This seems the most reasonable approach to me, although as I wrote I don't
see why it has to be enforced by courts. Ultimately, if IF proves its
value the system should be self enforcing.

I suspect it would be hard to find this much certainty on most
controversial issues. So this rule would probably not be used much.

Choosing that objective function would be a massive political battle.
Chances are people would want to change it from year to year, too, as
their concerns change. Education is the big issue one year; the next
it's crime, the next it's taxes, then it's growth. People wouldn't want
to turn their political decisions over to a formula that they couldn't
change as needed.
But aside from these issues, the more important first step is to
have some way for IF to be tested. I don't think the online game at
www.ideosphere.com has had very meaningful results (only a few dozen
players are really active at any one time), and my sense from playing
the game is that the predictions haven't been noticeably more accurate
than those from other sources.
If there is to be significant support for using IF in the political
process then it must be given an opportunity to prove its worth. I don't
see that happening any time soon.
