“Almost Frightening”: 47 People With Little To No Education Who Redefined Intelligence

When I was a kid in the 50s-60s the neighbor across the street was a genius. He had an eidetic memory. Whatever he read, saw or heard he vividly remembered. He was like a living Wikipedia.

He was self taught in electronics and mechanical engineering. He worked on the development of control systems in helicopters during the war. He worked on the guidance system for the Nautilus Submarine that traveled under the north pole. He worked on the development of the original hard drive memory. He developed machinery that created synthetic gemstones. His last job was creating plotters for computers and CNC for machinery.

His workshop was something from Mr. Wizard's workshop. He was an incredible metal and woodworker. He was curious about everything. He was amazingly generous with his time. If I had a project as a kid he was always willing to help but never take over and do it. I was a lucky kid to know him.

I've met brilliant uneducated homeless people. Mental health is an issue for many top minds.

I did customer service management at a grocery store. There was a job coach named Nichole. She worked with the mentally disabled coworkers we had. She had never been to college and had to quit high school due to her family’s hard living. We all talked and she often talked to customers/bosses/higher up bosses that would come in. 

She is one of the most intelligent people on the planet. She could listen to any situation, carefully consider it, and approach it not only in a wildly efficient way but also with consideration on how people would react, the potential issues that would arise, and situations that would make it better or worse. But she would do this in like 10 seconds. And she would relay this information in the most understanding, kind, calm, and clear way. It was just astounding. 

She could effortlessly navigate issues with kids or parents or coworkers or bosses, literally anyone, while somehow finding the most rational and compassionate answers. She can take someone at a 10 on the angry scale and take it to a zero without them even noticing. 

I don’t work there anymore but I see her sometimes. And to this day even her presence is calming and secure. 

Her emotional intelligence is almost frightening. 

And it spills into her personal life. She got married super young and had been married 40 years. They have 6 kids who are all awesome, polite, smart, and successful and they love each other. Her husband and her are relationship goals. Her great grandma lives near me and you can tell Nichole is keeping everyone connected. 

Listening to her is like listening to a self-help podcast but even more effortless. Knowing her is a gift. 

It’s a different kind of genius but wild to experience.

Nikola Tesla praised his mother Djuka as true genius. She was illiterate peasant, married to an Orthodox priest in 19th century, in a rugged remote area. She was a weaver and was famous for being able to make super complex patterns without any plan or draft. She was also making water mills and various useful devices powered by her water mills. It seems that Tesla got his phenomenal visualisation and inventiveness from his mother and brought it many levels up. She was also very supportive of him studying engineering, while his father wanted him to become a priest. Makes you wonder what mark would she make on the world if she had more opportunities.

A mechanic I worked with when I was 19. Guy looked like he hadn’t read a book since primary school. Never went to high school. He could barely spell half of the tools he used. But his mind worked like a forensic computer.

Once, a customer brought in a car that 3 CERTIFIED technicians had already failed to diagnose. He didn’t touch anything, just listened to the engine for less than 10s, tapped the hood twice and said “this thing has maybe 48 hours before something in the timing system tears itself apart.”

Everyone laughed at him. 2 days later, the customer called: the chain snapped in the highway, exactly like he predicted.

His education was 0, but his pattern-recognition was TERRIFYING. He could predict failure, spot lies, read people’s intentions and build things that no hone taught him.

He went from not knowing a word of Spanish to be a fluent Spanish speaker in 1 month.

Never met someone like that again.

My mother. Born in 1930, did get some secretarial schooling after high school. Was somehow one of the first computer specialists in existence for the Air Force among other brilliant characteristics.

My father, he dropped out of high school and worked construction. Absolutely the smartest person I knew, he read all the time and complicated math so fast. When he got sick with a rare disease, he worked with his doctors on treatment plans, studied medical journals and research papers. He went from 6 months to live to surviving over 10 years. He was also extremely charismatic, made friends where ever he went. I wish I could be half the father he was to me.

I worked with a man who could calculate stress fractures in concrete beams faster than our $20,000 engineering software.

He was a foreman on a major bridge construction project, about 60 years old, and hadn't finished high school. Let's call him Frank.

Frank couldn't read a blueprint in the technical sense- he'd look at the symbols and dimensions and translate them into a sort of mental 3D model. Our team had several structural engineers with advanced degrees.

The moment of genius came when we were pouring a new approach ramp. The computer models were indicating a slight, almost negligible, risk of shear failure at a specific joint. The engineers started arguing about which variables to re-input for several hours.

Frank walked over, didn't touch the computer, and just looked at the rebar cages. He took a piece of chalk, scribbled maybe four or five quick, messy calculations on a nearby pile of plywood, and said: "The distribution on that lower cage is off by 1.8 degrees on the main line. You've got an asymmetrical load path. You need three more stirrups here," and he tapped a spot.

We re-ran the *entire* complex model using his suggestion- not just his fix, but his initial assessment of the error. He was exactly right. The software confirmed the asymmetry, and his quick chalk fix stabilized the structure perfectly.

He didn't know the names of the formulas he was using. He didn't know about tensors or eigenvalues. He just intuitively saw the physics in a way the highly educated people couldn't. It wasn't math for him; it was vision.

It taught me that formal education gives you the language to describe the universe, but genius gives you the native fluency to speak it.

I know a senior reactor operator who is one of the smartest guys I’ve ever known but couldn’t get through college. The number of people who are smart enough to become senior reactor operators is incredibly small. I am close with someone who is a pediatric neurosurgeon, a professor at duke with a phd in physics, several people with phds in microbiology, a vet, am surrounded by engineers, and my best friend works for the UN. This describes my inner circle and seriously this guy is so much smarter. We have been friends since I was in High school and he was one of the “gifted kids” but even being one you can tell some of them are significantly more brilliant than others. All that to say education isn’t something I’d use to measure intelligence. Intuitive types are often penalized by formal schooling where sensors tend to be rewarded.

My dad. Finished school in grade 8. Worked to contribute to the family. Was in Europe for 3 years during WW2. Learned 5 languages fluently. Could figure out any problem and had dizzying critical thinking skills. Always had a passion for curiousity and always, always asked great questions, and was able to sum things up with brilliant, nuanced insight.

He was and always will be, the genius I look up to.

I had a Sgt in the Marine Corps who was a Mechanic and that guy was brilliant. Could fix aaannytthhiinngg. Trace down wires into circuit boards and find it was a singular loose pin in a connector or something. The guy was just on another level next to all of us mouth breathing crayon eaters.

One time he came up with a way to patch bullet holes in the side of a fuel truck on the fly. Pounding a bolt wrapped in a mechanic rag with some silicone into the hole to stop the spill.

He also was a hell of a leader and knew what buttons to push to get the best outa his guys. Lucky to have known that guy.

I’ve met a few. They don’t always sound educated, but they think in ways that surprise you. They learn fast just by watching, solve problems instantly, and make connections others miss.

One guy I knew never finished school but could diagnose and fix any machine just by looking at it. The trained engineers argued with him, and he was right every time.

Genius doesn’t always come from classrooms. Sometimes it comes from life.

My late boyfriend of 12 years. He passed away in 2022 at age 61. He says he barely graduated high school - according to him, his teachers liked him, he was a popular jock in a popular band, and he got away with not doing much schoolwork at his small-town high school (it was the '70s, and apparently it was easier to get away with stuff back then). After graduating, he became a semi-successful hair metal singer in the '80s in L.A. I can state with a good deal of certainty that you've never heard of him, but he made enough money to get a house and pay his bandmates and road crew. He was a fantastic singer and songwriter, but he readily admits that he got to where he did because he was good-looking.

He liked to claim that he was a dumb uneducated hillbilly. But he was like Rain Man with remembering sports statistics, players, teams, records - if it happened in the NBA or Ohio State football in the '60s through the '90s, he could rattle off astonishing data dumps of facts. He claimed that the only book he'd ever read was Ric Flair's autobiography, so I bought him the autobiography of one of his favorite NBA players, Celtics great Bill Russell. He devoured it in two days. So I bought him another, and another - once I ran out of Celtics books, I moved on to his favorite musicians, other sports figures. Anything he expressed interest in, I bought him the book if there was one. Slowly, our library shelves became lined with books, and 90% of them were his. He didn't like fiction, and it had to be subjects he was interested in, but within those parameters, he was frighteningly well-read. I'd often find him in the evenings with his "dumb hillbilly" nose buried in a book.

He could do math in his head - I'm good at math, but if I needed to calculate a tip, or ask how much the sale price of something was, asking him was quicker than getting out my phone calculator. He never took algebra, so that's where his knowledge stopped, but it was crazy how fast he could calculate simple math problems.

I work with the English language for a living, and I'm a really good speller. He claimed he was a terrible speller - but whenever he made spelling mistakes, the mistakes made sense. Often the English language doesn't make much sense, and I had to convince him that it's the English language that's wrong, not him. He had an intuitive sense for phonetics that I rarely see.

His songwriting showed his brilliance. His lyrics didn't always make sense; he put the words where he thought they sounded good. It was like he was sculpting a soundscape using words. He had a knack for writing catchy melodies - I've met a lot of musicians, but never one who could write songs that were that good, let alone write them so effortlessly.

One thing I noticed was his curiosity. He'd ask questions if he didn't know about something. He'd never voted til I came along; our first election together, I helped him register, and he asked tons of questions about each candidate.

He was truly one of the most fascinating, entertaining, intelligent people I've ever met, and I miss him every day. I told him he was one of the smartest people I've ever met, and he'd laugh, but it's true.

I have a friend named Shawn.

Shawn grew up in a tiny redneck town with a redneck family and went to a redneck school. Nobody in his immediate circle saw how smart he was, so his innate problem solving and intuition and curiosity went to waste.

He's like a one-man Mythbusters team. One of his friends got a fishing boat stuck in mud after leaving it out for a week in a dried pond. They tried everything to dislodge it. And these are not dumb people, they're pretty smart, but he came along and grabbed a piece of paper and was able to design a pulley and winch system that allowed three cars to pull it out. I had never seen anything like it, but it worked, and it was super efficient.

He likes to fish. He collected publicly available data from the local fish and wildlife website and designed a python script to figure out where on his calendar to put certain rivers and lakes. Thing is, he doesn't know python. He basically sketched out the formula and then asked me to make it "into an app or something" but it was already done. It was incredible.

Talking to him you'd think he went to Harvard or at least UCLA — he's informed on the world, has a great sense of how things connect that are surprising but is usually right, and just talking to him you can tell his youth was wasted on dirt bikes and firecrackers.

He's a high school dropout but runs a very successful drywalling business where he has a staff of 14 and does it all in his head. We've tried to get him at least to use Quickbooks, but he says it slows him down.

If he had gone to school and learned how to use better critical thinking and how to harness his intellectual curiosity he'd be an industry giant. But he lives in a tiny one-bedroom apartment, fixes dirt bikes as a hobby, and prospects gold.

My brother! I’m always thought of as the one who has it together. I have a bachelors degree (which given how we grew up is no small feat), a corporate job, etc. But he is smarter than me by a country mile, school was just never his thing. He barely finished high school. I just don’t think he learns things the way they want kids to in school. The way his mind works astonishes me every time. He is so insightful and makes leaps in his thinking that I would never think of, not in a million years.

I’m in awe of him, I really am. My little brother is amazing.

An uneducated genius is someone who can solve problems you didn't even know existed - but can't explain how they did it in academic language.

They think in connections instead of rules.
They learn by observation instead of instruction.
They understand before being taught.

My wife. She grew up really, really poor. She spent most of her childhood in the woods. And I mean that literally. She’s reluctant to speak of how she grew up, but over the course of 20 years I’ve managed to piece together how it was. And hell was it bleak.

She’s an actual genius. Not only is she incredibly intelligent (she’s been tested several times), but she is a one of a kind artist. She can pick up anything and then improve on the process. I’ve seen this so many times. Music, art, mechanics, carpentry, metalworking. She knows more about nature than any other person I’ve met. Also the funniest person I’ve ever met. Adored by all.

Most people don’t really understand just how absurdly smart she is because she doesn’t have any of the usual “smart” interests. She is wholly focused on arts and nature. Nor does she ever show it off.

This fantastic being simply wants to stay in her house in the woods, crafting wonderful things while being surrounded by animals.

I have a buddy that’s basically illiterate. He calls me to write emails for him because he can’t even quote people on paper. If you met him you’d probably think he was mentally challenged because he just struggles with things like reading, writing and math. My favorite texts from him are the “wife n me at restrnt, how much bill? Tip$$$??” With a picture of the receipt and I’ll literally respond with a picture of what to write so he can copy it.

But I will tell you this guy is a genius. If you call him with an issue with a car you can hold the phone up to the sound and he will rattle off exactly what’s wrong, call the auto parts store for you and order everything you need then come fix it. He also taught himself to weld, and he literally builds extravagant trailers from scratch. Literally anything that I’ve ever seen broken this guy can fix back to better condition than it was new. It’s truly amazing.

Just recently this guy bought a busted up boat, completely repaired it, rebuilt the engine and we went out on it. He had never done fiberglass work before, never worked on a boats components before and it was perfect.

I don't know if this counts, but my daughter.
I know every mother thinks their children are geniuses, but I also have a son 15 months younger, and he's clever of course — but hear me out.

We first noticed our daughter was gifted when she started to mimic people. At about 7 months old, she met my father for the first time, who was living in a nursing home. We took him outside so he could have a cigarette. Later that evening, I noticed her holding a spoon to her mouth, drawing in a breath, pulling it away and exhaling mimicking smoking exactly as she’d seen. I was fascinated and honestly thought I was imagining it.

As she grew, her capabilities kept surprising us. When she began crawling and walking, she started climbing out of her cot in the early hours of the morning, turning on the TV by herself. Most mornings we would find her watching Chinese news. If we changed it to cartoons, she cried until we changed it back. It became very clear she was choosing that channel deliberately.

She toilet-trained herself as soon as she started walking, around 13 months old. No bribing, no charts, just watched me a few times and did it herself from there on out.The mimicking continued, she'd settle up next to her nan, pulling her pen out and circling things in papers before she could even read.

At 2, she asked for a stethoscope. I didn’t know what one was at the time, I mean I had idea but she had to explain it was what doctors use to listen to heartbeats (she insisted she wanted one like the one she used to have - but thats a whole different story). We assumed she must have heard the word somewhere, but she insisted she needed one. Most children her age were watching Peppa Pig and The Wiggles but she preferred documentaries about surgery and was fascinated by the human body. At 3 she could beat anyone she encountered at checkers.

When she was 4, she told me preschool was “for babies” and she wanted to go to big school. Out of curiosity, I had her assessed at a private school. They confirmed she was ready and already ahead of most children her age for reading and writing. She started school, and before we knew it she was entering and winning state public speaking competitions.

When she entered Year One at 5 years old she was already a year younger than her classmates but topping the class. They placed her on Year 3 work, and she was outperforming even them in maths and English.

Her teacher at parent teacher interviews what we did for a living. anf said other staff had asked if we were rocket scientists. Neither of us even finished school. My husband left after Year 10, and I grew up in an environment where girls were not encouraged to pursue education. I attended just enough days to avoid failing and was kept home the rest to cook and clean.

She’s now 6, and the school genuinely doesn’t know what to do with her. She has taught herself the local Aboriginal language using school resources, and speaks it fluently. She is learning French, and once she’s done, she wants to learn Japanese. In our last parent-teacher interview, it was suggested we let her use AI to explore her questions further because her thinking is already beyond what teachers can answer without researching. I’ve been Googling for years; she outgrew everything I know a long time ago.

The school has considered moving her up grades, but we’ve tried to prioritise her childhood. She reads chapter books for fun and is so far ahead academically that they won’t assign her homework. When she borrows books from the library, she always borrows the one the library teacher reads to the class, after she did this a few times in a row, I asked why she borrows the same books they've already read, and she told me that when the teacher reads it, she doesn't get the expression right, so she likes to borrow the book so she can read it with the expression its supposed to have.

She has this ability to be shown something once and then she can do it herself. I don’t know what her future holds, but I suspect she has a photographic memory or very close to it. In memory games she never misses. Once I watched her kind of look above my head as if she was looking at a board behind me for answers, I asked her what she was doing and she said she was looking at the pictures in her brain.

And emotionally, she is more mature than most adults I know.

Yep. I knew a guy in high school who was insanely smart. He was bored in school so he didnt ever apply himself and his grades were awful. But he was incredibly quick and excellent at problem solving. He was also the funniest person I've ever met. Even the teachers saw how intelligent he was but knew he would never pay attention in class so they used to negotiate deals with him to ensure he still passed while doing minimal work. He once took a class where he only had to show up 6 times in a year (1st day of both semesters, midterms, and finals) and so long as he handed in his homework the teacher agreed to give him a C.


He ended up dropping out of college (he only went to appease his parents) and got a job as a bartender. From there he worked his way up and now he owns multiple restaurants. Dude finally found a place where he could use his brains and wasn't bored.
