Answer:
Deception
Explanation:
American Psychological Association (APA) published its first Ethical Principles of Psychologists and Code of Conduct in 1953. It presented a layout for psychologists to act morally, ethically and intellectually related to decisions in research, practice and education.
Deception has been categorized as unethical if it has ill intention or malicious and can prove catastrophic for the subject. However, it is performed to dive deep into human psychology. The psychologists are advised not to use deception until there is a case that truly needs it. They are then directed to mitigate its use and pacify as soon as possible due to its unethical nature.
