Book Description
Avoid data blunders and create truly useful visualizations Avoiding Data Pitfalls is a reputation-saving handbook for those who work with data, designed to help you avoid the all-too-common blunders that occur in data analysis, visualization, and presentation. Plenty of data tools exist, along with plenty of books that tell you how to use them—but unless you truly understand how to work with data, each of these tools can ultimately mislead and cause costly mistakes. This book walks you step by step through the full data visualization process, from calculation and analysis through accurate, useful presentation. Common blunders are explored in depth to show you how they arise, how they have become so common, and how you can avoid them from the outset. Then and only then can you take advantage of the wealth of tools that are out there—in the hands of someone who knows what they're doing, the right tools can cut down on the time, labor, and myriad decisions that go into each and every data presentation. Workers in almost every industry are now commonly expected to effectively analyze and present data, even with little or no formal training. There are many pitfalls—some might say chasms—in the process, and no one wants to be the source of a data error that costs money or even lives. This book provides a full walk-through of the process to help you ensure a truly useful result. Delve into the "data-reality gap" that grows with our dependence on data Learn how the right tools can streamline the visualization process Avoid common mistakes in data analysis, visualization, and presentation Create and present clear, accurate, effective data visualizations To err is human, but in today's data-driven world, the stakes can be high and the mistakes costly.

Book Description
Equal parts mail art, data visualization, and affectionate correspondence, Dear Data celebrates "the infinitesimal, incomplete, imperfect, yet exquisitely human details of life," in the words of Maria Popova (Brain Pickings), who introduces this charming and graphically powerful book. For one year, Giorgia Lupi, an Italian living in New York, and Stefanie Posavec, an American in London, mapped the particulars of their daily lives as a series of hand-drawn postcards they exchanged via mail weekly—small portraits as full of emotion as they are data, both mundane and magical. Dear Data reproduces in pinpoint detail the full year's set of cards, front and back, providing a remarkable portrait of two artists connected by their attention to the details of their lives—including complaints, distractions, phone addictions, physical contact, and desires. These details illuminate the lives of two remarkable young women and also inspire us to map our own lives, including specific suggestions on what data to draw and how. A captivating and unique book for designers, artists, correspondents, friends, and lovers everywhere.

Book Description
The charges of white privilege and systemic racism that are tearing the country apart fIoat free of reality. Two known facts, long since documented beyond reasonable doubt, need to be brought into the open and incorporated into the way we think about public policy: American whites, blacks, Hispanics, and Asians have different violent crime rates and different means and distributions of cognitive ability. The allegations of racism in policing, college admissions, segregation in housing, and hiring and promotions in the workplace ignore the ways in which the problems that prompt the allegations of systemic racism are driven by these two realities. What good can come of bringing them into the open? America’s most precious ideal is what used to be known as the American Creed: People are not to be judged by where they came from, what social class they come from, or by race, color, or creed. They must be judged as individuals. The prevailing Progressive ideology repudiates that ideal, demanding instead that the state should judge people by their race, social origins, religion, sex, and sexual orientation. We on the center left and center right who are the American Creed’s natural defenders have painted ourselves into a corner. We have been unwilling to say openly that different groups have significant group differences. Since we have not been willing to say that, we have been left defenseless against the claims that racism is to blame. What else could it be? We have been afraid to answer. We must. Facing Reality is a step in that direction.

Book Description
Fake news posts and Twitter trolls were just the beginning. What will happen when misinformation moves from our social media feeds into our everyday lives? Online disinformation stormed our political process in 2016 and has only worsened since. Yet as Samuel Woolley shows in this urgent book, it may pale in comparison to what's to come: humanlike automated voice systems, machine learning, "deepfake" AI-edited videos and images, interactive memes, virtual reality, and more. These technologies have the power not just to manipulate our politics, but to make us doubt our eyes and ears and even feelings. Deeply researched and compellingly written, The Reality Game describes the profound impact these technologies will have on our lives. Each new invention built without regard for its consequences edges us further into this digital dystopia. Yet Woolley does not despair. Instead, he argues pointedly for a new culture of innovation, one built around accountability and especially transparency. With social media dragging us into a never-ending culture war, we must learn to stop fighting and instead prevent future manipulation. This book shows how we can use our new tools not to control people but to empower them.

Book Description
How data science and the analysis of networks help us solve the puzzle of unintended consequences. Social life is full of paradoxes. Our intentional actions often trigger outcomes that we did not intend or even envision. How do we explain those unintended effects and what can we do to regulate them? In Decoding the Social World, Sandra González-Bailón explains how data science and digital traces help us solve the puzzle of unintended consequences—offering the solution to a social paradox that has intrigued thinkers for centuries. Communication has always been the force that makes a collection of people more than the sum of individuals, but only now can we explain why: digital technologies have made it possible to parse the information we generate by being social in new, imaginative ways. And yet we must look at that data, González-Bailón argues, through the lens of theories that capture the nature of social life. The technologies we use, in the end, are also a manifestation of the social world we inhabit. González-Bailón discusses how the unpredictability of social life relates to communication networks, social influence, and the unintended effects that derive from individual decisions. She describes how communication generates social dynamics in aggregate (leading to episodes of “collective effervescence”) and discusses the mechanisms that underlie large-scale diffusion, when information and behavior spread “like wildfire.” She applies the theory of networks to illuminate why collective outcomes can differ drastically even when they arise from the same individual actions. By opening the black box of unintended effects, González-Bailón identifies strategies for social intervention and discusses the policy implications—and how data science and evidence-based research embolden critical thinking in a world that is constantly changing.
