In 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, George Washington University professor and psychiatrist Daniel Z. Lieberman, MD, and Georgetown University lecturer Michael E. Long present a potentially life-changing proposal: Much of human life has an unconsidered component that explains an array of behaviors previously thought to be unrelated, including why winners cheat, why geniuses often suffer with mental illness, why nearly all diets fail, and more.

Dopamine, “the molecule of more,” is the chemical in our brains that drives us to seek out newer and better things—the latest gadget, the coolest job, the perfect partner. But for many of us, it’s easy to get stuck in a cycle of never being truly satisfied. Because dopamine can only promise happiness. It can never deliver. That part is up to us.

A dopamina é o neurotransmissor que garantiu a sobrevivência dos nossos antepassados e que, ainda hoje, continua determinando a maioria dos nossos comportamentos. Graças a ela fomos à Lua, encontramos a cura de várias doenças e nos esforçamos para transformar o mundo em um lugar melhor. Mas ela também nos torna suscetíveis a arriscar nosso casamento por uma aventura passageira e é capaz de explicar por que o dependente químico está disposto a fazer qualquer coisa pela próxima dose.

Warum wollen wir wie besessen bestimmte Dinge haben, sind aber gelangweilt, wenn wir sie bekommen? Warum verwandelt sich die Leidenschaft von Verliebten so schnell in Desinteresse? Die Antwort liegt in einem Hormon in unserem Gehirn: Dopamin. Es ist die Quelle unseres Verlangens und lässt uns für einen kurzen Nervenkitzel alles riskieren. Dabei ist es die Aussicht auf etwas Neues, die uns antreibt, nicht die Erfüllung. Dopamin ist der Grund, warum wir forschen und entdecken, aber auch der Ursprung von Verschwendung, Risiko und Sucht.
