A second element of the cultural structure defines, regulates and controls the acceptable modes of reaching out for these goals.  Every social group invariably couples its cultural objectives with regulations, rooted in the mores of institutions, of allowable procedures for moving toward these objectives.  These regulatory norms are not necessarily identical with technical or efficiency norms.  Many procedures which from the standpoint of particular individuals would be most efficient in securing desired values—the exercise of force, fraud, power—are ruled out of the institutional area of permitted conduct.  At times, the disallowed procedures include some which would be efficient for the groups itself—e.g., historic taboos on vivisection, on medical experimentation, on the sociological analysis of “sacred” norms—since the criterion of acceptability is not technical efficiency but value-laden sentiments (supported by most members of the group or by those able to promote these sentiments through the composite use of power and propaganda).  In all instances, the choice of expedients for striving toward cultural goals is limited by institutionalized norms (1968, p. 187).
