Livre d'Or

Robinson and others do support that last step, which I agree is not trivial; it is known that in some of the places that have legislated there have been significant behavioural changes, more generally that legislation of various flavours has produced a wide range of behavioural outcomes... but it never seems to work, for all that.

So I'd say it's more as if governments keep legislating homeopathy. After a while one has to conclude it's not because people don't take their sugar pills, especially if we know full well in some places they do, but because they just don't do anything.
