Speak Data

The first pop nonfiction book to explore the definition of data and how we can learn to speak that language features thought-provoking conversations with 17 extraordinary leaders in business, tech, medicine, psychology, health, art, and more who share new ideas about data, unpacking its powerful ability to reveal patterns, tell stories, stir emotion, and illuminate complexity. Data may be the most powerful force in society today. Data is everywhere, present in every moment, every event, every transaction, or interaction with someone else. Every time you send a text, call a friend, fill out a form, hail a taxi, stream a movie, surf the web, pay a bill, buy groceries, buy anything, take your temperature, count your steps, swipe right (or left), you generate data. There's data in the weather, in the air, in the ground, in outer space. If you own a smartwatch, you carry data on your body. If you have a cardiac pacemaker, you carry data in your body. So, what is data, really? It's a question that is surprisingly hard to answer. To some, data means numbers: figures on a screen, dots on a graph. It's also often (falsely) equated with facts, an invariable form of concrete knowledge that always tells the truth. But in reality, data is hardly so incontrovertible. Data is an abstraction of reality, a useful but imperfect representation of real life. Like life, it's full of nuance, imprecision, and ambivalence. It's quantitative and it's qualitative. And it's made by us—humans. These are some of the ideas that information designers Giorgia Lupi and Phillip Cox explore in their fascinating new book Speak Data: Artists, Scientists, Thinkers, and Dreamers on How We Live Our Lives in Numbers. Speak Data invites us to see data differently—not just as numbers on a chart, but as a way to understand and communicate who we are, how we connect, and how we make sense of the world. It's grounded in the principles of Data Humanism, a concept developed by coauthor and award-winning information designer Giorgia Lupi, which centers on people, rather than numbers, in its conception of data. In this beautifully illustrated book, the authors present data as a vocabulary that anyone can use, showing that when we truly learn to "speak data," we can open up new worlds of meaning about ourselves and everything around us. Interviews in Speak Data include: Tech pioneer John Maeda on the value of data visualization during global emergencies. Marketing legend Seth Godin on how to use data to get people to really care about climate change. Museum curator Paola Antonelli on whether data is art.

Neuroscientist and physical therapist David Putrino on how tracking long Covid has taught him to think differently about patient data versus patient experience. Physician and design researcher Bon Ku on how data revealed a better way to design hospital emergency departments.
