Companies used to rely on human experts and their years of experience to guide them. Now, cutting-edge organizations are mining the data and crunching numbers instead, to come up with more accurate, less biased predictions. As Freakonomics detailed, statistical analysis can reveal the secret levers of causation. But economist Ian Ayres argues that that's only part of the story - super crunching is revolutionizing the way we all make decisions. Beginning with examples of the mathematician who out-predicted wine buffs in determining the best vintages, and the sports scouts who now use statistics rather than intuition to pick winners, Super Crunchers exposes the world of data-miners, introducing the people and the techniques. It illuminates the hidden patterns all around us. No businessperson, academic, student, or consumer (statistically that's everyone) should make another move without getting to grips with thinking-by-numbers - the new way to be smart, savvy and statistically superior.

The part-owner of StickK.com uses research into incentives and punishments to introduce the concept of "commitment contracts," an easy strategy for setting and achieving goals that is already in use by successful companies and individuals across America. Ayres shares engaging, often astounding, real-life stories that show the carrot-and-stick principle in action, from the compulsive sneezer who needed a "stick" (the potential loss of $50 per week to a charity he didn't like) to those who need a carrot with their stick (the New York Times columnist who quit smoking by pledging a friend $5,000 per smoke . . . if she would do the same for him). You'l learn why you might want to hire a "professional nagger" whom you'll do anything to avoid- no, your spouse won't do!- and how you can "hand-tie" your future self to accomplish what you want done now. You'll find out how a New Zealand ad exec successfully "sold his smoking addiction", and why Zappos offered new employees $2,000 to quit cigarettes.

A riveting exploration of the most difficult and important part of what doctors do, by Yale School of Medicine physician Dr. Lisa Sanders, author of the monthly New York Times Magazine column "Diagnosis," the inspiration for the hit Fox TV series House, M.D. "The experience of being ill can be like waking up in a foreign country. Life, as you formerly knew it, is on hold while you travel through this other world as unknown as it is unexpected. When I see patients in the hospital or in my office who are suddenly, surprisingly ill, what they really want to know is, ‘What is wrong with me?’ They want a road map that will help them manage their new surroundings. The ability to give this unnerving and unfamiliar place a name, to know it–on some level–restores a measure of control, independent of whether or not that diagnosis comes attached to a cure. Because, even today, a diagnosis is frequently all a good doctor has to offer." A healthy young man suddenly loses his memory–making him unable to remember the events of each passing hour. Two patients diagnosed with Lyme disease improve after antibiotic treatment–only to have their symptoms mysteriously return. A young woman lies dying in the ICU–bleeding, jaundiced, incoherent–and none of her doctors know what is killing her. In Every Patient Tells a Story, Dr. Lisa Sanders takes us bedside to witness the process of solving these and other diagnostic dilemmas, providing a firsthand account of the expertise and intuition that lead a doctor to make the right diagnosis. Never in human history have doctors had the knowledge, the tools, and the skills that they have today to diagnose illness and disease. And yet mistakes are made, diagnoses missed, symptoms or tests misunderstood. In this high-tech world of modern medicine, Sanders shows us that knowledge, while essential, is not sufficient to unravel the complexities of illness. She presents an unflinching look inside the detective story that marks nearly every illness–the diagnosis–revealing the combination of uncertainty and intrigue that doctors face when confronting patients who are sick or dying. Through dramatic stories of patients with baffling symptoms, Sanders portrays the absolute necessity and surprising difficulties of getting the patient’s story, the challenges of the physical exam, the pitfalls of doctor-to-doctor communication, the vagaries of tests, and the near calamity of diagnostic errors. In Every Patient Tells a Story, Dr. Sanders chronicles the real-life drama of doctors solving these difficult medical mysteries that not only illustrate the art and science of diagnosis, but often save the patients’ lives.

You're sitting in a windowless conference room. Twenty minutes into the meeting the presenter finally makes it to slide four of a thirty two- slide deck. At least you can read this one, unlike the others, which were crammed with numbers, graphs and charts. You look around, wondering if anyone else is following the presentation. Just about everyone these days suffers from information overload the 24/7 explosion from our computers, smartphones, media, colleagues, and customers. Information is essential to making intelligent decisions, but more often than not, it simply overwhelms us. It's like trying to drink from a fire hose. The question isn't how to stop all those e-mails, meetings, conference calls, and fat reports; that's impossible. The question is what to do with them. How do you find the truly essential nuggets of information and use them with confidence? The solution proposed by Christopher Frank and Paul Magnone sounds deceptively simple: Learn how to ask the right questions at the right time. Whatever field you're in, asking smarter questions will expose you to new information, point you to connections between seemingly unrelated facts, and open new avenues of discussion with your colleagues. The authors explain the seven questions that can help you bring a big- picture perspective to problems that often leave others buried in irrelevant details. And they show through real-life case studies- including Trader Joe's, Starbucks, Kodak, Microsoft, iRobot, and IBM-how their method can have a dramatic impact. It really is possible to convert the fire hose of information into useful insights. Consider a nonbusiness example: the 2010 Icelandic volcano eruption that sent a giant ash cloud toward Europe. Tens of thousands of flights were canceled and five million passengers stranded, leading to billions in economic losses. Europe's best scientists generated oceans of data and carefully modeled the cloud's dispersion pattern. But no one could answer the essential question: Was the concentration of volcanic ash in the air enough to damage a jet engine? Without that key answer, all the carefully gathered facts were useless to the decision makers. Once you adopt the seven questions, you'll start having more productive brainstorming sessions. You'll answer critical questions faster and find unexpected solutions to important problems. And you'll get better at communicating to your colleagues with more clarity and focus, turning down the fire hose that other people have to cope with.

Applied econometrics, known to aficionados as 'metrics, is the original data science. 'Metrics encompasses the statistical methods economists use to untangle cause and effect in human affairs. Through accessible discussion and with a dose of kung fu–themed humor, Mastering 'Metrics presents the essential tools of econometric research and demonstrates why econometrics is exciting and useful. The five most valuable econometric methods, or what the authors call the Furious Five--random assignment, regression, instrumental variables, regression discontinuity designs, and differences in differences--are illustrated through well-crafted real-world examples (vetted for awesomeness by Kung Fu Panda's Jade Palace). Does health insurance make you healthier? Randomized experiments provide answers. Are expensive private colleges and selective public high schools better than more pedestrian institutions? Regression analysis and a regression discontinuity design reveal the surprising truth. When private banks teeter, and depositors take their money and run, should central banks step in to save them? Differences-in-differences analysis of a Depression-era banking crisis offers a response. Could arresting O. J. Simpson have saved his ex-wife's life? Instrumental variables methods instruct law enforcement authorities in how best to respond to domestic abuse. Wielding econometric tools with skill and confidence, Mastering 'Metrics uses data and statistics to illuminate the path from cause to effect. Shows why econometrics is important Explains econometric research through humorous and accessible discussion Outlines empirical methods central to modern econometric practice Works through interesting and relevant real-world examples
