It has been illegal to treat humans like guinea pigs since the Nuremberg trials, in which Nazi doctors were punished for doing unspeakable things to prisoners. These days, we have to explain the experiment to the people taking part in trials for new treatments and get their permission (their “informed consent”).
A fascinating discussion and useful suggestions.
It is also an ethical requirement to avoid unnecessarily harming patients. A recent study published in the BMJ Journal for Medical Ethics shows that the relatively recent discovery of so-called nocebo effects – a result of the patient’s expectation that the treatment will harm them – means that harm is being done by the way we inform patients about the trial in which they are taking part.
