Science can be fascinating, right? But sometimes, in the pursuit of knowledge, things get a little…weird. When I first stumbled upon some of these experiments, my first reaction was a mix of disbelief and curiosity. I mean, who thinks of putting pigeons in missile control systems or dosing an elephant with LSD? Yet, here we are, diving into the bizarre world of experiments that really pushed the boundaries of “normal.”
Now, before anyone starts wondering why anyone would even attempt some of these experiments, let’s be fair, curiosity has driven some of the greatest discoveries in history. Sure, not all of them ended with Nobel Prizes, and some definitely crossed ethical lines, but they’ve all made their mark in the weirdest chapters of science.
Some of the experiments on this list are downright hilarious, while others are a little unsettling. But they all have one thing in common, they’ll make you wonder, “What were they thinking?”
1. The Stanford Prison Experiment
Back in 1971, psychologist Philip Zimbardo wanted to understand the psychological effects of perceived power, so he set up a simulated prison in the basement of Stanford University. He split college students into two groups, guards and prisoners. What started as an innocent role-playing experiment spiraled into chaos. The guards became sadistic, and the prisoners? They ultimately cracked under the pressure.
What was supposed to last two weeks ended after just six days, and the results still serve as a chilling reminder of how quickly we can lose our moral compass when given power. It’s no wonder this experiment is now used as a case study for how not to conduct research.
2. Milgram’s Obedience Study
Stanley Milgram wanted to know just how far people would go when following orders, even if it meant harming someone else. So, in the early 1960s, he designed an experiment where participants were told to administer electric shocks to a “learner” (who was actually an actor) whenever they got an answer wrong. The shocks increased in intensity, and despite the actor’s cries of pain, many participants kept going, just because someone in a lab coat told them to.
The results were shocking, pun intended, with 65% of people delivering the maximum voltage. The experiment raised some serious ethical questions about authority and human behavior.
3. Little Albert Experiment
In 1920, psychologist John Watson conducted one of the most unethical experiments in history. He wanted to see if fear could be conditioned into a child. Enter “Little Albert,” an infant Watson subjected to loud noises while showing him various animals. Soon, the poor kid became terrified of anything furry, even a white rabbit.
The ethical violations here are glaring, and to this day, no one knows what happened to Little Albert. The study did teach us about conditioned fear, but at what cost?
4. Project MK-Ultra
This one’s straight out of a conspiracy theorist’s handbook, but it’s all too real. MK-Ultra was a secret CIA project in the 1950s and 60s that aimed to develop mind control techniques, often using unknowing participants. The agency tested everything from hypnosis to LSD, sometimes on people who had no idea they were part of an experiment.
The project left many participants with long-lasting trauma, and when the details came to light, it rocked public trust in the government. To this day, the full extent of MK-Ultra remains a mystery since many of the records were conveniently destroyed.
5. The Monster Study
In 1939, speech pathologist Wendell Johnson conducted what would later be known as “The Monster Study.” He wanted to see if negative reinforcement could cause stuttering. To do so, he took 22 orphans and gave half of them positive feedback on their speech and the other half harsh, critical feedback. The result? The children who received negative feedback developed speech problems, some for the rest of their lives.
The study’s ethical failings are obvious, and its name is a testament to just how monstrous it truly was.
6. The Pit of Despair
In the 1970s, psychologist Harry Harlow’s research on monkeys and social isolation took a dark turn. Harlow placed baby monkeys in a device he chillingly called the “Pit of Despair,” isolating them for extended periods. The results were predictable and heartbreaking, the monkeys became severely depressed, socially withdrawn, and in some cases, never recovered.
While his work provided insights into the effects of social deprivation, it’s widely condemned today for its cruelty.
7. The Three Christs of Ypsilanti
In the 1950s, psychologist Milton Rokeach brought together three psychiatric patients, each of whom believed they were Jesus Christ. He thought that by interacting with one another, their delusions might break down.
Instead, the three men ended up arguing with each other, each claiming the others were imposters. While the experiment is remembered for its bizarre setup, it’s also a reminder that mental illness can’t always be cured by simply forcing someone to confront their delusions.
8. Elephant on LSD
In 1962, scientists at the University of Oklahoma decided to see how an elephant would react to LSD. They gave a bull elephant named Tusko an enormous dose, nearly 1,000 times the typical human amount. Unsurprisingly, the experiment ended in tragedy when Tusko collapsed and died shortly after.
The experiment’s senseless cruelty sparked widespread criticism, highlighting the dangers of reckless experimentation.
9. Robo-Rats
In 2002, researchers implanted electrodes into the brains of rats, allowing them to control the rats’ movements with a remote control. These “robo-rats” could be directed through mazes and even made to climb walls.
While the experiment had potential applications for search and rescue missions, it also raised ethical concerns about the extent to which we should manipulate living creatures.
10. The Landis Facial Expression Experiment
In 1924, psychologist Carney Landis tried to find out if different emotions produced universally recognizable facial expressions. He had participants perform various tasks, from smelling ammonia to decapitating a live rat. Most people didn’t want to kill the rat, but many did it anyway when prompted by the authority figure conducting the experiment.
The study didn’t lead to any groundbreaking insights about emotions, but it sure showed how far people will go under pressure.
11. Twins Reared Apart Study
In the 1960s, a secret study separated identical twins at birth and placed them in different adoptive families to see how much of their development was due to nature versus nurture. The twins were unaware of each other’s existence and were observed by researchers for years.
When the twins later discovered the truth, many were understandably upset. The study raised serious ethical questions about experimenting with human lives, especially without informed consent.
12. Project Pigeon
During World War II, psychologist B.F. Skinner proposed using pigeons to guide missiles. His idea was to train the pigeons to peck at a target inside the missile’s nose cone, steering it toward enemy ships. Though the pigeons were remarkably good at it, the project was eventually scrapped in favor of more advanced technology.
Still, the idea of pigeons being missile pilots sounds like something straight out of a wacky sci-fi movie. Skinner’s “Project Pigeon” may not have taken off (pun intended), but it stands as one of the strangest military experiments ever proposed.
13. The Cat Brain Transplant
Dr. Robert White took things to a new level of weird in the 1970s with his monkey head transplant experiment. He attempted to transplant the head from one monkey into another to see if it could be revived. Surprisingly, the experiment somewhat worked, and the monkey was able to hear, smell, and see, but it wasn’t able to move at all.
While White’s work contributed to advancements in brain surgery, this particular experiment was widely criticized for pushing the limits of acceptable animal testing.
14. The Two-Headed Dog Experiment
One of the most infamous experiments from the Soviet Union came courtesy of scientist Vladimir Demikhov in the 1950s. He successfully transplanted the head of a small dog onto the body of a larger one, creating a two-headed dog. Both heads were able to function independently, though the experiment didn’t last long as the dogs soon died.
Demikhov’s work was intended to advance organ transplant techniques, and while his research did pave the way for some medical advancements, the ethics of creating such a creature left people questioning whether the ends justified the means.
