Moral enhancement (abbreviated ME), also called moral bioenhancement (abbreviated MBE), is the use of biomedical technology to morally improve individuals. MBE is a growing topic in neuroethics, a field developing the ethics of neuroscience as well as the neuroscience of ethics. After Thomas Douglas introduced the concept in 2008, its merits have been widely debated in academic bioethics literature. Since then, and Julian Savulescu have been the most vocal MBE supporters. Much of the debate over MBE has focused on their 2012 book in support of it, Unfit for the Future? The Need for Moral Enhancement.
