Furthermore, they have run this experiment with people before, and have been right every time. This is a paradox because there seem to be good arguments for both options. On the other hand, the money is already in the box, so you might as well take both. Is it rational to vote?
But people do vote. There are counter arguments that say that it is rational to vote.
See Voting as a rational choice: why and how people vote to improve the well-being of others by Aaron Edlin, Andrew Gelman, and Noah Kaplan, Rationality and Society, , vol 19 3 , pages — They argue that you should consider the benefit not just to the voter, but to the country.
While some people may use this reasoning to justify voting, it is not a good resolution to the paradox.

Thus it is rational to vote assuming that you believe that there are a significant number of rational voters. Besides resolving the paradox, this is also very close to the arguments that many people give for why you should vote, e. Lawrence H. Unfortunately paradoxically? The authors of these articles either ignore the fact that both criminals are rational or do not take this fact seriously. One wonders if these authors vote, recycle, refrain from littering, conserve water, stick to their word when entering into agreements with people that they won't deal with again, etc.
On Sunday evening a judge tells a condemned prisoner that they will be awakened and hanged on the morning of one of the following five days. The judge says that it will happen unexpectedly, i. So, Friday is ruled out. But then, by the process of elimination, so are Thursday, Wednesday, Tuesday, and Monday.
Of course, on Wednesday, the prisoner is hauled out of bed, much to their surprise, and hanged.
The resolution is to realize that there is a difference between being able to guarantee something will happen and it happening because you got lucky. The prisoner is correct that the judge cannot guarantee that the hanging will be unexpected. But, this does not prevent the judge from getting lucky. An analogy would be if the judge said that the prisoner would be hanged in the morning and it would not rain for the whole day of the hanging.
I have not seen this resolution anywhere else. Let me know if you see it somewhere. Resolutions of paradoxes should usually be short. If you need a whole book to explain your resolution, then it probably is not the correct resolution. Page published Section on Liar Paradox expanded Many references added The Three Cards Paradox. Consider three cards with the following three sentences: The sentence on the second card is true, and the sentence on the third card is false. Either the sentence on the first card is false, or the sentence on the third card is true.
The sentences on the first and second cards are both true. Since any member of the family plays randomly for the first rounds, they can't recognise themselves or formulate a reasonable response to random play and hence tend to get locked into mutual defection. While the paper is sophisticated and some results interesting, it is not until the end of the paper that any possible applications to human or animal behaviour are offered, and these applications, it must be said, are quite loosely coupled. Unfortunately, this volume is not completely without the "shoot first, ask questions later" method that sometimes plagues simulation: simulations are often technically interesting, but it is difficult to imagine them having any applications to a human or animal group because the initial conditions and other parameters are so specific that one can't see where they would arise naturally.
However, this volume comparatively rarely suffers from this fault, and is to be lauded for its emphasis on simulating and modelling issues that are deduced from questions about individual rationality, in contrast to less individualist models such as those based on replicator dynamics in evolutionary game theory which concern population-based evolution although these are certainly interesting and helpful models as well.
An excellent antidote to this problem is in the essay by Huberman and Glance. They borrow methods from statistical thermodynamics in which macro-level properties are reduced to the activity of lower level-units.
An analogy would be the attempt to explain wetness or solidity as a feature of water based on what is happening at the micro-level to the atoms in water molecules. Specifically, they discuss how different types of expectations about co-operation affect individual propensities to co-operate and how these expectations lead to group level dynamics, much like Schelling's segregation models The simulation models from Skyrms' chapter - which is itself is reprinted from his book - uses Aumann's idea of a correlated equilibrium to show how non-random pairings of players can lead to co-operation Aumann Two other papers are excellent, but don't quite fit the simulator's usual preference.
This essay covers, concisely but thoroughly, just about all of the relevant results on the Prisoner's Dilemma from economics, as well as partial discussion of results from Prisoner's Dilemma tournaments, and N-Person Prisoner's Dilemmas. Also perhaps somewhat outside the purview of standard simulation interests is an experimental study by Kollock which has subjects playing a Prisoner's Dilemma and examining the interaction effects between group identification manipulation and individual value orientations.
If one is interested to know whether what is simulated actually ever appears empirically, then more attention should be paid to experimental studies such as these, and the inclusion of this article in this volume is most welcome for that reason. At the beginning of this review I stated that there were many essays concerning the definition of practical reason also known as instrumental rationality that were sufficiently philosophical to be uninteresting to a social simulator namely, essays by Bratman, Churchland, Gauthier, Irvine, McClennen and de Sousa.
Where the essays by MacIntosh, Talbott and LaCasse and Ross concern whether individual rationality can explain or justify moral behaviour, these essays concern whether or not we have reason to be instrumentally rational. Such a philosophical question, whether rationality can be self-defeating may seem uninteresting, intractable or otherwise esoteric, but I believe it is worthy of attention, not least because recent simulations have in fact attempted to model the interaction between a reasoning, planning agent in a changing environment.
However, let me attempt to briefly pique the reader's interest in this topic.
With the exception of Churchland's essay, the essays by Bratman, Gauthier, Irvine, McClennen and de Sousa basically discuss what gives humans a reflective reason to be rational. In other words, we can ask "does the theory of expected utility recommend the theory of expected utility as a theory of rationality one should follow?
This is Kavka's "toxin puzzle". Here is how it is presented by Gauthier p. The problem here is as follows: if you want the money, you should form the intention to drink the toxin. However, you now know that if you are to form the intention and receive the money at midnight, come 8 a. So can you form the intention to drink the toxin now, on expected utility reasoning? Bratman and Kavka both think not, Gauthier thinks so. Similar cases of expected utility being self-defeating occur everywhere in cases of individual and social rationality.
This case is also much like the Prisoner's Dilemma situation where I would do better if I could form the intention to be conditionally co-operative, although expected utility reasoning tells me I should be an unconditional defector, resulting in my having only 2 instead of 3 utils.
As the toxin puzzle is a version of Newcomb's problem, and Newcomb's problem is, in the view of most, an intra-personal case of the Prisoner's Dilemma, such questions are certainly of importance for anyone vexed by the il- logic of the Prisoner's Dilemma. Irvine's paper discusses Newcomb'sproblem, the Prisoner's Dilemma and related "paradoxes" of rationality. In sum, for those who are interested in the Prisoner's Dilemma because it produces results which seem counter-intuitive given our definition of maximising rationality, such philosophical exploration is hearty food-for-thought and may hopefully lead to further understanding and modelling of conditional cooperation.
An incidental criticism is that there is neither a subject nor a name index in the book. There also exist a few citation errors and missing pieces of text in footnotes, so perhaps a bit more editing was required. However, these are minor distractions in a volume that contributes so powerfully to combining formal modelling through pure mathematics and computer simulation with questions in moral philosophy and decision theory. Anyone concerned with the inter-relationships between these fields should read the essays in this book, and anyone concerned with either subfield simulation or decision theory as applied to moral philosophy should make sure that they know whether or not they can do without it.
Notes 1 Many of the essays in Bicchieri, Jeffrey and Skyrms also address learning and evolution as applied to norm emergence in ways similar to models in this volume. The EAME page contains a number of user-friendly on-line interactive simulators and related materials, including the simulators used in the essays in this volume by Danielson and Skyrms.
Consider an analogy. Let us calculate the point on the hyperbolic curve with the same reciprocal cooperation for each experimental point. This question is enormously complex. This extremely simple rule was submitted by Rapoport, the psychologist mentioned at the beginning of this section. His essay is an important contribution to the literature on genetic algorithms in simulation, improving upon Axelrod's paper with a similar purpose. The full text of this article hosted at iucr.
