But research is a good thing… why do research subjects
need “protection?”

Concerns for protecting subjects grew out of a long
history in which people were abused in the name of science

NUREMBERG CODE1947
NUREMBERG CODE1947
• Voluntary informed consent absolutely essential• Research should yield useful results• Base research on prior work• Avoid physical and mental suffering• No expectation of death or disabling injury• Risk must be outweighed by importance• Subjects must be protected from injury• Qualified scientists, adequate facilities• Subject free to stop at any time• Investigator must be ready to withdraw subject
![Page 8: Daniel Nelson Director, Office of Human Research Ethics Professor of Social Medicine, Adjunct Professor of Pediatrics University of North Carolina - Chapel.](https://reader037.fdocuments.net/reader037/viewer/2022110205/56649c935503460f9494e4ad/html5/thumbnails/8.jpg)
“Before IRBs, the only consent required was that of a researcher's department head. The Nuremberg Code was ignored in practice. As I look back on it, the interpretation of these codes was that they were necessary for barbarians, but not for fine upstanding people... In this prestigious unit we had a very strong obligation to behave in a civilized manner.”
Dr. William Silverman, Columbia pediatrician, on the postwar mentality (ACHRE interviews)

“Sometimes, with the best of intentions, scientists and public officials… working for the benefit of us all, forget that people are people. They concentrate so totally on plans and programs, experiments, statistics- on abstractions- that people become objects, symbols on paper, figures in a mathematical formula…”
