Hi, this is Ray.

Quick embarrassing story about my relationship with being alone. Through most of my twenties, I structured my life so that I was almost never actually by myself. Not for any particularly principled reason. I just found solitude vaguely uncomfortable, so I avoided it. I had a roommate. I hung out with people constantly after work. I studied at coffee shops surrounded by strangers. Even when I was technically alone in my apartment, I had music playing, podcasts running, TV in the background, or phone conversations happening. The concept of just being alone with my own thoughts, in silence, without input, was so foreign that I don't think it occurred to me as something a person would deliberately choose.

The consequences of this pattern were subtle but real. I noticed, over years, that my thinking had become increasingly derivative. My opinions were mostly borrowed from whoever I'd talked to most recently. My understanding of my own preferences was fuzzy… I would default to whatever the group wanted because I hadn't spent enough time alone to figure out what I actually wanted. When I tried to solve problems, I would run through what other people would say rather than actually thinking about them myself. The constant social input meant I was rarely doing my own thinking. Someone else's thinking was always in my ears, on my screen, or in the room.

This changed by accident. During a period of upheaval in my late twenties, I ended up living alone in a new city for a few months, working remotely, with almost no local social network. The first few weeks felt like withdrawal. But by week three, something shifted. Ideas started arriving that I hadn't been able to access before. Problems I'd been unable to solve became solvable. My own preferences emerged from the fog. I noticed I was thinking more clearly than I had in years, and the difference was almost entirely that I was finally alone enough for my own cognition to have room to operate.

Today's newsletter is about that. What the research actually shows about voluntary solitude and cognitive function, why time alone is a learning input rather than a deficit, and how to actually make room for it if your life has become as socially saturated as mine was. This isn't about becoming a hermit. It's about reclaiming a cognitive resource that most modern people have quietly given up without realizing what they were losing. Let's get into it.

Before I get to the benefits, I need to name a crucial distinction the research keeps making. There's a difference between solitude and loneliness. These are related but not the same, and confusing them causes most of the cultural confusion about being alone.

According to research on the topic, voluntary solitude can foster creativity, emotional regulation, and introspection. Excessive alone time, especially when involuntary, can lead to loneliness and distress. Solitude is more beneficial for individuals with strong social support systems. Read this carefully. Voluntary solitude (chosen alone time in the context of a life that also has meaningful social connection) produces the benefits. Involuntary isolation, or solitude in the absence of social support, produces the harms. Same physical state. Wildly different psychological experience based on whether it's chosen and whether it exists alongside social connection.

The research on cognitive perception makes this even clearer. According to a 2025 study on how people think about solitude, our beliefs are malleable and changing how we interpret situations in our lives (e.g., via cognitive reappraisal) can powerfully shape emotion, health, and performance. As prior research has conceptualized the capacity for positive solitude as a skill that can be developed, there may be great potential for cognitive change to improve the way that individuals think about, and consequently experience, solitude. Positive solitude is a skill. Some people have it. Others don't. And the ones who don't can develop it. The people who benefit most from time alone aren't people with different personalities… they're people who have learned to relate to alone time as productive rather than distressing.

The direct cognitive benefits are worth spelling out. According to research on the topic, researchers have found that people are more likely to experience "aha" moments when they are alone and relaxed. These moments of insight often arise when your mind is free from external noise, enabling you to think more deeply and outside the box. When you're constantly surrounded by others, your decision-making and problem-solving processes may be clouded by external opinions and social dynamics. The insight-producing brain state is specifically alone-and-relaxed. Not alone-and-anxious. Not surrounded-by-others. The specific combination of solitude with relaxation is where the cognitive breakthroughs happen. If you're never in that state, you're missing a specific cognitive mode that supports learning.

The mechanism connects to what I've written about in previous newsletters regarding the default mode network. When you're constantly processing external input (conversations, media, notifications), your DMN doesn't get the runtime it needs to do its consolidation and integration work. Solitude, especially quiet solitude without media, is when the DMN can actually operate. This is when the ideas connect. When the material integrates. When the "aha" arrives.

Let me get specific about why solitude matters for learners in particular. This isn't just general wellness advice. It's cognitive infrastructure for learning.

Space for your own thinking. When you're constantly around others, your thinking becomes increasingly reactive to theirs. You're always responding, agreeing, disagreeing, translating. Alone time is when your own thinking can develop without immediate reference to other people's. This original thinking is what deep understanding requires. Without it, you can accumulate information without ever making it your own.

Integration of what you've learned. Learning isn't just encoding. It's connecting new material to what you already know, extending it, playing with it, seeing its implications. This work happens best in unstructured alone time. When you're always with others or consuming media, the material you've encoded doesn't get the integration time it needs. It stays isolated and eventually fades.

Consolidation of memory. As I've covered in the rest and default mode network newsletters, memory consolidation happens during specific brain states… including waking rest with unstructured thought. Solitude in the right form facilitates this. Constant social or media input suppresses it. Same amount of study time, different amount of consolidation, different long-term retention.

Self-knowledge for effective learning. As I've written about in the strategy and metacognition newsletters, effective learners have accurate self-knowledge about how they learn, when they focus best, what they actually understand, and what they don't. Building this self-knowledge requires alone time to notice your own patterns without external input distorting them. The person who's never alone often doesn't know themselves well enough to study effectively.

Emotional regulation and stress management. According to research on solitude, spending time alone reduces stress and anxiety. As a result, spending time alone can decrease our risk of mental disorders like depression. Learning under sustained stress is much harder than learning under baseline conditions. Solitude that produces stress reduction is directly supporting your cognitive capacity for the actual work.

Development of original perspectives. The learner who develops genuinely original perspectives on their material (not just accurate reproduction of what they've read) typically does so through periods of solitary thinking. This original engagement is what distinguishes surface learning from deep understanding. It requires alone time to happen.

Here's something worth naming honestly. Modern culture has developed a specific hostility toward voluntary solitude that makes this cognitive practice harder to reclaim than it should be.

According to research on solitude, empirical evidence indicates that solitary individuals are regarded as inferior to, and less worthy than, individuals who are more sociable. The cultural stigma is real. People who spend time alone are perceived as antisocial, sad, or defective. This stigma affects even people who intellectually understand the benefits of solitude… it produces a low-grade discomfort with being alone that pushes people back toward social saturation even when solitude would be better for them.

The technology environment amplifies this. Every device we carry is designed to prevent solitude. Notifications interrupt any moment of quiet. Social media manufactures the sense of ambient social presence even when we're physically alone. The very concept of being alone with your thoughts, without any external input, has become genuinely rare in modern life. Most people who think they spend time alone are actually spending time with mediated social input from their devices.

This matters because the cognitive benefits I've been describing don't come from "physically alone but glued to phone." They come from actually being alone in a way that lets your own cognition have room. In Elden Ring terms, you can't level up in the Roundtable Hold surrounded by NPCs talking at you constantly. You need to actually spend time in the world, alone, doing your own thing, if you want to develop. Same for your brain.

Let me be specific about what produces the cognitive benefits, because "alone time" gets used loosely.

Physical solitude. No other people physically present. This alone isn't enough, but it's a starting condition.

Media-free solitude. No podcasts, videos, music, or scrolling. The consumption of media isn't solitude… it's mediated social presence. Real solitude means you're actually alone with your own thoughts, not with someone else's voice in your ears.

Unstructured time. Free enough from external demands that your mind can wander. Structured tasks (even ones you do alone) engage different cognitive systems than open time.

Voluntary choice. You chose to be alone. It's not being imposed on you. The chosen quality is what produces the psychological benefits.

Context of social support. Ideally, alone time exists in a life that also includes meaningful social connection. Solitude in the total absence of social connection tends toward loneliness rather than restorative solitude.

The combination of these features produces something increasingly rare in modern life. A quiet walk without a podcast. Time in a room with your own thoughts and no screen. A solo dinner without your phone. Sitting in a park doing nothing. These are the conditions under which the cognitive benefits happen.

Okay, the practical part. If your life has become as media-saturated and socially-saturated as mine was, here's how to actually build solitude back in.

Schedule it explicitly. Solitude that "happens when you have time" doesn't happen. Solitude that's on your calendar happens. Block specific time. Defend it. Treat it as important because it is.

Start small. If you haven't been alone with your thoughts in years, an hour of unstructured solitude will feel unbearable. Start with 20 minutes. Extend gradually. The tolerance builds. As one summary put it, reframing solitude as beneficial to one's well-being helps people experience a period of solitude more positively. The skill develops with practice.

No devices during solitude time. This is the hard one. Phone in another room. Not just face-down, in another room. The temptation to check something will arise repeatedly. Resist it. The value comes from the not-checking. In Persona 5, Joker doesn't get his growth from constantly checking his phone. He gets it from time in the Palace working through things directly. Same for you.

Try walks without input. A walk without a podcast, music, or phone in your ear is one of the highest-value solitude practices available. Your body is moving. Your mind has room to wander. Insights arise. Problems resolve themselves. Start with 20-minute walks. Build up.

Try meals alone without media. Eating a meal without watching or listening to anything is genuinely difficult if you've never done it. Your mind will beg for input. Give it your own thoughts instead. Notice what you actually feel about the food, the day, whatever comes up.

Try one hour a week of unstructured alone time. Not doing anything. Not planning. Not consuming. Just being alone with your own mind. If this feels impossible, you're demonstrating why you need it.

Notice the discomfort without acting on it. The initial resistance to solitude is normal. Most modern people experience it. The resistance itself isn't a signal that you should return to constant input. It's just what withdrawal from constant stimulation feels like. Sit with it. It passes.

Combine solitude with something restorative. Nature. Warm baths. Cooking simple food. Reading physical books. Journaling by hand. These activities support solitude by giving your body something calming to do while your mind has room to wander.

Some honest caveats.

This isn't about becoming anti-social. As the research is clear, solitude works best in the context of a life that also has meaningful social connection. Cutting off social relationships entirely produces isolation, which has different effects than voluntary solitude. Both social connection and alone time matter. Neither replaces the other.

Individual variation is real. Some people need more solitude than others to function well. Introverts often benefit from more of it than extroverts. Pay attention to your own patterns rather than assuming everyone needs the same amount.

Chronic isolation is different from voluntary solitude. If you're already isolated involuntarily, more alone time isn't the answer. In that case, building social connection is the intervention. The benefits of solitude assume you have social support that exists alongside your alone time.

Some people use "alone time" to avoid needed relationships. This is a real pattern. If your solitude is actually avoidance of relationships you should be building, it's not producing the benefits I'm describing. Honest self-assessment matters here.

Here's what I want you to take from all this. Voluntary solitude is a cognitive input that most modern people have quietly eliminated from their lives, largely without noticing. The result is a slow degradation of the specific cognitive functions that solitude supports… original thinking, insight, integration, self-knowledge, emotional regulation. Learners who never have real alone time are missing something that no amount of study can compensate for.

If you've felt like your thinking has become increasingly derivative, your insights rarer, your understanding of your own preferences fuzzier, please consider that the missing variable might be solitude. The kind that most modern life actively prevents. The kind that requires deliberate reclamation.

The good news is that solitude is available to anyone. It doesn't cost money. It doesn't require special skills. It requires only the willingness to be alone with your own mind for periods of time, without input, without company, without escape from your own thoughts. This is a modest ask. It's also a substantial cognitive intervention if you actually do it consistently.

Your brain has capabilities that only emerge when it has room to operate. The room comes from solitude. Give yourself that room. What emerges will surprise you.

In Chrono Trigger, some of the most important moments happen when a single character is alone with their own choices… Frog at the Denadoro Mountains, Robo at Fiona's Forest, Magus at his castle. Alone time is when the characters actually develop into who they need to become. Your learning works the same way. You need time alone with yourself to develop into who you're becoming. Make the room. The rest will follow.

Keep learning (and keep making room for yourself),
