We exploit the fact that generosity and trustworthiness are highly correlated and the former can thus be a sign of the latter. Subjects decide between a generous and a mean split in a dictator game. Some of them are informed from the start that afterwards they will participate in a trust game and that their choice in the dictator game may matter; others are not informed in advance. In the trust game, before trusters decide whether or not to trust, some trustees can reveal (or conceal) only their true choice in the dictator game, while others can say to trusters, truthfully or otherwise, what they chose. We find that a generous choice made naturally by uninformed trustees and reliably revealed is more effective in persuading trusters to trust than a generous choice that could be strategic or a lie. Moreover, we find that, when they can, mean subjects lie and go on to be untrustworthy.

Conventions are arbitrary rules of behavior that coordinate social interactions. Here we study the effects of individuals' social value orientations (SVO) and situational conditions on the emergence of conventions in the three-person volunteer's dilemma (VOD). The VOD is a step-level collective good game in which only one actor's action is required to produce a benefit for the group. It has been shown that if actors interact in the payoff-symmetric VOD repeatedly, a turn-taking convention emerges, resulting in an equal distribution of payoffs. If the VOD is asymmetric, with one "strong" actor having lower costs of volunteering, a solitary-volunteering convention emerges by which the strong actor volunteers earning less than others. In study 1 we test whether SVO promotes turn-taking and hampers solitary-volunteering. We find that groups with more prosocials engage less in turn-taking and no effect of SVO on the emergence of solitary-volunteering. In study 2 we test whether making one actor focal is sufficient for solitary-volunteering to emerge. We find instead that payoff asymmetry with one strong actor is a necessary precondition. We discuss explanations for our findings and propose directions for future research.

"A 'smart' bioethics is an ethics that is able to recognize and address the real-life and context-embedded moral concerns of the people it intends to serve, whether those people are patients, relatives, healthcare professionals, researchers or policy-makers. Therefore, close-listening to what those people have to say, should be at the start of each bioethics-undertaking. In this presentation, I will explore how narrative approaches taken from the humanities and social sciences could help bioethicists in the 21st century to attune to and examine both the stories of others and the stories we create ourselves in medicine and bioethics. I will discuss why this is an essential first step before we embark on the normative task of bioethics, and how it entails a scrutinization of epistemological and meta-ethical positions. Following, I will use my own research project –an empirical-ethical exploration of physician-assisted dying in Dutch general practice– as an example of how narrative approaches used in empirical research, training of researchers and normative evaluation may change one's perspective on a highly contested bioethical issue. Last, I will discuss the question whether concepts such as narrative humility and epistemic (in)justice could and should receive more attention in bioethics-training and-research. "
