 today we are going to look at some more traditional case studies like we are talking about the wilbrook experiment wilbrook experiment is very important and is classically known because it mentally retarded children and those mentally retarded children were intentionally given the hepatitis germs like in those mentally retarded children the life germs of hepatitis were induced to see the progression of that disease and parents had an obligation for them that their mentally retarded children can only be admitted in that organization when they sign this informed consent that they will make a part of this experiment for their children when they were not told that what will be the nature of this experiment so this is very unethical and due to this they had to face a lot of viral infection so exploitation of a vulnerable group of subjects was a big question in this research and with holding information from the parents about this particular disease in your child we are intruding and investing in that disease and that progression will be studied scientists have justified it that if those children are mentally retarded then their health can be put at risk and their research can be used to keep normal children healthy but in nowadays we can't do any such kind of experiment another one is the famous one Milgram experiment Milgram's studies which are very famous for studying obedience to authority some participants were given the autonomy that they will give them an electric shock through a liver the experiment was named as how many obedience you have to follow the authority the authority tells you to push the liver the more you push, the more electric shocks the subjects will get in that experiment, the noise and pain of the subjects were heard but by following the obedience to authority they were giving more electric shocks although the experiment was a little deceptive, the electric shock was not that intense but they were portraying that they are feeling a lot of shocks and pain but a human behaviour study was done that a human subject can inflict a maximum pain to the individual but the very nature of the experiment was unethical and the major ethical problem involved into it is that most of the participants experienced very high level of stress and because of that some of them refused to be part of the experiment then Jewish chronic disease this is another important classical case study in which the liver cancels cells but injected into a saline patients the patients of very old age population the researchers believed that the cells will be rejected but still they tried to attempt that with old age population and without informed consent they did this procedure and used a vulnerable group of individuals so that experiment is also a classical case study which is still questionable the Zimbardo prison study is also very important and in this situation when Zimbardo planned a study that he wants to see a specific role playing effect he wants to see a simulation he wants to see a labelling and he wants to do a social experiment he was a participant he put them into an unpleasant situation like he said that you need to behave like the prisoners and at night he used to sleep in his bed take a seat he used to be very abusive with them he was in a situation where the simulation was a prison like he was locked up there which has definitely hampered their self respect their basic human rights and his ethical setup was not that he was treated this way although they were the students of psychology and he was experimented with them after that he was debriefed that this was just an experiment and he wanted to see that in a social setting how an individual feels but still this experiment is very much questionable because he created a lot of distress in the participants so such type of unethical studies are no longer being used into practice these days any research which creates an emotional discomfort which gives participants any type of psychological or physical harm such type of research is to date now we don't practice in fact we refer to these old experiments that what could be the possible implications of all these things which are being done into a social setting
