This document discusses tolerance for ambiguity and its effect on communication. It defines ambiguity as permitting more than one interpretation, as opposed to vagueness. Some personality types see ambiguity as an opportunity, while others view it as a threat. The document also describes four modes of leadership based on differing degrees of ambiguity tolerance as defined by Wilkinson's Ambiguity Advantage model. Finally, it concludes that the best communication approach depends on the situation, and knowing one's own tolerance for ambiguity can help with effective communication.
