Ethics in psychology refers to the moral principles that guide the conduct of psychologists in their research and practice. These guidelines ensure the welfare, dignity, and rights of individuals involved in psychological studies or therapy. Key ethical principles include informed consent, confidentiality, and the avoidance of harm, which help maintain trust between psychologists and their clients or research participants. Professional organizations, such as the American Psychological Association (APA), provide ethical codes that outline acceptable practices. These codes help psychologists navigate complex situations, ensuring that their work contributes positively to society while respecting the rights and well-being of individuals.
