One way to measure open-mindedness is to test for close-mindedness, and then take the converse. A subject for our measurement can be asked if he views certain proposals as impossible. By impossible I do not mean mathematically impossible, but so unlikely as to be considered absurd. Belief in impossibility is a sign of close-mindedness, because it reflects the unwillingness of the subject to be "receptive" to the possibility. | One way to measure open-mindedness is to test for close-mindedness, and then take the converse.
