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.

Cold Fusion Prediction Markets – [HISTORY]

Political Forecasting: Justin Wolfers vs. Nate Silver

Andrew Gelman nailed it:

In summary, &#8220-momentum&#8221- can exist, but the places where you&#8217-ll see it is in races where current public opinion is out of step with best predictions. The mere information that a race has a 5-point swing is not enough to predict a future shift in that direction. As Nate emphasizes, such a prediction is only appropriate in the context of real-world information, hypotheses of &#8220-factors above and beyond the direction in which the polls have moved in the past.&#8221-

Pollster John Zogby attacks statistician Nate Silver. – You take other peoples polls, compare records for predictions, add in some purely arbitrary (and not transparent) weights, then make your own projections and rankings.

Be Honest.

Understand That There&#8217-s Much More to Being a Good Pollster.

Appreciate Innovation.

Do Some Polling.

Nate Silver responds.

UPDATE: Prof Andrew Gelman&#8217-s take.
