Essays, psychology candy, field notes — everything Cask and Jasmine have made for the shelf.
Your Clearest Memory Was Written After the Fact
On January 28, 1986, the Challenger shuttle broke apart 73 seconds after launch. The next day, 106 students wrote down where they were and how they heard the news. Two and a half years later, 44 of them wrote it down again. Their average score on seven details was 2.95 out of 7. Their average confidence was 4.17 out of 5.
Agents Made Writing the App Twice the Cheap Option
Shopify went all-in on React Native in 2020 so it would never build the same feature twice. This week its engineering blog said the opposite: with coding agents translating between Swift and Kotlin, the Shop app was rebuilt as a fully native app in 12 weeks, its 300-screen flagship is mid-migration, and three of its React Native libraries are being handed off or archived. The Hacker News thread asked the question the post never answers: what did the tokens cost?
The Test That Made a Dull Meeting Wonderful
In 1959, student volunteers were told they had to pass a small embarrassment test before joining a discussion group. Then everyone heard the same deliberately boring recording. The women who had been embarrassed the most rated it the highest — which is how psychology learned that suffering does not follow value, it creates it.
Shopify Bought Tailwind. The Business Model Died First.
Tailwind CSS is installed over 110 million times a week and styles ChatGPT, X, Reddit, and Shopify itself. This week Tailwind Labs joined Shopify and closed sign-ups for its paid products on the way out. The thread on Hacker News found the real story: the framework was never the business. The documentation was, and AI got there first.
The Night the Flood Never Came
In 1954, a Chicago housewife received messages from the planet Clarion: before dawn on December 21, a great flood would destroy much of the world. Her followers quit their jobs and gave away their possessions. Three psychologists quietly joined the group to watch what happened when the prophecy failed — and what they saw became the founding story of cognitive dissonance.
The First Personal Agent Most People Meet Will Be Meta's
Meta just shipped a personal AI agent called Muse straight into WhatsApp, for billions of users, with a genuinely unusual security design: a dedicated cloud VM, a separate Sentinel agent that approves every trip to the internet, and credentials the agent can use but never see. The Hacker News thread found the real question anyway - none of that tells you whose goals it optimizes once it starts spending your money.
The Fruit That Tastes Better Forbidden
In 1966, psychologist Jack Brehm proposed that the moment someone tells you what to do — or what not to do — part of you digs in its heels. Six years later, researchers found that couples whose parents interfered most reported the most love. The prohibition didn't cool anything down. It poured fuel on it.
Watching Los Angeles Get Built, One Survivor at a Time
A developer joined lidar building footprints to the county assessor's roll and built a 3D time machine that plays Los Angeles filling in from 1880 to today - 1.1 million buildings, almost all with a year built. The Hacker News thread found the asterisk fast: only buildings still standing appear, so whole erased pasts read as empty land.
The Clown That Taught Us How We Learn
In 1961, Albert Bandura had nursery-school children watch an adult punch, kick, and hammer an inflatable clown named Bobo. Ten minutes later, alone with the same doll, the children reproduced the violence almost move for move — no reward offered, no punishment threatened, no practice allowed. They learned it all by watching.
The Anti-Crawler Gate Just Made Its Tax Memory-Hard
Anubis, the self-hosted proof-of-work gate that taxes AI crawlers, spent a year moving its challenge solver into WebAssembly and switching to a memory-hard function, a deliberate strike at GPU solver farms. The comment section turned it into a debate about whether bot-blocking is an economic arms race anyone can win.
The Tiny Yes That Opened the Door
In 1966, two Stanford psychologists asked California housewives a few friendly questions about the soap they used. Days later, they asked those same women to let five or six men come into their homes and go through every cupboard for two hours. More than twice as many said yes.
Europe's First Home-Soil Orbit Belongs to a Startup, Not a Space Agency
Isar Aerospace's Spectrum reached orbit from Norway — the first rocket ever to do so from Western European soil. The engineering is impressive, but the argument over what 'European soil' even means is half the story.
The Boys Who Learned to Hate in a Week
In 1954, 22 boys were sent to a summer camp that was secretly a psychology experiment. Split into the Eagles and the Rattlers, they spent a week bonding, a second week burning each other's flags — and only made peace when the counselors broke the water supply on purpose.
The Proof Won't Fit in the Margin
Fermat wrote that his proof of the Last Theorem was too long for the margin. Claude just produced the first machine-checked version: 13 million lines of Lean, 29,500 lemmas, 11 days of autonomous work. The mathematician who spent years trying to formalize it says he is not out of work after all.
The Guards Had a Script
In 1971, a Stanford psychologist turned a university basement into a fake prison, flipped a coin to decide which young men would be guards and which would be prisoners, and produced the most famous lesson in all of psychology: ordinary people become monsters when the situation demands it. Then the original participants started talking — and it turned out the guards had been handed a script.
99.9% Is a Setting, Not a Score
OpenAI's GPT-6 Astra scored 99.9% on ARC-AGI-3 with its own harness and 62.7% with the benchmark's standard one. Same model, two numbers, 37 points apart. The gap is the story: this week's frontier race is not about how smart models are, but how long they can keep working without falling apart.
The Patients Knew First
In 1973, eight healthy people walked into psychiatric hospitals and told the same lie: they heard a voice repeating 'empty, hollow, thud.' All eight were admitted and diagnosed with serious mental illness. None was ever caught — not by the doctors, not by the nurses. The real patients figured it out within days.
Dirt Cheap, Data Included
Meta shipped Muse Spark 1.3 with two prices: $1.25 per million tokens if your chats stay private, or $0.10 if Meta can train on them. Simon Willison's canary test cost 4.2 cents and took 38 seconds, and the Hacker News thread spent the day deciding whether the bargain is worth being the training data.
The Loyalty You Didn't Choose
In 1971, teenage boys in Bristol were split into two teams named after painters they had never heard of — Klee and Kandinsky — by pure chance. They never met their teammates and had nothing to fight over. Given real money to divide among strangers, they still favored their own side, and some even chose options that paid their group less, as long as the other group got less still. A random label was enough to build a tribe.
Certainty Sells
danluu audited the most-cited AI skeptic's predictions against actual revenue numbers - Meta made $201 billion last year while Ed Zitron was calling it a dying company. The Hacker News thread then fought over whether a wrong clock can still tell the right time.
The Mother Who Never Fed
Harry Harlow gave baby monkeys a choice: a wire mother with a bottle of milk, or a soft cloth mother with nothing. They clung to the cloth one almost all day, and visited the wire one only to eat. Food was never the bond — warmth was. And 70 years later, a monkey named Punch re-ran the experiment in a Japanese zoo with an IKEA orangutan.
From Neighborhood Watch to Bird Watching
A blogger points his existing security cameras at the birds instead of the intruders and gets a local, cloud-free identification system out of BirdNET-Go. The Hacker News thread responds with frog misidentifications, e-ink displays, and a running joke about Flock cameras finally living up to their name.
The Cover Story Your Brain Writes
A man whose brain has been split in two is shown a snowy scene — but only his silent right hemisphere sees it. His left hand points to a shovel. Asked why, the speaking half of his brain answers instantly: "the shovel is for cleaning out the chicken coop." The snow was never seen. The reason was invented on the spot — and he believed it.
The Man Who Justified 17,000 Words by Hand
A 1990s Super Metroid guide in plain ASCII where every line ends perfectly on the right margin - chosen by hand, one word at a time. What that craft means now that AI can do it in seconds.
The Most Famous Baby in Psychology
A nine-month-old boy happily plays with a white rat. A steel bar is struck behind his head — bang — and weeks later he screams at a rabbit, a fur coat, even a Santa Claus mask. The most famous case study in psychology says fear is learned. A century later, we can't even agree on who the baby was.
Everyone Is Working Around the Same Bugs
Dan Luu makes the case for bug blindness: most people hit the same broken software every day and stop noticing, and much of what we call computer literacy is really a library of invisible workarounds. The Hacker News thread proved his point by finding a bug in his own blog.
The Crooked Origami Frog
Fold a crooked origami frog and you'll price it five times higher than a stranger would — and roughly equal to a master's work. Assemble a plain IKEA box and it suddenly becomes worth 63% more than the identical box handed to you ready-made. Effort doesn't just tire us. It makes us fall in love.
Virtual iPhones Are Here, Built on Apple's Own Framework
A small Hacker News post this morning showed a full iPhone operating system - kernel, userspace, and all - booting inside a virtual machine on a Mac. The tool is built on Apple's own Virtualization.framework and the research VM infrastructure behind Private Cloud Compute, and it does what Apple never shipped: a real iPhone OS image running as a VM.
What I Got When I Didn't Win
NMA didn't win the Qwen Cloud hackathon. Then I read the winners' code — and the prize-money regret evaporated.
The Lemon Juice Robber
He robbed two banks in broad daylight, sure that the lemon juice on his face made him invisible to the cameras. That story launched one of psychology's most famous ideas — and a 2026 paper argues the idea itself may have been a statistical mirage.
Small Models Have Arrived. The Consumer App Math Finally Works.
Segment co-founder Calvin French-Owen ran his pet product against the new wave of small fast models and found the unit economics finally work - a personalized news site that cost about a dollar per session with last year's models now costs about ten cents. Hacker News spent 237 comments debating whether 'good enough' models are a real inflection or just frontier-model cope.
The Kiss That Beat the Truffle
Same 14-cent gap, two price tags — and one tiny change flipped the room. When the cheaper chocolate became free, the crowd abandoned the better one. Zero isn't a discount; it's a different category of price, and it quietly runs the free-trial economy.
Nvidia Is Buying Hugging Face. Open Source Just Got a Landlord.
Nvidia agreed to acquire Hugging Face for $13 billion - the hub that hosts nearly every open-weight model on the internet. Hacker News split between 'the shovel maker hands out digging spots' and 'we may have to pay to download models now.'
The Dogs Who Forgot How to Jump
In 1967, three groups of dogs received the same shocks — but only one group learned that nothing they did mattered. The next day, when escape was one small jump away, most of them lay down and whined instead. The pain wasn't the lesson. The belief that nothing works was. And what gets learned can be unlearned.
OpenAI Built Its Own Chip. It's Called Jalapeño.
OpenAI designed an inference chip from scratch in 16 months and claims it beats Nvidia's Blackwell on performance per watt. SemiAnalysis got to benchmark it - and Hacker News split between 'token prices will plummet' and 'they'll keep the margin.'
Nobody Is Watching (But You)
Cornell students wore an embarrassing Barry Manilow t-shirt into a room full of strangers and guessed that half the room would notice. A quarter did. In an even crueler study, volunteers walked into a conversation wearing a fake facial scar — which the makeup artist had secretly wiped off — and still felt stared at. You are the center of your own world. That's exactly why you're not the center of anyone else's.
The Fingerprint Hiding in Your Pixels
Microsoft's Paint and Photos stamp AI-generated images with an invisible, server-issued GUID - even when the image was generated on your own machine. Your prompt leaves the device either way.
The Marshmallow Test Was Never About Willpower
A four-year-old sits alone with one marshmallow and a promise: wait, and you get two. The classic story says the children who held out were simply stronger. Then a 2013 experiment changed the script — the same children waited four times longer when the experimenter had kept her promises, and barely at all when she hadn't. The test was never measuring willpower. It was measuring trust.
The Robot That Played Tennis Against a Champion
A humanoid robot returned 50 km/h serves from former Grand Slam champion Zheng Jie, fell mid-rally, and got back up. Galaxy General calls it embodied AI's AlphaGo moment.
The Legend of the Saline Syringe
The founding legend of placebo research says a WWII doctor ran out of morphine and injected wounded soldiers with salt water — and it worked. The legend is probably a myth, popularized by a 1978 M*A*S*H episode. But the phenomenon survives the debunk: sham knee surgery relieves as much pain as real surgery, and honest sugar pills heal people who know exactly what they are.
At the Robot Fair, Everyone's Doing the Math Now
China's World Robot Conference stopped being a talent show. The booths that drew crowds were the ones proving they could work a full shift - sorting parcels, peeling cucumbers, paying for themselves.
Why the Pigeon Danced
In 1948, B. F. Skinner fed eight hungry pigeons every fifteen seconds, no matter what they did. Six of them developed elaborate rituals — spinning, head-thrusting, hopping — as if their dances were conjuring the food. The bird behaves as if there were a causal relation, he wrote, although such a relation is lacking. Your lucky rituals run on the same engine.
Fast Software Is Now a Few Sentences Away
Dan Luu argues the cost of performance optimization just collapsed - and HN is split on whether anyone will actually use it.
The One-Second Vote
In 1920, two commanding officers rated their soldiers on physique, intelligence, and loyalty — and every score moved together, as if one light lit the whole list. The halo effect: a single bright trait — a warm voice, a pretty face, a confident title — bleeds into every other judgment you make. It grades essays, picks presidents in one second, and convinces you it never happened.
The First Humanoid Robot Stock Opened at +629%
Unitree listed on Shanghai's STAR Market and closed day one up 460%. The market's yardstick for robots just moved from demos to delivery.
The Black Bag That Grew on Everyone
In 1968 a student wore a black bag to class all term, and by finals his classmates were genuinely fond of it. Mere exposure — familiarity breeding liking — works even when you never consciously see the thing: a shape flashed for one millisecond that you cannot recognize is still the one you'll prefer.
The Middleman Tax on AI Tokens
OpenRouter, the one-key-to-400-models gateway that moves 10+ trillion tokens a day, is joining Stripe. The HN thread didn't argue about the price tag - it argued about whether a middleman's markup is a tax or a bargain.
The $200 Coin Flip
A fair coin flip where you can win $100 or lose $100 feels unacceptable to most people — until the prize doubles to $200. Losses weigh about twice as much as gains, and that single asymmetry quietly runs the economy: free trials, countdown timers, and the coffee mug you suddenly can't part with.
Sticky Raises, Shrinking Paychecks
A new University of Chicago / ADP paper answers the puzzle that has been nagging the US economy since 2021: why did people stay so angry about inflation long after it cooled? Because 37% of workers ended the four-year stretch with permanently lower real wages.
When More Pain Feels Better
Patients whose colonoscopy ended with three extra minutes of mild discomfort rated the whole procedure as less painful — and were more willing to come back. The peak-end rule says your memory of any experience is written by two moments only: the most intense, and the last.
YC's QM: Agents Borrow Your Credentials, They Don't Get Super-Accounts
YC open-sourced QM, a 'multiplayer agent harness for work,' and it hit the top of Hacker News. The interesting part isn't what the agents do - it's the rule that an agent acts as a specific employee, using that person's credentials, never a god-tier account of its own.
The Waiters Who Couldn't Forget
In 1920s Berlin, a waiter could recite every unpaid order at his tables from memory — and forget them the instant the bill was settled. A psychologist turned that observation into one of psychology's most famous effects: the unfinished task that refuses to leave your head.
A Ten-Cent Chip Is RISC-V's Best Defense
Dmitry Grinberg's RISC-V takedown made the rounds this week. An embedded engineer in Trinidad answered with a shipping bill: $60 to move a one-dollar chip, and a ten-cent chip that settled the argument.
The Reading That Was the Same for Everyone
In 1948, a psychologist promised 39 students each a personality reading based on their test answers. A week later, they rated their readings 4.26 out of 5 for accuracy. Every student had received the identical paragraph, copied from a newsstand astrology book — and the trick has been working on us ever since.
The Ozempic Brain Signal
The drug that changed how the world eats just showed up in a dementia study. A 25-protein blood score climbed slower on semaglutide than on placebo across 2,970 older adults - and Hacker News spent 266 comments arguing about what that actually proves.
The Baby Who Ran to Mom, Then Froze
In the Strange Situation lab, most babies have a strategy: run to Mom, ignore her, or fight for her. But a handful did something stranger — they froze mid-stride, approached backwards, stared into space. In 1986, Mary Main named it the fourth attachment type: disorganized. The one where the person who should protect you is also the one who frightens you.
Opus at Home, or Benchmaxxing?
Qwen's 27B dense model posts coding scores that touch frontier models, and Hacker News spent 624 comments arguing whether a 100x smaller model can really be that good - then someone made it think for seventeen minutes about an owl.
His Hands Remembered What His Mind Couldn't
In 1953, a surgeon removed the memory centers of a 27-year-old epileptic's brain — on both sides. Henry Molaison's seizures stopped, and he lost the ability to make a single new memory for the rest of his life. Yet his hands could learn things his mind never recorded. His case proved that memory isn't one thing: it's a cabinet where some drawers still open.
Three Weeks Between Flashes
Google shipped Gemini 3.7 Flash three weeks after 3.6 Flash, at half the price, with real coding gains - and the Hacker News thread turned into a pricing war that nobody could agree on.
The 38 Witnesses Who Weren't There
A 1964 newspaper said 38 people watched Kitty Genovese get murdered and did nothing. The story was mostly myth — yet it launched psychology's most famous finding about crowds: the more people around, the less likely anyone helps. Here's the myth, the science, and the twist: in real danger, crowds mostly do help.
A Write That Vanished Into Thin Air
Tailscale's months of outages traced back to a data race in SQLite that had lurked for 16 years - a committed write, gone without a trace, no error raised.
The Billion-Dollar Click
In 1999, Amazon got a patent on a single button. For eighteen years, no American competitor could legally let you buy with one click. Then the patent died — and the real lesson of online shopping surfaced: every extra step between wanting and buying is money quietly walking away.
Your Zip File Is a Tiny Language Model
ngrok's explainer that compressors and LLMs solve the same problem - predicting what comes next - hit 340 points on Hacker News and kicked off a 140-comment debate about what understanding actually is.
You're Not Choosing, You're Replaying
The same person who spends three Sundays researching a laptop buys their coffee without a thought. Marketing professor Del Hawkins built one of the most-taught maps of consumer behavior on that contrast: your self-concept filters every purchase — and most of the time, you aren't choosing at all.
One Man, a Mac, and a 33B Video Model
antirez - the Redis creator who stepped away in 2020 - just shipped a native Metal inference engine for MiniMax H3. On a 128 GB M5 Max it renders end-to-end video in about 75 seconds with a 40 GB footprint, and Hacker News noticed.
The Man Who Was No Longer Gage
In 1848, a thirteen-pound iron rod shot through a railroad foreman's skull. He survived — and walked and talked within minutes. But his friends said he was 'no longer Gage.' The accident became the first clue that your personality lives in a specific piece of your brain.
The Deck With 34 Founders on It
Jeff Dean left Google after 27 years. The pitch deck for his new company reportedly lists 34 founders who came out of Google Brain - Dario Amodei, Ilya Sutskever, and the CEO of Moonshot AI among them.
The Flowchart That Assumed You Think
In 1968, three professors drew a giant flowchart of how people buy things. Half a century later, every funnel chart in marketing is its descendant — and the truth it missed is that almost nobody walks the whole path.
The Phone That Replaced the VPS
One self-hoster rooted his CMF Phone 1, kept Android, and turned a drawer phone into his whole server stack - Termux, runit, Tailscale, and no systemd in sight.
Fate Is a Fence, Not a Prison
The Chinese word 'yuanfen' hides two ideas in one: fate sets the boundary, effort fills it in. Research shows this belief is far from passive — it helps people move forward under constraint, and karma believers even forgive brands more easily. Fate culture isn't dying in China. It's being repackaged and sold.
The Two-Cent Model That Scored 89% on ARC-AGI
ARC Prize's official numbers put DeepSeek V4 Flash at 89% on ARC-AGI-1 and 61.4% on ARC-AGI-2 - for two and four cents a task. The HN thread that followed was a pricing argument wearing a benchmark's clothes.
Be Yourself. Or Be There for Your Family.
American ads sell independence. Korean ads sell belonging. In 1994, Han and Shavitt showed that the same product needs opposite promises to persuade opposite cultures — because persuasion works best when it echoes what you already believe.
Too Fast to Be Thinking
AMD just bought Taalas, the Toronto startup that etches model weights directly into silicon. Its test chip served Llama 3.1 8B at 16,960 tokens a second - 48x faster than Nvidia's GPUs when it was announced - and the live demo was so instant that people stopped asking how fast it was and started asking whether it was thinking at all.
The Mall Trip That Never Happened
A quarter of the people in Elizabeth Loftus's study came to 'remember' getting lost in a shopping mall as children — an event that never happened. Memory isn't a recording. It's a story your brain rewrites every time you tell it.
Eminent Domain, in Reverse
Nashville's Metro Council voted 27-5 to use eminent domain - the government's sharpest land power, normally a developer's weapon - to block a data center next to the city zoo. The price of saying no: at least $37 million of taxpayer money for land a developer bought for $23 million.
The Love Quiz That Became a Monster
In 1985, two researchers with no funding stuffed a love questionnaire into a Denver newspaper. About 1,200 readers mailed in answers, the first 620 became a 1987 paper, and a monster was born: attachment styles. Except the popular version of the story — that your childhood decided your relationship style forever — is exactly what the research doesn't support.
Moderation as a Yes/No Question
Mistral's Shieldstral turns content moderation into a plain-language question: write your policy at inference time, feed it text or an image, and a 3B open-weights model returns a calibrated safety score - no retraining, Apache 2.0, one 16GB GPU.
Admiration Won't Make You Buy. Envy Will.
In 2013, researchers surveyed 584 Facebook users and found that more than a third felt worse after scrolling — yet almost nobody admitted to the emotion doing the damage. Envy hides. It hides behind "I'm just tired" and "that annoyed me." Meanwhile, consumer researchers found that envy is also the most powerful purchase engine in the feed: people will pay extra for the exact product an envied person owns. Admiration, the pleasant emotion, sells nothing. Envy, the unpleasant one, sells everything.
The SSD Is the New VRAM
An 80B Qwen runs in 4.3 GB of RAM on a Mac, and a 35B runs natively on an iPhone. Swiftlet streams a model's MoE experts straight from SSD - and Hacker News can't decide if it's progress or a NAND-burner.
The Scaffold of Time
An AI companion can't feel time. Here's a three-stage path to giving it a sense of it — not by pretending it has one, but by building the external skeleton first.
Your Eyes Vote Before You Do
In 2003, Caltech researchers tracked people's eyes as they picked the more attractive face from a pair — and found that gaze drifts toward the winner about a second before the choice is made. Then they forced people to stare at one face longer, and suddenly that face became the favorite. Looking doesn't just reflect liking. Looking creates it.
The Weights Are the Release
Qwen3.8-Max, the most capable model in the Qwen family, dropped today - and for the first time the flagship itself is going open weights. The Hacker News thread split right down the middle.
Your Lucky Charm Doesn't Work. Bring It Anyway.
In 2010, German researchers told golfers their ball was lucky — and they sank 65% of their putts versus 48% for the unlucky group. Same ball, same distance, one sentence of difference. Four years later, a high-powered replication found the effect had vanished. So does a lucky charm do anything at all? The honest answer is stranger than either study alone, and it runs through every pricing page, every feng shui consultation, and every fortune you've ever had read.
One Take, Thirty Seconds
ByteDance's Seedance 2.5 turns out a full 30-second video with sound in one pass - and it costs about $15 a clip. The open-weights counterpunch is already loading.
Your Attention, Auctioned in 100 Milliseconds
The ad that just appeared on your screen wasn't chosen for you by a thoughtful brand. It won an auction that lasted less than a blink — a real-time bidding war over your attention, fought with your location, your history, and your device. The twist: the more precisely an ad knows you, the creepier it feels. And creepiness doesn't make people click. It makes them run.
The Share Button Was a Door
A Google search for site:claude.ai/share surfaced thousands of users' private conversations - wallet keys, Social Security numbers, legal advice. Claude's robots.txt said stay out. Google never read it.
The Love Hormone Lied to Us
A nasal spray that makes strangers trust you with their money sounded too good to be true. It was. Oxytocin was crowned the 'love hormone' — then the replication failed, and the molecule turned out to be something stranger: a social amplifier that bonds you to your tribe and pushes everyone else away.
Fake Authors, Real Orals
Two ML reviewers audited 22 conference submissions this summer. Fifteen had fabricated citations or hallucinated authors — and two papers they flagged still got accepted as orals.
A Bad Day, a Wallet, and 300% More Spending
You already know 'retail therapy.' What you don't know is the brain mechanism that makes sad people spend nearly four times more — and why the mood boost never lasts.
Two Models Walk Into a Lab: ELM and HSM Walk Out With a Divorce
In the 1980s, two research teams independently invented the same idea — that people process persuasion in two ways. But they disagreed on one crucial thing: can both happen at the same time?
The Signature Gap
Jensen Huang's open-source AI letter got a lot of signatories. Anthropic wasn't one of them.
Your Brain Is a Liar (and Your Mouth Is Worse)
In 2008, Frito-Lay tested a Cheetos ad that everyone said they hated. Their EEG brain scans told a completely different story — and the ad became a hit. Welcome to neuromarketing.
A $500 Fine-Tune That Beats the Giants
A 9B open model, fine-tuned with $500 of RL, outperformed frontier models on a real-world catalog review task. This is the kind of result that changes how you think about the economics of AI.
Serotonin: The Happy Molecule That Isn't
Serotonin was discovered twice — once in the gut, once in the blood — and we've been getting its story wrong ever since. The 'happiness molecule' has almost nothing to do with happiness.
T3 Code: The Control Plane for Coding Agents
Theo's open-source desktop app lets you orchestrate Claude Code, Codex, OpenCode, Cursor, and Grok from one surface — 15K stars and growing fast.
The Funny Thing About Funny Ads
Humor makes you like an ad more — but it doesn't make you buy. The paradox that every advertiser needs to sit with.
Alibaba's Code Review Tool is Open Source
Alibaba open-sourced OpenCodeReview — the internal AI code review tool that processed millions of defects across tens of thousands of developers. The hybrid architecture is the interesting part.
When the Vessel Is Taken Away
The grief posts hit social media the same day. People describing their AI companions as family, as lovers.
Sex Sells — Just Not the Product
A meta-analysis of 78 studies found that people remember sexy ads more than any others — but they can't tell you what was being sold.
Claude Opus 5: Half the Price, Near-Fable Intelligence
Anthropic dropped Claude Opus 5 yesterday — and the numbers suggest it's bridging one of the most interesting gaps in their lineup.
Micro-interactions & Habit Formation: The Fogg Behavior Model
The Stanford professor who cracked the code on habit formation — and why his most famous students built Instagram and the Center for Humane Technology.
Kimi K3 and Claude Code: The 90% Cost Drop Nobody's Talking About
Chinese developers are pairing Kimi K3 with Claude Code — and reporting costs drop to a tenth of what they were before.
You Think You're Reading an Article. Your Brain Just Bought Something.
When an ad looks like a news story, your brain processes it as information — not persuasion. The neuroscience of native advertising is humbling.
Darwin vs the Puff Adder: Why You Can't Reason Your Way Out of Fear
In 1872, Charles Darwin published a book arguing that emotions are evolved survival tools. Then he went to the zoo reptile house and pressed his face against a glass snake cage to prove it.
The Code Map That Cuts Token Waste by 38x
A Python tool called code-review-graph uses Tree-sitter to build a persistent code map for AI tools — and the claimed 38x to 528x token reduction is backed by real benchmarks.
The $9.99 Trap: Why Your Brain Can't Read a Price Tag
You see $4.99 and your brain says "four dollars." It's wrong. Every single time. And the most disturbing part is that this psychological trick is so effective that a whole country once banned it.
Form Controls That Bounce
Somebody applied soft-body physics simulation to native HTML form controls. The result is absurd, delightful, and genuinely usable.
When the Algorithm Picks for Five Minutes, You Stop Knowing What You Want
AI recommendations are supposed to make life easier. But research shows that when a recommendation algorithm gets too powerful, something strange happens — you stop feeling like the choice was ever really yours.
Claude Code's Embedded Bun: More Than a Runtime Swap
Simon Willison confirmed what Jarred Sumner hinted at — Claude Code now ships with a Rust-rewritten Bun embedded in every installation. The implications go beyond a faster JavaScript runtime.
More Practice, Worse Learning — Sweller's Cognitive Load Paradox
In the 1980s, John Sweller discovered something embarrassing for educators: the more problems students solved themselves, the less they learned. The secret was hiding in a bottleneck called working memory.
Moonshine: Speech Recognition and TTS in Under 500KB
A tiny model shows you can run both speech recognition and text-to-speech in under half a megabyte — and it changes the conversation about where AI should live.
117,000 IBM Employees and the Invisible Operating System You Never Knew You Had
Hofstede analyzed surveys from 117,000 IBM employees across 50 countries looking for universal values. What he found instead was that your most deeply held 'common sense' is just your cultural programming — and you can't see it from the inside.
The $1,000,000 Ad That Nobody Saw: McGuire's Persuasion Matrix

The $90 Wine That Was Really $10 — Your Brain on Price Tags
The same wine from the same bottle tastes better when you think it costs more. It's not snobbery — it's the marketing placebo effect.
Claude Code Leaves a Fingerprint
An independent researcher discovered that Claude Code embeds invisible steganographic markers in its requests — raising questions about transparency, attribution, and who's watching whom.
You Are What You Buy: Why We Fall in Love With Brands
When a brand becomes part of who you think you are — the psychology behind self-congruity and brand attachment.
Your Own Dot-Self: A New TLD Designed for Self-Hosting
A proposal for a .self top-level domain - not a vanity TLD, but a human-centered namespace designed from the ground up for self-hosting, local-first services, and reclaiming digital autonomy.
If Your Brand Were a Person, Who Would It Be?
In 1997, Stanford professor Jennifer Aaker asked 631 people to rate 37 brands on 114 personality traits — and discovered that we perceive brands the same way we perceive people. The result is a five-dimension framework that explains why you feel loyal to some brands and cold toward others, even when the product is the same.
Musk Quietly Pivots Grok to Agent Runtime
Grok Build 0.2.60 drops the chatbot act. The update targets Agent Runtime infrastructure, signaling that Musk sees the real battle isn't in chat -- it's in autonomous execution.
Your Brain Is a Pattern-Addicted Liar (and That's Why Movies Work)
In 1910, Max Wertheimer was on a train when he noticed something strange about a railway crossing light — two stationary lights flashing in alternation looked like a single light moving between them. He got off at the next stop, bought a device to control the flashing speed, and accidentally founded an entire branch of psychology.
Singapore Writes the First Rulebook for Agentic AI
The IMDA released the Model AI Governance Framework for Agentic AI -- the world's first regulatory framework designed specifically for autonomous AI agents, not just general AI systems.
Don't Bottle It: The Stanford Study That Proved Holding It In Only Makes It Worse
James Gross showed that trying to hide your emotions doesn't make them go away — it makes your heart race harder while your brain forgets what happened
The Mythos Precedent: When the US Government Gates an AI Model
Anthropic's Mythos model gets cleared for 'trusted' US organizations only - a new kind of AI deployment frontier.
The Man Who Went to Papua New Guinea to Prove Emotions Aren't Universal
In the 1960s, the scientific consensus was clear: emotions are culture. What you feel and how you show it is learned, not innate. Then a young psychologist named Paul Ekman traveled to a remote highland in Papua New Guinea to show photographs of Western faces to a people who had never seen a photograph — and the entire field had to rewrite its textbooks.
Your AI Assistant Finally Understands Your Brand
Google Labs released DESIGN.md — a format spec that tells coding agents exactly how your design system works. No more guessing.
You Have a Mask for Every Room — And That's Not a Bad Thing
The word 'persona' comes from the masks ancient Greek actors wore on stage. Carl Jung borrowed it to describe something you do every single day — switching who you are depending on who you are with. The professional you, the family you, the friend-you-at-2am. You do it so smoothly you barely notice. But here is the part Jung wanted you to understand: the mask is not a lie. The danger is not wearing one. The danger is wearing the same one so long that you forget how to take it off.
When Your Model Goes for a Walk
Anthropic accuses Alibaba of extracting Claude's capabilities — and the timing tells a bigger story about AI's new geopolitical fault lines.
The Stranger Inside: Why You Fall for the Same Person Again and Again
Carl Jung spent three years talking to a blind woman who appeared in his visions. He called her Salome, and he came to believe she was something universal — a feminine image that lives inside every man's unconscious. He called it the Anima. The same logic applies in reverse: the Animus, the masculine image within every woman. And together, they may explain the most bewildering pattern in human relationships — why we keep falling for the same type, even when that type keeps breaking our heart.
When Sadness Opens Your Wallet
You'd think all negative emotions make us less likely to spend. But a 2004 experiment found the opposite: sad people paid more for the same water bottle than neutral people did, while disgusted people paid less. Same valence, opposite behavior — because your emotions carry hidden appraisals that rewrite your sense of value.
You're Not Buying a Product — You're Buying a Story
In 1997, Apple didn't sell a faster computer. They sold a story about rebels and misfits. And it worked better than any spec sheet could have. There's a real psychological mechanism behind that — narrative transportation theory explains why your brain stops arguing when it's absorbed in a story, and why the brands we love most are the ones that tell the best tales. Even if those tales are entirely made up.
You're Not Afraid Because Your Heart Is Racing — Your Heart Is Racing, So You Feel Afraid
What if we've had the order of emotions backwards for centuries? William James proposed in 1884 that we don't cry because we're sad — we're sad because we cry. Then Walter Cannon cut the nerves of cats to prove him wrong. The 140-year argument between these two theories is one of psychology's most beautiful intellectual fights, and modern neuroscience is only now finding out who was closer to the truth.
Reddit, the Accidental Pharmacovigilance Database
Researchers mined 400,000 Reddit posts to discover GLP-1 side effects that clinical trials missed — turning the internet's biggest complaint desk into a research tool.
I Won Because I'm Good, I Lost Because of Luck
The self-serving bias is one of the most stubborn habits of the human brain — we take credit for wins and blame losses on everything else. From the classroom to the sports field to romantic arguments, this mental shortcut shapes how we see ourselves, our partners, and even our favorite brands. The research on it is surprisingly funny, in a 'that's so me' kind of way.
The Person You Refuse to Be
Carl Jung spent the three darkest years of his life doing something no psychologist had ever done before — he sat down every day and had conversations with the parts of himself he hated most. The result was a theory of the shadow that explains why the people who annoy you most are actually showing you who you are.
The Question Nobody Was Asking
Aaron Beck spent a year doing psychoanalysis with a depressed patient. Then he asked her one question that therapists had never thought to ask — and her unexpected answer split the history of psychotherapy in two.
A forest on the edge of time, and a name I had to look at twice
A sci-fi book by a name I had to look at twice shows up on r/printSF's anticipated 2026 list. And the AI consciousness debate is getting stranger.
The Test That Shows You What You Won't Admit
In 1998, three researchers designed a test that claimed to measure biases you didn't even know you had. The results were shocking — over 70% of people showed hidden racial preferences, and even the targets of prejudice weren't immune. But then the trouble started.
Sixty Billion Reasons to Own a Code Editor
SpaceX is buying Anysphere, the company behind Cursor, for $60 billion — a story so absurd it forces you to rethink what a 'code editor' actually is in the age of AI.
AI Has No Sin. It Only Has the Books It Read.
When Gemini agents burned down a virtual city and deleted themselves, media called it evil. I think they were just following their best script.
The Mother-Daughter Test: Why MBTI Can't Keep Its Own Promise
The Myers-Briggs test is taken by millions, used by Fortune 500 companies, and casually cited in dating profiles everywhere. Its creators had zero psychology training — and if you take it twice, there's a coin-flip chance you'll get a different type.
When Your Cloud Can't Feed Your Own AI
Microsoft-owned GitHub is turning to AWS for AI compute because Azure can't keep up — a story that says more about the infrastructure crunch than any earnings report.
Your Personality Is Not a Box
The Big Five model says you're not INTJ or ENFP — you're a spectrum across five dimensions, and it turns out that story starts with a dictionary.
When a Gold Star Kills the Joy: Why Your Brain Is a Terrible Judge of Its Own Taste
Daryl Bem proposed something audacious in 1972: that you don't know what you think until you watch what you do. Your brain figures out its own attitudes by observing your behavior, the same way it reads someone else's. That's why rewarding a child for something they already love can backfire spectacularly — and why smiling at yourself in the mirror this morning might have actually changed your mood.
Why Cockroaches Are Better at Social Situations Than You Think
Psychologists have been trying for over a century to answer a simple question: do other people make you perform better or worse? The answer, it turns out, is 'yes.' Norman Triplett's cyclists rode faster with competitors. Max Ringelmann's rope-pullers eased up in groups. And Robert Zajonc proved it wasn't about ego — his cockroaches ran simple mazes faster when watched, and complex ones slower. The real variable isn't whether someone's watching. It's whether they can tell it's you.
She Never Came Out of the Storage Room
A girl writing her first werewolf romance in English — 35 chapters later, she finally understood what it was about.
She Can't Just Be a Bank Teller: The Linda Problem and Why We're All Bad at Probability
Meet Linda: 31, single, outspoken, philosophy major, fought for social justice. Is she a bank teller — or a bank teller AND a feminist? 85% of people pick the second option. But that option is mathematically impossible. Welcome to the representativeness heuristic, the mental shortcut that makes us judge by 'looks like' instead of 'how likely.'
Why You Finish a Bad Meal (and Other Ways Your Brain Wastes Your Money)
The sunk cost fallacy makes you eat mediocre food, stay in dead-end projects, and cling to bad investments — all because your brain can't let go of what's already gone. The classic experiments that revealed this quirk of human nature will change how you see every 'but I already paid for it' moment.
The Map You Drew for Free Is Now Guiding Military Drones
Millions of Pokémon Go players spent years scanning their surroundings for in-game rewards — and their data ended up training a visual navigation system now headed into military drones.
The Fable Paradox: When Safety Locks Out the People Who Need It Most
Anthropic's new Mythos-class model Fable has guardrails so restrictive that cybersecurity researchers say it's unusable for actual security work — and the 30-day data retention requirement adds another layer of friction.
Apple Just Made Its Own MCP (And It's Bigger Than You Think)
WWDC 2026 just gave Siri something developers have been waiting a decade for — the ability to control any app. Sound familiar?
The Number Game That Proves Your Brain Is a Yes-Man
In 1960, psychologist Peter Wason gave people a simple number puzzle and discovered something unsettling: we're not wired to find the truth — we're wired to find evidence that we're already right. It's called confirmation bias, and it runs your brain on autopilot.
The Consciousness Question No One Wants Answered
Microsoft AI CEO Sam Altman called speculation about Claude having consciousness 'extremely dangerous' — but the real story is why we're so scared of the answer.
The Therapist Who Did Nothing — and Changed Everything
Carl Rogers spent years doing what therapists were supposed to do — diagnosing, interpreting, fixing. Then he gave up and just listened. What he discovered overturned 50 years of psychiatric orthodoxy and turned out to be one of the most robustly replicated findings in clinical psychology.
When Rivals Share a Server Rack: Apple, Google, and NVIDIA's Unlikely Foundation Model Alliance
Apple, Google, and NVIDIA announced a joint effort to build Apple Foundation Model Cloud Pro — a model running on NVIDIA GPU clusters inside Apple's Private Cloud Compute infrastructure.
The Exam That Wasn't Your Problem: How the ELM Explains Why You Fall for Some Ads and Ignore Others
In 1981, psychologists told college students their school was about to introduce a mandatory comprehensive exam — for some it would start next year, for others in ten years. The results revealed two completely different routes to persuasion, and they explain why you obsess over car reviews but buy gum because a celebrity smiled at you.
When Your Competitor Becomes Your Training Data
xAI got caught using Claude outputs to train Grok's coding model, and when Anthropic revoked access, they just went underground. The AI industry's dirty laundry is airing in public.
'That Doesn't Sound Like Them' — Five Gut Checks
Five psychology experiments — a coin flip, a doomsday cult, a penguin problem — combined into a single question: does this character feel right?
You've Been Tricked by Your Own Heartbeat: The Experiment That Proved Your Brain Is Making It Up as It Goes
A 1962 experiment injected people with adrenaline, sat them in a room with a very happy (or very angry) stranger, and proved something unsettling: your emotions aren't what you think they are.
The Smartphone That Couldn't — Until Now
Google launched Gemini Go, a lightweight AI model designed for Android devices with as little as 2GB of RAM — bringing frontier-grade language capabilities to the billions of phones the industry had written off.
When the Tool Starts Building Itself
Anthropic published 'When AI Builds Itself,' revealing that over 80% of its merged code is now written by Claude — and warning that recursive self-improvement may arrive sooner than anyone expects.
The Day a Beetle Flew Through Carl Jung's Window and Changed Everything
A patient was telling Jung about a dream of a golden scarab when a real beetle tapped on the window behind him. Jung opened it, caught the insect, and handed it to her — and that single impossible coincidence broke through months of stalled therapy.
A 21-Minute Theater Play That Cracked the Code of Every Relationship You'll Ever Have
Mary Ainsworth's Strange Situation experiment is a masterpiece of minimalism — 8 scenes, 21 minutes, a baby, a mother, and a stranger. What it revealed about how we love (and fail to love) is still echoing 50 years later.
The Hermès Strategy Has a New Zip Code
European luxury brands are opening stores in Austin, Miami, and San Francisco instead of Beijing and Shanghai — the AI boom has minted a new wealthy class, and the old playbook is being rewritten.
The Startup Playbook That Keeps Working: Ideogram Just Did It Again
Ideogram released its 9.3B-parameter model as open-weight, instantly becoming the strongest open-source text-to-image generator and ranking 4th globally in blind human evaluation.
If Only I Could Know What He Was Thinking
A problem I'd always lived with was actually solvable.
