Discover why dopamine - the molecule that drives love, creativity, and addiction - might determine humanity's fate. Praised by neuroscientist David Eagleman as "an epic saga you can't put down," this bestseller reveals why we crave what we don't have and how it shapes everything.
Daniel Z. Lieberman, MD, and Michael E. Long are the acclaimed authors of The Molecule of More: How a Single Chemical in Your Brain Drives Love, Sex, and Creativity—and Will Determine the Fate of the Human Race, a groundbreaking exploration of neuroscience and human behavior.
Lieberman is a professor and vice chair of psychiatry at George Washington University. He brings clinical expertise as a Distinguished Fellow of the American Psychiatric Association and has over 50 peer-reviewed publications. Long, a physicist-turned-award-winning writer and Georgetown University lecturer, contributes a unique interdisciplinary perspective.
Their collaboration merges cutting-edge research with accessible storytelling to unravel dopamine’s role in ambition, addiction, and innovation. The book became a #1 bestseller in medicine/science categories and has been praised for transforming complex neurochemistry into a riveting narrative. Lieberman regularly shares insights on platforms like CNN and PBS, while Long’s background in science communication ensures clarity for general audiences.
Their follow-up, Taming the Molecule of More (2024), expands on managing dopamine-driven behaviors. The original work has been endorsed by academics and creatives alike, cementing its status as a modern classic in behavioral psychology.
The Molecule of More explores dopamine’s role as the "chemical of desire," driving human behavior in love, creativity, politics, and addiction. Authors Daniel Z. Lieberman and Michael E. Long argue dopamine fuels our pursuit of novelty and future goals, explaining why we crave success, risk relationships for new thrills, and struggle with diets.
This book suits readers interested in neuroscience, psychology, or self-improvement. It’s ideal for those seeking insights into motivation, addiction, or why happiness fades after achieving goals. Professionals in leadership, therapy, or education will find practical applications for managing dopamine-driven behaviors.
Yes. The book translates complex neuroscience into accessible insights, linking dopamine to everyday struggles like impulsive decisions or career burnout. Its blend of science and real-world examples helps readers harness dopamine for productivity while avoiding its pitfalls.
Key concepts include:
Dopamine fuels initial attraction and passion, but as relationships stabilize, the brain relies on present-focused chemicals like serotonin. This shift explains why long-term partnerships require effort to maintain excitement once the "honeymoon phase" ends.
Dopamine prioritizes future rewards (e.g., career goals, new relationships), while "Here and Now" (H&N) molecules like endorphins focus on present satisfaction (e.g., enjoying a meal or peaceful moment). Balancing both systems is key to well-being.
Winning triggers dopamine surges, creating addiction to the thrill of success. Like drug users chasing a high, winners cheat to replicate that rush, even when it risks their reputation or relationships.
The book cites studies showing liberals and conservatives have different dopamine-driven risk tolerances. Liberals often seek novel solutions (high dopamine), while conservatives prefer tradition (lower dopamine), influencing policy preferences.
Strategies include:
Dopamine’s craving for novelty makes addiction logical to the brain: substances or behaviors offering instant, intense rewards become irresistible despite long-term harm. Recovery requires strengthening H&N systems to appreciate present stability.
Some argue the book oversimplifies complex neurochemistry by attributing diverse behaviors to a single molecule. Critics note environmental and social factors also shape actions, which dopamine alone can’t explain.
The "molecule of more" metaphor illustrates dopamine’s insatiable nature—always seeking newer, better experiences. Anticipation is portrayed as a "thrill of the hunt," while possession is a "boredom trap," urging readers to balance ambition with contentment.

Why do we check our phones compulsively, even when we know nothing important awaits? Why does the thrill of a new relationship inevitably fade? Why do billionaires keep chasing more money they'll never spend? The answer lies in a single molecule that shapes nearly every aspect of human behavior-from the love affairs that define us to the political beliefs that divide us. Dopamine isn't just another brain chemical. It's the neurological force that makes us human, driving us to explore, create, innovate, and conquer. But it comes with a hidden cost: we're biologically designed never to be satisfied. Understanding this molecule reveals why we behave the way we do and offers a path toward genuine happiness in a world engineered to keep us wanting more.
