Accurate Measurement Quotes

Vulnerability is our most accurate measurement of courage.

But a true and accurate measurement of one’s self-worth is how people feel about the negative aspects of themselves.

I wish there was a machine that could accurately measure sadness, and display it in numbers that you could record. And it would be great if that machine could fit in the palm of your hand. I think of this every time I measure the air in my tires.

Life is a time span where people mostly do not see the wood for the trees, wondering what may be the accurate answers to the numerous questions that they have assembled throughout their life, how they might prevent their perception from contradicting the reality of the world of their daily experience and how they can find out the actual standards to measure the soundness of their assumptions. Whichever way, no matter how they ponder, they have no other choice than keeping on looking for Waldo or for Wally. (“How high is too far?”)

I find I can get a more accurate measure of a man when he’s not aware he’s being appraised.

A lie's true power cannot be accurately measured by the number of people who believe its deception when it is told, it must be measured by the number of people who will go out after hearing it trying to convince others of its truth.

Even if it were possible to cast my horoscope in this one life, and to make an accurate prediction about my future, it would not be possible to 'show' it to me because as soon as I saw it my future would change by definition. This is why Werner Heisenberg's adaptation of the Hays Office—the so-called principle of uncertainty whereby the act of measuring something has the effect of altering the measurement—is of such importance. In my case the difference is often made by publicity. For example, and to boast of one of my few virtues, I used to derive pleasure from giving my time to bright young people who showed promise as writers and who asked for my help. Then some profile of me quoted someone who disclosed that I liked to do this. Then it became something widely said of me, whereupon it became almost impossible for me to go on doing it, because I started to receive far more requests than I could respond to, let alone satisfy. Perception modifies reality: when I abandoned the smoking habit of more than three decades I was given a supposedly helpful pill called Wellbutrin. But as soon as I discovered that this was the brand name for an antidepressant, I tossed the bottle away. There may be successful methods for overcoming the blues but for me they cannot include a capsule that says: 'Fool yourself into happiness, while pretending not to do so.' I should actually want my mind to be strong enough to circumvent such a trick.

Eratosthenes, the mapmaker who was the first man to accurately measure the size of the Earth, was a librarian.

In other words, stop judging yourself against shiny people. Avoid the shiny people. The shiny people are a lie. Or get to know them enough to realize they aren’t so shiny after all. Shiny people aren’t the enemy. Sometimes we’re the enemy when we listen to our malfunctioning brains that try to tell us that we’re alone in our self-doubt, or that it’s obvious to everyone that we don’t know what the shit we’re doing. Hell, there are probably people out there right now who consider us to be shiny people (bless their stupid, stupid hearts) and that’s pretty much proof that none of our brains can be trusted to accurately measure the value of anyone, much less ourselves. How can we be expected to properly judge ourselves? We know all of our worst secrets. We are biased, and overly critical, and occasionally filled with shame. So you’ll have to just trust me when I say that you are worthy, important, and necessary. And smart. You may ask how I know and I’ll tell you how. It’s because right now? YOU’RE READING. That’s what the sexy people do. Other, less awesome people might currently be in their front yards chasing down and punching squirrels, but not you. You’re quietly curled up with a book designed to make you a better, happier, more introspective person. You win. You are amazing.

The most accurate measurements to date reveal dark energy as the most prominent thing in town, currently responsible for 68 percent of all the mass-energy in the universe; dark matter comprises 27 percent, with regular matter comprising a mere 5 percent.

The degree of intellect necessary to please us is a fairly accurate measure of the degree of our own intellect.

...one of the most accurate ways to detect and measure the activity of God is to note the amount of opposition that is present.

Chaos doesn’t mean that the system is behaving randomly, it means that it is unpredictable because it has many variables, it is too complex to measure, and even if it could be measured, theoretically the measurement cannot be done accurately and the tiniest inaccuracy would change the end result an enormous amount.

Men can do nothing without the make-believe of a beginning. Even science, the strict measurer, is obliged to start with a make-believe unit, and must fix on a point in the stars' unceasing journey when his sidereal clock shall pretend that time is at Nought. His less accurate grandmother Poetry has always been understood to start in the middle; but on reflection it appears that her proceeding is not very different from his; since Science, too, reckons backward as well as forward, divides his unit into billions, and with his clock-finger at Nought really sets off in medias res. No retrospect will take us to the true beginning; and whether our prologue be in heaven or on earth, it is but a fraction of that all-presupposing fact with which our story sets out.

one of the most accurate ways to detect and measure the activity of God is to note the amount of opposition that is present.

Factfulness is … recognizing that a single perspective can limit your imagination, and remembering that it is better to look at problems from many angles to get a more accurate understanding and find practical solutions. To control the single perspective instinct, get a toolbox, not a hammer. • Test your ideas. Don’t only collect examples that show how excellent your favorite ideas are. Have people who disagree with you test your ideas and find their weaknesses. • Limited expertise. Don’t claim expertise beyond your field: be humble about what you don’t know. Be aware too of the limits of the expertise of others. • Hammers and nails. If you are good with a tool, you may want to use it too often. If you have analyzed a problem in depth, you can end up exaggerating the importance of that problem or of your solution. Remember that no one tool is good for everything. If your favorite idea is a hammer, look for colleagues with screwdrivers, wrenches, and tape measures. Be open to ideas from other fields. • Numbers, but not only numbers. The world cannot be understood without numbers, and it cannot be understood with numbers alone. Love numbers for what they tell you about real lives. • Beware of simple ideas and simple solutions. History is full of visionaries who used simple utopian visions to justify terrible actions. Welcome complexity. Combine ideas. Compromise.

The definition of vulnerability is uncertainty, risk, and emotional exposure. But vulnerability is not weakness; it's our most accurate measure of courage. When the barrier is our belief about vulnerability, the question becomes: 'Are we willing to show up and be seen when we can't control the outcome?' When the barrier to vulnerability is about safety, the question becomes: 'Are we willing to create courageous spaces so we can be fully seen?

Vulnerability is our most accurate measure of courage.

The greatness of a community is most accurately measured by the compassionate action of its members.

The thing I’ve learned over the years about advice is that no one can accurately predict the future, but we all think we can. So advice at its best is one person’s limited perspective of the infinite possibilities before you. People’s advice is based on their fears, their experiences, their prejudices, and at the end of the day, their advice is just that: it’s theirs, not yours. When people give you advice, they’re basing it on what they would do, what they can perceive, on what they think you can do. But the bottom line is, while yes, it is true that we are all subject to a series of universal laws, patterns, tides, and currents—all of which are somewhat predictable—you are the first time you’ve ever happened. YOU and NOW are a unique occurrence, of which you are the most reliable measure of all the possibilities.

There is no need to go through life handicapped by past experiences. What others say about you doesn’t matter. How they treated you is inconsequential. The only accurate, eternal, unassailable measure of your worth comes from almighty God, who will one day judge the living and the dead without exception (1 Pet. 4:4–5).

PLANETARIUM Thinking of Caroline Herschel (1750–1848) astronomer, sister of William; and others. A woman in the shape of a monster a monster in the shape of a woman the skies are full of them a woman ‘in the snow among the Clocks and instruments or measuring the ground with poles’ in her 98 years to discover 8 comets she whom the moon ruled like us levitating into the night sky riding the polished lenses Galaxies of women, there doing penance for impetuousness ribs chilled in those spaces of the mind An eye, ‘virile, precise and absolutely certain’ from the mad webs of Uranusborg encountering the NOVA every impulse of light exploding from the core as life flies out of us Tycho whispering at last ‘Let me not seem to have lived in vain’ What we see, we see and seeing is changing the light that shrivels a mountain and leaves a man alive Heartbeat of the pulsar heart sweating through my body The radio impulse pouring in from Taurus I am bombarded yet I stand I have been standing all my life in the direct path of a battery of signals the most accurately transmitted most untranslatable language in the universe I am a galactic cloud so deep so invo- luted that a light wave could take 15 years to travel through me And has taken I am an instrument in the shape of a woman trying to translate pulsations into images for the relief of the body and the reconstruction of the mind.

Clocks cannot measure time. They can count seconds, minutes and hours, but those are not accurate measures of our experience of time. A day of hunger is longer than a day when you've eaten. How quickly time passes isn't constant. An hour can stretch out and seem unending. A year can pass you by before you know it.

When I say you don’t have to explain what you’re going to do with your life, I’m not suggesting you lounge around whining about how difficult it is. I’m suggesting you apply yourself in directions for which we have no accurate measurement. I’m talking about work. And love.

Like a soldier, the carpenter sharpens his own tools. He carries his equipment in his tool box, and works under the direction of his foreman. He makes columns and girders with an axe, shapes floorboards and shelves with a plane, cuts fine openwork and bas reliefs accurately, giving as excellent a finish as his skill will allow. This is the craft of the carpenters. When the carpenter becomes skilled, he works efficiently and according to correct measures. When he has developed practical knowledge of all the skills of the craft, he can become a foreman himself.

And it was true. I always would have guessed it, even all the time that I feared it would never happen. Being there that night was the meaning of my life. Getting there had been my every intention. When I say you don’t have to explain what you’re going to do with your life, I’m not suggesting you lounge around whining about how difficult it is. I’m suggesting you apply yourself in directions for which we have no accurate measurement. I’m talking about work. And love.

can barely recall it myself. How much did I suffer? How much pain did I go through? I wish there was a machine that could accurately measure sadness, and display it in numbers that you could record. And it would be great if that machine could fit in the palm of your hand. I think of this every time I measure the air in my tires.

There is a most profound and beautiful question associated with the observed coupling constant, e - the amplitude for a real electron to emit or absorb a real photon. It is a simple number that has been experimentally determined to be close to 0.08542455. (My physicist friends won't recognize this number, because they like to remember it as the inverse of its square: about 137.03597 with about an uncertainty of about 2 in the last decimal place. It has been a mystery ever since it was discovered more than fifty years ago, and all good theoretical physicists put this number up on their wall and worry about it.) Immediately you would like to know where this number for a coupling comes from: is it related to pi or perhaps to the base of natural logarithms? Nobody knows. It's one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man. You might say the "hand of God" wrote that number, and "we don't know how He pushed his pencil." We know what kind of a dance to do experimentally to measure this number very accurately, but we don't know what kind of dance to do on the computer to make this number come out, without putting it in secretly!

Some employees make products, some make sales; the CEO makes decisions. Therefore, a CEO can most accurately be measured by the speed and quality of those decisions.

When collectively, businesses everywhere are able to accurately measure their carbon footprint, it allows us to collectively make more informed decision.

Though your emotions are always valid and need to be validated, they are hardly ever an accurate measure of what you are capable of in life.

I have accomplished nothing in the last four and a half years," he lamented - a statement that is only accurate when measured against the yardstick of his former life.

A brick could be used to show you how much I love you. Well, maybe not a whole brick, but certainly a half a brick would be an accurate measure for the amount of love I have for you.


Like so many of the decisions to exclude women in the interests of simplicity, from architecture to medical research, this conclusion could only be reached in a culture that conceives of men as the default human and women as a niche aberration. To distort a reality you are supposedly trying to measure makes sense only if you don’t see women as essential. It makes sense only if you see women as an added extra, a complicating factor. It doesn’t make sense if you’re talking about half of the human race. It doesn’t make sense if you care about accurate data.

there is still a kind of unique loneliness to child rearing for women. We so often do it in isolation. Add to the fact that in our competitive, perfectionist culture, in which the price woman are required to pay for freedom still seems to be martyrdom, almost everyone lies about motherhood. Part of that lying is loyalty - I can't let on that my kid is the only one on the playground who can't read or play the piano - and part of it is self-protection, since we've made hyper-motherhood a measure of female success. The preferred answer to the question "How are you?" is always "Fine," and the answer to the question "How are the kids?" is supposed to be "Great!" That's true even if the accurate answers would be "terrible" and "a mess." I think it produces its own kind of desperation, especially for women, who yearn to be emotionally open.

As an extreme measure, Hicks, Porter, Gary Cohn and White House social media director Dan Scavino proposed they set up a committee. They would draft some tweets that they believed Trump would like. If the president had an idea for a tweet, he could write it down or get one of them in and they would vet it. Was it factually accurate? Was it spelled correctly? Did it make sense?

I saw something moving round the foot of the bed, which at first I could not accurately distinguish. But I soon saw that it was a sooty-black animal that resembled a monstrous cat. It appeared to me about four or five feet long for it measured fully the length of the hearthrug as it passed over it; and it continued to-ing and fro-ing with the lithe, sinister restlessness of a beast in a cage. I could not cry out, although as you may suppose, I was terrified. Its pace was growing faster, and the room rapidly darker and darker, and at length so dark that I could no longer see anything of it but its eyes. I felt it spring lightly on the bed. The two broad eyes approached my face, and suddenly I felt a stinging pain as if two large needles darted, an inch or two apart, deep into my breast. I waked with a scream.

The problem with the self-esteem movement is that it measured self-esteem by how positively people felt about themselves. But a true and accurate measurement of one’s self-worth is how people feel about the negative aspects of themselves.

Take a bar of metal and put a single notch in it. The two lengths thus defined have a relationship that can be expressed as the ratio between them. In theory, therefore, any rational number can be expressed with a single mark on a bar of metal. Using a simple alphabetic code, a mark that calculated to a ratio of .1215225 could be read as 12-15-22-5, or “l-o-v-e.” The complete plays of Shakespeare could be written in a single mark, if it were possible to measure accurately enough.

Most girls have a recipe for disaster, but few of them actually find all the ingredients and bake them at the right temperature. If they did, they'd learn to measure more accurately and that they ought to clean up their mess as they go along.

I had come to wonder about the true nature of commitment. In fact, it's not about time. It's not about reliability and predictability. Commitment is about depth. It's about effort. It's about passion. It's about wanting to be in a certain place, and not somewhere else. Of course time is involved; it would be naïve and illogical to suggest otherwise. But commitment is best measured not by the time one is willing to give up but, more accurately, by the energy one wants to put in, by how present one is.

Earlier maps had underestimated the distances to other continents and exaggerated the outlines of individual nations. Now global dimensions could be set, with authority, by the celestial spheres. Indeed, King Louis XIV of France, confronted with a revised map of his domain based on accurate longitude measurements, reportedly complained that he was losing more territory to his astronomers than to his enemies.

Vadderung grinned. “I’ve never heard it phrased quite like that, but it’s accurate enough. In any event, overcoming that inertia requires tremendous energy, will, and a measure of simple luck. If one wishes to alter the course of history, it’s a far simpler matter to attempt to shape the future.

There was but one question he left unasked, and it vibrated between his lines: if gross miscalculations of a person’s value could occur on a baseball field, before a live audience of thirty thousand, and a television audience of millions more, what did that say about the measurement of performance in other lines of work? If professional baseball players could be over-or undervalued, who couldn’t? Bad as they may have been, the statistics used to evaluate baseball players were probably far more accurate than anything used to measure the value of people who didn’t play baseball for a living.

when another German scientist, Werner Heisenberg, formulated his famous uncertainty principle. In order to predict the future position and velocity of a particle, one has to be able to measure its present position and velocity accurately. The obvious way to do this is to shine light on the particle. Some of the waves of light will be scattered by the particle and this will indicate its position. However, one will not be able to determine the position of the particle more accurately than the distance between the wave crests of light, so one needs to use light of a short wavelength in order to measure the position of the particle precisely. Now, by Planck’s quantum hypothesis, one cannot use an arbitrarily small amount of light; one has to use at least one quantum. This quantum will disturb the particle and change its velocity in a way that cannot be predicted. Moreover, the more accurately one measures the position, the shorter the wavelength of the light that one needs and hence the higher the energy of a single quantum. So the velocity of the particle will be disturbed by a larger amount. In other words, the more accurately you try to measure the position of the particle, the less accurately you can measure its speed, and vice versa.

Unlike venous blood drawn from the arm, capillary blood was polluted by fluids from tissues and cells that interfered with tests and made measurements less accurate.

The economy is a test and measurement system, and it requires reliable learning guided by an accurate meter of monetary value.

The last transaction price is the least accurate measure of the fair value.

As a rule, the extent to which politics can become the object of free scientific inquiry is a most accurate barometer by which to measure the degree of academic freedom in a country.

As it turned out, Clark’s shortcomings as a strategist—particularly failing to accurately take the measure of Milosevic—were as nothing in comparison to his deficiencies as a battlefield general.

The problem with the self-esteem movement is that it measured self-esteem by how positively people felt about themselves. But a true and accurate measurement of one’s self-worth is how people feel about the negative aspects of themselves. If a person like Jimmy feels absolutely fucking great 99.9 percent of the time, despite his life falling apart around him, then how can that be a valid metric for a successful and happy life?

Indeed, King Louis XIV of France, confronted with a revised map of his domain based on accurate longitude measurements, reportedly complained that he was losing more territory to his astronomers than to his enemies.

definition of vulnerability is uncertainty, risk, and emotional exposure. But vulnerability is not weakness; it’s our most accurate measure of courage. When the barrier is our belief about vulnerability, the question becomes: Are we willing to show up and be seen when we can’t control the outcome? When the barrier to vulnerability is about safety, the question becomes: Are we willing to create courageous spaces so we can be fully seen?

A brick could be used measure the volume of love in any given bathtub. But for the test to be accurate, I’m going to need you to disrobe and step down here. Don’t worry, I’m already naked and in the water—and it’s warm. 


Labour, therefore, it appears evidently, is the only universal, as well as the only accurate, measure of value, or the only standard by which we can compare the values of different commodities, at all times, and at all places.

wish there was a machine that could accurately measure sadness, and display it in numbers that you could record. And it would be great if that machine could fit in the palm of your hand. I think of this every time I measure the air in my tires.

Bad as they may have been, the statistics used to evaluate baseball players were probably far more accurate than anything used to measure the value of people who didn’t play baseball for a living.

So, based on that, we’d say you’re seven weeks one day along.” I mentally pull up my calendar app in my head. “I’ve kept accurate records. I should be just shy of seven weeks.” “Our measurements might be off, but it’s also likely that you ovulated earlier than you thought you did.” I look at Chase. “The patrol car.” “Seriously?” He lowers his voice though the room is small enough the tech can probably hear him anyway. “Neighborhood Hot Cop knocked you up?” I giggle again at the name of the game we’d played that night. “Yep. Neighborhood Hot Cop knocked me up.

The essence of this knowledge was the ability to `see all' and to `know all'. Was this not precisely the ability Adam and Eve acquired after eating the forbidden fruit, which grew on the branches of the tree of the knowledge of good and evil'? · Finally, just as Adam and Eve were driven out of the Garden, so were the four First Men of the Popol Vuh deprived of their ability to `see far'. Thereafter `their eyes were covered and they could only see what was close ...' Both the Popol Vuh and Genesis therefore tell the story of mankind's fall from grace. In both cases, this state of grace was closely associated with knowledge, and the reader is left in no doubt that the knowledge in question was so remarkable that it conferred godlike powers on those who possessed it. The Bible, adopting a dark and muttering tone of voice, calls it `the knowledge of good and evil' and has nothing further to add. The Popol Vuh is much more informative. It tells us that the knowledge of the First Men consisted of the ability to see `things hidden in the distance', that they were astronomers who `examined the four corners, the four points of the arch of the sky', and that they were geographers who succeeded in measuring `the round face of the earth'. 7 Geography is about maps. In Part I we saw evidence suggesting that the cartographers of an as yet unidentified civilization might have mapped the planet with great thoroughness at an early date. Could the Popol Vuh be transmitting some garbled memory of that same civilization when it speaks nostalgically of the First Men and of the miraculous geographical knowledge they possessed? Geography is about maps, and astronomy is about stars. Very often the two disciplines go hand in hand because stars are essential for navigation on long sea-going voyages of discovery (and long sea-going voyages of discovery are essential for the production of accurate maps). Is it accidental that the First Men of the Popol Vuh were remembered not only for studying `the round face of the earth' but for their contemplation of `the arch of heaven'?

There were times, she knew from experience, when it was best just to continue on rather than to shift directions, even when it didn’t seem as if you were getting anywhere. Your chances of success weren’t always something you could measure accurately. Perseverance in the face of failure counted for something.

Catch only what you've thrown yourself, all is mere skill and little gain; but when you're suddenly the catcher of a ball thrown by an eternal partner with accurate and measured swing towards you, to your center, in an arch from the great bridgebuilding of God: why catching then becomes a power— not yours, a world's.

No American will think it wrong of me if I proclaim that to have the United States at our side was to me the greatest joy. I could not foretell the course of events. I do not pretend to have measured accurately the martial might of Japan, but now at this very moment I knew the United States was in the war, up to the neck and in to the death. So we had won after all! Yes, after Dunkirk; after the fall of France; after the horrible episode of Oran; after the threat of invasion, when, apart from the Air and the Navy, we were an almost unarmed people; after the deadly struggle of the U-boat war -- the first Battle of the Atlantic, gained by a hand's breadth; after seventeen months of lonely fighting and nineteen months of my responsibility in dire stress, we had won the war. England would live; Britain would live; the Commonwealth of Nations and the Empire would live. How long the war would last or in what fashion it would end, no man could tell, nor did I at this moment care. Once again in our long Island history we should emerge, however mauled or mutiliated, safe and victorious. We should not be wiped out. Our history would not come to an end. We might not even have to die as individuals. Hitler's fate was sealed. Mussolini's fate was sealed. As for the Japanese, they would be ground to powder.

we rely upon the voting populace to determine if a candidate’s intellectual abilities “measure up,” an inherently flawed system, as the populace has access only to prepackaged presentations and observations of a candidate in debates and while he or she is giving speeches—hardly an adequate database for accurately gauging intellectual ability.

Experts in diagnostic errors provided an answer to the puzzle that had been nagging me: How was it possible for missed diagnoses to be so common and yet not perceived by doctors as a major problem? The problem is that physicians, while generally aware that mistakes happen, greatly underestimate how often they make them. In his talks to doctors on the topic, Graber often asks how many have made a diagnostic error in the past year; typically, only about 1 percent of the hands go up. 'The concept that they, personally, could err at a significant rate is inconceivable to most physicians,' he writes. In short, they think it's the other guy. This overconfidence is not necessarily their fault: doctors simply do not get the feedback needed to gain an accurate sense of their batting average. They assume their diagnoses are correct until they hear otherwise. Since there are few, if any, health care organizations that systematically measure diagnostic error rates, they typically learn of their mistakes only from the patients themselves.

Whuffie recaptured the true essence of money: in the old days, if you were broke but respected, you wouldn’t starve; contrariwise, if you were rich and hated, no sum could buy you security and peace. By measuring the thing that money really represented—your personal capital with your friends and neighbors—you more accurately gauged your success.

Of all the lists I’ve made of goals, and all the visions I’ve had, it never before occurred to me that I could be this specific, that I could aspire to a goal actually measurable in inches. I wonder if this is how successful people do it. I wonder if the difference between success and failure could more accurately be described in the waist sizes for jeans.

ask yourself a simple question: What would happen if everyone did it? This is a very easy measure, and a very accurate one. If everyone did a thing, and the result was of ultimate benefit to the human race, then that is “evolved.” If everyone did it and it brought disaster to the human race, then that is not a very “elevated” thing to recommend. Do you agree?

Form was a matter of precise measurement. Without the underpinning of accurate scaffolding, no piece of artwork succeeded. But for all of that, art was instinct, too. One felt the balance or imbalance. The revelation was something akin to a religious experience: You didn’t know the truth and then you suddenly knew it, and because of it everything was transformed.

however, not very accurate, and so his value for the speed of light was 140,000 miles per second, compared to the modern value of 186,000 miles per second. Nevertheless, Roemer’s achievement, in not only proving that light travels at a finite speed, but also in measuring that speed, was remarkable—coming as it did eleven years before Newton’s publication of Principia Mathematica.

As ages passed, people learned from their ancestors. The more accurately you knew the position and movements of the Sun and Moon and stars, the more reliably you could predict when to hunt, when to sow and reap, when to gather the tribes. As precision of measurement improved, records had to be kept, so astronomy encouraged observation and mathematics and the development of writing.

The Glock is lighter by a good measure than the Beretta I was trained on, with a better grip, and I’ve heard it’s accurate, but weapons are like cars—you know they have standard stuff like lights and an ignition and windshield wipers, but it still takes a few seconds to figure them out when they’re unfamiliar. So I burn precious moments getting a feel for it before I’m ready to point and shoot—

And that’s the trap of marginal thinking. You can see the immediate costs of investing, but it’s really hard to accurately see the costs of not investing. When you decide that the upside of investing in the new product isn’t substantial enough while you still have a perfectly acceptable existing product, you aren’t taking into account a future in which somebody else brings the new product to market. You’re assuming everything else—specifically, the money you make on the old product—will continue forever exactly as it has up until now. A company may not see any consequences of that decision for some time. It might not get “caught” in the short term if a competitor doesn’t get ahead. But the company that makes all its decisions through this marginal-costs lens will, eventually, pay the price.

This is a promising new source of insight that can supplement survey data but can’t replace it for the foreseeable future. That’s because the tools have a ways to go before they can accurately gauge sentiment about specific customer interactions as precisely and consistently as a survey. You should consider this option when your measurement program matures, but start out with the tried-and-true approach of fielding surveys.

The operation of a market economy is dependent on prices, and prices, to be accurate, are dependent on a common medium of exchange, which reflects the relative scarcity of different goods. If this is easy money, the ability of its issuer to constantly increase its quantity will prevent it from accurately reflecting opportunity costs. Every unpredictable change in the quantity of money would distort its role as a measure of interpersonal value and a conduit for economic information.

The evidence presented by the ancient maps appears to suggest the existence in remote times, before the rise of any of the known cultures, of a true civilization, of a comparatively advanced sort, which either was localized in one area but had worldwide commerce, or was, in a real sense, a worldwide culture. This culture, at least in some respects, may well have been more advanced than the civilizations of Egypt, Babylonia, Greece, and Rome. In astronomy, nautical science, mapmaking and possibly ship-building, it was perhaps more advanced than any state of culture before the 18th Century of the Christian Era. It was in the 18th Century that we first developed a practical means of finding longitude. It was in the 18th Century that we first accurately measured the circumference of the earth. Not until the 19th Century did we begin to send out ships for purposes of whaling or exploration into the Arctic or Antarctic Seas. The maps indicate that some ancient people may have done all these things.

Roger Bacon, a Franciscan monk, was arguably the greatest mathematician of the thirteenth century. Bishop Robert Grosseteste was the first man to write down the necessary steps for performing a scientific experiment. Jesuits had built the first reflecting telescopes, microscopes, barometers, were first to calculate the constant of gravity, the first to measure the height of the mountains on the moon, the first to develop an accurate method of calculating a planet’s orbit, the first to devise and publish a coherent description of atomic theory.

Even without world wars, revolutions and emigration, siblings growing up in the same home almost never share the same environment. More accurately, brothers and sisters share some environments — usually the less important ones — but they rarely share the one single environment that has the most powerful impact on personality formation. They may live in the same house, eat the same kinds of food, partake in many of the same activities. These are environments of secondary importance. Of all environments, the one that most profoundly shapes the human personality is the invisible one: the emotional atmosphere in which the child lives during the critical early years of brain development. The invisible environment has little to do with parenting philosophies or parenting style. It is a matter of intangibles, foremost among them being the parents’ relationship with each other and their emotional balance as individuals. These, too, can vary significantly from the birth of one child to the arrival of another. Psychological tension in the parents’ lives during the child’s infancy is, I am convinced, a major and universal influence on the subsequent emergence of ADD. A hidden factor of great importance is a parent’s unconscious attitude toward a child: what, or whom, on the deepest level, the child represents for the parents; the degree to which the parents see themselves in the child; the needs parents may have that they subliminally hope the child will meet. For the infant there exists no abstract, “out-there” reality. The emotional milieu with which we surround the child is the world as he experiences it. In the words of the child psychiatrist and researcher Margaret Mahler, for the newborn, the parent is “the principal representative of the world.” To the infant and toddler, the world reveals itself in the image of the parent: in eye contact, intensity of glance, body language, tone of voice and, above all, in the day-today joy or emotional fatigue exhibited in the presence of the child. Whatever a parent’s intention, these are the means by which the child receives his or her most formative communications. Although they will be of paramount importance for development of the child’s personality, these subtle and often unconscious influences will be missed on psychological questionnaires or observations of parents in clinical settings. There is no way to measure a softening or an edge of anxiety in the voice, the warmth of a smile or the depth of furrows on a brow. We have no instruments to gauge the tension in a father’s body as he holds his infant or to record whether a mother’s gaze is clouded by worry or clear with calm anticipation. It may be said that no two children have exactly the same parents, in that the parenting they each receive may vary in highly significant ways. Whatever the hopes, wishes or intentions of the parent, the child does not experience the parent directly: the child experiences the parenting. I have known two siblings to disagree vehemently about their father’s personality during their childhood. Neither has to be wrong if we understand that they did not receive the same fathering, which is what formed their experience of the father. I have even seen subtly but significantly different mothering given to a pair of identical twins.

You want a physicist to speak at your funeral. You want the physicist to talk to your grieving family about the conservation of energy, so they will understand that your energy has not died. You want the physicist to remind your sobbing mother about the first law of thermodynamics; that no energy gets created in the universe, and none is destroyed. You want your mother to know that all your energy, every vibration, every Btu of heat, every wave of every particle that was her beloved child remains with her in this world. You want the physicist to tell your weeping father that amid energies of the cosmos, you gave as good as you got. And at one point you’d hope that the physicist would step down from the pulpit and walk to your brokenhearted spouse there in the pew and tell him that all the photons that ever bounced off your face, all the particles whose paths were interrupted by your smile, by the touch of your hair, hundreds of trillions of particles, have raced off like children, their ways forever changed by you. And as your widow rocks in the arms of a loving family, may the physicist let her know that all the photons that bounced from you were gathered in the particle detectors that are her eyes, that those photons created within her constellations of electromagnetically charged neurons whose energy will go on forever. And the physicist will remind the congregation of how much of all our energy is given off as heat. There may be a few fanning themselves with their programs as he says it. And he will tell them that the warmth that flowed through you in life is still here, still part of all that we are, even as we who mourn continue the heat of our own lives. And you’ll want the physicist to explain to those who loved you that they need not have faith; indeed, they should not have faith. Let them know that they can measure, that scientists have measured precisely the conservation of energy and found it accurate, verifiable and consistent across space and time. You can hope your family will examine the evidence and satisfy themselves that the science is sound and that they’ll be comforted to know your energy’s still around. According to the law of the conservation of energy, not a bit of you is gone; you’re just less orderly. Amen.

The idea of an achievement gap means there is a disparity in academic performance between groups of students; implicit in this idea is that academic achievement as measured by statistical instruments like test scores and dropout rates is the only form of academic “achievement.” There is an even more sinister implication in achievement-gap talk—that disparities in academic achievement accurately reflect disparities in intelligence among racial groups. Intellect is the linchpin of behavior, and the racist idea of the achievement gap is the linchpin of behavioral racism.

Measuring the strength of a workplace can be simplified to twelve questions. These twelve questions don’t capture everything you may want to know about your workplace, but they do capture the most information and the most important information. They measure the core elements needed to attract, focus, and keep the most talented employees. Here they are: Do I know what is expected of me at work? Do I have the materials and equipment I need to do my work right? At work, do I have the opportunity to do what I do best every day? In the last seven days, have I received recognition or praise for doing good work? Does my supervisor, or someone at work, seem to care about me as a person? Is there someone at work who encourages my development? At work, do my opinions seem to count? Does the mission/purpose of my company make me feel my job is important? Are my co-workers committed to doing quality work? Do I have a best friend at work? In the last six months, has someone at work talked to me about my progress? This last year, have I had opportunities at work to learn and grow? These twelve questions are the simplest and most accurate way to measure the strength of a workplace.

As the third evening approached, Gabriel looked up blearily as two people entered the room. His parents. The sight of them infused him with relief. At the same time, their presence unlatched all the wretched emotion he'd kept battened down until this moment. Disciplining his breathing, he stood awkwardly, his limbs stiff from spending hours on the hard chair. His father came to him first, pulling him close for a crushing hug and ruffling his hair before going to the bedside. His mother was next, embracing him with her familiar tenderness and strength. She was the one he'd always gone to first whenever he'd done something wrong, knowing she would never condemn or criticize, even when he deserved it. She was a source of endless kindness, the one to whom he could entrust his worst thoughts and fears. "I promised nothing would ever harm her," Gabriel said against her hair, his voice cracking. Evie's gentle hands patted his back. "I took my eyes off her when I shouldn't have," he went on. "Mrs. Black approached her after the play- I pulled the bitch aside, and I was too distracted to notice-" He stopped talking and cleared his throat harshly, trying not to choke on emotion. Evie waited until he calmed himself before saying quietly, "You remember when I told you about the time your f-father was badly injured because of me?" "That wasn't because of you," Sebastian said irritably from the bedside. "Evie, have you harbored that absurd idea for all these years?" "It's the most terrible feeling in the world," Evie murmured to Gabriel. "But it's not your fault, and trying not to make it so won't help either of you. Dearest boy, are you listening to me?" Keeping his face pressed against her hair, Gabriel shook his head. "Pandora won't blame you for what happened," Evie told him, "any more than your father blamed me." "Neither of you are to blame for anything," his father said, "except for annoying me with this nonsense. Obviously the only person to blame for this poor girl's injury is the woman who attempted to skewer her like a pinioned duck." He straightened the covers over Pandora, bent to kiss her forehead gently, and sat in the bedside chair. "My son... guilt, in proper measure, can be a useful emotion. However, when indulged to excess it becomes self-defeating, and even worse, tedious." Stretching out his long legs, he crossed them negligently. "There's no reason to tear yourself to pieces worrying about Pandora. She's going to make a full recovery." "You're a doctor now?" Gabriel asked sardonically, although some of the weight of grief and worry lifted at his father's confident pronouncement. "I daresay I've seen enough illness and injuries in my time, stabbings included, to predict the outcome accurately. Besides, I know the spirit of this girl. She'll recover." "I agree," Evie said firmly. Letting out a shuddering sigh, Gabriel tightened his arms around her. After a long moment, he heard his mother say ruefully, "Sometimes I miss the days when I could solve any of my children's problems with a nap and a biscuit." "A nap and a biscuit wouldn't hurt this one at the moment," Sebastian commented dryly. "Gabriel, go find a proper bed and rest for a few hours. We'll watch over your little fox cub.

REQUIREMENTS TO BE GREAT AT RUNNING HR What kind of person should you look for to comprehensively and continuously understand the quality of your management team? Here are some key requirements:   World-class process design skills Much like the head of quality assurance, the head of HR must be a masterful process designer. One key to accurately measuring critical management processes is excellent process design and control.   A true diplomat Nobody likes a tattletale and there is no way for an HR organization to be effective if the management team doesn’t implicitly trust it. Managers must believe that HR is there to help them improve rather than police them. Great HR leaders genuinely want to help the managers and couldn’t care less about getting credit for identifying problems. They will work directly with the managers to get quality up and only escalate to the CEO when necessary. If an HR leader hoards knowledge, makes power plays, or plays politics, he will be useless.   Industry knowledge Compensation, benefits, best recruiting practices, etc. are all fast-moving targets. The head of HR must be deeply networked in the industry and stay abreast of all the latest developments.   Intellectual heft to be the CEO’s trusted adviser None of the other skills matter if the CEO does not fully back the head of HR in holding the managers to a high quality standard. In order for this to happen, the CEO must trust the HR leader’s thinking and judgment.   Understanding things unspoken When management quality starts to break down in a company, nobody says anything about it, but super-perceptive people can tell that the company is slipping. You need one of those.

As we grow up in civilized society, we are measured, evaluated, educated and trained, licensed and credentialed, and are eventually classified and assigned our place. In the process, we become very attached to this artificial identity that has been thrust upon us and very reluctant to set foot outside of it. (When we do, it is often when we are on vacation. It may therefore be helpful to think of this transition as going on a permanent vacation.) But if we overcome one fear—the fear of losing our assigned place in society—then many other fears fall away. Rational fears—ones that are based on an accurate perception of danger—do and should remain, but the irrational fear of stepping outside yourself and becoming someone else tends to disappear. And this opens us up to making dramatic changes, adapting to new circumstances and environments and, in the process, setting ourselves free.

Natural examples of chaotic dynamical systems include the earth’s atmosphere and the vibrations of virtually all sources of musical sound, such as the scrape of a bow on the strings or the turbulent flow of air from the player’s lips over the fipple of a flute. Small differences in initial conditions can be amplified by such systems to such an extent that any error in measuring the initial conditions can render any long-range forecast of system behavior wildly inaccurate, even if there is no further disturbance to the system. The weather from day to day is never exactly the same. Notes played on a flute, though they may sound alike, are never exactly the same. Our ears gloss over these differences, hearing sound categorically. But if we wish to understand the precise mechanism of a dynamical system so as to accurately predict its behavior over time, the initial conditions must be known exactly.

The investigation described in the subsequent pages bears close relation to three sciences. It was approached by the author from the standpoint of astronomy and a desire to understand the variations of the sun. It was hoped that these variations could be more accurately studied by correlation with climatic phenomena. But the science of meteorology is still comparatively new and supplies us only with a few decades of records on which to base our conclusions. So botanical aid was sought in order to extend our knowledge of weather changes over hundreds and even thousands of years by making use of the dependence of the annual rings of trees in dry climates on the annual rainfall. If the relationship sought proves to be real, the rings in the trunks of trees give us not only a means of studying climatic changes through long periods of years, but perhaps also of tracing changes in solar activity during the same time. Thus astronomy, meteorology, and botany join in a study to which each contributes essential parts and from which, it is hoped, each may gain a small measure of benefit.

THE BUCCAL CELL SMEAR TEST (EXATest) Using cells gently scraped from an area in the mouth between the bottom teeth and the back of the tongue provides an accurate means of measuring the amount of magnesium in the cells of the body. Measuring cellular magnesium in this way indicates the amount of magnesium in heart and muscle cells, the two major body tissues affected by magnesium deficiency. The buccal cell smear test can be used to sample many things in cells; however, IntraCellular Diagnostics has developed a testing procedure called EXATest specifically to identify the amounts of certain minerals in the cell. The company sends sampling kits to your doctor’s office, where a simple procedure, which takes about 60 seconds, is performed. Your doctor uses a wooden spatula to scrape off superficial layers of cells under your tongue. The scrapings are carefully placed on a microscope slide and sent back to the lab. A special electron microscope then measures the amount of magnesium and other minerals in the sample on the slide. The results are sent back to your doctor. The test is expensive but may be covered by Medicare and insurance.

After surgery, we talked again, this time discussing chemo, radiation, and prognosis. By this point, I had learned a couple of basic rules. First, detailed statistics are for research halls, not hospital rooms. The standard statistic, the Kaplan-Meier curve, measures the number of patients surviving over time. It is the metric by which we gauge progress, by which we understand the ferocity of a disease. For glioblastoma, the curve drops sharply until only about 5 percent of patients are alive at two years. Second, it is important to be accurate, but you must always leave some room for hope. Rather than saying, “Median survival is eleven months” or “You have a ninety-five percent chance of being dead in two years,” I’d say, “Most patients live many months to a couple of years.” This was, to me, a more honest description. The problem is that you can’t tell an individual patient where she sits on the curve: Will she die in six months or sixty? I came to believe that it is irresponsible to be more precise than you can be accurate. Those apocryphal doctors who gave specific numbers (“ The doctor told me I had six months to live”): Who were they, I wondered, and who taught them statistics?

Humans have undoubtedly evolved mechanisms that assess their own mate value relative to others in their social environment. Ancestral environments were populated with relatively small groups of people containing around 50 to 150 individuals. Assessments of relative mate value were probably fairly accurate. One function of accurate assessments would have been to focus attraction tactics on potential mates within their own mate value range. In our current environment, however, the population is substantially larger, and the images to which individuals are exposed through television and the internet show an unprecedented comparison standard. Fashion models and actresses, for example, are often highly physically attractive. Extremely attractive women are a tiny fraction of the population, yet images of these women are presented at a misleadingly high frequency. This might have the effect of artificially lowering women’s judgments of their value as a potential mate relative to competitors in the local pool of potential mates. This, in turn, might escalate intrasexual competition between women or cause them to take drastic measures to try to increase their attractiveness—a possible cause of body image problems, eating disorders such as anorexia and bulimia, or depression (Faer et al., 2005).

I have just spoken of that morbid condition of the auditory nerve which rendered all music intolerable to the sufferer, with the exception of certain effects of stringed instruments. It was, perhaps, the narrow limits to which he thus confined himself upon the guitar which gave birth, in great measure, to the fantastic character of his performances. But the fervid facility of his impromptus could not be so accounted for. They must have been, and were, in the notes, as well as in the words of his wild fantasies (for he not unfrequently accompanied himself with rhymed verbal improvisations), the result of that intense mental collectedness and concentration to which I have previously alluded as observable only in particular moments of the highest artificial excitement. The words of one of these rhapsodies I have easily remembered. I was, perhaps, the more forcibly impressed with it as he gave it, because, in the under or mystic current of its meaning, I fancied that I perceived, and for the first time, a full consciousness on the part of Usher of the tottering of his lofty reason upon her throne. The verses, which were entitled “The Haunted Palace,” ran very nearly, if not accurately, thus:— I. In the greenest of our valleys, By good angels tenanted, Once a fair and stately palace— Radiant palace—reared its head. In the monarch Thought’s dominion— It stood there! Never seraph spread a pinion Over fabric half so fair. II. Banners yellow, glorious, golden, On its roof did float and flow (This—all this—was in the olden Time long ago); And every gentle air that dallied, In that sweet day, Along the ramparts plumed and pallid, A winged odor went away. III. Wanderers in that happy valley Through two luminous windows saw Spirits moving musically To a lute’s well-timed law; Round about a throne, where sitting (Porphyrogene!) In state his glory well befitting, The ruler of the realm was seen. IV. And all with pearl and ruby glowing Was the fair palace door, Through which came flowing, flowing, flowing And sparkling evermore, A troop of Echoes whose sweet duty Was but to sing, In voices of surpassing beauty, The wit and wisdom of their king. V. But evil things, in robes of sorrow, Assailed the monarch’s high estate; (Ah, let us mourn, for never morrow Shall dawn upon him, desolate!) And, round about his home, the glory That blushed and bloomed Is but a dim-remembered story Of the old time entombed. VI. And travellers now within that valley, Through the red-litten windows see Vast forms that move fantastically To a discordant melody; While, like a rapid ghastly river, Through the pale door; A hideous throng rush out forever, And laugh—but smile no more.

The second development, in 1960, was the development of a new technology that allowed researchers for the first time ever to measure accurately the level of hormones circulating in the bloodstream. It was the invention of Rosalyn Yalow, a medical physicist, and Solomon Berson, a physician, and was called the radioimmunoassay. When Yalow won the Nobel Prize for the work in 1977 (Berson by then was not alive to share it), the Nobel Foundation would describe it aptly as bringing about “a revolution in biological and medical research.” Those interested in obesity could now finally answer the questions about which the pre–World War II European clinicians could only speculate: which hormones were regulating the storage of fat in fat cells and its use for fuel by the rest of the body? Answers began coming with the very first publications out of Yalow and Berson’s laboratory and were swiftly confirmed by others. As it turns out, virtually all hormones work to mobilize fat from fat cells so that it can then be used for fuel. Hormones are signaling our bodies to act—flee or fight, reproduce, grow—and they also signal the fat cells to make available the fuel necessary for these actions. The one dominant exception to this fuel-mobilization signaling is insulin, the same hormone that researchers still assumed in the early 1960s to be deficient in all cases of diabetes. Insulin, Yalow and Berson reported, can be thought of as orchestrating how the body uses or “partitions” the fuel it takes in.

Most countries that make great economic and social progress are not democracies. South Korea moved from Level 1 to Level 3 faster than any country had ever done (without finding oil), all the time as a military dictatorship. Of the ten countries with the fastest economic growth in 2016, nine of them score low on democracy. Anyone who claims that democracy is a necessity for economic growth and health improvements will risk getting contradicted by reality. It’s better to argue for democracy as a goal in itself instead of as a superior means to other goals we like. There is no single measure—not GDP per capita, not child mortality (as in Cuba), not individual freedom (as in the United States), not even democracy—whose improvement will guarantee improvements in all the others. There is no single indicator through which we can measure the progress of a nation. Reality is just more complicated than that. The world cannot be understood without numbers, nor through numbers alone. A country cannot function without a government, but the government cannot solve every problem. Neither the public sector nor the private sector is always the answer. No single measure of a good society can drive every other aspect of its development. It’s not either/or. It’s both and it’s case-by-case. Factfulness Factfulness is … recognizing that a single perspective can limit your imagination, and remembering that it is better to look at problems from many angles to get a more accurate understanding and find practical solutions. To control the single perspective instinct, get a toolbox, not a hammer.

To claim that mathematics is purely a human invention and is successful in explaining nature only because of evolution and natural selection ignores some important facts in the nature of mathematics and in the history of theoretical models of the universe. First, while the mathematical rules (e.g., the axioms of geometry or of set theory) are indeed creations of the human mind, once those rules are specified, we lose our freedom. The definition of the Golden Ratio emerged originally from the axioms of Euclidean geometry; the definition of the Fibonacci sequence from the axioms of the theory of numbers. Yet the fact that the ratio of successive Fibonacci numbers converges to the Golden Ratio was imposed on us-humans had not choice in the matter. Therefore, mathematical objects, albeit imaginary, do have real properties. Second, the explanation of the unreasonable power of mathematics cannot be based entirely on evolution in the restricted sense. For example, when Newton proposed his theory of gravitation, the data that he was trying to explain were at best accurate to three significant figures. Yet his mathematical model for the force between any two masses in the universe achieved the incredible precision of better than one part in a million. Hence, that particular model was not forced on Newton by existing measurements of the motions of planets, nor did Newton force a natural phenomenon into a preexisting mathematical pattern. Furthermore, natural selection in the common interpretation of that concept does not quite apply either, because it was not the case that five competing theories were proposed, of which one eventually won. Rather, Newton's was the only game in town!

As an experiment, I tweaked the questions using Kelly’s “Did I do my best to” formulation. • Did I do my best to be happy? • Did I do my best to find meaning? • Did I do my best to have a healthy diet? • Did I do my best to be a good husband? Suddenly, I wasn’t being asked how well I performed but rather how much I tried. The distinction was meaningful to me because in my original formulation, if I wasn’t happy or I ignored Lyda, I could always blame it on some factor outside myself. I could tell myself I wasn’t happy because the airline kept me on the tarmac for three hours (in other words, the airline was responsible for my happiness). Or I overate because a client took me to his favorite barbecue joint, where the food was abundant, caloric, and irresistible (in other words, my client—or was it the restaurant?—was responsible for controlling my appetite). Adding the words “did I do my best” added the element of trying into the equation. It injected personal ownership and responsibility into my question-and-answer process. After a few weeks using this checklist, I noticed an unintended consequence. Active questions themselves didn’t merely elicit an answer. They created a different level of engagement with my goals. To give an accurate accounting of my effort, I couldn’t simply answer yes or no or “30 minutes.” I had to rethink how I phrased my answers. For one thing, I had to measure my effort. And to make it meaningful—that is, to see if I was trending positively, actually making progress—I had to measure on a relative scale, comparing the most recent day’s effort with previous days. I chose to grade myself on a 1-to-10 scale, with 10 being the best score. If I scored low on trying to be happy, I had only myself to blame. We may not hit our goals every time, but there’s no excuse for not trying. Anyone can try.

And observe, you are put to stern choice in this matter. You must either make a tool of the creature, or a man of him. You cannot make both. Men were not intended to work with the accuracy of tools, to be precise and perfect in all their actions. If you will have that precision out of them, and make their fingers measure degrees like cog-wheels, and their arms strike curves like com-passes, you must unhumanize them. All the energy of their spirits must be given to make cogs and compasses of themselves. All their attention and strength must go to the accomplishment of the mean act. The eye of the soul must be bent upon the finger-point, and the soul's force must fill all the invisible nerves that guide it, ten hours a day, that it may not err from its steely precision, and so soul and sight be worn away, and the whole human being be lost at last - a heap of sawdust, so far as its intellectual work in this world is concerned. saved only by its Heart, which cannot go into the form of cogs and compasses, but expands, after the ten hours are over, into fireside humanity. On the other hand, if you will make a man of the working creature, you cannot make a tool. Let him but begin to imagine, to think, to try to do anything worth doing, and the engine-turned precision is lost at once. Out come all his roughness, all his dulness, all his incapability; shame upon shame, failure upon failure, pause after pause: but out comes the whole majesty of him also; and we know the height of it only when we see the clouds settling upon him. And, whether the clouds be bright or dark, there will be transfiguration behind and within them. And now, reader, look round this English room of yours, about which you have been proud so often, because the work of it was so good and strong, and the ornaments of it so finished. Examine again all those accurate mouldings, and perfect polishings, and unerring adjustments of the seasoned wood and tempered steel. Many a time you have exulted over them, and thought how great England was, because her slightest work was done so thoroughly. Alas! if read rightly, these perfectnesses are signs of a slavery in our England.

Robert Rosenthal found a way. He approached a California public elementary school and offered to test the school’s students with a newly developed intelligence-identification tool, called the Harvard Test of Inflected Acquisition, which could accurately predict which children would excel academically in the coming year. The school naturally agreed, and the test was administered to the entire student body. A few weeks later, teachers were provided with the names of the children (about 20 percent of the student body) who had tested as high-potentials. These particular children, the teachers were informed, were special. Though they might not have performed well in the past, the test indicated that they possessed “unusual potential for intellectual growth.” (The students were not informed of the test results.) The following year Rosenthal returned to measure how the high-potential students had performed. Exactly as the test had predicted, the first- and second-grade high-potentials had succeeded to a remarkable degree: The first-graders gained 27 IQ points (versus 12 points for the rest of the class); and the second-graders gained 17 points (versus 7 points). In addition, the high-potentials thrived in ways that went beyond measurement. They were described by their teachers as being more curious, happier, better adjusted, and more likely to experience success as adults. What’s more, the teachers reported that they had enjoyed teaching that year more than any year in the past. Here’s the twist: the Harvard Test of Inflected Acquisition was complete baloney. In fact, the “high-potentials” had been selected at random. The real subject of the test was not the students but the narratives that drive the relationship between the teachers and the students. What happened, Rosenthal discovered, was replacing one story—These are average kids—with a new one—These are special kids, destined to succeed—served as a locator beacon that reoriented the teachers, creating a cascade of behaviors that guided the student toward that future. It didn’t matter that the story was false, or that the children were, in fact, randomly selected. The simple, glowing idea—This child has unusual potential for intellectual growth—aligned motivations, awareness, and behaviors.

One key characteristic of structure is its richness. To illustrate, recall the comparison that John Rawls drew between checkers and chess when he was describing the Aristotelian principle (see page 386). Both games are played on a board with 64 squares, but they have different structures. Checkers has one kind of piece, while chess has six different kinds of pieces. The movement of any checker piece is restricted to a single square per turn unless it is capturing, while movement in chess is different for each piece. In checkers, the goal is to capture all the opponents’ pieces. In chess, the goal is to trap one particular piece. The structure of chess is objectively richer than the structure of checkers. It is no coincidence that chess has thousands of books written about tactics and strategy for every aspect of the game while checkers has a fraction of that number. The nature of accomplishment in checkers and chess is also objectively different, as reflected in their relative places in Western culture.[1] I measure the richness of a structure by three aspects: principles, craft, and tools. The scientific method offers convenient examples. Conceptually, a scientific experiment proceeds according to principles such as replicability, falsifiability, and the role of the hypothesis that apply across different scientific disciplines. The actual conduct of a classic scientific experiment involves craft—the generation of a hypothesis to be tested or a topic to be explored, the creation of the methods for doing so, and meticulous observance of protocols and procedures during the actual work. The details of craft differ not only across disciplines but within disciplines. They also have a family resemblance, in the sense that a meticulous scientist behaves in ways that are recognizable to scientists in every field—“meticulous” being one of the defining characteristics of craft practiced at a high level. Tools play a double role. Sometimes they are created in direct response to needs generated by principles and craft—accurate thermometers are an example—but at least as often, a tool turns out to have unanticipated uses that alter both principles and craft, independently expanding the realm of things a discipline can achieve. An example is the invention of the diffraction grating to study spectra of light, which 40 years later turned out to enable astronomers to study the composition of the stars.

Several teams of German psychologists that have studied the RAT in recent years have come up with remarkable discoveries about cognitive ease. One of the teams raised two questions: Can people feel that a triad of words has a solution before they know what the solution is? How does mood influence performance in this task? To find out, they first made some of their subjects happy and others sad, by asking them to think for several minutes about happy or sad episodes in their lives. Then they presented these subjects with a series of triads, half of them linked (such as dive, light, rocket) and half unlinked (such as dream, ball, book), and instructed them to press one of two keys very quickly to indicate their guess about whether the triad was linked. The time allowed for this guess, 2 seconds, was much too short for the actual solution to come to anyone’s mind. The first surprise is that people’s guesses are much more accurate than they would be by chance. I find this astonishing. A sense of cognitive ease is apparently generated by a very faint signal from the associative machine, which “knows” that the three words are coherent (share an association) long before the association is retrieved. The role of cognitive ease in the judgment was confirmed experimentally by another German team: manipulations that increase cognitive ease (priming, a clear font, pre-exposing words) all increase the tendency to see the words as linked. Another remarkable discovery is the powerful effect of mood on this intuitive performance. The experimenters computed an “intuition index” to measure accuracy. They found that putting the participants in a good mood before the test by having them think happy thoughts more than doubled accuracy. An even more striking result is that unhappy subjects were completely incapable of performing the intuitive task accurately; their guesses were no better than random. Mood evidently affects the operation of System 1: when we are uncomfortable and unhappy, we lose touch with our intuition. These findings add to the growing evidence that good mood, intuition, creativity, gullibility, and increased reliance on System 1 form a cluster. At the other pole, sadness, vigilance, suspicion, an analytic approach, and increased effort also go together. A happy mood loosens the control of System 2 over performance: when in a good mood, people become more intuitive and more creative but also less vigilant and more prone to logical errors. Here again, as in the mere exposure effect, the connection makes biological sense. A good mood is a signal that things are generally going well, the environment is safe, and it is all right to let one’s guard down. A bad mood indicates that things are not going very well, there may be a threat, and vigilance is required. Cognitive ease is both a cause and a consequence of a pleasant feeling.

Similarly, the computers used to run the software on the ground for the mission were borrowed from a previous mission. These machines were so out of date that Bowman had to shop on eBay to find replacement parts to get the machines working. As systems have gone obsolete, JPL no longer uses the software, but Bowman told me that the people on her team continue to use software built by JPL in the 1990s, because they are familiar with it. She said, “Instead of upgrading to the next thing we decided that it was working just fine for us and we would stay on the platform.” They have developed so much over such a long period of time with the old software that they don’t want to switch to a newer system. They must adapt to using these outdated systems for the latest scientific work. Working within these constraints may seem limiting. However, building tools with specific constraints—from outdated technologies and low bitrate radio antennas—can enlighten us. For example, as scientists started to explore what they could learn from the wait times while communicating with deep space probes, they discovered that the time lag was extraordinarily useful information. Wait times, they realized, constitute an essential component for locating a probe in space, calculating its trajectory, and accurately locating a target like Pluto in space. There is no GPS for spacecraft (they aren’t on the globe, after all), so scientists had to find a way to locate the spacecraft in the vast expanse. Before 1960, the location of planets and objects in deep space was established through astronomical observation, placing an object like Pluto against a background of stars to determine its position.15 In 1961, an experiment at the Goldstone Deep Space Communications Complex in California used radar to more accurately define an “astronomical unit” and help measure distances in space much more accurately.16 NASA used this new data as part of creating the trajectories for missions in the following years. Using the data from radio signals across a wide range of missions over the decades, the Deep Space Network maintained an ongoing database that helped further refine the definition of an astronomical unit—a kind of longitudinal study of space distances that now allows missions like New Horizons to create accurate flight trajectories. The Deep Space Network continued to find inventive ways of using the time lag of radio waves to locate objects in space, ultimately finding that certain ways of waiting for a downlink signal from the spacecraft were less accurate than others. It turned to using the antennas from multiple locations, such as Goldstone in California and the antennas in Canberra, Australia, or Madrid, Spain, to time how long the signal took to hit these different locations on Earth. The time it takes to receive these signals from the spacecraft works as a way to locate the probes as they are journeying to their destination. Latency—or the different time lag of receiving radio signals on different locations of Earth—is the key way that deep space objects are located as they journey through space. This discovery was made possible during the wait times for communicating with these craft alongside the decades of data gathered from each space mission. Without the constraint of waiting, the notion of using time as a locating feature wouldn’t have been possible.

To paint after nature is to transfer three-dimensional corporeality to a two-dimensional surface. This you can do if you are in good health and not colorblind. Oil paint, canvas, and brush are material and tools. It is possible by expedient distribution of oil paint on canvas to copy natural impressions; under favorable conditions you can do it so accurately that the picture cannot be distinguished from the model. You start, let us say, with a white canvas primed for oil painting and sketch in with charcoal the most discernible lines of the natural form you have chosen. Only the first line may be drawn more or less arbitrarily, all the others must form with the first the angle prescribed by the natural model. By constant comparison of the sketch with the model, the lines can be so adjusted that the lines of the sketch will correspond to those of the model. Lines are now drawn by feeling, the accuracy of the feeling is checked and measured by comparison of the estimated angle of the line with the perpendicular in nature and in the sketch. Then, according to the apparent proportions between the parts of the model, you sketch in the proportions between parts on the canvas, preferably by means of broken lines delimiting these parts. The size of the first part is arbitrary, unless your plan is to represent a part, such as the head, in 'life size.' In that case you measure with a compass an imaginary line running parallel to a plane on the natural object conceived as a plane on the picture, and use this measurement in representing the first part. You adjust all the remaining parts to the first through feeling, according to the corresponding parts of the model, and check your feeling by measurement; to do this, you place the picture so far away form you that the first part appears as large in the painting as the model, and then you compare. In order to check a given proportion, you hold out the handle of your paintbrush at arm's length towards this proportion in such a way that the end of the thumbnail on the handle coincides with the other end of the proportion. If then you hold the paintbrush out towards the picture, again at arm's length, you can, by the measurement thus obtained, determine with photographic accuracy whether your feeling has deceived you. If the sketch is correct, you fill in the parts of the picture with color, according to nature. The most expedient method is to begin with a clearly recognizable color of large area, perhaps with a somewhat broken blue. You estimate the degree of matness and break the luminosity with a complimentary color, ultramarine, for example, with light ochre. By addition of white you can make the color light, by addition of black dark. All this can be learned. The best way of checking for accuracy is to place the picture directly beside the projected picture surface in nature, return to your old place and compare the color in your picture with the natural color. By breaking those tones that are too bright and adding those that are still lacking, you will achieve a color tonality as close as possible to that in nature. If one tone is correct, you can put the picture back in its place and adjust the other colors to the first by feeling. You can check your feeling by comparing every tone directly with nature, after setting the picture back beside the model. If you have patience and adjust all large and small lines, all forms and color tones according to nature, you will have an exact reproduction of nature. This can be learned. This can be taught. And in addition, you can avoid making too many mistakes in 'feeling' by studying nature itself through anatomy and perspective and your medium through color theory. That is academy.
