The Strange Hobby of Collecting Facts

Somewhere between the person who memorizes sports stats and the one who can recite Shakespeare, there’s a third species: the trivia hoarder. These are the people who know that octopuses have three hearts, that the shortest war in history lasted 38 minutes, and that the inventor of the Pringles can is buried in one. They’re the friends you text at midnight to settle a bet. They’re also, occasionally, wrong — and that’s the real story here.

Collecting fun facts is a genuine hobby with a surprising amount of craft behind it. Done poorly, you become the person confidently telling everyone at dinner that humans swallow eight spiders a year in their sleep (they don’t — that claim was literally invented in a 1993 magazine article to prove how gullible people were). Done well, you become the kind of storyteller people actually want to sit next to. The difference is all in the sourcing.

Why So Many Famous Facts Are Wrong

The frustrating truth about viral trivia is that roughly half of it falls apart under the slightest scrutiny. The “we only use 10% of our brain” claim has been repeated so often it’s become cultural wallpaper, but neurologists will tell you we use virtually all of it, just not all at once. Brain imaging lights up different regions for different tasks, and a brain that was 90% idle would have been evolutionary dead weight. The myth likely traces back to misquoted psychologists from the early 1900s, possibly tangled up with a Dale Carnegie book foreword.

Napoleon wasn’t short — he was about 5'7", average for a Frenchman of his era. The misconception came from British propaganda and a confusion between French inches and English inches. Vikings didn’t wear horned helmets; that was a 19th-century opera costume designer’s invention. Bulls aren’t enraged by the color red, since cattle are red-green colorblind and respond to motion, not hue. The Great Wall of China isn’t visible from space with the naked eye, despite what your third-grade textbook swore. Even Einstein didn’t actually fail math — he had largely mastered calculus by fifteen.

The pattern here is clear. Facts that sound satisfying spread faster than facts that are true. Our brains reward narrative elegance over accuracy, which is exactly why you need a system.

Where the Good Stuff Lives

The gold standard for trivia enthusiasts is QI — the British panel show Quite Interesting — which employs full-time researchers called the QI Elves who fact-check everything to an almost religious degree. Their weekly podcast, No Such Thing As A Fish, is essentially a dispatch from people who do this for a living. When the Elves say something, it has been through several rounds of verification.

For myth-busting specifically, Snopes remains the workhorse, although it’s been joined by solid contenders like Reuters Fact Check and the Poynter Institute’s network. Academic sources beat pop science nine times out of ten — Google Scholar, JSTOR if you have access, and the reference sections of good Wikipedia articles (Wikipedia itself is fine as a starting point, terrible as an ending point). Museum websites are underrated troves. The Smithsonian and the British Museum publish genuinely careful material written by curators who would rather die than get a date wrong.

Atlas Obscura leans more toward odd places than odd facts, but their editorial standards are solid. Damn Interesting, an older blog, has some of the best long-form trivia writing on the internet, each piece sourced like a term paper. And Radiolab episodes regularly produce the kind of strange-but-true stories that age well.

A Few Facts Worth Your Time

Here’s one that survives scrutiny: honey genuinely does not spoil. Archaeologists have found edible honey in Egyptian tombs dating back over 3,000 years. Its low moisture content and acidic pH create an environment hostile to microbes, and bees add an enzyme that produces hydrogen peroxide as a preservative.

Another keeper: the platypus is one of the only mammals that produces venom, but only the males, and only through spurs on their hind legs. The venom can cause excruciating pain in humans that reportedly doesn’t respond well to standard painkillers.

Wombats produce cube-shaped droppings — actually cubic, with flat sides — because of the unusual elastic properties of the final section of their intestines. Scientists only figured out the mechanism in 2018, and it’s now being studied for industrial applications.

And here’s a personal favorite: the dot over a lowercase i or j has a name. It’s called a tittle. Which means when someone says “not one jot or tittle,” they’re being extremely literal about punctuation marks.

How to Tell a Fact Without Being That Guy

A well-delivered fun fact lands softly and invites conversation. A badly delivered one is a small monologue nobody asked for. The trick is letting the fact earn its place in the conversation rather than wedging it in. If someone mentions they had a bad sleep, that’s not the moment to announce something about koalas sleeping twenty hours a day. That’s the moment to listen.

Short is better than long. Concrete is better than abstract. Surprising is better than impressive. The fact should do the work — you shouldn’t have to sell it. And crucially, know your sourcing well enough that when someone pushes back (“really?”), you can say where you read it instead of mumbling “I think I saw it somewhere.” That mumble is what separates the trivia hoarder from the trivia curator.

Building a Collection That Sticks

The facts that stay with you tend to be the ones that connected to something else — a story you were already telling yourself, a question you’d quietly wondered about, a category you cared about. This is why rote memorization fails and why passionate specialists outperform generalists in their lane. A bird person will remember that crows hold grudges and can pass them down to other crows, because that fact plugs into a thousand other things they already know.

Keep a notes app or a physical notebook. Write down the fact, the source, and the date. Re-read it occasionally. Resist the urge to hoard quantity over quality — thirty well-sourced oddities you can explain in two sentences will serve you better than three hundred half-remembered factoids. A fact you can’t defend is just a rumor with a haircut.

The real pleasure isn’t the collecting. It’s discovering, somewhere down the line, that the world is weirder than the version of it you’d been handed.
