Early 20th century populism took that away. It also meant that the states now have no representation in the federal legislature, which led to an almost immediate federal takeover of basically everything.
You could also have one body of the legislature (the US Senate? The House of Lords?) selected by Sortition: https://en.wikipedia.org/wiki/Sortition
In political voting the problem is not a lack of information- everyone has a strong opinion about everything already and putting them in small groups would just result in unproductive bickering.
There’s a hierarchical electoral system where those at the bottom of the group votes for the next position up.
If one will say "lets vote for X" and the rest will say "yea whatever".
They did not reach any consensus as the discussion did not really happen.
Only way to make democracy work is to let ppl who care reach consensus.
I seriously doubt the wisdom of a crowd goes up when the total crowd size shrinks to 10. I suspect it plummets.
This does call into question the notion of a multiple-jury trial (maybe videoconferenced in, where the individual juries do not interact with each other). Based on this study's findings, it would appear that juries might get their verdicts wrong less frequently with this system.
Imagine if the first OJ trial or Trayvon Martin trial had been before multiple juries; would society have been better off if the results were less dependent on the biases of juries small enough to be cherry-picked?
Wisdom of the Crowd vs one person = good
Wisdom of the crowd vs tiny groups 4+ = bad
