How about this? Pundits on broadcast radio and T.V. have to put up a cash bond to back their prediction…
Should their prediction be wrong, the cash bond goes to an integrity-in-broadcast charity.
The cash amounts of the bonds perhaps variable, be a tricky scale to work out.
Also the issue of general falsities, like hartley brewer I heard claiming Russian casualties were ten times that of Ukraine. I suspect that is false, of course whose stats are we using, will the truth ever be known whichever side wins? Lie A or Lie B eh!
