Herodotus says of the Persians (http://www.gutenberg.org/cache/epub/2707/pg2707.txt)

To wine-drinking they are very much given, and it is not permitted for a man to vomit or to make water in presence of another. Thus do they provide against these things; and they are wont to deliberate when drinking hard about the most important of their affairs, and whatsoever conclusion has pleased them in their deliberation, this on the next day, when they are sober, the master of the house in which they happen to be when they deliberate lays before them for discussion: and if it pleases them when they are sober also, they adopt it, but if it does not please them, they let it go: and that on which they have had the first deliberation when they are sober, they consider again when they are drinking.

So drunk self and sober self form a quorum by referee? That's going to be exploitable and slow.

It makes sense if you think about it. If you feel the same way about a thing when your emotions are at their worst/most uninhibited, at their best/most shrewd, and when they’re most vulnerable/scrutinized, it’s a pretty good sign they’re sincere.

Sure its pretty balanced and conservative but you forfeit any potential for rapid action, privacy and self-determination. I don't think the best writers write by quorum and referee.

The quote referred to this process for “the most important of their affairs”. For writing, surely that would mean sleeping on and vetting big new ideas, rather than the entire process?
