There are moments in life when someone says something so bafflingly wrong that your brain briefly stops working. Sometimes it’s actually a grown adult confidently asking if the moon is turned off during the day, or someone trying to microwave metal like it’s perfectly reasonable.
Whatever the situation, these encounters tend to stick with you forever, not because they were malicious, but because they were so spectacularly clueless that you almost have to admire the confidence behind them. And when people online were asked to share the exact moment they realized someone was genuinely unintelligent, the responses did not disappoint.

When my father-in-law d**d suddenly, my wife and another family member were scrambling to assemble important records to tend to his affairs. With my mother-in-law medically indisposed, she was unable to help.

One thing we needed was the deed to their home. We didn't know where it was. We thought the county clerk office could help.

A panicky looking guy at the clerk's office explained that my father-in-law, being the sole homeowner, is the only one who can make the request. We told him that my FIL was d**d. He looked increasingly panicked. He said, "I don't think other family members can make the inquiry."

We asked what the procedure was in case someone d**d. He said he was not aware of that happening. We asked if my father-in-law was the first person in a town of over 100,000 people, a town first settled in 1651, to ever d*e.

He seemed to come to his senses. We re-iterated our question, and he looked panicked once again. "Is there any chance your father-in-law himself could make the request?"

It was truly a unique experience.

Food was banned on the call floor, but the person in the cubicle across from me was surreptitiously eating peanuts. I couldn't figure out why I was suddenly itchy and developing hives, until I stood up to go to the bathroom and she saw me and freaked out, apologizing and asking if I'm allergic.

So I went to my manager and said I'm having an allergic reaction to peanuts, so and so was eating some and she's really sorry, she didn't know, so I'm going to go home and take Benadryl now.

He asked me if I'd eaten any peanuts. I said no, so and so was eating peanuts. He said I couldn't be having an allergic reaction then, so I didn't need to go home.

I held out my arms and showed him my hives. I told him my eyes were itchy and my face was burning and I needed to go home and take inadvisable amounts of Benadryl now.

He repeated that it was not possible that my symptoms were an allergic reaction because I had not eaten any of the peanuts.

I said okay, I need to go home and treat my mystery symptoms. He said no, of my symptoms were a mystery I shouldn't know how to treat them, so I might as well stay.

I thought about it for a second, then asked him how he thought cat allergies worked. Did he think people ate cats. Or did people with cat allergies develop symptoms from being in the same room as cats.

He asked if I was claiming there was a cat on the call floor.

I said no, I was having an allergic reaction to peanuts in the same way people have allergic reactions to cats.

He reiterated that you cannot have an allergic reaction to peanuts without eating them, and that there are no cats on the call floor.

Which was when I gave up and said I was going home now and I'd see him tomorrow. When he wrote me up for unexcused absence.

I was having a conversation with a former colleague and I had mentioned that I had gone to a WWI museum that’s in Germany and how I was planning on going to Belgium to see the WWI trenches. With the most straightest face possible, they said, “Belgium isn’t a real country. It’s a make believe country to scare people into thinking the a global war is real. WWII was also fake because there’s no such thing as Egypt” I’m not kidding.

One reason moments like these tend to stick in people’s minds is that confidence often has more impact than accuracy. As explained by Verywell Mind, people frequently overestimate their own intelligence or knowledge due to cognitive biases that distort self-perception.

One of the key explanations is the Dunning-Kruger effect, where individuals with limited ability in a certain area may lack the awareness needed to recognize their own mistakes, leading to inflated self-assessments. On top of that, illusory superiority can push people to believe they are above average in many everyday skills by favoring information that supports what they already think.

Helping a friend fill out paperwork online, he tells me that he doesn't know his dad's name, he hasn't seen him since he was little and he only knew him as "dad", he has no clue what his name could be. Then he signed his name with junior at the end. I said "junior?" And he said "yeah, I'm a junior, I'm named after my dad.".

There is also an important distinction between intelligence and common sense, which Psychology Today highlights as two very different abilities. Intelligence is generally associated with abstract reasoning, learning complex concepts, and solving unfamiliar problems, while common sense refers to practical judgment shaped by everyday experience.

What feels obvious or logical is not universal, since background, education, and culture all influence how people interpret situations. Because of this, what seems like basic logic to one person can feel completely unfamiliar to another, especially when cognitive shortcuts, overconfidence, or information overload interfere with clear, intuitive judgment.

Guy I already thought was a moron in response to me complaining about having a headache: "I don't get headaches. My dad was a physician and he told me I don't have a frontal lobe so I can't get them.".

In a world before cell phones updated time automatically during daylight savings time, I had a conversation with a guy complaining about getting up at 2 to set their clock back. I laughed, thinking he was joking and mentioned that I simply set my clock before I go to sleep. He actually began to argue with me that DST started at 2am not 10 pm the night before. I gave him my best "By Jove, I do believe you're right" face and just noped out of that conversation real quick.

True story. Just think, somewhere out there, people like this are voting, driving on our freeways and having children.

When my incel cousin tried to explain to me (a pregnant woman)
That women are evil and a lot of them have late term abortions around (7 to 8 months) to spite the man that got them pregnant.

Then when I said name ONE.

HE SAID, A LOT OF WOMEN, TOO MANY TO NAME.

🥴

Obviously we don't speak anymore but like 👁👄👁.

Another layer comes from the difference between being uninformed and being unintelligent, as noted by educator Dan Harkey. Lack of knowledge often comes down to missing information or limited exposure, which can change with learning and experience.

Cognitive ability, however, is described more as a deeper capacity for reasoning, adaptation, and problem-solving. At the same time, what people assume is "common knowledge" is heavily shaped by upbringing and education, meaning that different environments produce very different expectations about what should be obvious.

Saw them ask a lady how she knew Spanish. The lady said “because that is what I grew up speaking.”

They said “you don’t look Mexican tho.”

While speak to a woman I know I mentioned that Jesus was supposedly a carpenter. "That can't be true", she said, "they didn't even have carpets back then".

...which is incorrect on multiple counts.

My ex after a few months dating.
Randomly tells me that North Pole doesn’t exist, it’s just advertising from Coca Cola. I laughed of course, thinking she was joking. She was not. I spent hours explaining that there are in fact two poles. One in the north and another in the south and somehow she insisting that she didn’t understand how could there be one in the north if south already had one pole. I never understood her point. But I made drawings to explain.

Finally, people do not always respond to being wrong in a straightforward way. Research from Tava Health explains that when beliefs are challenged, it can create cognitive dissonance, a psychological discomfort that comes from holding conflicting ideas.

Instead of adjusting their view, individuals may reject new information or reinforce their original belief to avoid that discomfort. Since admitting a mistake can feel like a hit to self-esteem or identity, especially when others are present, defensive reactions like denial or justification often take over, making some positions harder to change even in the face of clear evidence.

I was dating a doctor. And in hindsight, it was clear that my making more money than him really upset him. But we were having a conversation, and I told him some good news about a promotion I had gotten at work. And he immediately switched the topic to telling me that my pots and pans were giving me cancer. And I was like, "What!? Wait, where are you getting that information?" And he was like, "A scientist!" And I was like, "Who?" 10 mins later, he finally showed me a TikTok video from some random guy (not a scientist). And it wasn't even about my pans, but a completely different brand. And I was like, "Uhhh, don't you like diagnose cancer for a living?"

It was like the veil lifted from my eyes, and I saw him as a complete doofus from there on out. I broke up with him a month later.

Mind you. This man didn't believe in wearing sunscreen.

I was having a conversation with someone and said that pro choice doesn’t necessarily mean my own personal belief is for abortion, it means I believe others get to make that decision for themselves.

He said it was impossible.

I told someone I was a sign language interpreter and they asked if I knew how to read the braille that was nearby. When I explained what sign language was and that it’s primarily used for Deaf people, he said I should learn “just in case”.

Moments like these are unforgettable because they remind us just how unpredictable people can be. As painful as these interactions can be in the moment, they also tend to become the stories people laugh about for years afterward. Of course, intelligence comes in many forms, and everyone also has their occasional "no thoughts, head empty" moment.

Still, the stories in this thread stand out because the people involved were often completely convinced they were right, which somehow made everything even funnier. Do you want to see the kinds of comments that made strangers instantly lose faith in humanity? Keep scrolling for some of the most ridiculous, baffling, and unintentionally hilarious responses the internet had to offer!

My mil.. I don’t know to call it stupidity or superstitious. She genuinely believe that women washing their undies in the same washer as men causes men bad luck and is the reason why their men can’t get rich. She has never washed her undies in the washer and her husband still isn’t rich.

This is not THE moment for this guy, just one of many, but it's a personal favorite.

When "Walking D**d" was at it's peak, I had a friend get into it a few seasons late, I wanna say when 4 came out. So I offered to wait to watch the new ones that were airing, and let him catch up to where the show was at at the time, so we could watch together every week going forward.

He binges S1 and 2 ASAP. Constantly texting me how he loves Daryl and Rick and this plot and that, etc etc. I'm replying "I know, right? Just wait for blah blah"

Anyway, his texts start getting weird. He's mentioning characters that aren't on the show, plots that never happened. Says he doesn't understand why the show dropped Rick and Andrea and he doesn't like this new cast. At some point I come out and ask what the hell he's talking about.

Come to find out this man, who watched 1 and 2, knew it inside and out, at some point started watching "Z Nation" instead, getting ***3 f*****g seasons in*** and never once realizing it wasn't Walking D**d.

When instead of genuinely finding out why their cat is peeing places that is not the litter, they say it’s because the cat is Virgo.
Still face palming. Do you want to keep complaining that the cat is peeing on your bed or not.

Unintelligent or lacking critical thinking skills?

My cousin is a flat earther. He's really good at math, so I offered to walk him through the equations used to prove the world is round thousands of years ago.

We did the calculations, by hand, for a 100 level logic class in college.

He refused.
