A scientific concept may have different systems of terminology associated with it, such that an internet or journal search for a given term misses important results associated with other terms that the searcher did not know about. Furthermore, there may be no links or mutual citations whatsoever between these fields. They may be in direct competition and therefore as silent as possible about one another. Thus, care should be taken to ensure that “comprehensive” surveys of an academic field on global risk are truly comprehensive.
