He could’ve given the rabbits a variety of food with better nutrients but he wanted to show the difference in health between the rabbits because he wanted to show that all people whether healthy or not were at risk of having tuberculosis. Dr. Trudeau wanted to find a way to help people with the disease live longer and not live in misery. Measuring the dead rabbits wouldn’t help the experiment because the point of this experiment was to see if the environment a rabbit was in progressed the disease or slowed it down. Making measuring the survival time very important in this experiment. I would’ve changed the health of the rabbits to show the difference the disease impacted healthy and non-healthy rabbits. Groups 1-3 would have been the same as Dr. Trudeau but replaced with strong healthy rabbits. I would also have 3 more groups with unhealthy rabbit in the same environments as the first 3 groups.

HIV is virus that affects the immune system making a person more vulnerable to infections or disease. HIV has also been linked to AIDs an auto immune disease that also affects a person’s immune system.

The rush of immigrants may have brought the increase of TB because some may have been affected with HIV or TB before coming to the United States. Starting the Domino Effect around the U.S. causing the massive increase of TB cases there. Places such as prisons and homeless shelters are more susceptible of catching diseases such as TB because of the unsanitary conditions and the congestion of people in those facilities.

Among multiple issues including giving misleading information, the most dominate is the lack of consent Milgram received from his subjects to participate in such a test (102). While I do see that this is immoral, there is no way that Milgram could have completed his experiments effectively if he had done it morally. The first issue is if he explains what is actually going to happen during the experiments, that would obviously hurt the integrity of his results. Also, going back to how the experiments help us, if those who participated knew what was going to happen, it wouldn’t have affected them as severely.
