Critics of the concept argue that its vagueness undermines its effectiveness, that it has become little more than a vehicle for activists wishing to promote certain causes, and that it does not help the research community understand what security means or help decision makers to formulate good policies.

Thus understood, human security would no longer be the vague amorphous add-on to harder edged areas of security such as military security or state security.'
