The Chilling Truth Behind Isolation Experiments: What Happens In Your Head?!
Loneliness. Most of us, we think of a chill spot. A bit of quiet, maybe escape the daily grind. Kick back and just think. We relax. Get real. Our imagination goes hella wild. But nope, that’s not the vibe here. We’re getting into something way more intense: total, brutal social isolation. For ages, scientists set up some messed-up isolation experiments. Always showing harsh stuff about our brains.
Nah, this isn’t just being alone for a bit. We’re talking totally cut off. Ripped away from everything familiar. No phone. No internet. No nature. No other humans. They’ve studied it forever. Tried it a million times. And, scary thing, it’s torture material a lot. The results? Mind-bending. Wanna see what the human brain really does? How it crumbles? How someone just… changes? Lock ’em in a room.
Total isolation, even when comfy, is just plain mental torture
Get this messed up story. Sarah Shourd, an American tourist. Her fiancé, a friend. They accidentally stumbled into Iran. Iranian security forces grabbed ’em, called ’em spies. Shourd got 15 months alone. Not much human contact. She later said in 2011, “the worst part was the loneliness.” Heard voices. Saw people. Total head games.
And another thing: Even if you choose to be antisocial, just a little bit of contact? It’s bad for you. Studies always show: folks who pick being super alone get higher blood pressure. They get sick more. Bigger Alzheimer’s risk. Their internal clocks get messed up, too. Can’t sleep. Can’t focus. Make stupid decisions. If just choosing loneliness does all that? Picture total, forced isolation.
No senses? Your brain makes things up, seeing stuff that ain’t there
So, back in the 50s and 60s, psychologists did some wild isolation experiments. Dr. Donald Hebb at McGill University, he paid people. To just lie there. In quiet, sensory-deprived rooms. No human contact. Nothing to hear, nothing to feel. Zero input.
Some guys bailed in just hours. Others? Started yammering to themselves. Reciting poetry. Singing. Or just got super anxious. But the craziest stuff? Always the hallucinations. Folks saw squirrels. Flying glasses. Dogs, even babies. One participant swore they heard a music box. Another felt an electric shock just touching a doorknob! The researchers hoped to keep going, but hardly anyone lasted more than two days. Max.
Then, a more recent 2008 isolation experiment, with the BBC, showed the same thing. Six brave volunteers spent 48 hours in old nuclear bunkers. Totally dark and silent. What happened? Anxiety, panic attacks, paranoia. Seeing messed-up stuff. Some saw piles of oyster shells. Others saw snakes, or zebras. One dude even felt a breeze, but nope, no ventilation.
But why does your mind play such stupid tricks? Because when your brain’s circuits – the bits that handle sights, sounds, and what’s around you – when they’re starved of real-time data? They don’t just shut down. They create. They literally invent stimuli. Or make up a fake reality from next to nothing. It’s just a basic need for input, man. And without it? That brain just goes wild.
We need other people. Seriously. No one around? Your head goes bad
We’re built to be social, plain and simple. It’s what makes us human! Think about language. It didn’t pop up alone, right? Needed people working together. Emotions? Moral rules? Right and wrong? All of it. Comes from being with others. Take away that give-and-take network, and we just lose our way. Seriously.
They’ve studied isolation for lots of reasons. Like, astronaut heads and how to grill people
The reasons for these isolation experiments? All over the place. And not always for good reasons. In 1993, NASA hooked up with Maurizio Montalbini, a sociologist. They wanted to get how space missions messed with astronauts’ heads. Montalbini spent 366 days in a cave near Pesaro, Italy. No clocks, no calendars. When he came out? He thought only 219 days had passed. His internal clock? Shattered. He said his days felt like 48 hours – 36 awake, 12 asleep. Isolation totally screws with time perception, man.
On the darker side? The 1950s and 60s. China used “isolation torture” to brainwash American POWs during the Korean War. Both the U.S. and Canada, they funded research into these tactics. Maybe to get how it worked, or even try it out themselves. What everyone understood? Isolation broke people. Plain and simple.
Some people handle isolation better. Mental games, a reason to live, and knowing help is coming? That helps a lot
But not everyone just gives in! Hussain Al-Shahristani, for example. He ran Iraq’s nuclear thing under Saddam Hussein. Saddam wanted an atomic bomb. Al-Shahristani? He refused. Thought it was wrong. His punishment: almost ten years. Torture. And total isolation, locked up in Baghdad’s nasty Abu Ghraib prison. He kept his mind together by constantly creating and solving complex math problems. Just in his head. Today, he’s Iraq’s Deputy Energy Minister. Wild.
Edith Bone, a translator stuck by Hungarian communists in WWII, she found her own way to cope too. All alone, she made an abacus out of breadcrumbs. Then counted every single word she knew in her six languages. Wild, right? American Senator John McCain, an old soldier, he went through 5.5 years as a POW in Vietnam. Wouldn’t break from interrogation. It made him stronger. Gotta say, military people often handle this stuff better. Thanks to their training. And knowing their buddies were fighting relentlessly to get them out.
Then there’s the 1968 Sunday Times Golden Globe yacht race. An interesting, but sad, story. Nine solo sailors tried to sail around the world. Robert Knox-Johnston finished in 313 days. The only one to pull it off. But two other guys’ tales? Really say something.
Bernard Moitessier, one of the competitors, he found total bliss being alone. So much so? He quit the race! Just left it. Kept sailing. Didn’t care where he was going. Ended up in Tahiti, chillin’. Happy. “It was an incredible experience; I found myself,” he said.
Donald Crowhurst, though? Way worse end. Problems from day one. He lost his way, just drifted. Depressed. Consumed by loneliness. He hid in his cabin. Wrote 25,000 words of crazy philosophical rambling. Then just took his own life. Middle of the ocean. His body? Never found. These stories show that isolation is real torture. But a strong imagination, a fierce purpose? They can sometimes break through it.
Right and wrong? We learn that from other people
Yeah, we heard this already. But it’s true: without that constant back-and-forth from other people, our inner moral compass? It gets messed up. What’s right? What’s wrong? Those answers don’t just pop into your head all on their own. They’re built from community. From empathy. From seeing how everyone acts, what people value. You take away that outside guide, and we can totally lose our footing.
