Handbook of Professional Ehtics for Psychologist, designed to fill a gap in the literature on professional ethics for psychologists, covers topics typically neglected in existing books, being more radical and controversial than much of the literature in this area. Rather than take ethical pronouncements associated with some organizations as dogma not to be questioned but simply understood and observed, the editors of this Handbook have encouraged a questioning, critical attitude. Handbook of Professional Ehtics for Psychologist is therefore in part an attempt to push harder on the ethical impulse in psychologists, pushing beyond 'comfort zones' to encourage positions of moral leadership.
