The story of our most fundamental human right - and why it is in grave danger. Without a moment's pause, we share our most intimate thoughts with trillion-dollar tech companies. Their algorithms categorize us and jump to conclusions about who we are. They even shape our everyday thoughts and actions - from who we date to how we vote. But this is just the latest front in an age-old struggle. Part history and part manifesto, Freedom to Think charts the history and importance of our most basic human right: freedom of thought. From Galileo to Nudge Theory to Alexa, human rights lawyer Susie Alegre explores how the powerful have always sought to get inside our heads, influence how we think and shape what we buy. Providing a bold new framework to understand how our agency is being gradually undermined, Freedom to Think is a groundbreaking and vital charter for taking back our humanity and safeguarding our reason. 'Profoundly essential and deeply engaging.' - Shoshana Zuboff, author of The Age of Surveillance Capitalism 'Engaging and entertaining. A call to action on one of the most pressing issues of our time.' - Jennifer Robinson, leading human rights lawyer
