Peacemaking: People have dozens of decision-making biases, and almost all favor conflict rather than concession
National leaders get all sorts of advice in times of tension and conflict. But often the competing counsel can be broken down into two basic categories. On one side are the hawks: They tend to favor coercive action, are more willing to use military force, and are more likely to doubt the value of offering concessions. When they look at adversaries overseas, they often see unremittingly hostile regimes who only understand the language of force. On the other side are the doves, skeptical about the usefulness of force and more inclined to contemplate political solutions. Where hawks see little in their adversaries but hostility, doves often point to subtle openings for dialogue.
Social and cognitive psychologists have identified a number of predictable errors (psychologists call them biases) in the ways that humans judge situations and evaluate risks. Biases have been documented both in the laboratory and in the real world, mostly in situations that have no connection to international politics. Pychological impulses incline national leaders to exaggerate the evil intentions of adversaries, to misjudge how adversaries perceive them, to be overly sanguine when hostilities start, and overly reluctant to make necessary concessions in negotiations. In short, these biases have the effect of making wars more likely to begin and more difficult to end.
None of this means that hawks are always wrong. One need only recall the debates between British hawks and doves before World War II to remember that doves can easily find themselves on the wrong side of history. More generally, there are some strong arguments for deliberately instituting a hawkish bias. It is perfectly reasonable, for example, to demand far more than a 50-50 chance of being right before we accept the promises of a dangerous adversary. The biases that we have examined, however, operate over and beyond such rules of prudence and are not the product of thoughtful consideration. Our conclusion is not that hawkish advisors are necessarily wrong, only that they are likely to be more persuasive than they deserve to be. Read more.
