In an era of terrifying unpredictability, we race to address complex crises with neat algorithms, bullet points, or hurried tweets. How could we find the clarity and vision so urgently needed today by being unsure? Uncertain is about the unsung triumph of doing just that. A scientific adventure tale set on the front lines of a volatile era, this paradigm-shifting book by award-winning author Maggie Jackson shows us how to skillfully confront the unexpected and the unknown, and how to harness not-knowing in the service of wisdom, invention, mutual understanding, and even resilience. Long neglected as a topic of study, the newly discovered gifts of uncertainty now fascinate the greatest cognitive scientists – and offer a remarkable antidote to the narrow-mindedness of our day. In laboratories, operating rooms, boardrooms, and on the frontiers of Artificial Intelligence, Uncertain unlocks the secrets to a state of mind that is critical to human achievement yet treated as a shameful flaw.
