We have a strange idea, which seems apply almost exclusively to economics, politics and business, that experts are good at predictions.

In reality almost everyone is better at making predictions than the experts are.

There are two things happening here. One is that expertise isn't based on predictive ability, but on following the party line. It's a perfectly soviet system, where talking rubbish gets you immense rewards.

The other is the corollary that decisions are made by the people who are least competent to run it - because the goal isn't to make intelligent decisions, it's to maintain power differentials for as long as possible.  

If you had a modelling and prediction game you could find individuals who had a talent for intuitive modelling and insight and give them something useful to do. They wouldn't necessarily have to know how to build models out of differential equations, but they would have a better than usual batting average when it came to being right about the future.

These people would potentially be very, very valuable. Currently I suspect most of them are wasted in jobs which aren't ideally suited to their talents.
