I've been wondering if it's not the other way round, the Good Judgement project copying Inkling Market's questions? What info do you have that leads you to think the copying was in the direction you assume?
My evidence for the other way round is that the Brent question has a starred footnote which is present on IM but not on GJ, while the star is in the text of the GJ question.
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?
