It might be alleged that a
PhD reflects overspecialization that manifests itself as a lack of perspective; for example, a PhD might not adequately prepare one for careers in development, manufacturing, or technical management. In the corporate world, some PhD graduates have been criticized as being unable to turn theories into useful strategies and being unable to work on a team, although PhDs are seen as desirable and even essential in many positions, such as supervisory roles in research, especially PhDs in
biomedical sciences. Even in some college jobs, people can associate negative factors with the PhD, including a lack of focus on
teaching, overspecialization, and an undesirable set of professional priorities, often focusing on self-promotion. These forces have led both to an increase in some educational institutions hiring candidates without PhDs as well as a focus on the development of other doctoral degrees, such as the D.A. or
Doctor of Arts. Some employers have reservations about hiring people with PhDs in full-time, entry-level positions but are eager to hire them in temporary positions. Some argue that this reservation is rather a reaction associated with job insecurity, especially in situations where most of the company leaders hold lower qualifications than the PhD; as part of the wide phenomenon of
credential creep. ==See also==
