Questionable research practices violate the American Psychological Association's Code of Ethics.

In this viewpoint article, the authors assert that psychology is in the midst of a "replication crisis" due to factors such as low power, p-hacking, publication bias, and hypothesizing after the results are known (HARKing). Individually, these practices have been decried for decades, but only in the last 15 years has the corrosive effect of these practices been fully appreciated. The authors contend that these practices are more than "questionable" and constitute unethical research practices according to the American Psychological Association's (2017) Ethical Principles of Psychologists and Code of Conduct. The public deserves the ethical and honest practice of clinical science described by APA's ethics codes. Although these issues cut across all subdisciplines of psychology, they take on special importance within clinical psychology where research on assessment, diagnosis, and treatment of mental health problems have meaningful real-world implications.
