If people were fair, reasonable, logical, and rational no matter what
the topic or incentive context, well then they would just agree all the
time about most everything, and bets would be few and of little use.
The whole reason that betting markets are interesting is that people
are not usually reasonable, and so the incentives of a bet can make them
more reasonable.  But if people are usually unreasonable we can't just
give them random topics and expect them to judge fairly.  We have to
be selective and pick topics and contexts where even unreasonable people
would find it hard to judge very unfairly.

Before a horse race, it is easy to deceive yourself about which is the
better horse.  Picking random judges then, and they might easily make
biased judgments that favor themselves (like favoring the horse from
their state or with a name they like.)  After the race it is much harder
to deceive yourself about who won the race.  So, we can give people
incentives to be honest before the race by having them bet on what judges
will say afterward about who won the race.
