Since the mid-1960s, an increasingly large number of people, trained in the humanities and social sciences, have come to devote their professional lives to producing policy advice. This is a global phenomenon, although until recently the intensification of activities associated with policy advising has been most pronounced in the United States. As government demand for well-trained policy analysts and advisors has risen, universities have sought to provide relevant graduate-level training.
