I did all my predictions last night immediately after the email showed up, so that meant I got to place a lot of bets at 50/50 odds :)
(Then I recorded everything privately in PredictionBook. No point in leaving my predictions trapped on their site.)
Interface-wise, I don't like it at all. I'm still not sure what exactly I am betting at or with, compared to PB with straight probabilities or Intrade with share prices.
Have you entered any comments on your predictions at the GJ site? (You're supposed to enter a minimum number of comments over one year, and also a minimum number of responses to others' comments. My understanding is that this will in time be run as a team game, with team play conventions.)
From my first experiences, I'm assuming the scoring will be pretty much as with PB.com - based on probability. Their model seems to be calibration/resolution rather than the visual "slope" representation.
A tournament is currently being initiated by the Intelligence Advanced Research Project Activity (IARPA) with the goal of improving forecasting methods for global events of national (US) interest. One of the teams (The Good Judgement Team) is recruiting volunteers to have their forecasts tracked. Volunteers will receive an annual honorarium ($150), and it appears there will be ongoing training to improve one's forecast accuracy (not sure exactly what form this will take).
I'm registered, and wondering if any other LessWrongers are participating/considering it. It could be interesting to compare methods and results.
Extensive quotes and links below the fold.
A general description of the expected benefits for volunteers:
Could that be any more LessWrong-esque?
