Abstract
Considers whether rule‐consequentialism is undermined by the unpredictability of the consequences of whole codes of rules. Argues that, where we can calculate that some alternative is better than the status quo, we press forward with reform, and that where we cannot calculate that some alternative code is better than the status quo, we should stick with the status quo. Concludes by considering how ideal codes have to compromise with extant conventions, and how rule‐consequentialism can support public goods.
