In 1977, Roman Polanski drugged, raped, and sodomized a 13-year-old girl. When he believed a sort-of-plea-bargain was about to come unstuck, he took it on the lam. He lived the high life in this self-imposed exile for thirty years, until busted in Switzerland recently. Now various of the usual suspects on the right wing’s enemies list are campaigning to block his extradition.
There’s a good deal of perplexity being expressed about this, and some predictable chuntering from right-wingers about lefties being moral degenerates. But this flap isn’t really about politics at all — it’s much simpler than that. It’s about people who think of themselves as “artistes” reserving themselves a get-out-of-jail card when they feel like behaving like repellent scum of the earth, too.
[…]
If you want to make that argument, Roman Polanski makes a great stake in the ground — not in spite of the heinousness of his crime, but because of it. If even a child-raper can invoke the all-purpose artiste excuse for scumminess, than the merely ordinary transgressions of artistes become trivia to be airily dismissed. And if the Polanski case becomes a “teachable moment” whereby people can be talked into feeling like boors or philistines for even thinking that artistes should be held to civilized standards of behavior, so much the better!
None of this is more than tenuously connected to leftism, and I have to say the the right-wing efforts to gin up indignation on that score sound quite contrived and stupid to me. This dispute isn’t about politics, it’s about privilege — not just whether Roman Polanski is above the law, but about whether his defenders can claim to be too.

QotD: Banishing racism
The simple, powerful truth that banishes racist prejudice is this: the individual is not the mass. Statistical distributions do not predict the traits of individuals. It’s OK to acknowledge that (for example) Ashkenazic Jews average significantly brighter than gentile whites, because the difference in the means of those bell curves tells us nothing about where any single Jew or gentile falls on them.
We can – we must, in fact – learn to judge individuals as individuals, not as members of racial or other ascriptive groups. This has always been the right thing to do; as knowledge about genetic group differences becomes more detailed and widespread, we will need to learn how to focus rigorously on individuals with the same discipline (and the same justified fear of failure) that we now apply to averting our eyes from genetic group differences.
Part of the reason this evolution won’t be easy is that so much of our politics has been distorted by racial grievance-mongering. It’s not only the obvious bad guys like neo-Nazis, Black separatists like Louis Farrakhan, and Bharatiya Janata who are invested in racialist categorization as a lever to power. The political Left has fallen into a lazy habit of screaming “racist!” at anyone who disagrees with them, won’t readily relinquish that rhetorical club, and have a lot invested in the present system of taboo, resentment, “disparate impact” legislation, and racial identity politics; expect them, too, to be part of the problem rather than part of the solution.
Still, the right strategy is clear. Actual knowledge makes both prejudice and repression unsustainable. “Know thyself!” said the oracle, and behavioral genetics will allow – actually, force us – to know ourselves in ways we never have before. That way lies the pain of revelation, but also the path of redemption.

QotD: Open-source the data
We know, from experience with software, that secrecy is the enemy of quality — that software bugs, like cockroaches, shun light and flourish in darkness. So, too, with mistakes in the interpretation of scientific data; neither deliberate fraud nor inadvertent error can long survive the skeptical scrutiny of millions. The same remedy we have found in the open-source community applies – unsurprisingly, since we learned it from science in the first place. Abolish the secrecy, let in the sunlight.

QotD: Collective-action problems – perfect state response versus flawed private responses
Our key insight is a pessimistic one: this is the sort of situation which, though individuals and markets don’t handle it well, isn’t actually handled well by governments either. The fundamental mistake of statist thinking is to juxtapose the tragically, inevitably flawed response of individuals and markets to large collective-action problems like this one against the hypothetical perfection of idealized government action, without coping with the reality that government action is also tragically and inevitably flawed.
The implicit burden of the article, after all, is indignation that the government has been done too little and the wrong things. What the author fails to grasp (because his thinking is warped by the religion of state-worship) is that this sort of dysfunction is not a sporadic accidental failure that could be corrected by sufficiently virtuous thoughts and deeds; it is an essential failure, entirely predictable from the incentives operating on all the actors (including the actors within government).
His sort of fantasy thinking implicitly throws a burden of proof on anarchists to construct a perfect response to something like the Deepwater Horizon disaster in a stateless system, or else have their critique of statism dismissed as heartless and inadequate. But the correct analysis is to notice that we can only do what we can only do, and compare the rationally expectable effectiveness of flawed government action against the rationally expectable effectiveness of flawed individual and market action.
The second level of error, once you get this far, is to require that the market action achieve a better outcome without including all the continuing, institutional costs of state action in the accounting. So, for example, other parts of the continuing costs of accepting state action to solve this individual toxic-exposure problem in the Deep Horizon aftermath is that Americans will be robbed every April 15th of five in twelve parts of their income (on average), and be randomly killed in no-knock drug raids. And it’s no use protesting that these abuses are separable from the “good” parts of government as long as you’re also insisting that the prospect of market failures is not separable from the good behavior of markets!
Irrational anarchists believe that utopia is somehow achievable in a stateless system; they make the exact reciprocal error from statists, believing that all evil proceeds from government. Rational anarchists like myself know that stateless systems will have tragic failures too, but believe after analysis that they would have fewer and smaller ones.
If this seems doubtful to you, do not forget to include all the great genocides of the 20th century in the cost of statism. It was contemplating those that turned me into an anarchist – because that sort of eruption of fire and blood, too, is not accidental but essential given the logic of state collectivism.

QotD: Sexual equality and the risk of demographic collapse
I like living in a society where women are, generally speaking, as free to choose their own path in life as I am. I like strong women, women who are confident and look me in the eye and see themselves as my equals. But I wonder, sometimes, if sexual equality isn’t doomed by biology. The relevant facts are (a) men and women have different optimal reproductive strategies because of the asymmetry in energy investment – being pregnant and giving birth is a lot more costly and risky than ejaculating, and (b) a woman’s fertile period is a relatively short portion of her lifetime. Following the logic out, it may be that the consequence of sexual equality is demographic collapse — nasty cultures which treat women like brood mares are the future simply because the nice cultures that don’t do that stop breeding at replacement rates.

QotD: Repressing the facts in genetic research
Now, in 2010, cleared-eyed observers are imagining a near-term future scenario that looks like this: (1) we will shortly have genomic-sequence information on hundreds of thousands of human beings from all over the planet, enough to build a detailed map of human genetic variation and a science of behavioral genetics. (2) We will confirm that variant alleles correlate strongly with significant measures of human ability and character, beginning with IQ and quite possibly continuing to distribution of time preference, sociability, docility, and other important traits. (3) We will discover that these same alleles correlate significantly with traditional indicia of race.
In fact, given the state of our present knowledge, I judge all three of these outcomes are near certain. I have previously written about some of the evidence in Racism and Group Differences. The truth is out there; well known to psychometricians, population geneticists and anyone who cares to look, but surrounded by layers of denial. The cant has become thick enough to, for example, create an entire secondary mythology about IQ (e.g., that it’s a meaningless number or the tests for it are racially/culturally biased). It also damages our politics; many people, for example, avert their eyes from the danger posed by Islamism because they fear being tagged as racists. All this repression has been firmly held in place by the justified fear of truly hideous evils – from the color bar through compulsory sterilization of the “inferior” clear up to the smoking chimneys at Treblinka and Dachau. But … if the repressed is about to inevitably return on us, how do we cope?
It’s not going to be easy. I saw this coming in the mid-1990s, and I’m expecting the readjustment to be among the most traumatic issues in 21st-century politics. The problem with repression, on both individual and cultural levels, is that when it breaks down it tends to produce explosions of poorly-controlled emotional energy; the release products are frequently ugly. It takes little imagination to visualize a future 15 or 20 years hence in which the results of behavioral genetics are seized on as effective propaganda by neo-Nazis and other racist demagogues, with the authority of science being bent towards truly appalling consequences.

QotD: Buying “organic” food
… every time I buy “organic”, I feel like I’m sending a reinforcement to several different forms of vicious stupidity, beginning with the term “organic” itself. Duh! Actually, all food is “organic”; the term just means “chemistry based on carbon chains”.
Take “no GMOs” for starters. That’s nonsense; it’s barely even possible. Humans have been genetically modifying since the invention of stockbreeding and agriculture; it’s what we do, and hatred of the accelerated version done in a genomics lab is pure Luddism. It’s vicious nonsense, too; poor third-worlders have already starved because their governments refused food aid that might contain GMOs. And without GMOs it’s more than possible that the new wave of wheat rust, once it really gets going, might condemn billions to death.
Vegan? I’ve long since had it up to here with the tissue of ignorance and sanctimony that is evangelical veganism. Comparing our dentition and digestive tracts with those of cows, chimps, gorillas, and bears tells the story: humans are designed to be unspecialized omnivores, and the whole notion that vegetarianism is “natural” is so much piffle. It’s not even possible except at the near end of 4000 years of GMOing staple crops for higher calorie density, and even now you can’t be a vegan in a really cold climate (like, say, Tibet) because it’ll kill you. In warmer ones, you better be taking carnitine and half a dozen vitamins or you’re going to have micronutrient issues sneak up on you over a period of years.
OK, I give on gluten-free. Some people do have celiac disease; that’s a real need. But “no trans fat”? Pure faddery, or the next thing to it. The evidence indicting trans fats is extremely slim and surrounded by a cloud of food-nannyist hype. I hate helping to keep that sort of balloon inflated with my dollars.
Who could be against “fair trade”? Well, me … because the “fair trade” crowd pressures individual growers to join collectives with “managed” pricing. If you’re betting that this means lazy but politically adept growers with poor resource management and productivity prosper at the expense of more efficient and harder-working ones, you’ve broken the code.
Finally, “pesticide-free”. Do I like toxic chemicals on my food? No … but I also don’t fool myself about what happens when you don’t use them. This ties straight back to the general cluster of issues around factory farming. Without the productivity advantages of pesticides, synthetic fertilizer, and other non-“organic” methods, farm productivity would plummet. Relatively wealthy people like me would cope with reduced availability by paying higher prices, but huge numbers of the world’s poor would starve.
I buy “organic” food because it tastes better and I can, but I feel guilty about reinforcing all the kinds of delusion and superstition and viciousness that are tied up in that label. We simply cannot feed a world population of 6.6 billion without pesticides and factory farming and GMOs and preservatives in most bread; now, and probably forever, “organic” food will remain a luxury good.
Try telling its political partisans that, though. Hyped on their belief in their own virtue, and blissfully ignorant about scale problems, they have already engineered policies that have cost thousands of lives during spot famines. The potential death toll from (especially) anti-GMO policies is three orders of magnitude higher.
And my problem reduces to this: how can I buy the kind of food I want without supporting dangerous delusions?

QotD: The sting in the tail of genetic research
A specter is haunting genetics; the shadow of racialist slavery, eugenics, and Naziism. Western civilization since 1945, traumatized by the horror of the Holocaust, has elevated anti-racism into an unquestionable secular piety. Much good has been accomplished thereby, but like all pieties the worthy results have been accompanied by a great deal of willed repression, denial, and cant. Evidence that racial genetic differences do matter is not actually hard to find; Murray & Herrnstein’s The Bell Curve (1994) included a brave and excellent summation of the science on this point. Consequently, the bien-pensant reaction to that book was hysterical vilification, anathematization of heresy in full cry. Even at the time the lurking fear beneath the hysteria was easy to spot – that the authors might, after all, be right, and must be damned even more intensely because they might be.

QotD: The foundational weirdness of Judeo/Christian/Islamic religions
One of my regular commenters asked, in a previous thread, “If everyone was truly released from the shackles of religion, and got beyond the false moral codes imposed on them, would society collapse in a heap of nihilism?” This question needs a longer answer than will fit in a reply comment.
The shortest summary is “No!” The less short answer is: “No, because religious moral codes are epiphenomenal.” And it is on point to add that the question reveals serious ignorance of the actual traits of most religions over most of history.
I’ll address the historical point first. The commenter’s question was framed from within the assumptions of one particular family of religions: the Judeo/Christian/Islamic tradition, which are more succinctly describable as the bastard offspring of Zoroastrian dualism. In this family, “religion” bundles cosmology, theology, and morality into a single total system designed primarily to enforce norms by programming the believer with an internalized guilt machine.
Because the dominant religions of the modern West are all derived from this group, it is difficult for Westerners to understand how bizarre and exceptional these religions are in a broader context. Most religions are not total systems. Most religions do not tie morality to cosmology. In fact, most religions have very little to say about morality at all!
Consider, for example, an Altaic shaman. It’s not his job to pronounce on who should sleep with who, or to tell people that theft is wrong. It’s not even his job to tell people that they must worship Tengri or Kara-han; dealing with the gods is his specialty, thank you. His job combines aspects of psychologist and medic with a bit of divination. The closest analog of “morality”, in his culture, is a set of inherited customs and taboos which is reinforced by explanatory myths but not generated by them and not really dependent on them. The closest equivalent of religious structures about right and wrong is an elaborate set of rules about ritual purity and impurity. In the jargon of the field, his religion is an orthopraxy rather than an orthodoxy.
Over most human cultures in most human history, “religion” has been much more like Altaic shamanism than like Christianity, Judaism, or Islam. Er, so why didn’t these cultures “collapse in a heap of nihilism”? The same question actually applies to modern religions outside the post-Zoroastrian family. Buddhism and Hinduism, for example, are almost completely unconcerned with “morality”. Hinduism is organized around ritual purity and impurity; Buddhism’s quest for merit is about liberation of the self from attachments, not about duties one owes to God or others.

QotD: Ego and the A-listers
It’s not that people at the top of their fields are more virtuous. Well … actually I think people at the top of their fields do tend to be more virtuous, for the same reason they tend to be be more intelligent, less neurotic, longer-lived, better-looking, and physically healthier than the B-listers and below. Human capability does not come in [neatly] divisible chunks; almost every individual way that humans can excel is tangled up with other ways at a purely physiological level, with immune-system capability lurking behind a surprisingly large chunk of the surface measures. But I don’t think the mean difference in “virtue”, however you think that can actually be defined, explains what I’m pointing at.
No. It’s more that ego games have a diminishing return. The farther you are up the ability and achievement bell curve, the less psychological gain you get from asserting or demonstrating your superiority over the merely average, and the more prone you are to welcome discovering new peers because there are so damn few of them that it gets lonely. There comes a point past which winning more ego contests becomes so pointless that even the most ambitious, suspicious, external-validation-fixated strivers tend to notice that it’s no fun any more and stop.
[…]
I think there are a couple of different reasons people tend to falsely attribute pathological, oversensitive egos to A-listers. Each reason is in its own way worth taking a look at.
The first and most obvious reason is projection. “Wow, if I were as talented as Terry Pratchett, I know I’d have a huge ego about it, so I guess he must.” Heh. Trust me on this; he doesn’t. This kind of thinking reveals a a lot about somebody’s ego and insecurity, alright, but not Terry’s.
There’s a flip side to projection that I think of as the “Asimov game”. I met Isaac Asimov just a few months before he died. Isaac had long been notorious for broadly egotistical behavior and a kind of cheerful bombast that got up a lot of peoples’ noses. But if you ever met him, and you were at all perceptive, you might see that it was all a sort of joke. Isaac was laughing inside at everyone who took his “egotism” seriously – and, at the same time, watching hungrily for people who could see through the self-parody, because they might – might – actually be among the vanishingly tiny minority that constituted his actual peers. The Asimov game is a constant temptation to extroverted A-listers; I’ve been known to fall into it myself. It’s not really anybody’s fault that a lot of people are fooled by it.
Another confusing fact is that though A-listers may not be about ego or status competition, they will often play such games ruthlessly and effectively when that gets them something they actually want. The something might be more money from a gig, or a night in the hay with an attractive wench, or whatever; the point is, if you catch an A-lister in that mode, you might well mistake for egotism some kinds of display behavior that actually serve much more immediate and instrumental purposes. Your typical A-lister in that situation (and this includes me, now) is blithely unconcerned that a bystander might think he’s egotistical; the money or the wench or the whatever is the goal, not the approval or disapproval of bystanders.
Finally, a lot of people confuse arrogance with ego. A-listers (and I am including myself, again, this time) are, as a rule, colossally arrogant. That is, they have utter confidence in their ability to meet challenges that would humble or break most people. Do not be fooled by the self-deprecating manner that many A-listers cultivate; it is a mask adopted for social purposes, mostly to avoid freaking out the normal monkeys. But this arrogance is not the same as egotism; in fact, in many ways it is the opposite. It is possible to be arrogant about one’s abilities compared to the statistically average human being and the range of challenges one is likely to encounter, but deeply and genuinely humble when dealing with peers or contemplating the vastness of one’s own ignorance and incapability relative to what one could imagine being. In fact, this combination of attitudes is completely typical of the A-listers I have known.

QotD: Airbrushing out the worst parts of “Lost Cause” mythology
The South could have become a running sore, a cauldron of low-level insurrection and guerilla warfare that blighted the next century of U.S. history. Instead, it is now the most patriotic region of the U.S. – as measured, for example, by regional origins of U.S. military personnel. How did this happen?
Looking back, we can see that between 1865 and around 1914 the Union and the former South negotiated an imperfect but workable peace. The first step in that negotiation took place at Appomattox, when the Union troops accepting General Robert E. Lee’s surrender saluted the defeated and allowed them to retain their arms, treating them with the most punctilious military courtesy due to honorable foes.
Over the next few years, the Union Army reintegrated the Confederate military into itself. Confederate officers not charged with war crimes were generally able to retain rank and seniority; many served in the frontier wars of the next 35 years. Elements of Confederate uniform were adopted for Western service.
The political leaders of the revolt were not executed. Instead, they were spared to urge reconciliation, and generally did. By all historical precedent they were treated with shocking leniency. This paid off.
Of course, not all went smoothly. The Reconstruction of the South between 1863 and 1877 was badly bungled, creating resentments that linger to this day and – in the folk memory of Southerners – often overshadow the harms of the war itself. The condition of emancipated blacks remained dire.
But overall, the reintegration of the South went far better than it could have. Confederate nationalism was successfully reabsorbed into American nationalism. One of the prices of this adjustment was that Confederate heroes had to become American heroes. An early and continuing example of this was the reverence paid to Robert E. Lee by Unionists after the war; his qualities as a military leader were extolled and his opposition to full civil rights for black freedmen memory-holed.
Lee’s heroism and ascribed saintliness would layer become a central prop in “Lost Cause” romanticism, which portrayed the revolt as an honorable struggle for a Southern way of life while mostly airbrushing out – but sometimes, unforgiveably, defending – the institution of slavery. Even today, the “soft” airbrushing version of Lost Cause retains a significant hold on Southerners who would never dream of defending slavery.

QotD: The Smartphone, the Eater-of-Gadgets
I’ve been thinking for some time now that the smartphone has achieved a kind of singularity, becoming a black hole that sucks all portable electronics into itself. PDAs – absorbed. Music players – consumed. Handset GPSes – eaten. Travel-alarm clocks, not to mention ordinary watches – subsumed. Calculators – history. E-readers under serious pressure, and surviving only because e-paper displays have lower battery drain and are a bit larger. Compasses – munched. Pocket flashlights – crunched. Fobs for keyless locks – being scarfed down as we speak, though not gone yet.
[…]
But in an entertaining inversion, one device of the future actually works on smartphones now. Because I thought it would be funny, I searched for “tricorder” in the Android market. For those of you who have been living in a hole since 1965, a tricorder is a fictional gadget from the Star Trek universe, an all-purpose sensor package carried by planetary survey parties. I expected a geek joke, a fancy mock-up with mildly impressive visuals and no actual function. I was utterly gobsmacked to discover instead that I had an arguably real tricorder in my hand.
Consider. My Nexus One includes a GPS, an accelerometer, a microphone, and a magnetometer. That is, sensors for location, magnetic field, gravitational fields, and acoustic energy. Hook a bit of visualization and spectral analysis to these sensors, and bugger me with a chainsaw if you don’t have a tricorder. A quad- or quintcorder, actually.
And these sensors are already completely stock on smartphones because sensor electronics is like any other kind; amortized over a large enough production run, their incremental cost approaches epsilon because most of their content is actually design information (cue the shade of Bucky Fuller talking about ephemeralization). Which in turn points at the fundamental reason the smartphone is Eater-of-Gadgets; because, as the tricorder app deftly illustrates, the sum of a computer and a bunch of sensors costing epsilon is so synergistically powerful that it can emulate not just real single-purpose gadgets but gadgets that previously existed only as science fiction!
[…]
I specified “personal” radios because radios have something in common with personal computers; their main design constraints are actually constraints on a peripheral stage. For a computer you’ll be using for hours at a time you really want a full-sized hard keyboard and a display bigger than a smartphone’s; for a really good radio, the kind you supply sound for a party with, you need speakers with resonant cavities that won’t fit in a smartphone enclosure.
Digital cameras are another diagnostic case. The low-end camera with small lenses is already looking like a goner; the survivors will be DSLRs and more generally those with precision optics too large and too expensive to fit in a phone case.
These two examples suggest Raymond’s Rule of Smartphone Subsumption: if neither the physics nor the ergonomics of a gadget’s function require peripherals larger than will fit in a smartphone case, the smartphone will eat it!

QotD: Three lessons on weapons handling in moments of danger
Nothing most of us will ever do combines the moral weight of life-or-death choice with the concrete immediacy of the moment as thoroughly as the conscious handling of instruments deliberately designed to kill. As such, there are lessons both merciless and priceless to be learned from bearing arms — lessons which are not merely instructive to the intellect but transformative of one’s whole emotional, reflexive, and moral character.
The first and most important of these lessons is this: it all comes down to you.
No one’s finger is on the trigger but your own. All the talk-talk in your head, all the emotions in your heart, all the experiences of your past — these things may inform your choice, but they can’t move your finger. All the socialization and rationalization and justification in the world, all the approval or disapproval of your neighbors — none of these things can pull the trigger either. They can change how you feel about the choice, but only you can actually make the choice. Only you. Only here. Only now. Fire, or not?
A second is this: never count on being able to undo your choices.
If you shoot someone through the heart, dead is dead. You can’t take it back. There are no do-overs. Real choice is like that; you make it, you live with it — or die with it.
A third lesson is this: the universe doesn’t care about motives.
If your gun has an accidental discharge while pointed an unsafe direction, the bullet will kill just as dead as if you had been aiming the shot. “I didn’t mean to” may persuade others that you are less likely to repeat a behavior, but it won’t bring a corpse back to life.
These are hard lessons, but necessary ones. Stated, in print, they may seem trivial or obvious. But ethical maturity consists, in significant part, of knowing these things — not merely at the level of intellect but at the level of emotion, experience and reflex. And nothing teaches these things like repeated confrontation with life-or-death choices in grave knowledge of the consequences of failure.

“Evolved cognition is a kludge – more properly, multiple stacks of kludges – developed under selection to be just barely adequate at coping”
ESR considers the role of programmers who need to document their software, after a brief trip into the kludginess of human cognition:
Maybe you’re one of the tiny minority of programmers that, like me, already enjoys writing documentation and works hard at doing it right. If so,the rest of this essay is not for you and you can skip it.
Otherwise, you might want to re-read (or at least re-skim) Ground-Truth Documents before continuing. Because ground-truth documents are a special case of a more general reason why you might want to try to change your mindset about documentation.
In that earlier essay I used the term “knowledge capture” in passing. This is a term of art from AI; it refers to the process of extracting domain knowledge from the heads of human experts into a form that can be expressed as an algorithm executable by the literalistic logic of a computer.
What I invite you to think about now is how writing documentation for software you are working on can save you pain and effort by (a) capturing knowledge you have but don’t know you have, and (b) eliciting knowledge that you have not yet developed.
Humans, including me and you, are sloppy and analogical thinkers who tend to solve problems by pattern-matching against noisy data first and checking our intuitions with logic after the fact (if we actually get that far). There’s no point in protesting that it shouldn’t be that way, that we should use rigorous logic all the way down, because our brains simply aren’t wired for that. Evolved cognition is a kludge – more properly, multiple stacks of kludges – developed under selection to be just barely adequate at coping.
This kludginess is revealed by, for example, optical illusions. And by the famous 7±2 result about the very limited sized of the human working set. And the various well-documented ways that human beings are extremely bad at statistical reasoning. And in many other ways …
