Abstract
We have recently reached a watershed in the research community’s consideration of the ethics of research. The way is now open for a more nuanced discussion than the one of the last decade in which attention to legal and quasi-legal procedures for handling misconduct dominated. The new discussion of ethical issues focused on trustworthiness takes us beyond consideration of conduct that is straightforwardly permitted, forbidden or required, to consideration of criteria for responsible behavior. This paper develops an overview of the subject of trustworthiness among researchers. It illustrates and discusses various types of betrayal and defections in research conduct, and locates these in relation to many of the situations discussed elsewhere in this issue.
