I believe that the Milgram Experiment was in fact ethical. I only say this because the learner Mr. Wallace was only administered a single 45 volt shock each time. Had the subject that was being shocked been someone they chose off the street like the teacher thought they were and had they actually given them up to a 450 volt shock I would say the experiment would have become certainly unethical. The research that was done did not actually cause any bodily harm to Mr. Wallace or the test subject so I do not find it to be unethical.
When faced with the question whether the Zimbardo Experiment was ethical or not I am forced to say no this was not ethical. I say this because unlike the Milgram Experiments the people in the role of prisoner were actually harmed. The prisoners were harassed and stripped down and given numbers as names which could probably cause mental harm. The things that these volunteers were put through just to do an experiment to see how people adapt to authoritative roles was in my opinion an acceptable and quite unethical.
In my opinion the Milgram experiment was worth the risk and worth the results. I say this because to my knowledge none of the participants were harmed in conducting this experiment. On the other hand, the Zimbardo Experiment in my opinion went way overboard with what they were trying to accomplish. Actually allowing people to be treated this way was unethical in my opinion because of the fact the subjects may have easily been harmed in a multitude of ways both mentally or physically.
If i were a professional sociologist i would be interested in studying the ways in which drugs and alcohol impact different societies. With their use being so widespread throughout many cultures for thousands of years I think that it would be interesting to conduct and experiment in which these effects could be monitored. I think it could help shed some light on the subject both good or bad.
