ABSTRACT The authors argue that individual psychologists have an obligation to understand, review, and comment on upcoming revisions of the Ethical Principles of Psychologists and Code of Conduct. Psychologists may want to consider several factors as they review and prepare comments on these revisions. Among other things, commenting psychologists should consider the purposes of ethics codes and how the writing of a code can meet or balance these often-conflicting purposes; the overarching ethical theory or theories that should form the basis (...) of the APA Ethics Code; and the extent to which individual standards are useful and comprehensive, and avoid unnecessary harm to both the public and psychologists. The authors provide examples from the current and recent APA Ethics Codes to illustrate the types of decisions that psychologists must make when evaluating revisions to the APA Ethics Code. (shrink)
