Every day of our lives, we make judgments–and we don’t always do a very good job of it. Thinking 101 is an invaluable resource to anyone who wants to think better. In remarkably clear language, and with engaging and often funny examples, Woo-Kyoung Ahn uses cutting-edge research to explain the mistakes we often make–and how to avoid them. –Gretchen Rubin, #1 New York Times bestselling author of The Happiness Project and The Four Tendencies

Thinking 101 is a must-read–a smart and compellingly readable guide to cutting-edge research into how people think. Building from her popular Yale course, Professor Woo-kyoung Ahn shows how a better understanding of how our minds work can help us become smarter and wiser–and even kinder. –Paul Bloom, Professor of Psychology, University of Toronto, Brooks and Suzanne Professor Emeritus of Psychology at Yale University, and the author of The Sweet Spot

Psychologist Woo-kyoung Ahn explains why our judgement is so often wrong–and offers strategies to help us respond to the challenges we all face as individuals and in society at large.

What can K-pop dance moves teach us about how we can best learn new skills? How can a winning soccer goal illustrate the challenge of assigning credit or blame? Why should we think about the way we shop for holiday gifts before starting a new project?

Professor Woo-kyoung Ahn devised a course at Yale called Thinking to help students examine the biases that cause so many problems in their daily lives. It quickly became one of the college’s most popular courses. Now, for the first time, she presents key insights from her years of teaching and research in a book for everyone.

Ahn shows how ‘thinking problems’ stand behind a wide-range of challenges from common, self-inflicted daily aggravations to our most pressing societal issues and inequities. Throughout, Ahn draws on decades of research from other cognitive psychologists, as well as from her own ground-breaking studies. And she presents it all in a compellingly readable style using fun examples from pop culture, anecdotes from her own life, and illuminating stories from history and the headlines.

Thinking 101 is a book that goes far beyond other books on thinking, showing how we can improve not just our own daily lives through better awareness of our biases, but the lives of everyone around us. It is, quite simply, required reading for everyone who wants to think–and live–better.
