next to the traffic signal because that is where they are looking

53
Q

determining what behaviors to value are not likely within the realm of science

77
Q

why is ethics so important in research and clinical practice?

A

because people are capable of horrible acts without some method to insure ethical practice

78
Q

four threats to ethical behavior

A
  1. unitarianism applied to people- treating people as objects or things; viewing people’s worth as what they contribute
  2. scientism- places science as the highest value; at a higher extreme, it puts answering scientific questions above other considerations
  3. rationalization- biased justification of our behavior; we are prone to doing this
  4. the greater good- concerned with making a perfect world; explains that the ends (results) justify the means to do so
