It's a good question. There are several kinds of answers, two of which I allude to but don't go into a lot of detail. The answers based off of peer reviewed research can be found in the article in Science that I quote. There is also the answer based off a sort of existence proof—so far, even when this is been done at a high level around extremely controversial and impactful issues, this has not appeared to be a significant problem.

To be clear, the process that I am describing there is not some newfangled idea that I just dreamed up. It's something that has been used by France, Ireland, South Korea, even the EU as whole, is likely to be institutionalized as part of the governance of these organizations. It's just fairly new so not that many people have heard about it.
