outweigh the harm or risk; there must be no alternative that achieves the same or comparable benefits with less harm or risk
• Informed Consent• Those affected by the technology should
understand and accept the risks
13-15
Principles of Technology EthicsPrinciples of Technology Ethics
• Justice• The benefits and burdens of the technology
should be distributed fairly. • Those who benefit should bear their fair share
of the risks, and those who do not benefit should not suffer a significant increase in risk
• Minimized Risk • Even if judged acceptable by the other three
guidelines, the technology must be implemented so as to avoid all unnecessary risk
