Don since I still remember your contributions to the old Iraq war thread I'd be interested in knowing how you currently view geopolitics.
Well, ever since I watch "A Beautiful Mind" and learned that it was based on a true story I have become interested in game theory and its implications. At the end of this post I'll put up an article that I consider germane to the conversation. Also, I should state up front that my geopolitical views are currently in limbo, as it takes a while to build a new perspective after the old "house of cards" one has created comes crashing down. Basically, I'm still trying to "figure things out", but this doesn't mean that I haven't refuted much of what I use to believe.
As someone who shared and still holds some of your old 'evil Don' assumptions.
1. The cultural superiority of western civilisation over all others.
I think superior is the wrong term to use because it leads to a classical line of reasoning in regards to geo-political competition which need not exist. We are economically, institutionally, and politically more advanced than the other cultures of the world. This doesn't mean that "our way" has to be spread the world over. I'm starting to believe that it is very difficult, if not impossible, to try and force upon a people cultural changes which took western civilization centuries to transition through. Cultural evolution is a notoriously slow process.
Having a more advanced culture also doesn't mean that we are even remotely close to the appex of cultural evolution. Humanistic principles have made inroads, but religion is still prevelent through out much of the western world. Inotherwords, we are still a part of this world and we still possess the same flaws in our nature that every other culture possesses. We are not above the fray. You have to allow for the possibility that we are part of the problem and not just part of the solution.
2. the need for a credible threat of force as a primary instrument of foreign policy.
A yeah, but we already possess a very credible threat of force with the thousands of ICBM's we possess. The US spends more on defense than the next 15 nations after it combine, that is starting to seem like a little bit of over kill to me. I still feel that having a sufficient conventional military threat is necessary, but actually using military forces creates a great deal of backlash in the international community, as is evident by the second Gulf War. Throwing our weight around creates a lot of animosity, suspicion and anger.
And what do we accomplish by being "proactive" militarily? It's starting to look like we've given ourselves an occupation with no exit strategy. Occupations are costly and there is no guarantee of success. Also, the prohibitive cost of using military force (and the subsequent occupation) allows for the temptation to use the control we have gained to exact informal restitutions to pay for the costs incurred. This further perpetuates the cyclical nature of resentment, anger and violence.
I'm not against having a credible threat of force, but I am beginning to better understand the costs of going forward with the threat. I think occupations are something that should be avoided if at all possible.
3. some fairly darwinistic ideas about how progress in general is achieved
I'm going to attach a little piece on game theory which I think modifies the concept of social darwinism to the point where it is no longer recognizable.
Regarding ethics and atheism, my own sense of morality has always stemmed from the fact that I consider self-awareness to be an end in and of itself.
Could you ellaborate on this point?
Game Theory
Avinash Dixit, John J. F. Sherrerd '52 University Professor of Economics at Princeton University, is John Nash's colleague and friend. He has taught economics courses on games of strategy, and written books on the subject for students and for the general audience.
Here Prof. Dixit explains game theory and its impact on situations we encounter every day. "If Nash got a dollar for every time someone wrote or said 'Nash equilibrium,'" Dixit has said, "he would be a rich man."
Game theory studies interactive decision-making, where the outcome for each participant or "player" depends on the actions of all. If you are a player in such a game, when choosing your course of action or "strategy" you must take into account the choices of others. But in thinking about their choices, you must recognize that they are thinking about yours, and in turn trying to take into account your thinking about their thinking, and so on.
It would seem that such thinking about thinking must be so complex and subtle that its successful practice must remain an arcane art. Indeed, some aspects such as figuring out the true motives of rivals and recognizing complex patterns do often resist logical analysis. But many aspects of strategy can be studied and systematized into a science -- game theory.
A Theory is Born
This science is unusual in the breadth of its potential applications. Unlike physics or chemistry, which have a clearly defined and narrow scope, the precepts of game theory are useful in a whole range of activities, from everyday social interactions and sports to business and economics, politics, law, diplomacy and war. Biologists have recognized that the Darwinian struggle for survival involves strategic interactions, and modern evolutionary theory has close links with game theory.
Game theory got its start with the work of John von Neumann in the 1920s, which culminated in his book with Oskar Morgenstern. They studied "zero-sum" games where the interests of two players were strictly opposed. John Nash treated the more general and realistic case of a mixture of common interests and rivalry and any number of players. Other theorists, most notably Reinhard Selten and John Harsanyi who shared the 1994 Nobel Memorial Prize with Nash, studied even more complex games with sequences of moves, and games where one player has more information than others.
The Nash Equilibrium
The theory constructs a notion of "equilibrium," to which the complex chain of thinking about thinking could converge. Then the strategies of all players would be mutually consistent in the sense that each would be choosing his or her best response to the choices of the others. For such a theory to be useful, the equilibrium it posits should exist. Nash used novel mathematical techniques to prove the existence of equilibrium in a very general class of games. This paved the way for applications. Biologists have even used the notion of Nash equilibrium to formulate the idea of evolutionary stability. Here are a few examples to convey some ideas of game theory and the breadth of its scope.
The Prisoner's Dilemma
In Joseph Heller's novel Catch-22, allied victory in World War II is a foregone conclusion, and Yossarian does not want to be among the last ones to die. His commanding officer points out, "But suppose everyone on our side felt that way?" Yossarian replies, "Then I'd certainly be a damned fool to feel any other way, wouldn't I?"
Every general reader has heard of the prisoner's dilemma. The police interrogate two suspects separately, and suggest to each that he or she should fink on the other and turn state's evidence. "If the other does not fink, then you can cut a good deal for yourself by giving evidence against the other; if the other finks and you hold out, the court will treat you especially harshly. Thus no matter what the other does, it is better for you to fink than not to fink -- finking is your uniformly best or 'dominant' strategy." This is the case whether the two are actually guilty, as in some episodes of NYPD Blue, or innocent, as in the film LA Confidential. Of course, when both fink, they both fare worse than they would have if both had held out; but that outcome, though jointly desirable for them, collapses in the face of their separate temptations to fink.
Yossarian's dilemma is just a multi-person version of this. His death is not going to make any significant difference to the prospects of victory, and he is personally better off alive than dead. So avoiding death is his dominant strategy.
John Nash played an important role in interpreting the first experimental study of the prisoner's dilemma, which was conducted at the Rand Corporation in 1950.
Real-World Dilemmas
Once you recognize the general idea, you will see such dilemmas everywhere. Competing stores who undercut each other's prices when both would have done better if both had kept their prices high are victims of the dilemma. (But in this instance, consumers benefit from the lower prices when the sellers fink on each other.) The same concept explains why it is difficult to raise voluntary contributions, or to get people to volunteer enough time, for worthwhile public causes.
How might such dilemmas be resolved? If
the relationship of the players is repeated over a long time horizon, then the prospect of future cooperation may keep them from finking; this is the well-known tit-for-tat strategy. A "large" player who suffers disproportionately more from complete finking may act cooperatively even when the small fry are finking. Thus Saudi Arabia acts as a swing producer in OPEC, cutting its output to keep prices high when others produce more; and the United States bears a disproportionate share of the costs of its military alliances. Finally, if the group as a whole will do better in its external relations if it enjoys internal cooperation, then the process of biological or social selection may generate instincts or social norms that support cooperation and punish cheating. The innate sense of fairness and justice that is observed among human subjects in many laboratory experiments on game theory may have such an origin.
Mixing Moves
In football, when an offense faces a third down with a yard to go, a run up the middle is the usual or "percentage" play. But an occasional long pass in such a situation is important to keep the defense honest. Similarly, a penalty kicker in soccer who kicks exclusively to the goalie's right, or a server in tennis who goes exclusively to the receiver's forehand, will fare poorly because the opponent will anticipate and counter the action. In such situations it is essential to mix one's moves randomly, so that on any one occasion the action is unpredictable.
Mixing is most important in games where the players' interests are strictly opposed, and this happens most frequently in sports. Indeed, recent empirical studies of serving in tennis grand slam finals, and penalty kicks in European soccer leagues, have found the behavior consistent with the theory.
Commitments
Greater freedom of action seems obviously desirable. But in games of bargaining that need not be true, because freedom to act can simply become freedom to concede to the other's demands. Committing yourself to a firm final offer leaves the other party the last chance to avoid a mutually disastrous breakdown, and this can get you a better deal. But a mere verbal declaration of firmness may not be credible. Devising actions to make one's commitments credible is one of the finer arts in the realm of strategic games. Members of a labor union send their leaders into wage bargaining with firm instructions or mandates that tie their hands, thereby making it credible that they will not accept a lower offer. The executive branch of the U.S. government engaged in international negotiations on trade or related matters can credibly take a firm stance by pointing out that the Congress would not ratify anything less. And a child is more likely to get the sweet or toy it wants if it is crying too loudly to hear your reasoned explanations of why it should not have it.
Thomas Schelling pioneered the study of credible commitments, and other more complex "strategic moves" like threats and promises. This has found many applications in diplomacy and war, which, as military strategist Karl von Clausewitz told us long ago, are two sides of the same strategic coin.
Information and Incentives
Suppose you have just graduated with a major in computer science, and have an idea for a totally new "killer app" that will integrate PCs, cell phones, and TV sets to create a new medium. The profit potential is immense. You go to venture capitalists for finance to develop and market your idea. How do they know that the potential is as high as you claim it to be? The idea is too new for them to judge it independently. You have no track record, and might be a complete charlatan who will use the money to live high for a few years and then disappear. One way for them to test your own belief in your idea is to see how much of your own money you are willing to risk in the project. Anyone can talk a good game; if you are willing to put enough of your money where your mouth is, that is a credible signal of your own true valuation of your idea.
This is a game where the players have different information; you know the true potential of your idea much better than does your prospective financier. In such games, actions that reveal or conceal information play crucial roles. The field of "information economics" has clarified many previously puzzling features of corporate governance and industrial organization, and has proved equally useful in political science, studies of contract and tort law, and even biology. The award of the Nobel Memorial Prize in 2001 to its pioneers, George Akerlof, Michael Spence, and Joseph Stiglitz, testifies to its importance. What has enabled information economics to burgeon in the last twenty years is the parallel development of concepts and techniques in game theory.
Aligning Interests, Avoiding Enrons
A related application in business economics is the design of incentive schemes. Modern corporations are owned by numerous shareholders, who do not personally supervise the operations of the companies. How can they make sure that the workers and managers will make the appropriate efforts to maximize shareholder value? They can hire supervisors to watch over workers, and managers to watch over supervisors. But all such monitoring is imperfect: the time on the job is easily monitored, but the quality of effort is very difficult to observe and judge. And there remains the problem of who will watch over the upper-level management. Hence the importance of compensation schemes that align the interests of the workers and managers with those of the shareholders. Game theory and information economics have given us valuable insights into these issues. Of course we do not have perfect solutions; for example, we are just discovering how top management can manipulate and distort the performance measures to increase their own compensation while hurting shareholders and workers alike. This is a game where shareholders and the government need to find and use better counterstrategies.
From Intuition to Prediction
While reading these examples, you probably thought that many of the lessons of game theory are obvious. If you have had some experience of playing similar games, you have probably intuited good strategies for them. What game theory does is to unify and systematize such intuitions. Then the general principles extend the intuitions across many related situations, and the calculation of good strategies for new games is simplified. It is no bad thing if an idea seems obvious when it is properly formulated and explained; on the contrary, a science or theory that takes simple ideas and brings out their full power and scope is all the more valuable for that.
I am much less confident of my ability to understand and argue my positions now, then when I was a neo-con, but I am much more confident that I am at least moving in the right direction. As Laz always says, politics is religion and religion is politics. I now agree with this notion and am trying to be ever so careful with the assumption I make. One's arguments are only as strong as its weakest link.
Nice to talk Utna, we need to chat real time, but the I've been having problems with the chat room lately.
Sincerely
