The Neuroscience of Pleasure: Wanting, Liking, and Guilty Delights

The episode dives into why pleasure can feel complicated, blending neuroscience with everyday life. It explains that pleasure consists of a cycle with distinct parts: wanting, driven by motivation and brain reward circuits, and liking, the actual enjoyment once a reward is obtained. Dopamine is highlighted as a key driver of wanting rather than pleasure itself, while hedonic hotspots in the brain mediate liking. Guests discuss how guilt and social attitudes influence what we love, from guilty pleasures like dragon romance novels to the concept of pleasure activism. The conversation also offers practical guidance on healthy pleasure through variety and community, emphasizing meaningful, shared experiences over solitary indulgence.

Introduction: Pleasure Beyond Simple Joy

The episode from Short Wave brings together researchers and thinkers to examine pleasure as more than a gut-level feeling. Emily Kwong hosts a discussion about how we experience joy, guilt, and excitement, weaving together neuroscience and social psychology. Guests Sami Schalk, a pleasure activist, Morten Kringlebeck, a neuroscientist at the University of Oxford, Kent Berridge of the University of Michigan, and Kelly Goldsmith of Vanderbilt University contribute perspectives on why we love what we love and how social context can shape those preferences.

Section 1 — The Pleasure Cycle: Wanting and Liking

A central idea is that pleasure unfolds as a cycle with at least two components: wanting and liking. They are usually aligned, but can become uncoupled in circumstances like addiction. Emily describes a coffee morning as an illustration: anticipation (wanting) motivates action, while the actual taste and enjoyment (liking) occurs after the reward is obtained. The brain’s reward system, including regions like the nucleus accumbens and ventral striatum, signals anticipation and goal-directed behavior. "Dopamine is the most famous reward neurotransmitter in the brain, but it doesn't actually generate pleasure the way we once thought it did. It does, however, generate intense wants and urges." - Kent Berridge

Section 2 — Dopamine, Wanting, and Hedonic Hotspots

The conversation distinguishes wanting from liking, showing that dopamine primarily drives the wanting phase. Even when dopamine is manipulated, people can still like things, but may not work as hard to obtain them. Liking, in contrast, is tied to specific brain sites—hedonic hotspots—tiny regions that mediate pleasure and can be modulated by drugs to alter pleasure. The discussion emphasizes that pleasure is not a single neural hub but a network of interacting processes that together shape our experiences. "Liking lives inside of these tiny sites in the brain" - Kent Berridge

Section 3 — Guilty Pleasures, Social Signals, and Pleasure Activism

The episode explores guilty pleasures and the social dynamics that accompany them. Kelly Goldsmith discusses behavioral studies in which people who are nudged toward guilt rate enjoyable items more highly, suggesting guilt can paradoxically amplify pleasure. Sami Schalk adds that negative feelings about what we enjoy can limit connections with others, highlighting the role of social narratives in steering our tastes. The guests advocate for pleasure activism, encouraging people to embrace what brings joy while maintaining healthy boundaries and community connections.

"feeling guilty about doing something might actually make us enjoy that thing more" - Kelly Goldsmith

"there's a way that people just don't take seriously folks who are too open and joyful" - Sami Schalk

Section 4 — Healthy Pleasures through Variation and Community

The host and guests converge on a practical takeaway: the most fulfilling pleasures come from variation and shared experiences, not rigid moderation or sheer restraint. Mort Kringlebeck explains that meaningful pleasure often involves a sense of community and meaningful activities, which help sustain long-term wellbeing. The discussion frames pleasure as a spectrum rather than a binary good-bad choice, urging listeners to lean into different sources of happiness and to share joy with others to deepen its impact.

"it's not really about moderation and it's not really about will. It's about variation." - Morten Kringlebeck

Conclusion: Embracing Healthy, Shared Joy

The episode closes with a balanced approach to pleasure, encouraging curiosity, social connection, and openness about what brings joy, while acknowledging the brain's powerful mechanisms behind desire and reward. The takeaway is to celebrate the diversity of pleasures that foster community, meaning, and wellbeing, rather than demonizing them or treating joy as only a personal secret.
