6. Principles of Technology Ethics
Proportionality - The good achieved by the technology must 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
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
