As a seasoned union bargaining team member, I can verify that Carl's strategy is the least effective way to bargain. The first, crucial step in effective negotiation is to identify mutual interests; then the involved parties can work on how those mutual interests can be achieved.
In my own bargaining experience and according to a large pile of bargaining research, this interest-based approach is far more effective than Carl's "start out with an extreme position and horsetrade from there" approach.
