Why does impasse occur in mediation? In my experience as a commercial mediator, impasse most often flows from a combination of cognitive biases and flawed risk assessments.
The human mind works in mysterious ways. Research in psychology and economic behaviour continues to uncover myriad ways in which the mind deviates from norms or rationality in judgement. Daniel Kahneman’s Thinking Fast and Slow is required reading for commercial mediators. Even a glance at the Wikipedia entry for List of Cognitive Biases will be cause for caution. Some of these cognitive biases are frequently evident in mediated negotiations.
Disputing parties will want to carefully consider their BATNA as they prepare for a mediated negotiation. Reconsideration requires them to accurately and realistically assess what will happen if settlement efforts fail. Decision Tree Analysis is a helpful tool for probing a parties’ BATNA.
All too often, though, people are overly optimistic in their use of the Decision Tree tool. The result: plaintiffs value their case too highly, and defendants severely undervalue their exposure. Complete preparation for mediation will see lawyers and their clients considering other scenarios in which the possible outcomes at trial are less favourable than their initial assessment.
