“…Despite Herring's call, however, the public interest as a guiding precept for American PA has remained problematic due to its ambiguous meaning, as noted above. In an influential critique, Schubert (1957) concluded that ''the public interest notion is close to useless in the development [of PA as] a true social science'' (Goodsell, 1990, p. 98). Through the turbulent 1960s and 1970s, the public interest as a central theme became ''more clouded, more fragmented, less easy to know and act upon and, hence, it became a subject few public administration theorists addressed'' (Stillman, 1985, p. 114).…”
