ABSTRACT
I return in this chapter to scientifi c research performed on human subjects, in particular clinical research in biomedicine and related fi elds. My initial focus will be on the importance of fairness. I then turn to the issues of lying and deception. After providing a number of accounts of the wrongfulness of lying, all of which permit some lies, I argue that the real ground for the moral wrongness of lying is to be found in the value of personal integrity. This value grounds an absolute prohibition on lying. Such an absolute prohibition has signifi cant consequences for the ethics of inquiry, in clinical research, but also in social science research, and police, military, and journalistic investigations.
