Abstract
To promote ethical conduct in science, government funding agencies, academic institutions, and professional journals have defined some types of seriously unethical behaviors as research misconduct and have developed policies and procedures for reporting, investigating, and adjudicating allegations of misconduct. Behaviors that are not as egregious as misconduct but are still regarded as unethical are called questionable research practices. Although there is considerable variation in research misconduct definitions used by different organizations and nations, most of them classify data fabrication or falsification or plagiarism as misconduct. This chapter will distinguish between research misconduct, questionable research practices, and fraud; describe policies and procedures related to misconduct; review some famous cases of misconduct; examine the prevalence and causes of misconduct; and discuss ways of preventing misconduct.
