A good rule of thumb might be, “If I added a zero to this number, would the sentence containing it mean something different to me?” If the answer is “no,” maybe the number has no business being in the sentence in the first place.

A skilled professional I know had to turn down an important freelance assignment because of a recurring commitment to chauffeur her son to a resumé-building “social action” assignment required by his high school. This involved driving the boy for 45 minutes to a community center, cooling her heels while he sorted used clothing for charity, and driving him back—forgoing income which, judiciously donated, could have fed, clothed, and inoculated an African village. The dubious “lessons” of this forced labor as an overqualified ragpicker are that children are entitled to treat their mothers’ time as worth nothing, that you can make the world a better place by destroying economic value, and that the moral worth of an action should be measured by the conspicuousness of the sacrifice rather than the gain to the beneficiary.

I’m always fascinated by the number of people who proudly build columns, tweets, blog posts or Facebook posts around the same core statement: “I don’t understand how anyone could (oppose legal abortion/support a carbon tax/sympathize with the Palestinians over the Israelis/want to privatize Social Security/insert your pet issue here)." It’s such an interesting statement, because it has three layers of meaning.

The first layer is the literal meaning of the words: I lack the knowledge and understanding to figure this out. But the second, intended meaning is the opposite: I am such a superior moral being that I cannot even imagine the cognitive errors or moral turpitude that could lead someone to such obviously wrong conclusions. And yet, the third, true meaning is actually more like the first: I lack the empathy, moral imagination or analytical skills to attempt even a basic understanding of the people who disagree with me.

In short, “I’m stupid.” Something that few people would ever post so starkly on their Facebook feeds.

Your younger nerd takes offense quickly when someone near him begins to utter declarative sentences, because he reads into it an assertion that he, the nerd, does not already know the information being imparted. But your older nerd has more self-confidence, and besides, understands that frequently people need to think out loud. And highly advanced nerds will furthermore understand that uttering declarative sentences whose contents are already known to all present is part of the social process of making conversation and therefore should not be construed as aggression under any circumstances.

How to compose a successful critical commentary:

1. You should attempt to re-express your target’s position so clearly, vividly, and fairly that your target says, “Thanks, I wish I’d thought of putting it that way.

2. You should list any points of agreement (especially if they are not matters of general or widespread agreement).

3. You should mention anything you have learned from your target.

4. Only then are you permitted to say so much as a word of rebuttal or criticism.

D.C. Dennett, Intuition Pumps and Other Tools for Thinking. Dennett himself is summarising Anatol Rapoport.

A shipowner was about to send to sea an emigrant-ship. He know that she was old, and not over-well built at the first; that she had seen many seas and climes, and often had needed repairs. Doubts had been suggested to him that possibly she was not seaworthy. These doubts preyed upon his mind and made him unhappy; he thought that perhaps he ought to have her thoroughly overhauled and refitted, even though this should put him to great expense. Before the ship sailed, however, he succeeded in overcoming these melancholy reflections. He said to himself that she had gone safely though so many voyages and weathered so many storms, that it was idle to suppose she would not come safely home from this trip also. He would put his trust in Providence, which could hardly fail to protect all these unhappy families that were leaving their fatherland to seek for better times elsewhere. He would dismiss from his mind all ungenerous suspicions about the honesty of builders and contractors. In such a way he acquired a sincere and comfortable conviction that his vessel was thoroughly safe and seaworthy; he watched her depature with a light heart, and benevolent wishes for the success of the exiles in...

Alex Jordan, a grad student at Stanford, came up with the idea of asking people to make moral judgments while he secretly tripped their disgust alarms. He stood at a pedestrian intersection on the Stanford campus and asked passersby to fill out a short survey. It asked people to make judgments about four controversial issues, such as marriage between first cousins, or a film studio’s decision to release a documentary with a director who had tricked some people into being interviewed. Alex stood right next to a trash can he had emptied. Before he recruited each subject, he put a new plastic liner into the metal can. Before half of the people walked up (and before they could see him), he sprayed the fart spray twice into the bag, which “perfumed” the whole intersection for a few minutes. Before other recruitments, he left the empty bag unsprayed. Sure enough, people made harsher judgments when they were breathing in foul air

I wonder if anyone who needs to make important judgments a lot makes an actual effort to maintain affective hygiene. It seems like a really good idea, but poor signalling.

A Verb Called Self
I am the playing, but not the pause.
I am the effect, but not the cause.
I am the living, but not the cells.
I am the ringing, but not the bells.
I am the animal, but not the meat.
I am the walking, but not the feet.
I am the pattern, but not the clothes.
I am the smelling, but not the rose.
I am the waves, but not the sea
Whatever my substrate, my me is still me.
I am the sparks in the dark that exist as a dream -
I am the process, but not the machine.

A conversation between me and my 7-year-old cousin:

Her: "do you believe in God?"

Me: "I don't, do you?"

Her: "I used to but, then I never really saw any proof, like miracles or good people getting saved from mean people and stuff. But I do believe in the Tooth Fairy, because ever time I put a tooth under my pillow, I get money out in the morning."

"I mean, my lord Salvara, that your own expectations have been used against you. You have a keen sense for men of business, surely. You've grown your family fortune several times over in your brief time handling it. Therefore, a man who wished to snare you in some scheme could do nothing wiser than to act the consummate man of business. To deliberately manifest all your expectations. To show you exactly what you expected and desired to see."

"It seems to me that if I accept your argument," the don said slowly, "then the self-evident truth of any legitimate thing could be taken as grounds for its falseness. I say Lukas Fehrwight is a merchant of Emberlain because he shows the signs of being so; you say those same signs are what prove him counterfeit. I need more sensible evidence than this."

It seems to me that educated people should know something about the 13-billion-year prehistory of our species and the basic laws governing the physical and living world, including our bodies and brains. They should grasp the timeline of human history from the dawn of agriculture to the present. They should be exposed to the diversity of human cultures, and the major systems of belief and value with which they have made sense of their lives. They should know about the formative events in human history, including the blunders we can hope not to repeat. They should understand the principles behind democratic governance and the rule of law. They should know how to appreciate works of fiction and art as sources of aesthetic pleasure and as impetuses to reflect on the human condition.

On top of this knowledge, a liberal education should make certain habits of rationality second nature. Educated people should be able to express complex ideas in clear writing and speech. They should appreciate that objective knowledge is a precious commodity, and know how to distinguish vetted fact from superstition, rumor, and unexamined conventional wisdom. They should know how to reason logically and s

Yet none of these sights [of the Scottish Highlands] had power, till a recent period, to attract a single poet or painter from more opulent and more tranquil regions. Indeed, law and police, trade and industry, have done far more than people of romantic dispositions will readily admit, to develope in our minds a sense of the wilder beauties of nature. A traveller must be freed from all apprehension of being murdered or starved before he can be charmed by the bold outlines and rich tints of the hills. He is not likely to be thrown into ecstasies by the abruptness of a precipice from which he is in imminent danger of falling two thousand feet perpendicular; by the boiling waves of a torrent which suddenly whirls away his baggage and forces him to run for his life; by the gloomy grandeur of a pass where he finds a corpse which marauders have just stripped and mangled; or by the screams of those eagles whose next meal may probably be on his own eyes.

I feel it myself, the glitter of nuclear weapons. It is irresistible if you come to them as a scientist. To feel it’s there in your hands. To release the energy that fuels the stars. To let it do your bidding. And to perform these miracles, to lift a million tons of rock into the sky, it is something that gives people an illusion of illimitable power, and it is in some ways responsible for all our troubles... this is what you might call ‘technical arrogance’ that overcomes people when they see what they can do with their minds.

In a study recently published in the journal PloS One, our two research teams, working independently, discovered that when people are presented with the trolley problem in a foreign language, they are more willing to sacrifice one person to save five than when they are presented with the dilemma in their native tongue.

One research team, working in Barcelona, recruited native Spanish speakers studying English (and vice versa) and randomly assigned them to read this dilemma in either English or Spanish. In their native tongue, only 18 percent said they woul

Dreams demonstrate that our brains (and even rat brains) are capable of creating complex, immersive, fully convincing simulations. Waking life is also a kind of dream. Our consciousness exists, and is shown particular aspects of reality. We see what we see for adaptive reasons, not because it is the truth. Nerds are the ones who notice that something is off - and want to see what's really going on.

A lot of people believe fruit juices to be healthy. They must be… because they come from fruit, right? But a lot of the fruit juice you find in the supermarket isn’t really fruit juice. Sometimes there isn’t even any actual fruit in there, just chemicals that taste like fruit. What you’re drinking is basically just fruit-flavored sugar water. That being said, even if you’re drinking 100% quality fruit juice, it is still a bad idea. Fruit juice is like fruit, except with all the good stuff (like the fiber) taken out… the main thing left of the actual

One of the key concepts in Common Law is that of the reasonable man. Re-reading A.P. Herbert, it struck me how his famously insulting description of the reasonable man bears a deep resemblance to that of the ideal rationalist:

It is impossible to travel anywhere or to travel for long in that confusing forest of learned judgments which constitutes the Common Law of England without encountering the Reasonable Man. He is at every turn, an ever-present help in time of trouble, and his apparitions mark the road to equity and right. There has never been a probl

You know how people are always telling you that history is actually really interesting if you don’t worry about trivia like dates? Well, that’s not history, that’s just propaganda. History is dates. If you don’t know the date when something happened, you can’t provide the single most obvious reality check on your theory of causation: if you claim that X caused Y, the minimum you need to know is that X came before Y, not afterwards.

In 2014, marriage is still the best economic arrangement for raising a family, but in most other senses it is like adding shit mustard to a shit sandwich.
