This work is motivated by a question at the heart of unsupervised learning approaches: Assume we are collecting a number K of (subjective) opinions about some event E from K different agents. Can we infer E from them? Prima facie this seems impossible, since the agents may be lying. We model this task by letting the events be distributed according to some distribution p and the task is to estim...

A cornerstone of the task switching literature is the finding that task performance is typically slower and more error-prone when the task switches than when it repeats. So far, deception research has largely ignored that such cognitive switch costs should also emerge when switching between truth telling and lying, and may affect the cognitive cost of lying as reflected in higher prefrontal bra...

This article discusses the ethical necessity of health care workers telling their patients the truth about both their diagnosis and prognosis. This necessity is based upon respect for persons, utility, and kindness. Within this ethical obligation to tell the truth, however, there are several different ways in which the truth can be told. In particular, this paper stresses that telling patients ...

Are doctors and nurses bound by just the same constraints as everyone else in regard to honesty? What, anyway, does honesty require? Telling no lies? Avoiding intentional deception by whatever means? From a utilitarian standpoint lying would seem to be on the same footing as other forms of intentional deception: yielding the same consequences. But utilitarianism fails to explain the wrongness o...

One of the most difficult ethical dilemmas facing health care professionals working in oncology is whether, when, how and how much to tell terminal cancer patients about their diagnosis and prognosis. The aim of this article is to review the trends in this issue worldwide. While a majority of physicians in both developed and developing countries tell the truth more often today than in the past,...

Problem Truth-telling is an important component of respect for patients' self-determination, but in the context of breaking bad news, it is also a distressing and difficult task. Intervention We investigated the long-term influence of a simulated patient-based teaching intervention, integrating learning objectives in communication skills and ethics into students' attitudes and concerns regardin...
