This almost seems too obvious to mention in one of Robin's threads, but I'll go ahead anyway: success on prediction markets would seem to be an indicator of rationality and/or luck. Your degree of success in a game like HubDub may give some indication as to the accuracy of your beliefs, and so (one would hope) the effectiveness of your belief-formation process.

I would expect success in a prediction market to be more correlated with amount of time spent researching than with rationality. At best, rationality would be a multiplier to the benefit gained per hour of research; alternatively, it could be an upper bound to the total amount of benefit gained from researching.
