--- title: "My son, brainrot and me: a father's investigation inside the dopamine machine" subtitle: "A father's investigation inside the dopamine machine" description: "My son was getting irritable after his Roblox videos. Instead of speculating, I analyzed the transcripts of his 10 favorite videos. Here is what the data said." date: 2026-06-09 slug: brainrot-machine-a-dopamine lang: en tags: [parenting, screens, dopamine, roblox, brainrot, attention] --- ------------------------------------------------------------------------ ### Act I --- The symptom It all started with a stupid argument. "Turn it off, time's up." An ordinary sentence. Except that evening, the reply wasn't a normal teenage sigh. It was curt, raw, almost hostile --- as if I had just ripped something away from him. Ten minutes later, he was himself again. But in between, there had been that **moment**: a kid I didn't recognize, irritable, shut down, somewhere else. And it wasn't the first time. The pattern kept coming back: he would be watching Roblox videos --- a YouTuber named **Kevko**, some *Steal a Brainrot*, some *Lucky Block* --- and when I interrupted him right in the middle, things went sideways. Not afterward. **Right in the middle.** I could have left it there. Declared "screens are bad," set a rule, and worn myself out enforcing it. But I had a more precise hunch, and a son too smart to swallow a ban without an explanation. I needed to understand *exactly* what was going on in his head. And for that, I needed **data**, not impressions. ------------------------------------------------------------------------ ### Act II --- The investigation First hypothesis, the most worrying one: what if the content itself was the problem? A lot of Roblox videos revolve around *stealing, beating, trapping, trolling, winning against everyone else*. Was my son spending his afternoons internalizing a logic of competition and domination? The trouble was, I had no idea. I *felt*. And when it comes to raising kids, gut feeling is the shortest road to unfairness. So I decided to do what a journalist would do: **read the sources**. Not half-watch two videos --- pull the **full transcripts** of the channel's biggest videos and analyze them, word by word. I identified his **10 most-viewed videos** (from 426,000 to 786,000 views), extracted the automatic French subtitles, and cleaned everything up: **48,437 words** of transcript. Then I counted. I sorted the vocabulary into broad families --- urgency, competition, reward, accumulation, conflict, mockery --- and measured their frequency per 1,000 words. That's when the numbers started talking. And they didn't say what I expected. | Theme (across 10 videos, 48,000 words) | Frequency /1,000 words | |----|----| | **Scarcity / accumulation** (`encore`, `obtenir`, `débloquer`, `rare`) | **11.4** | | **Urgency / speed** (`vite`, `vitesse`, `allez`, `go`) | **10.1** | | Reward / money (`robux`, `million`, `argent`) | 6.3 | | Competition / winning | 5.0 | | Excitement / superlatives | 3.3 | | Theft ("steal") | 2.3 | | **Conflict / domination** | **0.4** | | **Mockery / trolling** | **0.5** | The aggressive content I had been dreading --- domination, mockery, trolling --- was **practically nonexistent**: 0.4 and 0.5 per 1,000 words, basically statistical noise. My son wasn't learning to crush other people. What dominated was something else entirely: **accumulation and urgency.** *Always one more item. Always faster.* The two most frequent theme words on the entire channel were "encore" (more) and "vite" (fast). And when I measured interjections and laughter --- a proxy for intensity --- some videos climbed to **23 excitement markers per 1,000 words**, without a single pause for breath. I had the wrong suspect. The danger wasn't *ideological*. It was **physiological**. ------------------------------------------------------------------------ ### Act III --- What we found All that was left was to check my numbers against the science. And that's when everything clicked into place. **1. The unpredictable reward machine.** The heart of *Steal a Brainrot* is chance: the Lucky Block that *might* drop a rare brainrot, the passive income that keeps ticking and nudges you to log back in. That is precisely **variable-ratio reinforcement** --- the mechanism casinos have exploited for a century because it's the most addictive one there is. The brain releases dopamine **while anticipating** the reward, not upon receiving it. You stay in permanent tension: *what if the next one is the one?* **2. It's not the violence, it's the pace.** The key piece I found in a study published in the journal *Pediatrics* in 2011. Researchers showed children **9 minutes** of a cartoon that was simply *fast* --- a cut every eleven seconds --- with no violence at all. Right afterward, their ability to concentrate and their patience were **measurably degraded**, compared with children who had watched a slow cartoon. Nine minutes. The Kevko format is exactly that: saturated delivery, choppy editing, zero breathing room. **It isn't what he says that acts on my son. It's the speed.** **3. And that's why it was blowing up at home.** When I cut him off in the middle, my son's brain was still "up." And the American Academy of Pediatrics says it explicitly: when the screen goes off, **dopamine drops, and that drop leaves us grumpy and irritable.** The irritability I was taking full in the face wasn't insolence. It was a **predictable chemical state** --- the backlash of an excited state that hadn't been allowed to come back down. The cruelest part is the relational effect. The content put him in a state where he was **pushing away, without meaning to, the people in the same room.** And the trap of *"always one more"* is that there is never a good moment to stop --- so never really a moment when he was *present* with us. The real cost wasn't screen time. It was real moments, with real people, disappearing. **The nuance, because we have to stay honest.** No, brainrot doesn't literally "rot the brain" --- it became the Oxford dictionary's word of the year in 2024, but it's a cultural marker, not a diagnosis. No, the famous "dopamine detox" isn't a real scientific concept: you don't "reset" your dopamine by switching off screens. And yes, brainrot is also kids' humor, a generational language. My son is not in danger. But he is, by design, **being manipulated** --- and that is something we can fix. ------------------------------------------------------------------------ ### Act IV --- What we're trying to do about it I decided to make a bet: on his intelligence. No head-on ban --- a clever kid works around it and resents you for it. Instead, I switched sides. The message was no longer *"Dad forbids it"* but *"engineers paid millions are playing with your brain, and I'm on your team against them."* Nothing annoys a teenager more than being manipulated. That was my best lever. Then I proposed an **experiment**, because he likes science: > "For one week, just observe your mood in the 10 minutes after you stop. Rate it out of 10. And compare: when someone cuts you off in the middle, versus when *you* pick the moment to stop. If I'm wrong, I'll admit it. But look at the data yourself." Giving him back control is precisely what the research identifies as the factor that most reduces end-of-screen meltdowns. And turning a recurring argument into a **joint investigation** takes him out of the defensive position. Finally, we watched some videos **together** --- not sermons, but breakdowns made by people a teenager respects: - **"Dopamine" series --- ARTE, TikTok episode** (~9 min): dissects, technique by technique, the app he knows. Clinical tone, zero moralizing, the "they're manipulating me" click. → https://www.youtube.com/watch?v=-pOWdBpVR3s - **"Et tout le monde s'en fout" --- \#59 Les algorithmes** (~7 min): funny, on your side, never preachy. → https://www.youtube.com/watch?v=5NiVg4DBJrI - **Tracks ARTE --- "Brainrot: est-ce qu'internet fait pourrir nos cerveaux ?"** : tackles his universe head-on. *(Preview it first.)* → https://www.youtube.com/watch?v=ubT8hS0lAlg - **Stupid Economics --- "L'économie de l'attention"**: the "your attention is the product being sold" angle. → https://www.youtube.com/watch?v=rMV1WaWGb3I - **Tristan Harris --- TED Talk (French subtitles)**: the former Google engineer who sounded the alarm first. Maximum credibility. → https://www.ted.com/talks/tristan_harris_how_a_handful_of_tech_companies_control_billions_of_minds_every_day?language=fr The plan: start with the first one (9 minutes, he recognizes his app), let him comment, don't draw the conclusion for him. The short, factual format does the work on its own. ------------------------------------------------------------------------ ### Epilogue I haven't "won." This isn't a battle you win in one evening, and that was never the point. But something has changed: my son stopped seeing a father who confiscates, and started seeing a mechanism that manipulates him. He has a vocabulary to name it now. And between us, conversation has replaced argument. The content he watches isn't evil. It isn't even ideological --- my own data proved it to me. It's just a machine, very well designed, to keep a child's brain in a state of maximum excitement and make it come back. Understanding the machine is already halfway to breaking free of it. And that is a bet I'm willing to make on my son's intelligence. ------------------------------------------------------------------------ ## Sources & references **On dopamine and post-screen irritability** - American Academy of Pediatrics --- *Screen Time and Temper Tantrums* (the dopamine drop when the screen goes off makes kids irritable): https://www.healthychildren.org/English/family-life/Media/Pages/screen-time-and-temper-tantrums-helpful-tips-for-parents.aspx **On pacing/editing that degrades attention** - Lillard, A.

Acknowledged limitation: a transcript measures words, not sound volume or editing pace --- and that pace is precisely what the science identifies as the most decisive factor. The figures are therefore a converging clue, not a direct measurement of overstimulation.*
