Is democratic leadership more effective than directive?

Democratic leadership is more effective than directive simply because it targets different aspects of human interactions besides giving and following orders. In democratic leadership, follower/employee feels cofindent enough to give some suggestion or opinion, that suggestion might be a very good one and eventually cause a prosperity of the whole organization. One mind cannot outsmart the many because nobody thinks identically. Ideas and constructive arguments are the best way to come up with a plan that will be the most efficient one. That is what directive leadership lacks.
