1. Racial predisposition; this research violates very basic ethical code of racial discrimination. There is no way that a researcher can be allowed to target a specific group of people based on their biological race. This type of discrimination hinders the authenticity of research and have far reaching repercussions for the target group as well as the whole society.

Besides the electroshock are used on chronic psychic patients not on general public not even adults let alone the preteens.
3. Health Problems, Diet, and Socioeconomic Status; this research proposal is better than the previous two proposals but it has some ethical regarding the consequences of the publicly published findings. Rather it would be more effective to keep these findings to the policy makers and work for the betterment of the lower status peoples so that they can also eat healthy diet.
