Sarah Franklin’s message that “we must all be ethicists now” is laudable if it sensitizes researchers to the importance of ethical thinking (Nature 574, 627–630; 2019). We are concerned, however, that it could be misinterpreted to mean that expertise in ethics is no longer necessary for discussing issues pertaining to science and technology. This implication is dangerous in a society in which there is a mounting distrust of institutions and expert knowledge.
