Sample Facts from the BrainSmut Archive
Weird Science
Octopuses on MDMA hug longer and prefer to hang out in the open instead of hiding. Scientists now think loneliness might just be a chemical setting evolution forgot to optimize.
A teaspoon of neutron star matter weighs as much as Mount Everest. These stellar corpses spin up to 700 times per second, beaming X-rays like cosmic lighthouses.
Bananas glow with potassium-40 decay — 0.1 microsieverts per fruit, enough to ping airport scanners in truckloads.
Forbidden History
In medieval Iceland, if you insulted someone's poetry you could legally be killed. Duels were fought with rhymes instead of swords.
The shortest war in history was between Britain and Zanzibar in 1896. Zanzibar surrendered after 38 minutes.
In 1932, Australia declared war on emus. The emus won. Armed with Lewis guns and 10,000 rounds of ammunition, soldiers managed to kill only a fraction.
Psychology Smut
When you remember a memory, you're actually remembering the last time you remembered it. Every recall slightly rewrites the file. Your childhood is not what you think it is.
The 'doorway effect' — forgetting why you walked into a room — happens because your brain treats doorways as event boundaries.
Your brain cannot tell the difference between remembering something and imagining it. The same circuits fire for both. False memories feel exactly as real.
Corporate Evil
In 1924, the world's biggest lightbulb makers — GE, Philips, Osram — met in Geneva to commit a corporate crime. They formed the Phoebus Cartel and agreed to make bulbs burn out faster.
Infrastructure Horror
The global internet isn't in the cloud — it's in garden-hose-sized tubes on the ocean floor. Sharks are biologically attracted to the electromagnetic fields.
If you feel a 'presence' in a dark room, you might not be seeing a ghost — you're hearing an exhaust fan. Infrasound at exactly 18.98 Hz vibrates the human eyeball.
IKEA stores are designed to induce a specific neurological state. By removing windows, using uniform lighting, and creating a labyrinthine fixed path.
Unknown Genius
Srinivasa Ramanujan taught himself mathematics from a single outdated textbook in colonial India, then mailed his theorems to Cambridge.
Henrietta Lacks was a Black tobacco farmer whose cancer cells were taken without consent in 1951. Those cells — HeLa — became the first immortal human cell line.
Existential Vertigo
In Utah, there's a 'forest' of 47,000 quaking aspens called Pando. The twist: it's not a forest. It's one single male tree with a massive interconnected root system.
Our entire galaxy is being hunted. The Milky Way, along with 100,000 other galaxies, is currently being pulled toward a mysterious gravitational anomaly called the Great Attractor.
Every grain of sand from every beach and desert on Earth adds up to roughly 7.5 quintillion grains. Sounds like a lot until you look up. There are approximately 70 thousand million million million stars.
Deep Sea Horrors
Off the coast of South Africa, two orcas named Port and Starboard have single-handedly collapsed the local Great White shark population.
In the midnight zone, the male Pacific Footballfish is the size of a quarter. The female is a six-inch beast with a glowing lure.
Biological Agency
Around 2 billion humans carry a brain parasite called Toxoplasma gondii. Famous for making mice lose their fear of cats.
You are not entirely human. Roughly 8% of your DNA is made of 'Endogenous Retroviruses' — leftovers from ancient viral infections that hijacked our ancestors' genomes.
Bizarre Historical Fashion
Victorian "it girls" wanted a ghostly, translucent pallor — proof they were too wealthy to work in the sun. To achieve it, they consumed arsenic wafers.
Venetian chopines were wooden or cork platforms up to 20 inches tall — not shoes, mobile pedestals. The height directly correlated to social status.
The Case for Good Addictions
Aristotle might not have built any apps, but if he had, I think he would have understood BrainSmut immediately.
Eudaimonia — human flourishing — was never, for Aristotle, a matter of willpower. It was a matter of habituation. We become what we repeatedly do. Virtue is not chosen once in a moment of moral clarity; it is accumulated through daily practice, through the slow layering of repeated actions into something we eventually call character.
Most educational technology ignores this completely.
We pretend that learning happens because people "value knowledge" — that the desire to improve is sufficient motivation, that information is medicine taken willingly for one's own good. This model doesn't describe human behavior, and it never has.
People check their phones hundreds of times a day not because they love trivia, but because novelty, anticipation, and reward are wired into the nervous system. The same cognitive machinery that narrows a life can also expand one. The question is never whether we will form habits. It is which habits we will form — and what they will train us to love.
BrainSmut is an experiment in redirecting that machinery.
It delivers one rigorously sourced, genuinely surprising idea per day. No feed. No scroll. No algorithmic flood. Then it stops you. You get one idea and are told no.
That limit is the product's ethical center. Desire is acknowledged, not shamed. Craving is allowed to arise — and then trained to wait. This is not accidental design. It is the philosophical premise made functional.
The facts themselves are not motivational posters. They are strange, rigorous, sometimes unsettling truths drawn from real scholarship, visibly sourced, written to land with force. The pleasure is genuine. So is the work being done.
I am a literary scholar who spent twenty years teaching at Yale and The New School. I believe attention is the fundamental human resource — more scarce, more valuable, and more trainable than most people realize. I build apps because I think the design of daily habits is the highest-leverage intervention available to anyone interested in human flourishing.
BrainSmut does not promise self-improvement. It offers something more honest: a daily practice of active wonder, one idea at a time, in a world engineered to keep you passive.
Ideas are addictive. Let's make that work for us.
