This paper proposes to engage in the investigation of psychological experiments on humans throughout history and whether or not the ends justify the means. I will use many experiments in my essay that were performed at various times, as well as experiments where the subjects did not consent to participate in. By using many different experiments in different time periods, it will help to develop how psychologists in the past got away with so many verses how in today’s society it isn’t as easy to do. This essay will serve as an in-depth analysis of specific experiments, how it affected the participants, and if psychological advances were made due to them. If the experiments mean to justify the means, is it still ethical to put participants through psychological torment?
