A pill to enhance moral behaviour, a treatment for racist thoughts, a therapy to increase your empathy for people in other countries – these may sound like the stuff of science fiction but with medicine getting closer to altering our moral state, society should be preparing for the consequences, according to a book that reviews scientific developments in the field.
Drugs such as Prozac that alter a patient’s mental state already have an impact on moral behaviour, but scientists predict that future medical advances may allow much more sophisticated manipulations.
The field is in its infancy, but “it’s very far from being science fiction”, said Dr Guy Kahane, deputy director of the Oxford Centre for Neuroethics and a Wellcome Trust biomedical ethics award winner.
“Science has ignored the question of moral improvement so far, but it is now becoming a big debate,” he said. “There is already a growing body of research you can describe in these terms. Studies show that certain drugs affect the ways people respond to moral dilemmas by increasing their sense of empathy, group affiliation and by reducing aggression.”
