Dr. Jud on the Making Sense Podcast: The Unquiet Mind

Overview

In episode 179 of the Making Sense podcast, Sam Harris sits down with Dr. Jud for a wide-ranging conversation about the neuroscience behind addiction, craving, and how mindfulness can address both. Harris — a neuroscientist and experienced meditator himself — pushes Dr. Jud on the mechanisms beneath the surface: how reward-based learning shapes behavior, why subjective bias plays a bigger role in addiction than most people realize, and what real-time brain imaging reveals about the meditating mind.

The discussion goes deep into the habit loop that drives compulsive behavior — from cigarettes to smartphones to rumination — and how the same neural pathways that create addiction can be redirected through mindfulness practice. Dr. Jud shares findings from his lab’s research on smoking cessation through mindfulness, including studies showing that mindfulness-based interventions outperformed the American Lung Association’s gold-standard program. They also explore the neuroscience of the sense of self: what happens in the brain when meditators report ego dissolution, and how real-time neuroimaging (fMRI neurofeedback) has allowed Dr. Jud’s team to observe these shifts as they happen.

A particularly striking thread runs through the conversation: the distinction between dopamine-driven reward and genuine happiness. Dr. Jud explains that the dopamine system evolved to drive seeking behavior — always chasing the next thing — while contentment and well-being operate through different neural mechanisms entirely. This insight is central to understanding why breaking bad habits requires more than substitution: it requires a fundamental shift in how you relate to craving itself.

Key Takeaways

• Reward-based learning is the engine of addiction: The brain learns habits through a simple loop: trigger, behavior, reward. This same process underlies everything from substance addiction to anxiety and compulsive phone checking.
• Mindfulness outperformed standard treatments for smoking cessation: Dr. Jud’s clinical trials showed that curiosity-based mindfulness training helped smokers quit at higher rates than traditional cognitive-behavioral approaches.
• Dopamine-driven reward is not the same as happiness: The dopamine system drives seeking and craving — always wanting more. Genuine well-being comes from a different process rooted in present-moment awareness, not constant pursuit.
• Real-time neuroimaging reveals meditation’s effects: Dr. Jud’s lab has used fMRI neurofeedback to show meditators their brain activity in real time, demonstrating measurable changes in default mode network activity during mindfulness practice.
• Effort and effortlessness in meditation: Dr. Jud and Harris discuss how trying too hard in meditation can activate the very brain networks you’re trying to quiet — and how mindfulness exercises that emphasize curiosity over concentration can be more effective.

In this episode of the Making Sense podcast, Sam Harris speaks with Dr. Jud about addiction, craving, and mindfulness. They discuss the nature of reward-based learning, the role of subjective bias in addiction, the neuroscience of craving, the neural correlates of the sense of self, real-time neuroimaging, effort and effortlessness in meditation, smoking cessation through mindfulness, the difference between dopamine-driven reward and happiness, how to make meditation a habit, working with anxiety, and other topics.
