10 Appalling Experiments Conducted on Humans
Unethical Human Experimentation
The atrocities carried out by some of these doctors, scientists and political groups are horrifying, but sadly, human experiments are a very real part of our history.
These are just a handful of the most famous instances of exploitation—some that have paved the way for change.

Who were the subjects?
At one point, inmates, the disabled, the physically and mentally sick, and the poor were all groups once considered fair game to use as subjects in research experiments.

Did they need permission?
No permission was necessary. Most researchers didn’t bother getting permission, and many doctors performed experiments on unwilling or unknowing subjects.

When did the rules change?
During the 1970s, the U.S. Congress changed the rules. Informed consent is now required for any government-funded medical studies that involve human subjects.

Exploitation
For many, many years, outrageous experiments were performed on humans with very little ethics involved. The exploitation and mistreatment were alarmingly high.
Here are 10 of the most appalling human-tested experiments.
