The Molecule of More

The book's foundational correction, and the one piece of neuroscience most worth knowing. Dopamine is not the pleasure chemical of popular description; it is centrally involved in anticipation, prediction error and the pursuit of reward.

The dissociation is well established: animals with dopamine disrupted still show pleasure responses to a reward but stop working to obtain it. Wanting and liking are separable systems.

Dopamine is not what pleasure feels like. It is what wanting feels like, and the two are separable.

Their organising metaphor: dopamine handles what is distant in space or time — the future, the possible, the not-yet-possessed. A separate set of here-and-now neurotransmitters handles present experience.

The framework explains the common experience of achieving something and feeling flat immediately afterwards. The circuit that produced the pursuit has nothing to do once the thing is obtained, and it is the louder circuit.

The mechanism underneath: dopamine responds most strongly not to reward but to reward that was better than expected, and drops below baseline when reward is worse than expected.

This explains habituation, why the second time is never like the first, and why variable rewards are so much more compelling than reliable ones — the prediction error is what the system is actually tracking.

Their account follows directly: addiction is a disorder of wanting rather than of liking, which is why people continue pursuing substances and behaviours they no longer enjoy.

This reframing has genuine clinical support and is the book's most practically consequential section — it makes the common observation that an addicted person "doesn't even seem to enjoy it" a prediction of the model rather than a puzzle.

Their application to relationships: early passionate attachment is dopamine territory — anticipation, idealisation, pursuit — and the transition to companionate love is a handover to here-and-now chemistry.

The framework is plausible and the treatment is more speculative than the addiction material. It reads as a reasonable extension rather than an established finding, and the book does not always mark the difference.

The end of the pursuit phase is not the end of love. It is a handover to a different system.

Their argument that the same future-oriented circuitry that produces imagination, planning and abstraction also underlies dissatisfaction, restlessness and, at the extreme, disconnection from present reality.

They extend this to associations between creativity and certain mental illnesses, which is the most contested material in the book and is presented with more confidence than the epidemiological evidence supports.

The later chapters attempt to map political orientation onto dopaminergic versus here-and-now dominance, associating progressive politics with abstraction and future-orientation.

This is the weakest section by a substantial margin: speculative, under-evidenced, and resting on personality-politics correlations that are weak and contested. It should be read as opinion, and a reader would lose nothing by skipping it.

Their constructive conclusion: neither system alone produces a good life. Pure dopaminergic living is endless pursuit without satisfaction; pure present-focus lacks direction and achievement.

Their practical recommendations — deliberate present-focused activity, attention to sensory experience, savouring — are conventional and sound, and follow reasonably from the framework.

The first half is a genuinely good popular account of a well-supported and widely misunderstood piece of neuroscience. The second half extends the framework well past what it can carry.

Read the dopamine chapters carefully and the cultural and political chapters sceptically, noticing where a mechanism stops being explained and starts being applied.

The wanting/liking distinction alone justifies the book. Noticing that the intensity of wanting something predicts almost nothing about how much you will enjoy having it is genuinely useful, and it explains a large amount of ordinary disappointment.

And the prediction-error insight, which explains why variable rewards — in gambling, in notifications, in intermittent approval — are so much more compelling than reliable ones.
