I don't think it's as objective as you think. There are many circumstances where someone might make a completely rational decision while still being utterly wro

  It depends on the definition of "rational". A serviceable but vacuous definition is "the procedure by which a decision is reached." Note that it is vacuous in that it imposes no constraints (not even repeatability/consistency), so anything that results in a decision fits the definition. It is serviceable because if you want a better definition, you have to argue deviations/changes - eg consistency. You'll find it to be a choice, not a requirement. Eg: Batman's Joker behaves according to his rules. The end result may be unpredictable, but that doesn't mean the decision process doesn't follow his rules.

  I didn't list "always succeeds" as a standard for rationality. I said, "chances they say are fifty-fifty turn out like they expected fifty percent of the time." If someone ascribes an 80% chance to each of 1000 possible events, and 800 of them happen, they are almost certainly rational.
