (e.g. manage risk)

7. ELEC4011 - Lecture5: Eng'g as social experimentation 7 Nature of subjects & impacts Subjects: Individual consumers, groups or society as a whole: Those who can make informed choices, and Those requiring advocates: Disadvantaged, future generations, other species & the environment Impacts: Health, safety & the environment Changes to social structure & social status: Income & wealth distribution Lifestyles & personal empowerment Education, culture

8. ELEC4011 - Lecture5: Eng'g as social experimentation 8 Features of engineering experiments Absence of a �control group� ( equivalent non-participants): Products & services usually offered to all Benefits may such that they can�t be withheld from a particular group Society may have little prior understanding: Innovative products & services Uncertainty in future impacts (positive or negative) Informed judgements are difficult to make: For both experimenter and subject

9. ELEC4011 - Lecture5: Eng'g as social experimentation 9 Informed consent Stakeholders: Experimental subjects, experimenters, others who can affect the outcome, or may be affected by it Stakeholders have a right to informed consent: A voluntary & conscious decision made on the basis of all relevant information Issues: Identification of stakeholders (present & future) Adequacy of information Decision making opportunity & capability

10. ELEC4011 - Lecture5: Eng'g as social experimentation 10 Issues for �informed consent� Voluntary participation not always possible, eg: Technology that has widespread effects on the public: For example, the Y2K bug Future generations or citizens of other countries Stakeholders may be hard to identify, eg: Those affected by the Chernobyl nuclear accident Proxy group can represent unknown stakeholders: Adequate diversity & information Adequate decision making competence Strongly differing opinions may hamper consensus

11. ELEC4011 - Lecture5: Eng'g as social experimentation 11 Current examples Consideration of an Australian Republic: Constitutional convention, referendum Introduction of genetically modified (GM) foods: Companies have not always revealed GM ingredients Legal requirements under development Electromagnetic radiation from cellular phones: Some companies provide information, headphones Telephone caller ID: Defaults �on� but �off� would allow informed consent

12. ELEC4011 - Lecture5: Eng'g as social experimentation 12 Summary Engineering is a form of social experimentation: Innovation with social & environmental impacts Uncertainty & risk in outcomes Stakeholders have a right to informed consent: Information, opportunity, decision making capability Problems in implementation: Lack of a control group & corporate pressures Difficulty in identifying stakeholders Irreducible uncertainty
