Professional ethicists appear to behave no differently than do non-ethicists of similar social background. However, ethicists also appear to embrace more stringent moral norms than do non-ethicists, at least on some issues. Part 1 will summarize the empirical evidence. Part 2 will discuss one possibly attractive response: that an ethicist's role is to espouse and defend moral norms, with no special obligation to live according to the norms she espouses and defends.
