When a chatbot lies about an airline's bereavement policy, who is to blame? When an AI-generated painting wins a state art competition, what does it mean to be a creator? Our relationship with artificial intelligence is not just technical; it's profoundly human. Smarter Together is your essential guide to the hidden psychology behind the AI revolution. Drawing on insights from neuroscience, behavioral science, and their popular NYU courses, the authors reveal how intelligent systems are designed to mirror our thinking, feeling, and decision-making. Through unforgettable case studies, this book unpacks the new equations of trust, the cognitive biases that shape our choices, and the cultural forces defining AI's promise and challenge. Moving from theory to practice, it provides a vital toolkit for designing and marketing AI products that augment, rather than replace, human intelligence.
