There is an emerging experimental trend in bioethics and neuroethics. We briefly review several topics in this trend and discuss how the existing and future studies can have normative implications related to bioethical/neuroethical issues. Particularly, we consider three major ways to draw such implications; (1) contributing to conceptual analysis and philosophical (counter-)evidence, (2) figuring out the unreliability of moral thinking and thereby providing a debunking argument, and (3) estimating the feasibility of ethical norms and policies.
