Top actors, writers, and athletes have agents, who help them find good jobs, in exchange for a small part of their income. But having an agent is pretty rare – why don’t the rest of us have agents?

You might think its only worth paying an agent 5% of your income for jobs where wages vary by large factors, and that most people’s wages are pretty much set by their occupation, education, etc. Not true, however. Consider: workers in the same occupation, with the same observable experience, school, etc. can easily earn 30% more, or 30% less, just based on the industry they work in. For example, in the auto industry both janitors and truck drivers make twice the salary of janitors and truck drivers in the “eating and drinking place” industry.

Although real ‘clock measured’ time is passing at a constant rate, experience tells us that our subjective sense of the amount of time that has occurred, or the speed at which time is passing, can vary, leading to distortions in the passage of time. When we feel like less time has occurred than actually has, time feels like it has speeded up. When we feel like more has occurred than actually has, time feels like it has slowed down.

Despite being commonly experienced, the mechanisms behind distortions of the passage of time are underresearched and, as a result, poorly understood. Anecdotal accounts imply that our experience of time is influenced by our emotions and the activities we engage in: ‘time flies when you’re having fun’, but not when an car is hurtling towards you.

It is not only enjoyment and fear that affect how quickly time appears to be passing: other alterations in subjective consciousness have similar effects. The consumption of drugs and alcohol has long been known to warp time experiences. […]

Having experienced distortions in the passage of time whilst under the influence of drugs and alcohol, there is some concern amongst users about whether any effects could be permanent. Heavy drug and alcohol use can result in long-term neurological damage (Harper, 2009) and impaired cognitive function (Fisk & Montgomery, 2009), both of which may alter timing ability even when drug use has ceased. Chronic cocaine and amphetamine use reduces dopamine D2 receptor availability (Volkow et al., 2001), and, because animal studies have demonstrated that dopamine levels influence duration perception, it is possible that chronic users of cocaine or methamphetamine may show impaired timing even after drug use has stopped.

Arousal, the researchers contend, actually affects our perception of time. […]

The researchers presented 116 males with images from an online Victoria’s Secret catalog and gauged their response to receiving one of two fictitious Amazon.com promotions: a gift certificate available that day or one available three months from now. They asked the subjects the dollar value that would compensate for having to wait. Those exposed to sexually charged imagery (versus those in a control group exposed to nature images) were found to be more impatient and expressed that future discounts would have to be steeper to compensate for the time delay.

They might say that sex between people who are in love is special (maybe even sacred), but they also know sex is part of the partnership of getting through life together and has to be considered pragmatically as well. Even people in love do not have identical physical and emotional needs, with the result that sex takes different forms and means more or less on different occasions. […]

Part of the mythology of love promises that loving couples will always want and enjoy sex together, unproblematically, freely and loyally. But most people know that couples are multi-faceted partnerships, sex together being only one facet, and that those involved very often tire of sex with each other. Although skeptics say today’s high divorce rate shows the love-myth is a lie, others say the problem is that lovers aren’t able or willing to do the work necessary to stay together and survive personal, economic and professional changes. Some of this work may well be sexual. In some partnerships where the spark has gone, partners grant each other the freedom to have sex with others, or pay others to spice up their own sex lives (as a couple or separately). This can take the form of a polyamorous project, with open contracts; as swinging, where couples play with others together; as polygamy or temporary marriage; as cheating or betrayal; or as paying for sex. […]

Many people, not just professional sex workers, know that the work of sex can mean allowing the other to take an active role and assuming a passive one as well as taking the active role or switching back and forth. Sometimes people do what they already know they like, and sometimes they experiment. Sometimes people don’t know what they want, or want to be surprised, or to lose control.

For some critics, the possession of money by clients gives them absolute power over workers and therefore means that equality is impossible.

Single-Nostril Navigational Reliance in Pigeons

We recorded the flight tracks of pigeons with previous homing experience equipped with a GPS data logger and released from an unfamiliar location with the right or the left nostril occluded. The analysis of the tracks revealed that the flight path of the birds with the right nostril occluded was more tortuous than that of unmanipulated controls. Moreover, the pigeons smelling with the left nostril interrupted their journey significantly more frequently and displayed more exploratory activity than the control birds, e.g. during flights around a stopover site.

How Randomly Selected Legislators Can Improve Parliament Efficiency

Democracies would be better off if they chose some of their politicians at random. That’s the word, mathematically obtained, from the Catanians’ extension of their random research, using insights they gleaned from the much earlier stupidity work by Cipolla.

Parliamentary voting behavior echoes, in a surprisingly detailed mathematical sense. Cipolla had sketched this in the “Basic Laws of Human Stupidity.” Cipolla gave an insulting, yet possibly accurate, description of any human group: “human beings fall into four basic categories: the helpless, the intelligent, the bandit, and the stupid.” Pluchino, Rapisarda, Garofalo and their colleagues base their mathematical model partly on this fourfold distinction.

Self-citing is often frowned upon, being considered (and sometimes is) vanity, egotism or an attempt in self-advertising. However, everyone self-cite because sooner or later, everyone builds upon previous findings. “Given the cumulative nature of the production of new knowledge, self-citations constitute a natural part of the communication process.” (Costas et al., 2010).

The argument whether citation analysis should include self-citation has been going on since the early days of citation analysis and is still ongoing. Early citation studies tended to exclude self-citation, but today’s Journal Impact Factor (JIF) includes them. […]

We’ve seen that self-citation can pay off at the journal level, but what about individual authors? Fowler and Aksnes (2007) did another research on the Norwegian database, but this time it was author rather than publication oriented. The percentage of author self-citation was rather low – 11% – but every self-citation yield, on average, 3.65 citations from others in 10 years. Fowler and Aksnes concluded that “self-citation advertises  not  only  the  article  in  question,  but  the  authors  in  question.”

In general, the more different is the new environment from the old, the better it is to start over. Rigid things are fragile, in that they break when you try to bend them far.

This suggests that designed systems tend to get irreversibly fragile as they adapt to specific environments. When context changes greatly, it is usually easier to build new systems from “scratch,” than to un-adapt systems designed for other contexts. Software tends to “rot“, for example. […]

Today I’m focused on this being bad news for the feasibility of immortality, at least for human-like creatures. You see, our minds seem designed to adapt to the environment in which we grow up, via youthful plasticity transitioning to elderly rigidity. For example, we are great at learning languages when young, and terrible when old. We are similarly receptive when young to new ways to categorize and conceive of things, but once we have often used particular ways, we find it harder to understand and use alternatives.

The brains of most animals peak in functionality during their key reproductive years, and do worse both before and after. Short lived animals peak sooner than long lived animals. Some of the early rise is due to learning, and some of later decline is due to the decline of individual cells and connections. Some of this pattern may even be due to an explicit plan to turn up some dials on plasticity early on, and then turn down those dials later. But I think another important part of this rise and fall is due to a general robust tendency for adapted systems to slide from plasticity to rigidity.

Confucianism is not a conceptual monolith but rather has a variety of traditions, versions and forms including imperial, reform, elite, merchant-house, and mass Confucianism. Just as Confucianism is multidimensional, democracy is also multifaceted including liberal, developmental, social, deliberative, and republican conceptions of democracy.The relationships between democracy and Confucianism therefore must be multiple and complex.

Does infinity exist?

This is a surprisingly ancient question. It was Aristotle who first introduced a clear distinction to help make sense of it. He distinguished between two varieties of infinity. One of them he called a potential infinity: this is the type of infinity that characterises an unending Universe or an unending list, for example the natural numbers 1,2,3,4,5,…, which go on forever. These are lists or expanses that have no end or boundary: you can never reach the end of all numbers by listing them, or the end of an unending universe by travelling in a spaceship. Aristotle was quite happy about these potential infinities, he recognised that they existed and they didn’t create any great scandal in his way of thinking about the Universe.

Aristotle distinguished potential infinities from what he called actual infinities. These would be something you could measure, something local, for example the density of a solid, or the brightness of a light, or the temperature of an object, becoming infinite at a particular place or time. You would be able to encounter this infinity locally in the Universe. Aristotle banned actual infinities: he said they couldn’t exist. This was bound up with his other belief, that there couldn’t be a perfect vacuum in nature. If there could, he believed you would be able to push and accelerate an object to infinite speed because it would encounter no resistance. […]

But in the world of mathematics things changed towards the end of the 19th century when the mathematician Georg Cantor developed a more subtle way of defining mathematical infinities. Cantor recognised that there was a smallest type of infinity: the unending list of natural numbers 1,2,3,4,5, … . He called this a countable infinity. […] This idea had some funny consequences. For example, the list of all even numbers is also a countable infinity. Intuitively you might think there are only half as many even numbers as natural numbers because that would be true for a finite list. But when the list becomes unending that is no longer true.

Every sect of Buddhism maintains that it is a religion of compassion and nonviolence. Throughout its history, however, Buddhism has occasionally been embroiled in warfare and military campaigns. Zen Buddhism in particular has managed to find its way into various military arts. From its incorporation into the Shaolin Monastery and the impact on the Japanese samurai to its absorption into the curriculum of several martial arts, Zen and fighting have come to be seen as closely related. This is due to certain characteristics of its doctrine as well as its practice. In fact, fighting is not entirely absent from Zen texts and literature. There are stories and kōans which depict amputations, encounters between samurai, or some kind of confrontation. Fighting, in the sense of an inner struggle is also present. […]

The objective of this examination is to draw parallels between Zen meditation and martial arts training and explore the reasons why Zen’s core philosophical doctrine and meditative practice can be integrated seamlessly into the martial arts.

Smeesters published a different study in the Journal of Experimental Psychology suggesting that even manipulating colors such as blue and red can make us bend one way or another.

Except that apparently none of it is true. Last month, after being exposed by Uri Simonsohn at the University of Pennsylvania, Dr. Smeesters acknowledged manipulating his data, an admission that been the subject of fervent discussions in the scientific community. Dr. Smeesters has resigned from his position and his university has asked that the respective papers be retracted from the journals. The whole affair might be written off as one unfortunate case, except that, as Smeesters himself pointed out in his defense in Discover Magazine, the academic atmosphere in the social sciences, and particularly in psychology, effectively encourages such data manipulation to produce “statistically significant” outcomes.

Back in October 2008, just after the investment bank Lehman Brothers collapsed, the International Monetary Fund unveiled its forecasts for growth in 2009. The IMF is the global lender to national governments; its economic pronouncements are highly respected. So what did it predict? The US would grow 0.1% in 2009, countries in the euro zone 0.2% and the world as a whole 2.6%. The actual outturns were declines of 3.5%, 4.2% and 2.6% respectively.

This lamentable short-sightedness was not unique. […]

To be fair to economists, there are two reasons why their forecasts are often likely to be wrong. The first is that humans are not inanimate objects; we change our behaviour and we watch the news. If every economist forecast a recession for 2013 and the predictions were widely publicised, businesses would cancel their investment programmes and consumers would start saving, not spending, for fear of losing their jobs. The recession would occur now, not next year.

Second, the economy is a complex mechanism with many working parts. Economists cannot run real-time experiments in the same way as scientists; operating one version of the economy with high interest rates and another with low rates, as a pharmacologist can offer one patient a new drug and another a placebo. There is no way of isolating the various factors that affect growth.

But there are more fundamental questions about the nature of the subject beyond the failure of economists to make accurate forecasts.

My theory, when it comes to buying lottery tickets, is that if you have disposable income to spare, then often the dreams and fantasies that accompany your lottery ticket purchase are in and of themselves worth $1. This is true not because dreams and fantasies are wonderful amazing and valuable things, although they can be; it’s more true because $1 is a very small amount of money. All too many people spend a significant percentage of their disposable income on lottery tickets, and that is a tragedy.

Now Ian Bogost has come along with a similar theory, relating to Kickstarter. Funding projects on Kickstarter is in itself “another form of entertainment.”

They walked to Ringsend, on the south bank of the Liffey, where (and here we can drop the Dante analogy) she put her hand inside his trousers and masturbated him. It was June 16, 1904, the day on which Joyce set “Ulysses.” When people celebrate Bloomsday, that is what they are celebrating. […]

Joyce had known only prostitutes and proper middle-class girls. Nora was something new, an ordinary woman who treated him as an ordinary man. The moral simplicity of what happened between them seems to have stunned him. It was elemental, a gratuitous act of loving that had not involved flattery or deceit, and that was unaccompanied by shame or guilt. That simplicity became the basis of their relationship.

You’re imagining, in the course of a game of make-believe, that you’re a cat. You don’t believe that you’re a cat. You are moved to say “Meow.” This case illustrates something that a theory of imagination should explain: sometimes when you imagine something, you are moved to act.

Consider another case. You’re watching a movie. A monster is on the loose and you are imagining, along with the movie, that it is at- tacking people willy-nilly. You do not believe there is a monster on the loose or that you are in any danger, but still you feel afraid. This case illustrates something else that a theory of imagination should explain: sometimes we have emotional reactions to things that we do not believe but merely imagine.

[…]

To be clearer, the first phenomenon we think needs accounting for is that sometimes you are moved to act by something you imagine but do not believe. Children are a good source of examples of this phe- nomenon — they act on the basis of their imaginings a lot. […]

Other, related questions that we try to answer are: How do imaginings motivate behavior? To what extent, and in what respects, is the behavior-generating role of imagination like the behavior-generating role of belief? Beliefs don’t generate behavior all on their own; they do so in combination with desires. If imaginings play something like the role of beliefs in generating behavior, is there also some state that plays something like the role of desire? If so, what kind of state is it — a desire, or something else? And if it’s a desire, a desire about what?

One of the worst parts of being pregnant […] is what is commonly referred to as morning sickness.

This term for the nausea and vomiting accompanying pregnancy is something of a misnomer, actually, since such gastrointestinal issues certainly aren’t limited to the morning hours. Rather, for those women who do get green around the gills (and not all do; more on that later) sudden bouts of toilet-hugging can happen morning, noon and night. […]

Why, if it is indeed an evolutionary adaptation, does pregnancy sickness not occur in all (or at least, almost all) pregnant women? […]

So what does Gallup say is the real culprit behind nausea and vomiting in early pregnancy? Semen. More specifically, unfamiliar semen.

Gallup’s evolutionary reinterpretation of pregnancy sickness is quite new—so new, in fact, that it hasn’t been put to a test. But at the 2012 meeting of the Northeastern Evolutionary Psychology Society in Plymouth, N.H., he and graduate student Jeremy Atkinson laid out a set of explicit predictions that, if borne out by data, would support their model and may lead scholarship away from the traditional embryo-protection account.

First, the authors predict that the intensity of pregnancy sickness should be directly proportional to the frequency of insemination by the child’s father. “Risk factors for morning sickness,” they reason, “should include condom use, infrequent insemination, and not being in a committed relationship.” In fact, Gallup and Atkinson believe that lesbians with little (if any) previous exposure to semen who are impregnated by artificial insemination should have some of the worst cases of nausea and vomiting. Also, pregnancy sickness should wane in severity from one consecutive pregnancy to the next, but only assuming that the same man sires each successive offspring. By contrast, a change in paternity between offspring should reinstate pregnancy sickness.

1. Always and inevitably, everyone underestimates the number of stupid individuals in circulation.

2. The probability that a certain person be stupid is independent of any other characteristic of that person.

3. A stupid person is a person who causes losses to another person or to a group of persons, while himself deriving no gain and even possibly incurring losses.

4. Non-stupid people always underestimate the damaging power of stupid individuals. In particular, non-stupid people constantly forget that at all times and places and under any circumstances to deal and/or associate with stupid people always turns out to be a costly mistake.

In the West, plot is commonly thought to revolve around conflict: a confrontation between two or more elements, in which one ultimately dominates the other. The standard three- and five-act plot structures—which permeate Western media—have conflict written into their very foundations. A “problem” appears near the end of the first act; and, in the second act, the conflict generated by this problem takes center stage. Conflict is used to create reader involvement even by many post-modern writers, whose work otherwise defies traditional structure.

The necessity of conflict is preached as a kind of dogma by contemporary writers’ workshops and Internet “guides” to writing. A plot without conflict is considered dull; some even go so far as to call it impossible. This has influenced not only fiction, but writing in general—arguably even philosophy. Yet, is there any truth to this belief? […]

For countless centuries, Chinese and Japanese writers have used a plot structure that does not have conflict “built in,” so to speak. Rather, it relies on exposition and contrast to generate interest. This structure is known as kishōtenketsu.

Kishōtenketsu contains four acts: introduction, development, twist and reconciliation.
