The Carol Syndrome "Carol's perception that she scares men away is not a delusion after all. … It is not a matter of bad luck but a collateral effect of interactive rationality. A paradoxical consequence is that Carol's attractiveness acts as a repellent." Game theory (mis?)applied to dating. [more inside]

Braess' paradox and the price of anarchy [PDF]: "We had three tunnels in the city and one needed to be shut down. Bizarrely, we found that car volumes dropped. ... We discovered it was a case of Braess' paradox, which says that by taking away space in an urban area you can actually increase the flow of traffic, and, by implication, by adding extra capacity to a road network you can reduce overall performance."

According to the Global Extinction Awareness System (GEAS, by the Institute For the Future) - a simulation based on "the worlds’s first massively multiplayer forecasting game" - by the year 2042 AD there is a potentially terminal combination of five so-called “super-threats” which represent a collision of environmental, economic, and social risks. Acting together, the five super-threats may irreversibly overwhelm homo sapiens ability to survive. Spokesperson for United Nations Secretary General “We are grateful for GEAS’ work, and we treat their latest forecast with seriousness and profound gravity.”[[press release]]. The game runs from Oct.8 to Nov. 6, players wanted.

An online auction site called Swoopo, once called TeleBid, has hit upon an ingenious way to make money. They are an auction site not entirely unlike Ebay - but using a different auction scheme. Where EBay uses a slightly modified Vickrey auction system, Swoopo uses an auction system based on the "Dollar Auction" game - with interesting results. [more inside]

The Monty Hall Problem has struck again, and this time it’s not merely embarrassing mathematicians. If the calculations of a Yale economist are correct, there’s a sneaky logical fallacy in some of the most famous experiments in psychology." The NY Times' John Tierney reports on new research into cognitive dissonance as examined through the famous Monty Hall Problem. [A previous MetaFilter thread about the Monty Hall Problem: Let's Make A Deal!]

The Paisley Underground. From about 1982 to 1985, the Los Angeles club scene featured a bunch of guitar bands on the verge of being the next big thing, including The Dream Syndicate, Green on Red, The Long Ryders, The Rain Parade, Game Theory (later known as The Loud Family) and, of course, The Bangles (the only ones who managed to actually become a big thing). Michael Quercio of The Three O'Clock and Salvation Army inadvertently named the scene "Paisley underground" when he made an off handed joke during a radio interview. Most of the bands are now, to borrow a phrase from Game Theory leader Scott Miller, languishing in national obscurity, as opposed to local obscurity.

"He asks each of them to write down...any dollar integer between 2 and 100 without conferring together. If both write the same number...he will pay each of them that amount. But if they write different numbers, he will ... pay both of them the lower number along with a bonus and a penalty--the person who wrote the lower number will get $2 more...and the one who wrote the higher number will get $2 less.... For instance, if Lucy writes 46 and Pete writes 100, Lucy will get $48 and Pete will get $44."What amount would you choose? And what does your answer tell us about the limits of Game Theory?
Game Theory at the movies. The Princess Bride demonstrates the use of common knowledge, Butch Cassidy laments pareto equilibrium, and Swingers is an example of pooling equilibrium. Though no longer on the site, you can still see the most involved rock, paper, scissors game ever filmed [.mov].

An evolutionary basis for altruism. These findings suggest that true altruism, far from being a maladaptation, may be the key to our species' success by providing the social glue that allowed our ancestors to form strong, resilient groups. Sharing isn't just caring, it's surviving.

Tit-for-tat dethroned in iterated prisoner's dilemma competition! But it might not work so well in RL, and what if you threw in QM? :D

"We plan to put Beauty to sleep by chemical means, and then we’ll flip a fair coin. If the coin lands Heads, we will awaken Beauty on Monday afternoon and interview her. If it lands Tails, we will awaken her Monday afternoon, interview her, put her back to sleep, and then awaken her again on Tuesday afternoon and interview her again. The (each?) interview is to consist of the one question : what is your credence now for the proposition that our coin landed Heads? When awakened (and during the interview) Beauty will not be able to tell which day it is, nor will she remember whether she has been awakened before. She knows about the above details of our experiment. What credence should she state in answer to our question?"
In light of the recent thread on the Monty Hall problem, here's a probability puzzle that's even more mind-bending: the Sleeping Beauty problem. Some people say the answer is 1/2. Some people say the answer is 1/3. Some people say there is no answer. Papers have been written which can't resolve this one.

Game Theories: Are these virtual worlds the best place to study the real one? The Gross National Product of EverQuest, measured by how much wealth all the players together created in a single year inside the game. It turned out to be $2,266 U.S. per capita. By World Bank rankings, that made EverQuest richer than India, Bulgaria, or China, and nearly as wealthy as Russia. (by Clive Thompson)

Problems in infinite decision theory [pdf]. You are in hell and facing an eternity of torment, but the devil offers you a way out, which you can take once and only once at any time from now on. Today, if you ask him to, the devil will toss a fair coin once and if it comes up heads you are free (but if tails then you face eternal torment with no possibility of reprieve). You don’t have to play today, though, because tomorrow the devil will make the deal slightly more favourable to you (and you know this): he’ll toss the coin twice but just one head will free you. The day after, the offer will improve further: 3 tosses with just one head needed. And so on (4 tosses, 5 tosses, ….1000 tosses …) for the rest of time if needed. So, given that the devil will give you better odds on every day after this one, but that you want to escape from hell some time, when should accept his offer? More discussion here.

The Ultimate Game. Game theory was applied extensively by US foreign policy-makers during the Cold War, and many would credit those "moves" with the triumph of the West. But can it work now? Are rogue states and terrorists "rational actors?" Are we seeing a classic two-player game playing out with the US and Iraq? What does it even mean to "win" in the post-Soviet era? If these theories interest you, try these online simulations.

Civil War: Political Violence and Robust Settlements -- an article from the Santa Fe Institute Bulletin about game theoretical approaches combined with on the ground field studies to analyze war and conflict. The article centers around work (Forging Democracy From Below: Insurgent Transitions in South Africa and El Salvador | Insurgent Collective Action and Civil War in El Salvador) done by Elisabeth Jean Wood, an NYU professor of political science with a background in physics. "The reason to study violence and suffering," says Wood, "is to understand its origins, processes, andâ?"ideallyâ?"to contribute to its cessation."

The Nash equilibrium
So at the present time I seem to be thinking rationally again in the style that is characteristic of scientists. However this is not entirely a matter of joy as if someone returned from physical disability to good physical health. One aspect of this is that rationality of thought imposes a limit on a person's concept of his relation to the cosmos....from John F. Nash Jr.'s autobiography for the 1994 Nobel Prize for Economics.
