12 real scientific facts that sound completely made up, but aren't
Did you know that placebos work even when people know it's a placebo?

Real life is far stranger than fiction.
And now we have the proof.
A recent thread on r/AskReddit posed the question: "What sounds like pseudoscience, but actually isn't?"
The answers were far more interesting than all the science classes I ever took. Combined.
Let's take a look at some of the strangest scientific facts the good people of the Internet could come up with.
1. Phantom limbs & mirror therapy
Most people have heard of phantom limbs and phantom limb pain, the phenomenon where someone who's lost a limb can still feel pain or other sensations where the missing appendage should be.
But the connection between the brain and the missing limb gets even wilder the more you dig into it.
Did you know that a common treatment for phantom limb pain is something called "mirror" therapy, where a therapist will use a series of mirrors to make it look like the missing limb is still there? This tricks the brain and eases discomfort over time.
Sounds like psuedoscience, but can be extraordinarily effective!
Tip of the cap to u/MonSoleil937 for this one.
2. Ear crystals going haywire

User u/shinjithegale nominates "Benign Paroxysmal Positional Vertigo", or BPPV, a common type of vertigo and dizziness that usually occurs in people over the age of 60.
The weird part? The vertigo is caused by small calcium crystals inside the ear coming loose and flowing into the inner ear.
"Your magical ear crystals are out of sync" definitely sounds fake but is 100% a real, treatable condition.
3. Redheads need more anesthesia than everyone else
This one comes from u/explorerdoraaaaaa — and it can't possibly be true, right?
Wrong.
Red-haired people, who make up only about 2% of the population, may process pain differently from the rest of us and have been shown to often be more tolerant to local anesthetics — they may need up to a 20% stronger dose!
They might also be more sensitive to opioids and less sensitive to shots, needles, and electric shocks.
4. Speaking in a different language can unlock an alternate personality
Where are our personalities stored? In our brains? Our souls?
Despite sounding completely implausible, maybe neither!
If you learn a new language or grow up speaking multiple languages, your personality make be markedly different depending on which language you're speaking.
One study gave people who grew up in Spanish/English bilingual households a personality test in each language and found that their values and personality traits were dramatically different in the respective results.
5. Platypuses exist

That's it. That's the fact, courtesy of u/Steeze-Schralper6968.
The list of true but baffling facts about platypuses goes on and on.
For starters, they're a mammal with a beak that lays eggs, sweats milk, and shoots poison.
If you read about it in a SciFi novel you'd struggle to suspend your disbelief.
6. Duct tape can cure warts for some reason
Most common warts are harmless, but we still don't like having them. That said, because they're not hurting anyone people are hesitant to try invasive or expensive procedures to remove them.
Enter Duct Tape Occlusion Therapy, which is a real thing. Simply apply duct tape to the wart, remove, clean the area, and repeat every couple of days.
Weirdly duct tape therapy isn't just ripping the warts off. There's some evidence that the adhesive used on the tape may cause an immune response in the skin that causes the warts to clear up.
7. The world is brighter for blue-eyed people — and they see better at night

I've always wondered why I can barely walk outside on a cloudy day without sunglasses, and now I know!
8. Eye-Movement Desensitization and Reprocessing
EMDR therapy, nominated in the thread by u/taurussy, sounds like something you'd see a stage hypnotist perform on tipsy audience members.
In reality, it's a powerful therapy for processing trauma.
EMDR involves a patient processing traumatic memories while performing therapist-directed eye movements or otherwise tracking an external stimulus, like a light or an audio track.
The theory is that the process can form new connections between blocked-off and painful memories and more adaptive memories or information, which allows for healing.
9. The placebo effect & open-label placebos
Most of us know about the placebo effect, but it's still almost too unbelievable to be real.
(As a refresher, an example of the placebo effect might be someone with a cold feeling better after taking a "sugar pill" with no medicine in it that they were told would cure them.)
But here's something wild you probably didn't know about placebos:
They can work just as well even when people know they're taking a placebo!
The things our brains can "trick" us into doing are truly incomprehensible.
10. Teratomas
Teratomas sound more like nightmare-fuel than psuedoscience, but they're still worth a mention from u/flugualbinder.
Teratomas are rare kinds of tumors that can grow and contain hair, bones, muscle, and even teeth.
They are real, and you will look up photos of them at your own peril.
11. Pain is all in your head — kind of
Pain is real, and it's valuable information for your body that something is wrong.
But scientists have learned a lot about it, specifically when studying chronic pain. And we know now that our emotions, our beliefs, and other aspects of what happens in our brains plays a big role in how we experience pain.
One study found that Pain Reprocessing Therapy (PRT), basically training the brain to "unlearn" pain, was more effective than a placebo and normal pain management care.
It gives credence to something that sounds completely unbelievable: In some cases, you can "mind over matter" your way to hurting less.
12. Grass screams when you cut it
Thank you to u/arealcabbage for this horrifying image:
"The grass screams distress signals to the next lawn over when you're mowing."
Believe it or not, that's true — in a sense. That freshly-cut grass smell we all like? It's actually a distress signal designed to warn other plant-life in the area of danger.
It's a stretch to say that your lawn feels pain, but it does have some survival instincts. Now if we could only say for sure why humans love the smell so much!
There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
