It’s the molecule of learning — and understanding that changes everything about addiction, our relationship with social media and modern life. In this episode of The Renaissance Doctor, clinical psychiatrist Elisabetta Burchi reframes addiction not as a disorder of reward, but as a disorder of learning — and asks what it means that the first generation of children is having its reward system shaped, from infancy, by algorithms. ⚠️ This episode discusses addiction. If you or someone you know is struggling, please reach out to a qualified professional or a local support service. ▶ THIS EPISODE IS FOR YOU IF YOU… you feel pulled by your phone in ways you can’t fully explain — and a little uneasy about it; you’re a parent or educator worried about what screens are doing to children’s developing minds; you’ve heard ‘dopamine detox’ everywhere but want the real neuroscience; you’ve tried willpower, deleting apps, or shaming yourself — and it didn’t hold; you’ve struggled with (or love someone who struggles with) a substance or behaviour, and want understanding without stigma; you want to reclaim agency and pursue what’s meaningful rather than just what’s available. ▶ WHAT YOU’LL LEARN why learning is key characteristic of our brain and how dopamine iunderpins it; the crucial difference between wanting and liking; why addiction is best understood as a disorder of learning, not simply of reward; how certain algorithms and behaviors train the brain’s ancient seeking system toward shallow loops; why the moral framing of addiction is both scientifically wrong and actively harmful; practical counter-cultural ways to reset your reward system and recover agency.

This is something I genuinely believe and often find myself saying to my patients as I try to, on one hand, help them rediscover meaning in struggle, discomfort and sometimes even in suffering and, to the other hand, as I try instead to uncover the illusion of easy happiness that often lies behind behaviours and habits requiring little effort or frustration, but ultimately offering little meaning in return. Nothing that is existentially valuable in life comes without effort. Most people immediately recognise this as a wise, and self-evident truth. And yet, this is also a deeply provocative statement. Because we are living in a civilization increasingly organised around a radically different premise, modern environments provide unprecedented access to an endless stream of stimuli capable of generating immediate gratification. This might not be absolutely negative in itself, but, as we know, biological systems tend to follow the path of least resistance and, when that path is constantly available, it risks becoming the only path we pursue. So a reasonable hypothesis, and concern is that when some rewards are easily accessible, we may stop pursuing the goals that require effort – goals that often entail far greater resistant meaning. You might be familiar with an influential book entitled ”The Anxious Generation”. My thesis here is that we should also be concerned about another phenomenon, what I will provocatively call the promotion of “an addicted Generation”. This is the question I want to explore in this episode: What happens to a person, to a generation, when a civilization is built around easy access to rewards rather than cultivating meaning? What happens when the brain’s most essential learning system operates in such an environment? My name is Elisabetta Burchi. I’m a physician, clinical Psychiatrist and host of the Renaissance Doctor. This podcast exists to explore an ambitious question: what does it mean to be human and to flourish in the 21st century? Today we are going to talk about learning and addiction, learning as a key feature of brain functioning and addiction as a form of disrupted learning. We will leverage neuroscience to describe the concepts and we will embrace sociological and ethical perspectives to discuss the tools we have to not let the environment entirely shape our lives. I’ve always been fascinated by patterns- by the search for underlying principles and invariant logics capable of explaining seemingly different phenomena; not only as an intellectual exercise, but perhaps as a way of making sense of complexity and orienting myself in the world. When I began my training in Psychiatry, I found myself driven by the same attitude. What distinguishes mental health from mental disorder ? And what ultimately justifies my intervention as a Psychiatrist? Over the years my answer has evolved. Yet, from the very beginning, one aspect stood out. I soon recognised that what often characterises mental suffering is a reduction in a person’s sense of agency. Rigid beliefs, intrusive thoughts, overwhelming emotions, compulsive behaviours: in different ways they all constrain our ability to choose. And because I’ve always believed that the capacity for self-determination is one of the defining features of human beings, I came to see Psychiatry, at least in part, as an attempt to restore that capacity: to restore flexibility and help individuals recover the ability to learn, adapt, and consciously shape their lives. In this view, treatment is not merely about making people feel better. It is about helping them regain agency. It was through this lens that I became particularly interested in addiction. Partly because addictive behaviours seemed to be becoming increasingly common in society, but also because addiction appeared to represent, in its purest form, the very phenomenon that had first drawn me to Psychiatry. If agency is central to mental health, addiction may be one of the clearest examples of what happens when agency is progressively lost. In addiction, behaviour is initially voluntary. Then it becomes habitual; eventually it becomes compulsive. The person continues to act, but increasingly loses the ability to choose otherwise. Next
