Ask Lemmy

You can do it several ways. Athens had anyone who wanted to from the city meet and interview the randomly chosen folks; if the group disliked them, they were removed from the pot and you drew again. Seems like a good fit when the job is comprehensible, and/or needs community backing. Similar in flavor to senate confirmation of appointees.

In juries, we have professionally licensed advocates and referee's who interview the randomly chosen, and they can reject folks for almost any reason they want. This seems like a good fit when we already have a big body of bureaucrats and managers who will need to work with these folks. Let them do the filtering.

For perpetually rolling positions, give the outgoing folks a small number of vetos on the next draw. They know what the job requires, and limiting the number of objections ensures against corruption.

There's also levers you can pull if we don't have a good way to judge competence. My favorites are to increase the number of people on the panel/jury/group, and provide larger budgets and opportunities for the group to get training. Just as congress (and courts) can pull in industry leaders, expert scientists, and decision makers, these decision making bodies should be able to do the same.
