APA Ethical Principles of Psychologists and Code of Conduct or Ethics Code
The five general principles are beneficence and nonmaleficence, fidelity and responsibility, integrity, justice, and respect for people's rights and dignity.
Evaluating psychological research can be as sensitive as conducting psychological research. Results, if handled unethically, might compromise subject's good name, their roles and community standing, their sense of self-worth, their sense of inviolate privacy among other dangers from mishandled evaluative psychological data.
Two prominent ethical dilemmas that can and do arise are the ideas of "harm" and "deceit." A researcher may in means and at no stage deceive subjects about research or evaluation of research results. A researcher must do no harm to subjects. In the case of psychological research evaluation, that means do no psychological harm (American Psychological Association).
