Peer prediction mechanisms incentivize self-interested agents to truthfully report their signals even in the absence of verification by comparing agents’ reports with peers. We propose two new mechanisms, Source and Target Differential Prediction, prove very strong guarantees for a general setting. Our Prediction are strongly truthful : Truth-telling is strict Bayesian Nash equilibrium. Also, t...

Ms. S is a 42-year-old Russian woman who immigrated to the United States two years ago; she recently was diagnosed with stage III-A breast cancer. She underwent a partial mastectomy six weeks ago and was scheduled to begin adjuvant chemotherapy with doxorubicin and cyclophosphamide. Ms. S neither speaks nor understands English, and throughout her diagnosis and initial treatment, she appeared an...

Can deceitful intentions be discriminated from truthful ones? Previous work consistently demonstrated that deceiving others is accompanied by nervousness/stress and cognitive load. Both are related to increased sympathetic nervous system (SNS) activity. We hypothesized that SNS activity already rises during intentions to lie and, consequently, cues to deception can be detected before stating an...

The aim of this article is to examine the relationship between trust, testimony and truth recovery processes as part of post-conflict transition. The paper uses the case study of unionist attitudes toward a community-based truth-telling project in Northern Ireland to demonstrate the impact an absence of trust can have upon what the French philosopher Paul Ricoeur has described as the ‘space of ...

The attitudes of the Greeks, a Mediterranean population, to the issue of telling the truth to the patient have been studied. There is no clear answer to the question: 'Do the Greeks wish to be informed of the nature of their illness?'. The answer is: 'It depends'. It depends on age, education, family status, occupation, place of birth and residence and on whether or not they are religious peopl...

The standard of professional candour with patients has undergone a significant change over the past 30 years. Independent of their obligation to disclose information necessary for informed consent, physicians are increasingly expected to communicate important information to patients that is not immediately related to treatment decisions. The purpose of truth telling is not simply to enable pati...

Criteria for evaluating school choice mechanisms are first, whether truth-telling is sometimes punished and second, how efficient the match is. With common knowledge preferences, Deferred Acceptance (DA) dominates the Boston mechanism by the first criterion and is ambiguously ranked by the second. Our laboratory experiments confirm this. A new ex ante perspective, where preferences are private ...

We introduce a novel decision problem to experimentally study situations where people know that they can lie, but do not initially know the economic consequences: they have to invest time to find them out. We report numerous findings, the most intriguing of which is that, in our setting, people can be divided in three types: the Good, who act honestly independently of the corresponding payoff; ...

OBJECTIVE The aim of this study was to explore the experiences and preferences of terminally ill cancer patients regarding truth telling in the communication of poor prognoses. METHOD We recorded and transcribed interviews with 45 patients who knew their cancer was terminal, and analyzed their responses hermeneutically. RESULTS Patients identified three different modes of truth: (1) the abs...
