Standardly, the decision procedure that full rule-consequentialism endorses is the one that it would be best for society to accept. The qualification “standardly” is needed because there are versions of rule-consequentialism that let the rules be relativised to small groups or even individuals (D.E. Miller 2010; Kahn 2012).  And act-consequentialism insists upon the decision procedure it would be best for the individual to accept. So, according to act-consequentialism, since Jack’s and Jill’s capacities and situations may be very different, the best decision procedures for Jack to accept may be different from the best decision procedure for Jill to accept.  However, in practice act-consequentialists typically ignore for the most part such differences and endorse the above rule-consequentialist decision procedure (Hare 1981, chs. 2, 3, 8, 9, 11; Levy 2000).
