The APA’s Ethical Principles includes five basic principles (“Ethical Principles”).

Principle B, Fidelity and Responsibility, describes the importance of colleagues working together and establishing relationships with each other. This principle emphasizes the importance of being aware of conflicts of interest. Although Zimbardo may have been unbiased in the beginning, he ended up losing sight of the situation and overlooking abusive behavior (“Zimbardo”). Considering the experiment went on for much longer than it should have, Zimbardo’s colleagues clearly did not work together well. Principle C, Integrity, seeks to have psychologists strive to “keep their promise and to avoid unwise or unclear commitments”. Although prisoners and prison guards were aware that they were taking part in a mock prison experiment, they did not truly understand what they were getting themselves into.
