Minimizing the entropy gets you as close as possible to determinism.

BTY I suggest random implicit approval as the default lottery.

As for repeated referendae, if all factions used that option  then their
favorite would be adopted with a frequency predicted by the consensus
lottery, assuming preferences stay the same over the time period of the
repetition; it would backfire if it annoyed the voters.
