I disagree. Suppose you have an election with 3 candidates that runs every year. If you predict candidate A win at 33% confidence, but that candidate gets elected every year, your calibration will be way off. Calibration is about aggregating, so you can't really cheat it. Your 33% prediction has to be right 33% of the time - it's really hard to fake that.

Maybe I'm misunderstanding your position, though.
