Are there any research topics or groups of people you would consider always unethical to study?

Finding Inspiration for Your Research
Step 1:
Describe a recent event that led you to wonder more about some topic. For example, maybe the last time you went to a party, it made you think about what kinds of people tend to show up at them. Or you noticed that at the multiplex theaters, people from different racial/ethnic groups were not going to the same movie, so you thought it would be interesting to study who goes to which movies.
Are there any research topics or groups of people you would consider always unethical to study?
Using a theory you learned in another class, suggest what research topics could be derived from it.
Draft three research questions about the topic.
Step 2:
Write a response to at least 1 classmate. Responses may include the following:
Ask for clarification
Expand on or clarify an important point.
Offer an additional argument to support a position taken in an answer.
Suggest ways in which an idea could be more clearly expressed.
Identify passages where you think the writer misunderstood a concept or applied it incorrectly.
Disagree with a point or position made in an answer.
