After years of pretending being a prediction market consultant, Robin Hanson finally confesses nobody has ever cared about his stuff. – [LINK]

The Emperor of enterprise prediction markets is naked.

Robin Hanson:

I can confirm that this disinterest is real. For example, when I try to sell firms on internal prediction markets wherein employees forecast things like sales and project completion dates, such firms usually don’t doubt my claims that such forecasts are cheap and more accurate. Nevertheless, they usually aren’t interested.

The other take about forecast accuracy.

If prediction markets are such a powerful tool, then why arent we able to use them to solve [INSERT YOUR FAVORITE WORLD PROBLEM HERE]?

Justin Wolfers is asked the question, but I would have a different answer than his.

The reason prediction markets are not widely used in business is that their many boosters (Robin Hanson, James Surowiecki, Justin Wolfers, etc.) have exaggerated their usefulness. Just because they are objective in their wisdom does not mean that they are very useful.

Objectivity is over-rated. This is a painful lesson for the handful of young startups who swallowed the prediction market myth. Next step: the dead pool.
