This negative impact takes place for several reasons: First, the establishment of such commissions will tend to reduce pressures for change. Second, the members of such commissions, by virtue of their socialization and training, are more adept at processing the language of the system than dealing with its substance. Third, commissions, by making recommendations for change, revise the language through which the system is conceptualized, which in effect legitimizes the system in its existing form. Commissions iterate and legitimize the status quo rather than promote system-wide change. The changes which do occur are only those which are necessary to insure that the system will remain stable. In an attempt to illustrate the arguments, excerpts from Corrections, published by the National Advisory Commission on Criminal Justice Standards and Goals (1973) are compared with Transactions, published by the National Congress on Penitentiary and Reformatory Discipline (1870).
