Improvement Science Quotes

We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.

It's much easier on the emotions when one sees life as an experiment rather than a struggle for popularity.

The love of money is the root of all evil, therefore selfishness must be the seed.

A human being always acts and feels and performs in accordance with what he imagines to be true about himself and his environment...For imagination sets the goal ‘picture’ which our automatic mechanism works on. We act, or fail to act, not because of ‘will,’ as is so commonly believed, but because of imagination.

Joy is found when you focus your energy on improving human dignity, human capacity and human values.

Simple minded people do things like gossip, lie, spread rumors, and cause troubles. But, I know you're more intelligent.

In conclusion, it appears that nothing can be more improving to a young naturalist, than a journey in distant countries.

Science is arguably the most effective religion because it is the first religion that is able to evolve and improve upon itself.

If no one had ever challenged religious authority, there’d be no democracy, no public schools, women’s rights, improvements to science and medicine, evolution of slavery and no laws against child abuse or spousal abuse. I was afraid to challenge my religious beliefs because that was the basis of creation—mine anyway. I was afraid to question the Bible or anything in it, and when I did, that’s when I became involved with PFLAG and realized that my son was a perfectly normal human being and there was nothing for God to heal because Bobby was perfect just the way he was.

If only the scientific experts could come up with something to get it out of our minds. One cup of fixit fizzle that will lift the dirt from our lives, soften our hardness, protect our inner parts, improve our processing, reduce our yellowing and wrinkling, improve our natural color, and make us sweet and good.

It's the same with the wound in our hearts. We need to give them our attention so that they can heal. Otherwise the wounds continue to cause us pain. Sometimes for a very long time. We're all going to get hurt. But here's the trick - they also serve an amazing purpose. When our hearts are wounded that's when they open. We grow through pain. We grow through difficult situations. That's why you have to embrace each and every difficult thing in your life.

Understanding human nature must be the basis of any real improvement in human life. Science has done wonders in mastering the laws of the physical world, but our own nature is much less understood, as yet, than the nature of stars and electrons. When science learns to understand human nature, it will be able to bring a happiness into our lives which machines and the physical sciences have failed to create.

Pick a leader who will make their citizens proud. One who will stir the hearts of the people, so that the sons and daughters of a given nation strive to emulate their leader's greatness. Only then will a nation be truly great, when a leader inspires and produces citizens worthy of becoming future leaders, honorable decision makers and peacemakers. And in these times, a great leader must be extremely brave. Their leadership must be steered only by their conscience, not a bribe.

We either win or we learn. So take the fuck-ups as new ways of getting good information about yourself.

Pick a leader who will keep jobs in your country by offering companies incentives to hire only within their borders, not one who allows corporations to outsource jobs for cheaper labor when there is a national employment crisis. Choose a leader who will invest in building bridges, not walls. Books, not weapons. Morality, not corruption. Intellectualism and wisdom, not ignorance. Stability, not fear and terror. Peace, not chaos. Love, not hate. Convergence, not segregation. Tolerance, not discrimination. Fairness, not hypocrisy. Substance, not superficiality. Character, not immaturity. Transparency, not secrecy. Justice, not lawlessness. Environmental improvement and preservation, not destruction. Truth, not lies.

The best way to avoid abuses is for the populace in general to be scientifically literate, to understand the implications of such investigations. In exchange for freedom of inquiry, scientists are obliged to explain their work. If science is considered a closed priesthood, too difficult and arcane for the average person to understand, the dangers of abuse are greater. But if science is a topic of general interest and concern - if both its delights and its social consequences are discussed regularly and competently in the schools, the press, and at the dinner table - we have greatly improved our prospects for learning how the world really is and for improving both it and us.

It is common knowledge among psychologists that most of us underrate ourselves, short-change ourselves, sell ourselves short. Actually, there is no such thing as a superiority complex. People who seem to have one are actually suffering from feelings of inferiority; their "superior" self is a fiction, a coverup, to hide from themselves and others their deep-down feelings of inferiority and insecurity.

Practice that’s spaced out, interleaved with other learning, and varied produces better mastery, longer retention, and more versatility. But these benefits come at a price: when practice is spaced, interleaved, and varied, it requires more effort. You feel the increased effort, but not the benefits the effort produces. Learning feels slower from this kind of practice, and you don’t get the rapid improvements and affirmations you’re accustomed to seeing from massed practice.

Humans may crave absolute certainty; they may aspire to it; they may pretend, as partisans of certain religions do, to have attained it. But the history of science — by far the most successful claim to knowledge accessible to humans — teaches that the most we can hope for is successive improvement in our understanding, learning from our mistakes, an asymptotic approach to the Universe, but with the proviso that absolute certainty will always elude us.

It’s more important to be good ancestors than dutiful descendants. Too many people spend their lives being custodians of the past instead of stewards of the future. We worry about making our parents proud when we should be focused on making our children proud. The responsibility of each generation is not to please our predecessors—it’s to improve conditions for our successors.

One student asks: Why should I live? Steven Pinker answers: In the very act of asking that question, you are seeking reasons for your convictions, and so you are committed to reason as the means to discover and justify what is important to you. And there are so many reasons to live! As a sentient being, you have the potential to flourish. You can refine your faculty of reason itself by learning and debating. You can seek explanations of the natural world through science, and insight into the human condition through the arts and humanities. You can make the most of your capacity for pleasure and satisfaction, which allowed your ancestors to thrive and thereby allowed you to exist. You can appreciate the beauty and richness of the natural and cultural world. As the heir to billions of years of life perpetuating itself, you can perpetuate life in turn. You have been endowed with a sense of sympathy—the ability to like, love, respect, help, and show kindness—and you can enjoy the gift of mutual benevolence with friends, family, and colleagues. And because reason tells you that none of this is particular to you, you have the responsibility to provide to others what you expect for yourself. You can foster the welfare of other sentient beings by enhancing life, health, knowledge, freedom, abundance, safety, beauty, and peace. History shows that when we sympathize with others and apply our ingenuity to improving the human condition, we can make progress in doing so, and you can help to continue that progress.

Every conscious thought you have, every moment you spend on an idea, is a commitment to be stuck with that idea and with aspects of that level of thinking, for the rest of your life. Spending just 10 seconds focusing on a topic that does not serve your interests is to invest your energy along a path that will continue to draw from you and define you.

Death is the midwife of very great things.... It brings about the birth and rebirth of forms a thousand times improved. This is the highest mystery of God.

Random mutations much more easily debilitate genes than improve them, and that this is true even of the helpful mutations. Let me emphasize, our experience with malaria’s effects on humans (arguably our most highly studied genetic system) shows that most helpful mutations degrade genes. What’s more, as a group the mutations are incoherent, meaning that they are not adding up to some new system. They are just small changes - mostly degradative - in pre-existing, unrelated genes. The take-home lesson is that this is certainly not the kind of process we would expect to build the astonishingly elegant machinery of the cell. If random mutation plus selective pressure substantially trashes the human genome, why should we think that it would be a constructive force in the long term? There is no reason to think so.

When I applied to graduate school many years ago, I wrote an essay expressing my puzzlement at how a country that could put a man on the moon could still have people sleeping on the streets. Part of that problem is political will; we could take a lot of people off the streets tomorrow if we made it a national priority. But I have also come to realize that NASA had it easy. Rockets conform to the unchanging laws of physics. We know where the moon will be at a given time; we know precisely how fast a spacecraft will enter or exist the earth's orbit. If we get the equations right, the rocket will land where it is supposed to--always. Human beings are more complex than that. A recovering drug addict does not behave as predictably as a rocket in orbit. We don't have a formula for persuading a sixteen-year-old not to drop out of school. But we do have a powerful tool: We know that people seek to make themselves better off, however they may define that. Our best hope for improving the human condition is to understand why we act the way we do and then plan accordingly. Programs, organizations, and systems work better when they get the incentives right. It is like rowing downstream.

I cannot, however, but think that the world would be better and brighter if our teachers would dwell on the Duty of Happiness as well as the Happiness of Duty; for we ought to be as cheerful as we can, if only because to be happy ourselves is a most effectual contribution to the happiness of others.

Is it not time to cry that the blind shall see, the deaf hear, the lame walk? But that which fanaticism formerly promised to its elect, science now accomplishes for all men.

The secret to improving at a skill is to retain some degree of conscious control over it while practicing—to force oneself to stay out of autopilot.

Improving intelligence is possible, but it is more likely to occur if children are given the right experiences at the right ages.

One of the prominent features of exercise, which is sometimes not appreciated in studies, is an improvement in the rate of learning,

It is always necessary to jump up and down on the scaffold of knowledge to make sure it is solid. If you are skeptical about a scientific claim, then jump up and down on it as hard as you can until you expose a weakness or convince yourself that it is solid.

In all, 86 per cent of the increased life expectancy was due to decreases in infectious diseases. And the bulk of the decline in infectious disease deaths occurred prior to the age of antibiotics. Less than 4 per cent of the total improvement in life expectancy since 1700s can be credited to twentieth-century advances in medical care.

Bryson DeChambeau uses science in the true sense of the word to improve his golf game. He experiments and analyzes data to get better, and this separates golf fans, because those who think that's not cool use all of their brain capacity just breathing, like amoebas, but dumber.

The single most powerful item in our preventive tool kit is exercise, which has a two-pronged impact on Alzheimer’s disease risk: it helps maintain glucose homeostasis, and it improves the health of our vasculature

Every machine has had the same history – a long record of sleepless nights and of poverty, of disillusions and of joys, of partial improvements discovered by several generations of nameless workers, who have added to the original invention these little nothings, without which the most fertile idea would remain fruitless. More than that: every new invention is a synthesis, the resultant of innumerable inventions which have preceded it in the vast field of mechanics and industry. Science and industry, knowledge and application, discovery and practical realization leading to new discoveries, cunning of brain and of hand, toil of mind and muscle – all work together. Each discovery, each advance, each increase in the sum of human riches, owes its being to the physical and mental travail of the past and the present. By what right then can anyone whatever appropriate the least morsel of this immense whole and say – This is mine, not yours?

If you believe you can change—if you make it a habit—the change becomes real. This is the real power of habit: the insight that your habits are what you choose them to be. Once that choice occurs—and becomes automatic—it’s not only real, it starts to seem inevitable.

Deficiency in judgement is properly that which is called stupidity; and for such a failing we know no remedy. A dull or narrow-minded person, to whom nothing is wanting but a proper degree of understanding, may be improved by tuition, even so far as to deserve the epithet of learned. But as such persons frequently labour under a deficiency in the faculty of judgement, it is not uncommon to find men extremely learned who in the application of their science betray a lamentable degree this irremediable want.]

This leads us to the strengths of being less than confident. Confidence makes it very hard for us to learn and improve. When we think we know all the answers, we stop looking for them. Marshall Goldsmith says, “Although our self-confident delusions can help us achieve, they can make it difficult for us to change.” When

If an Elder shall give us a lecture upon astronomy, chemistry, or geology, our religion embraces it all. It matters not what the subject be, if it tends to improve the mind, exalt the feelings, and enlarge the capacity. The truth that is in all the arts and sciences forms part of our religion. Faith is no more a part of it than any other true principle of philosophy.

Yes! live life with every fibre of one's being, surrender oneself to it, with no thoughts of rebellion, without deluding oneself that one can improve it and render it painless; all this was revealed to the dying man, as the only courageous and wise attitude possible for a man of science.

Science and psychology have isolated the one prime cause for success or failure in life. It is the hidden self-image you have of yourself.

Science gropes and staggers toward improved understanding.

Every interaction is an opportunity to learn, Only if we are interested in improving rather than proving.

In science the credit goes to the man who convinced the world, not to the man to whom the idea first occurs.

That is why our arts and sciences cannot improve the world, despite what liberal philanthropists say. Our vast new scientific skills are first used by the damnably greedy selfish impatient parts of our nature and nation, the careful kindly social part always comes second.

JACK: Yes, but said yourself that a severe chill was not hereditary. ALGERNON: It usen't to be, I know - but I daresay it is now. Science is always making wonderful improvements in things.

The act of retrieving learning from memory has two profound benefits. One, it tells you what you know and don’t know, and therefore where to focus further study to improve the areas where you’re weak. Two, recalling what you have learned causes your brain to reconsolidate the memory, which strengthens its connections to what you already know and makes it easier for you to recall in the future.

One reason we can change our brains simply by imagining is that, from a neuroscientific point of view, imagining an act and doing it are not as different as they sound. When people close their eyes and visualize a simple object, such as the letter a, the primary visual cortex lights up, just as it would if the subjects were actually looking at the letter a. Brain scans show that in action and imagination many of the same parts of the brain are activated. That is why visualizing can improve performance.

Feminism can be a friend to science. It not only improves how science is done by pushing researchers to include the female perspective, but science in turn can also show us that we're not as different as we seem. Research to date suggests that humans survived, thrived and spread across the globe through the efforts of everyone equally sharing the same work and responsibilities. For most of our history, we lived hand in hand. And our biology reflects this.

Intellectual and moral growth is no less indispensable than material improvement. To know is a sacrament, to think is the prime necessity, truth is nourishment as well as grain. A reason which fasts from science and wisdom grows thin.

The great age of the earth will appear greater to man when he understands the origin of living organisms and the reasons for the gradual development and improvement of their organization. This antiquity will appear even greater when he realizes the length of time and the particular conditions which were necessary to bring all the living species into existence. This is particularly true since man is the latest result and present climax of this development, the ultimate limit of which, if it is ever reached, cannot be known.

Though many of my arguments will be coolly analytical — that an acknowledgment of human nature does not, logically speaking, imply the negative outcomes so many people fear — I will not try to hide my belief that they have a positive thrust as well. "Man will become better when you show him what he is like," wrote Chekhov, and so the new sciences of human nature can help lead the way to a realistic, biologically informed humanism. They expose the psychological unity of our species beneath the superficial differences of physical appearance and parochial culture. They make us appreciate the wondrous complexity of the human mind, which we are apt to take for granted precisely because it works so well. They identify the moral intuitions that we can put to work in improving our lot. They promise a naturalness in human relationships, encouraging us to treat people in terms of how they do feel rather than how some theory says they ought to feel. They offer a touchstone by which we can identify suffering and oppression wherever they occur, unmasking the rationalizations of the powerful. They give us a way to see through the designs of self-appointed social reformers who would liberate us from our pleasures. They renew our appreciation for the achievements of democracy and of the rule of law. And they enhance the insights of artists and philosophers who have reflected on the human condition for millennia.

The science of man is the only solid foundation for the other sciences. [All the other sciences] have a relation, greater or lesser, to human nature. ‘Tis impossible to tell what changes and improvements we might make in these sciences were we thoroughly acquainted with the extent and force of human understanding, and could explain the nature of the ideas we employ, and of the operations we perform in our reason.

It be urged that the wild and uncultivated tree, hitherto yielding sour and bitter fruit only, can never be made to yield better; yet we know that the grafting art implants a new tree on the savage stock, producing what is most estimable in kind and degree. Education, in like manner, engrafts a new man on the native stock, and improves what in his nature was vicious and perverse into qualities of virtue and social worth.

{Yogananda on the death of his dear friend, the eminent 20th century scientist, Luther Burbank} His heart was fathomlessly deep, long acquainted with humility, patience, sacrifice. His little home amid the roses was austerely simple; he knew the worthlessness of luxury, the joy of few possessions. The modesty with which he wore his scientific fame repeatedly reminded me of the trees that bend low with the burden of ripening fruits; it is the barren tree that lifts its head high in an empty boast. I was in New York when, in 1926, my dear friend passed away. In tears I thought, 'Oh, I would gladly walk all the way from here to Santa Rosa for one more glimpse of him!' Locking myself away from secretaries and visitors, I spent the next twenty-four hours in seclusion... His name has now passed into the heritage of common speech. Listing 'burbank' as a transitive verb, Webster's New International Dictionary defines it: 'To cross or graft (a plant). Hence, figuratively, to improve (anything, as a process or institution) by selecting good features and rejecting bad, or by adding good features.' 'Beloved Burbank,' I cried after reading the definition, 'your very name is now a synonym for goodness!

As a task becomes automated, the parts of the brain involved in conscious reasoning become less active and other parts of the brain take over. You could call it the “OK plateau,” the point at which you decide you’re OK with how good you are at something, turn on autopilot, and stop improving.

Whatever the circumstances of a child’s early life, and whatever the history and current state of that child, every human has the built-in power to improve, to change for the better, to significantly restore and often to recover. Tomorrow, that person you see in the mirror can be a stronger, more capable, livelier, more powerfully centered, and still-growing person.

Progress in human affairs, whether in science or in history or in society, has come mainly through the bold readiness of human beings not to confine themselves to seeking piecemeal improvements in the way things are done, but to present fundamental challenges in the name of reason to the current way of doing things and to the avowed or hidden assumptions on which it rests

Unix is not so much a product as it is a painstakingly compiled oral history of the hacker subculture. It is our Gilgamesh epic: a living body of narrative that many people know by heart, and tell over and over again—making their own personal embellishments whenever it strikes their fancy. The bad embellishments are shouted down, the good ones picked up by others, polished, improved, and, over time, incorporated into the story. […] Thus Unix has slowly accreted around a simple kernel and acquired a kind of complexity and asymmetry about it that is organic, like the roots of a tree, or the branchings of a coronary artery. Understanding it is more like anatomy than physics.

Viagra isn't the only drug being prescribed off-label for women with arousal problems. Los Angeles urologist Jennifer Berman told me some doctors are prescribing low doses of Ritalin. Drugs like Ritalin improve a person's focus, so it stands to reason that it would make it easier to stay attuned to subtle changes taking place in one's body. 'It enables a woman to focus o the task at hand,' said Berman, managing, though surely not intending, to make sex sound like homework.

Before you tell me how to do it better, before you lay out your big plans for changing, fixing, and improving me, before you teach me how to pick myself up and dust myself off so that I can be shiny and successful—know this: I’ve heard it before. I’ve been graded, rated, and ranked. Coached, screened, and scored. I’ve been picked first, picked last, and not picked at all. And that was just kindergarten.

The Transhumanist Party aims to motivate and mobilize both female and male scientists and engineers to take on additional responsibilities as rational politicians. It does not mean replacing democracy with technocracy. It means that our government needs help in making the right policies and investing in science, health, and technology for the improvement of the human condition and the long-term survival of the human race.

Maybe it's because we could pass along science. You wrote a fact in a book and there it sat until someone born five hundred years later improved it. Refined it, implemented it more usefully. Easy. You couldn't do that with soul-learning. We all started from zero. From less than zero, actually. We started whiny, without grace. Obsessed only with our own needing. And the dead couldn't teach us anything about that. No facts or tables or proofs. You just had to live and suffer and then teach our kids to do the same.

The decay of belief has come about through the honest doubt, the careful and fearless thinking of highly intelligent men of science and philosophy. Moved by a zeal and reverence for facts, they have tried to see, understand, and face life as it is without wishful thinking. Yet for all that they have done to improve the conditions of life, their picture of the universe seems to leave the individual without ultimate hope. The price of their miracles in this world has been the disappearance of the world-to-come, and one is inclined to ask the old question, “What shall it profit a man if he gain the whole world and lose his soul?” Logic, intelligence, and reason are satisfied, but the heart goes hungry. For the heart has learned to feel that we live for the future. Science may, slowly and uncertainly, give us a better future—for a few years. And then, for each of us, it will end. It will all end. However long postponed, everything composed must decompose.

The theory of universal gravitation is not cast-iron. No theory is, and there is always room for improvement. Isn't that so? Science is constructed out of approximations that gradually approach the truth. . . Well, that means all theories are subject to constant testing and modification, doesn't it? And if it eventually turns out that they're not quite close enough to the truth, they need to be replaced by something that's closer. Right?

The researchers found that nearly every change they made was followed by a temporary uptick in performance, even when it involved simply undoing a previous change. They concluded that the increases in worker productivity were not due to better lighting or better pay or longer breaks per se. They were just temporary improvements caused by a change in routine.

You frequently state, and in your letter you imply, that I have developed a completely one-sided outlook and look at everything in terms of science. Obviously my method of thought and reasoning is influenced by a scientific training – if that were not so my scientific training will have been a waste and a failure. But you look at science (or at least talk of it) as some sort of demoralizing invention of man, something apart from real life, and which must be cautiously guarded and kept separate from everyday existence. But science and everyday life cannot and should not be separated. Science, for me, gives a partial explanation of life. In so far as it goes, it is based on fact, experience and experiment. Your theories are those which you and many other people find easiest and pleasantest to believe, but so far as I can see, they have no foundation other than they leaf to a pleasanter view of life (and an exaggerated idea of our own importance)... I agree that faith is essential to success in life (success of any sort) but I do not accept your definition of faith, i.e. belief in life after death. In my view, all that is necessary for faith is the belief that by doing our best we shall come nearer to success and that success in our aims (the improvement of the lot of mankind, present and future) is worth attaining. Anyone able to believe in all that religion implies obviously must have such faith, but I maintain that faith in this world is perfectly possible without faith in another world… It has just occurred to me that you may raise the question of the creator. A creator of what? ... I see no reason to believe that a creator of protoplasm or primeval matter, if such there be, has any reason to be interested in our significant race in a tiny corner of the universe, and still less in us, as still more significant individuals. Again, I see no reason why the belief that we are insignificant or fortuitous should lessen our faith – as I have defined it.

Moreover, the sciences are monuments devoted to the public good; each citizen owes to them a tribute proportional to his talents. While the great men, carried to the summit of the edifice, draw and put up the higher floors, the ordinary artists scattered in the lower floors, or hidden in the obscurity of the foundations, must only seek to improve what cleverer hands have created.

Biological instincts are the key to understanding how every single human being is wired. The marvelous interplay of various brain circuits creates our instinctual reality of the daily life. If you’re conscious about the fact that there lies a complex yet vividly beautiful brain circuit mechanism behind every single impulse of your daily emotions, then you can choose how to react upon each of those impulses. You can thus program your behavioral response in a certain situation.

New caution.— Let us stop thinking so much about punishing, reproaching, and improving others! We rarely change an individual, and if we should succeed for once, something may also have been accomplished, unnoticed: we may have been changed by him. Let us rather see to it that our own influence on all that is yet to come balances and outweighs his influence. Let us not contend in a direct fight—and that is what all reproaching, punishing, and attempts to improve others amount to. Let us rather raise ourselves that much higher. Let us color our own example ever more brilliantly. Let our brilliance make them look dark. No, let us not become darker ourselves on their account, like ail those who punish others and feel dissatisfied. Let us sooner step aside. Let us look away.46

Thinking scientifically requires the ability to reason abstractly, which itself is at the foundation of all morality. Consider the mental rotation required to implement the Golden Rule: Do unto others as you would have them do unto you. This necessitates one to change positions—to become the other—and then to extrapolate what action X would feel like as the receiver instead of the doer (or as the victim instead of the perpetrator). A case can be made that the type of conceptual ratiocination required for both scientific and moral reasoning not only is linked historically and psychologically, but also that it has been improving over time as we become better at nonconcrete, theoretical reflection.

In truth, neither the narrative of oppression and exploitation nor that of ‘The White Man’s Burden’ completely matches the facts. The European empires did so many different things on such a large scale, that you can find plenty of examples to support whatever you want to say about them. You think that these empires were evil monstrosities that spread death, oppression and injustice around the world? You could easily fill an encyclopedia with their crimes. You want to argue that they in fact improved the conditions of their subjects with new medicines, better economic conditions and greater security? You could fill another encyclopedia with their achievements. Due to their close cooperation with science, these empires wielded so much power and changed the world to such an extent that perhaps they cannot be simply labelled as good or evil. They created the world as we know it, including the ideologies we use in order to judge them.

Today the guns are silent. A great tragedy has ended. A great victory has been won... A new era is upon us. Even the lesson of victory itself brings with it profound concern, both for our future security and the survival of civilization. The destructiveness of the war potential, through progressive advances in scientific discovery, has in fact now reached a point which revises the traditional concepts of war. Men since the beginning of time have sought peace... Military alliances, balances of power, leagues of nations, all in turn have failed, leaving the only path to be by way of the crucible of war. We have had our last chance. If we do not now devise some greater and more equitable system, Armageddon will be at our door. The problem basically is theological and involves a spiritual recrudescence and improvement of human character that will synchronize with our matchless advances in science, art, literature and all material and cultural developments of the past two thousand years. It must be of the spirit if we are to save the flesh.

But the history of science—by far the most successful claim to knowledge accessible to humans—teaches that the most we can hope for is successive improvement in our understanding, learning from our mistakes, an asymptotic approach to the Universe, but with the proviso that absolute certainty will always elude us. We will always be mired in error. The most each generation can hope for is to reduce the error bars a little, and to add to the body of data to which error bars apply. The error bar is a pervasive, visible self-assessment of the reliability of our knowledge.

Yet like many other human traits that made sense in past ages but cause trouble in the modern age, the knowledge illusion has its downside. The world is becoming ever more complex, and people fail to realise just how ignorant they are of what’s going on. Consequently some who know next to nothing about meteorology or biology nevertheless propose policies regarding climate change and genetically modified crops, while others hold extremely strong views about what should be done in Iraq or Ukraine without being able to locate these countries on a map. People rarely appreciate their ignorance, because they lock themselves inside an echo chamber of like-minded friends and self-confirming newsfeeds, where their beliefs are constantly reinforced and seldom challenged. Providing people with more and better information is unlikely to improve matters. Scientists hope to dispel wrong views by better science education, and pundits hope to sway public opinion on issues such as Obamacare or global warming by presenting the public with accurate facts and expert reports. Such hopes are grounded in a misunderstanding of how humans actually think. Most of our views are shaped by communal groupthink rather than individual rationality, and we hold on to these views out of group loyalty. Bombarding people with facts and exposing their individual ignorance is likely to backfire. Most people don’t like too many facts, and they certainly don’t like to feel stupid. Don’t be so sure that you can convince Tea Party supporters of the truth of global warming by presenting them with sheets of statistical data.

While humans have the propensity to develop a suite of prosocial behaviors, they are also capable of developing antisocial behavior, engaging in substance abuse, experiencing depression, and bearing children at an early age...Young people who develop aggressive behavior tendencies are likely to develop problems with tobacco, alcohol, and other drug use; to fail academically; to have children at an early age; and to raise children likely to have the same problems.

Although listening is often more fun, reading improves comprehension and recall. Whereas listening promotes intuitive thinking, reading activates more analytical processing. It’s true in English and Chinese—people display better logical reasoning when the same trivia questions, riddles, and puzzles are written rather than spoken. With print, you naturally slow down at the start of a paragraph to process the core idea and use paragraph breaks and headers to chunk information.

A better-constituted boy would certainly have profited under my intelligent tutors, with their scientific apparatus; and would, doubtless, have found the phenomena of electricity and magnetism as fascinating as I was, every Thursday, assured they were. As it was, I could have paired off, for ignorance of whatever was taught me, with the worst Latin scholar that was ever turned out of a classical academy. I read Plutarch, and Shakespeare, and Don Quixote by the sly, and supplied myself in that way with wandering thoughts, while my tutor was assuring me that "an improved man, as distinguished from an ignorant one, was a man who knew the reason why water ran downhill." I had no desire to be this improved man; I was glad of the running water; I could watch it and listen to it gurgling among the pebbles and bathing the bright green water-plants, by the hour together. I did not want to know why it ran; I had perfect confidence that there were good reasons for what was so very beautiful. ("The Lifted Veil")

It’s like we've been flung back in time," he said. "Here we are in the Stone Age, knowing all these great things after centuries of progress but what can we do to make life easier for the Stone Agers? Can we make a refrigerator? Can we even explain how it works? What is electricity? What is light? We experience these things every day of our lives but what good does it do if we find ourselves hurled back in time and we can’t even tell people the basic principles much less actually make something that would improve conditions. Name one thing you could make. Could you make a simple wooden match that you could strike on a rock to make a flame? We think we’re so great and modern. Moon landings, artificial hearts. But what if you were hurled into a time warp and came face to face with the ancient Greeks. The Greeks invented trigonometry. They did autopsies and dissections. What could you tell an ancient Greek that he couldn’t say, ‘Big Deal.’ Could you tell him about the atom? Atom is a Greek word. The Greeks knew that the major events in the universe can’t be seen by the eye of man. It’s waves, it’s rays, it’s particles." “We’re doing all right.” “We’re sitting in this huge moldy room. It’s like we’re flung back.” “We have heat, we have light.” “These are Stone Age things. They had heat and light. They had fire. They rubbed flints together and made sparks. Could you rub flints together? Would you know a flint if you saw one? If a Stone Ager asked you what a nucleotide is, could you tell him? How do we make carbon paper? What is glass? If you came awake tomorrow in the Middle Ages and there was an epidemic raging, what could you do to stop it, knowing what you know about the progress of medicines and diseases? Here it is practically the twenty-first century and you’ve read hundreds of books and magazines and seen a hundred TV shows about science and medicine. Could you tell those people one little crucial thing that might save a million and a half lives?” “‘Boil your water,’ I’d tell them.” “Sure. What about ‘Wash behind your ears.’ That’s about as good.” “I still think we’re doing fairly well. There was no warning. We have food, we have radios.” “What is a radio? What is the principle of a radio? Go ahead, explain. You’re sitting in the middle of this circle of people. They use pebble tools. They eat grubs. Explain a radio.” “There’s no mystery. Powerful transmitters send signals. They travel through the air, to be picked up by receivers.” “They travel through the air. What, like birds? Why not tell them magic? They travel through the air in magic waves. What is a nucleotide? You don’t know, do you? Yet these are the building blocks of life. What good is knowledge if it just floats in the air? It goes from computer to computer. It changes and grows every second of every day. But nobody actually knows anything.

Effective altruism is about asking "How can I make the biggest difference I can?" and using evidence and careful reasoning to try to find an answer. It takes a scientific approach to doing good. Just as science consists of the honest and impartial attempt to work out what's true, and a committment to believe the truth whatever that turns out to be. As the phrase suggests, effective altruism consists of the honest and impartial attempt to work out what's best for the world, and a commitment to do what's best, whatever that turns out to be.

Was Superstorm Sandy caused by greenhouse warming of the planet? In a word, no. Individual storms arise from specific conditions in the atmosphere. Since records have been kept, hurricanes have varied in number and intensity each season with cycles going up and coming down. The temptation to attribute any specific weather event to global warming distracts us from considering and adopting adaptive strategies, such as improving and expanding irrigation for agriculture and the water supply for cities, that will serve us well when climate changes inevitably arrives on our doorstep.

As to the need of improvement there can be no question whilst the reign of Euclid continues. My own idea of a useful course is to begin with arithmetic, and then not Euclid but algebra. Next, not Euclid, but practical geometry, solid as well as plane; not demonstration, but to make acquaintance. Then not Euclid, but elementary vectors, conjoined with algebra, and applied to geometry. Addition first; then the scalar product. Elementary calculus should go on simultaneously, and come into vector algebraic geometry after a bit. Euclid might be an extra course for learned men, like Homer...

The capital ... shall form a fund, the interest of which shall be distributed annually as prizes to those persons who shall have rendered humanity the best services during the past year. ... One-fifth to the person having made the most important discovery or invention in the science of physics, one-fifth to the person who has made the most eminent discovery or improvement in chemistry, one-fifth to the one having made the most important discovery with regard to physiology or medicine, one-fifth to the person who has produced the most distinguished idealistic work of literature, and one-fifth to the person who has worked the most or best for advancing the fraternization of all nations and for abolishing or diminishing the standing armies as well as for the forming or propagation of committees of peace.

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.

[...] if truth be told, evolution hasn’t yielded many practical or commercial benefits. Yes, bacteria evolve drug resistance, and yes, we must take countermeasures, but beyond that there is not much to say. Evolution cannot help us predict what new vaccines to manufacture because microbes evolve unpredictably. But hasn’t evolution helped guide animal and plant breeding? Not very much. Most improvement in crop plants and animals occurred long before we knew anything about evolution, and came about by people following the genetic principle of ‘like begets like’. Even now, as its practitioners admit, the field of quantitative genetics has been of little value in helping improve varieties. Future advances will almost certainly come from transgenics, which is not based on evolution at all. [review of The Evolving World: Evolution in Everyday Life, Nature 442, 983-984 (31 August 2006)]

 I’m . . . concerned. You appear to be upset. What’s wrong?” His voice gentled and his eyes searched mine. “What’s happened? And what can I do to help?” I crossed my arms because my stupid heart was fluttering again. He caught me off guard. I was not at all prepared for Cletus Winston’s concern. “Nothing. Nothing is wrong. I just wanted to bring y’all muffins. Can’t I bring y’all muffins?” He was scrutinizing me again. “No. Something’s off. Is it Jackson James? Do I need to maim him? Because I will. I could give him leprosy, you know. Armadillos are carriers.” My mouth fell open and a bubble of laughter emerged unchecked. “Cletus Winston, you will do no such thing.” “Sheriff’s deputy or not. Just say the word. It might improve him, actually.” “You are terrible.” I laughed, even though he was terrible, and I felt terrible laughing at such a terrible joke. At least, I hope it’s a joke

A troubling philosophical issue also loomed. He served on a panel that was compiling a study of studies for the National Academies of Sciences. The aim was to show that housing for homeless people improved their health and saved the public money, and yet no studies fully supported those widely held claims, none at least that met the standards of the academics on the committee. Some of Jim’s old allies refused to give up the cost-savings argument. He wrote me privately: “Housing homeless people is mandatory. A human right. But I have long been skeptical of the drive to show that it saves money, because that leaves housing dependent on whether it saves money. Ridiculous. Who would ever say that Mass General exists to save money?

I have not yet been able to stereotype my theological views, and have ceased to expect ever to do so. The idea is preposterous. None but an omniscient mind can continue to maintain a precise identity of views and opinions. Finite minds, unless they are asleep or stultified by prejudice, must advance in knowledge. The discovery of new truth will modify old views and opinions, and there is perhaps no end to this process with finite minds in any world. True Christian consistency does not consist in stereotyping our opinions and views, and in refusing to make any improvement lest we should be guilty of change, but it consists in holding our minds open to receive the rays of truth from every quarter and in changing our views and language and practice as often and as fast, as we can obtain further information. I call this Christian consistency, because this course alone accords with a Christian profession. A Christian profession implies the profession of candour and of a disposition to know and obey all truth. It must follow, that Christian consistency implies continued investigation and change of views and practice corresponding with increasing knowledge. No Christian, therefore, and no theologian should be afraid to change his views, his language, or his practices in conformity with increasing light. The prevalence of such a fear would keep the world, at best, at a perpetual stand-still, on all subjects of science, and consequently all improvements would be precluded.

One last point: If your relationship with your family is especially difficult, working to improve it might sometimes feel like a lost cause. It’s easy to throw up your hands. Almost every day, we hear from people all over the world who feel stuck in family problems that seem like they have no solution. Maybe you have said, “I just want to turn my back on those people and get on with my life.” Giving up is almost always a mistake, because “those people” are, in a mystical way, you. Your spouse is a completion of you as a person. Your kids provide a rare glimpse into your own past. Your parents are a vision of your future. Your siblings are a representation of how others see you. Giving that up means losing insight into yourself, which is a lost opportunity to gain self-knowledge and make progress as a person. Never give up on the relationships that you did not choose, if at all possible. But what about the relationships that you have chosen? These are your friendships, and that’s the next part of our lives to build.

Defining philosophy as “an activity, attempting by means of discussion and reasoning, to make life happy,” he believed that happiness is gained through the achievement of moral self-sufficiency (autarkeia) and freedom from disturbance (ataraxia). The main obstacles to the goal of tranquillity of mind are our unnecessary fears and desires, and the only way to eliminate these is to study natural science. The most serious disturbances of all are fear of death, including fear of punishment after death, and fear of the gods. Scientific inquiry removes fear of death by showing that the mind and spirit are material and mortal, so that they cannot live on after we die: as Epicurus neatly and logically puts it: “Death…is nothing to us: when we exist, death is not present; and when death is present, we do not exist. Consequently it does not concern either the living or the dead, since for the living it is non-existent and the dead no longer exist” (Letter to Menoeceus 125). As for fear of the gods, that disappears when scientific investigation proves that the world was formed by a fortuitous concourse of atoms, that the gods live outside the world and have no inclination or power to intervene in its affairs, and that irregular phenomena such as lightning, thunder, volcanic eruptions, and earthquakes have natural causes and are not manifestations of divine anger. Every Epicurean would have agreed with Katisha in the Mikado when she sings: But to him who’s scientific There’s nothing that’s terrific In the falling of a flight of thunderbolts! So the study of natural science is the necessary means whereby the ethical end is attained. And that is its only justification: Epicurus is not interested in scientific knowledge for its own sake, as is clear from his statement that “if we were not disturbed by our suspicions concerning celestial phenomena, and by our fear that death concerns us, and also by our failure to understand the limits of pains and desires, we should have no need of natural science” (Principal Doctrines 11). Lucretius’ attitude is precisely the same as his master’s: all the scientific information in his poem is presented with the aim of removing the disturbances, especially fear of death and fear of the gods, that prevent the attainment of tranquillity of mind. It is very important for the reader of On the Nature of Things to bear this in mind all the time, particularly since the content of the work is predominantly scientific and no systematic exposition of Epicurean ethics is provided.25 Epicurus despised philosophers who do not make it their business to improve people’s moral condition: “Vain is the word of a philosopher by whom no human suffering is cured. For just as medicine is of no use if it fails to banish the diseases of the body, so philosophy is of no use if it fails to banish the suffering of the mind” (Usener fr. 221). It is evident that he would have condemned the majority of modern philosophers and scientists.

The history of man proves that religion perverts man's concept of life and the universe, and has made him a cringing coward before the blind forces of nature. If you believe that there is a God; that man was 'created'; that he was forbidden to eat of the fruit of the 'tree of knowledge'; that he disobeyed; that he is a 'fallen angel'; that he is paying the penalty for his 'sins,' then you devote your time praying to appease an angry and jealous God. If, on the other hand, you believe that the universe is a great mystery; that man is the product of evolution; that he is born without knowledge; that intelligence comes from experience, then you devote your time and energies to improving his condition with the hope of securing a little happiness here for yourself and your fellow man. That is the difference. If man was 'created,' then someone made a grievous mistake.

Ideology, n. An imaginary relationship to a real situation. In common usage, what the other person has, especially when systematically distorting the facts. But it seems to us that an ideology is a necessary feature of cognition, and if anyone were to lack one, which we doubt, they would be badly disabled. There is a real situation, that can't be denied, but it is too big for any individual to know in full, and so we must create our understanding by way of an act of the imagination. So we all have an ideology, and this is a good thing. So much information pours into the mind, ranging from sensory experience to discursive and mediated inputs of all kinds, that some kind of personal organizing system is necessary to make sense of things in ways that allow one to decide and to act. Worldview, philosophy, religion, these are all synonyms for ideology as defined above; and so is science, although it's a different one, the special one, by way of its perpetual cross-checking with reality tests of all kinds, and its continuous sharpening of focus. That surely makes science central to a most interesting project, which is to invent, improve, and put to use an ideology that explains in a coherent and useful way as much of the blooming buzzing inrush of the world as possible. What one would hope for in an ideology is clarity and explanatory breadth, and power. We leave the proof of this as an exercise for the reader.

Twenty-five hundred years ago it might have been said that man understood himself as well as any other part of his world. Today he is the thing he understands least. Physics and biology have come a long way, but there has been no comparable development of anything like a science of human behavior. Greek physics and biology are now of historical interest only (no modern physicist or biologist would turn to Aristotle for help), but the dialogues of Plato are still assigned to students and cited as if they threw light on human behavior. Aristotle could not have understood a page of modern physics or biology, but Socrates and his friends would have little trouble in following most current discussions of human affairs. And as to technology, we have made immense strides in controlling the physical and biological worlds, but our practices in government, education, and much of economics, though adapted to very different conditions, have not greatly improved. We can scarcely explain this by saying that the Greeks knew all there was to know about human behavior. Certainly they knew more than they knew about the physical world, but it was still not much. Moreover, their way of thinking about human behavior must have had some fatal flaw. Whereas Greek physics and biology, no matter how crude, led eventually to modern science, Greek theories of human behavior led nowhere. If they are with us today, it is not because they possessed some kind of eternal verity, but because they did not contain the seeds of anything better.

All organisms vary. It is in the highest degree improbable that any given variety should have exactly the same relations to surrounding conditions as the parent stock. In that case it is either better fitted (when the variation may be called useful), or worse fitted, to cope with them. If better, it will tend to supplant the parent stock; if worse, it will tend to be extinguished by the parent stock. If (as is hardly conceivable) the new variety is so perfectly adapted to the conditions that no improvement upon it is possible,—it will persist, because, though it does not cease to vary, the varieties will be inferior to itself. If, as is more probable, the new variety is by no means perfectly adapted to its conditions, but only fairly well adapted to them, it will persist, so long as none of the varieties which it throws off are better adapted than itself. On the other hand, as soon as it varies in a useful way, i.e. when the variation is such as to adapt it more perfectly to its conditions, the fresh variety will tend to supplant the former.

The most obvious and the most distinctive features of the History of Civilisation, during the last fifty years, is the wonderful increase of industrial production by the application of machinery, the improvement of old technical processes and the invention of new ones, accompanied by an even more remarkable development of old and new means of locomotion and intercommunication. By this rapid and vast multiplication of the commodities and conveniences of existence, the general standard of comfort has been raised, the ravages of pestilence and famine have been checked, and the natural obstacles, which time and space offer to mutual intercourse, have been reduced in a manner, and to an extent, unknown to former ages. The diminution or removal of local ignorance and prejudice, the creation of common interests among the most widely separated peoples, and the strengthening of the forces of the organisation of the commonwealth against those of political or social anarchy, thus effected, have exerted an influence on the present and future fortunes of mankind the full significance of which may be divined, but cannot, as yet, be estimated at its full value.

From a very early age Edison became used to doing things for himself, by necessity. His family was poor, and by the age of twelve he had to earn money to help his parents. He sold newspapers on trains, and traveling around his native Michigan for his job, he developed an ardent curiosity about everything he saw. He wanted to know how things worked—machines, gadgets, anything with moving parts. With no schools or teachers in his life, he turned to books, particularly anything he could find on science. He began to conduct his own experiments in the basement of his family home, and he taught himself how to take apart and fix any kind of watch. At the age of fifteen he apprenticed as a telegraph operator, then spent years traveling across the country plying his trade. He had no chance for a formal education, and nobody crossed his path who could serve as a teacher or mentor. And so in lieu of that, in every city he spent time in, he frequented the public library. One book that crossed his path played a decisive role in his life: Michael Faraday’s two-volume Experimental Researches in Electricity. This book became for Edison what The Improvement of the Mind had been for Faraday. It gave him a systematic approach to science and a program for how to educate himself in the field that now obsessed him—electricity. He could follow the experiments laid out by the great Master of the field and absorb as well his philosophical approach to science. For the rest of his life, Faraday would remain his role model. Through books, experiments, and practical experience at various jobs, Edison gave himself a rigorous education that lasted about ten years, up until the time he became an inventor. What made this successful was his relentless desire to learn through whatever crossed his path, as well as his self-discipline. He had developed the habit of overcoming his lack of an organized education by sheer determination and persistence. He worked harder than anyone else. Because he was a consummate outsider and his mind had not been indoctrinated in any school of thought, he brought a fresh perspective to every problem he tackled. He turned his lack of formal direction into an advantage. If you are forced onto this path, you must follow Edison’s example by developing extreme self-reliance. Under these circumstances, you become your own teacher and mentor. You push yourself to learn from every possible source. You read more books than those who have a formal education, developing this into a lifelong habit. As much as possible, you try to apply your knowledge in some form of experiment or practice. You find for yourself second-degree mentors in the form of public figures who can serve as role models. Reading and reflecting on their experiences, you can gain some guidance. You try to make their ideas come to life, internalizing their voice. As someone self-taught, you will maintain a pristine vision, completely distilled through your own experiences—giving you a distinctive power and path to mastery.

So let’s consider an alternative diet, say 1200 kcal consisting of 30% protein, 15% carbs (i.e., 180 kcal or 45 grams), and 55% fat. After a week or two of getting adapted (during which you may experience some of the fuel limitation symptoms discussed above), your serum ketones rise up in the range (1-2 millimolar) where they meet at least half of the brain’s fuel supply. Now if you go for that 5 mile run, almost all of your body’s muscle fuel comes from fat, leaving your dietary carb intake plus gluconeogenesis from protein to meet the minor fraction of your brain’s energy need not provided from ketones. And, oh yes, after your run while on the low carb diet, your ketone levels actually go up a bit (not dangerously so), further improving fuel flow to your brain. So what does this mean for the rest of us who are not compulsive runners? Well, this illustrates that the keto-adapted state allows your body more flexibility in meeting its critical organ energy needs than a ‘balanced’ but energy-restricted diet. And in particular, this also means that your brain is a “carbohydrate dependent organ” (as claimed by the USDA Dietary Guidelines Advisory Committee as noted in Chapter 3) ONLY when you are eating a high carbohydrate diet. When carbohydrate is restricted as in the example above, your body’s appropriate production of ketones frees the brain from this supposed state of ‘carbohydrate dependency’. And because exercise stimulates ketone production, your brain’s fuel supply is better supported during and after intense exercise when on a low carbohydrate diet than when your carbohydrate intake is high (see below).

In the first case it emerges that the evidence that might refute a theory can often be unearthed only with the help of an incompatible alternative: the advice (which goes back to Newton and which is still popular today) to use alternatives only when refutations have already discredited the orthodox theory puts the cart before the horse. Also, some of the most important formal properties of a theory are found by contrast, and not by analysis. A scientist who wishes to maximize the empirical content of the views he holds and who wants to understand them as clearly as he possibly can must therefore introduce other views; that is, he must adopt a pluralistic methodology. He must compare ideas with other ideas rather than with 'experience' and he must try to improve rather than discard the views that have failed in the competition. Proceeding in this way he will retain the theories of man and cosmos that are found in Genesis, or in the Pimander, he will elaborate them and use them to measure the success of evolution and other 'modern' views. He may then discover that the theory of evolution is not as good as is generally assumed and that it must be supplemented, or entirely replaced, by an improved version of Genesis. Knowledge so conceived is not a series of self-consistent theories that converges towards an ideal view; it is not a gradual approach to truth. It is rather an ever increasing ocean of mutually incompatible alternatives, each single theory, each fairy-tale, each myth that is part of the collection forcing the others in greater articulation and all of them contributing, via this process of competition, to the development of our consciousness. Nothing is ever settled, no view can ever be omitted from a comprehensive account. Plutarch or Diogenes Laertius, and not Dirac or von Neumann, are the models for presenting a knowledge of this kind in which the history of a science becomes an inseparable part of the science itself - it is essential for its further development as well as for giving content to the theories it contains at any particular moment. Experts and laymen, professionals and dilettani, truth-freaks and liars - they all are invited to participate in the contest and to make their contribution to the enrichment of our culture. The task of the scientist, however, is no longer 'to search for the truth', or 'to praise god', or 'to synthesize observations', or 'to improve predictions'. These are but side effects of an activity to which his attention is now mainly directed and which is 'to make the weaker case the stronger' as the sophists said, and thereby to sustain the motion of the whole.

It is a fact of life on our beleaguered little planet that widespread torture, famine and governmental criminal irresponsibility are much more likely to be found in tyrannical than in democratic governments. Why? Because the rulers of the former are much less likely to be thrown out of office for their misdeeds than the rulers of the latter. This is error-correcting machinery in politics. The methods of science, with all its imperfections, can be used to improve social, political and economic systems, and this is, I think, true no matter what criterion of improvement is adopted. How is this possible if science is based on experiment? Humans are not electrons or laboratory rats. But every act of Congress, every Supreme Court decision, every Presidential National Security Directive, every change in the Prime Rate is an experiment. Every shift in economic policy, every increase or decrease in funding for Head Start, every toughening of criminal sentences is an experiment. Exchanging needles, making condoms freely available, or decriminalizing marijuana are all experiments. Doing nothing to help Abyssinia against Italy, or to prevent Nazi Germany from invading the Rhineland was an experiment. Communism in Eastern Europe, the Soviet Union and China was an experiment. Privatizing mental health care or prisons is an experiment. Japan and West Germany investing a great deal in science and technology and next to nothing on defense - and finding that their economies boomed - was an experiment. Handguns are available for self-protection in Seattle, but not in nearby Vancouver, Canada; handgun killings are five times more common in Seattle and the handgun suicide rate is ten times greater in Seattle. Guns make impulsive killing easy. This is also an experiment. In almost all of these cases, adequate control experiments are not performed, or variables are insufficiently separated. Nevertheless, to a certain and often useful degree, such ideas can be tested. The great waste would be to ignore the results of social experiments because they seem to be ideologically unpalatable.

The intelligent want self-control; children want candy. —RUMI INTRODUCTION Welcome to Willpower 101 Whenever I mention that I teach a course on willpower, the nearly universal response is, “Oh, that’s what I need.” Now more than ever, people realize that willpower—the ability to control their attention, emotions, and desires—influences their physical health, financial security, relationships, and professional success. We all know this. We know we’re supposed to be in control of every aspect of our lives, from what we eat to what we do, say, and buy. And yet, most people feel like willpower failures—in control one moment but overwhelmed and out of control the next. According to the American Psychological Association, Americans name lack of willpower as the number-one reason they struggle to meet their goals. Many feel guilty about letting themselves and others down. Others feel at the mercy of their thoughts, emotions, and cravings, their lives dictated by impulses rather than conscious choices. Even the best-controlled feel a kind of exhaustion at keeping it all together and wonder if life is supposed to be such a struggle. As a health psychologist and educator for the Stanford School of Medicine’s Health Improvement Program, my job is to help people manage stress and make healthy choices. After years of watching people struggle to change their thoughts, emotions, bodies, and habits, I realized that much of what people believed about willpower was sabotaging their success and creating unnecessary stress. Although scientific research had much to say that could help them, it was clear that these insights had not yet become part of public understanding. Instead, people continued to rely on worn-out strategies for self-control. I saw again and again that the strategies most people use weren’t just ineffective—they actually backfired, leading to self-sabotage and losing control. This led me to create “The Science of Willpower,” a class offered to the public through Stanford University’s Continuing Studies program. The course brings together the newest insights about self-control from psychology, economics, neuroscience, and medicine to explain how we can break old habits and create healthy habits, conquer procrastination, find our focus, and manage stress. It illuminates why we give in to temptation and how we can find the strength to resist. It demonstrates the importance of understanding the limits of self-control,
