Moral Complexity in Traffic: Advancing the ADC Model for Automated Driving Systems.

The incorporation of ethical settings in Automated Driving Systems (ADSs) has been extensively discussed in recent years with the goal of enhancing potential stakeholders' trust in the new technology. However, a comprehensive ethical framework for ADS decision-making, capable of merging multiple ethical considerations and investigating their consistency is currently missing. This paper addresses this gap by providing a taxonomy of ADS decision-making based on the Agent-Deed-Consequences (ADC) model of moral judgment.

What's Left of Moral Bioenhancement? Reviewing a 15-Year Debate.

Should we implement biomedical interventions like psychopharmaceuticals or brain stimulation that aim to improve morality in society? Since 2008, moral bioenhancement (MBE) has received considerable attention in bioethics, generating wide scholarly disagreement. However, reviews on the subject are few and either outdated or not structured in method. This paper addresses this gap by providing a scoping review of the last 15 years of debate on MBE (from 2008 to 2022).
