A simple laboratory method of demonstrating the effects of different types of leadership is to have class members individually rank their preferences for 12 presidential nominees. A day later the students are divided into groups of 5 and select group leaders, who are separately instructed to obtain group rankings, either by supervising or by participating in group discussion and drawing out all opinions. A day later, individual rankings are again obtained. Comparison of initial and final individual rankings shows participatory leadership to be more effective in changing attitudes, in producing group agreement, and in making the task more interesting.
