Decisions are everywhere. They are present in every aspect of our lives (such as healthcare and finances) and they are taken at multiple levels (personal,  social, and policy). Many of the decisions we face have an explicit or implicit ethical dimension and thus require normative judgements. The CRE is uniquely positioned to address the normative dimensions of decision making through the expertise of its various branches (axes). This overarching theme (theme phare) explorers the ethics of / the normative dimensions of decision-making related to health, economy, politics and the environment. Building on existing research projects and research interests of its researchers and trainees (postdocs and grad students), this theme engages the entire CRE community in a stimulating and productive exchange of ideas regarding how to enhance decision making, ensuring it is informed not only by the appropriate evidence-base, but also by clear ethical conceptual analysis.
