Leadership understands there are competing forces on the ends of many continua, e.g. flexibility vs. rules, emotional intelligence vs. IQ, and diffusion of responsibility vs. accountability. Each could be characterized, in general, as relationship vs. task, respectively.
Leadership decisions are rarely black or white; decisions are best addressed by gathering all of the information in order to make decisions that lie on the continua, not at their extremes.
DU does not gather information (they don't formulate any questions b/c they erroneously belief they have all of the information), and as a result, their decisions are suboptimal.
