By: Daniel Z. Lieberman


In ‘The Molecule of More,’ author Daniel Z. Lieberman delves into the fascinating power of dopamine, a single molecule in our brain that shapes our desires, motivations, and distinct aspects of our personalities. This book explores the varied roles dopamine plays in our lives, from how it drives our love life to its impact on our political beliefs and propensity to take risks. It also provides insights into how dopamine affects our creativity and our quest for more. As you read this book summary, expect to discover the ways in which dopamine influences our emotions, behaviors, and how it affects the human race as a whole.

The Power of Dopamine

Dopamine, often referred to as the pleasure molecule, is more than just a feel-good chemical. It’s the molecule of possibilities that gets released when we encounter something new, unexpected, and exciting. The rush we get from making a reward prediction error triggers the highest level of dopamine release and pleasure. Its evolutionary purpose is to motivate us to pursue the things that fall into the “far” category and encourage us to chase our dreams.

The Science Behind Love

Love is more than just a feeling; it also involves complex brain chemistry. At the beginning of a romantic relationship, dopamine, the “feel good” chemical, floods our brains, creating the intense feeling of love. However, this chemical rush only lasts for a short time, leading many couples to experience a bump in the road. Some may turn to infidelity or jump to a new partner, seeking a new dopamine rush. But those who work on establishing a solid relationship can move forward to the next stage of love: companionate love. This type of love relies on the “here and now” chemicals, such as oxytocin, which create a lasting feeling of satisfaction. Understanding these chemical processes helps us to appreciate the different stages of love and build long-lasting, fulfilling relationships.

The Dopamine Addiction

Our brains have two different systems for desire and enjoyment – our dopamine system being responsible for the former. Addictive drugs hijack this system and overwhelm it, causing devastating consequences. Narcs don’t actually get addicted to the chemical high of a specific drug; rather, they crave the dopamine high that it releases, and seek it out by any means necessary. Our brains remember every little detail of our dopamine highs, contributing to addiction. The close association between the desire circuit and the memory system in our brains makes it exceedingly difficult to wean ourselves off the addiction.

Controlling Our Desires

Our brain uses dopamine to make us crave things, but we also have a dopamine control circuit that keeps our desires in check. This system, located in the frontal lobes, enables us to plan and strategize for the future. Research shows that dopamine plays a crucial role in motivating us to get what we want, but excessive control dopamine can prevent us from enjoying our accomplishments. Some people struggle with suppressing their urges and distractions due to a less active dopamine control system, while others tend to be intellectual and ambitious. The next part will delve into the perks and perils of excessive dopamine.

The Creative Power of Dopamine

Dopamine is a neurotransmitter responsible for forming connections in the brain that allow us to plan, imagine, and strategize. This chemical plays a significant role in creativity, as it allows for unconventional thinking and the ability to make unique connections. However, it also has a dark side, as excessive dopamine activity can lead to hallucinations, delusions, and mania, often found in individuals with schizophrenia and bipolar disorder. The link between creativity and mental illness lies in dopamine, as too much of it can produce salience, making seemingly random things appear crucial. Despite this, dopamine’s creative power is apparent, as creatives tend to have brains rich in dopamine, allowing them to think outside the box and come up with innovative ideas.
