Economics & Reality
If you have read any economics literature, you know that for all decision making it assumes that the decision maker is a "rational man". Well, I don't think many decisions are made based on rationality. Emotion is a much powerful force than rationality and plays bigger role in decision making than rationality. Now, think about leadership and inspiring people. A good leader must connect with people at an emotional level to inspire them. Think Gandhi, Martin Luther King, and others.
