Looking for examples of unethical research

FEEDBACK PLEASE: I'm working on a new corporate User Research training program and looking for examples to underscore the significant ethical considerations we navigate in UX Research.

The set up begins with some foundations then dives into the examples.

• User research is the process of figuring out how people interpret and use products and services.

• We’re looking for "people problems”

• People problems are needs and issues articulated by people on the street

• We’re looking for underlying motivations and behaviors

• User research helps us build empathy for the user in an evidenced based, structured manner

• User research is one of several inputs into making the best possible and most important decisions

• The reason UXR exists as a function, and a field, is that it's VERY easy to do poorly

• There are also significant ethical considerations

What other examples would be helpful to add? Please add your comments below! TIA
