Answer 2

It depends on whose ethics you are using. The value of the knowledge gained from the study needs to be balanced with the potential harm to the subjects. Animal lovers might disagree with Ms.Sue's response, seeing many studies as animal cruelty.

Also, I doubt if you could get any results from animals that could simulate the responses of humans in Zimbardo's Stanford Prison Study.
