Purposive Sampling Quotes

All health, beauty, intelligence, and social grace has been teased from a vast butcher’s yard of unbounded carnage, requiring incalculable eons of massacre to draw forth even the subtlest of advantages. This is not only a matter of the bloody grinding mills of selection, either, but also of the innumerable mutational abominations thrown up by the madness of chance, as it pursues its directionless path to some negligible preservable trait, and then — still further — of the unavowable horrors that ‘fitness’ (or sheer survival) itself predominantly entails. We are a minuscule sample of agonized matter, comprising genetic survival monsters, fished from a cosmic ocean of vile mutants, by a pitiless killing machine of infinite appetite. (This is still, perhaps, to put an irresponsibly positive spin on the story, but it should suffice for our purposes here.)

According to a 1995 study, a sample of Japanese eighth graders spent 44 percent of their class time inventing, thinking, and actively struggling with underlying concepts. The study's sample of American students, on the other hand, spent less than 1 percent of their time in that state. “The Japanese want their kids to struggle,” said Jim Stigler, the UCLA professor who oversaw the study and who cowrote The Teaching Gap with James Hiebert. “Sometimes the [Japanese] teacher will purposely give the wrong answer so the kids can grapple with the theory. American teachers, though, worked like waiters. Whenever there was a struggle, they wanted to move past it, make sure the class kept gliding along. But you don't learn by gliding.

The political merchandisers appeal only to the weak­nesses of voters, never to their potential strength. They make no attempt to educate the masses into becoming fit for self-government; they are content merely to manipulate and exploit them. For this pur­pose all the resources of psychology and the social sciences are mobilized and set to work. Carefully se­lected samples of the electorate are given "interviews in depth." These interviews in depth reveal the uncon­scious fears and wishes most prevalent in a given so­ciety at the time of an election. Phrases and images aimed at allaying or, if necessary, enhancing these fears, at satisfying these wishes, at least symbolically, are then chosen by the experts, tried out on readers and audiences, changed or improved in the light of the information thus obtained. After which the political campaign is ready for the mass communicators. All that is now needed is money and a candidate who can be coached to look "sincere." Under the new dispen­sation, political principles and plans for specific action have come to lose most of their importance. The person­ality of the candidate and the way he is projected by the advertising experts are the things that really mat­ter. In one way or another, as vigorous he-man or kindly father, the candidate must be glamorous. He must also be an entertainer who never bores his audience. Inured to television and radio, that audience is accustomed to being distracted and does not like to be asked to con­centrate or make a prolonged intellectual effort. All speeches by the entertainer-candidate must therefore be short and snappy. The great issues of the day must be dealt with in five minutes at the most -- and prefera­bly (since the audience will be eager to pass on to something a little livelier than inflation or the H-bomb) in sixty seconds flat. The nature of oratory is such that there has always been a tendency among politicians and clergymen to over-simplify complex is­sues. From a pulpit or a platform even the most con­scientious of speakers finds it very difficult to tell the whole truth. The methods now being used to merchan­dise the political candidate as though he were a deo­dorant positively guarantee the electorate against ever hearing the truth about anything.

A man selling Vaseline Petroleum Jelly had gone around a number of houses in town a week before and had left some samples, asking people to see if they could find an ingenious use for it. Now he went around to the same houses, asking what uses they had found for Vaseline. The man in the first house, a wealthy city gent, said, "I used it for medicinal purposes. Whenever my children scraped their elbows or knees, I would rub it on." The man in the second house said, "I used it for mechanical purposes, such as greasing the bearings of my bicycles and lawnmower." The man in the third house, a scruffy, unshaven, working class fellow, said, "I used it for sexual purposes." In a shocked voice the salesman asked, "What do you mean?" "Well," said the scruffy man, "I put a whole lot of it on the handle of my bedroom door to keep the kids out!" You can give the same thing to different people and they will come out with different uses, according to their own unconsciousness. But if they are conscious, they will find only one use.

If tissue samples--including blood cells--became patients' property, researchers taking them without consent and property rights up front would risk being charged with theft. The press ran story after story quoting lawyers and scientists saying that a victory for Moore would "create chaos for researcher" and [sound] the death knell to the university physician-scientist." They called it "a threat to the sharing of tissue for research purposes," and worried that patients would block the progress of science by holding out for excessive profits, even with cells that aren't worth, millions like Moore's.

him to turn out and find a dry twig; and if he can't do it, go and borrow one. In fact, the Leather Stocking Series ought to have been called the Broken Twig Series. I am sorry there is not room to put in a few dozen instances of the delicate art of the forest, as practised by Natty Bumppo and some of the other Cooperian experts. Perhaps we may venture two or three samples. Cooper was a sailor — a naval officer; yet he gravely tells us how a vessel, driving towards a lee shore in a gale, is steered for a particular spot by her skipper because he knows of an undertow there which will hold her back against the gale and save her. For just pure woodcraft, or sailorcraft, or whatever it is, isn't that neat? For several years Cooper was daily in the society of artillery, and he ought to have noticed that when a cannon-ball strikes the ground it either buries itself or skips a hundred feet or so; skips again a hundred feet or so — and so on, till finally it gets tired and rolls. Now in one place he loses some "females" — as he always calls women — in the edge of a wood near a plain at night in a fog, on purpose to give Bumppo a chance to show off the delicate art of the forest before the

Even when money and your finances are an acute priority, it literally pays to focus on the value you're bringing to others. When researchers followed a longitudinal sample of 4660 people over nine years, they found that having a sense of purpose in the first year of the study (based on a standard assessment of purpose in life) was associated with higher levels of both income and net worth over time. What's more, even when they controlled for other variables like life satisfaction and socioeconomic status, people with a sense of purpose at at work also had significantly higher incomes at the end of those nine years.

What's the trouble?" I said, knowing well what that trouble was. "I've a notion in my head that would make the most splendid story that was ever written. Do let me write it out here. It's such a notion!" There was no resisting the appeal. I set him a table; he hardly thanked me, but plunged into the work at once. For half an hour the pen scratched without stopping. Then Charlie sighed and tugged his hair. The scratching grew slower, there were more erasures, and at last ceased. The finest story in the world would not come forth. "It looks such awful rot now," he said, mournfully. "And yet it seemed so good when I was thinking about it. What's wrong?" I could not dishearten him by saying the truth. So I answered: "Perhaps you don't feel in the mood for writing." "Yes I do--except when I look at this stuff. Ugh!" "Read me what you've done," I said. "He read, and it was wondrous bad, and he paused at all the specially turgid sentences, expecting a little approval; for he was proud of those sentences, as I knew he would be. "It needs compression," I suggested, cautiously. "I hate cutting my things down. I don't think you could alter a word here without spoiling the sense. It reads better aloud than when I was writing it." "Charlie, you're suffering from an alarming disease afflicting a numerous class. Put the thing by, and tackle it again in a week." "I want to do it at once. What do you think of it?" "How can I judge from a half-written tale? Tell me the story as it lies in your head." Charlie told, and in the telling there was everything that his ignorance had so carefully prevented from escaping into the written word. I looked at him, and wondering whether it were possible that he did not know the originality, the power of the notion that had come in his way? It was distinctly a Notion among notions. Men had been puffed up with pride by notions not a tithe as excellent and practicable. But Charlie babbled on serenely, interrupting the current of pure fancy with samples of horrible sentences that he purposed to use. I heard him out to the end. It would be folly to allow his idea to remain in his own inept hands, when I could do so much with it. Not all that could be done indeed; but, oh so much!

When my condition improved I made up my mind to go away, to go somewhere where people would never find me again, like a dog with distemper who knows that he is going to die or like the birds that hide themselves when the time to die has come. Early one morning I rose, dressed, took a couple of cakes that were lying on the top shelf and, without attracting anyone’s attention, fled from the house. I was running away from my own misery. I walked aimlessly along the streets, I wandered without set purpose among the rabble-men as they hurried by, an expression of greed on their faces, in pursuit of money and sexual satisfaction. I had no need to see them since any one of them was a sample of the lot. Each and every one of them consisted only of a mouth and a wad of guts hanging from it, the whole terminating in a set of genitals.

We see three men standing around a vat of vinegar. Each has dipped his finger into the vinegar and has tasted it. The expression on each man's face shows his individual reaction. Since the painting is allegorical, we are to understand that these are no ordinary vinegar tasters, but are instead representatives of the "Three Teachings" of China, and that the vinegar they are sampling represents the Essence of Life. The three masters are K'ung Fu-tse (Confucius), Buddha, and Lao-tse, author of the oldest existing book of Taoism. The first has a sour look on his face, the second wears a bitter expression, but the third man is smiling. To Kung Fu-tse (kung FOOdsuh), life seemed rather sour. He believed that the present was out step with the past, and that the government of man on earth was out of harmony with the Way of Heaven, the government of, the universe. Therefore, he emphasized reverence for the Ancestors, as well as for the ancient rituals and ceremonies in which the emperor, as the Son of Heaven, acted as intermediary between limitless heaven and limited earth. Under Confucianism, the use of precisely measured court music, prescribed steps, actions, and phrases all added up to an extremely complex system of rituals, each used for a particular purpose at a particular time. A saying was recorded about K'ung Fu-tse: "If the mat was not straight, the Master would not sit." This ought to give an indication of the extent to which things were carried out under Confucianism. To Buddha, the second figure in the painting, life on earth was bitter, filled with attachments and desires that led to suffering. The world was seen as a setter of traps, a generator of illusions, a revolving wheel of pain for all creatures. In order to find peace, the Buddhist considered it necessary to transcend "the world of dust" and reach Nirvana, literally a state of "no wind." Although the essentially optimistic attitude of the Chinese altered Buddhism considerably after it was brought in from its native India, the devout Buddhist often saw the way to Nirvana interrupted all the same by the bitter wind of everyday existence. To Lao-tse (LAOdsuh), the harmony that naturally existed between heaven and earth from the very beginning could be found by anyone at any time, but not by following the rules of the Confucianists. As he stated in his Tao To Ching (DAO DEH JEENG), the "Tao Virtue Book," earth was in essence a reflection of heaven, run by the same laws - not by the laws of men. These laws affected not only the spinning of distant planets, but the activities of the birds in the forest and the fish in the sea. According to Lao-tse, the more man interfered with the natural balance produced and governed by the universal laws, the further away the harmony retreated into the distance. The more forcing, the more trouble. Whether heavy or fight, wet or dry, fast or slow, everything had its own nature already within it, which could not be violated without causing difficulties. When abstract and arbitrary rules were imposed from the outside, struggle was inevitable. Only then did life become sour. To Lao-tse, the world was not a setter of traps but a teacher of valuable lessons. Its lessons needed to be learned, just as its laws needed to be followed; then all would go well. Rather than turn away from "the world of dust," Lao-tse advised others to "join the dust of the world." What he saw operating behind everything in heaven and earth he called Tao (DAO), "the Way." A basic principle of Lao-tse's teaching was that this Way of the Universe could not be adequately described in words, and that it would be insulting both to its unlimited power and to the intelligent human mind to attempt to do so. Still, its nature could be understood, and those who cared the most about it, and the life from which it was inseparable, understood it best.

significantly different? Because the variances are equal, we read the t-test statistics from the top line, which states “equal variances assumed.” (If variances had been unequal, then we would read the test statistics from the second line, “equal variances not assumed.”). The t-test statistic for equal variances for this test is 2.576, which is significant at p = .011.13 Thus, we conclude that the means are significantly different; the 10th graders report feeling safer one year after the anger management program was implemented. Working Example 2 In the preceding example, the variables were both normally distributed, but this is not always the case. Many variables are highly skewed and not normally distributed. Consider another example. The U.S. Environmental Protection Agency (EPA) collects information about the water quality of watersheds, including information about the sources and nature of pollution. One such measure is the percentage of samples that exceed pollution limits for ammonia, dissolved oxygen, phosphorus, and pH.14 A manager wants to know whether watersheds in the East have higher levels of pollution than those in the Midwest. Figure 12.4 Untransformed Variable: Watershed Pollution An index variable of such pollution is constructed. The index variable is called “pollution,” and the first step is to examine it for test assumptions. Analysis indicates that the range of this variable has a low value of 0.00 percent and a high value of 59.17 percent. These are plausible values (any value above 100.00 percent is implausible). A boxplot (not shown) demonstrates that the variable has two values greater than 50.00 percent that are indicated as outliers for the Midwest region. However, the histograms shown in Figure 12.4 do not suggest that these values are unusually large; rather, the peak in both histograms is located off to the left. The distributions are heavily skewed.15 Because the samples each have fewer than 50 observations, the Shapiro-Wilk test for normality is used. The respective test statistics for East and Midwest are .969 (p = .355) and .931 (p = .007). Visual inspection confirms that the Midwest distribution is indeed nonnormal. The Shapiro-Wilk test statistics are given only for completeness; they have no substantive interpretation. We must now either transform the variable so that it becomes normal for purposes of testing, or use a nonparametric alternative. The second option is discussed later in this chapter. We also show the consequences of ignoring the problem. To transform the variable, we try the recommended transformations, , and then examine the transformed variable for normality. If none of these transformations work, we might modify them, such as using x⅓ instead of x½ (recall that the latter is ).16 Thus, some experimentation is required. In our case, we find that the x½ works. The new Shapiro-Wilk test statistics for East and Midwest are, respectively, .969 (p = .361) and .987 (p = .883). Visual inspection of Figure 12.5 shows these two distributions to be quite normal, indeed. Figure 12.5 Transformed Variable: Watershed Pollution The results of the t-test for the transformed variable are shown in Table

Remedies exist for correcting substantial departures from normality, but these remedies may make matters worse when departures from normality are minimal. The first course of action is to identify and remove any outliers that may affect the mean and standard deviation. The second course of action is variable transformation, which involves transforming the variable, often by taking log(x), of each observation, and then testing the transformed variable for normality. Variable transformation may address excessive skewness by adjusting the measurement scale, thereby helping variables to better approximate normality.8 Substantively, we strongly prefer to make conclusions that satisfy test assumptions, regardless of which measurement scale is chosen.9 Keep in mind that when variables are transformed, the units in which results are expressed are transformed, as well. An example of variable transformation is provided in the second working example. Typically, analysts have different ways to address test violations. Examination of the causes of assumption violations often helps analysts to better understand their data. Different approaches may be successful for addressing test assumptions. Analysts should not merely go by the result of one approach that supports their case, ignoring others that perhaps do not. Rather, analysts should rely on the weight of robust, converging results to support their final test conclusions. Working Example 1 Earlier we discussed efforts to reduce high school violence by enrolling violence-prone students into classes that address anger management. Now, after some time, administrators and managers want to know whether the program is effective. As part of this assessment, students are asked to report their perception of safety at school. An index variable is constructed from different items measuring safety (see Chapter 3). Each item is measured on a seven-point Likert scale (1 = strongly disagree to 7 = strongly agree), and the index is constructed such that a high value indicates that students feel safe.10 The survey was initially administered at the beginning of the program. Now, almost a year later, the survey is implemented again.11 Administrators want to know whether students who did not participate in the anger management program feel that the climate is now safer. The analysis included here focuses on 10th graders. For practical purposes, the samples of 10th graders at the beginning of the program and one year later are regarded as independent samples; the subjects are not matched. Descriptive analysis shows that the mean perception of

safety at the beginning of the program was 4.40 (standard deviation, SD = 1.00), and one year later, 4.80 (SD = 0.94). The mean safety score increased among 10th graders, but is the increase statistically significant? Among other concerns is that the standard deviations are considerable for both samples. As part of the analysis, we conduct a t-test to answer the question of whether the means of these two distributions are significantly different. First, we examine whether test assumptions are met. The samples are independent, and the variables meet the requirement that one is continuous (the index variable) and the other dichotomous. The assumption of equality of variances is answered as part of conducting the t-test, and so the remaining question is whether the variables are normally distributed. The distributions are shown in the histograms in Figure 12.3.12 Are these normal distributions? Visually, they are not the textbook ideal—real-life data seldom are. The Kolmogorov-Smirnov tests for both distributions are insignificant (both p > .05). Hence, we conclude that the two distributions can be considered normal. Having satisfied these t-test assumptions, we next conduct the t-test for two independent samples. Table 12.1 shows the t-test results. The top part of Table 12.1 shows the descriptive statistics, and the bottom part reports the test statistics. Recall that the t-test is a two-step test. We first test whether variances are equal. This is shown as the “Levene’s test for equality of variances.” The null hypothesis of the Levene’s test is that variances are equal; this is rejected when the p-value of this Levene’s test statistic is less than .05. The Levene’s test uses an F-test statistic (discussed in Chapters 13 and 15), which, other than its p-value, need not concern us here. In Table 12.1, the level of significance is .675, which exceeds .05. Hence, we accept the null hypothesis—the variances of the two distributions shown in Figure 12.3 are equal. Figure 12.3 Perception of High School Safety among 10th Graders Table 12.1 Independent-Samples T-Test: Output Note: SD = standard deviation. Now we go to the second step, the main purpose. Are the two means (4.40 and 4.80)

Appendix 1 Our Family's Core Values and Mission YOUR CORE VALUES What are the most important values in your family? Do your kids know these are critical? Do both parents agree on the ranking of values? This worksheet will help you develop and communicate your top values. A "value" is an ideal that is desirable. It is a quality that we want to model in our own lives and see developed in the lives of our kids. For instance, honesty is a very important value, for without it you can't have trust in your relationships. Take time in writing your answers to the following questions. 1. When time and energy are in short supply, what should we make sure we cover in parenting our children? List a few ideas. Then circle the nonnegotiables. 2. What are the "we'd like to get around to these" values? These are the semi-negotiables. 3. What were the top three values of each of your families of origin (the family you grew up in)? Father Mother 1. 1. 2. 2. 3. 3. 4. Think about a healthy, positive family-one that serves as a role model for you. What would you say are their top three values? 1. 2. 3. 5. What are three or four favorite Scripture verses that communicate elements of a healthy family? 1. 2. 3. 4. Based on these verses, what are the three or four principles from Scripture that you'd like to see evidenced in your family? 1. 2. 3. 4. 6. What values are your "pound the table with passion" values? What are the ones that you feel very strongly about? (You may already have them listed.) To help you with this, complete the following sentences: More families need to ... The problem with today's families is ... DEVELOPING YOUR FAMILY'S MISSION STATEMENT Besides writing out your core values, you will do well to develop a family mission statement (or covenant). These important documents will shape your family. The founders of the United States knew that guiding documents would keep us on course as a fledgling democracy; so too will these documents guide your family as you seek to be purposeful. Sample mission statement: We exist to love each other and advance Gods timeless principles and his kingdom on earth. Complete the following: 1. Our family exists to ... 2. What are some activities or behaviors that you imagine your family carrying out? 3. Describe some qualities of character that you can envision your family being known for. 4. What is unique about your family? What makes you different? What are you known for? What sets you apart? 5. What do you hope to do with and through your family that will outlive you? What noble cause greater than yourselves do you want your family to pursue? 6. With these five questions completed, look for a Scripture that supports the basic ideas of your rough-draft concepts for your family mission statement. If there are several candidates, talk about them thoughtfully and choose one, writing it out here: 7. Using the sample as a template, your five questions and your family Scripture, write a rough draft of your family mission statement: 8. Rewrite the mission statement, keeping the same concepts but changing the order of the mission statement. This is simply to give you two options. 9. Discuss this mission statement as a family if the kids are old enough. Discuss it with a few other friends or extended family members. Any feedback? 10. Pray about your family mission statement for a couple of weeks, asking God to affirm it or help you edit it. Then write up the final version. Consider making a permanent version of your family mission statement to hang on a wall in your home.

In 2000 Martin Seligman took on the presidency of the American Psychological Association. For his presidential address he challenged the profession to shift its focus away from simply describing, studying, and diagnosing the negative aspects of the human condition and to begin devoting more attention to the positive aspects of what it means to be human. Of course, his message was simply a more mainstream embodiment of Abraham Maslow’s ideas from the mid-twentieth century of personal fulfillment as the richest arena of psychology. But since Seligman’s call to action, positive psychology has blossomed into a full-fledged component of the field. The research generated by this change in perspective has been conducted at both the basic and applied levels. It has added to our understanding of a myriad of psychological constructs and has been used to improve the lives of many. Positive psychology is a vast discipline, but a sampling of its relevant aspects includes happiness, psychological well-being, flow/optimal experience, meaning, passion, purpose, authentic leadership, strengths, values, character, and virtue. Graduate education programs in these areas have emerged across the world and continue to expand. How

A landmark study was Granovetter’s PhD thesis, which was built on an unprecedented survey of the job searching behavior of professional, technical, and managerial workers in the Boston suburb of Newton. Granovetter observed that preexisting social networks, rather than market forces, were the primary means by which people found jobs. Almost 56 percent of his sample, he noted, had found their latest job through personal contacts, which he defined as contacts established not with the purpose of finding a job, and that involved mostly friends and family.

Anarchism is the purity of rebellion. A pig who struggles wildly and rends the air with his cries while he is held to be slaughtered, and a baby who kicks and screams when, wanting warmth and his mother's breast, he is made to wait in the cold—these are two samples of natural rebellion. Natural rebellion always inspires either deep sympathy and identification with the rebelling creature, or a stiffening of the heart and an activation of aggressive-defensive mechanisms to silence an accusing truth. This truth is that each living being is an end in itself; that nothing gives a being the right to make another a mere instrument of his purposes.

Whenever there has been a secret police, not just in Germany, people often protest that their files are wholly unreliable, full of distortions and fabrications. How better to test that claim than to see what they had on me? After all, I should know what I was really up to. And what did my officers and informers think they were doing? Can the files, and the men and women behind them, tell us anything more about communism, the Cold War and the sense or nonsense of spying? This systematic opening of secret-police records to every citizen who is in them and wants to know, is without precedent. There has been nothing like it, anywhere, ever. Was it right? What has it done to those involved? The experience may even teach us something about history and memory, about ourselves, about human nature. So if the form of this book seems self-indulgent, the purpose is not. I am but a window, a sample, a means to an end, the object in this experiment. To do this, I must explore not just a file but a life: the life of the person I was then. This is not the same things as 'my life.' What we usually call 'my life' is a constantly rewritten version of our own past. 'My life' is the mental autobiography with which and by which we all live. What really happened is quite another matter. Searching for a lost self, I am also searching for a lost time. And for answers to the question How did the one shape the other? Historical time and personal time, the public and private, great events and our own lives. Writing about the large areas of human experience ignored by conventional political history, the historian Keith Thomas quotes Samuel Johnson: How small, of all that human hearts endure That part which laws or kings can cause or cure. But looking back I see how much the experience of my own heart, at least, was caused by our modern 'laws and kings': by the different regimes of East and West, and the conflict between them. Perhaps, after all, Johnson was expressing not a universal but a purely local truth. Happy the country where that was ever true.

In a more advanced class, you will learn exactly how to calculate degrees of freedom; for our purposes, they are roughly equal to the number of observations in our sample

People sometimes think that all animal experiments serve vital medical purposes and can be justified on the grounds that they relieve more suffering than they cause. This comfortable belief is mistaken. The LD50 – a test designed in the 1920s to find the ‘Lethal Dose’, or level of consumption that will make 50 percent of a sample of animals die – is still used today for some purposes. It is, for example, used to test the popular anti-wrinkle treatment, Botox® Cosmetic. For this purpose, mice are given varying doses. Those given a high enough dose slowly suffocate as their respiratory muscles become paralyzed, undoubtedly after considerable suffering. These tests are not necessary to prevent human suffering: even if there were no alternative to the use of animals to test the safety of the products, it would be better to do without them, and learn to live with wrinkles, as most elderly people always have.

Three individuals were involved: the one running the experiment, the subject of the experiment (a volunteer), and a confederate pretending to be a volunteer. These three people fill three distinct roles: the Experimenter (an authoritative role), the Teacher (a role intended to obey the orders of the Experimenter), and the Learner (the recipient of stimulus from the Teacher). The subject and the actor both drew slips of paper to determine their roles, but unknown to the subject, both slips said "teacher". The actor would always claim to have drawn the slip that read "learner", thus guaranteeing that the subject would always be the "teacher". Next, the "teacher" and "learner" were taken into an adjacent room where the "learner" was strapped into what appeared to be an electric chair. The experimenter told the participants this was to ensure that the "learner" would not escape.[1] The "teacher" and "learner" were then separated into different rooms where they could communicate but not see each other. In one version of the experiment, the confederate was sure to mention to the participant that he had a heart condition.[1] At some point prior to the actual test, the "teacher" was given a sample electric shock from the electroshock generator in order to experience firsthand what the shock that the "learner" would supposedly receive during the experiment would feel like. The "teacher" was then given a list of word pairs that he was to teach the learner. The teacher began by reading the list of word pairs to the learner. The teacher would then read the first word of each pair and read four possible answers. The learner would press a button to indicate his response. If the answer was incorrect, the teacher would administer a shock to the learner, with the voltage increasing in 15-volt increments for each wrong answer. If correct, the teacher would read the next word pair.[1] The subjects believed that for each wrong answer, the learner was receiving actual shocks. In reality, there were no shocks. After the confederate was separated from the subject, the confederate set up a tape recorder integrated with the electroshock generator, which played prerecorded sounds for each shock level. After a number of voltage-level increases, the actor started to bang on the wall that separated him from the subject. After several times banging on the wall and complaining about his heart condition, all responses by the learner would cease.[1] At this point, many people indicated their desire to stop the experiment and check on the learner. Some test subjects paused at 135 volts and began to question the purpose of the experiment. Most continued after being assured that they would not be held responsible. A few subjects began to laugh nervously or exhibit other signs of extreme stress once they heard the screams of pain coming from the learner.[1] If at any time the subject indicated his desire to halt the experiment, he was given a succession of verbal prods by the experimenter, in this order:[1] Please continue. The experiment requires that you continue. It is absolutely essential that you continue. You have no other choice, you must go on.

The way we select the sample is critically important, and it depends largely on the purpose of the study or the aim of the statistical task at hand.

Here was where this Nought truly lived. Quath had sensed its raw, sticky pull in a jolting instant of profound surprise. The mind’s upper layers were mild and obliging, like cool, smooth corridors beneath the linear engagements of the conscious—while far below, in chambers walled and ramified with bony purpose, lurked a complex, ropy labyrinth of strange power. Or minds. Quath was not even sure the Nought was a single intelligence. Its highest echelons had seemed to be more like a passive stage than a directing entity. There, on a broad, level area above the syrupy seethe, factions of the undermind warred. An abyss yawned. Instincts spoke quietly, effectively, never falling silent. Emotions flared prickly hot—heckling, yearning, always calling the higher intelligence away from its deliberations. Zesty hormones surged—not to carry wedges of information or holistic images, as in Quath, but to flood the bloodstream with urgent demands. Organs far from the brain answered these chemical heralds, pumping other hormones into the thumping flow, adding alkaline voices to the babble. Ideas rose like crystalline towers from this swamp, glimmering coolly—but soon were spattered with the aromatic chemical murk, blood on glass. These elements merged and wrestled, struggling armies rushing together in flurries, fermenting, spinning away into wild skirmishes. Lurid splashes festooned the brittle ramparts of analytical thought. A churning mire lapped hungrily at the stern bulwarks of reason, eroding worn salients even as fresh ones were built. Yet somehow this interior battle did not yield mere confusion and scattered indecision. Somehow a single coherent view emerged, holding the vital, fervent factions in check. Its actions sampled of all the myriad influences, letting none dominate for long. Quath marveled at the sheer energy behind the incessant clashings, and at the same time felt a mixture of recognition laced by repulsion. This Nought’s inner landscape was far more complex than it should be. No wonder it had not attained the technological sophistication of the podia!—it labored forward in a howling storm, its every sharp perception blunted by fraying winds of passion.

Once you’ve answered this question for yourself, replace a quick response with one that takes the time to describe the process you identified, points out the current step, and emphasizes the step that comes next. I call this the process-centric approach to e-mail, and it’s designed to minimize both the number of e-mails you receive and the amount of mental clutter they generate. To better explain this process and why it works consider the following process-centric responses to the sample e-mails from earlier: Process-Centric Response to E-mail #1: “I’d love to grab coffee. Let’s meet at the Starbucks on campus. Below I listed two days next week when I’m free. For each day, I listed three times. If any of those day and time combinations work for you, let me know. I’ll consider your reply confirmation for the meeting. If none of those date and time combinations work, give me a call at the number below and we’ll hash out a time that works. Looking forward to it.” Process-Centric Response to E-mail #2: “I agree that we should return to this problem. Here’s what I suggest… “Sometime in the next week e-mail me everything you remember about our discussion on the problem. Once I receive that message, I’ll start a shared directory for the project and add to it a document that summarizes what you sent me, combined with my own memory of our past discussion. In the document, I’ll highlight the two or three most promising next steps. “We can then take a crack at those next steps for a few weeks and check back in. I suggest we schedule a phone call for a month from now for this purpose. Below I listed some dates and times when I’m available for a call. When you respond with your notes, indicate the date and time combination that works best for you and we’ll consider that reply confirmation for the call. I look forward to digging into this problem.” Process-Centric

North Carolina’s Robert Rice Reynolds, who had just that week granted an interview to Hitler’s mouthpiece newspaper, Völkischer Beobachter, headlined “Advice to Roosevelt: Stick to Your Knitting.” A sample of Reynolds’s reasoning: “I can see no reason why the youth of this country should be uniformed to save the so-called democracies of Europe—imperialistic Britain and communistic France…. I am glad to be able to state that I am absolutely against the United States waging war for the purpose of protecting the Jews anywhere in the world.” Among the most outspoken isolationists was the powerful New York congressman Hamilton Fish, who was already heading up the National Committee to Keep America Out of Foreign Wars.

Of course, I’d known before then. But that night, clutching yet another beer bottle, watching Christian move on the dance floor, I verbalized the subtle knowledge in my mind. I loved him. Shamefully and hopelessly. I tried to talk myself out of it. It’s not like there is a definition. They can’t take your blood sample, run a test and give you the results. It’s all vague, subjective, prone to manipulation, hypochondria. You wake up one day thinking you’re in love with someone and the following week, you’re not. All that drama, the cultural pressure. The epitome of so-called happiness sold to us by the media. They say it can last a year, the honeymoon phase. Two at best. In love… It was just a chemical process, imagination, internalization of recycled clichés, and a hefty dose of delusion. But it didn’t hurt any less. I wanted him, craved him, couldn’t bear anyone else to touch him just as I needed him to be content and sheltered—yes, even if it meant he’d be with someone else. Happy and safe. He was the single, most important being in the whole universe. If Christian was hopeful and joyous as ever, my life had a purpose, the world had a meaning.

Discipline #2: Act on the Lead Measures Once you’ve identified a wildly important goal, you need to measure your success. In 4DX, there are two types of metrics for this purpose: lag measures and lead measures. Lag measures describe the thing you’re ultimately trying to improve. For example, if your goal is to increase customer satisfaction in your bakery, then the relevant lag measure is your customer satisfaction scores. As the 4DX authors explain, the problem with lag measures is that they come too late to change your behavior: “When you receive them, the performance that drove them is already in the past.” Lead measures, on the other hand, “measure the new behaviors that will drive success on the lag measures.” In the bakery example, a good lead measure might be the number of customers who receive free samples. This is a number you can directly increase by giving out more samples. As you increase this number, your lag measures will likely eventually improve as well. In other words, lead measures turn your attention to improving the behaviors you directly control in the near future that will then have a positive impact on your long-term goals.

The error in fabrication had been traced to a synthesized tissue sample sent to Genstar weeks before whose base pairs were purposefully arranged to install a computer virus as a result of being sequenced.

The near absence of charts and tables from Freud’s scientific papers might be regarded as a peripheral matter if it weren’t symptomatic of a basic weakness of temperament: a lazy reluctance to collect sufficient evidence to ensure that a given finding wasn’t an anomaly or an artifact of careless procedures. This flaw could go unnoticed so long as Freud was microscopically analyzing dead tissues, any one of which could stand for countless identical others. For the purpose of establishing laws in most fields, though, large samples are indispensable. As a psychologist, Freud would consistently ignore that requirement. Instead, he would rest comprehensive generalizations on untested insights from a few cases or even from just one, his own.

Appearance matters, we see your presentation before we get a chance to sample the substance within. You might miss a chance for the latter.

The ecological complexities of existence overwhelm the human mind, even though some of that richness is an integral part of man's own nature. It is only by isolating some little part of that existence for a short time that it can be momentarily grasped: we learn only from samples. By separating primary from secondary qualities, by making mathematical description the test of truth, by utilizing only a part of the human self to explore only a part of its environment, the new science successfully turned the most significant attributes of life into purely secondary phenomena, ticketed for replacement by the machine. Thus living organisms, in their most typical functions and purposes, became superfluous.

It does not mean that one’s personal experiences constitute a sufficient sample to derive a conclusion about an idea; it is just that one’s personal experience gives the stamp of authenticity and sincerity of opinion. Experience is devoid of the cherry-picking that we find in studies, particularly those called “observational,” ones in which the researcher finds past patterns, and, thanks to the sheer amount of data, can therefore fall into the trap of an invented narrative. Further, in writing, I feel corrupt and unethical if I have to look up a subject in a library as part of the writing itself. This acts as a filter—it is the only filter. If the subject is not interesting enough for me to look it up independently, for my own curiosity or purposes, and I have not done so before, then I should not be writing about it at all, period. It does not mean that libraries (physical and virtual) are not acceptable; it means that they should not be the source of any idea. Students pay to write essays on topics for which they have to derive knowledge from a library as a self-enhancement exercise; a professional who is compensated to write and is taken seriously by others should use a more potent filter. Only distilled ideas, ones that sit in us for a long time, are acceptable—and those that come from reality.

Table 14.1 also shows R-square (R2), which is called the coefficient of determination. R-square is of great interest: its value is interpreted as the percentage of variation in the dependent variable that is explained by the independent variable. R-square varies from zero to one, and is called a goodness-of-fit measure.5 In our example, teamwork explains only 7.4 percent of the variation in productivity. Although teamwork is significantly associated with productivity, it is quite likely that other factors also affect it. It is conceivable that other factors might be more strongly associated with productivity and that, when controlled for other factors, teamwork is no longer significant. Typically, values of R2 below 0.20 are considered to indicate weak relationships, those between 0.20 and 0.40 indicate moderate relationships, and those above 0.40 indicate strong relationships. Values of R2 above 0.65 are considered to indicate very strong relationships. R is called the multiple correlation coefficient and is always 0 ≤ R ≤ 1. To summarize up to this point, simple regression provides three critically important pieces of information about bivariate relationships involving two continuous variables: (1) the level of significance at which two variables are associated, if at all (t-statistic), (2) whether the relationship between the two variables is positive or negative (b), and (3) the strength of the relationship (R2). Key Point R-square is a measure of the strength of the relationship. Its value goes from 0 to 1. The primary purpose of regression analysis is hypothesis testing, not prediction. In our example, the regression model is used to test the hypothesis that teamwork is related to productivity. However, if the analyst wants to predict the variable “productivity,” the regression output also shows the SEE, or the standard error of the estimate (see Table 14.1). This is a measure of the spread of y values around the regression line as calculated for the mean value of the independent variable, only, and assuming a large sample. The standard error of the estimate has an interpretation in terms of the normal curve, that is, 68 percent of y values lie within one standard error from the calculated value of y, as calculated for the mean value of x using the preceding regression model. Thus, if the mean index value of the variable “teamwork” is 5.0, then the calculated (or predicted) value of “productivity” is [4.026 + 0.223*5 =] 5.141. Because SEE = 0.825, it follows that 68 percent of productivity values will lie 60.825 from 5.141 when “teamwork” = 5. Predictions of y for other values of x have larger standard errors.6 Assumptions and Notation There are three simple regression assumptions. First, simple regression assumes that the relationship between two variables is linear. The linearity of bivariate relationships is easily determined through visual inspection, as shown in Figure 14.2. In fact, all analysis of relationships involving continuous variables should begin with a scatterplot. When variable

What turned heads was the finding from the blood samples. Participants scoring high on the hedonic scale were far more likely to have inflammatory gene expression and decreased expression of genes involved in antibody and antiviral response, whereas participants scoring high on the eudaimonic scale had the opposite pattern of expression. In other words, participants with greater eudaimonia were physiologically healthier. As the researchers state, “Hedonic and eudaimonic well-being were originally distinguished to resolve basic and ancient philosophical questions regarding the best way for humans to live. The present data offer little grounds to prefer one mode of happiness over the other based on affective experience, but they identify a stark contrast at the level of molecular physiology.” But before we assume that Angelina Jolie will live to be 140 and Paris Hilton will explode in a giant ball of pus, we should do what scientists like to do when something as radical as this is found: more research.

All worldly experiences provide opportunities for personal growth. We must each follow our passion to discover personal happiness. I am compelled to obey the law of my own being, no matter what the consequences, even if it leads to disaster or death. High-minded people might take a different trail. Well-meaning people might envision a different path for us. Our life is not a group project; we must give birth to our own vision. We must look inside ourselves to discern what our humanity demands of us, and then give expression to our sacred seed of inwardness. A person lives part of his or her life sampling its rich offering, discovering what resonates with oneself. Experimentation leads to growth, growth leads to knowledge, which in turn leads to wisdom.

The scorecard is composed of three parts: the job’s mission, outcomes, and competencies. Together, these three pieces describe A performance in the role—what a person must accomplish, and how. They provide a clear linkage between the people you hire and your strategy. MISSION: THE ESSENCE OF THE JOB The mission is an executive summary of the job’s core purpose. It boils the job down to its essence so everybody understands why you need to hire someone into the slot. Take a look at the sample scorecard on the next page. The mission for the VP of sales clearly captures why the role exists: to grow revenue through direct contacts with industrial customers.
